Can I make changes to my filing calendar in an SST state?


As a Streamlined Sales Tax (SST) Customer, you want to know if you can make changes to your filing calendar.




SST accounts cannot make changes to the SER filing calendars related to filing changes/return changes.


  • States where you are registered for SST are required to be filed on a monthly basis, filing a Simplified Electronic Return (SER) under ONE registration ID (SSTID)
  • Each state will still have specific account numbers, but Avalara does not keep these on file since we do not file under these.
  • If you need your specific state ID, please contact the states individually.
