## What changed
Bill C-4, known as the *Making Life More Affordable for Canadians Act*, has enacted a reduction of the first marginal personal income tax rate from **15 % to 14 %**, effective **July 1, 2025**. Because this change takes effect halfway through the 2025 taxation year, the **full-year rate for 2025 is 14.5 %**, going to 14 % for 2026 and beyond.

## How this affects tax planning for individuals
- **Target deductions and income timing**: If you have income in the lowest bracket (below ~$58,523 for 2026), defer income to after mid-2025 only if it brings you into a higher bracket; you’ll save more by shifting deductible expenses into 2025 *before* July 1 when marginal rate remains higher.
- **Non-refundable tax credits**: Since these are valued at the lowest rate, credits like the basic personal amount get more value under 14 %. If you’re in a situation where these credits are taxed at 15 % previously, expect savings.

- **Two-income families**: Because both spouses may benefit from the rate cut, the cumulative savings for households can be **up to $840 annually** once the full-year rate of 14 % kicks in.

## Actionable strategies
| Strategy | What to do | Why it helps |
|---|---|---|
| Accelerate deductions into early 2025 | Prepay allowable expenses (medical, charitable, tuition) before year end if near bracket thresholds | Helps reduce taxable income taxed at 14.5 % instead of a higher bracket |
| Maximize non-refundable credits | Claim all available credits since their value increases with the lower rate | Credits offer more benefit when multiplied by a lower bracket rate |
| Review investment income | Ensure capital gains are realized in tax years where inclusion rate and thresholds work in your favour | Particularly relevant if other changes (proposed) occur later |
## Examples
- **Example 1**: Jane earns $50,000 in employment income. Under 15 %, her tax in the first half of 2025 is higher. With bracket reduction, she saves proportionally on income from July 1 onward. If she has a $1,000 non-refundable credit (e.g., donations), its value rises from ~$150 to ~$140—i.e., she pays less tax.
- **Example 2**: Mark and Maria, both earning taxable incomes in the first bracket, will benefit approximately $420 per person annually once the full year reaches 14 %. Together, they could save ~$840. ([canada.ca](https://www.canada.ca/en/department-finance/news/2026/03/legislation-to-make-life-more-affordable-receives-royal-assent.html?utm_source=openai))
## What to watch out for
- **Software and withholding adjustments** may lag. For some employers, payroll withholding at 14 % may not be implemented immediately; some refunds or adjustments happen at filing time.

- Proposed changes to other tax policy (capital gains, lifetime exemptions, etc.) are still under consultation or legislative process. Keep an eye on those before making large investment decisions.
## Bottom line
The reduction in the lowest federal tax rate is one of the most impactful affordability measures recently enacted. Especially for low- and middle-income Canadians, the savings are real—but strategic planning around deductibles, credits, and timing can help extract maximum benefit. Stay updated on proposed changes too, as combined effects could shift your tax outcome further.
