To get a business license, you apply through the government agencies that regulate your location and your industry, pay the required fees, and clear any inspections that apply to your space. For most businesses that means a general operating license from your city or county, a tax registration with your state, and, depending on what you do, one or more industry-specific permits on top. A restaurant might need a local business license, a state health permit, a fire inspection, and a sales tax permit before it can serve a single customer. Sorting the layers early is what keeps you out of fines, forced closures, and contracts you can’t enforce.
Figure Out Which Licenses Apply to Your Business
Business licensing runs on three levels: federal, state, and local. Almost no business needs all three, and almost every business needs at least one. Your job at the start is working out which combination fits your situation.
Federal
Most small businesses never touch federal licensing. It only applies when your industry is directly regulated by a federal agency. The Small Business Administration’s list includes alcohol production and sales (Alcohol and Tobacco Tax and Trade Bureau), firearms manufacturing and sales (ATF), aviation (FAA), broadcasting (FCC), interstate transportation of goods (DOT), and commercial fishing (NOAA Fisheries Service).1U.S. Small Business Administration.

State
The state level covers the widest range of businesses. Some states require a general business license for any commercial activity within their borders; others only require industry-specific permits. The SBA recommends starting with your Secretary of State’s website to identify what applies.1U.S. Small Business Administration. Apply for Licenses and Permits Your state Department of Revenue usually handles the tax side. These agencies typically maintain online lookups where you can search by business type.
Local
Cities and counties almost universally require a local business license, tax certificate, or operating permit. These do two things at once: they raise revenue and they confirm that your location complies with zoning rules. Before issuing a license, the local government generally checks that your address sits in a zone designated for the kind of activity you’re proposing. A tax office in a strip mall won’t raise flags. A dog grooming business in a residential neighborhood may need a variance or a home occupation permit. Contact your city clerk’s office or planning department early; zoning is the most common reason applications stall.
Professional Licensing Sits on Top
If you personally practice a licensed occupation, you likely need two things: a professional license proving your qualifications, and a general business license to operate commercially. They come from different offices. Professional licenses are issued by state licensing boards, and the U.S. Department of Education notes that regulated professions are generally licensed at the state level and most require formal postsecondary education as a prerequisite.2U.S. Department of Education. Professional Licensure Fields like cosmetology, engineering, medicine, real estate, accounting, and law all fall in this bucket. A licensed engineer opening a consulting firm needs both the professional engineering license from the state board and a general business license from the city or county.
Voluntary certifications from trade organizations are not the same thing. A certification signals competence; a license is legally required. Operating in a licensed profession without one can bring criminal charges, not just fines.
What to Gather Before You Apply
Application forms vary, but most ask for the same core information. Have these in hand before you start.
Employer Identification Number
An EIN is a nine-digit number the IRS assigns to business entities for tax reporting.3Internal Revenue Service. About Form SS-4, Application for Employer Identification Number (EIN) Partnerships, corporations, and nonprofits all need one whether or not they have employees. Sole proprietors need one if they plan to hire or open a business bank account.
The fastest route is the IRS online application, which issues the number at the end of the session. It’s available to anyone with a principal place of business in the United States and a valid Social Security Number or ITIN, and the IRS recommends applying electronically when possible.4Internal Revenue Service. Instructions for Form SS-4 If you can’t use the online system, you can still file Form SS-4 by fax or mail, but fax takes about four business days and mail takes four to six weeks.3Internal Revenue Service. About Form SS-4, Application for Employer Identification Number (EIN)
Formation Documents and Trade Names
Your application will ask for your legal structure: sole proprietorship, LLC, corporation, or partnership. If you’ve formed an LLC or corporation, keep copies of your Articles of Organization or Articles of Incorporation ready. Those are the documents you filed with the state to create the entity, and they prove the business legally exists.
Planning to operate under a name that differs from your legal name or your entity’s registered name? You’ll need a “Doing Business As” registration, sometimes called a fictitious name filing. A sole proprietor named Maria Garcia who wants to operate as “Sunrise Bakery” needs a DBA. So does “Garcia Enterprises LLC” if it markets itself as “Sunrise Bakery.” Where you file varies by state; some handle it at the county clerk level, others through the Secretary of State.
NAICS Code
Most applications ask for a North American Industry Classification System code, a six-digit number the government uses to categorize your activity. Look yours up on the Census Bureau’s NAICS search tool by entering keywords describing what you do.5U.S. Census Bureau. North American Industry Classification System (NAICS) A coffee shop falls under 722515, Snack and Nonalcoholic Beverage Bars. Getting the code wrong won’t necessarily sink your application, but it can trigger follow-up questions that slow it down.
Owner Information
Expect to provide personal details for each principal owner: full legal name, home address, Social Security Number, and percentage of ownership. Some jurisdictions ask for this on anyone holding more than a set ownership stake. Names and addresses must match exactly across all your documents. Inconsistencies between formation papers and the license application are a common cause of delay.
Sales Tax and Employer Registrations Are Separate
A business license lets you operate. It does not authorize you to collect sales tax, and it does not register you as an employer. Both are separate filings, and if you sell taxable goods or services or plan to hire, you almost certainly need them.
More than 45 states plus the District of Columbia impose sales tax, and each requires businesses making taxable sales to register before collecting tax from customers. Most states charge no fee for the permit itself, though some require a refundable security deposit. Applications go through your state’s department of revenue or taxation.
Physical presence isn’t the only trigger. Most states now use an economic nexus standard, meaning you owe sales tax there once your sales into the state cross a dollar or transaction threshold, commonly $100,000 in annual sales or 200 transactions. Online sellers are the ones most likely to hit this, but any business shipping across state lines should check.
Hiring employees adds another layer. Every state runs an unemployment insurance program, and employers must register with the state labor or workforce agency once wages start. Triggers vary; some states require registration as soon as any wages are paid in a calendar quarter, others set a minimum dollar amount. Federal payroll taxes (Social Security and Medicare withholding) run through your EIN with the IRS.
Home-Based Businesses
Running a business out of your house doesn’t exempt you from licensing. You generally need the same general business license as anyone else, plus a home occupation permit from your local zoning authority.
Home occupation rules are written to keep residential neighborhoods residential, and they can be surprisingly restrictive. Common limits include a cap on non-family employees working at the home (often one or two), a limit on customer visits per day, restrictions on commercial vehicle parking, bans on exterior signage, and caps on what percentage of your living space the business can occupy. Some jurisdictions restrict hours to daytime only. If your business doesn’t fit the standard rules, some places allow a variance or special use permit, sometimes with a public hearing where neighbors can object.
One easily missed issue: even after your city issues a home occupation permit, your homeowners association’s CC&Rs may prohibit commercial activity outright. Those are private contracts, not government rules, and the city has no authority to override them. Read them before you invest in a home-based setup.
How to File, Pay, and Pass Inspection
Most state and local agencies offer online filing portals where you submit the application, upload supporting documents, and pay the fee in one session. If your jurisdiction doesn’t have one, you’ll file a paper application with the city clerk’s office or local licensing board by mail or in person.
Fees vary widely by location, business type, and permits involved. A straightforward general business license may run under $100 in a small town and several hundred in a major metro. Specialized permits — liquor licenses, contractor licenses, health department permits — cost more. Some jurisdictions offer expedited processing for a surcharge if you need approval faster than standard.
Once you’ve submitted, the agency reviews for completeness and compliance. That takes anywhere from a few business days for a simple general license to several weeks for industry-specific permits that involve inspections or background checks.
Inspections
Certain business types require physical inspections before a license issues. Restaurants and food service businesses need health department approval. Businesses open to the public often need fire inspection clearance confirming the space meets code for occupancy, exits, sprinklers, and extinguisher placement. Retail spaces and offices in commercial buildings may also need a building inspection for compliance with local construction codes.
Schedule inspections as early as your jurisdiction allows. A failure doesn’t mean starting over, but it adds weeks for corrections and a re-inspection. For any brick-and-mortar location, inspections, not paperwork, are usually the real bottleneck.
Receiving and Displaying the License
After approval, some agencies email a digital certificate immediately; others mail a physical document. Many jurisdictions require you to display the license prominently at your place of business, where customers can see it. Keep a copy in your records once the license period ends too. The IRS recommends retaining business records as long as they support information on a tax return, and employment tax records for at least four years.6Internal Revenue Service. Recordkeeping
What Happens If You Skip It
Operating without the required license isn’t a calculated risk; the consequences compound. Fines are the immediate problem, and many jurisdictions charge penalties that accrue daily until you come into compliance. If the violation is caught during a routine inspection or after a complaint, the government can issue a cease-and-desist shutting you down on the spot.
In heavily regulated industries — construction, alcohol, firearms, cannabis — unlicensed operation can rise to criminal charges. In less regulated fields, a pattern of unlicensed activity can still be treated as a misdemeanor.
The less obvious hit is contractual. In many states, an unlicensed business cannot enforce its own contracts in court. If a client refuses to pay a $50,000 invoice and you didn’t hold the required license when you did the work, the court may refuse to hear the claim. Insurance may also deny coverage if your policy conditions it on proper licensing. Those downstream problems are harder to fix than the license ever was.
Keeping the License Current
A business license isn’t a one-time filing. Most licenses expire annually or biennially, and renewal means submitting an updated application and paying a renewal fee. Some jurisdictions send reminders. Many don’t. Missing a renewal deadline typically triggers a late fee (commonly a percentage surcharge on top of the standard cost), and letting a license lapse long enough can lead to revocation, forcing you to reapply from scratch.
Most jurisdictions also require you to report material changes within a set timeframe. Moving to a new location, changing ownership structure, adding new business activities, or changing the legal name generally requires notifying the licensing agency. Failing to report changes can void your license even if you’ve kept up with renewal fees.
Put renewal dates on the same calendar as your tax deadlines. If you hold licenses from multiple jurisdictions, they almost certainly expire on different dates, and tracking them in one place prevents the kind of lapse that’s easy to cause and expensive to fix.
