What’s Changed for 2026 in Canada
On July 1, 2025, Canada reduced the lowest federal personal income tax rate from 15% to 14.5% for 2025, then to 14% starting in 2026. (canada.ca) Bill C-4 (“Making Life More Affordable for Canadians Act”) enacted this change. The threshold for this rate is income up to CAD 58,523. (canada.ca)
Impact on Non-Refundable Tax Credits
Non-refundable credits had previously been calculated using the old rate; this means that goods like medical expenses, tuition, volunteer credits, etc., would yield slightly less immediate tax reduction under the new 14% rate. To address that, Canada’s Budget 2025 introduced a Top-Up Tax Credit (Bill C-15) to ensure that taxpayers who would lose more from reduction of credit value than what they save from the rate cut won’t pay more tax in total. This credit applies for 2025-2030. (canada.ca)
Who Feels the Biggest Change?
- Individuals earning ≤ CAD 58,523 will benefit directly from the lower rate.
- Families with two earners, each income below the threshold, may expect savings around double an individual’s, up to roughly CAD 840/year. (canada.ca)
- Those with large claims of non-refundable credits that push them over the threshold may rely on the Top-Up Credit to avoid loss.
- High-income earners may see less take-home change, but could benefit via inflation indexing of other brackets.
Practical Tax Planning Moves
- Review whether tuition, medical, caregiving, or other credits push you over the ~$58,523 threshold; if so, ensure you apply for the Top-Up Credit.
- Estimate tax liability under both old and new schemes to decide whether strategic shifts (accelerating deductions, shifting income) are still valuable.
- Maintain accurate taxable income records, since crossing the threshold triggers changes in rate and credit behavior.
Example Calculation
| Scenario | Taxable Income | First bracket (14%) savings | Non-refundable credits value loss without top-up | Net effect with Top-Up |
|---|---|---|---|---|
| Alice, single, Income CAD 50,000 | Tax under old: 15% on first CAD 50,000 = identical to new since income < threshold | Modest rate drop → saves CAD 500/year | No loss of credit value since credits’ base rate remains at first bracket rate | Net gain CAD ~500 |
| Bob, Income CAD 80,000, large medical & tuition credits | Savings on first CAD 58,523 dropped | Large credits calculated at new 14%, losing some benefit vs old 15% rate | Eligible for Top-Up to restore rate to effectively 15% for the portion of credits over the threshold | Still nets savings; minimal loss thanks to the Top-Up Credit. |
Bottom Line
The middle-class tax cut is real and significant for tens of millions of Canadians. For global practitioners, pay attention to whether clients cross the first bracket boundary, because credit valuations change. Where needed, ensure clients claim the Top-Up Credit so no one slips through a crack.
