How Does an RRSP Contribution Reduce Your Income Tax?

Here is a simple example to help explain.

Joe: Annual Salary:  $50,000

Income Tax Paid:   – $11,036

After-Tax Income:    $38,964


An allowable RRSP contribution can be deducted From your income.  In other words your income will be lower when calculating how much income tax you owe for the year. If your income is lower then the income tax owing would be lower too.

To make this clear, let’s say Joe Salary makes a contribution of $5000.00 to his RRSP. Since this amount can be deducted from his income, his income would be $45,000.

Annual Salary:       $50,000

RRSP Deduction:  – $5,000

Taxable Income:    $45,000

Income Tax owing on $45,000 is $9,194.


Remember Joe paid, $11,036 for someone earning $50,000.

Therefore if we take what Joe paid $11,036 and subtract what he owes $9,194…

Income Tax Paid:  $11,036

Income tax Owing: – $9,194

Tax Refund of: $1842

Remember an RRSP is an income deferral vehicle. Keep in mind that down the road, monies withdrawn from an RRSP are subject to taxation as earned income.

2017 RRSP deadline is Wednesday March 1st.
