## Q3 2026 Prescribed Interest Rates & Why They Matter
The CRA’s prescribed rates effective **July 1 to September 30, 2026** are:
- **7%** interest charged on overdue taxes, CPP contributions, and EI premiums.
- Refunds to corporate taxpayers: **3%**, to non-corporate taxpayers: **5%**.
- Employee/shareholder low-interest loans taxed at **3%**; corporate debt or indebtedness: **6.30%**. ([canada.ca](https://www.canada.ca/en/revenue-agency/services/tax/prescribed-interest-rates/2026-q3.html?utm_source=openai))
Compliance impact:
- Delaying payments or disputing assessments comes at a cost—at 7%, interest on overdue amounts compounds fast.
- Passive income, shareholder loans could be taxed if the interest falls below the prescribed rate.
## Provincial Payroll Tax Updates
- **British Columbia** increased its lowest personal tax rate from **5.06% to 5.60%** for 2026. Their “basic reduction” increased from \$562 to \$690. Payroll software now needs to apply prorated amounts for post-July 1 pay.

- **Newfoundland and Labrador** updated its Basic Personal Amount (BPA) to **\$13,094**, effective January 1, 2026. Employers must reflect this in source deductions.

- **Prince Edward Island** introduced a new bracket above **\$200,000** taxable income at **20%** for 2026, changing how high earners are taxed at source.

## Anti-Avoidance and RRSP/RRIF Rules (Existing / Ongoing)
Canada’s anti-avoidance rules impose special taxes on:
- **Non-qualified or prohibited investments** held within RRSPs or RRIFs.
- **Advantages**, including below-market loans or benefits, extensions of credit, debts.
- Procedures exist to request waivers or cancellations in certain cases. ([canada.ca](https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/anti-avoidance-rules-rrsps-rrifs.html?utm_source=openai))
Practical compliance steps:
- Keep schedules and documentation for all RRSP/ RRIF investments; check if any investments could be non-qualified or prohibited.
- For shareholder or employee loans, ensure interest is at or above prescribed rate to avoid benefit inclusion.
## Action Plan for Businesses & Tax Professionals
- Update payroll processing systems **post-July 1, 2026** to reflect new provincial rates and amounts.
- Review any outstanding liabilities or slow-pay situations for individuals or corporations—interest could significantly increase tax owing.
- Audits should focus on share-holder/employee loan agreements and RRSP/ RRIF plan investment structures.
By staying ahead of these rates, businesses and individuals can mitigate unexpected tax hits and ensure all source deductions and credits are calculated correctly.
