HMRC investigations can be triggered by several factors. Common triggers include discrepancies or errors in tax returns, late or incomplete filings, and unusual patterns of claims or deductions. Significant fluctuations in income, frequent losses, or large, unusual expenses can also raise red flags. Additionally, HMRC may initiate investigations based on information received from third parties, random selection, or industry-specific compliance projects. Businesses operating in high-risk sectors or those with a history of non-compliance are more likely to be scrutinised. Understanding these triggers can help businesses maintain proper records and ensure compliance to avoid investigations.
An investigation may also be triggered by insolvency proceedings.
