Frequently asked questions

Should I contribute to my RRSP or TFSA?

RRSPs usually win when your tax rate today is higher than you expect in retirement; TFSAs often win at lower incomes. Many people use both.

Can I contribute now and deduct later?

Yes. You can carry forward an undeducted RRSP contribution and claim it in a future year when your income, and tax rate, is higher.

Where do I find my RRSP room?

Your RRSP deduction limit appears on your latest CRA Notice of Assessment and in CRA My Account.
