RRSP income includes both payments received from an RRSP and withdrawals from an RRSP.
RRSP income is transferred from boxes 16, 18, 20, 22, 26, 28, and 34 of your T4RSP slips.
If you are a participant in either the Home Buyers’ Plan or Lifelong Learning Plan and did not contribute enough (or any) to your RRSP to repay your HBP/LLP as required, the remainder of your HBP/LLP repayment due is included on line 12900.
