'We Are Coming For You': HMRC's 30,000 High Street Raids — What Your Shop Needs to Do Now

HMRC has launched a programme of 30,000 unannounced high street visits in 2026/27. The campaign is already live — London souvenir shops were raided this week. Treasury minister James Murray told reporters publicly: "We are coming for you." That is not a warning. It is an announcement. If you run a retail shop, café, bar, barber, vape shop, or convenience store in the UK, you need to read this now.

This guide covers exactly what HMRC inspectors check during a raid, what the penalties look like, and the five concrete steps every high street business should take before an inspector walks through the door.

What Is Actually Happening

HMRC's 2026/27 high street campaign is the largest coordinated retail enforcement operation since VAT inspections were digitalised. The headline number — 30,000 visits — represents a step change from the previous year's programme. The Treasury has deployed 350 new criminal investigators specifically for this campaign, on top of existing compliance teams.

The campaign began with London's souvenir and tourist trade — a sector HMRC has long suspected of widespread cash handling irregularities — but the visit programme covers all high street business types. Retail, hospitality, personal care (barbers, salons, nail bars), vape and specialist retail, and convenience stores are all explicitly in scope.

The visits are unannounced. Inspectors arrive during trading hours, badge in, and begin their review on-site. There is no advance warning. No courtesy call. No chance to tidy the filing cabinet. This is by design.

"We are coming for you." — Treasury Minister James Murray, 2026

For most shop owners, the immediate panic is the till. But HMRC's sweep is considerably wider than cash fraud.

What HMRC Raids Actually Check

An HMRC high street visit covers five key compliance areas. You should treat each as a separate risk:

1. Electronic Sales Suppression (ESS)

HMRC inspectors can perform a full till download on-site. They are specifically looking for ESS — the use of software or hardware to suppress, delete, or manipulate sales records to reduce VAT and income tax liability. ESS tools are increasingly sophisticated, ranging from standalone "phantom mode" devices to cloud-based services sold to small retailers. HMRC's digital forensics capability has outpaced ESS suppliers. If your POS has been modified, they will find it.

2. National Living Wage and National Minimum Wage

Inspectors check payroll records against hours worked. The current rates (since April 2026) are:

• 21 and over (National Living Wage): £12.71 per hour
• 18–20: £10.85 per hour
• 16–17 and apprentices: £8.00 per hour

Any shortfall — even by pence — triggers an enforcement notice. HMRC will calculate arrears across the full period of underpayment and apply a 200% penalty on top.

3. Right-to-Work Records

Every employee requires documented right-to-work verification. Inspectors check the records are in place, current, and properly stored. The civil penalty for employing someone without a valid right to work is up to £45,000 per worker — raised from £20,000 in January 2024. That is per worker, per offence. Three undocumented staff and you are looking at £135,000 before legal costs.

4. Counterfeit and Grey-Market Goods

Inspectors check stock records against purchase invoices. If you sell electronics, clothing, branded goods, or accessories, they are looking for goods purchased through channels that cannot demonstrate legitimate origin. Seized goods are not returned. Criminal prosecution for persistent or large-scale counterfeiting is a real outcome.

5. Cash-Handling Records

HMRC's visit teams include specialists trained to identify Z-report discrepancies, missing daily till readings, and patterns in cash deposits that do not match declared turnover. If your cash records are incomplete or inconsistent, expect a formal investigation to follow.

The Penalties Are Severe

These are confirmed outcomes from the current campaign, not hypotheticals:

• £40,000–£45,000 civil penalty per illegal worker (single visit finding)
• NMW arrears plus 200% penalty on all underpaid wages — going back up to 6 years
• Criminal prosecution for ESS — up to 7 years imprisonment, unlimited fine
• Goods seized on-site with no right of return for counterfeit stock
• Public naming and shaming — HMRC publishes the names of NMW non-compliant employers quarterly
• Tax investigation triggered by any finding — cash records discrepancies escalate to full accounts investigation

There is no penalty cap for deliberate non-compliance. The £40,000 worker figure quoted above was a single London raid in the current campaign. Multiply that across a business employing a handful of undocumented workers and the financial consequences are existential.

5 Actions to Take Right Now

You do not get advance warning of an HMRC visit. But you can be ready before they arrive. Here are the five actions every high street business should complete this week:

Action 1: Confirm Your NLW Rates Are Correct

The rates increased on 1 April 2026. If you set up payroll last year and have not updated it, you may already be underpaying. The 21+ rate is now £12.71 per hour. Check your payroll software, your pay slips, and your employment contracts. If you pay a flat hourly rate across all staff regardless of age, audit it now. Run a quick check: multiply each worker's contracted hours by £12.71 (if they are 21 or over) and confirm your payroll output matches.

Action 2: Audit Your POS System for ESS Compliance

If you have recently had anyone work on your till system, installed a third-party "efficiency" add-on, or purchased hardware from an unfamiliar supplier, get your system audited by your POS provider. HMRC's forensics team can identify ESS modifications that the business owner was not even aware had been installed — the liability is yours regardless. Legitimate POS systems from recognised suppliers (EPOS Now, Lightspeed, Square, etc.) keep unalterable audit logs by design. If yours does not, that is a serious flag.

Action 3: Locate and Review Right-to-Work Records

For every current employee, you need a copy of their right-to-work verification — passport, visa, or share code check — on file. It should be dated on or before their first day of work. If your records are in a drawer, a folder, or a personal email inbox, consolidate them now. Digital copies are acceptable. The key test is: if an inspector asked you to produce right-to-work evidence for every member of staff this morning, could you do it in five minutes?

Action 4: Check Your Stock Records and Supplier Invoices

For any goods-selling business, ensure you can trace every product line back to a documented supplier. If you purchase through marketplaces, wholesalers, or cash-and-carry, keep purchase records. For branded goods especially — electronics, clothing, accessories, fragrances — a clean audit trail from supplier to shelf is your protection against counterfeit allegations.

Action 5: Set Up Alerts for NMW Rate Changes and Enforcement Updates

HMRC's enforcement priorities shift. The current retail campaign is explicitly flagged as a response to underpayment patterns in the sector. When the next rate change comes — and there is always another rate change — you need to know immediately, not three months later. ComplianceAlert monitors NMW/NLW rates and sends you a plain-English alert the moment anything changes. The Action Centre includes an NMW compliance checklist you can work through before any HMRC visit. It is free forever — no card required.

Electronic Sales Suppression: What It Is and Why HMRC Hates It

Electronic Sales Suppression (ESS) is the practice of using software or devices to reduce the sales figures recorded by a point-of-sale system — and therefore reduce the VAT and income tax due on those sales. A "phantom transaction" mode, for example, processes a real sale but routes it off the books. A "zapper" device deletes individual transactions after they are processed.

HMRC estimates ESS costs the Treasury over £100 million per year in lost tax revenue, concentrated in cash-heavy high street sectors: restaurants, takeaways, retail, personal services.

The Finance Act 2022 created specific ESS offences. Possessing, using, supplying, or designing ESS tools is now a criminal offence. The "I didn't know it was doing that" defence is very difficult to run — if the software is on your hardware, in your premises, and has been suppressing sales, you are responsible.

HMRC's on-site till download capability means they do not need to find a device. They can extract the till's forensic log, compare it against banking records and VAT returns, and identify discrepancies algorithmically. This is why the 30,000-visit programme is effective: the technology makes it fast.

National Living Wage: The Easiest Win for HMRC

NMW non-compliance is genuinely the easiest enforcement win for HMRC. The maths is simple: contracted hours multiplied by rate, compared to pay slips. A business that has not updated its payroll since before April 2026 is almost certainly underpaying. The current rate for workers aged 21 and over is £12.71 per hour.

The most common causes of NMW non-compliance in retail:

• Failure to update payroll after the April 2026 rate change — still paying £12.21 (the 2025 rate)
• Deductions reducing effective pay below NMW — uniform costs, till discrepancies, training charges
• Unpaid pre-shift and post-shift time — if staff are required to arrive 10 minutes early or stay to close, that time counts
• Misclassification of workers as self-employed to avoid payroll obligations
• Accommodation offset calculation errors — if you provide accommodation, the offset is £11.10 per day

HMRC names non-compliant employers publicly. A business appearing on the quarterly HMRC NMW shame list does not just face a fine — it faces reputational damage that can be harder to recover from than the financial penalty.

Right-to-Work Checks: The £40,000 Trap

The civil penalty for employing a person who does not have the right to work in the UK rose to £45,000 per worker in January 2024. This is a civil penalty — it does not require a criminal prosecution. It applies if you did not complete a right-to-work check before the employee started work, or if your check was not conducted correctly.

A correct right-to-work check requires:

• Obtaining original documents (or a valid share code check for overseas nationals)
• Checking the documents in the presence of the holder
• Making a clear copy and recording the date of the check
• For time-limited permissions: scheduling a follow-up check before the permission expires

Conducting a check is not optional and a statutory defence is only available if the check was done correctly. "We asked them and they said they had the right to work" is not a statutory defence. The document check is.

Frequently Asked Questions

Can HMRC visit my shop without warning?

Yes. HMRC has the power to make unannounced visits to business premises under powers contained in the Finance Act 2008 (Schedule 36). They do not require a warrant for routine compliance visits. If they have specific suspicions of fraud, they can obtain a warrant and may involve police. The current high street campaign uses unannounced visits as standard practice.

What happens if HMRC finds a problem during a visit?

Minor procedural issues (e.g., records not immediately to hand) typically result in a formal notice requiring you to produce records within a set period. More serious findings — underpaid NMW, right-to-work failures, ESS evidence — trigger a formal investigation. Penalties can be issued on the spot for right-to-work failures. ESS findings are typically referred to a specialist team and can result in criminal prosecution.

I paid the wrong NMW rate by mistake — what should I do?

Voluntarily disclose to HMRC before they find it. The penalty regime offers reduced penalties (down to 0% in some cases) for unprompted voluntary disclosure compared to penalties applied after HMRC discovers the shortfall. Calculate the arrears, pay your staff immediately, and contact HMRC's NMW team. Do not wait for them to find you.

My POS supplier installed an update I didn't understand — could it be ESS?

Contact your POS supplier immediately and ask them to confirm in writing that their system does not contain any ESS functionality and is fully HMRC-compliant. Reputable suppliers will provide this confirmation as standard. If they cannot or will not provide it, consider changing your POS system and notifying HMRC proactively — the voluntary disclosure route is significantly better than being found with ESS in situ.

Are barbers, nail bars, and salons affected?

Yes. Personal care businesses — barbers, hairdressers, nail bars, beauty salons, tattoo studios — are explicitly within scope of the 2026/27 campaign. They are particularly targeted for cash handling irregularities and self-employment misclassification (stylists who are in practice employed but treated as self-employed).
