## What To Do Before Filing
### Payroll withholdings
Employers should have begun using the updated rate for pay periods from **July 1, 2025**, onward. That means more money in your paycheck if your employer updates properly.

### Tax credits and deductions
Since non-refundable tax credits get calculated using the first marginal rate itself, you’ll see slightly enhanced value from any credit you’re eligible for. Review your claimed credits to make sure you’re maximizing them.

### Filing your return in 2026
When you file your 2025 return (spring 2026), the blended rate for that first bracket will be **14.5%**, not 15% or 14%. Double-check pay slips and any forms to ensure accurate withholding.

## Examples
| Scenario | Income | Savings Estimate |
|---|---|---|
| Single person earning $30,000 in 2025 | ~$30,000 | Approximately **$113** saved vs. the old rate (half-year effect) |
| Two-income household with both earners in first bracket | Combined $55,000 | Savings could approach **$400–$450 total**, depending on credits |
## Bottom Line
The drop from **15% to 14%** at the federal level for the first income tax bracket is a **key affordability measure**, benefitting millions of Canadians. Make sure your withholding is up to date, and evaluate your tax or credit claims accordingly when filing your 2025 return.
