What is Retroactive Pay?
Making up wages an employee was owed but not paid in a past period - a delayed raise or a payroll error.
Retroactive Pay: definition
Retro pay corrects the gap between what an employee was paid and what they should have been paid in a prior period. It commonly arises when a raise is approved effective an earlier date but not processed in time, when overtime or a shift differential was missed, or when an error underpaid someone. It is taxable wages like any other pay, and it differs from back pay awarded for wrongful non-payment, though the terms overlap.
- Makes up underpaid wages from one or more prior periods
- Common causes: late raises, missed overtime, payroll errors
- Taxable as regular or supplemental wages
- Calculated as the difference between what was paid and what was owed
How Fintra handles it
Fintra payroll can calculate retro pay by comparing what was paid to what should have been paid across the affected periods, add it to the current run with correct tax treatment, and post the adjustment to the ledger. Because history sits on one model, the correction is auditable - showing the original amount, the corrected amount, and the difference paid.
- Retro amount computed from prior-period underpayment
- Added to the current run with correct tax treatment
- Adjustment posted to the ledger with an audit trail

Frequently asked questions
What is the difference between retro pay and back pay?
Retro pay corrects an underpayment - the employee was paid, just not enough, often due to a late raise or error. Back pay refers to wages owed but not paid at all, frequently in the context of a legal claim or settlement. The terms are related and sometimes used interchangeably.
How is retroactive pay calculated?
By finding the difference between what the employee was actually paid and what they should have been paid for the affected periods, then paying that difference. For a late raise, it is the rate difference times the hours worked at the old rate.
Is retro pay taxed differently?
Retro pay is taxable wages. If paid as part of a regular paycheck it is taxed with those wages; if paid separately it may be treated as supplemental wages with its own withholding method. Either way, all normal payroll taxes apply.
What causes the need for retro pay?
Common causes include a pay raise or promotion applied effective a date before it was processed, missed overtime or shift differentials, incorrect hours, or a payroll system error. Prompt correction keeps employees whole and avoids wage-compliance issues.
