What is the SST Exemption Certificate, and is it accepted in all SST states?

⚡ TL;DR

The SST Exemption Certificate is a single standardized form accepted by all 24 SST member states — one certificate covers all SST-state transactions for a given buyer. Sellers enrolled through a CSP like TaxCloud are required to accept it, and good-faith acceptance in SST states provides statutory audit liability protection. It is not valid in non-SST states like California, Texas, Florida, or New York.

The SST Exemption Certificate is a single standardized form accepted in all 24 SST member states. One certificate, one buyer, works across all SST states.

Key takeaways

  • Accepted in all 24 SST member states: TX, WA, GA, NC, OH, IN, WI, MN, NE, SD, IA, KS, KY, NV, NJ, RI, OK, AR, UT, VT, WY, WV, ID, and MI (note: specific membership list can evolve; confirm current members at streamlinedsalestax.org)
  • Single form, multiple states: the buyer fills out one SST certificate indicating exemption reason; the seller accepts it for all SST-state transactions with that buyer
  • Accepted by CSP-enrolled sellers: sellers who file through a Certified Service Provider (CSP) like TaxCloud are automatically required to accept the SST certificate: the CSP program standards mandate it
  • Exemption reasons covered: the SST certificate covers all standard exemption types: resale, nonprofit, government, manufacturing, agriculture, and others: the buyer checks the applicable reason
  • Good-faith protection: sellers who accept SST certificates in good faith receive audit liability protection in SST member states; if the buyer provided fraudulent information, the seller is shielded
  • Not valid in non-SST states: the SST certificate is not accepted in CA, TX (non-SST), FL, NY, AZ, CO, IL, and other non-SST states, state-specific or MTC certificates are needed for those states

Frequently asked questions

What is the SST Exemption Certificate?
The Streamlined Sales Tax Exemption Certificate is a standardized certificate accepted by all 24 SST member states as a substitute for each state's individual exemption form. A buyer completes one form indicating the reason for exemption and the SST member states where the exemption applies. Sellers registered through the SST program (including CSP-enrolled sellers like TaxCloud customers) are required to accept the SST certificate.
Does using the SST Exemption Certificate give the seller any audit protection?
Yes. In SST member states, sellers who accept exemption certificates in good faith through the SST program receive audit liability protection: the buyer, not the seller, bears liability if the certificate turns out to be fraudulent or misused. This is one of the meaningful compliance benefits of SST enrollment for sellers with significant B2B sales.
