## What changed and why it matters
In **Bill C-4**, which received Royal Assent on March 12, 2026, the federal government officially lowered the lowest personal income tax rate from **15 % to 14.5 % for the 2025 tax year**, and to **14 % for 2026 and onwards**. ([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 affects Canada's approximately **22 million people** in the lowest two tax brackets, especially as many non-refundable credits are calculated using that rate.

## How non-refundable credits are impacted
Many credits (e.g. the Canada Employment Credit, Volunteer Firefighters Amount, Disability Credit, Medical Expense Credit, etc.) use what's called the **"appropriate percentage"**—which until recently was based on the 15 % lowest rate. With the cut to 14 %:
- That percentage drops accordingly, so credits are worth **slightly less in absolute dollars** if they’re applied against your taxes at the lowest rate.

- However, taxpayers in those brackets **still save money overall** because taxable income is taxed at a lower percentage. The net effect is **positive** for most.
## Who benefits most
- Individuals with modest incomes taxed mostly at the lowest rate—**say up to ~$60,000 CAD**—especially those claiming multiple credits tied to low-income segments.
- Two-income families with both partners in lower/first two brackets—savings compound. Bill C-4 estimates savings of up to **$420/person**, and **$840 for couples** in 2026.

## What to watch out for
- Credits based on **income thresholds** might phase out sooner for some because their interaction with taxable income changes—but the general income brackets have not yet been adjusted for many credits. Stay current with CRA tables.
- If taxable income spans more than one bracket, it’s the **first portion** that enjoys the lower rate. Higher portions are taxed at higher marginal rates. Be sure your income-splitting, RRSP/TFSA contributions, or deductions align with this structure.
## Example calculations
| Scenario | 2025 (15 %) | 2026 (14 %) | Annual savings* |
|---|---|---|---|
| Single individual earning taxable income of $40,000, claiming credits worth $3,000 | Taxes on lowest portion ($40,000) = $6,000 | Taxes ≈ $5,600 | **$400** |
| Two-income family (each earning $50,000), joint credits $6,000 | Each taxed at 15 % → combined tax on bracket ≈ higher | With 14 % rate → less | **Up to $840 total** |
> *Estimates based on taxable income portions within lowest bracket; actual saving depends on deductions, provincial rates, credits claimed.
## Actionable steps for taxpayers and advisors
- **Review your non-refundable credits**: see what you're claiming and recast calculations under the 14 % rate to understand actual benefit.
- **Maximize income shifting and splitting** where possible**, so more income falls into the lower brackets (common-law or spousal loans, trusts, etc.).
- **Optimize deductions and RRSP contributions** so taxable income stays lower, especially if that keeps your marginal rate at 14 %.
- **Tax planning software or accountants**: ensure updated rates (2026+) are used to compute your returns and advice.
## Long-term lens
The rate reduction is part of a broader affordability agenda. It’s permanent, not temporary. As of June 2026, the CRA’s system and tax publications are reflecting this change. For 2026 tax returns and beyond, this is now standard.
