Vexo Accounting provides tax investigation cover, HMRC investigation insurance and tax enquiry fee protection to sole traders, landlords and limited companies right across the UK. If HMRC opens an enquiry into your tax return, our cover pays the professional fees involved, so that letter never turns into a large bill.
A tax enquiry can land on your desk even when you have done nothing wrong. HM Revenue and Customs, better known as HMRC, runs a completely random investigation programme, and both can cost you time and money.




Get tax investigation cover from Vexo Accounting to help protect against professional fees if HMRC opens an enquiry, with expert support and representation when you need it.
HMRC does not need a strong reason to investigate a tax return; sometimes it is just random selection. If you are worried about an HMRC tax investigation, get cover in place early, because something on your return can look unusual even when nothing is wrong. A compliance check can cover income tax, corporation tax, VAT, PAYE, National Insurance and capital gains tax, and any part of your return can be subject to review.
There are two broad types of enquiry. An aspect enquiry looks at one part of your return, such as a single expense claim or your rental income. A full enquiry is a more time-consuming review of your business finances, and it can become an in-depth enquiry once HMRC asks for several years of records.
Most cases start as a routine enquiry, and HMRC works through your figures by letter or phone. A smaller number escalate into a serious tax investigation under Code of Practice 9, where HMRC suspects deliberate wrongdoing, and a company should investigate its own records before replying. Tax specialists from day one change how the case is handled.
Large business enquiries settled last year took an average of 16 months to close, and around half of the UK's biggest businesses are under some form of check.

We spot opportunities and challenges early, helping you stay ahead.
Secure, real-time access, anywhere you need it.
We value your time and get answers when you need them.
Plain English with no surprises. Fixed fees for total clarity.

An HMRC tax enquiry rarely arrives with much warning, which is why cover needs to be in place beforehand. An aspect enquiry into one line of your tax return can cost £1,000 to £3,000 in fees to defend, even where HMRC finds nothing wrong, and a full enquiry across your business finances can run into five figures.
Defending even a simple enquiry without cover can cost thousands. That is the financial burden our tax investigation insurance removes, and there's no extra cost if HMRC's questions widen part way through; the same policy keeps you covered. Our tax defence team keeps defence costs predictable and continues to protect and investigate on your behalf until the case closes, which is what providing peace of mind really means.
HMRC brings in tens of billions a year through its compliance work, generating more than £50 billion in compliance yield and adding over 1,600 new compliance officers. Small businesses alone accounted for close to £12 billion of that yield, showing ordinary businesses get drawn in too.
The wider UK tax gap stood at £59.2 billion in the most recent year, around 6.4% of total tax due. That gap is why HMRC keeps investing in more staff and checks, and why every taxpayer carries some risk of a check.



An HMRC letter can arrive at any time, and once an enquiry has started, it's too late to add cover.
