Canada Payroll - Net Overpayment

Summary:

We're reaching out to see how other Canadian Oracle Payroll customers are managing prior pay period net pay recoveries (not a full pay period reversal).

When we correct Time Cards or Absences, Oracle generates the Retroactive Adjustment correctly and recalculates CPP and EI as expected. Our challenge is with Federal Income Tax, which is recalculated based on the current pay period's taxable earnings.

Based on NPI guidance for prior pay period adjustments, the recovery amount should reflect the net overpayment from the original pay period. We are currently calculating this amount manually using CRA's PDOC. However, the resulting tax calculations do not align with what Oracle Payroll calculates during the Calculate Payroll process.
