Introduction
Canada’s Parliament enacted Bill C-4: Making Life More Affordable for Canadians Act on March 12, 2026, bringing a permanent cut to the first federal personal income tax rate, dropping it from 15% to 14%, effective July 1, 2025.(canada.ca) This benefits nearly 22 million Canadians, especially those in the lowest two tax brackets.(canada.ca)
How It Works in Practice
- For the 2025 tax year: Because the 1% cut began July 1, 2025, the full-year lowest personal tax rate is effectively 14.5%, reflecting two halves of the year—first at 15%, then at 14%.(canada.ca)
- Beginning in 2026 and onward: The rate is 14% full-year for income in the first federal tax bracket. Non-refundable tax credits also scale down accordingly.(canada.ca)
Who Gets the Largest Benefit
- Individuals with taxable income under ~$58,000 in 2026 (first bracket) benefit the most. Two-income families can save up to $840 annually.(canada.ca)
- If you have income primarily from employment and deductions withheld at source, you likely saw increased take-home pay starting July 2025 due to updated withholding tables.(canada.ca)
- Self-employed individuals or those with investment income will see the savings when they file their 2025 returns in spring 2026.(canada.ca)
Actionable Advice
- Review pay stubs since July 2025 to ensure your employer is applying the correct withholding based on the new rate. If not, consider adjusting your TD1 form, or applying for relief through CRA after filing.
- Use updated CRA “What’s New” tools to project taxes and plan spending. The lower first bracket rate means credits are slightly less valuable, so evaluate expenses tied to non-refundable credits.(canada.ca)
- Self-employed individuals should set aside less for federal tax payments for 2025 income; adjust your instalments if needed.
Example Scenario
| Situation | Without Cut | With Cut |
|---|---|---|
| An individual earning $45,000 | First $45,000 taxed at 15% → $6,750 federal tax | First $28,687 taxed at 15%, next $16,313 at 14% → approx. $6,620 federal tax |
| Savings | — | $130 difference |
So, for roughly $45,000 income, the saver sees about $130 less in federal tax liabilities. Savings rise for incomes closer to the top of the first bracket.
Key Takeaway
The 14% rate marks a meaningful shift toward relief for lower- and middle-income Canadians. Review your withholding, file early if possible, and assess your eligibility for credits. This is one of several changes passed under Bill C-4—others include the First-Time Home Buyers' GST/HST Rebate and permanent removal of the federal fuel charge.(canada.ca)
