What’s Changed
- The Making Life More Affordable for Canadians Act (Bill C-4) received Royal Assent on March 12, 2026. Among its reforms is a reduction in the first federal personal income tax rate—from 15% down to 14%, effective July 1, 2025.(canada.ca)
- Concurrently, non-refundable tax credits that use the lowest tax rate for their calculation are impacted—those credits yield less when the applied rate is cut. To avoid potential adverse effects, the government is introducing a new Top-Up Tax Credit to protect those claiming large non-refundable credits exceeding the first bracket threshold.(budget.canada.ca)
Who is Affected
This affects taxpayers who:
- Qualify for substantial non-refundable credits (e.g., tuition, medical expenses, disability or age amounts), especially if some credits are carried forward or combined across dependents.
- Have income near or above the first-bracket threshold ($57,375 for 2025) and thus have credits computed partly beyond the lowest rate. These individuals may find their credit value falls unless they receive the Top-Up Credit.(budget.canada.ca)
What is the Top-Up Tax Credit
- A temporary credit functioning for 2025 through 2030, designed to bridge the gap between the old 15% rate and the new 14% rate for affected non-refundable credits over threshold amounts.(budget.canada.ca)
- Applies when non-refundable credits exceed the first personal tax bracket threshold; ensures taxpayers in those upper ranges aren’t worse off due to the rate change.(budget.canada.ca)
Actionable Advice
- Estimate your expected non-refundable credits for 2025: Include tuition, medical, disability, pension income, and any carried-forward credits. If they significantly exceed the first bracket limit, plan accordingly.
- Consider the timing of large expenses or donations: Expenses that generate non-refundable credits may be more advantageous in years with lower income (under the threshold) or when you can optimize the benefit considering the Top-Up Credit.
- For students and dependents: If carrying forward tuition or other credits, ensure you understand how the expiry or usage aligns with threshold and rate changes.
- Use tax software or a preparer familiar with the new credit to ensure you get the Top-Up Credit if eligible.
Example Scenario
Imagine Jane has $70,000 in taxable income in 2025 and claims $15,000 in tuition and other non-refundable credits. Under the old rate (15%), her credits reduce tax by about $2,250. Under the new 14% rate, that benefit falls to $2,100, a $150 loss. The Top-Up Credit is intended to compensate for that kind of shortfall for amounts over the threshold.
Summary & Tips
- The tax rate cut brings relief for nearly 22 million Canadians, including many middle-class taxpayers.(canada.ca)
- But for those with high non-refundable credits, the rate change alters the value of these credits—prompting the need for the Top-Up Credit. Consider planning ahead and timing large expenses or maximizing credits wisely.
- As this Top-Up Credit is only temporary (2025-2030), long-term planning should aim to spread credit-generating activities or structure income so as to minimize any loss.
