If you run a for-profit operation of any size, you almost certainly need a business license, and usually more than one. The people who need a business license include solo freelancers, home-based consultants, online sellers, licensed professionals, retail stores, restaurants, contractors, and multinational manufacturers. The specific mix depends on your industry, your location, your business structure, and whether you have employees.
The confusing part is that “business license” isn’t a single document. It’s a catchall for several different permissions issued by different levels of government, and most businesses need a combination of them.
The Four Layers of Licensing
Think of business licensing as four stacked layers, any of which may apply to you:
- A general operating license from your city or county.
- Industry-specific permits from state agencies (health, environment, alcohol, construction, and so on).
- Professional credentials for individuals in regulated occupations.
- Federal authorization for a narrow set of regulated activities.
A common and expensive mistake is assuming that forming an LLC or corporation with your secretary of state means you’re licensed to operate. It doesn’t. Entity formation gives your business a legal structure and identity. A business license gives you permission to actually conduct business in a specific place. You typically need both, and they come from different offices.
The Local General Business License Almost Everyone Needs
Your city, county, or both will typically require a general business license, sometimes called a business tax certificate or operating permit, before you can legally accept customers or clients. It applies whether you run a restaurant, a consulting firm, or an online store with inventory stored in your garage.
Fees vary widely. Some localities charge a flat fee under $100. Others scale the cost based on your number of employees, gross receipts, or business type. Most require annual renewal. The fee structure is essentially a local tax, and it’s how cities and counties track who is doing business within their borders.
Skipping this step has real consequences. Penalties for operating without a local license commonly include daily fines, cease-and-desist orders, and in some jurisdictions misdemeanor criminal charges. Each day of unlicensed operation can count as a separate offense.
Home-Based Businesses Need a Home Occupation Permit
If you run your business from home, you’ll likely need a home occupation permit on top of your general business license. Residential zoning wasn’t designed for commercial activity, and these permits are how local governments reconcile the two.
Home occupation permits typically restrict how much of your home you can dedicate to business, often no more than 25 percent of total floor area. Many jurisdictions also limit the number of daily customer visits, prohibit outdoor signage or storage of commercial materials, and bar you from hiring employees who work at the residence. Client visit hours are usually restricted to standard weekday business hours. The specifics vary by locality, so check with your city or county planning office before you start.
Professional and Occupational Licenses
Some licenses attach to you as an individual rather than to your business. Doctors, attorneys, accountants, engineers, architects, and dozens of skilled trades such as electricians, plumbers, cosmetologists, and real estate agents all need state-issued credentials before they can practice. State licensing boards set the requirements, which usually combine a minimum amount of education or training, a passing score on a state exam, and often a background check.
This is distinct from a general business permit. A licensed plumber who opens a plumbing company still needs the company’s general business license from the city. The professional license authorizes the individual to perform the work. The business license authorizes the entity to operate commercially. Both are required.
Most professional licenses require continuing education to maintain. Letting one lapse isn’t just a late-fee issue. In many states, practicing a regulated profession without a valid license is a criminal offense, with penalties running from misdemeanor fines for a first offense up to felony charges when unlicensed practice results in serious injury or death.
Sales Tax Permits for Anyone Selling Taxable Goods or Services
If you sell taxable goods or services, you almost certainly need a sales tax permit. This is a separate authorization from your state’s tax agency that allows you to collect and remit sales tax. It is not the same as your general business license, and it’s the one new business owners most often overlook.
Forty-five states and the District of Columbia impose a sales tax. Only Alaska (which has no statewide tax but allows local sales taxes), Delaware, Montana, New Hampshire, and Oregon have no general sales tax. In every state that does impose one, you need a seller’s permit before you start collecting tax from customers.
The requirement reaches beyond your home state. Since the Supreme Court’s 2018 decision in South Dakota v. Wayfair, states can require out-of-state sellers to collect sales tax once they cross an economic nexus threshold, typically $100,000 in annual sales into that state. Every state with a sales tax now enforces some version of this rule. If you ship to customers across multiple states, you may need sales tax permits in every state where you exceed the threshold.
Federal Licenses for a Narrow Set of Activities
Most small businesses don’t need a federal license. But if your activity falls under direct federal oversight, you’ll need authorization from the relevant agency before you open your doors.1U.S. Small Business Administration. Apply for Licenses and Permits
Alcohol is the most common trigger. Importing, distilling, producing wine, or wholesaling distilled spirits, wine, or malt beverages all require a basic permit from the Alcohol and Tobacco Tax and Trade Bureau under federal law.2Office of the Law Revision Counsel. 27 U.S. Code 203 – Unlawful Businesses Without Permit Other federally regulated activities include:
- Commercial aviation and aircraft maintenance, through the Federal Aviation Administration.3eCFR. 14 CFR Part 121 – Operating Requirements: Domestic, Flag, and Supplemental Operations
- Commercial fishing, through NOAA Fisheries by region and fishery type.4NOAA Fisheries. Fishing and Seafood Permits
- Manufacturing, selling, or importing firearms and ammunition, through the Bureau of Alcohol, Tobacco, Firearms and Explosives.1U.S. Small Business Administration. Apply for Licenses and Permits
- Exporting items subject to the Export Administration Regulations, including certain technology, software, chemicals, and defense-related equipment, through the Bureau of Industry and Security.5Bureau of Industry and Security. Licensing

Agriculture, nuclear energy, mining on federal lands, and maritime transportation also carry federal licensing requirements. The SBA’s full list is the best starting point for checking whether your specific activity needs federal authorization.
Hiring Employees Triggers More Registrations
If you plan to hire, you’ll pick up a new set of obligations beyond your basic business license. At the federal level, you need an Employer Identification Number from the IRS if you don’t already have one. The IRS issues EINs for free directly through its website and warns against third-party sites that charge for the service.6IRS. Get an Employer Identification Number
At the state level, you’ll generally need to register for state unemployment insurance tax, set up state income tax withholding, and obtain workers’ compensation insurance. Workers’ comp requirements vary. Most states mandate coverage as soon as you have one employee, though a handful set the threshold at two or more. Registration typically runs through your state’s department of labor or workforce agency. Failing to carry required workers’ comp coverage can mean heavy fines and personal liability for workplace injuries.
Doing Business in Another State
A business formed in one state that conducts business in another state generally needs to “foreign qualify” in the new state. That means filing an application with that state’s secretary of state or division of corporations, appointing a registered agent with a physical address there, and paying a filing fee. Most states also require a certificate of good standing from your home state as part of the application.
Not every out-of-state activity triggers this. Attending a trade show, holding a board meeting, or maintaining a bank account usually doesn’t count as “transacting business.” Having employees, a physical office, or ongoing customer relationships in another state almost always does. Each state defines the threshold differently, and the penalties for operating without authorization, including the inability to enforce your contracts in that state’s courts, make this worth checking before you expand.
What Happens If You Skip It or Let It Lapse
Business licenses aren’t permanent. Most general business licenses require annual renewal, and some professional licenses operate on a two-year cycle. Missing your renewal deadline doesn’t create a grace period in most places. Your license is considered expired the day after it lapses, and you may technically be operating unlicensed until you fix it.
Penalties escalate the longer you wait. You’ll face a late fee immediately, and many jurisdictions increase that penalty over time. Some licensing boards cancel expired licenses entirely and require a full reinstatement rather than a simple renewal. At the extreme, operating with an expired license carries the same penalties as never having been licensed, including fines, cease-and-desist orders, and in some jurisdictions an obligation to return profits earned during the unlicensed period.
Set calendar reminders well ahead of renewal deadlines. A late fee is annoying. Having your license revoked and your business shut down while you reapply is a different category of problem.
