Tax Investigations

Tax Investigations and Disclosures

To those without a tax background, a tax investigation by HMRC can be extremely stressful and potentially have an impact on your business and personal life. STS (Europe) Limited aim to relieve part of that stress by assisting clients who are the subject of direct and indirect tax investigations by HMRC.

Investigations range from enquiries into an individual’s tax return for a single year, to detailed reviews of complex financial affairs of large corporations, including UK and overseas entities stretching back several years.

Our team’s knowledge of HMRC’s procedures and tactics is unrivalled, using a network of former senior HMRC inspectors with over 220 years of combined experience. This enables us to be in the best position to advise clients on the various approaches and strategies they have available to them. Once all the relevant facts have been determined, we will interact and co-operate with HMRC on your behalf, taking away the stress of dealing with the inspectors.

Our role, in all investigation cases, is to establish the facts and determine the tax consequences of those facts. We will then negotiate the best position for the client with HMRC, whilst resolving the problem on a civil basis in a time efficient manner.

We advise clients on all types of investigations and disclosures:


  • Code of Practice 8,
  • Code of Practice 9,
  • Worldwide Disclosure Facility,
  • Personal tax returns,
  • Corporation tax returns,
  • VAT returns,
  • Offshore Trusts and Companies,
  • Advice on legal action against professional advisors.

We also act in cases where HMRC have decided to prosecute instead of dealing with a case on a civil basis. Again, we work closely with the client and the legal advisors, aiming to achieve the best possible position for the client.


  • Detailed forensic analysis of evidence to establish tax liabilities,
  • Provision of technical tax support for legal defence teams,
  • Provision of witness statements,
  • Computational support for legal defence teams.

Depending on the requirements of the case we can obtain bespoke advice from a number of leading Tax Counsel.
