The Canada Revenue Agency prescribed rate is 3% for the fourth quarter of 2026, its sixth consecutive quarter at that level. A loan made between now and December 31 keeps 3% for as long as it stays outstanding and the interest is paid on time. The more useful number for planning is 2.39%, the three-month Government of Canada T-bill yield on October 7 according to Bank of Canada data, because October auctions set the Q1 2027 rate.

The rate is the average three-month T-bill yield from the first month of the preceding quarter, rounded up to the next whole percentage. July auctions averaged 2.29%, which produced 3% for Q4. A reading of 2.39% leaves 0.61 percentage points before the average would pass 3.00% and push the rate to 4%.

The Cushion Is Real, and the Yield Curve Says It Is Finite

The Bank of Canada held its overnight rate at 2.25% on September 2. The market is pricing something different further out. The Government of Canada two-year yield was 3.25% on October 8, according to Trading Economics, 0.86 percentage points above the T-bill. The five-year yield was 3.60% and the ten-year yield 3.93%.

A two-year yield above 3.00% does not mean the Q1 2027 rate moves. October T-bill yields would need to average above 3.00% for that, and the latest readings are 2.39%. It does mean a prescribed rate of 4% becomes a live possibility for a later quarter if the Bank of Canada follows the path the bond market describes.

The prescribed rate has fallen from 6% in the first half of 2024 to 3%, where it has stayed for six quarters, and the October T-bill sits 0.61 points below the level that would lift it to 4%.

The prescribed rate is the average yield on three-month Government of Canada T-bills auctioned in the first month of the preceding quarter, rounded up to the next whole percentage. The Q1 2027 rate will be set from October 2026 auctions.

What a Q4 Loan Locks and What It Requires

A loan made at the prescribed rate to a spouse, common-law partner, family member or family trust shifts investment income from the lender to a family member in a lower tax bracket, without triggering attribution, if two conditions hold. The rate on the promissory note must be at least the prescribed rate in effect when the loan was made, and the interest for each calendar year must actually be paid by January 30 of the following year.

For a loan made in Q4 2026, the first payment covers the period to December 31 and is due January 30, 2027, 113 days from today. If a payment is missed, the investment income is attributed back to the lender for that year and for all later years. TaxTips.ca also notes that the interest should be paid by the borrowing spouse, with records that make the payer clear, and that joint accounts can cause problems.

Why the Hurdle Is Lower Than It Looks

A $400,000 loan at 3% carries $12,000 of annual interest. The borrowing spouse deducts it and the lender reports it. Every percentage point the borrowed money earns above 3%, or $4,000 on $400,000, is taxed at the marginal rate of the borrowing spouse. A Government of Canada five-year bond yielding 3.60% would clear the hurdle by 0.60 points, or $2,400 a year before tax, so covering the cost does not require a risky portfolio.

Existing loans keep the rate in force when they were made, which means loans made from the third quarter of 2023 through the fourth quarter of 2024 carry 5% or 6% for their remaining life. TaxTips.ca notes that refinancing a higher-rate loan at the current rate would likely trigger attribution, so the 3% rate is available only to new loans.

Which Accounts Fit and Which Do Not

The loan strategy applies to non-registered money held in a separate account in the name of the borrowing spouse. TFSA and RRSP room comes first in most household plans because income inside those accounts is sheltered. Gifts from a spouse to fund a TFSA contribution do not attract attribution on the income earned inside the account. A spousal RRSP produces a related result through a different mechanism, a three-calendar-year attribution window on withdrawals.

For money that is already outside registered accounts, the prescribed rate loan is the remaining tool, and a family trust that distributes to lower-bracket family members is the structure used where several beneficiaries are involved. The planning deadlines are December 31 for the loan to be made at the Q4 rate and January 30, 2027 for the first interest payment. The Q1 2027 rate should be confirmed once the October auctions are complete.
