## What changed and why it matters
In Budget 2025, the Canadian federal government lowered the **first marginal personal income tax rate** from **15 % to 14 % effective July 1, 2025**, with full effect in 2026. This means taxable income in the lowest bracket is taxed at 14 % throughout most of 2026. Because non-refundable tax credits are typically valued at this rate, **credits like the basic personal amount give slightly less tax savings than they would at 15 %**.

## Planning strategies you can use now
- Review timing of income: If you control when certain income (like capital gains, dividends) is realized, shifting income to earlier or later tax years may change whether it’s taxed at the lower rate or not. Income earned before July 1, 2025 still sees 15 %; after, the lower 14 %.
- Optimize non-refundable credits: Credits such as tuition, basic personal, age, disability, etc., will now yield **14 cents in tax savings for every eligible dollar**, down from 15 cents. If you expect to have large non-refundable credits, plan expenses or income so those credits are used in years where your marginal rate is higher.
- Spouse/common-law strategy: If spouse has little income, shifting deductions to use their first bracket can yield savings. With both spouses benefiting from 14 %, ensure eligible deductions are allocated optimally.
- RRSP contributions: The tax benefit from RRSP contributions depends on your marginal rate. If you expect to be in a higher bracket in future years, delaying large deductions until then may increase value—but balancing this with opportunity cost is key.
## Examples
- **Example 1**: Alice earns taxable income that falls in the first bracket during 2025. If she incurs **$2,000 in tuition**, at 15 % she saves **$300**, but in 2026 she saves **$280**. If she expects to move into a higher bracket in 2026, she might defer tuition payments to benefit more.
- **Example 2**: Bob is married to Casey. Bob earns much but Casey earns very little. Credits that Casey can’t use due to low income could be transferred; given that the credit is now worth 14 %, maximizing Casey’s first bracket (and thus her credit value) should be optimized.
## Pitfalls and what to watch for
- Province/territory taxes: Rates vary, and combined federal-provincial rates may shift which bracket is “lowest”. Always model combined liability.
- Incremental vs bulk deductions: Large deductions in low-rate years often yield smaller “per dollar” savings. If your taxable income crosses into higher brackets, those extra dollars may be taxed more.
- Inflation adjustments: Brackets are inflation-indexed. Watching when your income reaches a bracket threshold is still vital.
## Actionable steps for 2026
1. Calculate your estimated taxable income and identify if much falls into the **first federal bracket** under 14 %.
2. Gather potential non-refundable credit-eligible expenses (tuition, medical, etc.), and see whether shifting them across spouses or across years yields a better value.
3. Use tax software or consultants to model your liability with different scenarios, especially if you expect income shifts.
4. Review your RRSP limit, carryforwards, and contributions to see where maximum deduction value can be realized.
**Bottom line:** The drop from 15 % to 14 % on the first federal rate is small in percentage but significant in strategy. By understanding how it affects credit value, your deductions, and income timing, you can squeeze extra savings in 2026.
