Our Saskatchewan payroll experts help employers understand and manage payroll tax obligations effectively.
Understanding Payroll Taxes
Payroll taxes in Saskatchewan represent significant employer obligations involving multiple government agencies, complex calculation requirements, and strict compliance deadlines. As an employer, you're responsible for calculating, withholding, and remitting payroll taxes on behalf of employees while also contributing employer portions of certain taxes.
Understanding payroll tax categories is essential for proper compliance. Payroll taxes include mandatory government contributions (CPP, EI), income tax withholding, and provincial taxes. Each has different calculation methods, contribution rates, and remittance schedules.
Key Payroll Tax Categories
Mandatory retirement savings contribution with both employee and employer portions based on employee earnings.
Mandatory employment insurance with employee deduction and employer contribution at different rates.
Withholding based on employee TD1 form and earnings, remitted to Canada Revenue Agency.
Saskatchewan withholding based on employee TD1 form and earnings, remitted to Saskatchewan Finance.

CPP and EI Contributions
Canada Pension Plan and Employment Insurance represent the largest employer payroll taxes. Understanding contribution calculations and limits is essential for accurate payroll processing.
CPP Contribution Rates (2026)
| Component | Employee Rate | Employer Rate | Maximum Contribution |
|---|---|---|---|
| CPP (2026) | 5.95% | 5.95% | $3,867.50 |
| EI (2026) | 1.64% | 2.30% | Employee: $1,049, Employer: $1,469 |
| CPP Exemption | First $3,500 of annual earnings exempt from CPP | ||
EI and CPP Calculation Process
- CPP Calculation: (Gross earnings - $3,500 exemption) × 5.95% (employee) and 5.95% (employer)
- EI Calculation: Gross earnings × 1.64% (employee) and 2.30% (employer)
- Annual Maximums: Contributions capped at annual maximums regardless of earnings level
- Self-Employed Adjustments: Self-employed individuals pay both portions but receive tax credit
- Pensionable Earnings: Include wages, bonuses, overtime, but exclude non-cash benefits
Income Tax Withholding
Income tax withholding is calculated based on employee TD1 forms and gross earnings. Both federal and provincial governments require withholding, and employers remit combined amounts to CRA monthly or bi-weekly.
Income Tax Withholding Requirements
- TD1 Forms: Employees must complete TD1 (federal) and SK428 (provincial) forms declaring deductions
- Withholding Tables: CRA publishes tables determining federal and provincial withholding amounts
- Updated Information: Employees must update forms when personal circumstances change (marriage, dependents)
- Retained by Employer: Withheld income tax is held by employer until remittance deadline
- Remittance Schedule: Amounts remitted monthly (or more frequently for large payrolls) to CRA
Saskatchewan Specific Taxes
Beyond federal requirements, Saskatchewan employers must manage provincial income tax withholding and understand any Saskatchewan-specific payroll considerations or deductions.
Saskatchewan Income Tax Rates (2026)
| Income Range | Provincial Rate | Combined Federal+Prov |
|---|---|---|
| Up to $49,720 | 10.5% | 25.05% |
| $49,720 - $99,440 | 12.5% | 30.45% |
| $99,440 - $173,205 | 14.5% | 32.79% |
| $173,205+ | 16.0% | 35.0% |
Payroll Deductions Summary
Understanding the complete payroll deduction structure helps employers calculate accurate net pay and manage employee expectations regarding deductions.
Mandatory vs. Optional Deductions
CPP, EI, federal and provincial income tax—legally required and cannot be waived by employee agreement.
Pension contributions, benefits (health, dental), union dues, RRSP, parking, meals—require written employee authorization.
Garnishments and child/spousal support require employer deduction and remittance to courts or agencies.
Net Pay Calculation Example
- Gross Pay: $3,000
- CPP Deduction (5.95%): -$168.17

Filing Deadlines and Penalties
Meeting payroll tax filing deadlines is critical. Late payments incur interest and penalties that quickly escalate, and missed filings trigger CRA enforcement action.
Key Payroll Tax Deadlines

- T4 Slips: Due to employees and CRA by end of February following calendar year
- T4 Summary: Filed with CRA by end of February
- Quarterly Adjustments: Some payments require quarterly reconciliation
- Year-End Reporting: RRSP deductions reported by March 1
Penalties for Non-Compliance
Record Keeping Requirements
Proper record keeping protects your business from CRA audits and ensures accurate reporting. Maintain detailed payroll records for minimum six years from year-end.
Essential Payroll Records
- Employee names, addresses, and Social Insurance Numbers
- Hours worked and rates of pay for all employees
- Gross pay, all deductions, and net pay for each pay period
- Employee TD1 forms and benefit election forms
- Payroll tax remittance receipts and proof of filing
- Year-end reconciliation showing total deductions vs. remittances
- T4 copies provided to employees and filed with CRA
Frequently Asked Questions
Employee payroll taxes are deducted from employee wages (CPP 5.95%, EI 1.64%, income tax). Employer payroll taxes are costs paid by the employer in addition to employee wages (CPP 5.95%, EI 2.30%). Employers are responsible for both employee withholding and employer contributions. This means total payroll costs significantly exceed gross wages.
Most Saskatchewan employers remit payroll taxes monthly by the 15th of the following month. Larger employers may be required to remit bi-weekly or even more frequently. Payment frequency depends on total annual payroll tax liability. Employers are notified by CRA of their required remittance schedule.
Late remittance incurs a 10% penalty for the first month late (increasing for extended delays), plus 20% interest on the unpaid amount. Additionally, CRA may freeze business bank accounts and take legal action to recover amounts owed. Directors can be held personally liable for unpaid payroll taxes in some circumstances.
Yes, part-time employees are subject to the same payroll tax requirements as full-time employees. CPP applies to earnings above $3,500 annually, and EI applies regardless of hours. Income tax withholding applies based on earnings. There are no exemptions based on employment status—all employees require payroll processing.
T4 slips must be provided to employees and filed with CRA by February 28 (or March 15 if filing electronically) following the calendar year. For example, 2025 T4s are due by February 28, 2026. Late filing incurs significant penalties ($25-$100+ per slip depending on days late).
