A tax investigation is a thorough tax review conducted by the tax authorities, such as HMRC, to ensure that a taxpayer is paying the correct amount of tax. These investigations can be random or triggered by discrepancies in a taxpayer’s financial records. The aim is to ensure the correct amount of tax is being paid by an individual or business, and that there has been no evasion or fraud – in the case of evasion, HMRC aim is to recover any unpaid taxes.
The process usually begins with a formal notification from the tax authority. The taxpayer may be required to provide detailed financial records, including bank statements, invoices, and receipts. If any discrepancies are found, further action may be taken, which could include penalties or legal proceedings.
HMRC may choose to investigate you for several reasons. For example:
