An HMRC wage raid payroll check is an unannounced or short-notice compliance visit in which HMRC officers inspect pay records, contracts, timesheets and RTI submissions to confirm every worker received at least the National Minimum Wage. Failing one costs 200% of the underpayment, capped at £20,000 per worker, plus public naming.
HMRC wage raid payroll checks are going to get intensified this year, and that’s a reality check you need to give to your clients. As a practice handling the payroll of your clients, it’s your responsibility to alert them about HMRC inspection of their payroll with little or no warning. If their records aren’t accurate, it can lead to penalties, backdated payments, and reputational risk.
Let’s understand this risk in an easy way.
A small hospitality business in the UK was running payroll in-house. Everything looked perfect, their employees were being paid, payslips were generated, and taxes were submitted on time.
Then one morning, HMRC gave a surprise visit.
Within days, the business discovered:
- Incorrect National Minimum Wage calculations
- Missing payroll records
- Inconsistencies in employee hours
The result?
- Fines, back payments, and a lot of stress.
The issue wasn’t intentional non-compliance but the lack of structured payroll processing structures.
According to HMRC data, thousands of businesses were investigated for payroll and wage compliance issues, particularly around the National Minimum Wage (NMW). It was discovered that 389 employers from across the UK were failing to pay workers the minimum wage to tens of thousands of workers. A total of around £12.6 million in penalties was recovered from them on top of the repaid wages.
That round was published on 19 March 2026 as Round 23 of the naming scheme. Alongside it, the Department for Business and Trade released an educational bulletin setting out exactly why those 389 employers failed — the data is broken down further down this page.
As an accounting practice handling the payroll of your clients, it’s your responsibility to ensure your clients do not fail in this compliance.
For that, we have prepared this guide in which we will cover:
- What HMRC wage raid payroll checks actually involve
- Why inspections are increasing
- Common triggers and red flags
- How to stay compliant
- And how outsourcing payroll can significantly reduce your risk
- The April 2026 NMW rates your clients must be paying right now
Key Takeaways
- Rates: From 1 April 2026, the National Living Wage is £12.71 (21+), £10.85 (18–20) and £8.00 (16–17 and apprentices).
- Penalty: 200% of the underpayment, minimum £100 per notice, maximum £20,000 per worker — halved if settled within 14 days.
- Look-back: Six years of records, with arrears recalculated at today’s rates, not the rates in force at the time.
- Biggest cause: Deductions, not low headline pay. 40% of the 389 employers named in March 2026 were caught this way.
- Who inspects: The Fair Work Agency launched 7 April 2026, but HMRC still runs NMW enforcement through 2026/27. Full transfer is expected in April 2027.
- For practices: One systematic error in a bureau template replicates across every client on it.
What Are HMRC Wage Raid Payroll Checks?
HMRC wage raid payroll checks are unannounced compliance visits where HMRC officers inspect a business’s pay records, employee contracts, and PAYE returns to verify that all workers are paid at least the National Minimum Wage (NMW) or National Living Wage (NLW), and that payroll is reported accurately to HMRC in real time.
“Wage raid” is media shorthand, not a legal term. HMRC calls these National Minimum Wage compliance checks or PAYE compliance reviews. Worth saying to a client: nothing is being seized, and a visit is not an accusation of fraud.
These visits happen without any advance notice and the goal of these checks is to see whether payroll records match what has been reported to HMRC.
Under these checks, the following things are scrutinised:
- Minimum wage compliance
- Payroll accuracy
- Real Time Information reporting
- Off-the-books workers
- National Insurance contributions
- Incorrect tax codes
- False employment status claims
- Deductions and salary sacrifice arrangements that reduce pay below the statutory floor
- Unpaid working time — pre-shift briefings, mandatory training, travel between sites, clock-in rounding
What Are the NMW and NLW Rates From April 2026?
The one new H2. It exists because the rates on the page are currently wrong, and because this is a high-volume question in its own right.
From 1 April 2026 the National Living Wage for workers aged 21 and over is £12.71 per hour. The 18–20 rate is £10.85, and the 16–17 and apprentice rates are both £8.00. Around 2.7 million UK workers are affected. Any employer still paying 2025/26 rates in a pay reference period starting on or after 1 April 2026 is already non-compliant.
| Age band /category | From 1 Apr 2026 | To 31 Mar 2026 | Increase |
| 21 and over (NLW) | £12.71 | £12.21 | +4.1% |
| 18 to 20 | £10.85 | £10.00 | +8.5% |
| 16 to 17 | £8.00 | £7.55 | +6.0% |
| Apprentice (under 19, or in year 1) | £8.00 | £7.55 | +6.0% |
| Accommodation offset (per day) | £11.10 | — | £77.70 weekly cap |
Source: GOV.UK — National Minimum Wage rates.
Two rules catch practices out more than the headline rate. First, the increase applies from the first pay reference period starting on or after 1 April, not from the pay date — a monthly period running 10th to 9th switches on 10 April. Second, a worker crossing 18, 20 or 21 moves up a band in the first pay reference period after their birthday, which makes birthday tracking a payroll control rather than an HR afterthought.
Why Are HMRC Wage Raid Payroll Checks Intensifying in 2026?
Checks are rising because enforcement gained better data and a wider mandate at the same time. RTI gives HMRC continuous visibility of hours and pay, the April 2026 uprating moved millions of workers onto new rates, and the Employment Rights Act 2025 created a single enforcement body. Naming rounds are now more frequent.
The increase in HMRC wage raid payroll checks or payroll inspections is not a sudden decision. As automation increased and the pay structure became complex, errors started happening. HMRC’s goal is to ensure that employees are paid on time and in line with the law.
Recent incidents have made HMRC more proactive in payroll inspections. Let’s understand them.
Focus on National Minimum Wage Compliance
According to HMRC, around 389 employers in the UK were found to be underpaying their employees, which was negatively impacting around 60,000 workers. HMRC recovered around £12.6 million in penalties from these employers on top of the repaid wages.
To ensure such non-compliance does not happen again, HMRC is actively conducting wage raid payroll checks to ensure compliance.
Increased Digital Monitoring
With real-time information (RTI) submissions and the Making Tax Digital expansion towards Income tax. HMRC will have better access to data and will be able to monitor payments and spot discrepancies within hours.
Government Crackdown on Non-Compliance
The UK government has increased efforts to:
- Identify underpaid workers
- Companies that file late payroll submissions
- Find out businesses that previously received penalties
- Emphasis on complaints from workers
HMRC has started naming and shaming businesses that pay wages below the national minimum wage standards. The message is clear: Payroll compliance is now under constant scrutiny.
What Triggers an HMRC Payroll Inspection?
HMRC selects businesses through risk profiling of RTI data, worker complaints, sector-wide enforcement campaigns and prior non-compliance history. A single anonymous complaint is enough to open a check — workers can report underpayment without giving their name, and every complaint is reviewed.
Most of the HMRC wage raid payroll checks are triggered when the regulator notices specific warning signs.
These warning signs are:
Inconsistent PAYE Submissions
When frequent errors or irregularities are noticed in the RTI submissions, it will immediately raise a red flag among HMRC officers and make your client a target of frequent checks.
National Minimum Wage Risks
In recent years, HMRC has found many businesses not following the national minimum wage rules completely.
HMRC found out issues like:
- Unpaid working hours
- Incorrect deductions
- Misclassification of employees
Employee Complaints
HMRC will conduct surprise checks on your client if any of their disgruntled employees report their payroll issues directly to HMRC. Therefore, it is important for you to resolve any queries raised by the employees at the earliest and to the satisfaction of the employees.
Reports can be made anonymously through the pay and work rights complaints service, and Acas (0300 123 1100) also passes cases to HMRC.
High Staff Turnover
Frequent hiring and leaving of employees will raise the suspicion of HMRC that your client’s employees are unhappy and leaving their jobs, and raise the risk of a surprise check to verify the reasons.
Sector-Based Risk
Some of your clients will be under greater chances of frequent inspections by the HMRC, if they are from industries like:
- Hospitality
- Retail
- Construction
- Social care, cleaning and childcare — all heavily represented in Round 23
What Happens During an HMRC Wage Raid Payroll Check?
A check runs in five stages: officers arrive and state their purpose, they request payroll records, contracts, payslips and timesheets, they interview workers about hours and pay, they cross-check those answers against RTI and bank data, and they issue a written outcome. A notice of underpayment follows if arrears are found.
Keep your clients ready for HMRC wage raid payroll checks all the time, and make them aware of what to expect during an inspection.
Step 1: Surprise Visit
HMRC might send a notice or conduct a surprise visit to your client. They will introduce themselves and communicate with your client about the purpose of their visit.
Step 2: Request for Records for Reviewing
The HMRC officers will request certain documents for review. These documents are:
- Payroll records
- Employee contracts
- Payslips
- Timesheets
- Deduction schedules, salary sacrifice agreements and apprenticeship contracts — map these before a visit, not during one
Step 3: Discussions with Employees
Their employees will be interviewed directly by the HMRC to confirm:
- Hours worked
- Wages received
Step 4: Data Analysis and Crosschecking
HMRC will start reviewing the documents to check:
- Wage calculations
- Tax deductions
- Compliance with NMW rules
Step 5: Outcome
The outcome will be presented to your client with a written report outlining any discrepancies or violations.
Where arrears are due, HMRC issues a notice of underpayment setting out the arrears, the penalty and the deadline.
What Are the Penalties for Failing an HMRC Wage Raid Payroll Check?
The penalty is 200% of the underpayment for each worker, with a minimum of £100 per notice and a maximum of £20,000 per worker, plus full repayment of arrears recalculated at current NMW rates. The penalty halves if arrears and 50% of the penalty are paid within 14 calendar days. Employers owing more than £500 are publicly named.
Failing the HMRC wage raid payroll checks can have serious consequences for your clients and your practice. Those consequences are:
Financial Penalties
The penalty is 200% of the underpayment for each worker, with a minimum charge of £100 per notice and a maximum charge of £20,000 per worker, along with payment of backdated wages.
| Consequence | The rule |
| Arrears repayment | Full underpayment, recalculated at current NMW rates — a 2021 shortfall costs more in 2026 than it did then. |
| Financial penalty | 200% of the underpayment; minimum £100 per notice; maximum £20,000 per worker. |
| Prompt-payment discount | Penalty cut by 50% if all arrears are paid to all workers AND half the penalty is paid to HMRC within 14 calendar days of service. |
| Payment deadline | 28 calendar days from the date of service of the notice. |
| Appeal window | 28 calendar days to an employment tribunal. |
| Public naming | Where arrears exceed £500 — or £100 if a notice was issued in the previous six years. |
| Look-back period | Six years of payroll records. |

Public Naming
Recently, HMRC published 389 names of employers who were underpaying their employees, apart from recovering £12.6 million in penalties from them.
Reputational Damage
The penalties and public naming will not only damage the reputation of your client, but they will also create trust issues among their employees. Since your accounting practice is handling the payroll of your clients, it will badly reflect on your credibility and will break the trust of your clients.
What Rights Do Employers Have During an HMRC Visit?
Employers can ask officers for identification and a written explanation of the visit’s purpose, have their accountant present, keep a record of every question and document, and request reasonable time to produce records rather than handing them over on the spot.
Your clients are entitled to certain rights during the inspection by the HMRC. These rights are:
- Asking for identification and requesting an open explanation for the purpose of their visit.
- Keep your trusted accountant at the location.
- Keep a record of each question, document presented, and answer provided.
- Ask for a reasonable time to provide documents.
- Ask for findings in writing before agreeing to anything verbally.
How Can You Keep Clients HMRC-Ready? A Payroll Compliance Checklist
Run a six-point control: retain six years of records, audit quarterly against current NMW rates, test deductions and salary sacrifice against the hourly floor, track birthdays at 18, 20 and 21, verify apprentice year-one end dates, and confirm every RTI submission is on time.
“Prevention is better than cure”, it’s a proverb that is applicable not only to health but also to keep your clients protected from compliance trouble. The following steps can help avoid being on the HMRC minimum wage investigation list.
Keep Accurate Records
HMRC will be especially interested in the payroll records of your client; it’s your responsibility to have proper payroll records of the last six years, which include payslips, timesheets, and contracts.
From 6 April 2026, annual leave and holiday pay records join that six-year requirement.
Regularly Audit
Conduct frequent payroll audits of your clients to find out mistakes before the HMRC finds out.
Sample workers at the statutory floor rather than the average — the exposure sits with the lowest-paid handful, which is where HMRC starts.
Use Good Payroll Software
It’s even more important to get the best payroll software that is compliant with the latest MTD requirements so that no non-compliance occurs, and pay levels are adjusted automatically.
Keep Up With Wage Laws
In April 2026, the National Minimum Wage and National Living Wage will increase, giving a pay rise to around 2.7 million workers across the UK, including apprentices. If the rate update is delayed, then your client will face fines, and you will lose your credibility.
Teach Your Clients HR and Management Staff
Everyone who deals with payments or timesheets should know about wage laws, deductions, and how to stay compliant.
How Outsourced Payroll Reduces Your Risk from HMRC Wage Raid Payroll Checks
Outsourcing moves NMW checking from manual review into a standardised process applied identically across every client, with rate tables, deduction tests and birthday tracking built in. For a practice, that turns a portfolio-wide systematic risk into a controlled one.
These days, many small accounting practices are finding the compliance associated with payroll very time-consuming and complex, increasing the chances of errors and non-compliance. To play it safe and to keep their clients compliant, many are resorting to payroll outsourcing services to manage the risk.
Here’s where Equallto comes into the picture: you will get:
- Accurate payroll processing
- Compliance with HMRC regulations
- Support for RTI submissions
- Structured payroll workflows
- Reduced risk of errors

People Also Ask
Can HMRC arrive without notice for a payroll check?
Yes. HMRC has the legal authority to conduct unannounced payroll compliance visits, particularly for businesses in high-risk sectors, companies with a history of late RTI submissions, or cases where employee complaints have been received. Many checks begin with a letter or phone call and escalate to a site visit if records look inconsistent.
What Is an HMRC Wage Raid Payroll Check?
An HMRC wage raid payroll check is a compliance inspection, sometimes unannounced, where HMRC officers visit a business to verify that employees are paid at least the National Minimum Wage, that PAYE is deducted correctly, and that payroll is reported accurately through Real Time Information. “Wage raid” is media shorthand, not an HMRC term.
How far back can HMRC investigate payroll?
HMRC can enforce arrears across six years of payroll records. Arrears are recalculated at current NMW rates rather than the rates in force at the time, so a shortfall from 2021 costs more to settle in 2026 than it did originally. Where deliberate fraud is suspected, the window can extend further.
What is the HMRC minimum wage investigation?
A national minimum wage investigation can begin through a worker complaint or through targeted enforcement. HMRC’s aim is to confirm every worker at the business received at least the statutory rate for every pay reference period. Officers review pay records, contracts and working-time data, then issue a written outcome and, where arrears exist, a notice of underpayment.
What will the new minimum wage be in 2026 in the UK?
Come April 2026, the national minimum wage rate will increase to £12.71 for age 21 and above and £8.00 for apprentices.
What are the current NMW rates for 2026?
From 1 April 2026: National Living Wage (21+) = £12.71/hour. Workers aged 18–20 = £10.00/hour. Workers aged 16–17 = £7.55/hour. Apprentices = £7.55/hour. Any employer still paying at 2025 rates is already non-compliant.
What penalties apply for failing an HMRC wage raid payroll check?
Failing a wage raid payroll check carries a penalty of 200% of the underpayment per worker (minimum £100, maximum £20,000 per worker), plus full backdated wage repayment at current rates. Where arrears exceed £500, HMRC also publicly names the employer.
Conclusion
In 2026, HMRC wage raid payroll checks are more frequent, more data-driven, and wider in scope than at any previous point — particularly with the launch of the Fair Work Agency extending inspections into holiday pay and sick pay. For you and your clients, payroll can no longer be treated as a routine administrative task. It is a compliance responsibility with real financial and reputational consequences.
The good news?
With the right systems, processes, and support, you can stay ahead. By combining:
- Accurate six-year record-keeping across payroll, pensions, and holiday pay
- Quarterly internal audits using the current April 2026 NMW rates
- Compliant RTI submissions with no late filings or discrepancies
- Staff trained on what HMRC looks for in a wage raid payroll check
- Deduction and salary sacrifice testing against the £12.71 floor
You can reduce risk significantly.
