Instalment interest accrues, and a penalty applies once that interest exceeds the threshold in s. 163.1. The penalty is computed on the excess, not on the instalment.
File with Canada Revenue AgencyFrequently asked questions
- What happens if an instalment is missed?
- Instalment interest accrues, and a penalty is added once that interest exceeds the threshold in section 163.1. The penalty is computed on the excess, not on the instalment.
- Can instalments be stopped mid-year?
- Instalments follow a calculation method chosen at the start of the year. A drop in income does not automatically suspend the obligation: the chosen method determines the amount, and an insufficient payment produces interest.
