How to register for a sales tax permit

by TaxJar January 1, 2025

Before you collect sales tax, you must register for a sales tax permit with each state in which your business provides sales. 

Each state’s taxing authority — usually called the [State] Department of Revenue/Taxation — manages sales tax registration. You can register for a sales tax permit yourself, or hire a tax professional to register for your state sales tax permits on your behalf.

When filing online, your business may receive a  sales tax permit number instantly, although some states may take up to 10 business days. If you register via mail, it may take two to four weeks to receive your sales tax permit. 

When to register for a sales tax permit

In the US, businesses must register for a sales tax permit when they have met nexus thresholds in a state. Because thresholds vary by state, sellers must understand the sales tax laws in the states where they make sales to ensure they remain compliant.. In general, having a physical presence in a state creates nexus.

When does a business need to register for a sales tax license? Use these criteria as a guide:

  • When your business is based in a state
  • When your business has physical presence in a state
  • When your business has met economic nexus thresholds in a state
  • When you sell on a marketplace and have nexus in a  state that does not have a marketplace facilitator law
