National business license guide
Last updated: August 1, 2026
There is no single license list that fits every U.S. business. The answer changes with your activity, address, products, workers, and industry.
The safest method is to build a license map. You check each government layer, use the exact name of each requirement, and save the official answer before you spend money or open.
Bottom line
Start with five facts: what you do, where you do it, what you sell, whether people work for you, and whether the activity is regulated. Then check federal, state, county, and city rules separately.
A business may need an LLC filing, DBA, seller’s permit, local business tax registration, zoning approval, home occupation permit, professional license, health permit, or federal permit. These are different items. One does not usually replace the others.
The U.S. Small Business Administration license and permit guide confirms that requirements and fees depend on business activity, location, and government rules.
Quick start: build your license map
- Write one plain sentence that explains exactly what the business will do.
- List every place where work, storage, sales, deliveries, or customer visits will happen.
- Mark each address as inside a city, inside a town, or in an unincorporated county area.
- List every product and service you will sell, including food, alcohol, digital items, and taxable services.
- Write down whether you will use your legal name, an LLC name, or a trade name.
- Note whether you will hire employees, use contractors, or have workers report to a site.
- Check whether your work is a licensed occupation or regulated industry.
- Contact the official agencies, save their pages, and record renewal dates.
For a shorter companion list, use the BLG business license checklist for beginners.
Write down the facts agencies actually need
Do not begin with, “I need a business license.” That question is too broad. An agency can give a better answer when you describe the real activity and location.
- Activity: What work will you perform? Include every side activity, not only the main service.
- Operating location: Will you work from home, a shop, an office, a vehicle, a booth, a shared kitchen, a warehouse, or customer sites?
- Visits and storage: Will customers visit? Will you store inventory, food, tools, chemicals, equipment, or work vehicles?
- Sales: Will you sell physical goods, digital products, food, alcohol, tobacco, admissions, rentals, or taxable services?
- Workers: Will you hire employees, pay contractors, or have people work at your home or business site?
- Regulated work: Does the activity involve health, food, childcare, construction, beauty, transportation, finance, animals, alcohol, environmental risks, or another regulated field?
Use a clear sentence: “I will sell packaged baked goods online, store them at my home in [city], ship within the state, and attend two local markets each month.” This gives an agency far more useful facts than “I have an online business.”
Check federal, state, county, and city rules separately
The same business can have duties at more than one level. BLG’s guide to city licenses, county licenses, and state registration explains why these layers should not be combined.
| Layer | What it may handle | Where to start |
|---|---|---|
| Federal | EIN, federal taxes, and permits for federally regulated activities | IRS, SBA, and the federal agency that regulates the activity |
| State | Entity filings, tax accounts, sales tax permits, employer accounts, professional boards, and state industry licenses | Official state business portal, filing office, tax agency, labor agency, and licensing board |
| County | County business taxes, assumed names, health permits, planning, zoning outside city limits, and inspections | County clerk, tax office, planning department, health department, or business license office |
| City or town | Business license, business tax registration, zoning, home occupation, occupancy, building, fire, sign, and activity permits | City clerk, finance, revenue, business licensing, planning, building, fire, or health office |
| Private rules | Lease, HOA, insurance, marketplace, franchise, event, and payment-platform requirements | Your contract, landlord, insurer, platform, or event organizer |
Use the USAGov local government finder when you cannot find the correct city or county website.
Do not mix up these common terms
Government offices use different names. Ask for the exact item, not a general package. The BLG comparison of business licenses, LLCs, DBAs, and seller’s permits gives a fuller explanation.
| Item | What it usually does | What it does not usually do |
|---|---|---|
| LLC or corporation filing | Creates a state legal entity | Does not approve a location or replace tax, zoning, or industry permits |
| DBA, trade name, assumed name, or fictitious name | Registers a public business name when required | Does not create an LLC or give permission to operate |
| Seller’s permit or sales tax registration | Creates a state tax account for taxable sales when required | Does not replace a local business license or zoning approval |
| Local business license or business tax registration | Registers or taxes a business operating in that local area | May not cover zoning, health, building, fire, or professional rules |
| Home occupation permit | Reviews business use of a residential address | Does not form an entity or create a sales tax account |
| Certificate of occupancy | Confirms that a space may be occupied for an approved use | Does not replace every business or industry license |
| Professional or occupational license | Allows a person or business to perform regulated work | Does not always replace local registration and location approvals |
Step-by-step: how to find your requirements
1. Map every business activity
List the main activity and every extra activity. A coffee shop may also roast beans, sell packaged food, play music, put tables outside, install a sign, and deliver orders. Each activity can point to a different office.
Do the same for a service business. A contractor may perform regulated trade work, store tools at home, use commercial vehicles, hire workers, and pull job permits in several cities.
2. Map every location
Your mailing address is not always your operating location. Include the home where records or stock are kept, the shop where customers visit, the kitchen where food is made, the vehicle used for sales, and each city where mobile work is performed.
Check zoning before signing a lease. The SBA’s guide to choosing a business location notes that location affects taxes, zoning, and regulations.
For home-based work, review BLG’s home occupation permit guide. Local staff may ask about visits, parking, deliveries, storage, signs, noise, employees, equipment, and the amount of space used.
3. Check entity, name, and EIN steps
If you form an LLC, corporation, partnership, or nonprofit, use the official state filing office. The SBA business registration guide explains that filing duties depend on structure and location.
If you use a public name that differs from the legal owner or entity name, check DBA, trade name, fictitious name, or assumed name rules. The filing office may be the state, county, city, or more than one office.
After forming a legal entity, check whether it needs an EIN. The IRS EIN page says to form the entity through the state before applying for an EIN. An EIN is a tax ID, not a license. Forming an LLC also does not end the search; see why LLCs may still need business licenses.
4. Check state tax registrations
If you sell goods or taxable services, check the official state tax agency before the first sale. States use names such as seller’s permit, sales tax permit, vendor license, sales tax Certificate of Authority, transaction privilege tax license, or general excise tax license.
Use the IRS directory of state government business pages to reach state tax and employer resources. BLG’s seller’s permit versus business license guide explains the difference between tax registration and local permission to operate.
5. Check city and county rules for the exact address
Search the official local website for “business license,” “business tax,” “business tax receipt,” “occupational tax,” “privilege license,” “zoning clearance,” “home occupation,” and “certificate of occupancy.”
Some states provide permit-finding tools. Examples include California’s CalGOLD permit assistance tool, Washington’s Business Licensing Wizard starting page, the Texas Governor’s Business Permit Office, and the New York Business Express Wizard. These tools are useful starting points, but confirm the result with the agency that issues the permit.
6. Check professional and industry licenses
Search by the work itself, not only by the business name. A salon may need facility and individual licenses. A contractor may need a state trade license, local registration, and permits for each job. A childcare business may need licensing, background checks, inspections, and zoning review.
The CareerOneStop License Finder can help identify state occupational licenses. Confirm every result on the licensing board’s official page.
Food businesses should start with state and local health or agriculture agencies. Some food facilities also fall under federal rules; the FDA’s How to Start a Food Business page explains federal starting points. Alcohol producers, importers, wholesalers, and some other alcohol businesses should check TTB permit and registration applications as well as state and local alcohol rules. Businesses that create air, waste, chemical, water, pesticide, or other environmental issues can use the EPA’s small business compliance resources.
7. Add employee and workplace duties
Hiring can trigger employer tax registration, unemployment insurance, workers’ compensation, new-hire reporting, wage rules, workplace notices, and safety duties. These may not be called business licenses, but they belong on the same compliance map.
Use the U.S. Department of Labor’s workplace poster page and state labor office directory. OSHA’s Compliance Assistance Quick Start can help a new employer identify safety resources that may apply.
8. Check federal permits only when the activity points there
Most ordinary businesses do not have one general federal business license. Federal permits are tied to specific activities, such as certain alcohol, aviation, transportation, broadcasting, wildlife, fisheries, mining, nuclear, firearms, import, or export work. Start with the SBA federal list, then use the regulating agency’s official page.
For import and export questions, the USAGov small business page explains that many items do not need a license, while some products need a permit, license, certification, or export-control review.
Outdated checklist warning: FinCEN currently says entities created in the United States and their beneficial owners are exempt from BOI reporting. Certain foreign entities may still have duties. Check the current FinCEN BOI page instead of relying on an older startup checklist.
9. Check private rules without confusing them with government approval
A marketplace, payment processor, delivery app, landlord, HOA, insurer, franchise, commercial kitchen, fair, or farmers market may ask for permits or insurance. Its approval does not replace government requirements. A government license also does not force a private platform or landlord to accept the business.
Online businesses still have a real operating location, tax facts, products, and local rules. See BLG’s guide on whether online businesses need a license.

Real-world examples
These examples show how to think. They are not complete license lists for every location.
| Business model | What to check first | Often missed |
|---|---|---|
| Freelancer working from home | Local business registration, home occupation rules, state tax treatment, and professional licensing if regulated | Assuming no customer visits means no local rule |
| Online seller storing inventory at home | State sales tax account, local home-business rules, DBA if needed, and marketplace duties | Deliveries, storage, resale documents, and sales in other states |
| Cleaning or mobile service business | Local licenses where based and where work occurs, state tax rules, employer duties, and contract insurance needs | Crossing city lines and storing vehicles or chemicals at home |
| Food truck or market vendor | Health permit, mobile vending approval, fire review, sales tax, commissary rules, event approval, and local parking rules | Needing approval in each selling location |
| Retail storefront | Zoning, certificate of occupancy, local business tax or license, sales tax, building, fire, and sign permits | Signing a lease before the use is approved |
| Licensed professional or trade | State board license, business or firm license if required, local registration, job permits, and insurance or bond rules | Believing an individual license covers the business entity and every city |
Phone and email scripts
Keep your request short. Ask the agency to point you to the official rule or application page.
City or county
Hello. I am checking requirements for a [business type] at [address or general location]. The business will operate from [home, shop, office, vehicle, customer sites, or online] and will [short activity description]. Will I need a local business license, business tax registration, zoning clearance, home occupation permit, certificate of occupancy, health permit, fire review, sign permit, or another approval? Please send me the official page for each item.
State tax agency
Hello. I plan to sell [products or services] to customers in [state or states]. Which tax registration should I review before the first sale? Does the state use the term seller’s permit, sales tax permit, vendor license, or another name? Please send the official registration and filing pages.
Licensing board
Hello. I plan to offer [exact service] through a [sole proprietorship, LLC, corporation, or other setup] in [state and local area]. Does the person, business entity, location, or each branch need a license, registration, exam, inspection, bond, insurance, or supervision? Which local office should I also contact?

Common mistakes
- Stopping after forming an LLC. Entity formation does not approve the location, sales, profession, or local operation.
- Checking only the state. Many business licenses, tax receipts, zoning approvals, and occupancy rules are local.
- Using only a mailing address. Agencies may care where work, storage, customer visits, deliveries, and vehicle parking happen.
- Calling every item a business license. Use the exact terms so you reach the correct office.
- Assuming online means unregulated. Online sellers still have tax, product, home-location, and platform facts.
- Signing a lease before zoning review. A landlord’s approval does not prove the planned use is allowed.
- Relying on a paid filing site as the final source. Use the issuing agency for current rules, forms, fees, and deadlines.
- Forgetting changes. A move, new worker, new product, new city, sign, vehicle, kitchen, or customer-facing space can change the answer.
What to do when the answer is hard to find
- Search the official city website for business license, finance, revenue, clerk, zoning, home occupation, and occupancy.
- Search the county site for business tax, assumed name, health, food, planning, and unincorporated-area rules.
- Search the state site for start a business, tax registration, professional licensing, labor, and your exact activity.
- Ask each office, “If your office does not handle this, which office should I contact next?”
- Ask whether the answer changes for your exact address, business entity, workers, or sales method.
- For an expensive, regulated, multi-state, or high-risk launch, ask a qualified attorney, CPA, insurance professional, or licensing specialist to review your map.
Save records and track renewals
Do not save only the license number. Keep the proof trail:
- Official agency and department name
- Exact license, permit, registration, tax account, approval, or inspection name
- Official application and rule pages
- Address, activity, entity, person, vehicle, or location covered
- Application date, approval date, account number, and expiration date
- Fee receipt and current fee page
- Renewal deadline, renewal method, and login information
- Emails, inspection reports, conditions, and notes from calls
The SBA’s stay legally compliant guide notes that renewal requirements vary. Recheck your map before moving, hiring, adding services, opening another location, or selling in a new area.

FAQ
Is there one website that lists every license my business needs?
No. National and state tools can give you a starting list, but no single website can guarantee every federal, state, county, city, zoning, tax, industry, and private requirement. Confirm each item with the agency that issues it.
Should I form an LLC before checking licenses?
You can research licenses before forming an LLC. If you decide to form a legal entity, complete the state filing before applying for its EIN. The LLC does not replace local licenses, tax registrations, zoning approvals, or professional permits.
Do home-based and online businesses need licenses?
They may. The answer depends on the address, city or county, products, taxable sales, customer visits, storage, deliveries, signs, workers, and regulated activities. Check both local home-business rules and state tax or industry rules.
What is the first local office to contact?
Start with the city or county business licensing, finance, revenue, clerk, planning, or zoning office. The correct first office depends on whether the address is inside city limits and what the business will do.
Is a seller’s permit the same as a business license?
No. A seller’s permit is usually a state sales tax registration for taxable sales. A business license is a broader term that often refers to local permission or registration. A business may need both.
When should I recheck my license map?
Recheck before you start, move, hire, open another location, change the business name or entity, add products or services, work in a new city or state, remodel a space, add signs, or renew an approval.
