HMRC VAT Nudge Letters: What to Do If One Lands on Your Doormat
If you run a VAT-registered business and have not heard from HMRC about VAT in the last five years, there is a reasonable chance a letter is already on its way. HMRC has launched a new wave of so-called "nudge letters" targeting VAT-registered businesses that have not been subject to a compliance check in five or more years — and the message is blunt: 50% of recipients will be selected for a full VAT compliance check within the next two years. This is not routine correspondence. It is an early warning that HMRC is turning its attention to your records — and ignoring it could prove costly.
- HMRC is actively sending "nudge letters" to VAT-registered businesses not reviewed in the last five years.
- Exactly 50% of businesses receiving one of these letters will be targeted for a full VAT compliance check.
- HMRC's scrutiny centres on five core areas: records, private use adjustments, partial exemption, international supplies, and VAT classification.
- Businesses that take "reasonable care" and make voluntary disclosures face lower penalties.
- Acting proactively — ideally with your accountant — before HMRC contacts you can save time, stress, and money.
Why Is HMRC Doing This Now?
The driving force behind this new compliance push is HMRC's determination to close the "VAT gap" — the difference between what it expects to collect and what businesses actually pay. Although the gap has narrowed over recent years, it remains substantial enough to keep VAT high on HMRC's priority list for 2026/27.
Three additional factors have made VAT more complex for many businesses: the UK's exit from the EU, temporary reduced VAT rates in certain sectors, and ongoing legislative changes. Even well-run businesses can drift out of compliance as their processes fail to keep pace with these shifts. HMRC is now actively targeting those gaps.
A nudge letter (also called a "one-to-many" letter) is a formal communication from HMRC indicating your business may be selected for a VAT compliance check. It is not an accusation of wrongdoing — but it does signal that HMRC has identified your business as one that warrants closer scrutiny. Receiving one does not mean you have made errors; it means HMRC wants to check. How you respond matters.
What Will HMRC Look At?
Under the current initiative, HMRC's focus is broad rather than industry-specific. A VAT compliance check typically examines five key areas:
- VAT records, reconciliations and controls — Are your records complete, accurate, and consistent with your financial accounts? Weak controls raise a red flag, even where any errors are entirely unintentional.
- Private or non-business use adjustments — If business assets or services are used privately, this must be correctly accounted for. Calculations need to be clearly evidenced.
- Partial exemption and input tax recovery — Businesses making both taxable and exempt supplies must apportion input VAT correctly. This is one of the most common areas where errors occur.
- International supplies — Post-Brexit rules have added layers of complexity around overseas services, place of supply, and import/export documentation.
- VAT liability and classification — Are your supplies correctly classified as standard-rated, reduced-rated, zero-rated, or exempt? Misclassification is another frequent finding.
Certain events significantly increase your VAT risk and should prompt an immediate internal review:
- Corporate transactions — sales, acquisitions, or business restructures
- Changes to accounting software or internal systems
- Expansion into new markets or countries
- Land and property transactions
- Any period where your VAT treatment has not been reviewed against current legislation
VAT is a transactional tax — getting it right at the time of each event is critical, and errors discovered later are harder to correct without penalty.
What Should You Do If You Receive a Nudge Letter?
The worst thing you can do is ignore it. HMRC is clear that acting proactively — before an inspector arrives — puts you in a significantly stronger position. Here is what to do:
- Do not delay — Contact your accountant as soon as the letter arrives. Early action gives you time to manage the situation on your terms.
- Commission a VAT health check — A proactive review of your VAT records, processes, and past returns will identify any areas of concern before HMRC does.
- Consider voluntary disclosure — If errors are found during your review, disclosing them voluntarily to HMRC before an inspection typically results in significantly lower penalties.
- Document your processes — Create or update a tax risk register. Showing HMRC you take compliance seriously is one of the most effective ways to demonstrate "reasonable care."
- Review your MTD compliance — If you are VAT-registered, you should already be using MTD-compatible software. Any gaps here will be scrutinised.
HMRC's own guidance makes clear that penalties are less likely — or reduced — where a business has taken "reasonable care." This means keeping accurate records, reviewing uncertain areas, and seeking professional advice when needed. Reasonable care is not just a legal concept; it is a practical defence.
