With Bill C-4 bringing in a 1 percentage-point cut to the lowest personal tax rate starting July 1, 2025, individuals in the two lowest federal brackets will see significant relief—this article explains who benefits, how to claim it, and strategies to maximize your tax planning under the new rates.

## Overview of the Rate Change
Bill C-4, the *Making Life More Affordable for Canadians Act*, received Royal Assent March 12, 2026, and includes **a reduction of the first federal marginal tax rate from 15% to 14% starting July 1, 2025**. Nearly 22 million Canadians will benefit, especially those whose income places them in the lowest two federal brackets (roughly under **$117,045 taxable income** in 2026).

This change affects how much tax you owe for tax year 2025, given the rate change occurs mid‐year. The first bracket (up to approximately $58,523 in 2025) will be taxed at 15% for the first half of the year and at 14% for the second half. The resulting **average rate across the year will be about 14.5%** for most individuals in that bracket.

## Who Gets the Most Relief
| Profile | How they benefit |
|--------|------------------|
| Lowest bracket ($0 to ~$58,523) | The full rate reduction, with up to **$420 per person** annual saving if taxable income covers periods before and after July 1. Married/common-law couples may see **double**, i.e., **$840** total.

| Bracket from ~$58,523 to ~$117,045 | Some benefit on the portion of income in the lower bracket. If you're substantially above, the benefit is proportional to the amount that falls below threshold post rate cut. |
| Self-employed / uneven income | If income distributed unevenly across the year, consider timing income/expenses to fall more into the lower rate period when possible. |
## Tax Planning Strategies
- **Deferring income**: If you anticipate your income will rise during the second half of 2025, you may shift deductible expenses or defer income to after July 1, to benefit from the lower rate.
- **Prepay deductions** (such as RRSP contributions or eligible expenses) before July 1, if you expect you're in the lowest brackets during both halves.
- **Review withholding and payroll deductions**, particularly if you're an employee—ensure your employer has updated payroll calculations and remittances to align with new bracket thresholds.
- **Leverage refundable credits**, since credit calculations depending on taxable income could yield greater relative benefit when your marginal rate drops.
## Compliance Considerations
- Confirm with your tax software provider or financial planner that they’ve incorporated the 14% rate from July 1; errors here could result in overpayment or underpayment.
- For part‐year residents or those who moved between provinces, mix of provincial rates adds complexity.
- Keep careful documentation for any shifted income or expenses near mid-year; CRA may inquire where timing impacts your bracket allocation.
## Example
Sarah earns $50,000 in taxable employment income, paid evenly over 2025. Prior to Bill C-4, she’d pay 15% on all income in the lowest bracket. With 14% rate from July 1 onward, she pays 15% on the first half ($25,000) and 14% on the second half. She saves about **$125** in federal tax compared to the old rate applied all year. For higher incomes, the savings may be larger depending on how much falls into the first bracket.
## Action Items Before Your 2025 Return
- Gather your total income data and allocate what was earned before vs after July 1.
- Adjust withholdings or instalments if you anticipate owing tax, to avoid interest.
- Use this opportunity to review your bracket positioning for next year (2026)—if you expect similar incomes, planning can carry over into future tax years.
**Bottom line**: even a 1% change in a rate bracket can meaningfully impact your after-tax income. If you fall into lower federal brackets, paying attention to timing and deductions in 2025 can help you lock in savings now.
