## What’s Changed
Under **Bill C-4, the Making Life More Affordable for Canadians Act**, the **lowest federal marginal personal income tax rate** has been permanently lowered:
- From **15% to 14.5%** for the 2025 taxation year ([canada.ca](https://www.canada.ca/en/department-finance/services/publications/report-impact-reducing-lowest-marginal-personal-income-tax-rate-non-refundable-tax-credits.html?utm_source=openai))
- **14%** for the **2026 taxation year and beyond ([canada.ca](https://www.canada.ca/en/department-finance/services/publications/report-impact-reducing-lowest-marginal-personal-income-tax-rate-non-refundable-tax-credits.html?utm_source=openai))
This change affects the first bracket of taxable income in 2026, which goes up to **$58,523** at the new 14% rate ([canada.ca](https://www.canada.ca/en/revenue-agency/services/tax/individuals/tax-rates-brackets/current-year.html?utm_source=openai)).
## What This Means for You
- Non-refundable tax credits (e.g. basic personal amount, medical expenses, donations) will now carry a lower value, since these credits are multiplied by the lowest tax rate. For example, a credit worth $1,000 now reduces taxes by **$140** instead of $150 ([canada.ca](https://www.canada.ca/en/department-finance/services/publications/report-impact-reducing-lowest-marginal-personal-income-tax-rate-non-refundable-tax-credits.html?utm_source=openai)).
- For individuals in higher tax brackets, deductions and credits beyond the first bracket yield less benefit in relative percentage terms.
## Strategic Moves to Maximize Benefit
- **Accelerate income into 2025-2026** if you're currently near the bracket threshold. Take steps like delaying deductions or recognizing income earlier if it helps shift part of your taxable income into lower brackets.
- **Pre-pay expenses or charitable contributions** before year-end to maximize deductions anchored in the lower rate period.
- **Optimize splitting income or leveraging spousal transfers**, especially where one spouse has significantly lower income; shifting income-producing assets or investments can reduce family overall tax burden due to progressive bracket benefits.
- **Revisit non-refundable credits**: Medical and disability expenses, tuition, caregiver amounts — since their effect is now 14%, larger credits may be needed to reduce tax dollars as before.
## Examples
| Scenario | Old Situation (2025 @ 15%) | New Situation (2026 @ 14%) |
|----------|-----------------------------|-----------------------------|
| Single person with $1,000 charitable gift | Credit = $150 reduction | Credit = $140 — net savings $10 lower |
| Married couple splitting income | Income shifts that move portion into first bracket benefit from 14% vs old higher rate |
| Self-employment income | Structuring expense timing or splitting income helps maximize lower-rate portion |
## Key Actions Before Filing 2026 Return
- Confirm your **province’s tax brackets and rates** — federal changes interact with provincial rates ([canada.ca](https://www.canada.ca/en/revenue-agency/services/tax/individuals/tax-rates-brackets/current-year.html?utm_source=openai)).
- Ensure your **tax software or payroll withholding** reflects the 14% lowest rate starting in January 2026 ([canada.ca](https://www.canada.ca/content/dam/cra-arc/migration/cra-arc/tx/bsnss/tpcs/pyrll/t4032/2026/t4032-mb-1-26e.pdf?utm_source=openai)).
- Review your eligibility and benefits you receive — including the **Canada Groceries and Essentials Benefit (CGEB)** replacing the GST/HST credit — to make sure you’re capturing all support measures.
