## What changed under the tax cuts
Canada’s **Bill C-4**, Making Life More Affordable, **reduced the lowest federal personal income tax rate** from **15 % to 14.5 % for tax year 2025**, and to **14 % starting in 2026**, benefitting nearly **22 million Canadians**. ([canada.ca](https://www.canada.ca/en/department-finance/services/publications/report-impact-reducing-lowest-marginal-personal-income-tax-rate-non-refundable-tax-credits.html?utm_source=openai)) This change lowers federal tax payable, shifts value of non-refundable credits, and intertwines with use-of-bracket income thresholds.
Non-refundable credits (e.g. tuition, donations, medical) are now multiplied by the lower percentage, which can **reduce the benefit of these credits**. To offset this for those whose taxable income exceeds the first bracket threshold, a **Top-Up Tax Credit** was introduced to maintain earlier benefits.

## Planning strategies in light of these changes
- **Stack non-refundable credits** earlier in the year: because lower rate reduces benefit for large claims late in the bracket hierarchy. If possible, make donations or prepay eligible expenses when taxable income remains in the lowest bracket.
- **Track income flows carefully**: a big bonus or stock sale moves you into higher brackets sooner, reducing marginal benefits.
- **Use the Top-Up Tax Credit**: ensure you understand whether you're eligible. If your non-refundable credit amounts (beyond the first bracket threshold) are high, this credit mitigates lost value.
## Example
Imagine Alice has taxable income of $70,000 in 2026. The first $58,523 is taxed at 14 %, the remainder at 20.5%. Previously credits were valued at 15 % for entire first bracket; now only 14 %. She has $5,000 in charitable donations: that credit is now worth $700 instead of $750. But with the Top-Up Tax Credit, she may recoup some of the difference, depending on structure.
## Actionable steps to benefit
1. Calculate your expected taxable income early—the phase-in of the lower rate means timing of income matters.
2. If you’ll exceed the first bracket, plan credit claims that stretch over periods when you’re in lower brackets.
3. Consult a tax professional or use CRA tools to model your 2026 tax to see gains from the rate cut versus losses in credit value.
4. Update withholding and instalment payments; with rate changes, you may owe more/less in instalments.
Canada’s tax landscape has shifted under Bill C-4—while most see net benefit, savvy planning will help you maximize savings and avoid surprises.
