To register for collecting sales tax, you typically need to visit your state's Department of Revenue or Taxation website. Look for the section on business registration or sales tax permits. Follow the instructions to apply for a sales tax permit, which may involve providing information about your business, such as your business name, address, and type of business. Once your application is approved, you will receive a sales tax permit, allowing you to collect sales tax from customers.

1. First, determine where you have nexus. Keep in mind that New Hampshire, Oregon, Montana, Alaska, and Delaware (the NOMAD states) do not collect sales tax. The remaining 45 states and Washington, D.C. all have some form of transaction tax. Start with where you have physical nexus, then identify where you’ve triggered economic nexus. 2. Next, register in each state in which you have nexus. Registering through Avalara Licensing is easier than registering with individual departments of revenue. 3. After you register, you’ll need to collect sales tax in the states you’ve registered in, then submit returns and remit the taxes to the proper tax authority. Avalara can help with this, end to end.
