HMRC Wage Raid Payroll Checks: What UK Employers Need to Know?

HMRC wage raid payroll checks are compliance investigations used to establish whether employers are paying workers correctly and keeping the records needed to prove compliance.

Despite the dramatic phrase “wage raid”, a National Minimum Wage check does not always begin with inspectors arriving unexpectedly at a workplace.

A check can begin when an employer is first contacted and may involve requests for payroll information, explanations of wage calculations, discussions with workers and, where necessary, a workplace visit.

Employers should also distinguish National Minimum Wage enforcement from PAYE and Real Time Information checks. Payroll records may be relevant to both, but minimum wage compliance and PAYE tax reporting are separate legal issues with different rules, penalties and record-keeping requirements.

What Are HMRC Wage Raid Payroll Checks?

“Wage raid” is mainly shorthand used to describe enforcement activity involving workers’ pay. The formal process is generally a compliance check into whether employees and workers have received at least the legal minimum wage.

A check can examine:

• Hourly Pay
• Hours Actually Worked
• Payroll Records
• Timesheets
• Employee Deductions
• Uniform And Equipment Costs
• Training Time
• Travel Between Work Locations
• Apprentice Pay
• Age-Related Rate Changes
• Accommodation Provided By The Employer

A physical visit is possible, but it should not be assumed that every investigation begins without notice. Where a visit is required, officers will normally try to arrange an appointment, although legal powers are available where access or information is refused.

What Changed for Wage Enforcement in 2026?

The enforcement environment changed significantly during 2026.

The Fair Work Agency began operating on 7 April 2026 as part of the wider Employment Rights Act 2025 reforms. During 2026, HMRC continues to enforce National Minimum Wage requirements while working in partnership with the new agency.

Further integration is planned from April 2027, when National Minimum Wage enforcement staff are expected to transfer into the Fair Work Agency.

Enforcement activity has also remained highly visible.

On 19 March 2026, 389 employers were named following minimum wage breaches affecting around 60,000 workers. More than £7.3 million in unpaid wages had to be repaid, while penalties totalled £12.6 million.

Another naming round followed on 3 September 2026, when nearly 660 employers were announced as having underpaid around 27,000 workers, with approximately £4 million returned to employees.

These cases demonstrate that minimum wage enforcement is not limited to large corporations. Small businesses can also face checks, arrears, penalties and public naming.

What Are the Minimum Wage Rates for 2026?

The statutory rates increased in April 2026.

Worker Category	From April 2026	Previous Rate
Age 21 And Over	£12.71	£12.21
Age 18 To 20	£10.85	£10.00
Age 16 to 17	£8.00	£7.55
Apprentice Rate	£8.00	£7.55
Accommodation Offset Per Day	£11.10	£10.66

Employers need to be careful about when the increase applies. The new rate becomes payable from the first pay reference period beginning on or after 1 April, rather than automatically changing every worker’s pay calculation at midnight on 1 April.

The same principle matters when an employee reaches an age that moves them into a higher minimum wage band.

What Can Trigger a Minimum Wage Check?

An investigation can begin because of enforcement research or because a worker reports a possible underpayment. A complaint can therefore be enough to bring an employer’s wage arrangements under examination.

Workers can report suspected minimum wage underpayment anonymously, including after leaving the business. Employers should never assume that a former employee can no longer raise concerns about historical pay.

Possible risk areas include:

• Workers Being Paid Close To The Statutory Minimum
• Unusual Payroll Deductions
• Incorrect Apprentice Rates
• Missing Working-Time Records
• Unpaid Training
• Unrecorded Additional Hours
• Incorrect Age-Band Changes
• Salary Sacrifice Affecting Minimum Wage Pay

Separate PAYE or RTI problems can also lead to payroll questions, but these should not automatically be described as minimum wage breaches.

What Happens During a Minimum Wage Compliance Check?

The check starts from the date the employer is first contacted.

Officers may request information before deciding whether a physical visit is required. During the investigation, the employer may need to explain how working hours and wages have been calculated.

A typical review may involve:

1. Examining Payroll And Wage Records
2. Checking Working Hours And Timesheets
3. Reviewing Employment Agreements
4. Examining Deductions And Worker Expenses
5. Checking Apprentice And Age-Related Rates
6. Speaking With Payroll Staff Or Management
7. Speaking Directly With Workers
8. Requesting Additional Evidence Where Figures Do Not Match

What Documents Should Employers Have Ready?

Record	Why It Matters
Payroll Records	Shows gross pay and wage calculations
Payslips	Confirms amounts provided to workers
Timesheets	Demonstrates hours actually worked
Employment Contracts	Shows agreed pay and working arrangements
Deduction Records	Identifies amounts removed from wages
Training Records	Helps establish whether training time counts as work
Apprentice Records	Confirms the correct apprentice rate
Accommodation Records	Supports accommodation offset calculations
RTI Records	Supports separate PAYE reporting checks

Good payroll software helps organise information, but software itself does not prove compliance if the underlying hours, deductions or employee classifications are wrong.

Where Do Minimum Wage Underpayments Commonly Hide?

Many minimum wage breaches are calculation mistakes rather than an employer simply setting an hourly rate below the legal minimum.

Uniforms, Tools And Equipment

If workers are required to buy specific clothing, uniforms, tools or equipment for their job, those costs can reduce their pay for minimum wage purposes.

A worker apparently receiving £13 an hour could therefore fall below the £12.71 rate after a qualifying deduction.

Unpaid Working Time

Pre-shift preparation, closing duties and other required work can increase the number of hours that must be included in the calculation.

Required training may also count as working time.

Travel Between Work Locations

Ordinary commuting between home and work normally does not count. Travel required between assignments, workplaces or work-related training locations can be different.

Salary Sacrifice

Salary sacrifice arrangements need checking because reducing contractual pay can create a minimum wage problem even where the overall employee benefit package appears attractive.

Birthdays And Age Bands

An employee moving into a higher age band may become entitled to a higher rate from the appropriate following pay reference period.

Apprentices

The apprentice rate normally applies to apprentices under 19 and those aged 19 or over who are still in the first year of their apprenticeship. Older apprentices who have completed their first year generally move to the rate applicable to their age.

What Happens If an Employer Has Underpaid Workers?

An employer found to have underpaid workers can be required to repay the arrears and may receive a Notice of Underpayment.

Importantly, historic arrears are not necessarily calculated simply using the old hourly rate. The calculation can uplift an old underpayment using the current minimum wage rate for the relevant wage band.

That means an error from an earlier year may cost more to correct later.

Minimum Wage Penalties

The financial penalty is normally calculated at 200% of the underpayment.

The main limits are:

Rule	Amount
Penalty Rate	200% Of Underpayment
Minimum Penalty	£100 Per Notice
Maximum	£20,000 Per Worker

Current enforcement rules also provide for a 50% reduction where the employer fully complies with the terms of the notice within 14 days. Employers should check the notice they actually receive before relying on that reduction.

Can an Employer Appeal a Notice of Underpayment?

Yes.

An appeal normally has to be made to an employment tribunal within 28 days of the date the notice is treated as given.

An employer can challenge:

• The Decision To Issue The Notice
• The Amount Owed To A Worker
• The Financial Penalty

For delivery purposes, a notice handed over personally is generally treated as given that day. An email sent before 4:30pm is generally treated as given the same day, while one sent later is treated as given the following day. A posted notice is normally treated as given two working days after its date.

Collection of the penalty is suspended while a valid appeal is being considered.

Can a Business Be Publicly Named?

Yes. Public naming is separate from repaying workers and paying the financial penalty. Businesses can generally be considered for naming where total minimum wage arrears are £500 or more.

A lower threshold of more than £100 can apply in certain cases involving previous notices, relevant previous offences or existing labour market enforcement action.

Being a small company or saying the breach was accidental does not automatically prevent naming.

What Rights Does an Employer Have During a Visit?

Employers should cooperate, but that does not mean they need to handle the process without professional support.

A business can authorise an adviser or other representative to assist during the check.

Employers should:

• Confirm Who Is Conducting The Check
• Understand What Information Has Been Requested
• Keep Copies Of Documents Supplied
• Provide Accurate Explanations Rather Than Guessing
• Correct Genuine Mistakes Promptly
• Keep A Record Of Important Communications

Officers can inspect relevant records, speak to people with useful information and take copies of documents. Intentionally obstructing enforcement activity or deliberately refusing required information can create much more serious problems.

How Should Employers Carry Out a Payroll Self-Audit?

A simple quarterly payroll review can identify many problems before they become enforcement issues.

Check that:

• Every Worker Is On The Correct 2026 Rate
• Employee Birthdays Are Monitored
• Apprentices Move Rate When Required
• All Working Time Is Recorded
• Required Training Is Included Where Necessary
• Travel Between Work Locations Is Reviewed
• Uniform And Equipment Costs Are Checked
• Salary Sacrifice Does Not Reduce Pay Below The Minimum
• Accommodation Offset Calculations Are Correct
• Payroll Corrections Are Documented
• RTI Reports Match Payroll Records
• Historic Underpayments Are Corrected Promptly

Businesses employing workers close to minimum wage should carry out these checks more frequently because even a relatively small deduction can create an underpayment.

How Are PAYE And RTI Checks Different?

PAYE compliance deals with whether the correct tax, National Insurance and other payroll deductions have been calculated, reported and paid.

Employers normally report pay through a Full Payment Submission and pay amounts due by the 22nd of the following tax month when paying electronically, or the 19th when paying by post.

Businesses that usually pay less than £1,500 per month may be allowed to make quarterly payments.

Late PAYE payments can attract daily interest and penalties. Late or incorrect RTI reports can also create problems for employees whose tax or income-related benefits depend on payroll information.

Employees can sometimes discover PAYE discrepancies when their tax position is later reconciled, which is why understanding how HMRC PAYE refund letters work can also be useful.

Employers planning further ahead should also be aware of the planned PAYE tax deduction reforms from 2029, which could create additional payroll administration for affected workers.

HMRC Wage Raid Payroll Checks: What UK Employers Need to Know in 2026

Minimum wage and PAYE records should not be treated as having the same retention period.

Record Type	General Retention Period
National Minimum Wage Records	At Least 6 Years
PAYE Records	At Least 3 Years After The Relevant Tax Year

Separate tax assessment rules can allow tax matters to be examined over different periods, including 4, 6 or 20 years depending on the circumstances. Those assessment time limits should not be confused with the statutory minimum wage record-keeping rule.

Conclusion

HMRC wage raid payroll checks should be treated primarily as a minimum wage compliance issue rather than assuming every check is an unannounced PAYE raid.

For employers, the biggest risks often sit inside ordinary payroll processes: unpaid working time, required clothing, deductions, training, travel, salary sacrifice, apprentice rules and missed age-band changes.

With the National Living Wage at £12.71 for workers aged 21 and over in 2026, stronger enforcement activity and the Fair Work Agency now operating, businesses have more reason than ever to review payroll before an investigator finds the problem.

Accurate records, regular wage audits and prompt correction of mistakes remain the strongest practical protection.

Frequently Asked Questions

Can HMRC Visit My Business Without Warning?

Officers have powers to conduct minimum wage checks and enter business premises in appropriate circumstances. However, current procedures say they will normally try to arrange a suitable appointment when a visit is required.

Can an Employee Complaint Start a Wage Check?

Yes. A complaint that workers may be receiving less than the legal minimum can trigger an investigation. Reports can also be made anonymously by former workers.

How Far Back Can Payroll Records Be Checked?

Employers generally need to retain minimum wage records for at least six years, while PAYE records generally have a three-year retention requirement. Separate tax assessment time limits can be longer.

Does Using Payroll Software Protect My Business From Penalties?

No. Payroll software can calculate and report information, but it cannot prevent errors caused by incorrect working hours, deductions, apprentice status, age information or other inaccurate inputs.

What Should I Do If I Discover a Minimum Wage Underpayment?

Calculate the affected pay periods carefully, correct the underpayment as quickly as possible and keep evidence showing how the correction was calculated and paid. Repeated or widespread errors should be reviewed professionally.
