Legal and Tax Issues When Starting a Business: 12 Essentials

Starting a business in the United States involves more than developing a product, selecting a name and attracting customers. Understanding the Legal and Tax Issues When Starting a Business is essential because a new company must operate within federal, state and local rules covering business formation, taxation, ownership, employment, intellectual property, licensing, contracts, privacy and ongoing reporting.

Understanding the most important legal and tax issues when starting a business can help founders protect personal assets, avoid penalties, preserve valuable tax benefits and build a company that customers, lenders, employees and investors can trust.

The correct legal and tax approach depends on the business. A solo consultant may have very different obligations from a restaurant, construction company, online retailer, software startup or employer operating in several states. The company’s location, industry, ownership, workforce, revenue model and growth plans all affect the rules that apply.

This guide explains 12 essential legal and tax considerations for launching a U.S. business in 2026. It also covers frequently overlooked subjects such as founder vesting, Section 83(b) elections, qualified small business stock, sales-tax nexus, worker classification, cybersecurity and formal business closure.

Quick Answer: Legal and Tax Issues When Starting a Business

The main legal and tax issues when starting a business include choosing the correct entity, registering the company, documenting ownership, protecting intellectual property, obtaining licenses, applying for tax identification numbers, understanding federal and state taxes, classifying workers correctly, using written contracts, protecting customer data, purchasing insurance and maintaining ongoing compliance.

Before accepting payments, hiring workers or signing major contracts, a new business should generally:

• Choose a legal structure and federal tax classification.
• Register the entity and any assumed business name.
• Prepare ownership and governance documents.
• Check the proposed brand for trademark conflicts.
• Obtain applicable federal, state and local licenses.
• Apply for an Employer Identification Number when required.
• Open a separate business bank account.
• Establish bookkeeping, payroll and tax procedures.
• Use written customer, vendor and worker agreements.
• Protect intellectual property and confidential information.
• Purchase appropriate insurance.
• Create a recurring compliance calendar.

A company’s structure affects taxation, registration, fundraising and personal liability. Most businesses must also obtain tax identification numbers and applicable licenses before beginning operations.

Key Takeaways

• An LLC is a state-law entity, not one specific federal tax classification.
• Forming an LLC or corporation does not eliminate every type of personal liability.
• Registering a business or domain name does not automatically create trademark rights.
• Federal taxes are only part of business compliance; state and local obligations may be equally important.
• A worker does not become an independent contractor merely because an agreement uses that label.
• Several startup tax elections have short filing deadlines.
• Domestic U.S. entities are currently exempt from federal beneficial ownership reporting.
• Founder shares, options, SAFEs and other investment interests can create tax and securities-law obligations.
• Separate finances and organized records support both tax reporting and liability protection.
• Legal and tax compliance continues after the company launches.

1. Choose the Right Business Structure

Choosing a business structure is one of the first major decisions a founder makes. It affects personal liability, ownership rights, tax returns, management authority, fundraising options and administrative costs.

The most common U.S. structures include:

• Sole proprietorship
• General partnership
• Limited liability company
• C corporation
• S corporation
• Limited partnership
• Limited liability partnership
• Professional corporation or professional LLC

An S corporation is a federal tax status rather than a separate state-law entity. An eligible corporation or LLC may request S corporation treatment by filing Form 2553.

Business Structure Comparison

Structure	Ownership	Liability Position	Default Federal Tax Treatment	Common Use
Sole proprietorship	One owner	No separate liability barrier	Reported on the owner’s individual return	Freelancers and small solo businesses
General partnership	Two or more owners	Partners may be personally liable	Partnership pass-through taxation	Small businesses with active co-owners
Single-member LLC	One member	Limited liability when properly maintained	Usually disregarded for income tax	Solo owners seeking legal separation
Multi-member LLC	Two or more members	Limited liability when properly maintained	Usually taxed as a partnership	Flexible closely held businesses
C corporation	Shareholders	Shareholders generally have limited liability	Corporation pays its own income tax	Venture-backed and scalable companies
S corporation	Eligible shareholders	Depends on the underlying entity	Pass-through taxation	Profitable owner-operated companies
Limited partnership	General and limited partners	Depends on each partner’s role	Usually partnership taxation	Investment and real-estate ventures

LLC Legal Status Is Different From Tax Status

A limited liability company is created under state law, but federal tax law can classify it in several ways.

A domestic single-member LLC is generally disregarded as separate from its owner for federal income-tax purposes unless it elects corporate treatment. A domestic LLC with two or more members is generally treated as a partnership unless it elects corporate taxation.

An eligible LLC may also elect S corporation status.

An LLC can therefore potentially be taxed as:

• A sole proprietorship
• A partnership
• A C corporation
• An S corporation

The letters “LLC” do not reveal which federal tax return the business must file.

Liability Protection Has Limits

An LLC or corporation may protect its owners from many company debts and contractual claims, but that protection is not absolute.

An owner may still face personal liability when the owner:

• Personally guarantees a loan, lease or credit account.
• Commits fraud or another wrongful act.
• Injures someone through personal negligence.
• Mixes personal and business funds.
• Uses the company as a personal bank account.
• Improperly transfers assets away from creditors.
• Fails to maintain required entity formalities.
• Becomes responsible for certain unpaid payroll taxes.
• Signs a contract in an individual capacity.

Banks, landlords and suppliers may also require personal guarantees from new companies with limited assets or credit history.

Entity formation should therefore be combined with separate finances, proper records, written agreements, responsible governance and adequate insurance.

When a Sole Proprietorship May Be Suitable

A sole proprietorship is generally the default structure when one person conducts business without creating a separate entity.

It may be practical for a low-risk activity with:

• One owner
• No employees
• Little borrowing
• Limited contractual exposure
• No outside investors
• Few valuable business assets

However, a sole proprietor may still need a DBA registration, local permit, professional license, sales-tax account, EIN and insurance.

The main disadvantage is that the owner and the business are generally the same legal person.

When an LLC May Be Suitable

An LLC is commonly used by consultants, agencies, online businesses, property owners, family companies and professional-service firms.

Potential advantages include:

• State-law liability protection
• Flexible ownership
• Flexible management
• Several potential federal tax classifications
• Fewer formalities than many corporations

A multi-owner LLC should have a detailed operating agreement. Even a single-member LLC can benefit from an agreement documenting the company’s management, ownership and separation from the owner.

Professional Entities

Some states require licensed professionals to use a professional corporation, professional association or professional LLC.

These rules may apply to:

• Attorneys
• Physicians
• Dentists
• Accountants
• Architects
• Engineers
• Psychologists
• Other licensed professionals

A professional entity may protect an owner from some company obligations, but it normally does not eliminate liability for that professional’s own malpractice.

State licensing boards may also restrict who can own, manage or provide services through the entity.

When a C Corporation May Be Better

A C corporation may be preferable when a company expects to:

• Raise venture capital.
• Issue preferred stock.
• Grant employee stock options.
• Add institutional investors.
• Retain substantial earnings.
• Pursue a stock-based acquisition.
• Eventually become publicly traded.

C corporations may face income tax at the company level, followed by shareholder tax when profits are distributed as dividends. However, investor expectations, equity incentives, qualified small business stock planning and exit strategy may outweigh this disadvantage.

When S Corporation Taxation May Help

S corporation treatment may benefit a profitable owner-operated company because qualifying income generally passes through to shareholders.

However, a shareholder who provides substantial services must generally receive reasonable compensation through payroll before receiving non-wage distributions.

S corporation treatment can add:

• Payroll expenses
• Employment-tax filings
• A separate annual business return
• Reasonable-compensation analysis
• Ownership restrictions
• Stock-class restrictions
• Higher accounting costs

An S corporation election should be based on projected profit, payroll expenses, owner involvement and state tax consequences, not on the assumption that it always lowers tax.

Critical Federal Election Deadlines

Some startup decisions involve strict federal deadlines.

Election or Filing	General Timing	Purpose
Section 83(b) election	No later than 30 days after restricted property is transferred	May change when founder equity is taxed
Form 2553	Generally within two months and 15 days after the effective tax year begins	Elects S corporation status
Form 8832	Effective date is generally limited to 75 days before or 12 months after filing	Changes federal entity classification
Form 8822-B	Generally within 60 days after a responsible-party change	Updates IRS business information

The IRS provides Form 15620 for Section 83(b) elections. The election generally must be filed no later than 30 days after restricted property is transferred.

Form 2553 generally must be filed within two months and 15 days after the beginning of the tax year for which the S corporation election will apply.

Questions to Ask Before Choosing

Consider:

• What liabilities could the company face?
• Will there be one owner or several?
• Will owners contribute different amounts?
• Will profits be distributed or reinvested?
• Will the owners actively work in the business?
• Will the company raise outside capital?
• Will it issue employee equity?
• Will it operate in multiple states?
• What annual state fees apply?
• What is the likely exit strategy?

The best structure is the one that fits the entire legal, tax and growth plan, not merely the one with the lowest formation fee.

2. Register the Business Correctly

After choosing a structure, the company must complete the required registrations.

The process depends on:

• The state of formation
• The operating location
• The entity type
• The business name
• The industry
• Whether the company operates in additional states

Most LLCs and corporations are formed by filing articles of organization or incorporation with a secretary of state or comparable agency.

Common Registration Requirements

A company may need to:

• File formation documents.
• Appoint a registered agent.
• Pay a state filing fee.
• File an initial information statement.
• Register a DBA or assumed name.
• Obtain city or county registration.
• Register for state taxes.
• Qualify in additional states.
• Submit annual or biennial reports.
• Pay franchise or privilege taxes.

Registration requirements depend on the entity and every jurisdiction in which it conducts business.

Registered Agent

Most LLCs and corporations must maintain a registered agent in every state where they are registered.

The agent receives documents such as:

• Lawsuit papers
• State notices
• Compliance correspondence
• Certain tax communications

An unreliable address or expired registered-agent service can result in missed legal notices, administrative penalties or loss of good standing.

DBA or Assumed Name

A “doing business as” name allows a business to operate under a name different from its legal entity name.

For example, North Harbor Ventures LLC might operate a café as North Harbor Coffee.

A DBA does not normally:

• Create a new legal entity.
• Provide liability protection.
• Change federal tax treatment.
• Create nationwide trademark rights.

DBA requirements vary by state, county and municipality.

Foreign Qualification

A company formed in one state may need to register as a foreign entity in another state.

Activities that can trigger a review include:

• Opening an office
• Hiring an employee
• Operating a store
• Maintaining a warehouse
• Owning property
• Repeatedly providing local services

In this context, “foreign” usually means formed in another U.S. state.

Foreign qualification can require additional registered agents, annual reports, state fees and tax filings.

Should Every Startup Form in Delaware?

Delaware is commonly used by venture-backed corporations because of its developed corporate law and specialized Court of Chancery.

However, forming in Delaware does not automatically reduce taxes or paperwork.

A business operating in another state may still need to:

• Register in its operating state.
• Pay fees in two states.
• Maintain two registered agents.
• File reports in both jurisdictions.
• Pay Delaware franchise tax.

A local, owner-operated business with no institutional investment plan may find its operating state more practical.

Beneficial Ownership Reporting in 2026

Many older business-formation guides state that every domestic LLC and corporation must file a beneficial ownership information report with FinCEN.

That is no longer the current federal rule.

FinCEN’s March 2025 interim final rule exempts entities created in the United States and their beneficial owners from federal BOI reporting. Certain entities formed under foreign law and registered to conduct business in the United States may remain subject to reporting.

Because this requirement changed significantly, founders should verify current FinCEN guidance instead of relying on an older checklist.

Registration Checklist

Confirm that:

• The state accepted the formation filing.
• The legal name is consistent across all documents.
• The registered agent is active.
• Required DBAs are registered.
• Local registrations are complete.
• State tax accounts are open.
• Foreign qualification has been considered.
• Annual-report deadlines are recorded.
• Ownership records match the formation documents.

3. Document Ownership and Founder Relationships

Written ownership agreements are essential even when founders are friends, relatives or former colleagues.

Disputes often arise after the company begins earning money, raises capital, needs additional funding or experiences disagreement over strategy and workload.

An operating agreement, shareholders’ agreement, partnership agreement or founder agreement should clearly define the owners’ rights and responsibilities.

Essential Ownership Questions

Issue	Question to Resolve
Ownership	What percentage does each founder own?
Contributions	Who contributes cash, property, intellectual property or services?
Vesting	Does ownership vest over time?
Management	Who controls daily operations?
Voting	Which decisions require majority or unanimous approval?
Compensation	Will founders receive salaries, draws or distributions?
Intellectual property	Who owns code, designs, inventions and customer information?
Departure	What happens if a founder leaves?
Death or disability	Can the company or remaining founders buy the interest?
Transfers	Can a founder sell ownership to an outsider?
Disputes	Will disputes use litigation, mediation or arbitration?
Closure	How will liabilities and remaining assets be handled?

Founder Vesting

Without vesting, a founder may leave shortly after launch and retain the entire ownership interest.

A vesting arrangement can allow the company to repurchase or cancel unvested equity when a founder leaves early.

The agreement should define:

• The vesting commencement date
• The vesting period
• Any initial cliff
• Repurchase rights
• Treatment following termination
• Acceleration following a sale or qualifying termination
• Treatment following death or disability

Restricted Stock and Section 83(b)

A founder receiving stock subject to vesting should immediately determine whether a Section 83(b) election is appropriate.

The election may allow the founder to recognize income based on the stock’s value when transferred rather than as restrictions lapse. Because the filing deadline is generally 30 days, this decision cannot safely be postponed.

The founder should retain:

• A copy of the election
• Proof of timely filing
• Stock-purchase documents
• Board approval
• Evidence of payment
• Valuation support
• The capitalization table

An election is not always beneficial. If the stock is forfeited or decreases in value, the founder may not recover all related tax costs.

Founder Contributions and Loans

Transfers between founders and the company should be classified accurately as:

• Capital contributions
• Stock purchases
• Member contributions
• Founder loans
• Expense reimbursements
• Distributions
• Loan repayments

A founder loan should normally have a promissory note, repayment terms and an appropriate interest arrangement.

Intellectual-Property Assignments

The company should obtain written intellectual-property assignments from:

• Founders
• Employees
• Contractors
• Developers
• Designers
• Photographers
• Marketing agencies

Paying someone to create work does not always mean the company automatically owns every copyright, invention, design, source file or underlying tool.

The agreement should address:

• Final deliverables
• Drafts and source files
• Pre-existing materials
• Open-source software
• Confidential information
• Modification rights
• Commercialization rights
• Rights retained by the creator

Stock Options and 409A Valuation

A private company granting stock options generally needs a reasonable method for determining the fair market value of its common stock.

A company commonly reviews or updates its valuation when it:

• Begins granting options.
• Completes a financing round.
• Issues preferred stock.
• Experiences significant growth.
• Receives an acquisition offer.
• Reaches another major company milestone.

An outdated or unsupported valuation can create tax issues for the company and option recipients.

Qualified Small Business Stock

Founders and early investors in an eligible C corporation should consider qualified small business stock treatment under Section 1202 when shares are issued.

For qualifying stock acquired after July 4, 2025, the per-issuer excluded-gain limitation increased to $15 million, subject to the alternative basis limitation and other detailed requirements. Qualifying stock held for at least five years may be eligible for exclusion of up to 100% of the gain.

QSBS treatment depends on rules involving:

• Original issuance
• C corporation status
• Gross assets
• Active business operations
• Holding period
• Share redemptions
• The corporation’s industry

The company should preserve stock-purchase documents, issuance dates, capitalization tables, asset records, board approvals and evidence of qualifying business activities.

Raising Money From Investors

Selling stock, LLC interests, convertible notes or SAFEs can trigger federal and state securities laws.

Calling an investment informal, early-stage or limited to friends does not eliminate those obligations.

The company may need:

• Board and shareholder approval
• A federal securities exemption
• State notice filings
• Investor questionnaires
• Subscription agreements
• Risk disclosures
• Financial statements
• Updated ownership records

SAFEs and Convertible Notes

A SAFE or convertible note may delay a formal valuation discussion, but it does not eliminate dilution or legal risk.

The documents should address:

• Conversion events
• Valuation caps
• Discounts
• Interest
• Maturity
• Qualified financing thresholds
• Sale treatment
• Dissolution treatment
• Amendment rights
• Most-favored-nation provisions

Founders should model the fully diluted capitalization table before issuing several financing instruments.

Regulation Crowdfunding

An investment crowdfunding campaign differs from a rewards campaign that simply sells products or provides non-investment benefits.

Regulation Crowdfunding offerings generally must use an SEC-registered intermediary. An issuer that sells securities through Regulation Crowdfunding generally must file Form C-AR within 120 days after the end of its fiscal year until it qualifies to end annual reporting.

Financial forecasts, advertising statements and risk disclosures should be accurate, consistent and supportable.

4. Protect the Business Name and Intellectual Property

Approval of a company name by a state does not necessarily mean the name is safe to use as a brand.

Four separate issues should be considered:

1. Legal entity name
2. DBA or assumed name
3. Domain and social-media names
4. Trademark rights

Entity Registration Is Not Trademark Clearance

A state filing office normally checks whether a proposed entity name is distinguishable within its own records. It does not perform a complete trademark infringement analysis.

A company can therefore form an LLC successfully and later receive a legal claim from an earlier trademark owner.

The USPTO explains that registering a business or domain name does not, by itself, create federal trademark rights. A registered domain may still infringe another party’s trademark.

Search Before Launch

A preliminary trademark-clearance search should examine:

• USPTO records
• State trademark databases
• State business records
• Search-engine results
• Industry directories
• App stores
• Domain names
• Social-media platforms
• Similar spellings
• Similar pronunciations

The search should cover related products and services, not only identical names.

Main Types of Intellectual Property

Type	Common Asset	Basic Protection
Trademark	Name, logo or slogan	Commercial use and federal or state registration
Copyright	Articles, photographs, videos, software and designs	Automatic rights with additional registration benefits
Patent	Inventions and certain designs	Application and grant
Trade secret	Methods, customer data, formulas and strategies	Reasonable secrecy measures
Contract right	Licensed or commissioned work	Written agreement

Trademarks, patents and copyrights protect different categories of intellectual property.

Trade-Secret Protection

A company cannot reasonably claim information is secret if it takes no practical steps to protect it.

Possible safeguards include:

• Confidentiality agreements
• Limited employee access
• Password protection
• Secure storage
• Vendor restrictions
• Employee training
• Device-management procedures
• Rapid account termination
• Confidentiality labels

Potential trade secrets include customer lists, formulas, pricing models, manufacturing methods, product road maps and proprietary algorithms.

Avoid Unlicensed Content

Businesses frequently create legal exposure by copying:

• Images found online
• Music from social platforms
• Competitor articles
• Software code
• Fonts
• Product photographs
• Videos
• Customer testimonials

Use original material, properly licensed content, verified public-domain resources or assets covered by a suitable written agreement.

5. Obtain Licenses, Permits, Zoning and Accessibility Approval

Forming an entity does not automatically authorize the company to conduct every type of business.

Most companies need some combination of federal, state or local licenses. Exact requirements depend on the company’s activities and location.

Federal Regulation

Federal licensing or registration may apply to activities involving:

• Alcohol
• Aviation
• Broadcasting
• Commercial fishing
• Agriculture
• Transportation
• Interstate trucking
• Mining
• Wildlife
• Firearms or explosives
• Certain financial services

A federal license does not necessarily replace state or local approval.

State and Local Requirements

Possible requirements include:

• General business license
• Seller’s permit
• Sales-tax registration
• Food-service permit
• Health department approval
• Professional license
• Contractor license
• Childcare license
• Environmental permit
• Building permit
• Fire inspection
• Sign permit
• Certificate of occupancy
• Home-occupation permit

Zoning

Before signing a long-term lease, confirm that the intended use is permitted.

A property previously used for retail may not automatically be approved for:

• A restaurant
• A medical office
• Childcare
• Manufacturing
• Automotive repair
• Food production
• Entertainment

Review:

• Permitted use
• Parking
• Sign restrictions
• Occupancy limits
• Fire requirements
• Accessibility
• Waste rules
• Delivery restrictions
• Operating hours

Where possible, a lease should protect the tenant if required permits or approvals cannot be obtained.

Home-Based Businesses

A home-based business may still face:

• Zoning restrictions
• Home-occupation permits
• Lease restrictions
• Homeowners’ association rules
• Visitor limits
• Sign restrictions
• Inventory limits
• Insurance exclusions

A home-office tax deduction does not override zoning, rental or homeowners’ association restrictions.

Accessibility Requirements

Businesses open to the public may have obligations under Title III of the Americans with Disabilities Act.

Depending on the operation, compliance may involve:

• Accessible entrances and routes
• Appropriate service counters
• Effective communication
• Reasonable policy modifications
• Captions or other communication aids
• Accessible online forms
• Keyboard-compatible navigation
• Alternative text for meaningful images
• Checkout processes that work with assistive technology

The Department of Justice explains that Title III applies to businesses open to the public and requires equal access to their goods, services and facilities. Its web guidance also states that online services offered by covered businesses should be accessible to people with disabilities.

Licensing and Location Checklist

Before opening:

• Identify applicable federal regulators.
• Check state licensing agencies.
• Contact city and county authorities.
• Confirm zoning before signing a long lease.
• Obtain a certificate of occupancy where required.
• Review professional licensing rules.
• Evaluate physical and online accessibility.
• Record every renewal date.

6. Get Tax IDs and Separate Business Finances

After formation, the company should establish a separate financial and tax identity.

Employer Identification Number

An Employer Identification Number is a federal taxpayer identification number issued by the IRS.

A business may need an EIN to:

• Hire employees
• File entity returns
• Open a business bank account
• Establish payroll
• Make tax elections
• Apply for licenses
• Work with major vendors

Eligible businesses can apply directly through the IRS. The IRS does not charge a fee, and an approved online application can produce the EIN immediately.

Founders should be cautious of commercial websites that appear to be government agencies or charge unnecessary processing fees.

State Tax Accounts

Depending on the company, additional registrations may include:

• State income tax
• Sales and use tax
• Employer withholding
• Unemployment insurance
• Franchise tax
• Gross receipts tax
• Excise tax
• Local occupational tax

Separate Business Bank Account

The company should use a dedicated business account for:

• Customer payments
• Owner contributions
• Loans
• Vendor payments
• Payroll
• Taxes
• Distributions
• Reimbursements

Paying personal bills from the company account creates bookkeeping problems and may weaken the distinction between the company and its owners.

Categorize Owner Transactions

Every transaction between an owner and the company should be identified correctly.

Possible categories include:

• Capital contribution
• Share purchase
• Member draw
• Shareholder distribution
• Salary
• Expense reimbursement
• Owner loan
• Loan repayment

A loan is not sales revenue, and an owner contribution is not taxable customer income.

Accountable Reimbursement Plan

A corporation or S corporation may use a written accountable plan to reimburse qualifying employee business expenses.

Generally, the expense should:

• Have a business connection.
• Be properly substantiated.
• Be reported within a reasonable period.
• Include repayment of any excess advance.

Potential reimbursable costs include:

• Business mileage
• Travel
• Lodging
• Supplies
• Software
• Professional subscriptions
• Business telephone costs
• Certain documented home-office costs

Reimbursements that do not satisfy the applicable requirements may need to be treated as taxable wages.

Set Up Bookkeeping Before Launch

Track:

• Sales
• Refunds
• Cost of goods sold
• Operating expenses
• Payroll
• Sales tax collected
• Owner contributions
• Loans
• Fixed assets
• Depreciation
• Accounts receivable
• Accounts payable

Store receipts, invoices, contracts, bank statements and tax documents in an organized system.

Cash Versus Accrual Accounting

Under cash-basis accounting, income and expenses are generally recorded when money is received or paid.

Under accrual accounting, income and expenses are generally recorded when earned or incurred.

Inventory, revenue, entity type, reporting needs and industry practices may affect which method is appropriate.

7. Understand Federal Business Taxes

Federal tax responsibilities depend on the company’s structure and activities.

Major categories include:

• Income tax
• Estimated tax
• Self-employment tax
• Employment tax
• Excise tax
• Information reporting

Common Federal Returns

Business	Common Federal Filing
Sole proprietorship	Form 1040 with Schedule C
Default single-member LLC	Usually Form 1040 with Schedule C
Partnership or default multi-member LLC	Form 1065 and Schedules K-1
S corporation	Form 1120-S and Schedules K-1
C corporation	Form 1120
Employer	Forms 941 or 944, Form 940 and Forms W-2
Business paying contractors	Forms 1099 when applicable

Pass-Through Taxation

Sole proprietors generally report business profit on their individual returns.

Partnerships and S corporations generally pass tax items through to their owners. An owner may owe tax on allocated income even when the company retains the related cash.

A C corporation generally pays its own federal income tax.

Qualified Business Income Deduction

Eligible owners of sole proprietorships, partnerships and S corporations may qualify for the Section 199A qualified business income deduction.

The deduction can equal up to 20% of qualifying business income, subject to taxable-income, business-type, wage and property limitations.

Beginning in 2026, current federal law also provides a possible minimum deduction of $400 for a taxpayer with at least $1,000 of net qualified business income from active businesses in which the taxpayer materially participates. C corporation income does not qualify for the owner-level deduction.

Self-Employment and Payroll Taxes

Self-employment tax generally funds Social Security and Medicare for self-employed individuals.

For 2026:

• The Social Security rate is 6.2% for employees and 6.2% for employers.
• The Social Security wage base is $184,500.
• The Medicare rate is generally 1.45% for each side.
• Medicare tax does not have the same wage-base limit.

Additional Medicare tax may apply above the relevant statutory income threshold.

Estimated Taxes

Owners who do not have sufficient tax withheld may need to make estimated payments during the year.

Individuals generally evaluate estimated-payment obligations when they expect to owe at least $1,000 after withholding and credits. Safe-harbor and annualization rules can affect the required amount.

A practical system is to transfer part of each customer payment into a separate tax account rather than waiting until the annual return is due.

Employer Tax Duties

An employer may need to:

• Withhold federal income tax.
• Withhold employee Social Security and Medicare.
• Pay the employer share of Social Security and Medicare.
• Deposit taxes on schedule.
• File payroll returns.
• Pay federal unemployment tax.
• Issue Forms W-2.
• Maintain payroll records.

Amounts withheld from employees are not ordinary company funds and should never be used casually to cover operating expenses.

2026 Contractor Reporting Threshold

For qualifying payments made in 2026, the general information-reporting threshold for certain Forms 1099-NEC and 1099-MISC payments increased from $600 to $2,000. Special rules and exceptions still apply.

Obtain Form W-9 before paying a contractor so the company has the correct legal name and taxpayer identification number.

Startup and Organizational Costs

Costs incurred before active business operations begin may receive different tax treatment from ordinary operating expenses.

A business may generally elect to deduct up to $5,000 of qualifying startup expenses and up to $5,000 of qualifying organizational expenses, subject to reduction rules. Remaining qualifying costs are generally recovered over time.

Potential startup expenses include:

• Market research
• Pre-opening advertising
• Employee training
• Supplier research
• Consulting
• Pre-opening travel

Equipment, inventory, acquisition costs and other capital expenditures may follow different rules.

Section 179 Deduction

Section 179 may allow a business to deduct the cost of qualifying property more quickly.

For tax years beginning in 2026:

• The maximum Section 179 deduction is $2,560,000.
• The phaseout begins when qualifying property placed in service exceeds $4,090,000.
• A separate $32,000 limit applies to certain sport utility vehicles.

Eligibility, business use and taxable income affect the available deduction.

Bonus Depreciation

Current federal law generally provides 100% additional first-year depreciation for certain qualifying property acquired after January 19, 2025, when the applicable placed-in-service requirements are satisfied.

Section 179 and bonus depreciation are not interchangeable. State tax treatment may also differ from federal treatment.

A deduction should not be the only reason to purchase equipment that the company does not need.

Research and Experimental Expenses

Businesses developing software, products, manufacturing processes or technology should separately track research expenses.

Current federal rules generally allow qualifying domestic research and experimental costs to be deducted currently beginning in 2025. Taxpayers may instead elect to capitalize and amortize qualifying domestic expenditures over at least 60 months. Foreign research costs generally continue to be amortized over 15 years.

Records should identify:

• The research project
• Technical uncertainty
• Employee time
• Contractor work
• Supplies
• Testing
• Research location

Research Payroll Tax Credit

A qualifying small business may elect to apply up to $500,000 of research credit against eligible employer payroll-tax liabilities.

This can be valuable for an early-stage company with research activity and employees but limited taxable income.

Eligibility depends on detailed gross-receipts, research and filing requirements.

Home-Office Deduction

A qualifying self-employed owner may deduct certain expenses related to business use of a home.

The space generally must be used regularly and exclusively for business, subject to limited exceptions.

A tax deduction does not make the activity lawful under zoning, lease or homeowners’ association rules.

Common Federal Tax Mistakes

Avoid:

• Waiting until year-end to estimate tax.
• Deducting personal expenses as business expenses.
• Paying owners incorrectly.
• Missing tax-election deadlines.
• Taking S corporation distributions without reasonable compensation.
• Treating contributions as customer revenue.
• Treating loan proceeds as sales.
• Ignoring payment-processor reports.
• Deducting equipment incorrectly.
• Failing to retain supporting records.

8. Prepare for State and Local Taxes

A company can comply with IRS rules and still owe substantial state or local taxes.

Possible obligations include:

• State income tax
• Franchise tax
• Gross receipts tax
• Sales and use tax
• Employer withholding
• Unemployment tax
• Local income tax
• Business privilege tax
• Personal property tax
• Occupational tax
• Excise tax

Sales and Use Tax

A business selling taxable products or services may need to:

• Obtain a sales-tax permit.
• Collect tax from customers.
• File periodic returns.
• File zero returns when required.
• Preserve exemption certificates.
• Track taxable and exempt sales.
• Pay use tax on untaxed purchases.

States differ significantly in how they treat:

• Software
• Digital products
• Subscriptions
• Professional services
• Shipping charges
• Food
• Installation
• Repairs

Economic Nexus

A company may create sales-tax obligations without maintaining a traditional office in a state.

Potential nexus factors include:

• Sales volume
• Transaction count
• Inventory stored by a third party
• Marketplace activity
• Employees
• Contractors
• Installation work
• Trade-show attendance

Online businesses should track revenue and transactions by state from the beginning.

Marketplace Sales

A marketplace may collect sales tax on transactions conducted through its platform, but that does not necessarily eliminate:

• Business registration requirements
• Tax on direct website sales
• Income-tax nexus
• Franchise tax
• Local taxes
• Recordkeeping duties

Franchise and Gross Receipts Taxes

Some states impose charges that are not based entirely on business profit.

A company may owe:

• Minimum franchise tax
• Annual LLC fees
• Gross receipts tax
• Capital-stock tax
• Privilege tax
• Annual report fees

A business can owe these amounts even when it reports an operating loss.

Remote Employees

Hiring an employee in another state may create:

• Payroll registration
• Income-tax withholding
• Unemployment insurance
• Workers’ compensation
• Paid-leave obligations
• State labor-law coverage
• Foreign qualification
• Income or franchise-tax nexus

Multistate Review

Regularly review:

• Employee locations
• Contractor locations
• Inventory
• Warehouses
• Offices
• Sales by state
• Trade-show activities
• Installation work
• Property ownership
• Marketplace storage

The test for state entity registration may differ from the test for tax nexus.

9. Follow Employment and Worker-Classification Laws

Hiring workers creates significant legal and tax responsibilities.

Before the first employee begins work, establish:

• Payroll
• Tax withholding
• Workers’ compensation
• Unemployment insurance
• Employment eligibility procedures
• Timekeeping
• Wage and overtime rules
• Required workplace notices
• New-hire reporting
• Anti-discrimination procedures

Employee or Independent Contractor?

A contract cannot transform an employee into an independent contractor when the actual working relationship indicates employment.

Federal tax analysis considers behavioral control, financial control and the nature of the relationship. Wage law, unemployment law, workers’ compensation law and state law may apply different tests.

On February 26, 2026, the Department of Labor proposed revising the federal independent-contractor analysis and rescinding the 2024 rule. The proposal was not a final replacement as of July 21, 2026, and state standards may be stricter.

Misclassification can lead to:

• Payroll-tax assessments
• Overtime claims
• Minimum-wage claims
• Benefits disputes
• Unemployment assessments
• Workers’ compensation liability
• Penalties
• Interest

Employee Onboarding

A basic onboarding file may include:

• Offer letter
• Employment agreement
• Form W-4
• Form I-9
• State withholding form
• Direct-deposit authorization
• Confidentiality agreement
• Intellectual-property assignment
• Policy acknowledgments
• Emergency contact information

Wage-and-Hour Compliance

Review:

• Federal, state and local minimum wages
• Overtime
• Exempt status
• Meal and rest periods
• Timekeeping
• Pay frequency
• Final-pay requirements
• Paid sick leave
• Scheduling laws
• Payroll records

Paying an employee a salary does not automatically make that person exempt from overtime.

Anti-Discrimination and Workplace Policies

Employment decisions should use legitimate job-related criteria.

Review practices involving:

• Job advertising
• Recruiting
• Interviews
• Background checks
• Compensation
• Promotions
• Leave
• Disability and religious accommodations
• Discipline
• Termination
• Harassment complaints

State and local employment laws may cover businesses that are too small to be covered by a particular federal statute.

Foreign Founders and Work Authorization

A foreign national may own part of a U.S. company without automatically being authorized to work for it while physically present in the United States.

Potential immigration pathways depend on nationality, investment, ownership, company structure, job duties and qualifications. USCIS lists several entrepreneur pathways, including treaty-investor and parole options, but each has specific eligibility requirements.

Immigration advice should be obtained before a foreign founder begins productive work in the United States.

Employment Checklist

Before hiring:

• Confirm worker classification.
• Register payroll accounts.
• Obtain workers’ compensation coverage where required.
• Establish timekeeping.
• Prepare offer and onboarding documents.
• Complete tax and employment-eligibility forms.
• Report the new hire.
• Display required notices.
• Establish complaint procedures.
• Protect confidential information.
• Schedule payroll filings and deposits.

10. Use Contracts and Protect Customer Data

Written agreements reduce uncertainty, preserve evidence and allocate risk.

A contract should explain what each party must do, when performance is due and what happens if the relationship ends.

Customer Contract Terms

A customer agreement may cover:

• Scope of work
• Deliverables
• Pricing
• Deposits
• Payment deadlines
• Taxes
• Late fees
• Change requests
• Customer responsibilities
• Intellectual-property ownership
• Confidentiality
• Warranties
• Disclaimers
• Liability limits
• Indemnification
• Cancellation
• Refunds
• Dispute resolution
• Governing law
• Electronic signatures

The written contract should match the company’s actual sales and customer-service practices.

Vendor Agreements

A vendor agreement may address:

• Specifications
• Delivery
• Pricing
• Quality standards
• Confidentiality
• Personal-data access
• Intellectual property
• Insurance
• Indemnification
• Termination
• Transition support

The company, not an outside agency should control the primary administrative access to:

• Domain registration
• Hosting
• Analytics
• Advertising accounts
• Social profiles
• Payment processors
• Code repositories
• Cloud storage

Consumer Protection and Advertising

Marketing statements should be truthful, supportable and not misleading.

Extra caution is needed with claims involving:

• Earnings
• Health benefits
• Environmental benefits
• Product performance
• Artificial intelligence
• Testimonials
• Discounts
• Guarantees
• Scarcity
• “Free” offers

Commercial Email

Commercial email subject to the CAN-SPAM Act should use accurate sender information, nondeceptive subject lines, a valid postal address and a functioning opt-out process.

Hiring a marketing company does not necessarily remove the advertiser’s compliance responsibility.

Privacy Policy

A privacy policy should accurately explain:

• What information is collected
• Why it is collected
• How it is used
• Who receives it
• How long it is retained
• What choices customers have
• How applicable rights may be exercised
• How to contact the company

Do not copy another company’s privacy policy. It may describe practices your company does not follow or omit obligations that apply to your business.

State Privacy Laws

Depending on revenue, industry, customer location and data volume, a company may be affected by state privacy statutes.

Possible obligations include:

• Privacy notices
• Access rights
• Correction rights
• Deletion rights
• Opt-outs
• Sensitive-data consent
• Data-processing agreements
• Security safeguards
• Retention limits

Children’s, health, educational and financial information may be subject to specialized laws.

Data Security

A practical security program may include:

• Multifactor authentication
• Unique employee accounts
• Password management
• Prompt software updates
• Device encryption
• Secure backups
• Limited administrator access
• Vendor reviews
• Phishing training
• Immediate access termination
• Data-retention rules
• Incident-response procedures

The FTC recommends that businesses identify the personal information they hold, keep only what they need, protect retained information and prepare in advance for security incidents.

Data-Breach Response

A cybersecurity plan should address what happens after a suspected breach, not only how to prevent one.

A response plan should identify who will:

• Secure affected systems.
• Preserve evidence.
• Engage forensic specialists.
• Contact legal counsel.
• Notify the cyber insurer.
• Determine what information was affected.
• Coordinate customer communications.
• Notify law enforcement or regulators where required.
• Document the investigation and remediation.

The FTC advises companies to mobilize a breach-response team quickly, stop additional data loss, preserve evidence and determine applicable notification responsibilities.

Notification deadlines and required contents can depend on the affected individuals’ locations, the information involved and the industry.

11. Purchase Appropriate Business Insurance

A legal entity is not a replacement for insurance.

A lawsuit, cyberattack, fire, theft, employee injury or product claim can exhaust company assets even when the owners are not personally liable.

Common Coverage

Insurance	Main Purpose
General liability	Third-party injury, property damage and certain advertising claims
Professional liability	Errors, omissions and professional negligence
Product liability	Injury or damage caused by products
Commercial property	Equipment, buildings and inventory
Business interruption	Lost income after certain covered events
Workers’ compensation	Employee work-related injuries
Commercial auto	Business vehicle risks
Cyber insurance	Data breaches and cyber incidents
Employment practices liability	Certain workplace claims
Directors and officers	Claims involving management decisions
Key-person insurance	Financial effect of losing an essential person
Home-business endorsement	Business risks excluded from a standard home policy

Review the Policy, Not Just Its Name

Evaluate:

• Coverage limits
• Deductibles
• Exclusions
• Geographic territory
• Claims-made requirements
• Retroactive dates
• Notice deadlines
• Defense costs
• Contractor coverage
• Cybersecurity conditions

General liability may not cover professional errors, employment disputes, cyber incidents or damage to the company’s property.

Contractual Insurance Requirements

A landlord, lender or customer may require:

• Minimum coverage limits
• Additional-insured status
• Waiver of subrogation
• Primary coverage
• Certificates of insurance
• Notice of cancellation

Confirm that the policy satisfies the contract before signing it.

12. Maintain Records and Ongoing Compliance

Business formation is only the beginning.

A company must maintain good standing and complete recurring legal, tax and licensing obligations. Annual requirements depend on the entity and state.

Entity Compliance

A company may need to maintain:

• A registered agent
• Annual or biennial reports
• Franchise-tax payments
• Business licenses
• Professional licenses
• DBA renewals
• Foreign registrations
• Corporate minutes
• Written consents
• Ownership ledgers
• Operating agreements
• Bylaws
• Stock records
• Current addresses

Legal and Tax Records

Preserve documents supporting:

• Revenue
• Expenses
• Credits
• Deductions
• Payroll
• Ownership
• Equity grants
• Securities offerings
• Tax elections
• Property basis
• Depreciation
• Loans
• Insurance
• Contracts

Important records may include:

• Invoices
• Receipts
• Bank statements
• Payroll files
• Mileage logs
• Loan documents
• Stock-purchase agreements
• Section 83(b) elections
• Valuation reports
• Board approvals
• Tax returns
• Securities filings
• License records

Compliance Calendar

Frequency	Possible Obligations
Every payroll	Wage calculations, withholding and payroll records
Monthly	Sales tax, payroll deposits or local taxes
Quarterly	Estimated tax and payroll returns
Annually	Income tax, W-2s, 1099s, licenses and entity reports
Biennially	State reports in jurisdictions using two-year cycles
Event-based	New hires, equity grants, address changes and ownership changes

Review Compliance When the Business Changes

Schedule a legal and tax review when the company:

• Adds an owner.
• Raises capital.
• Hires in another state.
• Opens a new location.
• Launches a new product.
• Collects new categories of personal information.
• Enters a regulated industry.
• Expands internationally.
• Changes tax treatment.
• Acquires another company.
• Sells major assets.

Sale or Ownership Transfer

A sale, merger or ownership change may require review of:

• Transfer restrictions
• Investor approval
• Lender consent
• Personal guarantees
• Lease assignment
• Intellectual-property transfer
• Employee obligations
• Customer contracts
• Tax consequences
• License transfers
• EIN requirements

An asset sale and a sale of stock or membership interests can produce very different legal and tax results.

The IRS states that a new EIN may be required when a business changes its ownership or legal structure, although a simple name or address change generally does not require one.

Closing the Business

Stopping operations does not automatically dissolve an LLC or corporation.

An inactive entity may continue to incur:

• Annual reports
• Franchise taxes
• Registered-agent fees
• License renewals
• Penalties

Formal closure may require:

• Owner approval
• Articles of dissolution
• Withdrawal from other states
• Final tax returns
• Final payroll deposits
• Final Forms W-2 and 1099
• Creditor notices
• Contract termination
• License cancellation
• Distribution of remaining assets
• Record retention

Common Legal and Tax Mistakes

Forming in Delaware without a clear reason	Duplicate reports and fees	Compare Delaware with the operating state
Operating without ownership agreements	Founder disputes	Use written governance documents
Missing a tax-election deadline	Lost tax treatment	Record deadlines when equity or the entity is created
Mixing personal and company funds	Weak records and entity separation	Maintain dedicated accounts
Ignoring sales tax	Back tax, penalties and interest	Track products, customer states and nexus
Classifying every worker as a contractor	Payroll and wage claims	Apply current federal and state tests
Accepting investment informally	Securities-law exposure	Use proper approvals, documents and exemptions
Paying an S corporation owner only through distributions	Employment-tax assessments	Pay reasonable compensation
Copying online legal policies	Inaccurate representations	Draft policies around actual practices
Missing annual reports	Loss of good standing	Maintain a compliance calendar
Assuming an LLC prevents every loss	Uninsured company exposure	Combine entity protection, contracts and insurance

Conclusion: legal and tax issues when starting a business

Understanding the legal and tax issues when starting a business is essential for protecting founders, preserving company assets and avoiding costly corrections.

The most important decisions, including entity structure, ownership, tax classification, intellectual property, licenses, contracts and worker status should be addressed before the company begins significant operations.

A successful launch requires more than filing formation documents. The business must maintain separate finances, collect and remit applicable taxes, protect intellectual property, follow employment laws, secure customer information, purchase insurance and complete recurring filings.

Founders do not need to become experts in every area of law and taxation. They do need to identify risks early, maintain reliable records and seek professional advice before making decisions that may be difficult to reverse.

The strongest companies treat legal and tax compliance as part of their operating system rather than an administrative task to postpone. With a sound foundation, owners can devote more time to developing products, serving customers and building sustainable growth.
