The Three Layers of Licensing

Business licensing in the US operates at three levels: federal, state, and local. Most businesses need to navigate all three. The requirements that apply to you depend on your industry, location, and how you operate.

Starting before you have the right licenses can result in fines, forced closure, or personal liability. The good news is that most common licenses are straightforward to obtain once you know what you need.

Federal Licenses and Permits

Most small businesses don’t need a federal license to operate, but certain industries are federally regulated and require specific permits before you can legally operate:

  • Alcohol: Importing, wholesaling, or producing alcohol requires a federal basic permit from the TTB (Alcohol and Tobacco Tax and Trade Bureau)
  • Firearms: Dealers, manufacturers, and importers need a Federal Firearms License (FFL) from the ATF
  • Food: Businesses that manufacture or process food for interstate commerce must register with the FDA under the Food Safety Modernization Act
  • Broadcasting: Radio, TV, and certain wireless businesses need FCC licenses
  • Transportation: Commercial motor carriers operating across state lines need a USDOT number and Operating Authority from FMCSA
  • Agriculture: Organic certification requires USDA accreditation; meat processing requires USDA FSIS inspection
  • Financial services: Investment advisers, money services businesses, and securities dealers have separate federal registration requirements
See the Federal Law database for detailed requirements for each of these categories, including the specific agencies and application processes.

State Business Licenses

Most states require a general business license or registration to operate within the state. This is separate from your entity formation (LLC or corporation registration) it’s an operating license.

Some states have a single statewide business license. Others delegate licensing to counties or cities entirely. A few don’t require a general license at all but regulate specific industries heavily.

Beyond a general license, states regulate dozens of professional and occupational categories requiring specific licenses:

  • Contractors (general, electrical, plumbing, HVAC)
  • Healthcare providers (physicians, dentists, nurses, therapists)
  • Financial professionals (mortgage brokers, insurance agents, financial advisors)
  • Real estate agents and brokers
  • Attorneys and CPAs
  • Cosmetologists, barbers, and estheticians
  • Childcare providers
  • Security personnel

Check the State Law section for your specific state to find the licensing requirements that apply to your profession and industry.

Local Licenses and Permits

Even if your state doesn’t require a general business license, your city or county almost certainly does. Local licensing is where most new business owners get surprised.

Business license: Most cities require a local business license, sometimes called a business tax certificate, renewed annually. Fees typically range from $50 to several hundred dollars depending on your revenue or business type.

Zoning compliance: Before signing a lease or committing to a location, verify that your intended use is permitted in that zoning district. Operating a business in a zone that doesn’t allow it can force you to move at significant cost.

Certificate of Occupancy: If you’re occupying a commercial space, you’ll generally need a Certificate of Occupancy from the local building department confirming the space is suitable for your intended use.

Home occupation permit: Running a business from your home typically requires a permit and compliance with local rules limiting signage, customer traffic, employees, and storage. Rules vary dramatically by municipality.

Health permits: Food service businesses – restaurants, catering, food trucks, bakeries – require health department permits issued at the county or city level, with periodic inspections.

Signage permits: Installing exterior signage typically requires a permit. Size, placement, and illumination are regulated by local sign ordinances.

How to Find What You Need

The most reliable approach is to contact each relevant agency directly:

  1. Check your state’s official business portal, most states have a dedicated “starting a business” page that lists required registrations and licenses
  2. Contact your city or county clerk’s office for local license requirements
  3. Contact your local planning or zoning department before committing to a location
  4. For industry-specific licenses, contact the relevant state regulatory board

The SBA’s website (sba.gov) also maintains a directory of federal license requirements by industry that’s a useful starting point.

Don’t rely solely on advice from other business owners in your industry about what licenses you need. Requirements change, enforcement varies, and your specific circumstances may differ from theirs.

Employer Identification Number (EIN)

If you have employees, operate as a corporation or partnership, or have certain types of retirement plans, you need an Employer Identification Number (EIN) from the IRS. It’s free to apply online at irs.gov and you receive it immediately. Think of it as a Social Security Number for your business – you’ll need it for bank accounts, tax filings, and many license applications.

Ongoing Compliance

Most licenses need to be renewed annually, biennially, or on a cycle set by the issuing agency. Keep a calendar of all your renewal deadlines. Operating on an expired license is the same as operating without one in most jurisdictions.

Common Mistakes

  • Assuming you don’t need a license. When in doubt, check. The cost of a license is always less than the cost of operating without one.
  • Getting licensed in the wrong jurisdiction. If you operate in multiple cities or states, you may need licenses in each one.
  • Letting renewals lapse. Set calendar reminders 60 days before each license expires.
  • Starting before permits are issued. Some permits require inspections that take weeks. Factor permit timelines into your launch plan.

Where to Go Next

Once licensed, your next priority is understanding your tax obligations. See the Taxes 101 guide for what you owe at the federal and state level. For your specific state requirements, browse the State Law section for your state.
