Overview of CRA’s Q3 2026 Prescribed Rates
From July 1 to September 30, 2026, the Canada Revenue Agency has set the following prescribed annual interest rates: (canada.ca)
| Type of Amount | Overdue by Taxpayer / Remittances | Overpayment Rates |
|---|---|---|
| Overdue taxes / CPP / EI premiums | 7% | — |
| Corporate taxpayer overpayments | — | 3% |
| Non-corporate taxpayer overpayments | — | 5% |
| Taxable benefits from employee/shareholder loans | — | 3% |
| Corporate loans / indebtedness | — | 6.30% |
Why These Rates Matter
- Individual taxpayers who overpay (e.g., too much tax withheld) will receive only 5% annually. Yet, if you owe tax, interest is a hefty 7%. Planning to reduce overpayment may make sense.
- Corporations face only 3% on overpayments but must pay 7% if overdue — watch cash flow and remittances carefully.
- For any low or interest-free loan from employer/shareholder, the benefit gets taxed using a 3% rate — important in benefits planning.
Planning Action Points
- Time your payments. If you expect to owe, paying before this quarter begins (or arranging payments) can reduce costly interest.
- Claiming refunds: File as soon as possible if you have overpayments — you only accumulate 5% instead of losing value waiting.
- Monitor loans or advances arranged for employees: ensure any interest or benefit calculations use the 3% rule.
- For corporations incurring debt, consider if refinancing can reduce interest-bearing load given the 6.30% rate.
Example Scenarios
- Freelancer Alice overpaid her 2025 taxes by $1,000; from July to filing, she’ll receive 5% interest but if she owes instead, her cost is 7%.
- CorpX has overdue GST remittances; effective interest is 7%, so delaying carries real cost.
- Employ-ee loan of $10,000 interest-free: taxable benefit will use prescribed 3% rate — adding $300 in taxable employment income.
Tips for Tax-Smart Choices
- Keep close tabs on filing deadlines and remittance dates.
- Use tax instalments wisely to avoid overpayment while also avoiding penalties.
- Records for employment-loan benefits should be maintained carefully—CRA may audit.
- When possible, align corporate spending or debt structuring in favor of lower interest obligations.
These prescribed rates are automatic and apply across various tax categories — understanding them gives you better control over tax timing and cash flow.
