Key Payroll Deductions in Ontario

Understanding each deduction is crucial for accurate payroll processing. Here's a breakdown of the main deductions:

1. Canada Pension Plan (CPP)

The CPP is a retirement savings plan that employees and employers contribute to. The standard contribution rate is 5.95% of insurable earnings.

2. Employment Insurance (EI)

EI provides temporary income support to workers who become unemployed through no fault of their own. The premium rate is 1.66% of insurable earnings.

3. Income Tax

Note

Insurable earnings are typically the first $62,200 of an employee's earnings, as defined by the Canada Revenue Agency.

Example Calculation

Let's walk through an example to illustrate how to calculate payroll deductions in Ontario.

Scenario

An employee earns $4,000 gross per month. We'll calculate the deductions for this employee.

Step 1: Determine Insurable Earnings

Insurable earnings = $4,000 (since it's below the $62,200 limit)

Step 2: Calculate CPP

CPP = 5.95% of $4,000 = $238

Step 3: Calculate EI

EI = 1.66% of $4,000 = $66.40

Step 4: Calculate Income Tax

Assuming a taxable income of $4,000 and a combined federal/provincial tax rate of 20.5% (for this example):

Income Tax = 20.5% of $4,000 = $820

Step 5: Calculate Total Deductions

Total Deductions = CPP + EI + Income Tax = $238 + $66.40 + $820 = $1,124.40

Deduction Type	Amount
Canada Pension Plan (CPP)	$238.00
Employment Insurance (EI)	$66.40
Income Tax	$820.00
Total Deductions	$1,124.40
