The Canada Revenue Agency takes into consideration the Pension Adjustment Reversal (PAR) amount reported in box 2 of the T10 slip to determine the RRSP deduction limit for the year indicated in box 1. This will result in an increase of the RRSP deduction limit for that year.
ProFile T1 does not include slip T10. However, this amount can be entered in ProFile T1 on the RRSP form, under the section RRSP deduction limit, at line year of tax return pension adjustment reversal from T10 slip.
