What are the key provisions of the SST agreement? A summary of the key provisions of the Streamlined Sales and Use Tax Agreement (as of October 2008) follows:

Changes that impact the administration of sales tax

Section 302 - Tax Bases: This section requires local jurisdictions to be identical to the state tax base. This means that items that are exempt at the state level must also be exempt in the local jurisdictions within that state.

Section 305 - Local Rates and Boundaries: This section creates rules regarding frequency and timing of local rate changes for all member states.

Section 308 - State and Local Tax Rates:

  1. Requires states to eliminate multiple state sales and use tax rates on most items of personal property.
  2. Limits the number of local sales tax rates per jurisdiction and requires that sales and use tax rates be equal.

Section 310 - Sourcing Rules:

Retail sales

  • If an item is received by the purchaser at seller's location, it is taxed at the rate applicable to that location.
  • If it is not received at the seller's location, it is taxed at the location where it is received by the purchaser.
  • There are additional rules covering a myriad of variations of the second option.


  • Section 310.1 provides an election effective in 2010 for using origin-based sourcing.
