License Basics
Last updated: August 1, 2026
A city license, county license, and state registration do different jobs. One business may need only one of them, several of them, or a different permit with another name. The answer depends on your address, business activity, products, workers, and where you serve customers.
Bottom line
State registration usually does not give you full permission to operate at a local address. Forming an LLC, getting a state tax account, or receiving a professional license may still leave city and county steps unfinished.
Cities commonly handle local licenses, business taxes, zoning, signs, and occupancy. Counties may handle unincorporated areas, health permits, tax receipts, or name records. States commonly handle entity filings, tax accounts, employer accounts, and professional licenses. Federal agencies handle EINs, federal taxes, and federally regulated activities.
Quick start: check these four questions first
- What exactly will the business do? Write a plain description such as “home-based web designer,” “mobile car detailer,” “online candle seller,” or “restaurant with alcohol.”
- Where will it operate? List every home, shop, office, warehouse, kitchen, job site, event, and city where you work in person.
- Is the main address inside city limits? A mailing address can use a city name even when the property is in an unincorporated county area.
- What special triggers apply? Check products, food, alcohol, employees, customer visits, signs, construction, regulated work, vehicles, and home-based activity.
Then use the official city, county, state, and federal pages described below. For a broader starting list, use our business license checklist for beginners.
City license vs county license vs state registration
This table is a map, not a national rule. Government offices use different names, and some places combine several steps in one portal.
| Government layer | What it often handles | What it usually does not cover by itself | Common starting office |
|---|---|---|---|
| City or town | Local business license, business tax certificate, zoning, home occupation approval, signs, building work, fire review, and certificate of occupancy. | LLC formation, state sales tax registration, county health permits, or state professional licensing. | City finance office, clerk, licensing office, planning department, or online business portal. |
| County | Licensing in unincorporated areas, local business tax receipts, public health permits, county zoning, assumed-name records in some states, and activity-specific permits. | A city license inside city limits, state entity filing, state tax registration, or federal approval. | County clerk, tax collector, treasurer, licensing office, planning office, or health department. |
| State | LLC or corporation filing, state tax accounts, seller’s permits, employer registration, trade names in some states, and professional or industry licenses. | Approval for your exact address, local zoning, city business taxes, signs, occupancy, or local health permits. | Secretary of State or other filing agency, revenue or tax department, labor agency, or licensing board. |
| Federal | EIN, federal taxes, and licenses or permits for certain federally regulated activities. | State formation, local business licensing, zoning, sales tax, or professional licensing. | IRS, the regulating federal agency, and the SBA license and permit guide. |

First decide: city limits or unincorporated county?
A postal address can use a city name even when the property sits outside that city’s legal limits. The county may then act as the local government.
Use an official city boundary map, county parcel search, planning map, or address lookup. You can also ask the city planning or licensing office to confirm whether the address is inside the city. The SBA business location guide explains why location affects taxes, zoning, licenses, and permits.
Do not assume “outside the city” means “no local rules.” Unincorporated county areas may have county business licenses, zoning, building, health, sign, fire, or home-business rules.
What a city license usually means
A city license is a local approval or tax registration. It may be called a business license, business tax certificate, occupation tax certificate, privilege license, or another local term.
The city may ask where you work, what you do, how many workers you have, whether customers visit, whether you use signs, and whether the space is approved for that activity. The local license may be tied to zoning or an occupancy review.
City rules can apply without a storefront
A home office, online shop, mobile service, consultant, contractor, event seller, or out-of-city company doing work inside the city may still have a local requirement. Seattle, for example, says anyone doing business in Seattle must have a Seattle business license tax certificate and renew it each year by December 31. That is a Seattle rule, not a national rule.
San Diego uses the term Business Tax Certificate and states that businesses operating in the city must obtain it. New York City does not use one blanket license for every business; its official Step by Step tool gives a customized list based on the activity.
City license is not the same as zoning
A business license may record or tax the business. Zoning asks whether the activity is allowed at the address. Chicago states that zoning review and approval are needed before a business license application, location expansion, or change of location can be processed. Review the official Chicago zoning guidance as one example of how closely these steps can connect.
Home-based owners should read our guide to the home occupation permit. A home occupation approval focuses on land use and neighborhood impact. It does not automatically replace a business license, seller’s permit, DBA, or professional license.
What a county license usually means
A county license is a county-level approval, tax registration, or activity permit. It may apply outside city limits or because the county handles that activity across the area.
County licensing in unincorporated areas
Los Angeles County says it licenses certain activities in unincorporated county areas and the contract cities listed on its business license requirements page. Cook County, Illinois, says businesses operating in unincorporated Cook County generally need a county general business license, subject to its rules and exemptions.
These examples show why the legal location matters. A county license for an unincorporated address does not automatically cover work in a nearby city.
County rules can still apply inside a city
Some counties handle public health, food permits, assumed names, local taxes, or other services across city lines. Miami-Dade County, for example, requires a county Local Business Tax Receipt and explains that a business inside a municipality may also need the city’s receipt.
County health departments often regulate food facilities. Santa Clara County’s official food and retail operations page is one example. A restaurant can therefore need a city business license and zoning approval plus a county health permit.
Do not treat every county document as a “county business license.” A county fictitious business name filing, food permit, building permit, tax receipt, or health approval has its own purpose.
What state registration can mean
“Registered with the state” is not a complete answer. It can mean several different filings. Ask for the exact name of the registration and the agency that issued it.
| State item | What it does | Common misunderstanding |
|---|---|---|
| Entity filing | Creates or registers an LLC, corporation, nonprofit, limited partnership, or another entity under state law. | It does not normally approve your city location or replace local licenses. |
| Sales tax or seller’s permit | Registers a business to make taxable sales, collect tax, file returns, or use resale documents under state rules. | It is not the same as a local business license or a resale certificate. |
| Employer registration | Sets up state withholding, unemployment insurance, workers’ compensation, or related employer accounts as required. | An EIN alone does not finish state employer registration. |
| Professional or industry license | Approves a person, facility, or business to perform regulated work. | It may not replace a city license, zoning approval, or occupancy permit. |
| Trade or assumed name | Records a public business name when state law assigns that filing to a state agency. | It does not form an LLC or prove that the business may operate at a location. |
State entity filing
The SBA business registration guide explains that entity registration is usually handled at the state level, while local licenses and permits may still be required. Official filing offices include the California Secretary of State Business Entities Section, the Texas Secretary of State Business Services, the Florida Division of Corporations, and the New York Department of State. These are examples only. Use the official filing agency for your state.
State sales tax registration
If you sell taxable goods or services, check the state tax agency before taking sales. California uses a seller’s permit for many taxable retail sales, as explained by the California Department of Tax and Fee Administration. Texas provides a Texas Online Tax Registration Application. New York tells taxable sellers to register as a sales tax vendor and obtain a Certificate of Authority.
Names and tax rules differ by state. Our seller’s permit vs business license guide explains why the state tax step and local operating step are separate.
One state portal may include local endorsements
Washington is a useful example of a combined system. The Department of Revenue says a business may need to apply for a Washington business license when state, county, or city endorsements apply. Its separate city endorsements list shows which local approvals can be added through the state-run process.
A combined portal is convenient, but read the approval carefully. Separate zoning, health, building, fire, occupancy, or professional steps may still remain.
Federal requirements are a separate layer
Most local businesses do not receive one general federal license. The federal layer usually involves tax identification and any federal regulator for the activity.
The IRS explains who may need an Employer Identification Number. An EIN is a federal tax ID, not a city, county, or state business license. The IRS issues EINs directly without a fee. The IRS business taxes page explains the main federal business tax categories.
Federal licenses or permits can apply to regulated activities such as alcohol, aviation, firearms, commercial fishing, maritime transportation, mining, nuclear energy, broadcasting, or certain transportation work. Start with the SBA’s federal license list, then use the named federal agency’s current instructions.
How the layers work in real life
Home-based freelancer
A freelance designer may need to check a city or county business license, home occupation or zoning rules, a DBA if using another name, state entity filing if forming an LLC, and federal or state tax duties.
Our freelancer business license guide covers the common triggers for home and client-location work.
Online product seller
An online seller may need a state sales tax account, local home-business approval, a city or county license, and product-specific permits. A marketplace collecting sales tax does not automatically settle every local, income tax, permit, or registration duty.
See whether online businesses need a business license.
Storefront
A shop may need state entity and tax registrations, a city license, zoning approval, certificate of occupancy, building or sign permits, fire review, and county permits tied to the activity.
Food business
A restaurant, caterer, food truck, or home food seller may face city licensing and zoning, county or regional health permits, state tax registration, and separate alcohol or food-processing rules.
Mobile service
A cleaner, contractor, detailer, vendor, or repair service may need approval where the business is based and in cities where it performs work. Vehicle, wastewater, street-use, vending, or contractor rules can add more layers.
Use this decision path before you apply
- Describe the work in detail. Include every product, service, delivery method, and regulated activity.
- List every operating location. Include home, office, storage, kitchen, warehouse, events, customer sites, and mobile routes.
- Confirm the legal jurisdiction. Check whether each fixed address is inside city limits or in an unincorporated county area.
- Check the city or county licensing page. Search the official site for the exact local term, not only “business license.”
- Check zoning before signing a lease. Ask whether your activity, customer traffic, hours, parking, signs, equipment, or storage are allowed.
- Check the state entity office. Do this if you plan to form an LLC, corporation, nonprofit, or other registered entity.
- Check the state tax agency. Ask about sales tax, gross receipts, withholding, unemployment, and other accounts that match the business.
- Check professional and industry boards. Do this before advertising or accepting paid work in a regulated field.
- Check federal rules. Get tax information from the IRS and use the correct federal agency for regulated activities.
- Save proof and renewal dates. Keep applications, approvals, receipts, account numbers, inspection records, and agency emails together.

| Mobile or customer-site service | Home-base license plus possible licenses where work occurs. | Professional or contractor license, tax, employer accounts. | Vehicles, street use, wastewater, door-to-door sales, events. |
| Storefront or office | Business license, zoning, occupancy, building, fire, signs. | Entity, sales tax, employer, professional license. | Public health, alcohol, tobacco, security, accessibility, outdoor use. |
Common mistakes
- Thinking an LLC is a business license. An LLC is a state business structure. It does not normally approve a local address or regulated activity.
- Checking only the state. State formation and tax registration may leave city licensing, county permits, zoning, signs, and occupancy unfinished.
- Checking only the city. County health, assumed-name, tax receipt, or unincorporated-area rules may still apply.
- Using the mailing city as proof of jurisdiction. Confirm the legal boundary with an official map or agency.
- Calling every document a business license. Use the exact term so the agency can give the right answer.
- Signing a lease before zoning review. A state registration does not make every address legal for every business.
- Assuming online or home-based means exempt. The place where you manage the business, store goods, or meet customers can create local duties. Read our guide on whether you can run a business from home.
- Ignoring renewals and changes. Moving, adding a location, changing ownership, changing activity, hiring workers, or adding regulated products can trigger updates.
- Paying a third party before checking the official fee. Government filing sites should clearly identify the agency. The IRS, for example, does not charge for an EIN.
What to ask the city, county, or state
Have your business activity, address, ownership type, products, workers, customer visits, and operating model ready.
Jurisdiction script
Hello. I am planning a [business type] at [address]. Can you confirm whether this address is inside the city or in an unincorporated county area, and which office handles the local business license or tax registration?
Permit script
The business will be [home-based / online / mobile / storefront]. We will [describe products, services, customers, storage, and employees]. Which licenses, zoning approvals, tax accounts, health permits, inspections, or professional approvals apply before we start?
Renewal script
What is the exact name of this license or registration? When does it expire, how is it renewed, what changes must be reported, and where can I find the current official fee and instructions?
Ask for the official page, application name, department, and written confirmation. Record the date and the name of the office you contacted.
Keep every layer current
The SBA compliance guide says businesses should maintain their state and local licenses, permits, and certificates. Renewal schedules vary.
- Put renewal dates on a calendar at least 30 and 60 days early.
- Check whether the license follows the owner, entity, activity, or location.
- Report moves, ownership changes, new names, new products, and added locations when required.
- Keep tax accounts active only as long as required and close them correctly when the business stops.
- Save the current official fee page instead of relying on an old receipt or third-party list.

Frequently asked questions
Is state registration the same as a city business license?
No. State registration may form an entity, open a tax account, register an employer, record a trade name, or approve a regulated profession. A city business license usually handles local permission or local tax registration. One does not automatically replace the other.
Do I need a county license if I already have a city license?
Maybe. The county may handle health permits, assumed-name records, county tax receipts, activity permits, or rules for unincorporated areas. Some places require both a city and county local tax receipt. Check the county page for your location and business type.
Does forming an LLC give me permission to open?
Usually not by itself. An LLC is a state business entity. You may still need local licensing, zoning, occupancy approval, a seller’s permit, employer accounts, health permits, or professional licenses.
Which office should I check first?
Start with the exact business address and activity. Confirm whether the address is inside city limits or in an unincorporated county area. Then check the local licensing and zoning offices, followed by the state filing, tax, employer, and professional agencies that match the business.
Can an online business need a city or county license?
Yes. An online business still operates from a place. A home office, inventory room, warehouse, employees, local deliveries, or customer visits can trigger local licensing or zoning rules. State tax and product rules may also apply.
Can one application cover city, county, and state requirements?
Sometimes. A state or local portal may combine several registrations or endorsements. Read the approval carefully because zoning, health, building, fire, occupancy, tax, or professional steps may still require separate action.
Is an EIN a business license?
No. An EIN is a federal tax identification number issued by the IRS. It does not replace a state entity filing, seller’s permit, city or county business license, zoning approval, or professional license.
What happens when I move the business?
A move can change the city, county, zoning district, tax account, license, permit, fire review, and certificate of occupancy requirements. Contact every issuing agency before the move and ask whether to update, transfer, close, or reapply.
