How to Fix an Employee Underpayment
An employee underpayment is awkward, but the fix does not have to be. Whether a missed overtime hour, a wrong pay rate, or an extra deduction pushed the net pay too low, the correction follows the same path. This guide walks through how to fix an employee underpayment, from spotting the short pay early to topping it up cleanly with the employee informed, with two real examples and a printable checklist so your records stay accurate and your next run starts from the right numbers.
An employee underpayment is one of the most uncomfortable things a small employer faces, because your team did the work and the pay came up short. The good news is that the fix follows the same path whether the cause is a missed overtime hour, a wrong pay rate, or an extra deduction. When you know the steps, a short run turns into a clean correction instead of a second problem.
This guide walks through how to fix an employee underpayment, from spotting the short pay early to topping it up cleanly and keeping your records straight. If you are newer to payroll altogether, it helps to start with our guide on payroll processing basics before you dig into the underpayment steps.
What Is an Employee Underpayment
An employee underpayment is any run that pays an employee less than they earned. It happens when a pay rate, an overtime hour, a bonus, or a deduction is entered wrong, so the gross pay comes out lower than it should and the net pay follows it down. The correction is to confirm the missing amount, pay it to the employee, and update the payroll records so the fix is easy to trace.
Underpayments come from three common causes. The first is a wrong pay rate, where a raise was entered wrong or the new rate ran after the old one should have stopped. The second is a missed item, where an overtime hour, a bonus, or a commission was left out of the run. The third is an extra deduction, where a garnishment or a benefit was taken twice. Each cause points to the same fix, which is confirming the missing amount, paying it, and updating the records. For a fuller look at the errors that lead to underpayments, see our guide on common payroll mistakes.
Spot the Underpayment Early
The best correction is the one you never have to make, which is why catching the underpayment early matters. Run the prepay checks before pay goes out, and review the payroll register for the whole run on one page. Confirm the pay dates, the gross pay for each employee, the deductions, and the net pay, then confirm the total net pay matches the amount scheduled to leave the bank account.
An underpayment caught before payday is fixed by correcting the run, which avoids a top up and keeps the records clean from the start. An underpayment caught after payday is still fixable, but it takes a payment on the next run or a separate payment for the missing wages. The goal is the same every time, which is a run that pays the right amount to the right employee and leaves a record you can trace.
Steps to Fix an Employee Underpayment
When you find an underpayment, work through the steps in order so the correction stays clean and the records stay easy to trace.
- Confirm the underpayment. Identify exactly how much was missing and which employee the run affected before you change anything.
- Stop the run if you can. If pay has not gone out yet, pause the run so you can correct it before the deposit leaves the bank account.
- Correct the source. Fix the pay rate, the missed hour, or the extra deduction that caused the underpayment, using the signed document or the timesheet as the source. For more on how the pieces fit, see our guide on how payroll deductions work.
- Talk to the employee. If pay already went out, tell the employee about the underpayment and confirm the missing amount before you send the top up.
- Pay the missing wages. Add the missing amount to the next run as a separate line, or send a separate payment if the next run is too far off.
- Rerun the totals. Recalculate the gross pay, the deductions, and the net pay for the affected employee, and rerun the totals for the whole run.
- Update the records. Keep the original run, the correction, the top up payment, and a short note about what caused the underpayment so the fix is easy to trace.
Example: A Cafe Pays Missing Overtime
Consider a small cafe with hourly employees paid biweekly. After a run goes out, an employee points out their net pay is lower than usual. The owner checks the run and finds one overtime hour from the last day of the period was never added to the timesheet, so the run paid the straight hours and missed the overtime premium.
The owner confirms the missing hour against the time clock, tells the employee about the underpayment, and adds the missing overtime pay to the next run as a separate line. The owner reruns the totals, confirms the new net pay matches the amount leaving the bank account, and keeps the original run, the correction, and a short note about the missed hour with the payroll records. The example shows how a missed overtime hour turns into a clean top up when you confirm the missing amount and tell the employee first.
Example: A Shop Tops Up a Short Bonus
Take a small retail shop with a mix of hourly and salaried staff paid semimonthly. After a run goes out, the owner notices one employee's gross pay is lower than their hours times their pay rate plus the approved bonus. The owner checks the run and finds a sales bonus was entered at half the approved amount, so the employee received the bonus and a short version of it.
The owner corrects the bonus in the run, tells the employee about the underpayment, and pays the missing bonus amount on the next run as a separate line. The owner reruns the totals and saves the bonus approval and a short note about the error with the payroll records. For more on what to keep on file, see our guide on payroll records employers should keep. The example shows how a short bonus is topped up on the next run with a clean record.
How to Prevent the Next Underpayment
A correction is cleaner when the next run does not repeat the same underpayment. The habits below keep the same gap from showing up run after run.
- Finish the setup before the run starts, including the pay schedule, the employees, the rates, and the bonuses.
- Run the prepay checks every run, including the pay dates, the gross pay, the deductions, and the net pay.
- Review the payroll register for the whole run before pay goes out.
- Enter bonuses and rate changes from signed documents, and confirm overtime hours before the run starts.
- Reconcile the total net pay to the bank account every run, and reconcile the month against the bank statement.

Confirm the missing amount first, then pay it on the next run as a separate line or with a separate payment if the next run is too far off.

Can I fix an underpayment before payday?
Yes, and it is the cleanest time to do it. If you catch the underpayment before pay goes out, correct the run, rerun the totals, and confirm the new net pay before the deposit leaves the bank account. Correcting before payday avoids a top up and keeps the records clean from the start.
Does fixing an underpayment mean I am preparing income tax returns?
