About CRA Prescribed Rates
The Canada Revenue Agency (CRA) sets prescribed interest rates quarterly. This calculator uses historical rates to compute compound daily interest on overdue tax debts.
Interest is calculated from the day after the initial due date until the payment date, compounding daily at the applicable prescribed rate for each period.
