Source Deductions Penalties & Payments

Since July 2003, the Canada Revenue Agency (CRA) has administratively applied a graduated penalty structure to late remittances rather than the legislated 10% penalty. This administrative position applied to remittances of source deductions under Part I of the Income Tax Act. The February 26, 2008 budget proposes to legislate the graduated penalty structure. Non-resident tax remittances under Part XIII of the Act will also be subject to the graduated penalty structure as of February 26, 2008.

3% of the amount if received one to three days after it was due.
5% of the amount if received four or five days after it was due.
7% of the amount if received six or seven days after it was due.
10% of the amount if not paid or received on or before the seventh day after it as due.
Large employers with an average monthly withholding amount of $50,000 or more are required to remit their deductions at source at a designated financial institution (DFI). Failure to comply with this requirement could result in a penalty of 10% of the amount not remitted at a DFI.
