National business license guide

Last updated: April 27, 2026

There is no single business license that works for every business in every place. A cleaning business, food truck, online shop, contractor, consultant, salon, and home bakery may all have different rules.

The practical way to figure it out is to build a license map. You match what your business does, where it operates, what it sells, whether you have workers, and whether your industry is regulated. Then you check the right federal, state, county, city, and private-platform sources.

Bottom line

To figure out which licenses your business needs, do not start by searching for one broad phrase like “business license.” Start by writing down the facts that agencies use to decide what applies.

Your checklist should answer these five questions:

What exactly will the business do?
Where will the work happen?
Will the business sell taxable products or services?
Will the business have employees, contractors, drivers, or workers on site?
Is the business in a regulated field, such as food, alcohol, construction, health, transportation, childcare, finance, firearms, aviation, or professional services?

The U.S. Small Business Administration explains that license and permit requirements vary by business activity, location, and government rules. That is why the same business may need different permits in different states, counties, or cities. See the SBA’s official guide to applying for licenses and permits.

Quick start checklist

Before you call an agency or fill out an application, gather this information. It will help you get a clearer answer.

Your business name and any trade name, DBA, fictitious name, or assumed name you plan to use.
Your business structure, if known, such as sole proprietor, LLC, corporation, partnership, or nonprofit.
Your main business activity in plain words.
Every place where work will happen: home, storefront, office, warehouse, client sites, vehicle, pop-up booth, farmers market, shared kitchen, or online.
The city, county, and state for each business location.
Whether customers will visit your location.
Whether you will store inventory, equipment, chemicals, food, tools, vehicles, or signs at home or another location.
Whether you will sell physical goods, digital products, food, alcohol, tobacco, professional services, or taxable services.
Whether you will hire employees or pay independent contractors.
Whether your work needs inspections, bonding, insurance, training, testing, background checks, or professional licensing.

If you are forming a legal entity, also check the order of steps. The IRS says that if you are forming an LLC, partnership, corporation, tax-exempt organization, or other legal entity, you should form the entity through your state before applying for an EIN. See the IRS page on getting an employer identification number.

The license layers to check

A business license search is really a layer-by-layer search. A state registration does not always replace a city license. A seller’s permit does not always replace zoning approval. A platform account does not replace government permits.

Layer	What it may cover	Where to check
Federal	Activities regulated by a federal agency, such as certain alcohol, firearms, aviation, commercial fishing, wildlife, broadcasting, maritime, mining, nuclear, import, or export activities.	Start with the SBA license page, USAGov small business pages, and the specific federal agency that regulates the activity.
State	Business entity formation, foreign registration, DBA or trade name rules, sales tax or seller’s permit registration, employer accounts, professional boards, and state industry licenses.	Check your state business portal, Secretary of State or business filing office, state tax agency, labor agency, and professional licensing board.
County	County business tax, assumed name filings, health permits, food permits, property records, local zoning in unincorporated areas, and county-level inspections.	Check the county clerk, tax collector, planning or zoning department, health department, and county business license office if one exists.
City or town	Local business license, business tax certificate, business tax receipt, occupational license, zoning approval, home occupation permit, certificate of occupancy, sign permit, fire inspection, or building permit.	Check the city or town website, business license office, clerk, finance department, planning or zoning department, and building or fire department.
Private platform	Marketplace, app, payment processor, franchise, landlord, commercial kitchen, farmers market, delivery app, or vendor rules.	Check the platform, contract, lease, vendor agreement, marketplace policy, or event organizer rules. These are not government licenses, but they may still affect whether you can operate.

Important: Do not call every requirement a “business license.” Some items are tax registrations, zoning approvals, professional licenses, permits, certificates, inspections, or private approvals. The name matters because the right office depends on the type of requirement.

How to build your license map

Use the steps below to turn a confusing search into a practical checklist.

Describe the business activity clearly.
Write one plain sentence: “I will [do the work] for [customers] in [location].” For example: “I will clean homes for residential customers in Denver,” or “I will sell baked goods online from my home kitchen in Ohio.”
Then list every activity that may trigger rules: selling food, visiting homes, using chemicals, driving, storing inventory, hiring workers, selling taxable goods, working with children, handling animals, making alcohol, offering professional services, or doing construction work.
Separate your mailing address from your operating location.
Licensing offices usually care where business activity happens. A mailing address, registered agent address, or virtual office may not be the same as the place where zoning, inspections, customer visits, storage, or work occurs.
If you work at home, check home occupation rules. If you go to customer sites, check the city or county where the work is performed. If you use a vehicle, cart, booth, or food truck, check mobile vending rules. If you sell online, check both tax rules and the location where you run the business.
Check whether your state has a tax registration or seller’s permit requirement.
If you sell taxable goods or taxable services, your state tax agency may require a sales tax permit, seller’s permit, vendor license, transaction privilege tax license, general excise tax license, gross receipts tax registration, or a similar tax account. The name changes by state.
Start with your state tax agency. The Federation of Tax Administrators maintains a directory of state tax agencies.
Check state business filing and name rules.
If you form an LLC, corporation, or other entity, that is usually handled at the state level. If you use a business name that is not your legal name or registered entity name, you may need a DBA, fictitious business name, assumed name, or trade name filing. The name and filing office vary by state and sometimes by county.
Use your official state website first. USAGov keeps a directory of state government websites.
Check city and county business license rules.
Many local governments require a local business license, business tax certificate, business tax receipt, occupational license, privilege license, or local registration. Some require it even for home-based or online businesses. Others only require it for certain activities or locations.
Use the official city or county website. USAGov also keeps a directory for local governments.
Check zoning before you sign a lease or start from home.
Zoning rules control how property can be used. A business may need zoning clearance, a home occupation permit, a certificate of occupancy, or approval before opening to the public.
This is especially important if customers will visit, employees will work at the site, inventory will be stored, food will be prepared, equipment will be used, noise or traffic may increase, or signs will be posted.
Check industry-specific permits.
Some businesses need special permits because of public health, safety, consumer protection, transportation, or professional licensing rules. Examples include restaurants, food trucks, cottage food, childcare, contractors, salons, tattoo shops, massage, healthcare, real estate, financial services, alcohol, tobacco, cannabis where legal, short-term rentals, security services, transportation, and regulated trades.
Do not assume a general city business license is enough. Ask which state board, county department, city department, or federal agency handles your exact activity.
Check employee and workplace requirements.
If you hire employees, you may need employer tax accounts, unemployment insurance registration, workers’ compensation coverage, workplace posters, safety rules, payroll tax filings, and other employment steps. These are not always called “business licenses,” but they are part of operating legally.
The IRS small business tax center provides resources for small businesses and self-employed taxpayers. The Department of Labor explains that some workplace posting requirements depend on which laws cover the employer, and it provides a workplace posters page. OSHA also offers a Compliance Assistance Quick Start for workplace safety questions.
Check federal permits only when the activity points there.
Most small businesses do not have a general federal business license. But certain activities are federally regulated. The SBA lists examples such as alcohol, aviation, firearms, fish and wildlife, commercial fisheries, maritime transportation, mining and drilling on federal lands, nuclear energy, radio and television broadcasting, and certain transportation activities.
Import and export rules also depend on the product. USAGov explains that many imports and exports do not need a license, but some items may require a license, permit, or other certification. See USAGov’s small business page for import and export starting points.
Write down the source, not just the answer.
For each item, save the official page, agency name, permit name, application link, fee page if available, renewal rule, and the date you checked it. If you call or email an agency, write down who you contacted, when, and what they told you to verify next.

Simple decision tree

Use this decision tree to decide what to check next. It does not replace official rules, but it helps you avoid missing a layer.

Will you form an LLC, corporation, partnership, or nonprofit?
Check your state business filing office first. If you form a legal entity, the IRS says to form it through your state before applying for an EIN.
Will you use a business name different from your legal name or entity name?
Check DBA, fictitious name, assumed name, or trade name rules. The filing office may be state, county, city, or a combination.
Will you sell taxable goods or taxable services?
Check the state tax agency for the correct sales tax, seller’s permit, vendor license, transaction privilege tax, general excise tax, or similar account.
Will the business operate in a city, town, or unincorporated county area?
Check local business license, local business tax, zoning, home occupation, certificate of occupancy, and inspection rules.
Will customers visit, will you store inventory, or will you work from home?
Check zoning, home occupation, fire, building, health, sign, parking, and occupancy rules before you open or sign a lease.
Is your work regulated by industry?
Check the specific state board, county department, city department, or federal agency for that activity.
Will you hire workers?
Check federal and state tax accounts, employer registration, unemployment, workers’ compensation, workplace poster, and safety requirements.
Will you sell through a marketplace, app, event, commercial kitchen, franchise, or landlord-controlled space?
Check private rules too. These do not replace government requirements, but they may add documents you must provide.

Common examples of how the map works

These examples are not a complete answer for every location. They show how to think through the layers.

Business situation	Likely layers to check	Why
Home-based online shop selling physical products	State tax agency, city or county business license office, zoning or home occupation office, marketplace rules	Selling taxable products may trigger a state tax account. Operating from home may trigger local business license or zoning rules.
Freelance designer working from home with no customer visits	City or county business license office, zoning or home occupation office, state tax agency if services are taxable in that state	Some local governments require a license or business tax registration even for home-based service businesses.
Cleaning business serving customers at their homes	City and county business license offices, state tax agency, employer agencies if hiring, insurance or bond requirements if required by contract	The business may work across several local areas. Some customers, landlords, or contracts may require insurance or bonding even when government rules do not.
Food truck or mobile food vendor	State tax agency, city and county vending rules, health department, fire department, commissary or kitchen rules, event rules	Food, mobile vending, parking, fire safety, and local selling locations can each create separate requirements.
Contractor, handyman, plumber, or electrician	State licensing board, local business license office, building department, tax agency, bond or insurance rules if required	Trades are often regulated by state or local licensing boards, and permits may be needed for specific jobs.
Retail storefront	State tax agency, city business license or business tax office, zoning department, certificate of occupancy, building or fire inspection, sign permit	A physical location often adds zoning, occupancy, inspections, signs, and local tax or license steps.
Business importing or exporting goods	Federal import or export agency guidance, customs broker if needed, state tax agency, local business license office	Most products may not need an import or export license, but some items require permits, certification, or export control review.

Tip: Search by activity and location together. For example, search the official city site for “business license home occupation,” the county site for “health permit food vendor,” and the state site for “sales tax permit retail.”

What to ask when you contact an agency

Calling or emailing an agency is often useful when the official website is unclear. Keep the message short. Ask verification questions. Do not ask the agency to give broad legal advice.

Have this ready before you contact them

Your business activity in one sentence.
Your business address or general location.
Whether the business is home-based, mobile, online, storefront, office-based, or at customer sites.
Whether customers will visit your location.
Whether you will sell products, food, alcohol, taxable services, or regulated items.
Whether you will hire employees.
Any trade name, DBA, LLC, corporation, or sole proprietor status if known.

Phone or email script for a city or county office

Hello. I am trying to confirm the local requirements before I start a [business type] in [city or county]. The business will operate from [home, storefront, office, vehicle, customer sites, online, or other location]. We plan to [short description of activity].

Can you tell me whether I should check a local business license, business tax registration, zoning approval, home occupation permit, certificate of occupancy, health permit, fire inspection, building permit, sign permit, or another local requirement?

If your office does not handle one of these, which official office or webpage should I check next?

Phone or email script for a state tax agency

Hello. I am trying to confirm whether my [business type] needs a state tax registration, seller’s permit, sales tax permit, vendor license, or similar account. I plan to sell [products or services] to customers in [state or states].

Which official registration should I review, and where can I find the current rules, filing obligations, and renewal information?

Phone or email script for a professional or industry board

Hello. I am checking whether [activity] requires a professional license, permit, registration, inspection, exam, bond, insurance, or supervised work before I offer it to customers in [state, county, or city].

Can you point me to the official rule, application page, and any local office I should also check?

Write down the agency name, date, person or department contacted, answer given, official page or form they referenced, and any other office they told you to contact.

Common mistakes to avoid

Thinking an LLC is a business license. An LLC is a business structure. It does not automatically give permission to operate, sell taxable goods, use a location, or work in a regulated trade.
Checking the state but skipping the city or county. Local business licenses, business tax receipts, zoning, home occupation rules, and certificates of occupancy are often local.
Using the wrong location. Agencies may care where work happens, where customers visit, where inventory is stored, or where the vehicle or equipment is based.
Assuming online means no license. Online businesses may still have local, tax, home occupation, sales tax, marketplace, or industry rules.
Confusing a seller’s permit with a resale certificate. A seller’s permit or tax registration lets a business collect and remit sales tax when required. A resale certificate is usually used to buy items for resale without paying sales tax at purchase, when allowed by state rules.
Ignoring zoning until after signing a lease. A location may not be approved for the planned use, even if the landlord is willing to rent it.
Forgetting health, fire, or building inspections. Food, childcare, salons, assembly spaces, warehouses, signs, kitchens, and public-facing locations may need more than a basic business registration.
Relying on a blog instead of the official agency. Rules, forms, fees, and renewal dates can change. Use official sources for final decisions.
Forgetting renewal dates. The SBA notes that license, permit, and certificate renewal rules vary, so businesses should keep track and confirm with the issuing office.
Treating platform approval as government approval. Etsy, Shopify, Amazon, Uber, DoorDash, Airbnb, farmers markets, events, landlords, and payment processors may have their own rules, but those do not replace government requirements.

What to save in your records

Once you find a possible requirement, save more than the name. Save the proof trail.

Official agency name.
Official webpage or application link.
Exact name of the license, permit, tax account, registration, certificate, approval, or inspection.
Which location or activity it covers.
Application date, approval date, license number, and expiration date if issued.
Renewal deadline and renewal method, if shown by the official source.
Fee page or fee schedule, if the agency publishes one.
Copies of emails, letters, receipts, inspection reports, and agency notes.
Any conditions, limits, or required updates if your business changes.

Recheck before changes: Review your license map before you move, add a new city, hire workers, add a product line, start selling food, buy a vehicle, add signs, open to customers, change your business name, change your entity, or expand to another state.

Practical next steps

Write a one-sentence description of your business activity.
List every place where the work happens.
Check your state tax agency if you sell goods or taxable services.
Check your state business filing office if you are forming an entity or using a trade name.
Check the city and county where you operate for local business license, tax, zoning, and occupancy rules.
Check industry-specific offices if your business involves food, health, construction, childcare, transportation, alcohol, tobacco, professional services, or other regulated work.
Check employee, workplace poster, payroll, unemployment, workers’ compensation, and safety rules before hiring.
Save the official links, dates, and answers in one folder or spreadsheet.

Official sources to start with

Use these as starting points. Your final answer may still depend on your state, county, city, business type, business address, and current agency rules.

How this guide was checked

This guide was reviewed against current federal starting points from the SBA, IRS, USAGov, Department of Labor, OSHA, and state tax agency directories. Local and state rules can change, and each business fact pattern is different. Always confirm important details with the official agency before you act.

FAQ

Is there one website that tells me every license my business needs?

No. There is no single national website that can guarantee every license, permit, registration, tax account, zoning approval, and private rule for every business. Start with official federal, state, county, and city sources, then confirm unclear items with the agency that handles your location or activity.

Should I form an LLC before checking business licenses?

You can usually research license requirements before forming an LLC. But if you decide to form a legal entity, complete the state formation step before applying for an EIN. An LLC is not a substitute for business licenses, tax registrations, zoning approvals, or industry permits.

Do home-based businesses need licenses?

They may. A home-based business may still need a local business license, business tax registration, zoning approval, home occupation permit, state tax account, or industry permit. This depends on the city, county, state, business activity, customer visits, storage, signs, employees, and products sold.

Do online sellers need a seller’s permit?

It depends on the state, what is sold, where customers are located, and whether the products or services are taxable. Check the official state tax agency for the correct term, such as seller’s permit, sales tax permit, vendor license, transaction privilege tax license, general excise tax license, or another tax registration.

What should I ask a city or county office?

Ask whether your business activity and location require a local business license, business tax certificate, business tax receipt, zoning approval, home occupation permit, certificate of occupancy, health permit, fire inspection, building permit, sign permit, or another local approval. Also ask which official webpage shows the current rule.

How often should I recheck my licenses?

Recheck before starting, moving, opening a new location, hiring workers, changing your business name or entity, adding products or services, selling in a new city or state, or renewing an existing license. Keep copies of approvals and renewal dates in your records.
