The Canada Revenue Agency confirmed Tuesday that the prescribed rate will hold at 3% for the third quarter of 2026, covering loans made or outstanding from July 1 through September 30. It is the fifth straight quarter at that level, following a steady decline from the 6% peak reached in early 2024.
For advisors with incorporated business owner clients or households with a significant income gap between spouses, that number is the planning variable behind one of the more durable income-splitting tools in the Income Tax Act. The window it opens is real. It is also more exposed to today's Fed tone than most clients realize.
How the Rate Connects to This Afternoon's Fed Decision
The prescribed rate is not set by discretion. Section 4301 of the Income Tax Regulations ties it to the average yield on 90-day Government of Canada Treasury bills over the first month of the preceding quarter, rounded up to the next whole percentage point. The Q3 2026 rate was locked in using May data, before this week's developments.
The Fed held its policy rate at 3.50% to 3.75% Wednesday, in line with expectations, but the updated dot plot showed several officials now projecting a 2026 hike rather than the cut markets had priced as recently as March. The two-year US Treasury yield moved higher within minutes of the release. Government of Canada yields tend to track US Treasuries with a lag, not a one-to-one correlation, but a sustained firmer tone out of Washington is the kind of input that can lift the 90-day T-bill average the CRA will use to calculate the Q4 rate this coming September.
That matters less for understanding today's number and more for understanding the planning window around it. A prescribed rate loan locks in its rate at the date the loan is advanced, for the life of the loan, regardless of what the rate does afterward. A client who sets up the loan in July at 3% keeps that rate even if the September announcement moves Q4 to 4%.
The Mechanics for a Business Owner Client
The structure is straightforward but the documentation discipline is not optional. The higher income spouse, or the corporation, lends funds to the lower income spouse or an adult family member at the prescribed rate in effect when the loan is advanced. The borrower invests the funds, and any income or capital gain on the investment is taxed in the borrower's hands at their lower marginal rate, not the lender's.
The borrower must pay the lender interest at the prescribed rate annually, and that payment must arrive no later than January 30 of the following year. There is no partial credit for late payment. Missing the deadline by even a few days converts the entire year's investment income back to the lender under the attribution rules, eliminating the benefit retroactively for that tax year.
For incorporated business owner clients, the same mechanism works through corporate-shareholder loans under section 80.4, with the taxable benefit calculated as the prescribed rate less whatever interest was actually paid. At 3%, a $200,000 loan that goes unpaid for a full year generates a $6,000 taxable benefit to the shareholder, a number worth running explicitly rather than leaving as an abstraction.
Why the Conversation Belongs in July, Not September
Clients planning to use this structure face an asymmetric calendar. Waiting to see whether the Q4 rate moves costs nothing if it stays flat, but forecloses the lower rate entirely if it rises, since the rate locked in is whatever applies on the date the loan is actually advanced, not the date the conversation happens.
The prescribed rate has now sat at or below 3% for five straight quarters, the longest stretch this low since before the 2022 to 2024 tightening cycle. WTI crude's recent slide following the prospective US-Iran settlement had been easing inflation pressure into the spring T-bill data. A firmer Fed tone working through bond markets over the next several weeks is the more proximate risk to that streak continuing into Q4.
The rate's path from its 2024 peak to the current five-quarter plateau shows how unusual the present window is against recent history, and how much room exists for it to move once T-bill yields respond to a shift like today's.
The rate fell from 6% in early 2024 to 3% by the third quarter of 2025 and has held there for five consecutive quarters. Each step down reflects the 90-day T-bill average from the prior quarter's first month.
