DOR > About Us > Streamlined Sales Tax Streamlined Sales Tax

Streamlined Sales Tax (SST) is a multi-state initiative to reduce the burden of collecting, reporting and remitting sales and use tax across state lines for both e-commerce and traditional brick-and-mortar businesses.

Participating states continue to implement tax law simplifications, apply standard tax definitions, utilize common forms and procedures and certify tax administration software, to ease tax collection in full member and associate member states. 

For more information about SST, please read the Streamlined Sales Tax Project Executive Summary.
