Under HMRC Investigation or Let Down by Your Accountant? Here’s What to Do Next.
If you’ve recently received a letter from HMRC or found yourself facing questions about your tax returns, it’s natural to feel anxious.
Every year, thousands of individuals and businesses across the UK face HMRC tax investigations, often because of simple errors, poor advice, or their accountant’s negligence.
At Tax Investigation Helpline, we specialise in helping taxpayers across the UK resolve HMRC investigations, challenge unfair penalties, and recover financial losses caused by accountants’ mistakes.
Here’s how we can help you protect your finances and reputation.
Why HMRC Might Be Investigating You.
HMRC investigates individuals and companies to ensure everyone pays the correct amount of tax. Common reasons include:
- Discrepancies or omissions in tax returns
- Late or missing submissions
- Unusual claims or expenses
- Third-party data, such as bank information
- Or simply random selection
Even if you use a qualified accountant, you remain legally responsible for your tax returns. If HMRC believes there’s an issue, they may start a compliance check or full investigation, which can lead to penalties unless handled correctly.
Types of HMRC Investigations.
HMRC investigations generally fall into three categories:
- Full Enquiry – A deep dive into your entire tax position, including business accounts, personal returns, and bank statements.
- Aspect Enquiry – Focused on a specific part of your tax return, such as expenses or income.
- Random Check – Selected at random, regardless of your compliance record.
These investigations can be stressful, but expert advice makes a huge difference. Our tax investigation specialists deal directly with HMRC on your behalf to achieve the best possible outcome.
When Your Accountant Is at Fault.
Many investigations start because an accountant has made a mistake. Clients often contact us after discovering that their accountant:
- Missed submission deadlines
- Filed incorrect returns
- Claimed ineligible expenses
- Ignored HMRC correspondence
- Provided inaccurate advice
If these errors have caused financial loss or triggered an HMRC enquiry, you may be entitled to compensation for professional negligence.
At Tax Investigation Helpline, we work with trusted legal experts to recover losses from negligent accountants while managing your HMRC case.
