Overpaid wages? What your employer can take back
Payroll errors are common in care, NHS bank and agency work. Yes, your employer usually wants the money back. No, they cannot just take what they like.
Double pay for one week. The wrong hourly rate for months. An extra £150 sitting in your bank that felt like luck. Then payroll emails: we overpaid you, we are taking it back. Here is what they can do, what they cannot do, and what to write back today.
- No form
- consent not needed for genuine overpayments
- Net only
- repay take-home pay, not gross with tax
- £12.71
- National Living Wage rate from 1 April 2026
- 6 mths
- tribunal deadline for deduction disputes in Britain
What to do today
Do not ignore the letter. Do not agree to anything on the phone. Payroll errors favour whoever has the paperwork, so get yours in order before money moves.
- Ask for it in writing. Request the gross and net overpayment, which pay periods it covers, how it happened, and how they calculated it. Ask for corrected payslips.
- Check it yourself. Pull your contract rate or booking confirmation, timesheets or rotas, bank statements and payslips. Many “overpayments” turn out to be correct pay, owed arrears or unpaid hours.
- Do not spend a suspicious payment. If a sum lands that you did not earn, leave it alone and query it. Spending it rarely helps you resist repayment later.
- Propose a plan in writing. Offer staged repayment over the same period the error built up. Keep copies of everything and join a union before you reply if you can.
Can they take it without my permission?
Usually, yes. That shocks people, but the law is blunt on this point.
Section 13 of the Employment Rights Act 1996 bans unlawful deductions from wages. Section 14(1)(a) then carves out “an overpayment of wages … made (for any reason)”. Where the purpose of the deduction is to reimburse that overpayment, section 13 simply does not apply. No written consent needed. No clause needed in your contract.
The same exception lets an employer demand a direct payment back from you under section 16. It covers employees and limb (b) workers alike, so zero-hours, casual, term-time and bank staff get the same rough treatment. Agency and umbrella workers count too: whoever pays you is the “employer” for these purposes.
There is one hard limit the tribunal enforces: there must actually have been an overpayment. If you can show nothing extra was paid, the section 14 shelter collapses and the deduction becomes unlawful. Keep that distinction in mind for everything that follows.
| Situation | Lawful? | Why |
|---|---|---|
| Genuine extra pay deducted from wages | Yes | Section 14(1)(a); no consent or clause required |
| Whole payslip taken to clear it | Yes in law | No statutory cap; the Royal College of Nursing calls this “often not reasonable” |
| Correct pay labelled as “overpayment” | No | No overpayment, so section 14 cannot apply; section 13 claim |
| Higher rate written in your contract | No clawback | That is contract performance, not an error |
| Holiday taken in excess, no contract clause | Usually no | Needs a relevant agreement under Working Time Regulations reg 14(4) |
Why the tribunal cannot decide if the sum is right
This is the trap. Workers go to tribunal expecting a judge to audit payroll. The tribunal will not do it.
Under Sunderland Polytechnic v Evans [1993] and SIP (Industrial Products) Ltd v Swinn [1994], the employment tribunal asks only two questions: was there an overpayment, and was the employer genuinely trying to recover it? If yes to both, the claim fails. Fairness, correct amount, contractual right to deduct and hardship are all outside its remit.
A paramedic learned this in Martin-Harris v West Midlands Ambulance Service University NHS Foundation Trust (2024). Final pay was docked £3,415.53 for an “hours deficit” caused by payroll design. The tribunal held section 14(1)(a) applied and dismissed the claim. If you dispute the figure itself, your route is a contract or restitution claim in the county court, or sheriff court in Scotland, not the tribunal.
Was there really an overpayment?
Start here, because everything turns on it. Check your contractual hourly rate, any enhancements for nights or weekends, your actual hours from rotas or clock data, and what landed in your bank net of tax.
Common non-overpayments we see in care, NHS bank and agency work: a booking confirmation that really did offer the higher rate, back pay after a late pay rise, arrears for travel time between care visits, or holiday pay that looks extra but is owed under holiday pay rules. If the paper says the higher figure, paying it is performance of the contract. There is nothing to claw back.
Example: Ana, care worker paid twice for one week
Ana works 32 hours at £12.71, the National Living Wage. That is £406.72 gross for the week. Payroll runs the file twice, so she receives an extra £406.72 gross. After 20% tax and 8% National Insurance, about £292.84 extra hits her bank. Ana should repay £292.84, not £406.72. Her employer recovers the £113.88 of tax and National Insurance through payroll. The employer can deduct the £293 net from her next payslip in law, but a one-off deduction is reasonable practice here because the sum is small and recent.
Example: Daniel, agency picker paid at the wrong rate
Daniel is booked at £12.71 but paid £14.21 for four weeks of 37.5 hours. That is 150 hours times £1.50, a £225 gross overpayment, about £162 net. If his only income sits at minimum wage, a lump deduction is still lawful for minimum wage purposes, but it would wipe out a week. He should ask for £30 to £40 a week over five to six weeks. First he checks the booking confirmation. If it said £14.21, there is no overpayment at all and any deduction is an unlawful deduction claim.
Example: Priya, NHS bank nurse overpaid for six months
Priya is paid the wrong band, £150 net a month too much for six months. She owes £900. The trust proposes taking £900 from a £1,600 payslip, leaving £700 and a bounced rent payment. Lawful under section 14, but poor practice. Royal College of Nursing and Acas guidance says to agree a repayment plan, and payroll guidance says to spread recovery over the same period the error built up: six payments of £150. Priya writes back asking for a full breakdown, a staged plan, and a copy of the trust overpayment policy, because many NHS policies bind the employer to staged recovery.
When you can resist paying it back at all
Most workers will have to repay something. These are the narrow routes out. They are hard, they need evidence, and they run in the civil courts, not as fairness pleas at tribunal.
Change of position
The lead authority is Lipkin Gorman v Karpnale Ltd [1991], applied to an overpaid pension in Scottish Equitable v Derby [2001]. If you received money in good faith and, because you had it, spent it in a way you otherwise would not have, you need not repay to that extent. A holiday booked because you thought the rise was real or a gift made: potentially relevant. Paying down your own debts is unlikely to count. Ordinary bills, food and rent: not relevant. You still pay day-to-day living costs anyway.
Estoppel
Avon County Council v Howlett [1983] stops an employer reclaiming where it represented the pay as correct, you relied on that and changed your position, and it would now be inequitable to demand repayment. Good faith plus real detrimental reliance is required. It rarely succeeds. Do not bank on it without legal advice.
Time limits on recovery
An employer suing an ex-worker for repayment has six years in England and Wales under the Limitation Act 1980, and six years in Northern Ireland under the Limitation (Northern Ireland) Order 1989. In England and Wales, section 32(1)(c) of the 1980 Act can delay the start of that clock for a payment made by mistake until the employer discovers the mistake or could with reasonable diligence have done so, so an old error is not automatically safe. In Scotland, claims based on unjustified enrichment and on contract prescribe after five years under the Prescription and Limitation (Scotland) Act 1973, but when the clock starts can turn on the facts, so get Scottish advice.
Can the deduction take you below minimum wage?
Yes. This is where workers feel the second shock.
Regulation 12(2)(c) of the National Minimum Wage Regulations 2015 says deductions “as respects an accidental overpayment of wages” do not reduce minimum wage pay. HMRC confirms this in its manual at NMWM11140, whether you repay by deduction or by bank transfer. The employer can lawfully leave you with almost nothing that week and still comply with minimum wage law.
Check your rate with our minimum wage rates guide. Your protection here is negotiation, not the wage floor. Ask for instalments that keep you able to eat, travel to work and pay rent, and put the hardship reasons in writing.
How to get a repayment plan you can live with
There is no statutory maximum for a single deduction. The whole of a final payslip can lawfully be taken. What you have instead is strong guidance that employers ignore at reputational risk.
Acas, updated 1 October 2026, says the employer should tell you before deducting, act flexibly and fairly, and agree a repayment plan for large or long-running overpayments. The Royal College of Nursing puts it more bluntly: full deduction from next wages is allowed “in law” unless your contract says otherwise, but “often not reasonable”. Payroll professional body CIPP says recover over the same period the error built up and avoid causing hardship.
- Ask for the policy. Many NHS trusts, councils and large care providers have an overpayment procedure that requires staged recovery and hardship review. That policy can bind them.
- Offer figures. Propose the same rhythm as the error: six months overpaid means six months to repay. Show your budget in two lines: rent, bills, travel to work.
- Get it signed. Amount owed net, instalment amounts and dates, no interest, corrected payslips and payroll correction confirmed. If they refuse any plan, keep that refusal. It matters if this ever reaches a court.
Leaving, final pay and too much holiday
Two different rules get tangled on the last payslip. Unpick them.
Final wages: a genuine wage overpayment can still be deducted from final pay under section 14(1)(a), in full. If you have left and there is nothing left to deduct from, the employer must ask you to pay and then sue in the county court if you refuse. That claim usually sits in the small claims track under £10,000.
Holiday taken in excess is different. Regulation 14(4) of the Working Time Regulations 1998 says you only compensate the employer for leave taken beyond what you accrued if a “relevant agreement” says so. That means a contract term, workforce agreement or collective agreement. Without that clause, docking final pay for extra holiday is an unlawful deduction. With a clause, many employers label it an “overpayment” and rely on section 14 anyway, which usually succeeds at tribunal.
Example: holiday in excess on leaving
You leave on 30 June with a 28-day entitlement for a January to December year. You accrued 14 days but took 20, so 6 days excess. On a £24,000 salary, a day is £24,000 divided by 260, about £92.31. Six days is £553.85. Your employer can deduct that from final pay only if your contract has a repayment clause. Without one, the deduction is unlawful and you have six months to claim, while the employer must sue you separately if it wants the money.
If your final pay is late or missing altogether, see when final pay must be paid.
Tax: repay the net, not the gross
You repay only what landed in your bank. The employer recovers the tax and National Insurance through payroll.
Same tax year: the employer adjusts year-to-date gross figures on the next Full Payment Submission. Previous tax year: the employer submits a revised final submission with corrected year-to-date values. Check your personal tax account after the correction. HMRC’s “negative earnings” tax relief route does not apply here; it expressly excludes repayments caused by error and covers contractual clawbacks like repaid bonuses instead.
Universal Credit: the double hit
This one ruins budgets. The overpayment is reported through payroll, Universal Credit treats it as earnings and cuts your award, then the employer claws the same money back. You lose twice for money you never truly earned.
Take a £400 inflated payslip. Universal Credit applies the 55% taper, so you lose £220 that assessment period. When the employer later deducts £400 net, you end up £220 worse off than before the error, for money you never really had. Child Poverty Action Group guidance says an overpayment subject to an immediate duty to repay is not earned or unearned income at all and should be treated as capital, disregarded entirely if total capital is under £6,000. DWP staff do not always apply this, and advisers have needed pre-action letters for judicial review to force a correction.
If this hits you, dispute the reported earnings with DWP, ask for mandatory reconsideration, and get a welfare adviser involved fast. See working while claiming Universal Credit. Keep the employer overpayment letter: it is your evidence that the money was never yours.
Scotland and Northern Ireland
Scotland follows the same core rules: the 1996 Act and the Working Time Regulations apply, the six-month tribunal deadline from 1 October 2026 applies, and civil recovery goes through the sheriff simple procedure for claims to £5,000. Get Scottish advice on time limits for old overpayments.
Northern Ireland is separate law. The Employment Rights (Northern Ireland) Order 1996 applies instead: article 45 bans unauthorised deductions, article 46(1)(a) gives the same overpayment exception, and holiday clawback sits in regulation 17 of the Working Time Regulations (Northern Ireland) 2016. The tribunal deadline stays at three months, early conciliation runs through the Labour Relations Agency not Acas, and the Employment Rights Act 2025 changes do not extend there.

Deadlines and what changed in 2026
- Statutory Sick Pay from day one
Lower earnings limit removed. Matters where payroll errors touch sick-pay weeks.
- Fair Work Agency established
HMRC still investigates minimum wage on its behalf. Wider holiday-pay and sick-pay enforcement powers are scheduled, not yet tested.
- Deduction claims move to six months
Employment Rights Act 2025 extends employment tribunal limits, including section 23 deduction claims, from three to six months. Acas early conciliation still pauses the clock. The two-year backstop on how far back deductions can go survives.
- Unfair dismissal qualifying period drops
Scheduled fall to six months, with the compensatory cap removed. This changes the balance of power if you are threatened with dismissal for disputing repayment. See why 1 January 2027 matters.
Questions people ask
Do I have to pay it back if the mistake was theirs?
Usually yes, if you were genuinely overpaid. The employer’s error does not cancel the debt. Your power is over how fast you repay, over tax corrections, and over proving whether an overpayment happened at all.
Can they take the whole amount in one go?
In law, yes. There is no cap on a single deduction. In practice, Acas, the Royal College of Nursing and payroll guidance all say large or long-running overpayments should be repaid in instalments. Put a staged offer in writing and cite any employer policy.
What if I already spent the money?
You may still owe it. Change of position helps only if you spent in good faith on something exceptional because you believed the money was yours. Ordinary living costs do not count. Get advice and gather receipts before relying on this.
Will repaying affect my tax?
It should not cost you tax if payroll corrects it. Repay the net sum only and ask the employer to fix the Full Payment Submission and give you corrected payslips. Check your personal tax account afterwards.
What if I have left the job?
They can deduct from any final pay due. If that does not cover it, they must ask you to pay and then bring a county court or sheriff court claim. You can still dispute whether you were overpaid, and holiday clawback still needs a contract clause.
How long do I have to challenge a deduction?
Six months from the deduction in Britain, after Acas early conciliation, since 1 October 2026. Three months in Northern Ireland after Labour Relations Agency conciliation. Do not wait: tribunal queues are long, with 64,000 single claims open in early 2026, up 55% in a year, and deduction claims are about 13% of all jurisdictional complaints.
