Filing schedule

The timely filing discount depends on the tax liability and is calculated as follows:

  • $0 to $10 - the full amount of the tax liability
  • $10 to $2000 - $10
  • Above $2000 - the tax liability x .005, not to exceed $1000

Returns are due by the last day of the month following the end of the reporting period, with one exception. Early monthly sales tax filers must file by the 20th of the month following the end of the reporting period. A return must be filed even if no tax is due for that period.
