How to Register for a Sales Tax Permit in Every State

Whether yours is a new company just getting off the ground or an existing e-commerce company working to comply with new out-of-state sales tax laws around the country, you need to register for a sales tax permit in each state where you have nexus, whether physical or economic nexus.

Every state has different regulations and requirements, and five (Oregon, Montana, New Hampshire, Delaware, and Alaska) have no sales tax at all, so it can be overwhelming to get started. This guide is designed to help you gather the right information, find the applicable forms, and apply for a sales tax permit wherever needed.

The Process to Register for a Permit

In most states, you will follow very similar steps to register for a sales tax permit. You’ll need your Employee Identification Number (EIN) from the IRS, as well as your primary place of business, business type, and other relevant business information.

From there, you will need to find the applicable web applications or forms for each state in which you do business that collects sales tax on out-of-state sellers. This does not yet apply to all states, so be sure to research thoroughly (and read our post here to see an updated list of current nexus laws) for where you need to follow these steps.

To help with the process, we’ve outlined below each of the 46 states and districts that collect sales tax, along with their Department of Revenue website and the relevant forms and links you’ll need to register. If you’re unsure which states require you to register, read more about the current requirements here, or contact us to discuss your options.

Registration is just one of many steps you, as a retailer, will need to take in order to comply with sales tax regulations. For a more comprehensive look, read our Complete Guide to Sales Tax.
