What Is a Seller’s Permit and Does Your Business Need One?

What a Seller’s Permit Is

A seller’s permit is a state-issued registration that authorizes a business to collect and remit sales tax on taxable sales of goods (and, in some states, certain services). It is also commonly used to buy inventory or other resale items without paying sales tax at the time of purchase by issuing a resale certificate to suppliers.

Names vary by state. You may see it called a sales tax permit, sales tax license, sales and use tax permit, reseller permit, or sales tax number.

What a Seller’s Permit Does (and What It Does Not)

What it typically allows you to do

• Collect sales tax from customers on taxable transactions.
• Report and remit collected sales tax to the state on a required schedule (monthly, quarterly, or annually).
• Purchase items for resale without paying sales tax up front (when properly documented).
• Establish your account for sales and use tax filings and correspondence.

What it does not replace

• A general business license or local permit required by a city or county.
• Federal tax registrations (such as an EIN) or state employer registrations if you have employees.
• Industry-specific permits (alcohol, tobacco, fuel, cannabis, food service, etc.).

Does Your Business Need a Seller’s Permit?

Many businesses need a seller’s permit if they sell taxable tangible personal property, sell through online marketplaces in certain situations, or buy inventory for resale. Whether you must register depends on what you sell, where you have sales tax obligations, and how your state treats your activity.

You likely need one if you:

• Sell physical products at retail (in-store, online, pop-up, or events) and your state treats those products as taxable.
• Sell taxable services in a state where specific services are taxed.
• Buy items wholesale for resale and need to provide resale documentation to suppliers.
• Operate temporarily in a state (trade shows, fairs, seasonal sales) where temporary seller registration is required.

You may not need one if you:

• Sell only non-taxable items in your state (for example, certain groceries or prescriptions, depending on state rules).
• Provide only non-taxable services and do not sell taxable products.
• Sell exclusively through a marketplace that is required to collect and remit sales tax for you on all transactions in that state (you may still need registration in some states for other reasons, such as inventory or direct sales).

Common Business Scenarios

Retail stores and eCommerce

If you sell taxable products directly to customers, registration is commonly required before you make sales. This applies to brick-and-mortar retailers and many online sellers, including those shipping into states where they have sales tax responsibilities.

Wholesalers, resellers, and dropshippers

Businesses that purchase goods for resale often need a seller’s permit to support tax-free resale purchases. Dropshipping can be more complex because more than one party may be involved in the taxable transaction, and documentation between seller, supplier, and customer must be handled correctly.

Service businesses that also sell products

Even if your core business is a service (repair, installation, consulting, salons), selling taxable products (parts, retail items, add-ons) can trigger seller’s permit requirements.

Temporary sellers and event vendors

Craft fairs, farmers markets, festivals, and seasonal kiosks often require sellers to register and collect sales tax, even for short-term operations. Some states offer temporary permits for limited-time selling.

Seller’s Permit vs. Resale Certificate vs. Business License

Seller’s permit (sales tax permit)

• State registration to collect and remit sales tax.
• Creates your sales tax account and filing obligations.

Resale certificate

• A document you provide to suppliers to buy items intended for resale without paying sales tax at purchase.
• Usually used in connection with an active seller’s permit.

Business license

• A local or state authorization to operate a business in a jurisdiction.
• Often separate from sales tax registration; requirements vary by city, county, and industry.

For a broader view of licensing requirements beyond sales tax, see business licenses and compliance requirements.

How to Apply for a Seller’s Permit

Seller’s permits are typically issued by a state department of revenue or taxation agency. The application is usually completed online and may require:

• Legal business name and any DBA (assumed name).
• Business entity type (sole proprietorship, LLC, corporation, partnership).
• Business address and locations where you sell.
• Owner/officer information.
• Start date of taxable sales.
• Estimated sales volume and filing frequency details.
• Federal EIN for many entities (and sometimes for sole proprietors, depending on the situation).

Timing considerations

• Register before making taxable sales when required by your state.
• Plan ahead if you need the permit number to set up vendor accounts, marketplace settings, or event registration.

After You Get the Permit: Ongoing Responsibilities

Collect the right tax

• Apply the correct state and local rates based on your state’s sourcing rules.
• Taxability can vary by product type, customer type (exempt organizations), and use.

File returns on time

• File even for periods with zero taxable sales if the state requires a “zero return.”
• Keep track of due dates and any prepayment requirements in high-volume situations.

Maintain records

• Sales invoices/receipts and tax collected.
• Exemption certificates received from customers (if applicable).
• Resale certificates issued to suppliers and purchase documentation.

Update your account when things change

• New locations, ownership changes, added product lines, or closing the business can require updates or account closure.

Multi-State Sales and Online Selling Considerations

Businesses selling across state lines may have sales tax obligations in more than one state, depending on their in-state presence and sales activity. Requirements differ widely, including how states treat marketplace sales, inventory stored in-state, and remote selling thresholds.

FAQ: Seller’s Permits

1) Is a seller’s permit the same as a sales tax number?

In most states, yes. A seller’s permit often comes with an account number used to file sales and use tax returns and remit the tax you collect.

2) Do I need a seller’s permit if I sell online only?

If you make taxable sales and have sales tax obligations in a state, you may need to register even without a physical storefront. Some marketplace sales may be handled by the marketplace, but direct website sales can still require your own permit.

3) Can I buy wholesale without a seller’s permit?

Many wholesalers require proof of sales tax registration and a resale certificate before selling to you tax-free. Without a permit, you may be charged sales tax on purchases that would otherwise qualify as resale inventory.

4) Do I need a seller’s permit if I sell only at craft fairs or pop-up events?

Often, yes. States commonly require registration for temporary selling, and some offer temporary permits. Event organizers may also request your permit number as part of vendor setup.

5) What if I sell non-taxable items—do I still need a permit?

It depends on your state’s rules and your full product mix. If all your sales are truly non-taxable and you do not make taxable purchases that require reporting use tax, a permit may not be required. If you later add taxable items, you may need to register before selling them.

6) Does a seller’s permit cover multiple business locations?

Some states issue one account with multiple locations, while others require separate location registrations or supplemental permits. Registration details and reporting can change based on how many sites you operate.

7) How long does it take to get a seller’s permit?

Processing times vary by state and by application method. Some approvals are near-instant online, while others take longer if the state needs verification or additional documentation.

8) What happens if I collect sales tax without a permit?

States generally expect businesses to be registered before collecting tax. Collecting tax without proper registration can create compliance issues, including penalties, interest, and problems reconciling collected amounts to a valid account.

9) What is “use tax,” and does a seller’s permit affect it?

Use tax generally applies when taxable items are purchased without sales tax (often from out-of-state sellers) and then used in-state. Many seller’s permit accounts are sales and use tax accounts, meaning you may report both sales tax collected and use tax owed.

10) If I close my business, do I need to cancel my seller’s permit?

Yes in most cases. You typically need to file final returns and formally close the account to stop future filing obligations and notices.
