[How each figure is worked out](/methodology/). The Public Sector Fraud Authority estimates fraud and error in government at **£51.3bn to £81.0bn** in 2022/23, including tax and welfare. The Department for Work and Pensions estimates that **3.2% (£9.9bn)** of benefit spending was overpaid in the financial year ending 2026. Separately, each department discloses its losses and special payments in its accounts; for the ten largest they are set out below. Figures are quoted as published. ## Key figures - £51.3bn to £81.0bnEstimated fraud and error in government £39.8bn to £58.5bn in 2021/22 2022/23 - 3.0% to 4.8%Of all government spending and income 2022/23 - 3.2% (£9.9bn)Of benefit spending overpaid financial year ending 2026 - £1.7bnFraud and error detected and reported to the PSFA 2023/24 - £914mPrevented and recovered by departments in scope 2023/24 ## What is the short version? - **An estimate, not a count:** most fraud and error is never detected, so the figures are extrapolated from samples and published as ranges. The amount actually detected and reported was £1.7bn in 2023/24. - **Fraud and error are different:** fraud is deliberate; error is a mistake by the claimant or the official, and includes underpayments. - **Write-offs are not fraud:** departments’ losses include cash lost, debts written off and spending on things that were then not used; special payments include compensation. - **The departments’ figures cannot be added up or ranked:** each counts cases and draws its boundary differently. - **The tax gap (6.4% (£59.2bn), 2024 to 2025) is context, not spending:** it is tax that should have been paid but was not, for any reason. ## How much is lost to fraud and error? **Estimated fraud and error in government: the low and high ends of each range** - 1. 2021/22, low end £39.8bn - 2. 2021/22, high end £58.5bn - ◆3. 2022/23, low end £51.3bn - ◆4. 2022/23, high end £81.0bn ◆ Latest estimate Both ends of each published range, outside COVID-19 schemes, including tax and welfare.

Estimates of fraud and error are ranges because most of it is never detected: they are extrapolated from samples and reviews. Fraud is deliberate; error is a mistake by the claimant or the official, and includes underpayments. The tax gap is tax that should have been paid but was not, for any reason, and is shown for context: it is not spending. 3.0% to 4.8% of overall government spending and income: the Public Sector Fraud Authority’s estimate of fraud and error in 2022/23, the same estimate as the range above. ### What do the sources say, in their own words? “Data for 2022/23 puts the estimated fraud and error in government between £51.3bn and £81.0bn, outside of COVID-19 schemes. This calculation includes tax and welfare” Public Sector Fraud Authority, Cross-Government Fraud Landscape Report 2022/23 and 2023/24 “In 2021/22 the PSFA estimated that the level of fraud and error was between £39.8bn and £58.5bn.” Public Sector Fraud Authority, Cross-Government Fraud Landscape Report 2022/23 and 2023/24 “between 3.0% and 4.8% of overall government expenditure and income” Public Sector Fraud Authority, Cross-Government Fraud Landscape Report 2022/23 and 2023/24 “£1.7bn of detected fraud and error reported to the PSFA in 2023/24” Public Sector Fraud Authority, Cross-Government Fraud Landscape Report 2022/23 and 2023/24 “in-scope departments prevented and recovered £914m of fraud and error in 2023/24” Public Sector Fraud Authority, Cross-Government Fraud Landscape Report 2022/23 and 2023/24 3.2% (£9.9bn) of benefit spending was overpaid in the financial year ending 2026, on the Department for Work and Pensions’ estimate; 0.4% (£1.2bn) was underpaid. “The total rate of benefit expenditure overpaid in FYE 2026 was 3.2% (£9.9bn), compared with 3.3% (£9.4bn) in FYE 2025.” Department for Work and Pensions, Fraud and error in the benefit system, FYE 2026 estimates “The total rate of benefit expenditure underpaid remained at 0.4% in FYE 2026 (£1.2bn)” Department for Work and Pensions, Fraud and error in the benefit system, FYE 2026 estimates “the provisional estimate of the UK tax gap in 2024 to 2025 is estimated to be 6.4% of total theoretical tax liabilities, or £59.2 billion” HM Revenue and Customs, Measuring tax gaps 2026 edition Source: [Public Sector Fraud Authority, DWP and HMRC, Fraud and error estimates](https://www.gov.uk/government/organisations/public-sector-fraud-authority), latest estimates. Checked 22 September 2026. ## What do departments write off? Every department must disclose in its annual accounts the money it has lost (cash lost, debts written off, spending on things that were then not used) and the special payments it made outside its normal rules, such as compensation and ex gratia payments. These are the ten largest departments’ latest disclosures. | Department | Year | Losses | Year before | Special payments | Year before | | --- | --- | --- | --- | --- | --- | | [Department for Work and Pensions](https://www.gov.uk/government/publications/dwp-annual-report-and-accounts-2025-to-2026)Details | 2025-26 | £522.4m1,275,438 cases | £480.3m1,100,830 cases | £11.9m10,672 cases | £6.1m11,640 cases | | Year2025-26Year before£480.3m1,100,830 casesSpecial payments£11.9m10,672 casesYear before£6.1m11,640 cases | | | | | | | [HM Revenue and Customs](https://www.gov.uk/government/publications/hmrc-annual-report-and-accounts-2025-to-2026)Details | 2025-26 | £188.3m481,522 cases | £382.2m743,926 cases | Not printed | Not printed | | Year2025-26Year before£382.2m743,926 casesSpecial paymentsNot printedYear beforeNot printed | | | | | | | [Ministry of Defence](https://www.gov.uk/government/publications/ministry-of-defence-annual-report-and-accounts-2025-to-2026)Details | 2025-26 | £1.23bn17,622 cases | £1.90bn18,982 cases | £168.6m7,080 cases | £110.7m5,225 cases | | Year2025-26Year before£1.90bn18,982 casesSpecial payments£168.6m7,080 casesYear before£110.7m5,225 cases | | | | | | | [Department of Health and Social Care](https://www.gov.uk/government/publications/dhsc-annual-report-and-accounts-2024-to-2025)Details | 2024-25 | £2.00bn158,000 cases | £9.09bn467,842 cases | £25.0m8,358 cases | £20.8m7,411 cases | | Year2024-25Year before£9.09bn467,842 casesSpecial payments£25.0m8,358 casesYear before£20.8m7,411 cases | | | | | | | [Home Office](https://www.gov.uk/government/publications/home-office-annual-report-and-accounts-2025-to-2026)Details | 2025-26 | £98.3m11 cases | £364.5m16 cases | £52.3m5,552 cases | £80.3m6,921 cases | | Year2025-26Year before£364.5m16 casesSpecial payments£52.3m5,552 casesYear before£80.3m6,921 cases | | | | | | | [Ministry of Justice](https://www.gov.uk/government/publications/ministry-of-justice-annual-report-and-accounts-2024-to-2025)Details | 2024-25 | £71.0m22,236 cases | £33.9m37,753 cases | £35.3m9,895 cases | £36.8m14,985 cases | | Year2024-25Year before£33.9m37,753 casesSpecial payments£35.3m9,895 casesYear before£36.8m14,985 cases | | | | | | | [Department for Education](https://www.gov.uk/government/publications/department-for-education-consolidated-annual-report-and-accounts-2024-to-2025)Details | 2024-25 | £34.9m62,866 cases | £46.4m56,908 cases | £2.8m1,763 cases | £3.5m1,571 cases | | Year2024-25Year before£46.4m56,908 casesSpecial payments£2.8m1,763 casesYear before£3.5m1,571 cases | | | | | | | [Cabinet Office](https://www.gov.uk/government/publications/cabinet-office-annual-report-and-accounts-2025-to-2026)Details | 2025-26 | £9.5m432 cases | £1.2m437 cases | £716,00025 cases | £527,00015 cases | | Year2025-26Year before£1.2m437 casesSpecial payments£716,00025 casesYear before£527,00015 cases | | | | | | | [Department for Transport](https://www.gov.uk/government/publications/dft-annual-report-and-accounts-2025-to-2026)Details | 2025-26 | £398.0m35,484 cases | £581.2m63,968 cases | £14.5m8,333 cases | £13.2m8,729 cases | | Year2025-26Year before£581.2m63,968 casesSpecial payments£14.5m8,333 casesYear before£13.2m8,729 cases | | | | | | | [Department for Energy Security and Net Zero](https://www.gov.uk/government/publications/desnz-annual-report-and-accounts-2025-to-2026)Details | 2025-26 | £41m176,463 cases | £133m515,980 cases | £10m1,539 cases | £5m2 cases | | Year2025-26Year before£133m515,980 casesSpecial payments£10m1,539 casesYear before£5m2 cases | | | | | | These cannot be added up or ranked.
