About Us
At Tax Investigation Helpline, we understand how stressful it can be when HMRC launches an investigation or when bad accountancy advice leaves you exposed to unnecessary risk. Our mission is simple: to defend individuals and businesses against HMRC, correct mistakes caused by poor guidance, and hold negligent accountants accountable for the damage they cause.
Who We Are
We are a team of tax investigation specialists with extensive experience handling HMRC enquiries across every area of tax. From corporation tax and VAT to PAYE, IR35, CIS, and inheritance tax, we know how HMRC works — and more importantly, how to protect our clients from unfair penalties and financial losses.
Unlike general accountants, we are not here to simply crunch numbers. We are here to fight for you when things go wrong. Whether HMRC has raised questions about your tax affairs or your accountant has given you poor advice, we step in to put things right and defend your position.

We provide clear, expert support in three key areas:
1. HMRC Investigations
Representation in all types of tax enquiries, from routine compliance checks to complex COP8 and COP9 cases. - Protection against unfair penalties and aggressive HMRC tactics. - Negotiation to reduce liabilities and achieve fair settlements.
2. Accountancy Negligence
Support for clients let down by bad advice or poor service from their accountants. - Identifying errors in VAT, PAYE, IR35, CIS, director’s loans, inheritance tax, and more. - Helping clients hold negligent accountants accountable.
3. Corrective Action & Future Protection
Reviewing your tax position and correcting errors in past filings. - Ensuring compliance with current legislation. - Giving you the right advice so you can move forward with confidence.

Our Mission
We believe no individual or business should face HMRC investigations or accountancy negligence alone. Our mission is to stand with you, defend your interests, and ensure you achieve the best possible outcome.
