Payroll audit trail
A payroll audit trail is the stored record of who took each consequential payroll action, when, and what changed.
Every entry preserves the actor, the timestamp, the requested action, the prior state, the resulting state, and any exception. A completed run or a rate change can then be reconstructed months later without relying on anyone’s memory. Reports show results; the audit trail shows decisions. Separation of duties in payroll keeps one person from both creating a payroll change and approving it. The trail records who did what at each stage.
What belongs in a payroll audit trail?
A payroll register proves the figures of a run but not how they came to be. The audit trail supplies the rest: the rate that changed, the user who changed it, and the approval that released the run. Neither proves remittance on its own: proof of deposit comes from the payment confirmation and the agency account. Positive pay is a bank check-fraud service, separate from the trail: you send the bank each issued check’s number and amount, and the bank flags any presented check that does not match.
| ACTION | WHAT THE ENTRY RECORDS |
|---|---|
| Any payroll action | Employer, payroll or record identifier, user, timestamp, action requested, and prior and resulting values |
| Compensation change | Employee, old and new amount, effective date, source of the request, actor, and time of the edit |
| Access or configuration change | The same shape: who gained a permission matters as much as what a rate became |
| Manual adjustment | A label and, where the amount is consequential, a reason and a second review |
| Acknowledged warning | Who reviewed and accepted it, which turns a dismissed alert into evidence instead of a gap |
