Offering Comprehensive Help with HMRC Tax Investigations
HMRC investigations come in various forms, each with different procedures and potential outcomes. Understanding what you’re facing is the first step to managing the situation effectively.

Why You Need Specialist Tax Dispute Accountants in the UK
HMRC investigations are serious matters that can result in significant financial consequences, including additional tax, interest and penalties. The way you handle the initial stages often determines the final outcome, making professional representation crucial from the outset.
Our team understands HMRC’s procedures, your rights as a taxpayer, and how to present your case in the most favourable light. We know when to cooperate, when to challenge and how to negotiate effectively to achieve the best possible outcome. More importantly, we handle all communications with HMRC, allowing you to focus on your business or personal matters while we manage the investigation.

Our Tax Audit Services in the UK
Every investigation is unique, requiring a tailored approach based on the specific circumstances and issues involved. We begin by thoroughly understanding your situation, then develop a strategic response that protects your interests while maintaining a professional relationship with HMRC.
Initial Assessment and Strategy
We start by reviewing all HMRC correspondence and your tax position to understand the scope of the enquiry and identify potential issues. This allows us to develop a comprehensive strategy and prepare you for what to expect throughout the process.
Professional Communication
All correspondence with HMRC goes through us, ensuring consistency in responses and protecting you from potentially damaging direct communication. We handle all meetings, phone calls and written exchanges professionally and strategically.
Technical Defense
Where appropriate, we robustly defend your position using detailed technical arguments, case law and precedent. We’re not afraid to challenge HMRC’s position when we believe they’re wrong, but we do so in a way that maintains constructive dialogue.
Negotiated Resolution
Most investigations are resolved through negotiation rather than formal appeals. We use our experience and relationship with HMRC to negotiate settlements that minimise additional tax, interest and penalties while bringing the matter to a swift conclusion.

Protecting Your Interests with HMRC Compliance Checks Suppo
Our primary goal is to achieve the best possible outcome for you while minimising the disruption to your life or business. This means not just focusing on the immediate investigation, but also considering the long-term implications and ensuring your ongoing compliance.
We keep you informed throughout the process, explaining what’s happening at each stage and involving you in key decisions. You’ll never be surprised by developments, and you’ll always understand your options and the likely outcomes.

Frequently Asked Questions.
Here is a list of the most frequently asked questions from our clients.
Q.
What are the potential outcomes of an HMRC investigation?
A.
Outcomes can range from no change to your tax position, through to additional tax assessments, interest charges and penalties. In serious cases, HMRC may pursue criminal prosecution, though this is relatively rare and typically reserved for cases involving deliberate fraud or evasion.
Q.
How long do HMRC investigations typically take?
A.
The duration varies significantly depending on the complexity of the case and the issues involved, ranging from a few months for simple enquiries to several years for complex investigations. However, having professional representation often speeds up the process as we can provide information efficiently and negotiate resolutions more effectively.
Q.
What should I do if I receive an enquiry letter from HMRC?
A.
Don’t panic, but act quickly! Most HMRC enquiries have strict deadlines for responses so we recommend you get in touch with us as soon as possible. You should also make sure to contact us before responding or providing any information as your initial response can significantly impact the direction and outcome of the investigation.

My wife and i booked a consultation with Omar at Aswatax recently. He provided exceptional advice on property incorporation, offering insights that even our accountant hadn’t considered his recommendations were awesome and we are now implementing them. I highly recommend him to anyone seeking expert guidance on property incorporation or tax matters. Thank you, Omar!

I first spoke to Omar over a year ago where we spoke about a Group structure and its benefits. Omar answered my questions, was patient and wasn’t pushy. I knew he was at the end of the phone when and if I received to go down that route.
Eventually when we were ready to move forward with a Group structure Omar made everything simple to understand and the process has been a great experience.
