How to Start a Small Business in the U.S. (Legal Guide)
Starting a small business in the United States offers incredible opportunity—but also comes with legal responsibilities. Whether you're launching a side hustle, an online store, or a full-scale company, following the proper steps from day one sets you up for long-term success.
This guide walks you through the key legal, regulatory, and administrative steps to start a business in the U.S., helping you launch with confidence and stay compliant.
Why Legal Compliance Matters from Day One
Skipping essential legal steps can lead to:
- Delays in opening
- IRS penalties
- Personal liability risks
- Trouble securing funding
Starting right means protecting your business, your assets, and your future growth potential.
Step 1: Choose a Business Structure
Your business structure affects everything from taxes to liability to funding. Common U.S. structures include:
- Sole Proprietorship – Simple, but offers no personal liability protection
- Limited Liability Company (LLC) – Flexible and protects your personal assets
- Corporation (C or S Corp) – Ideal for companies seeking outside investment
- Partnership – For two or more owners sharing profits and liabilities
Choosing the right structure is a foundational legal decision. Consult an attorney or advisor if you're unsure.
Step 2: Register Your Business
Once you've chosen a structure, you'll need to register:
- LLCs and Corporations: Register with the Secretary of State in your chosen state
- Sole Proprietorships and Partnerships: May need a DBA (“Doing Business As”) registration
- Obtain an EIN: Apply for a free Employer Identification Number from the IRS
Tip: Most banks require an EIN to open a business bank account.
Step 3: Apply for Licenses & Permits
Your business may need one or more of the following:
- General business license
- Industry-specific permits (e.g., food, construction, childcare)
- Zoning or home occupation permit
- Seller’s permit or resale certificate (for product-based businesses)
Check requirements at the federal, state, and local levels.
Step 4: Understand Your Tax Obligations
Taxes vary depending on your location and structure. Common tax responsibilities include:
- Federal income tax (filed with the IRS)
- State and local income tax (where applicable)
- Sales tax collection
- Payroll tax (if hiring employees)
- Self-employment tax
Consulting a small business CPA can help you stay compliant and maximize deductions.
Step 5: Set Up Business Finances
To keep personal and business finances separate:
- Open a business checking account
- Set up accounting software or hire a bookkeeper
- Track income and expenses from the start
- Prepare for quarterly estimated tax payments
Step 6: Hire Employees (If Applicable)
Before you hire:
- Register with your state’s labor department
- Obtain workers’ compensation insurance
- Understand wage, hour, and anti-discrimination laws
- Verify employment eligibility (Form I-9 and E-Verify)
You’ll also need to issue W-2s and file payroll taxes.
Step 7: Stay Compliant Over Time
Compliance isn’t a one-time task. Ongoing responsibilities may include:
- Annual reports and business license renewals
- Keeping accurate financial records
- Renewing permits
- Staying up-to-date on local and industry-specific laws
