Key Changes to Federal Tax Rates and Withholding in 2026
Starting July 1, 2025, the lowest federal personal income tax rate will drop from 15% to 14%, with 14.5% applying for the first half of 2025. For the 2026 tax year, the full year rate of 14% applies. (canada.ca)
Alongside this, the non-refundable tax credit rate—used to calculate various personal credits—will adjust to match the lowest rate, which means a drop from 15% to 14.5% in 2025, 14% starting 2026. (budget.canada.ca)
Payroll Withholding: What Needs Updating
Employers and payroll professionals should be aware of impactful adjustments:
- Source deduction tables: these have been updated for July–December 2025 so withholding reflects the lowered rate. (canada.ca)
- Payroll deductions guides (such as CRA’s Guide T4032 and Supplementary Tables) will reflect these new thresholds and constants for 2026. Use the latest digital versions. (canada.ca)
- Provinces and territories may also have updated Basic Personal Amounts (BPA) or other provincial brackets—employers must sync both federal and local changes. (canada.ca)
Example: How It Changes Take-Home Pay
Suppose Fahim earns $45,000 annually and lives in Ontario.
- Under the old lowest federal rate of 15%, his deductions on taxable income in the first bracket were higher.
- With the rate reduced to 14%, he begins saving immediately—either via increased take-home pay (after July 1, 2025 withholding changes) or via a larger credit when he files his 2025 return.
Keep in mind: although full-year 2025 tax calculation will include two rates (14% for second half), payroll deductions may lag behind—check with CRA source deduction tables.
Action Steps for Employers
- Install updated withholding rates for your payroll system as of July 2025 to avoid under- or over-withholding.
- Communicate with employees about expected changes in net pay.
- Review exempt amounts or provincial BPAs if affected in your province.
- Stay alert to CRA aggiornamenti—Canada.ca provides payroll deduction tables and charts that must be used from January 2026 onwards. (canada.ca)
Pitfalls to Watch Out For
- Using outdated tables or guides can lead to tax compliance issues—employees under-withheld may owe when filing.
- Failing to adjust non-refundable credit rate may result in mis-calculated credits.
- Overlooking provincial changes—every jurisdiction has its own rate structure.
When in doubt, consult with a payroll expert or tax professional to avoid surprises during the 2026 tax season. Getting things right now can save headaches for both your business and your employees.
