HMRC Investigations

Being the subject of a tax investigation by HM Revenue & Customs (HMRC) can be stressful, time-consuming, and disruptive

Being the subject of a tax investigation by HM Revenue & Customs (HMRC) can be stressful, time-consuming, and disruptive. Whether it’s a routine compliance check or a full enquiry into your tax affairs, knowing that you are under scrutiny can cause significant worry and uncertainty.

At Four Fifty Partnership, we have extensive experience in dealing with HMRC investigations. Our expert team will step in to manage the process on your behalf, liaising directly with HMRC, preparing the necessary documentation, and guiding you through every stage of the enquiry. With our support, you can be confident that your case is handled efficiently and professionally, while minimising disruption to your personal or business life.

We provide tailored advice and hands-on support in all types of HMRC enquiries, including:

  • Personal tax investigations – covering self-assessment, income tax, capital gains tax, and inheritance tax
  • Business tax investigations – including corporation tax, VAT, PAYE, and CIS compliance checks
  • Full enquiries and aspect enquiries – from broad reviews of your tax affairs to checks on specific areas
  • Record reviews – assisting with requests for books, records, and supporting documents
  • Negotiations with HMRC – managing communications to achieve the best possible outcome
  • Mitigating penalties – advising on how to reduce or avoid fines and interest charges

Fee Protection Service

To give our clients even greater peace of mind, we offer a fee protection service. For a small annual fee, you are protected against the professional costs of dealing with an HMRC investigation. This service is backed by an insurance policy held by the firm, ensuring that if you are selected for an enquiry, our fees for handling the process are covered.

As part of this service, you will also have access to a business, employment and legal helpline, giving you expert advice on a wide range of legal matters whenever you need it.

Dealing with HMRC without expert support can be daunting. We not only remove the stress of handling the investigation yourself but also use our knowledge of tax law and procedure to ensure your rights are protected and your liabilities are minimised.

Our approach is professional, discreet, and proactive. We explain the process clearly, keep you fully informed, and work tirelessly to resolve matters as quickly and smoothly as possible.

If you are facing an HMRC investigation, don’t panic—let us do the hard work for you. Contact our team today to discuss your situation and to find out more about the protection and peace of mind offered by our fee protection service.
