You'll receive NETFILE error 72182 if there's a difference between the amount of repayment of the Home Buyer Plan (HBP) that you've entered in your tax return, and the amount that the CRA has in your file.
To address this issue, check with the CRA to see if the HBP is registered in your name. You can't use your Registered Retirement Savings Plans (RRSP) contributions or your spousal RRSP contributions to repay a Home Buyer's Plan that's registered in your spouse or common-law partner's name. If you have an HBP registered in your name, check if you're reporting the same numbers for the designated payment, withdrawn amount, and remaining balance.
Visit the Contact the Canada Revenue Agency (CRA) to check the HBP registration.
