Business Licenses: Federal vs State vs Local — What You Actually Need
Most small business owners either do too little on licenses (and risk operating illegally) or too much (and spend money on permits they do not need). The requirements vary by state, city, county, and business type. Here is a framework for figuring out exactly what applies to you.

The Quick Answer
Most small businesses need at minimum a general business license from their city or county, and many need a state-level license depending on their industry. Federal licenses are required only for specific regulated industries. Start with your state's Secretary of State website and the SBA license and permit tool — both give you a starting point tailored to your state and business type.
Federal vs State vs Local: What Each Covers
Federal licenses: Required for heavily regulated industries — firearms, alcohol, agriculture, aviation, broadcasting, financial services, transportation. If you are in one of these industries, you know it. Most small businesses do not need a federal license.
State licenses: Many states require a general business license plus industry-specific licenses (contractor licenses, professional licenses for healthcare, legal, real estate, cosmetology). Required in most states if you sell products (sales tax permit) or hire employees (state employer registration).
Local licenses and permits: City or county business licenses are the most commonly overlooked. Many localities require a general business license just to operate. Zoning permits, home occupation permits, and signage permits may also apply.
Industries That Always Require Special Licenses
Healthcare: Physicians, dentists, therapists, and other medical professionals need state professional licenses. Facilities need additional permits. Construction and contracting: Most states require a contractor license to perform work above a threshold dollar value. Real estate: Agents and brokers require state licensing and ongoing continuing education. Food service: Health department permits, food handler certifications, and local fire inspections. Childcare: State licensing, background checks, and facility inspections. Financial services: Licenses vary by service — insurance agents, mortgage brokers, investment advisors all have distinct requirements.
Home-Based Business Considerations
If you operate from home, check your local zoning laws. Many residential zones allow light home-based business activity but prohibit customer visits, employees on site, or visible commercial activity. A home occupation permit (typically $25-$100) formalizes your right to operate from home. Skipping this is a common mistake — a neighbor complaint can result in a cease-and-desist order.
How to Research Your Specific Requirements
Step 1: Use the SBA license and permit tool at sba.gov to get a list of requirements by state and industry. Step 2: Check your state's business portal for state-level licensing requirements. Step 3: Check your city and county websites for local business licenses. Step 4: If your industry is regulated, check the relevant state licensing board directly. Step 5: When in doubt, call the relevant agency — most government licensing offices will tell you exactly what you need.
The Verdict
Do not skip this step. Operating without required licenses can result in fines, forced closure, voided contracts, and personal liability. The research takes two to four hours. A compliance service like Harbor Compliance can handle all research and applications for you if you want to outsource it.
