What is a

tax investigation?

A tax investigation is an in-depth investigation processed by a tax authority to recover tax undercharged in previous years of assessment. It is often carried out when a taxpayer is suspected of tax evasion, or just by random sampling.


There are many types of tax investigations. The primary services More Group can assist with include:

  • HMRC Investigation

  • Tax Fraud and Tax Evasion

  • Serious tax fraud investigation (Code of Practice 9 – CDF)

  • Tax avoidance investigation (Code of Practice 8)

  • Voluntary Tax Disclosure

  • Liechtenstein Disclosure Facility (LDF)

  • HMRC Compliance Check

  • Personal Tax Investigation

  • Company Tax Investigation

  • Offshore Investigation

  • Criminal Tax Investigation

  • VAT Investigation

  • Residence and Domicile Enquiry

  • Status Enquire

  • PAYE Investigation

  • Tax Tribunal

Can the authorities inspect anyone's tax affairs?

The tax authorities can inspect anyone.


You will be informed of a tax audit or tax investigation when the tax authority contacts you. For a tax audit, a tax officer will generally want to visit you and check your tax records. As standard, a tax investigation will start with a formal letter requesting information.

The letter will state whether the tax authority is investigating a particular aspect of your taxes or carrying out a full tax investigation. Your accountant will also be able to determine why there is a tax investigation (e.g. whether they suspect tax fraud).

Generally, a tax enquiry starts within 12 months of the due date for the tax return it relates to or if you missed the due date, 12 months after you filed the return.
