Required tax instalments - Personal income tax

You may be looking for:

Tax instalments are payments you make throughout the year to cover the taxes you would normally pay in one lump sum on April 30 of the following year. This is similar to how an employer would deduct income taxes from each pay period throughout the year.

You may have to pay tax instalments for next year's taxes, if your net tax owing is more than $3,000 (for Quebec $1,800) for 2021 and in either 2020 or 2019.

Tax instalment payments are due by the following dates (except farmers and fishers who pay once on December 31):

  • March 15
  • June 15
  • September 15
  • December 15
