c) Sally made a Registered Retirement Saving Plan (RRSP) contribution in January 2020 to claim as a deduction on her 2019 personal income tax return. She knew how much to contribute based on her Canada Revenue Agency (CRA) Notice of Assessment, which shows her the RRSP deduction limit (i.e. how much she can contribute). Sally does not have any RRSP carry-forward amount as she always maximizes her annual contribution. Rather than rely on her Notice of Assessment from the government, she would like to know how to calculate the contribution amount and has asked you for your help. Show Sally how you would calculate her 2019 RRSP contribution. Also, show her how you calculate her expected refund from making this RRSP contribution based on her marginal tax rate. She is very excited to know this information as she just filed her tax returns before the revised deadline and is expecting a refund shortly. (Ignore Non-Refundable Tax Credits)
