## Understanding the Tax Cut and the Top-Up Tax Credit Canada’s federal government reduced the **lowest marginal personal income tax rate** from **15 %** to **14 %** starting **July 1, 2025**. For 2025, because the change takes effect halfway through the year, the full-year rate is **14.5 %**, and for **2026 and beyond**, it will be 14 %. ([canada.ca](https://www.canada.ca/en/department-finance/corporate/transparency/2025/senate-cow-c4-2025-06-17.html?utm_source=openai)) Simultaneously, as many non-refundable tax credits are scaled by the lowest tax rate, some taxpayers with large deductions (medical, tuition, etc.) may lose money under the new lower rate. To prevent this, the government has proposed a **Top-Up Tax Credit** (effective 2025-2030) to maintain the previous 15 % rate for non-refundable credits in excess of the first bracket threshold (≈ $57,375 in 2025) for eligible individuals. ([canada.ca](https://www.canada.ca/content/dam/cra-arc/migration/cra-arc/tx/bsnss/tpcs/pyrll/t4032/2026/t4032-on-1-26e.pdf?utm_source=openai)) ## Actionable Planning Tips for 2025-2026 1. **Estimate your non-refundable credits** this year (tuition, medical, donations etc.). If you expect large amounts above $57,375, the Top-Up Tax Credit will help—but you’ll need to be sure to claim them properly. 2. **Adjust payroll withholdings**: Because withholding rates will change mid-year, your pay stub might show less tax withheld after July 1, 2025. If you expect large income or credit claims late in the year (e.g. stock options exercise, capital gains), review withholding or make instalments to prevent underpayment penalties. 3. **Optimize timing of expenses**: If you have large deductible expenses, consider whether incurring them late in 2025 vs early 2026 can affect your benefit under these rules. The Top-Up Credit applies only if credits exceed the threshold, so moving expenses could change whether you “cross” that threshold. 4. **Use high-income years strategically**: If you anticipate a year where many non-refundable credits will be large (e.g. pursuing higher education, major healthcare expenses), ensure you benefit from them fully—keep good documentation and file earlier to adjust expectations. ## Example Scenario - Jane has taxable income of $60,000 in 2025. She has $70,000 worth of non-refundable credits (tuition, medical, etc.). - With old rate (15 %), she’d get value of 15 % × $70,000 = **$10,500**. - With the new rate mid-year, the lowest rate “costs” is lower (say, 14.5 %), so she’d get 14.5 % × (first $57,375) + 14 % × (amount over threshold). Without Top-Up Credit, she may lose several hundred dollars in credit value. - With the proposed Top-Up Credit, she can preserve much or all of that value for amounts above the threshold. ## What to Watch For - **Legislation passing**: While Bill C-4 proposes related changes, the Top-Up Credit must become law. - **Income thresholds indexed annually**: What applies in 2025 may not match 2026. - **Provincial interaction**: Provincial tax rates and credits often use federal rates or link to federal rules; changes federally can cascade or affect provincial benefits. ## Key Takeaways - The low rate cut is real—£you’ll likely see some tax savings automatically in paycheque withholding or simple calculations. - But if you normally rely on large non-refundable tax credits, keep an eye on the proposed Top-Up Credit and whether your credit amounts exceed thresholds. - Proper timing of deductions or expenses, and consulting with a tax adviser earlier in the year, can help maximize benefit under the new regime.
