Taxpayers only have until December 31, 2021 to make a taxpayer relief request related to 2011. The deadline applies to taxpayers who intend to make relief requests relating to the 2011 tax year, any reporting period that ended during the 2011 calendar year, and any interest that accrued during the 2011 calendar year for any tax year or reporting period.

To avoid missing this 10-year deadline, taxpayers should consider making a protective request for potential relief during any stage in a CRA assessment or reassessment process (e.g., when a taxpayer requests an adjustment, or at the audit defense or notice of objection stages).


Under the taxpayer relief provisions in the Income Tax Act, the CRA has the discretion to:

  • Cancel or waive penalties and interest when taxpayers are unable to meet their tax obligations due to circumstances beyond their control
  • Accept certain late-filed, amended, or revoked income tax elections
  • Issue income tax refunds or reduce income tax payable beyond the normal three-year reassessment period (only for individuals and testamentary trusts [starting in 2016, only for individuals and graduated rate estates]).

This discretion is limited to tax years that ended within the 10 calendar years immediately before the calendar year in which a request is made.

The CRA also has the discretion to cancel or waive interest and certain penalties under the taxpayer relief provisions of the Excise Tax Act. This discretion is similarly limited to reporting periods that ended within the last 10 calendar years before the year in which a request is made.
