The phrase “HMRC wage raid payroll checks” is commonly used to describe intensive payroll or minimum-wage compliance checks, although “wage raid” is not the official term used by HMRC. Official guidance refers instead to National Minimum Wage checks, compliance checks, investigations and workplace visits.
In 2026, the enforcement landscape changed significantly. The Fair Work Agency (FWA) launched on 7 April 2026 under the Employment Rights Act 2025, bringing several labour-market enforcement functions together.
For National Minimum Wage enforcement, however, HMRC continues to carry out checks on behalf of the FWA, with the full transfer of this function planned for April 2027.
Employers still need accurate PAYE and Real Time Information records, but payroll compliance is now part of a broader move towards joined-up, risk-based and intelligence-led labour-market enforcement.
The FWA’s 2026–27 delivery plan specifically includes strengthening data, technology and intelligence capabilities to make enforcement more targeted and effective.
For businesses, this means payroll compliance should cover not only PAYE reporting but also minimum-wage calculations, working hours, deductions and sufficient supporting records.
How Does HMRC Conduct Payroll Checks Today?
HMRC payroll compliance increasingly relies on information submitted digitally through PAYE and Real Time Information (RTI). Employers normally need to submit a Full Payment Submission (FPS) on or before the date employees are paid, giving HMRC up-to-date information about wages, Income Tax and National Insurance.
For National Minimum Wage investigations, HMRC says employers may be selected following its own research or after a complaint about possible underpayment. Official enforcement guidance also allows targeted investigations using risk modelling and third-party information.
This is now linked to the wider Fair Work Agency enforcement framework. The FWA has statutory responsibility for minimum-wage enforcement, while HMRC officers continue to deliver this work on its behalf during 2026–27. The FWA is developing a more joined-up and intelligence-led approach, including better use of data, technology and AI-supported systems.
A check can involve requests for payroll records, explanations of how pay has been calculated and information about employees’ working arrangements. HMRC may also speak to workers where it needs additional evidence to establish whether the correct minimum wage has been paid.
What Are Employers’ Responsibilities Under HMRC Payroll Checks?
Employers are legally responsible for ensuring that every worker is paid fairly and that payroll data is accurately reported to HMRC. A failure to comply, even unintentionally, can lead to significant financial and reputational consequences.
One of an employer’s most important obligations is ensuring eligible workers receive at least the applicable National Minimum Wage or National Living Wage.
From 1 April 2026, the statutory hourly rates are:
- £12.71 for workers aged 21 and over
- £10.85 for workers aged 18 to 20
- £8.00 for workers under 18 who are above compulsory school-leaving age
- £8.00 for qualifying apprentices
The National Living Wage therefore increased from £12.21 in 2025/26 to £12.71 in 2026/27.
Employers also need to consider deductions and unpaid working time carefully. Items such as uniforms, required expenses and some salary-sacrifice arrangements can affect whether a worker has actually received the statutory minimum for the relevant pay reference period.
Record retention also needs clarification. Ordinary PAYE payroll records generally need to be kept for three years from the end of the tax year they relate to, but records demonstrating compliance with the National Minimum Wage must generally be retained for at least six years.
These records commonly include total pay, deductions, hours worked and supporting information explaining how minimum-wage entitlement was calculated.
What Should Employees Do When Payroll Discrepancies Are Found?
While much of HMRC’s attention focuses on employers, employees also play a vital role in ensuring payroll integrity. Workers are encouraged to take an active interest in how their pay is calculated and to report any potential errors or underpayments promptly.
Every employee should regularly review their payslip, checking for inconsistencies such as incorrect tax codes, missing overtime pay, or unexplained deductions. A small numerical error can easily snowball into larger issues if left unreported.
HMRC provides several digital tools to help employees check their pay. The Check Your Pay service on GOV.UK allows workers to calculate whether they are being paid at or above the correct NMW or NLW rate based on their age and working hours.
If an employee suspects underpayment, they can report the issue confidentially to HMRC or seek assistance from Acas (Advisory, Conciliation and Arbitration Service). In more serious cases, employees can also bring formal claims through an employment tribunal.
Consider a practical example: a barista in Birmingham noticed her hourly rate was slightly below the new 2025 National Living Wage. After using the Check Your Pay calculator and confirming the discrepancy, she contacted Acas for advice.
HMRC later investigated and required the café owner to adjust all wages and repay the difference to affected employees.
The key message for employees is clear: staying informed and proactive ensures fair pay and strengthens workplace transparency.
What Triggers an HMRC Wage Raid or Payroll Investigation?
There is no single trigger for an HMRC payroll or minimum-wage investigation. HMRC says checks can begin because of its own research or because it has received a complaint alleging that one or more workers have been paid below the statutory minimum.
Targeted minimum-wage investigations may also make use of risk modelling, third-party information and other intelligence. This means an investigation does not necessarily require an employee complaint before HMRC can act.
Potential warning signs can include inconsistent wage and working-hour records, unexplained deductions, incorrect minimum-wage calculations or payroll information that does not adequately support the amounts employees were paid.
The Fair Work Agency has also adopted a risk-based enforcement approach, with proactive activity particularly relevant where sectors or situations are considered high risk. Its 2026–27 strategy aims to improve joined-up intelligence so enforcement can be better targeted.
Employers should therefore avoid assuming that only large businesses or companies that have received complaints will be checked.
What Happens During an HMRC Payroll Inspection or Wage Raid?
The term “wage raid” can make every HMRC check sound like an unexpected search, but official guidance describes a more varied process.
HMRC may first ask an employer to provide information or records. Where a workplace visit is necessary, HMRC states that it will normally try to arrange an appointment at a suitable time.
However, minimum-wage enforcement officers also have statutory powers that can allow them to enter business premises, inspect documents and check computer systems where required for enforcement purposes.
During a visit, officers may discuss employees’ working patterns and the employer’s methods for calculating pay. They can examine payroll and wage records, take copies and request further explanations. Workers may also be contacted where their evidence is necessary to establish actual hours, pay arrangements or other facts.
When the check is completed, HMRC tells the employer that the investigation has ended. If underpayment is identified, the employer can receive a Notice of Underpayment, setting out wage arrears and any financial penalty that must be paid.
Deliberate, repeated or serious breaches can lead to stronger enforcement, including Labour Market Enforcement undertakings or orders and, in the most serious cases, criminal proceedings.
What Are the Penalties and Consequences for Non-Compliance?
Non-compliance with payroll and tax regulations carries serious repercussions. HMRC has legal authority to issue financial penalties, demand repayment of arrears, and publicly identify offending employers.
The following table outlines typical breaches and corresponding penalties:
| Type of Non-Compliance | Current Position |
|---|---|
| National Minimum Wage underpayment | Penalty generally calculated at 200% of underpayment |
| Maximum NMW penalty | Up to £20,000 for each worker |
| Minimum NMW penalty | £100 per Notice of Underpayment where applicable |
| Prompt payment | Penalty can be reduced by 50% if all arrears and 50% of the penalty are paid within 14 days |
| Late RTI filing – 1 to 9 employees | £100 |
| Late RTI filing – 10 to 49 employees | £200 |
| Late RTI filing – 50 to 249 employees | £300 |
| Late RTI filing – 250+ employees | £400 |
| Persistent RTI failure beyond 3 months | A further penalty of 5% of the relevant PAYE/NIC liability may apply in serious cases |
| Serious or deliberate NMW breaches | Civil enforcement, labour-market enforcement action or possible criminal proceedings |
The first late RTI filing failure in a tax year is normally not penalised, except for annual PAYE schemes, and additional rules apply to new employers.
For minimum-wage breaches, the current penalty can reach 200% of arrears, capped at £20,000 per worker. Paying all worker arrears and half of the penalty within 14 days can reduce the penalty by 50%.
The scale of current enforcement was demonstrated in March 2026, when the government named 389 employers for minimum-wage breaches affecting around 60,000 workers.
Employers were required to repay more than £7.3 million in wages, alongside approximately £12.6 million in penalties.
How Can Employers Prevent Payroll Compliance Problems Before They Start?
The best defence against HMRC wage raid payroll checks is consistent, transparent payroll management. Employers who maintain proper records, pay fairly, and file accurate reports have little to fear from compliance visits.
Preventive measures include conducting internal payroll audits at least quarterly to identify discrepancies before HMRC does. Employers should also ensure that payroll staff and HR teams are properly trained on current NMW/NLW rates and employment tax regulations.
Using digital payroll software approved by HMRC can further minimise the risk of human error. These systems automatically calculate deductions, generate payslips, and prepare RTI submissions, reducing the chance of manual mistakes.
Engaging a qualified accountant or payroll advisor is another valuable safeguard. Professionals can conduct periodic reviews, ensure compliance with legislation updates, and provide support if a compliance check is initiated.
The investment in professional payroll management not only reduces the likelihood of penalties but also fosters trust between employers and employees, contributing to a healthier, more transparent workplace culture.
What Should Businesses Do If HMRC Flags a Discrepancy?
When HMRC detects a discrepancy, it usually notifies the employer in writing. The notice will explain the issue and request specific documentation or explanations. Businesses should respond promptly and provide the requested information in full.
If an error has been made, it’s often better to admit and correct it voluntarily. HMRC tends to take a more lenient stance toward employers who cooperate and demonstrate genuine efforts to comply.
In more complex cases, legal or financial advice may be necessary to navigate negotiations with HMRC and ensure that any back payments or penalties are handled correctly. Maintaining open communication and professional conduct throughout the process is key to minimising damage.
Conclusion
HMRC payroll and minimum-wage checks remain an important compliance risk for UK employers in 2026, but the enforcement landscape is also changing.
Since 7 April 2026, the Fair Work Agency has held statutory responsibility for National Minimum Wage enforcement as part of a wider effort to create more joined-up, risk-based labour-market enforcement.
HMRC continues to conduct minimum-wage investigations on the agency’s behalf during 2026–27, with the function scheduled to transfer fully to the FWA from April 2027.
For employers, the most important safeguards remain straightforward: apply the correct £12.71 National Living Wage and other 2026 minimum-wage rates, report payroll information correctly through RTI, account properly for working time and deductions, and retain adequate records.
Businesses should also avoid treating “wage raids” as something that only happens after a worker complaint. Current enforcement can be intelligence-led and risk-based, and HMRC has powers to investigate where its own research indicates possible non-compliance.
Accurate payroll records and regular internal checks are therefore increasingly important as UK labour-market enforcement becomes more coordinated and data-driven.
