Sales tax permits: A state-by-state business guide

It’s illegal for businesses to collect sales tax in a state without first obtaining a sales and use tax permit in that state. However, businesses may not be required to collect sales tax in all the states where they make sales. How do you know if you need a sales tax permit? How do you go about getting one if you do?

Read on to learn all about sales tax permits or jump down to the state-by-state guide to sales tax permits to see state-specific requirements.

Key takeaways

Sales tax permit requirements are determined by nexus. You must register for a sales tax permit in any state where you’ve established sales tax nexus through economic activity, physical presence, or other ties.
A sales tax permit authorizes businesses to collect sales tax. You must obtain a sales tax permit from the state tax department before you start collecting sales tax from residents of that state.
State sales tax licenses have varying renewal periods. In some states, sales tax permits must be renewed annually; in other states, sales tax permits do not expire.

What is a sales tax permit?

A sales tax permit is a state-issued document that legally authorizes a business to collect and remit sales tax. Certificate of registration, retail license, sales tax license, sales and use tax permit, seller permit, seller’s permit, and vendor’s license are some other terms for “sales tax permit” and are sometimes used interchangeably.

In most states, businesses act as intermediaries and collect sales and use tax on behalf of the state. Businesses are required to report and remit the tax they collect to the state tax authorities.

In a handful of states, tax is imposed on the business itself, but businesses can pass it on to customers. Specific licenses and permits are required in these states:

Arizona has a transaction privilege tax (TPT) license.
Hawaii has a general excise tax (GET) license.
New Mexico requires businesses that make taxable sales of tangible personal property in the state to register to obtain a New Mexico Business Tax Identification Number for gross receipts tax (GRT).

There’s no statewide sales tax in Alaska, Delaware, New Hampshire, Montana, or Oregon. However, many cities and boroughs in Alaska, including Ketchikan, have local sales and use tax and require certain businesses to register for sales tax. Select jurisdictions in Montana also have a local sales tax.

In addition to a sales tax permit, businesses typically need one or more state or local business licenses. Exact requirements vary depending on the location and nature of your business.

Who needs a sales tax permit?

You’re required to hold a seller permit in states where you have nexus, which is basically a connection with a state that’s significant enough to trigger a sales tax obligation in that state.

There are several ways for a business to establish nexus with a state:

Economic activity in the state (economic nexus)
Physical presence in the state (physical nexus)
Referrals from in-state entities (click-through nexus)
Ties to affiliates in the state (affiliate nexus)

Numerous states require a business to register as soon as nexus is established, so it’s important to track your nexus in the states where you make sales.

Some states require you to get a temporary or occasional sales tax permit if you occasionally or temporarily make sales in the state. For example, while you don’t need a sales tax permit if you only sell one or two taxable items during a 12-month period in Texas, you may need a Texas sales tax permit if you make three or more sales of taxable tangible personal property in the state during a 12-month period.

Nexus can last longer than you think, so be sure to confirm you no longer have a sales tax obligation with a state before allowing your sales tax permit to expire.

Do online businesses need a sales tax permit?

Online businesses must obtain a sales tax permit and comply with all applicable sales and use tax requirements in states where they have nexus. As noted above, it’s possible to establish nexus even when you don’t have a physical presence in a state.

That said, specific sales tax registration requirements vary by state. Some states provide an exception for out-of-state, online businesses that only sell through a registered marketplace facilitator.

Do marketplace sellers need a sales tax permit?

All states with a general, statewide sales tax require marketplace facilitators that have nexus to register for a seller’s permit then collect and remit sales tax on behalf of third-party (marketplace) sellers.

Registration requirements for marketplace sellers vary depending on the state and the circumstances. In California, for example:

An in-state marketplace seller generally is required to register for a sales tax permit if it has physical presence nexus or economic nexus with California.
A remote marketplace seller generally is not required to register for a sales tax permit or file returns with the California Department of Tax and Fee Administration if it only sells through a registered marketplace that handles sales tax on its behalf.
A remote marketplace seller generally is required to register for a sales tax permit and file returns if it also makes direct sales into California and has nexus with the state.

How do I get a sales tax permit?

Obtaining a seller permit is more straightforward in some states than others. Often, the biggest hurdle is finding the information you need on the department of revenue website.

Most states now encourage businesses to register for a sales tax permit online; it tends to be the quickest option. Registering by mail or in person is typically allowed but often discouraged.

You usually need to provide a lot of information when registering for a sales tax permit, including:

The name and address of your business, along with a description of the business
The name and address of each business owner
Your Federal Employer Identification Number (EIN) and Tax ID Number (TIN)
Your social security number
Your banking information
The North American Industry Classification System (NAICS) codes for products you sell
An estimate of your annual sales in the state

In some states, it can take four weeks or longer to obtain a sales tax permit once you complete your registration, so plan accordingly.

Businesses with a physical presence in the state are required to post their sales tax permit in a conspicuous place. Different requirements may exist for remote sellers.

Do I need to renew my sales tax permit?

Sales tax permits in some states, including California and Texas, are generally good for as long as your business is active, provided all information on the permit is up to date. In other states, such as Connecticut and Pennsylvania, sales tax permits expire and need to be renewed.

See our state-specific sales tax permit information below for more details.

Sales tax permit vs. resale certificate

A sales tax permit authorizes a business to collect and remit sales tax on taxable sales of products and services, as required by law.

A resale certificate allows a business to make tax-free purchases of taxable goods they plan to resell. The resale certificate prevents goods from being taxed twice. Sellers that fail to obtain a resale certificate to validate tax-exempt sales could be held liable for the uncollected tax.
