Who this is for: Entrepreneurs starting a new business, existing business owners expanding into new locations or industries, and anyone unsure whether their operation needs a license, permit, or both.
A business license is an official government authorization to operate a business in a specific location or industry. Most businesses need at least one license or permit: a general business license from the city or county, and potentially state and federal licenses depending on industry. Not having the right licenses can result in fines, forced closure, and legal liability. The SBA’s business licenses and permits guide is the best starting point for federal requirements.
Business License vs Business Permit: What’s the Difference?
The terms “license” and “permit” are often used interchangeably, but they serve different functions. A business license is a general authorization to operate a business within a jurisdiction. A permit is permission to conduct a specific activity, such as selling food, constructing a building, or handling hazardous materials.
Most businesses need a general business license plus one or more permits based on their activities, industry, and location. The tricky part is that these requirements vary dramatically by state, county, and municipality. There is no single national business license in the United States.
Federal vs State vs Local Licenses
Federal Licenses
Most small businesses do not need a federal license. Federal business licenses and permits are required only for specific regulated industries:
- Agriculture (USDA permits for transporting animals or plants)
- Alcoholic beverages (TTB permit from the Alcohol and Tobacco Tax and Trade Bureau)
- Aviation (FAA certification for aircraft and pilots)
- Broadcasting (FCC license for radio/TV stations)
- Firearms, explosives, and ammunition dealers (ATF license)
- Fish and wildlife dealers and importers (USFWS permit)
- Maritime transportation (FMC licensing)
- Nuclear energy (NRC permit)
State Licenses
Every state requires businesses to register with the state, but state-level license requirements vary. Many professions require a state license regardless of where you physically operate: contractors, electricians, plumbers, real estate agents, medical professionals, attorneys, and accountants, among others. You apply directly through your state’s licensing board or Department of Consumer Affairs.
Local (City/County) Licenses
Most general business licenses are issued at the city or county level. Even home-based businesses often need a local business license. Costs typically range from $25 to $500 per year, with larger cities charging more. Some municipalities charge a flat fee; others calculate it based on revenue or number of employees.
Common License Types by Business Type
| Business Type | Typical Licenses / Permits Needed | Issuing Authority |
|---|---|---|
| Retail store | General business license, seller’s permit (sales tax) | City/county + state |
| Restaurant/food service | Business license, food handler permit, health inspection certificate, liquor license (if applicable) | City/county + state health dept |
| General contractor | State contractor’s license, business license, bond/insurance proof | State licensing board |
| Healthcare practice | Professional medical license, facility license, DEA registration (if prescribing) | State medical board + DEA |
| Home-based business | General business license, home occupation permit | City/county zoning |
| Online business | General business license, sales tax permit (for states where you have nexus) | State(s) where nexus exists |
| Financial services | State money transmitter license or investment advisor registration | State financial regulator |
How to Find What You Need by State
Follow these steps to identify your licensing requirements:
- Check the SBA’s website: The SBA licenses and permits page links directly to each state’s licensing portal.
- Search your state’s business portal: Most states now have centralized business licensing portals (e.g., California’s CalGold, Texas’s Texas.gov business licenses).
- Contact your city or county clerk’s office: For local business licenses and home occupation permits, the city or county clerk is usually the right starting point.
- Check your industry’s state licensing board: Licensed professions (contractors, healthcare, legal) have dedicated boards that govern licensing requirements.
- Consult a business attorney or accountant: For multi-state operations or regulated industries, professional guidance can save you from costly compliance gaps.
Costs and Renewal Timelines
Business license costs vary widely:
- General city/county license: $25 to $500 per year, sometimes based on revenue.
- State professional licenses: $100 to $600 for initial application, $50 to $300 for annual renewal.
- Federal permits (e.g., TTB for alcohol): Variable; some are free, others require surety bonds.
- Health permits for food businesses: $100 to $1,000 depending on jurisdiction and facility size.
Most licenses require annual renewal. Missing a renewal can result in your license lapsing, which means you are technically operating illegally. Set calendar reminders 60 days before each license’s renewal date.

Frequently Asked Questions
Do online businesses need a business license?
Yes, in most cases. Even if your business operates entirely online, you typically need a general business license from your city or county. If you sell products online and collect sales tax, you will also need a seller’s permit in each state where you have sales tax nexus. Online businesses are not exempt from local licensing requirements just because they lack a physical storefront.
What is a seller’s permit and do I need one?
A seller’s permit (also called a resale permit or sales tax permit) authorizes you to collect sales tax from customers and remit it to the state. You need one in every state where you have “nexus,” meaning a significant business presence (physical location, employees, or sufficient sales volume). After the Supreme Court’s 2018 South Dakota v. Wayfair ruling, nexus can be triggered by sales volume alone.
Can I lose my business license?
Yes. Business licenses can be revoked or suspended for non-payment of license fees, failure to renew, health or safety violations, zoning violations, or criminal activity related to the business. Losing your license can force you to close operations until the issue is resolved. Maintaining your licenses and permits in good standing is an ongoing compliance obligation, not a one-time task.
Does a DBA require a business license?
A DBA (Doing Business As) registration is not the same as a business license. A DBA registers your trade name with the state or county so you can operate under that name. You still need to obtain all applicable business licenses separately. In many jurisdictions, you register your DBA with the same office that issues business licenses, but they are distinct requirements.
