Streamlined Sales Tax (SST) and Certified Service Provider (CSP) Programs

This article applies to:Avalara Returns

The Streamlined Sales and Use Tax Agreement (SSUTA) simplifies sales tax compliance for qualifying businesses in participating states. As a Certified Service Provider (CSP), Avalara works with you to determine if you qualify for the program and helps you register in the states where you need to collect and remit. This includes states with that run their own CSP programs, like Pennsylvania.


Get started with SST

1. Contact your Customer Account Manager (CAM)

Avalara will help you apply to the SST program, or work with you as your CSP in states with individual programs like Pennsylvania.

Contact your Customer Account Manager (CAM) to begin the application process, whether you're an existing customer or just started setting up your company in AvaTax.

2. Work with your Avalara representative

They'll determine your eligibility and collect required information.  Once registration is complete, they'll help you configure your AvaTax account and prepare to file.


How do I know I'm SST?

You have an SSTP ID and Effective Date in AvaTax, under Settings > Company Details.
