Tax Investigation Service

HMRC could strike at any time. Don’t get burnt.

What is a Tax Investigation?

  • Many tax investigations occur randomly. However, unusual fluctuations, undisclosed accounts, and irregular spending can also trigger an enquiry into individuals and companies.
  • HMRC has the authority to inspect business documents and assets at your premises, request additional documents and information, conduct unannounced inspections, and investigate matters going back up to six years.
  • These investigations can be disruptive, intrusive, and costly. When HMRC investigates, the process can extend for a year or more, leading to mounting expenses and increased stress levels.

Case Studies

Incorrect Information

HMRC opened an enquiry into an individual suggesting a client had not declared all of their income on their tax return. HMRC then refused to disclose to the client what information they held.

The enquiry lasted for over three years and cost over £15,000 to deal with in accountancy fees alone.

It turned out that HMRC’s information was incorrect and that no tax penalties or interest were due. However the accountant’s fees were still settled under the Tax Investigation Service.

Cross Tax Enquiry

HMRC launched a “Cross Tax Enquiry” into a manufacturing business that included a full review of the entire corporation tax return and four years of PAYE and VAT records.

From the outset it became clear that HMRC were unsure exactly what they were looking for and were undergoing a fishing expedition.

The questioning became increasingly onerous and seemingly endless. After one meeting alone, dozens of questions followed. Despite the best efforts of the advisor, the enquiry dragged on for over two years, resulting in only small adjustments. Over £20,000 of fees were settled under the Tax Investigation Service.

Did you know?

Last year HMRC collected £48 billion from tax investigations and enquiries. They also revealed that in the year to 2024, it brought in a record total of £875.9 billion in taxes, £32.5 billion more than the previous year.

It could happen to you.

Every year, HMRC carries out enquiries into the tax affairs of an increasing number of individuals and businesses in the UK. Many people find an HMRC enquiry disruptive, intrusive, stressful and ultimately expensive.

There does not need to be a reason for HMRC to check your tax affairs. If you submit a tax return you can be selected at random, even if you have done nothing wrong.

There has been a surge in compliance cases opened by HMRC as it ramps up tax investigations work. 333,000 checks had been opened during 2024/25 – up 7% from the prior year. A tax investigation can cost you thousands of pounds in accountancy fees and can often drag on for years. The average cost of an investigation is £3,800 in accountancy fees.

Nothing to hide?

Many tax enquiries are conducted at random. Unfortunately even innocent taxpayers get caught up in the process and are under threat of investigation. Whether or not there is an issue with your tax affairs, an investigation is a time-consuming process that can rack up substantial accountancy fees.

We have taken out an insurance policy in our own name that is backed by Bespoke Fee Protection, one of the UK’s leading providers. Our policy enables us to provide you with expert advice and peace of mind knowing we will work on your case to resolve the situation up to our service limits.
