What are tax investigations?

Tax Accountants in York

A tax investigation (also known as a tax compliance check) is the formal examination of an individual’s or business’s financial records by tax authorities – in the UK, this would be HMRC.

During an investigation, HMRC will review income, expenses, deductions, and any other relevant financial transactions to verify the taxpayer has accurately reported and paid the correct amount of tax.

These tax investigations can take up to 12 months, with longer investigations going up to five years or more if they suspect deliberate tax avoidance.

Why are you being investigated?

Anyone can be investigated for tax compliance. It’s not just celebrities and millionaires – HMRC opens investigations every day on individuals and businesses of all sizes and earning levels.

Tax investigations can be triggered for a variety of reasons, including:

  • Discrepancies or errors in your latest tax return
  • Consistently filing late tax returns or paying tax bills late
  • History of non-compliance or previous penalties
  • High-expense claims that don’t match the industry norm
  • Someone reports you for potential tax avoidance or fraud
  • Random selection
  • …and more

How far back does a tax investigation go?

Once an investigation is opened, HMRC will start by reviewing your most recent tax return to check whether there are any errors or discrepancies. If everything looks good, they might close the investigation there.

However, if there are any innocent mistakes, they might check your financial records for the last four years. For negligent or more serious mistakes, they could go back six years. If it looks like someone tried to dodge taxes on purpose, HMRC can investigate up to 20 years of financial history.
