You may have to repay OAS benefits (see line 23500) if the result of the following calculation is more than $86,912:

The amount recovered from your gross OAS pension because of an overpayment that you received for a previous period is shown in box 20 of your T4A(OAS) slip. You can claim a deduction on line 23200 for the amounts repaid.
