From registering your business to obtaining the right permits, licenses, and tax obligations, legal compliance is a foundation you cannot ignore.
According to research from the Kauffman Foundation for Entrepreneurship, businesses that comply with legal requirements from the beginning are more likely to secure funding, build customer trust, and avoid costly penalties later on. While the process may seem complex, breaking it down into manageable steps can help you feel confident and prepared.
This guide explains the key U.S. business legal requirements, provides actionable steps, and answers common questions entrepreneurs have about starting a business in America.

Step-by-Step Legal Requirements for Starting a Business in the USA
1. Choose a Business Structure
The first and most important step is choosing the right legal entity for your business.
Common Business Structures in the U.S.:
| Structure | Description | Best For | Liability Protection | Taxation |
|---|---|---|---|---|
| Sole Proprietorship | Owned by one individual | Freelancers, small businesses | No personal liability protection | Personal tax return |
| Partnership | Owned by 2+ people | Small teams or family businesses | Shared liability | Pass-through taxation |
| LLC (Limited Liability Company) | Hybrid structure | Startups, small businesses | Protects personal assets | Flexible taxation |
| Corporation (C-Corp or S-Corp) | Separate legal entity | Large businesses, venture-backed startups | Strong liability protection | Corporate or pass-through taxation |
👉 Tip: Most small businesses in the U.S. start as LLCs because they offer liability protection and tax flexibility.
2. Register Your Business Name
A unique business name helps distinguish your brand.
- Check availability: Search the U.S. Patent and Trademark Office (USPTO) database.
- File a DBA (Doing Business As): If operating under a different name than your legal entity.
- Trademark your brand: To protect against infringement nationwide.
3. Obtain a Federal Employer Identification Number (EIN)
An EIN is like a Social Security Number for your business. You need it to:
- Open a business bank account.
- Hire employees legally.
- File federal and state taxes.
You can apply for an EIN free on the IRS website.
4. Register with State and Local Agencies
Business laws vary by state. You may need to:
- File Articles of Organization (for LLCs).
- File Articles of Incorporation (for corporations).
- Register with your state’s Secretary of State office.
👉 Example: In California, businesses must also comply with the California Franchise Tax Board, while in Delaware (a popular incorporation state), businesses pay annual franchise taxes.
5. Obtain Business Licenses and Permits
Depending on your industry, you may need federal, state, or local permits.
Examples:
- Restaurants: Health permits, liquor licenses.
- Construction companies: Contractor licenses.

- Financial services: Federal licensing from agencies like the SEC or FINRA.
👉 Pro Tip: Use the U.S. Small Business Administration (SBA) License and Permit Tool to identify requirements in your state.
6. Understand Federal and State Tax Obligations
Taxes are a major part of legal compliance.
- Federal Taxes (IRS): Income tax, self-employment tax, payroll tax.
- State Taxes: Vary by state; includes sales tax, franchise tax, and state income tax.
- Local Taxes: County and city taxes depending on location.
Example of State Tax Differences:
- Florida: No state income tax, but sales tax applies.
- California: High state income tax, complex regulations.
- Texas: No personal income tax, but franchise tax required.
7. Open a Business Bank Account
Separating personal and business finances protects your assets and simplifies accounting.
- Required by banks to have an EIN.
- Some banks may require an Operating Agreement (for LLCs).
8. Set Up Business Insurance
Insurance protects against lawsuits, accidents, and disasters.
Types of Business Insurance in the U.S.:
- General liability insurance – covers accidents and damages.

9. Understand Employment and Labor Laws
If you plan to hire employees, you must comply with:
- Fair Labor Standards Act (FLSA): Governs wages and overtime.
- Occupational Safety and Health Administration (OSHA): Workplace safety.

- State-specific laws: Such as California’s strict labor protections.
10. Protect Intellectual Property (IP)
If you develop unique products, services, or branding, protect your assets legally.
- Trademarks: Protect business names, logos, slogans.
- Copyrights: Protect creative works.
- Patents: Protect inventions and technologies.
👉 Example: Stanford University research highlights that strong intellectual property protections help startups secure venture capital more easily.
11. Draft Legal Contracts and Agreements
Contracts reduce risk and clarify responsibilities. Essential agreements include:

- Non-disclosure agreements (NDAs).
- Client service agreements.
