Each year, the amount you can contribute to your RRSP depends on how much you’ve earned. You can contribute 18% of your total income earned in the previous year, up to a maximum limit set by the government (in 2022, this amount is $29,210), plus any unused contribution amounts of earlier years.
To find out your RRSP contribution limit for this tax year, check your Notice of Assessment from the previous tax year or log in to My Account on the CRA website.
