Six Quarters at 3 Percent, and the Window Is About to Close

Aug 25, 2026 6 min The Tax & Wealth Desk

The Brief

The CRA confirmed the prescribed rate holds at 3% for Q4 2026, the sixth straight quarter and the lowest sustained level since Q4 2022.
Canada's retaliatory tariffs take effect September 8 on US steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics.
CCPC owners in those same sectors face a fiscal year end window that closes alongside the tariff date, not in January.
Prescribed rate loans lock in today's rate for the life of the loan, even if the CRA rate rises afterward.
Short term Treasury bill yields, the basis for the prescribed rate, could move higher if tariff driven inflation persists into 2027.

The Canada Revenue Agency confirmed Monday that the prescribed rate will hold at 3 percent for the fourth quarter of 2026, the sixth consecutive quarter at that level and the lowest sustained reading since the final quarter of 2022. For a prescribed rate loan strategy, that stability is the entire trade.

A prescribed rate loan lets a higher income spouse, common-law partner or family trust lend to a lower income family member at the CRA rate in effect when the loan is made. As long as the borrower pays the interest within 30 days of each year end, that original rate locks in for the life of the loan, even if the CRA rate rises afterward.

Six Quarters at the Floor

The rate has fallen in a straight line since the second quarter of 2024: 6 percent, then 5 percent for two quarters, 4 percent for two more, and 3 percent for the six quarters running from the third quarter of 2025 through the fourth quarter of 2026. Every step down widened the spread between a locked in rate and whatever the borrowed funds can earn.

The prescribed rate history below tracks that descent, and the current 3 percent floor against the yield an invested loan can realistically target sets the size of the annual income split.

That spread is the entire mechanism. A family trust funded today at 3 percent and invested to a 6 percent return splits the 3 percentage point difference with beneficiaries in lower tax brackets, indefinitely, at the rate locked on the day the loan was made.

The Trade War Adds a Second Deadline

Canada's retaliatory tariffs take effect September 8 and target US steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics. For CCPC owners in those same six sectors on the Canadian side, input costs on any US sourced materials or equipment are about to move, and the planning window for this fiscal year is closing at the same time the prescribed rate window is.

Accelerating capital cost allowance claims on equipment purchased ahead of September 8, reviewing duty drawback eligibility on tariff affected inputs, and confirming SR&ED eligibility on any process changes made to reduce US sourced input reliance are fiscal year end conversations for incorporated clients in these sectors, not ones that can wait for January.

What the Rate Could Do Next

The prescribed rate is set from the average yield on 90 day Government of Canada Treasury bills auctioned in the first month of the preceding quarter, rounded up. Tariff driven inflation is exactly the kind of pressure that could push short term yields, and the prescribed rate with them, higher heading into the first quarter of 2027.

A loan structured before that happens locks in the current 3 percent rate for its full term regardless of where the rate goes afterward. A loan structured after a reset does not get the option back.

What They're Feeling

Incorporated clients in steel, dairy, appliance, agricultural equipment, pulp and paper, or electronics manufacturing are anxious about margin compression from the September 8 tariffs. Personal clients with existing or planned prescribed rate loans may not realize the rate's stability is temporary or that timing the loan matters.

What to Say

I want to flag two deadlines that are closing at the same time. If you're incorporated and your business touches steel, dairy, appliances, agricultural equipment, pulp and paper, or electronics, the September 8 tariffs change your input costs, and we should look at capital cost allowance and duty drawback options before then. Separately, if we've talked about a prescribed rate loan for income splitting, the rate has been flat at 3 percent for six quarters, which is the lowest it's been since 2022, and locking that in now protects you if it resets higher in the new year.

Who's Affected

High impact: CCPC owners with US sourced inputs or equipment in the six named tariff sectors, particularly those with a fiscal year end before December.

Mixed impact: Clients with existing prescribed rate loans already locked at 3 percent or lower, whose structure is unaffected either way.

Potential benefit: Clients who have discussed but not yet implemented a prescribed rate loan and can still lock in before any first quarter 2027 reset.

Action Checklist

Identify incorporated clients with exposure to the six September 8 tariff sectors

Review capital cost allowance acceleration options for equipment purchased before the tariff date

Flag prescribed rate loan candidates who have not yet locked in the current 3% rate

Confirm any existing prescribed rate loans have interest paid within 30 days of year end

Hi [Client Name],

Following up on our conversation about the September 8 tariffs and the prescribed rate. The rate has held at 3 percent for six straight quarters, the lowest sustained level since 2022, but that window may not last into the new year given the trade environment.

Let's set up time before year end to review both the tariff exposure and whether a prescribed rate loan makes sense to lock in now.

Client Profiles to Target

CCPC owners in tariff exposed sectors: Incorporated business owners in steel, dairy, appliances, agricultural equipment, pulp and paper, or electronics who may not have a current advisor reviewing their September 8 exposure.

High income individuals without an income splitting strategy: Professionals or business owners who have never set up a prescribed rate loan and are unaware the current rate is the lowest sustained level since 2022.

Family trust holders: Clients with existing trusts who have not revisited funding strategy since the rate began falling in 2024.

Opening Line

The CRA prescribed rate has been flat at 3 percent for six straight quarters, the lowest it's been since 2022, and that window may be closing given what's happening with tariffs and inflation. Do you have fifteen minutes to see whether that applies to you?

Value Proposition

Two planning windows are converging this fall. The prescribed rate has sat at its lowest sustained level in four years, which is the entire mechanism behind an income splitting loan, but short term Treasury bill yields could push it higher once tariff driven inflation from the September 8 retaliatory measures works through the data. Separately, incorporated clients in the six named tariff sectors have a fiscal year end planning window on capital cost allowance and duty drawback that most self directed business owners are not tracking closely.

An advisor's value here is connecting a rate environment most people are not watching to a deadline most business owners have not calendared.

Discovery Questions

Does your business source materials or equipment from the US in steel, dairy, appliances, agricultural equipment, pulp and paper, or electronics?

Have you ever used a prescribed rate loan to split investment income with a spouse or family trust?

When did you last review your corporation's capital cost allowance claims against planned equipment purchases?

Do you have a fiscal year end before December that would be affected by the September 8 tariff date?

Hi [Name],

The CRA's prescribed rate has been flat at 3 percent for six quarters, the lowest sustained level since 2022, and Canada's September 8 retaliatory tariffs are creating a separate deadline for business owners in six specific sectors. If either applies to you, it's worth a short conversation before year end.

Happy to walk through what I'm seeing with clients in a similar position.
