Get started with Streamlined Sales Tax

This article applies to:Avalara Returns

The Streamlined Sales and Use Tax Agreement (SSUTA) is a multi-state effort to simplify and standardize sales tax compliance for businesses that sell in participating states.

As a Certified Service Provider (CSP) for the Streamlined Sales Tax (SST) program, Avalara can help you determine your eligibility, set up AvaTax so that your transaction and exemption data complies with SST requirements, and help you file monthly. 

Tip icon Avalara can become your CSP even if you're already signed up for SST elsewhere, or if you file in a state like Pennsylvania that offers its own CSP program. Just tell your Avalara representative and they'll cover the transition in your implementation.

Before you begin

  • If you're not sure whether you already signed up for SST, go to Settings > Company Details. SST accounts have an SSTP ID and effective date in AvaTax. Alternately, go to Settings > Where You Collect and check whether any states are designated SST Volunteer or SST Nonvolunteer. 
  • If your business hasn't added SST, see Q&A: Streamlined Sales Tax (SST) or watch an introductory video to learn more about the program's benefits and whether you qualify.


  1. Contact Avalara to apply, whether you're brand new to AvaTax or already have an account. When you sign up, you'll get a welcome email with next steps, including:
    • Completing the SST pre-registration form
    • Attending an SST webinar 
  2. Have an initial call with Avalara. A consultant will reach out to schedule the call and then review what's needed for your sales tax implementation to comply with SST standards like tax codes, exemptions, and transactions. 
  3. Work with your Avalara implementation consultant to enroll in SST. We'll help you configure your AvaTax settings and prepare to file in compliance with SST requirements. 

 Avalara will submit your SST registration when your implementation is complete and meets SST requirements.
