When you register, you’ll be set up to file returns on a quarterly or monthly basis. You must file even when no sales tax is due.

Due dates are as follows:

  • Annual filers: If your sales tax liability is less than $1,000 in a 12 month period, the Department of Revenue Services will change your filing status to annual and notify you in writing
  • Quarterly filers: Q1 returns are due on May 1, while returns for the following quarters are due at the end of the month following the filing period
  • Monthly filers: Returns are due at the end of the month for the previous month
