Streamlined Sales Tax (SST) Member States

Updated

The 24 full-member states that participate in the Streamlined Sales Tax Agreement, which offers uniform definitions, one-stop registration, and simplified filing.

The Streamlined Sales Tax Agreement is a multi-state project that harmonizes definitions and administration to reduce the burden on remote sellers. SST full-member states accept a uniform Multistate Exemption Certificate and offer one-stop registration through the SSTRS (Streamlined Sales Tax Registration System).

If you register in 3+ SST states, use SSTRS for a single registration process. Tennessee is an associate SST member (not listed here) with partial benefits.
