Step-by-step guide to the legal requirements for starting a business in any U.S. state.

Starting a Business: Legal Checklist

1. Choose Your Business Structure

The first decision is your business entity type. Each has different legal and tax implications:

  • Sole Proprietorship: Simplest form. You and the business are legally the same. Easy to start but you're personally liable for debts.
  • LLC (Limited Liability Company): Provides liability protection. Profits pass through to your personal tax return. Most popular for small businesses.
  • Corporation (C-Corp): Separate legal entity. Best for raising investment. Subject to double taxation.
  • S-Corporation: Corporation that elects pass-through taxation. Limited to 100 shareholders.
  • Partnership: Two or more owners. General partners have unlimited liability; limited partners do not.
  • 2. Register Your Business Name

  • Check availability with your state's Secretary of State
  • File a DBA ("Doing Business As") if using a name different from your legal name
  • Consider trademark registration for brand protection
  • 3. Get an EIN (Employer Identification Number)

  • Free from the IRS at irs.gov
  • Required for hiring employees, opening business bank accounts, and filing taxes
  • Apply online — you'll receive your EIN immediately
  • 4. Register with State and Local Government

  • File formation documents (Articles of Organization for LLC, Articles of Incorporation for corps)
  • Register for state tax accounts (sales tax, income tax withholding)
  • Obtain required business licenses and permits
  • 5. Comply with Employment Laws

    If hiring employees:

  • Register for workers' compensation insurance
  • Set up payroll tax withholding (federal, state, local)
  • Post required workplace notices (OSHA, FMLA, minimum wage)
  • Verify employment eligibility (I-9 forms)
  • Comply with anti-discrimination laws
  • 6. Protect Your Business

  • Get business insurance (general liability, professional liability)
  • Create an operating agreement (LLC) or bylaws (corporation)
  • Set up separate business bank accounts
  • Keep meticulous records
