Shareholder Loans and CRA Rules in 2026: What Every Canadian Business Owner Needs to Know

Shareholder loans are one of the most common tools owner-managers use to move money between themselves and their corporations — and one of the most frequently reviewed areas in a CRA audit. The rules under subsection 15(2) of the Income Tax Act are unforgiving: borrow from your company, fail to repay inside the prescribed window, and the full amount is added to your personal income for the year the loan was made.

There is a second rule that catches far more owner-managers than the first, and it applies even when the loan is repaid on time: the section 80.4 taxable benefit on interest-free and low-interest loans. That benefit is measured against the CRA prescribed rate, which is reset every quarter. This guide states the current rate, shows the arithmetic, and sets out the documentation that survives an audit.

What is the shareholder loan repayment rule under CRA?

Under subsection 15(2), a loan from a corporation to a shareholder must be repaid by the end of the corporation’s taxation year following the year in which the loan was made. If a loan was advanced in the fiscal year ending December 31, 2025, it must be repaid by December 31, 2026. Miss that date and the full principal is included in the shareholder’s income for 2025 — the year the loan was made, not the year the deadline was missed. That retroactive character is what makes the rule expensive: by the time CRA raises it on assessment, the 2025 return is already filed, and arrears interest runs from the original balance-due date at the overdue rate, 7% for the fourth quarter of 2026.

A repayment made after the deadline does not undo the inclusion. Subsection 20(1)(j) instead gives a deduction in the year of repayment, which produces a timing mismatch: income in one year, deduction in a later one, with the cash cost of the tax and interest borne in between. The statutory text is in the consolidated Income Tax Act, section 15.

What interest rate must a corporation charge on a shareholder loan in 2026?

The benchmark is the CRA prescribed rate, and the figure that matters for shareholder loans is the rate used to calculate taxable benefits on interest-free and low-interest loans. For the fourth quarter of 2026 — October 1 to December 31, 2026 — that rate is 3%. It is unchanged from the third quarter. Owner-managers who set their loan interest at 3% in July do not need to reprice in October.

Note that this 3% figure is the taxable benefit rate. It is not the rate CRA pays on a personal tax refund, which is 5% for non-corporate taxpayers. Conflating the two is a common error.

CRA prescribed annual interest rates — Q3 2026 vs Q4 2026

Rate	Q3 2026 (Jul 1 – Sep 30)	Q4 2026 (Oct 1 – Dec 31)	Change
Taxable benefit on interest-free / low-interest employee and shareholder loans (s. 80.4)	3%	3%	No change
Overdue taxes, CPP contributions, EI premiums	7%	7%	No change
Overpayments — corporate taxpayers	3%	3%	No change
Overpayments — non-corporate taxpayers	5%	5%	No change
Corporate pertinent loans or indebtedness (PLOI)	6.30%	6.29%	Down 0.01

How is the section 80.4 taxable benefit actually calculated?

The benefit is the prescribed-rate interest on the outstanding balance for the period the loan is outstanding, less any interest the shareholder actually pays in the year or within 30 days after year end. Because the prescribed rate is set quarterly, the calculation is done quarter by quarter and summed.

Worked example. An Ontario corporation advances a $100,000 interest-free loan to its sole shareholder. The loan is outstanding for the whole of the fourth quarter of 2026 — 92 days, October 1 to December 31 — at the Q4 prescribed rate of 3%:

Section 80.4 benefit — $100,000 interest-free loan, Q4 2026

Loan principal outstanding	$100,000
Q4 2026 prescribed benefit rate	3%
Days outstanding in the quarter	92
Benefit: $100,000 × 3% × 92 ÷ 365	$756
Less interest actually paid by January 30, 2027	($756)
Net taxable benefit	Nil

Two details decide the outcome. First, the interest must be actually paid, not merely accrued or booked to the loan account — and paid no later than January 30 of the following year. A journal entry on December 31 that is never funded does not count. Second, the benefit is an income inclusion under section 80.4, deemed to be interest — it is not a deduction to the corporation, so an interest-free loan is a genuine cost, not a wash. CRA sets out its administrative position in the Employers’ Guide – Taxable Benefits and Allowances (T4130), and the statutory rule is at Income Tax Act section 80.4.

What are the exceptions to the shareholder loan income inclusion rule?

Three exceptions sit in subsection 15(2.4). Each requires that bona fide repayment arrangements be documented at the time the loan is made — not reconstructed afterwards when CRA asks.

• Home purchase loans — to acquire a dwelling for the shareholder’s own occupation.
• Automobile loans — to purchase a motor vehicle used in the duties of employment of a shareholder-employee.
• Treasury share purchase loans — to acquire previously unissued shares from the corporation.

A critical qualifier is often missed: the exceptions generally require the loan to be received by virtue of employment rather than by virtue of shareholdings. A sole shareholder who draws no salary and performs no employment duties is on weak ground arguing the employment-based exceptions. Where the corporation has several shareholders and the loan terms are offered only to one, CRA will test whether the loan was really made in a shareholder capacity.

Note also that escaping the s. 15(2) principal inclusion does not escape s. 80.4. A qualifying home purchase loan still generates an interest benefit if it carries no interest — the two rules operate independently.

What happens if a shareholder repays and re-borrows repeatedly?

CRA looks through a series of loans and repayments designed to reset the one-year clock. Subsection 15(2.6) denies the repayment exception where the repayment forms part of a series of loans or other transactions and repayments. In practice the pattern that draws attention is a balance repaid days before the deadline and re-advanced days after it, with no change in the underlying economics.

What defends the position is evidence that each repayment was genuine and independently funded — a dividend actually declared and paid, a bonus run through payroll with source deductions remitted, or personal funds traceable to a non-corporate source. A repayment funded by a fresh advance from the same corporation is not a repayment in substance.

How should a shareholder loan be documented to survive a CRA audit?

The shareholder loan account is one of the first balances a CRA auditor asks for, because it is where personal spending tends to accumulate. Five items carry the file:

1. A written loan agreement executed at inception, stating principal, interest rate, repayment terms and security.
2. A director resolution authorizing the advance.
3. Balance sheet recognition as a receivable, reconciled at each year-end rather than at assessment.
4. Actual interest payments funded and cleared by January 30 of the following year.
5. A running shareholder loan ledger that separates genuine loans from expense reimbursements and personal draws.

The single most common bookkeeping failure is a shareholder loan account used as a catch-all suspense account. Personal purchases posted there through the year create a debit balance nobody intended to be a loan, and it is that unintended balance — not a deliberate advance — that usually triggers the subsection 15(2) assessment. Reviewing the account quarterly rather than annually keeps the balance small enough to clear before a deadline arrives.

Can a shareholder loan be converted to salary or dividends to avoid income inclusion?

Yes. If a bonus or dividend is declared and properly documented before the repayment deadline, it can be applied against the loan balance and the s. 15(2) inclusion is avoided. The remuneration is of course taxable in the shareholder’s hands — but that is a single layer of tax at a known rate, rather than a full principal inclusion plus arrears interest at 7% and a possible gross negligence exposure.

Which route is cheaper is a live calculation, not a rule of thumb. Salary creates RRSP room and CPP pensionable earnings and is deductible to the corporation; dividends are not deductible but avoid payroll remittances. The Ontario corporate rate that feeds the comparison is published at ontario.ca — Corporate Income Tax.

What are the most common shareholder loan mistakes?

• Treating the deadline as one year from the advance. It is the end of the taxation year following the year of the loan — which can be up to 24 months, or as little as 12, depending on when in the year the money moved.
• Accruing interest instead of paying it. The January 30 payment test is a cash test.
• Assuming a repaid loan carries no cost. Section 80.4 applies to the period the loan was outstanding regardless of eventual repayment.
• Using the refund interest rate. The shareholder benefit rate for Q4 2026 is 3%, not the 5% non-corporate overpayment rate.

When should an owner-manager review the loan account?

Before year-end, not after. Once the corporation’s year-end passes, the options narrow to repayment or an income inclusion; before it, a dividend or bonus can still be declared, a repayment schedule can still be documented, and interest can still be paid inside the January 30 window. For a December 31 year-end, the practical review date is late November — early enough to fund a repayment, declare a dividend, or reprice the loan to the prescribed rate.

The prescribed rate is republished each quarter, so a loan intended to sit outstanding across several quarters should be checked against the CRA prescribed interest rates index at each quarter boundary.
