The Canada Revenue Agency (CRA) will charge 9% interest on late payments in the fourth quarter, the same rate it is charging through the third quarter of this year.
The rate charged on overdue tax is set four percentage points higher than the prescribed rate on family loans.
Based on Government of Canada three-month Treasury Bill yields through July, the prescribed interest rate used for loans to family members will remain 5% in the fourth quarter.
The CRA charged 10% interest on overdue taxes through the first half of 2024, up from 9% in the fourth quarter of 2023.
Prescribed interest rates began rising in the third quarter of 2022 as a result of the increasing rate of inflation. Before then, the prescribed rate for loans to family members had been 1%, and the rate charged on overdue tax was 5%, for two years.
The CRA charges interest, compounded daily, on overdue taxes. The interest the CRA charges on an overdue amount over time will reflect the prescribed rates for each quarter over that period. The CRA may also impose penalties, for example, for late filing, as well as interest on the penalties.
Prescribed-rate loans
Prescribed-rate loans can be used to split investment income with a spouse, common-law partner or other family member. However, as the prescribed rate rises, so too must the expected investment return to make the strategy viable.
Loans could be made directly to a family member or to a family trust, which can then make distributions to family members in low tax brackets as part of a properly executed prescribed-rate loan strategy.
As long as annual interest is paid within 30 days of year-end, the loan can remain in effect at the prescribed rate that was current when the loan was originally made. Failure to pay by the deadline will result in any investment income earned on the loan being attributed back to the lender for the year the interest was incurred — and all subsequent years.
Why the prescribed rate is holding steady
The prescribed rate is calculated every quarter.
According to Section 4301 of the Income Tax Regulations, the prescribed rate is based on the average yield of Government of Canada three-month Treasury Bills auctioned in the first month of the preceding quarter, rounded up to the next whole percentage.
The auction yields for three-month T-Bills were 4.65% on July 2, 4.54% on July 16 and 4.41% on July 30. As the average of those three yields is 4.53%, the prescribed rate will be 5% for the fourth quarter of 2024.
