What’s Changed:
- As of July 1, 2026, updated T4032 payroll deduction tables are in effect across all provinces and territories. These include changes to Federal, Provincial/Territorial income tax, CPP, and EI deductions. (canada.ca)
- In British Columbia, the lowest provincial tax rate increases from 5.06% to 5.60%, with a prorated rate of 6.14% applying for the remainder of the year. Also, tax reduction thresholds have been adjusted, affecting those with incomes up to approx $25,570 and partial reductions up to $44,952. (canada.ca)
- The Payroll Deductions Formulas T4127 (123rd Edition) have also been updated, reflecting changes in BC, Newfoundland and Labrador, and Prince Edward Island, and including adjustments to thresholds, constants, and claim codes effective July 1, 2026. (canada.ca)
Who’s Affected:
- Employees in BC especially, whose withholding will increase via higher base tax rates. Your paycheques may show slightly lower take-home pay, particularly in the second half of 2026.
- Employers/payroll providers: You’ll need to update payroll software to use new tables; failure to withhold correctly could result in shortfalls for employees or extra costs for businesses.
- Revenue agency compliance teams monitoring correct application of deductions.
Practical Steps to Stay Compliant:
- Review your payroll software/configuration immediately to ensure it uses the July 1 tables. Confirm that federal and provincial tax tables and constants are properly updated.
- Communicate changes to employees, especially in BC, so they understand why their take-home pay might change.
- Update TD1 personal tax credit forms, especially if employees’ situation changed (e.g. moving provinces) to claim the correct personal amounts. Claim codes are updated in T4127. (canada.ca)
- Pay attention to prorated rates, particularly for the first part vs second half of 2026 in BC’s lowest bracket. Employers need to apply the correct rate depending on pay period. (canada.ca)
- Monitor CRA guidance for further provincial changes — some provinces (NL, PEI) also have tweaks in T4127 updates. (canada.ca)
Example Scenario:
- Sarah works in Metro Vancouver earning $50,000 annually.
- Before July 2026, her BC provincial rate on her first $50,363 was 5.06%. After July 1, withholding jumps to 6.14% prorated.
- This leads to more tax being taken per pay period in the second half of 2026. Even though annual rates for BC’s higher brackets are untouched, this affects cash flow.
Key Takeaways:
- Payroll changes like these don’t usually mean higher income tax liability overall—they shift how and when tax is withheld.
- The lowest potential withholdings are happening now; adjustments and refunds still occur at tax-time based on income and credits.
- Keeping payroll systems up to date, communicating clearly, and encouraging employees to review their tax credit forms can reduce surprises.
Stay informed: Always refer to the CRA’s latest publications such as T4032 and T4127, and provincial notices to ensure your payroll processes reflect legislation as enacted.
