Self-Assessment Investigations
Completing a self-assessment tax return can be complicated, especially if you have multiple income sources, complex expenses, or rely on third-party accountants. Unfortunately, even small mistakes can trigger an HMRC investigation.
If you’ve received a letter about your self-assessment return, it’s natural to feel anxious — but with the right support, you can protect yourself and resolve matters effectively. At Tax Investigation Helpline, we specialise in helping individuals under HMRC investigation.
Why HMRC Investigates Self
Assessment Returns Every year, HMRC reviews thousands of self-assessment returns to identify underpayments and errors. Common triggers for investigation include:
- Income reported that doesn’t match HMRC’s records (e.g., PAYE, bank interest, dividends).
- Large or unusual expense claims.
- Late or missing tax returns.
- Discrepancies between your self-assessment and information from employers, banks, or other sources.
- Random selection — sometimes HMRC checks returns even where no red flags appear.
What’s at Stake in a Self-Assessment Investigation HMRC has wide-ranging powers, and the outcome of an investigation can be serious:
- Re-assessed tax bills, often covering several years.
- Penalties and interest charges that significantly increase the amount owed.
- Stress and disruption, particularly if HMRC asks for extensive documentation.
- In rare but serious cases, criminal investigation for deliberate tax evasion.
Even if mistakes were genuine, HMRC can impose penalties unless you can prove you took reasonable care.
