## New Interest Rates — What It Means for Your Filing
CRA’s prescribed interest rates for Q2 2026 (April 1-June 30) are now in effect. Key rates include **7 %** on overdue taxes and contributions, **3 %** or **5 %** on overpayments depending on corporate or individual status, and **6.20 %** applicable to corporate indebtedness and interest-free/low-interest loans.

### Who is Most Affected?
- Individuals/investors with income tax or benefit balances owing will see interest charged at **7 %**, compounded daily.
- Corporations expecting refunds must note the **3 %** overpayment rate; non-corporate (individuals, trusts) see **5 %**. This can impact cash flow estimates.
- Employers/shareholders providing interest-free or low-interest loans will have to calculate taxable benefits using the **3 % rate**. In cross-period arrangements, watch for CRA’s definitions of "pertinent indebtedness."

## First-Time Home Buyers’ GST/HST Rebate under Bill C-4
The new First-Time Home Buyers’ GST rebate introduced by Bill C-4 removes GST entirely on new homes priced up to \$1 million for first-time buyers, and reduces GST for homes between \$1 million and \$1.5 million. Agreements of purchase must be entered into **on or after March 20, 2025 and before 2031** for eligibility.

### Compliance Tips
- Ensure you maintain records of purchase agreements, dates, and construction details to prove eligibility.
- If building or buying a condominium or substantially renovated home, confirm whether substantial renovation rules are satisfied.
- Use GST/HST rebate forms correctly; misreporting taxable acquisition prices can delay or reduce benefit.

## Example Scenario
Sarah is a first-time home buyer who enters into a contract on August 1, 2025 to purchase a newly built home costing \$1,200,000. Under the new rebate rules:
- Since purchase is between \$1 million and \$1.5 million, she cannot eliminate GST fully but will receive a reduced rate rebate.
- She should submit the GST rebate claim with purchase agreement and construction documents.
- If she had overpaid her taxes last year, she will receive **5 % interest** on overpayments.
- If she owed taxes, the amount overdue will carry **7 % interest**, so paying on time or making instalments is important.

## Action Checklist
- Review Q2 2026 prescribed interest rates and adjust your cash-flow forecasts accordingly.
- For first-time home buyers, check eligibility under the new GST rebate rules; ensure accurate documentation.
- Update your accounting system or software to reflect the 14 % base rate, new rebate rules, and interest rates.
- Consult tax advisor if you have cross-jurisdictional income, foreign property, or significant capital gains to understand interaction with rate changes.
**Key takeaway**: The interest rate changes and the GST rebate transition create both filings and documentation obligations. Staying ahead ensures maximizing benefits and avoiding unnecessary charges.
