Business Licenses & Permits: What Your Business Needs to Operate Legally
Forming your LLC or corporation creates the legal entity. But in most jurisdictions, you also need licenses and permits to actually operate — at the federal, state, and local level. Requirements depend on your industry, location, and business activities. This guide helps you figure out what you need.
Why Business Licenses Matter
Operating without required licenses isn’t just a technical violation — it can result in fines, forced closure, voided contracts, personal liability, and in some cases criminal charges. Yet it’s one of the most commonly overlooked steps in starting a business, because unlike formation and EIN registration, there’s no single place to check.
The challenge is that licensing requirements come from three different levels of government — federal, state, and local — and each has its own rules, applications, fees, and renewal schedules. A restaurant in Austin, Texas might need a city business permit, a state food service license, a health department inspection certificate, a liquor license, a sales tax permit, a fire department occupancy permit, and a federal employer ID — all from different agencies with different deadlines.
License vs. Permit vs. Registration
These terms are often used interchangeably, but they have different meanings. A license grants permission to engage in a specific activity (selling alcohol, practicing medicine, operating a financial business). A permit grants permission for a specific condition (occupying a building, displaying a sign, operating from a home). A registration is a notification requirement (registering as a contractor, registering for sales tax). In practice, you may need all three depending on your business.
Three Levels of Business Licensing
Requirements come from federal, state, and local governments. You may need licenses from all three.
Federal Licenses & Permits
Most businesses don’t need a federal license — there’s no general “federal business license” in the United States. Federal licensing applies only to businesses in specifically regulated industries. If your business doesn’t fall into one of these categories, you can skip this level entirely.
- ATF — Alcohol, tobacco, firearms, explosives manufacturing or sales
- FCC — Broadcasting, telecommunications, radio frequency devices
- FDA — Food manufacturing, pharmaceuticals, medical devices, cosmetics
- DOT / FMCSA — Commercial transportation, trucking, freight brokerage
- EPA — Activities involving environmental impact, hazardous waste, emissions
- SEC / FINRA — Securities, investment advisory, broker-dealer activities
- USDA — Agriculture, meat processing, organic certification
- SBA — Government contracting (not a license, but registration in SAM.gov)

State-Level Licenses & Permits

Local / City / County Permits
Local licensing is where most businesses encounter requirements — and where the most variation exists. What’s required depends on your city, county, and the specific nature of your business operations.
- City business license / tax certificate: Required in most cities for any commercial activity within city limits
- Zoning compliance / use permit: Confirms your business location is zoned for your type of activity (commercial, retail, industrial, home-based)

Sales Tax Permits: A Closer Look
Sales tax is the licensing requirement that catches the most businesses off guard — especially e-commerce sellers. If you sell taxable goods or services, you need a sales tax permit (also called a seller’s permit, resale certificate, or sales tax license) in every state where you have sales tax nexus.
What Is Nexus?
Physical nexus exists when you have a physical presence in a state — an office, warehouse, employees, or inventory (including Amazon FBA inventory). Economic nexus exists when you exceed a state’s sales threshold — typically $100,000 in sales or 200 transactions in the state per year (thresholds vary). After the Supreme Court’s South Dakota v. Wayfair decision (2018), most states enforce economic nexus for remote sellers.
The 5 States With No Sales Tax
Alaska, Delaware, Montana, New Hampshire, and Oregon have no state-level sales tax. However, Alaska allows local jurisdictions to impose sales tax, so some Alaska cities still require a sales tax permit. For the other 45 states plus DC, you need a permit if you have nexus.
Consequences of Selling Without a Permit
Collecting sales tax without a permit is illegal in most states. Not collecting sales tax when required means you owe the tax out of your own pocket — plus penalties and interest. States are increasingly aggressive about auditing e-commerce sellers. Getting a permit is free or low-cost in most states — the risk of not having one far outweighs the filing effort.
Licensing for Home-Based Businesses
Running a business from home doesn’t exempt you from licensing — but the requirements are usually lighter.
What You Typically Need
- Home occupation permit: Most cities require this — confirms your home business is compatible with residential zoning ($0–$150)
- City business license: Required in most cities regardless of location — home businesses are not exempt ($25–$200)
- Sales tax permit: If selling taxable goods or services — same requirement as any business
- Professional licenses: If your profession requires state licensing, working from home doesn’t exempt you
Common Home Business Restrictions
- No customer foot traffic (or limited by zoning)
- No exterior signage
- No employees working at the home (varies by city)
- Business cannot occupy more than 25–50% of home square footage
- No hazardous materials storage
- No noise, odor, or traffic impact on neighbors
HOA and lease restrictions: Even if your city allows home-based businesses, your homeowners association (HOA) or rental lease may prohibit commercial activity. Check your HOA covenants or lease agreement before setting up. Violating HOA rules can result in fines; violating your lease can result in eviction. These are private agreements — they apply on top of city zoning rules.
How to Find Your Licensing Requirements
There’s no single database. You need to check three levels of government.
Check Federal Requirements
Visit the SBA’s federal license directory at sba.gov. Search by industry. Most businesses don’t need a federal license — but if your industry is regulated (alcohol, firearms, transportation, food manufacturing, securities), you’ll find the relevant agency and application process here.
Check State Requirements
Visit your state’s Secretary of State or Department of Commerce website. Search for “business licenses” or “professional licenses.” Most states maintain a searchable database of required licenses by industry. Also check whether your state requires a general business license and a sales tax permit.
Check Local Requirements
Contact your city clerk or county clerk’s office. Ask what licenses and permits are required for your business type at your specific address. Zoning, health, fire, and building departments may each have separate requirements. Some cities have online portals; others require a phone call or office visit.
Don’t forget renewals. Most business licenses expire annually and must be renewed with updated information and fees. Calendar every renewal deadline the day you receive the license. Letting a license lapse can result in fines, forced closure, or loss of your professional credentials. Many jurisdictions send renewal notices — but the responsibility is yours, not theirs.
Business Licensing Around the World
Licensing structures vary dramatically by country. Key differences in major jurisdictions.
United Kingdom
No general business license required for most businesses. Specific licenses needed for: selling alcohol (premises license from local council), food businesses (register with local authority), financial services (FCA authorization), childcare, taxis, and waste management. VAT registration required above £90,000 turnover.
France
Regulated professions (professions réglementées) require specific qualifications and registration — lawyers, doctors, accountants, architects, artisans. Artisans must register with the Chambre des Métiers. Carte professionnelle required for real estate agents. Licence for selling alcohol. TVA (VAT) registration mandatory above thresholds.
UAE
Every business needs a trade license — commercial, professional, or industrial. Free zone companies get their license from the free zone authority. Mainland companies from the Department of Economic Development (DED). License specifies permitted activities — you can only conduct activities listed on your license. Annual renewal required.
Singapore
No general business license for most activities. Specific licenses from relevant agencies: food shop license (SFA), financial advisory license (MAS), employment agency license (MOM), travel agent license (STB). GoBusiness Licensing portal centralizes applications. GST registration required above SGD 1M revenue.
Germany
Gewerbeanmeldung (trade registration) required for all commercial businesses with the local Gewerbeamt. Handwerk (skilled trades) require Meisterbrief (master craftsman certificate) or equivalent. Freiberufler (freelance professionals) are exempt from trade registration. Industry-specific permits for restaurants, construction, transport.
Canada
Municipal business license required in most cities. Provincial licenses for regulated professions (engineering, law, medicine). Federal licenses for broadcasting, aviation, cannabis, firearms. BizPaL tool helps identify requirements by jurisdiction and activity. GST/HST registration required above CAD 30,000 revenue.
Consequences of Operating Without Required Licenses
The risks go beyond fines — unlicensed operation can undermine your entire business.
Fines & Penalties
Most jurisdictions impose fines for operating without required licenses — ranging from $100 for a missing city business license to $10,000+ for operating without a professional license. Repeat violations escalate penalties. Some states treat unlicensed contracting as a criminal offense.
Forced Closure
City code enforcement can issue a cease-and-desist order forcing you to stop operating immediately until all licenses are obtained. Health departments can shut down food businesses on the spot. This isn’t theoretical — it happens daily, often during the busiest periods.
Unenforceable Contracts
In many states, contracts entered into by an unlicensed business are unenforceable — meaning you can’t sue to collect payment. A contractor who performs $100,000 of work without a required license may be unable to collect a dime in court. The client gets the work for free.

Quick answers to the most common licensing questions.
Do I need a business license for an online business?
Usually yes. Most cities require a business license for any commercial activity conducted within city limits — even if the business is entirely online. You’ll also need a sales tax permit if selling taxable goods in states where you have nexus. A home occupation permit may be required if you operate from home. “Online” doesn’t mean “unregulated.”
Do I need a business license if I have an LLC?
Yes. Forming an LLC creates a legal entity — it doesn’t satisfy licensing requirements. An LLC and a business license serve completely different purposes. The LLC provides liability protection and legal structure. The business license grants permission to operate in a specific jurisdiction. You need both.
How much does a business license cost?
A general city business license typically costs $25–$200 per year. Professional licenses vary widely — a cosmetology license might cost $50, while a contractor’s license could cost $500+. Sales tax permits are usually free. Federal licenses range from free to $10,000+ depending on the industry. Total first-year licensing costs for most small businesses are $100–$500.
Do I need a separate license for each city I operate in?
Potentially yes. If you physically operate in multiple cities (offices, storefronts, job sites), each city may require its own business license. For online businesses, licensing is typically based on where the business is physically located — not where the customers are. Service businesses that travel to client locations may need licenses in each city where they regularly perform work.
What’s a sales tax nexus?
Nexus is the connection between your business and a state that creates a sales tax obligation. Physical nexus means you have a physical presence (office, warehouse, employees, inventory). Economic nexus means you exceed the state’s sales threshold (typically $100K in sales or 200 transactions). If you have nexus, you must collect and remit sales tax in that state.
Do freelancers need a business license?
In most cities, yes — if you’re conducting commercial activity within city limits, you need a business license regardless of your business structure. Some cities exempt very small businesses below a revenue threshold. Professional freelancers (accountants, engineers, lawyers) also need state professional licenses. Check with your city clerk’s office for specific requirements.
What if I’m operating in multiple states?
You need to comply with licensing requirements in every state where you have a business presence. This may mean multiple state-level licenses, foreign qualification (registering your LLC or corp in each additional state), and sales tax permits in each state where you have nexus. Multi-state compliance adds cost and complexity — budget accordingly.
Can I operate while my license application is pending?
It depends on the license type and jurisdiction. Some cities allow you to operate with a receipt showing your application is pending. Others — especially health permits, liquor licenses, and professional licenses — require approval before you can legally begin operations. Never assume you can operate while pending — ask the issuing agency explicitly.
