FAQ: The Legalities of Salary Overpayments

Can Employers Recover Overpaid Salary?

Yes. Under UK law, employers have the right to reclaim wages they have paid in error. This applies whether the overpayment happened once or has accumulated over several months.

The legal basis for recovery rests on a simple principle: money paid by mistake is not money owed to the recipient. An employer who pays more than the agreed salary can treat the excess as a debt and seek repayment. In practice, however, the mechanics of recovery involve more nuance than this suggests.

The Employment Rights Act 1996 includes provisions that allow deductions from wages to recover overpayments. Section 14 of the Act exempts overpayment recovery from the usual restrictions on wage deductions. That said, standard practice is for employers to obtain agreement on repayment terms before making deductions, both to avoid disputes and to act reasonably where the overpayment resulted from their own administrative error.

Most employers will try to reach an agreement with the employee rather than deducting the full amount in one go. While employers are not strictly required by law to notify staff before making deductions to recover overpayments, doing so is standard practice and reduces the risk of grievances or tribunal claims.

Why Do Overpayments Happen?

Several factors can lead to an employee receiving more than their correct salary:

  • Incorrect salary details entered by the payroll department
  • A manager providing the wrong figures for a new starter
  • System errors following a pay rise or job change
  • Holiday pay or bonuses calculated incorrectly
  • Continued payments after an employee has left or reduced their hours
  • Late processing of unpaid leave or deductions

New employees are particularly at risk. During onboarding, salary information passes through several hands, and a single incorrect digit can result in overpayment from the very first pay packet.

Small overpayments may go unnoticed for months. Many people do not scrutinise their payslips closely, particularly if the discrepancy is only a few pounds. The problem tends to reveal itself only when finance departments conduct audits or when an employee queries something unrelated.

Many employers have internal policies designed to catch overpayments early. It is worth asking your HR department what checks are in place and whether you can access records of what you should have been paid each month.

What Should You Do If You Spot an Overpayment?

If you notice you have been paid more than expected, contact your payroll department or line manager promptly. It is important to verify whether the extra money is actually yours to keep, as assumptions can lead to problems later.

Acting quickly serves your own interests. Overpayments that go unreported will continue to build up, leaving you facing a larger sum to repay later. The sooner the error is corrected, the simpler the resolution will be.

When you raise the issue, ask for confirmation in writing. Request details of exactly how much you have been overpaid and how the employer intends to recover it. This protects both sides and creates a clear record.

If you are not sure whether an overpayment has occurred, check your employment contract for your agreed salary and compare this against your payslips. You can also ask HR or payroll to confirm what you should have received.

Be aware that tax and National Insurance may complicate matters. If you repay a gross overpayment but originally received a net amount after deductions, your employer should adjust their records so that HMRC reflects the correct position. Ask your payroll team to confirm how this will be handled.

How Will the Overpayment Be Recovered?

Employers can lawfully deduct overpaid amounts from future wages under the Employment Rights Act 1996. However, best practice is for employers to discuss the situation with you first and agree on a repayment arrangement that does not cause financial hardship.

For larger sums, employers may offer to spread recovery over several months. If the full amount in one deduction would cause you difficulty, it is worth explaining your circumstances and proposing a schedule you can manage. Many employers will be flexible, particularly if the error was theirs, though there is no legal obligation on them to accept your proposal.

If an overpayment is discovered after you have left a job, your former employer may contact you to request repayment directly. They can pursue this as a civil debt if you refuse to pay.

Should you be unable to reach an agreement with your employer about repayment terms, you have options. Raising a formal grievance through your workplace procedure is one step. Acas provides free guidance on workplace disputes and can help clarify your rights. Citizens Advice can also assist with questions about debt and deductions from wages. If the matter escalates, you may be able to bring a claim to an employment tribunal if you believe an unlawful deduction has been made.

Note that some sectors may have additional rules. Public sector employees or those covered by collective bargaining agreements may find that their union has negotiated specific procedures for handling overpayments.

For detailed information on wage deduction rules, refer to the official guidance on GOV.UK. Keeping your own records of payslips and employment correspondence will make it easier to resolve any disagreements that arise.
