## What the Rate Change Is
Bill C-4 (Making Life More Affordable for Canadians Act), which received Royal Assent on **March 12, 2026**, reduced the lowest personal income tax rate: from **15% to 14%** effective **July 1, 2025**, with a transitional 14.5% rate for the full 2025 year.

## Who Benefits Most & When
- Roughly **22 million Canadians** benefit, especially those in the **first two tax brackets**, under $117,045 of taxable income. ([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))
- Those whose income is in the **lowest bracket** (under $58,523 in 2026) see most immediate benefit since the first rate applies to all income up to that threshold.

## Implications for Non-Refundable Tax Credits & Benefits
- Credits like the Basic Personal Amount, age amount, income‐tested benefits may be **less valuable** because the rate used to calculate non-refundable credits depends on the lowest marginal rate. With that reduced, some credits yield less tax reduction.

- Paychecks may get a small increase due to lower withholding for income in the first bracket—but final impact depends on your total taxable income.
## What to Do About It: Tax Planning Moves
- Review withholding in your payroll or adjust TD1 forms so you aren’t overpaying in the first bracket.
- For those expecting to have income that moves across brackets, compare year-end tax liabilities to ensure correct planning (e.g. splitting income, RRSP contributions, etc.).
- If you were relying heavily on non-refundable credits, recalculate current benefit entitlements (GST/HST credit, Canada Child Benefit) to see if adjustments are needed.
## Compliance and Reporting Notes
- Ensure your withholding rates reflect the new 14% rate on income up to $58,523 (2026 thresholds). CRA’s payroll deduction tables for 2026 reflect this change.

- When filing your 2025 return (in 2026), note that while rate changed mid-year, the full-year blended rate (14.5%) applies in calculations for whole year credits in many cases. ([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))
- Retain documentation for any claimed non-refundable credits; CRA may verify how they calculated eligible amounts given the rate change.
**Bottom line**: The cut in the lowest federal marginal rate puts more money in many workers’ pockets—but it also shifts the value of credits and deductions. Wise planning means understanding how this ripple affects your tax picture.
