TCC26-0019: CARM Late Payment Interest Calculation

In order to support the transition to the CBSA Assessment and Revenue Management (CARM) system, the CBSA in January 2025 put in place transition measures for late-payment interest as per Customs Notice 25-02.

Starting on January 31, late-payment penalties and late-payment interest will no longer be waived, and monthly calculation on unpaid debts such as duties, penalties and other amounts owing will resume. 

The late-payment interest will start accruing on accounts with an overdue balance as of January 31, and will be included on the Statement of Account to be issued on February 25.
