Navigating Source Deductions

As a Canadian employer, you act as a trustee for the government. Mastering CRA Payroll Deductions is essential for avoiding the heavy penalties associated with late or incorrect remittances.

Understanding the Big Three

When calculating CRA Payroll Deductions, you must focus on Income Tax, Canada Pension Plan (CPP), and Employment Insurance (EI). Each has its own specific rates and annual ceilings that change every January 1st.

Employer Contributions

Remember, CRA Payroll Deductions aren’t just about the employee’s share. Employers must match CPP contributions and pay 1.4 times the employee’s EI premium. Budgeting for these additional costs is vital for your financial health.

Filing Remittances on Time

The frequency of your remittances (monthly, quarterly, or accelerated) depends on your average monthly withholding. Missing a deadline for CRA Payroll Deductions can lead to penalties ranging from 3% to 10% of the amount owed.

Taxable Benefits and Allowances

Conclusion
