The Canada Revenue Agency confirmed the prescribed interest rate will hold at 3% for the fourth quarter of 2026, the sixth consecutive quarter at that level. The rate is set under section 4301 of the Income Tax Regulations from the average yield on three month Government of Canada Treasury Bills auctioned in the first month of the preceding quarter, rounded up to the next whole percentage point. That yield came in at 2.29% for Q4, comfortably inside the range that rounds up to 3%.
The rate on overdue tax balances stays at 7%, four percentage points above the prescribed rate as it always is. For advisors running prescribed rate loan strategies for clients, the number that matters has not moved since early 2025: six straight quarters at 3% is the longest stretch of stability this planning tool has had in several years.
The Income-Splitting Math Has Not Changed, and That Is the Point
A prescribed rate loan lets a higher income spouse or parent lend money to a lower income family member or a family trust at the prescribed rate, with the investment income taxed in the borrower's hands rather than the lender's. The strategy works best when the rate is low and stable, because the borrower needs to generate a return above 3% to make the arrangement worthwhile, and needs certainty that the rate will not reset higher partway through.
Six consecutive quarters at 3% is exactly that certainty. The annual interest payment deadline remains firm: interest must be paid by January 30 of the following year, or the loan's income attributes back to the lender for that year and every year after. That deadline does not move with the quarter's rate announcement, and it is the single most common point of failure in prescribed rate loan structures.
The Tariff Response Is the More Urgent Conversation for Business Owner Clients
Canada's counter-tariffs on a list of U.S. products, including steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics, take effect September 8. They match Washington's 50% levy on $20 billion of Canadian exports dollar for dollar, following Prime Minister Mark Carney's announcement that trade talks had collapsed over demands he called uneconomic and unfair.
Ottawa has responded with four named support programs carrying a combined $17.5 billion in commitments, ranging from a $10 billion large enterprise loan facility down to a $500 million liquidity stream aimed specifically at small and medium sized businesses.
Four federal programs announced in late August carry a combined $17.5 billion in commitments for tariff-affected workers and businesses. The $10 billion Large Enterprise Tariff Loan Facility had deployed roughly 5% of its capacity as of early September, split between loans to Algoma Steel and Arctic Canadian Diamond Company.
The Large Enterprise Tariff Loan Facility, administered by the Canada Enterprise Emergency Funding Corporation, has issued two loans so far: $400 million to Algoma Steel and $115 million to Arctic Canadian Diamond Company, together about 5% of the facility's total capacity. The Business Development Bank of Canada's Pivot to Grow stream lowered its minimum revenue eligibility to $1 million and is directing enhanced support toward forestry, steel and aluminum specifically.
What This Means for CCPC Clients in the Affected Sectors
A corporate client in steel, dairy processing, appliance manufacturing, agricultural equipment, pulp and paper, or electronics importing now has two separate planning threads running at once. The prescribed rate environment remains favourable for any income-splitting or estate freeze structure already in place. Nothing about the tariff announcement changes that math.
What has changed is the client's operating cost base and, for some, their eligibility for federal liquidity support. The Regional Tariff Response Initiative and the Canada Strong Diversification Fund both flow through Canada's regional development agencies rather than directly from Ottawa, a different application path than the one CRA or BDC relationships typically run through. The window between now and September 8 is narrow for any business owner confirming exposure before the tariffs take effect.
