One of the most reliable ways to check your current year deduction limit is to log in or register for an online account with the Canadian Revenue Agency. Alternatively, you can also check your latest notice of assessment.

If you're having trouble finding your deduction limit, here's a step by step instructions (with screenshots!) to guide you:

1. Go to the CRA My Account Login.
2. Log in with your preferred method. If you've set up your bank as a sign-in partner, this is the simplest way to access your CRA account.
3. Under the tabbed header, navigate to RRSP and TFSA.
   
   
   
4. Click RRSP.
   
   
   
5. Highlighted below is your RRSP deduction limit. If you're setting up your RRSP contribution tracker, you'll need to stay on this page for the next step.
