Enter the amount of your RRSP contributions that you designate as repayments of HBP or LLP withdrawals in the Home Buyers' Plan Worksheet or Lifelong Learning Plan Worksheet. You can open the worksheet by clicking Go To Home Buyer's Plan or Go To Lifelong Learning Plan at the bottom of the RRSP entry window.
Enter Home Buyer's Plan (HBP) or Lifelong Learning Plan (LLP) withdrawal or repayment information on a series of screens in the RRSP section of the Interview. Go to the RRSP Profile using the Find window. On the RRSP profile screen, select Repayment or withdrawals for the Home Buyers' Plan (HBP) or Repayment or withdrawals for the Life Long Learning Plan (LLP). Enter the required information in the HBP or LLP interview screens.
Technically, you should have reported these amounts on last year's tax return. You need to file an adjusted return for 2022 to report these amounts in the correct year.
If you prefer not to file an adjusted return, you can include those amounts now with your March 2 to December 31, 2023 contributions. However, retain all your receipts; the CRA may request proof that you did not claim these contributions twice. Note that the CRA might still require you to file an adjusted return to claim the contributions on the correct year's return.
