Tax Investigations Service - Are you protected?

Tax investigations are a costly business, and order to ensure that our clients are protected against the expenses of an investigation, we offer the opportunity to enrol with our HMRC Investigation Service which is fully backed by an Insurance Policy, by Markel Tax.

If you are subject to an enquiry, as a member of our HMRC Investigation Service you will have one of our expert tax consultants defend and negotiate your position with HMRC, protecting you from any costly fees, free of charge.

Having the appropriate service protection removes any stress and will save you a great deal of time and resource that could save you thousands of pounds.

Protect Yourself with Our Tax Investigations Service

Here are five reasons why we feel it is important to take out our HMRC Investigation Service.

  • Tax investigations can happen to anyone, whether you are an individual or in business.
  • HMRC is working hard to collect more revenue than ever before. Last year it generated £30.4 billion from compliance activity and it plans to increase this figure significantly over the next 12 months. This means that the chances of being selected for an enquiry are on the rise.
  • HMRC is becoming more sophisticated in its approach to recovering tax with the details held within its systems. This enables HMRC to be increasingly targeted in its selection of those it chooses for investigation.
  • Don’t underestimate the impact on you or your business of the stress and anxiety caused by being selected for an enquiry.
  • Our HMRC Investigation Service ensures that you have an experienced professional on your side when you need them at no additional cost.
