License basics
Last updated: August 1, 2026
A seller’s permit and a business license do different jobs. A seller’s permit is usually a state sales-tax account for taxable sales. A business license is usually a city, county, or state registration that lets a business operate in a place or activity.
You may need one, both, or neither. The answer depends on what you sell, where you work, how customers buy from you, and whether your product or service is regulated.
Bottom line
You likely need to check a seller’s permit if you sell taxable goods, taxable services, rentals, digital items, or other taxable products under your state’s rules.
You likely need to check a business license if you run a business from a home, office, shop, warehouse, booth, vehicle, job site, or other location covered by city, county, or state rules.
A seller’s permit does not normally approve your location. A business license does not normally let you collect sales tax. A retail shop, home-based product seller, wholesaler, or online store may need both.
Quick start: check these four things
- List exactly what you sell. Separate physical products, services, digital goods, rentals, repairs, food, and wholesale sales.
- Check your state tax agency. Ask whether your sales require a seller’s permit, sales-tax permit, Certificate of Authority, vendor license, or tax registration.
- Check the city and county tied to your business address. Ask about a business license, business tax certificate, business tax receipt, home occupation approval, zoning, and occupancy rules.
- Check special rules. Food, alcohol, tobacco, construction, health, beauty, childcare, transportation, and professional work can require extra permits.
For a broader start-to-finish list, use the business license checklist for beginners.
Seller’s permit vs business license: quick comparison
| Question | Seller’s permit | Business license |
|---|---|---|
| Main purpose | Registers a business for sales and use tax or a similar state tax duty. | Registers or approves a business to operate in a place or regulated activity. |
| Usual government level | State tax, revenue, taxation, or comptroller agency. | Often city or county. Some states also issue general or activity-based business licenses. |
| Common names | Seller’s permit, sales-tax permit, sales and use tax permit, Certificate of Authority, vendor license, tax registration. | Business license, business tax certificate, business tax receipt, occupational tax certificate, privilege license, general business license. |
| Common trigger | Selling taxable goods or services, leasing taxable property, or making other taxable sales. | Operating from a location, doing business in a jurisdiction, or entering a regulated trade. |
| Collects sales tax? | Usually, when the account covers taxable retail sales. | Usually not by itself. |
| Approves zoning or a storefront? | No. | Not always. Separate zoning, building, fire, or occupancy approval may still be required. |
| Forms an LLC? | No. | No. |
| Registers a DBA? | Usually no. | Usually no, unless one portal combines separate filings. |
| Can the same business need both? | Yes. | Yes. |

Which one do you need?
You sell physical products
Check the state seller’s permit or sales-tax registration first. Then check the local business license, home business, zoning, event, or storefront rules tied to your address.
You sell services only
Do not assume you are outside sales-tax rules. Some states tax certain services. Even when your service is not taxable, your city or county may still require a local license or tax registration.
You buy inventory wholesale
Check whether you need a seller’s permit before you can issue a resale certificate or receive a reseller permit. The document used for wholesale purchases is not always the same as the tax account.
You work from home
Check sales-tax rules for what you sell and local rules for what you do at home. Inventory, deliveries, signs, workers, customer visits, noise, parking, food, and hazardous materials can change the answer.
You sell only through a marketplace
The platform may collect sales tax on covered sales, but that does not automatically remove your state registration, filing, local license, zoning, or product-permit duties.
You sell nothing taxable
You may not need a seller’s permit. You may still need a city or county business license, a professional license, a DBA filing, an employer account, or zoning approval.

What a seller’s permit does
A seller’s permit is usually a state tax registration. It may allow or require you to collect sales tax from customers, report taxable sales, file returns, and send the collected tax to the state.
California requires a seller’s permit when a person or business is engaged in business in the state and plans to sell or lease tangible personal property that would normally be taxable at retail. Wholesalers and retailers must apply.
New York requires sellers of taxable tangible personal property or taxable services to register as sales-tax vendors before beginning business. That rule can apply to home sellers, temporary vendors, and people who sell only once a year when the sale is taxable.
Think of it as a tax account, not full operating approval
A seller’s permit may tell the state that you are responsible for sales tax. It does not normally tell your city that your home business, shop, warehouse, sign, food operation, or customer traffic is allowed.
Sales that often require a state check
- Clothing, furniture, crafts, tools, electronics, beauty products, and other physical goods.
- Taxable food, prepared food, beverages, or vending sales.
- Rentals or leases of taxable property.
- Repairs, installation, fabrication, or mixed product-and-service jobs.
- Sales at fairs, markets, pop-ups, festivals, and temporary locations.
- Direct website sales, social-media sales, marketplace sales, and wholesale sales.
Do not collect “sales tax” just because you think you may need a permit. First confirm that the item is taxable, that you are registered when required, and that you are using the correct rate and filing process.
Seller’s permit names and rules are not the same in every state
These examples show why you should search the official tax agency for your own state instead of relying on one national term.
| State | Official term or system | Useful current detail |
|---|---|---|
| California | Seller’s permit | CDTFA says online registration is free. The permit itself has no fee, although a security deposit may be required in some cases. Separate permits may be needed for different locations. |
| New York | Sales-tax Certificate of Authority | The state says businesses generally must apply at least 20 days before beginning activity that requires collection of sales tax or use of exemption certificates. See the state’s selling products or services guidance. |
| Texas | Sales and use tax permit | The Texas Comptroller says businesses engaged in business in Texas that sell or lease tangible personal property or sell taxable services should use the Texas Online Tax Registration Application. The agency currently advises allowing two to three weeks to receive the permit. |
| Florida | Certificate of Registration for sales and use tax | Florida lists retail sales, taxable rentals, admissions, taxable services, and other activities on its sales and use tax page. Registered dealers also receive an Annual Resale Certificate for qualifying resale purchases. |
| Washington | Business License Application and tax registration | Washington combines several state and local steps. Its Business License Application can cover state registration and some city, county, or state endorsements. A separate tax-registration endorsement applies when listed triggers are met. |
| Oregon | No general statewide sales tax | Oregon says it has no general sales or use transaction tax. Its sales-tax guidance explains that an Oregon buyer may use an Oregon Business Registry Resale Certificate for some out-of-state purchases, but this is not an Oregon seller’s permit. |
| Delaware | State business license and gross receipts tax | Delaware has no state sales tax, but it generally requires an annual business license and imposes gross receipts tax on many sellers and service providers. The state’s One Stop licensing page explains how to register. |
Do not copy another state’s paperwork. A Texas resale certificate, California seller’s permit, Florida Annual Resale Certificate, and Washington reseller permit are different documents under different rules.
What a business license does
“Business license” is a broad label. It may mean permission to operate, a local tax account, a yearly registration, or an activity-based license. The issuing office may be a city finance department, county clerk, tax collector, licensing division, or state agency.
The name can be misleading. Los Angeles requires people or entities conducting business in the city to obtain a Business Tax Registration Certificate. Seattle says anyone doing business in the city must have a Seattle business license tax certificate and renew it each year by December 31.
Other places may have no general license for every business. They may regulate only certain trades, or they may rely on zoning, a certificate of occupancy, health permits, professional licenses, and other approvals.
A local business-license check may be needed when you:
- Run a business from a home, apartment, garage, studio, office, shop, warehouse, or storage space.
- Visit customers, deliver goods, perform installations, repair property, or work at job sites.
- Open a storefront, restaurant, salon, workshop, daycare, gym, or professional office.
- Use signs, commercial vehicles, equipment, employees, customer parking, or regular deliveries.
- Sell at events, on sidewalks, from a booth, from a mobile unit, or at temporary locations.
- Work in a regulated trade or profession.
Your address matters because location controls many taxes, zoning rules, and permits. The SBA’s business-location guide explains that state, city, and neighborhood choices affect taxes and regulation.

Seller’s permit vs resale certificate
A seller’s permit is usually your state sales-tax account. A resale certificate is usually a document you give a supplier when you buy inventory or components that you will resell, when state law allows the purchase without sales tax.
California’s Sales for Resale guidance says a purchaser in the business of selling tangible personal property may issue a resale certificate for items that will be sold in the regular course of business. Texas says a seller may accept a properly completed Texas resale certificate instead of collecting tax on a qualifying purchase for resale.
Florida’s Annual Resale Certificate is issued to businesses registered to collect sales tax. It expires on December 31, and a new certificate is issued each year while the business remains registered. Florida warns that it cannot be used for furniture, office equipment, computers, supplies, personal use, or other items the business will use instead of resell.
Washington uses a state reseller permit. Washington says these permits allow qualified retailers, wholesalers, and manufacturers to buy certain items for resale without paying retail sales tax. Most are valid for four years, but some are valid for two years.
Resale certificate warning
Do not use a resale certificate as a store discount card. It is not for personal purchases, office furniture, tools, equipment, or supplies that your business will consume. Misuse can lead to tax, interest, penalties, or other enforcement.
Online stores and marketplace sellers
Online sellers may have duties in their home state, where inventory or workers are located, where sales thresholds are met, and where the business is based.
A marketplace such as Amazon, Etsy, eBay, or Walmart may collect and send sales tax on covered marketplace sales. The Streamlined Sales Tax marketplace seller guidance warns that a marketplace seller may still have to register or file in some states.
The platform may handle:
- Sales-tax collection on transactions covered by the state’s marketplace law.
- Sending that tax to the state.
- Providing sales and tax reports for platform transactions.
The platform usually does not handle:
- Your city or county business license.
- Your home occupation permit, zoning approval, or lease restrictions.
- Sales tax on direct website, in-person, wholesale, or other off-platform sales.
- Your DBA, LLC, EIN, employer accounts, or income-tax duties.
- Food, alcohol, health, product-safety, professional, or trade permits.
A seller that must register in several participating states may be able to use the free Streamlined Sales Tax Registration System. Registration does not decide whether you owe past tax or remove other state and local duties.

Federal, state, county, city, and private layers
| Layer | What to check | What it does not replace |
|---|---|---|
| Federal | EIN, federal taxes, and licenses for certain regulated activities such as alcohol, firearms, aviation, broadcasting, transportation, and other federal fields. | State sales-tax registration or local business approval. |
| State | Seller’s permit, tax accounts, entity formation, employer registration, professional licenses, and industry permits. | City zoning, county health approval, or local business licensing. |
| County | Business licensing in unincorporated areas, DBA or fictitious-name filings, health permits, building rules, and local taxes. | State tax registration or city licensing inside city limits. |
| City or town | Business license, business tax certificate, home occupation approval, zoning, signs, fire review, building permits, and certificate of occupancy. | State seller’s permit or professional license. |
| Private platform or property | Marketplace rules, landlord approval, HOA rules, insurance, payment-processor checks, product restrictions, and category approval. | Any government license or permit. |
The U.S. Small Business Administration explains that required licenses and permits depend on business activity, location, and the issuing agency. A permit from one layer does not clear every other layer.
Real-world examples
Home-based candle seller
The candles are physical products, so the seller should check state sales-tax registration. The home address may also trigger a city business license, home occupation approval, zoning rules, or limits on inventory and deliveries.
Freelance graphic designer
The designer may not need a seller’s permit if the state does not tax the service. A city may still require a business license or local tax registration. Selling printed products, templates, digital goods, or merchandise can change the tax answer.
Storefront clothing boutique
The shop will usually check state sales-tax registration before taxable retail sales. It may also need a local business license, zoning approval, certificate of occupancy, building or fire review, and sign approval.
Etsy shop using a spare bedroom
The marketplace may collect tax on covered Etsy sales, but the seller should still check state registration and local home-business rules. BLG’s Etsy seller business license guide covers the platform, home, product, and tax layers.
How to verify what you need
- Write a one-sentence business description. Example: “I will sell handmade soap from home through Etsy and local weekend markets.”
- List every sales channel. Include marketplaces, your website, social media, wholesale, events, deliveries, and in-person sales.
- Find the official state tax agency. The Federation of Tax Administrators state agency directory links to state tax departments.
- Ask whether your exact product or service is taxable. Do not ask only, “Do I need a seller’s permit?” Give the agency the facts.
- Check the city and county for your base address. Confirm whether the address is inside city limits or in an unincorporated county area.
- Ask about the actual operating model. Mention home use, customer visits, inventory, employees, signs, vehicles, food, equipment, and events.
- Check regulated activities. Use the federal, state, and local agency that controls the product, trade, or profession.
- Save proof. Keep permits, account numbers, confirmation pages, tax notices, agency emails, filing dates, and renewal dates.
An EIN is a federal tax ID, not a seller’s permit or business license. Get it free from the IRS EIN page when your business needs one.
Common mistakes
- Stopping after getting a seller’s permit. State sales-tax registration does not usually approve your home, storefront, food operation, sign, or professional work.
- Stopping after getting a city license. A local license does not usually register you to collect state sales tax.
- Calling a resale certificate a seller’s permit. The tax account and the wholesale-purchase document are often separate.
- Assuming services are never taxable. States tax different services, repairs, digital goods, rentals, and mixed transactions.
- Assuming a marketplace handles everything. Marketplace collection may cover only platform sales and only certain tax duties.
- Using a home address without checking local rules. Online work can still affect zoning, parking, deliveries, inventory, signs, and customer visits.
- Ignoring renewals and zero-sales returns. Some licenses renew yearly. Some tax accounts require returns even when no tax is due.
- Paying a private filing site without checking the government fee. Many registrations can be filed directly with the agency. The IRS EIN is free, and California says its seller’s permit has no fee.

FAQ
Do I need a seller’s permit if I already have a business license?
Maybe. A local business license and a state seller’s permit do different jobs. If you make taxable sales, check the state tax agency even when your city has already licensed the business.
Do I need a business license if I already have a seller’s permit?
Maybe. A seller’s permit normally covers sales-tax duties, not local permission to operate. Check the city and county for your business address, home use, storefront, warehouse, events, and regulated activity.
Is a resale certificate the same as a seller’s permit?
No. A seller’s permit is usually the state sales-tax account. A resale certificate is usually a document used to buy qualifying inventory or components for resale without paying sales tax at purchase.
Do service businesses need a seller’s permit?
Sometimes. States tax different services, repairs, rentals, digital products, and mixed transactions. A service business may also need a local business license even when no seller’s permit is required.
Does an online seller need both?
Possibly. The seller should check state sales-tax registration and the local rules for the home, office, warehouse, or other business base. Marketplace tax collection does not automatically replace local licensing.
Is there one national seller’s permit or business license?
No. Seller’s permits and sales-tax accounts are normally state-based. Business licenses may come from a city, county, or state. Federal licenses apply only to certain regulated activities.
Do states without a general sales tax require a seller’s permit?
Not usually for a general state sales tax that does not exist, but other tax accounts, state business licenses, local sales taxes, gross receipts taxes, or industry permits may still apply. Check the official state and local agencies.
