Filing frequencies & due dates

Filing frequencies

After you registered your business, we sent you a packet of information. In this packet there is a welcome letter with your:

  • Account ID
  • Filing frequency (monthly, quarterly, annual)

Filing frequencies are assigned based on what you estimate for your yearly business income.


Due dates

  • Monthly returns are due the 25th of every month. (e.g. The June tax return is due July 25.)
  • Quarterly returns are due the end of the month following the tax quarter. (e.g. The Quarter 1 (Jan, Feb, Mar) tax return is due April 30.)
  • Annual returns are due April 15. (e.g. The Annual 2019 tax return is due April 15, 2020)

If the due date falls on a weekend or legal holiday, the due date is extended to the next business day.
