What You Need to Know About the Tax Rate Cut
Canada’s Budget 2025 introduced a middle-class tax cut, lowering the first federal marginal personal income tax rate from 15% to 14%. This change took effect on July 1, 2025, impacting income up to $57,375 for the 2025 taxation year.(budget.canada.ca)
It simultaneously lowered the rate used for most non-refundable tax credits to align with this new bracket.(budget.canada.ca)
How This Change Impacts Your Tax Planning
| Scenario | Before July 1, 2025 | After July 1, 2025 | Full-year-2026 rate* |
|---|---|---|---|
| Tax on first $57,375 | 15% | 14% | 14% |
| Full-year amount for those in lowest bracket | 15% on all taxable income up to bracket threshold | Reduced withholding from July to December at 14% | 14% throughout |
*In 2025, for those in the bracket part of the year, CRA computes annualized tax; full 2026 rate is 14%.(canada.ca)
Actionable Planning Tips
- Adjust your withholding: Employers began using new CRA source-deduction tables starting July 1, 2025, so check your paycheck for lower tax deductions.(canada.ca)
- Non-refundable credits matter: Since credit rates (like the CPP, basic personal amount, age amount) use the lowest tax rate, lowering that rate means slightly smaller offsets in taxable income before credit application—important for those with large one-time deductions.(budget.canada.ca)
- Plan income timing: If you expect extra income (bonuses, freelancing) near the end of the year, see if deferring until 2026 could give a higher net benefit due to the full-year rate.
- Estimate tax bills early: With both 2025 and 2026 using the 14% lowest bracket, make projections now—especially if running extra investments or large deductions.
Practical Example
- Suppose you earn $50,000 in wages and nothing else. Before July 1, 2025, that income was taxed at 15% up to your taxable income threshold. From July onward, income earned in the new period is taxed at 14%. So your tax on the first half of the year still 15%, the second half at 14%.
- If you file jointly (two-income family), each person benefits separately—yielding up to $420 of relief per individual in 2026, $840 for two incomes.(canada.ca)
Bottom Line
The 2025 tax rate cut offers real savings, especially for taxpayers in the lower income brackets. To maximize benefit:
- Monitor pay stubs to confirm correct withholding.
- Time income and deductions with awareness of bracket thresholds.
- Understand effects on credit amounts in relation to your full taxable income.
This isn’t just a rate cut—it changes when and how much you keep, offering opportunities for more strategic year-end planning.
