OUR SERVICE OFFERING
Investigations & Disputes
If you’re encountering problems in your tax situation, such as an HMRC investigation or dispute, K3 Tax Advisory can help.
Our Investigations & Disputes Tax Advisory Approach
Our goal is simple: to manage the risk, minimise the financial damage and guide clients with expertise, discretion and reassurance through what is often a stressful process.
Unlike forward-looking tax planning, our work focuses on resolving tax problems that have already arisen, whether through error, oversight, poor advice or deliberate wrongdoing.
We know that dealing with HMRC can be daunting, especially when under investigation. The following process is designed to protect clients from unnecessary stress, financial exposure and reputational harm.
Why Choose Us
- Initial Consultation:
We respond quickly – the same day whenever possible – as we realise most clients contact us in urgent circumstances. We assess the issue, explain your options and outline immediate steps to protect your position. - Fact-Finding and Review:
We gather all relevant information, review the tax history and determine what went wrong – and to what extent. - Developing the Strategy:
We determine the right disclosure route or defence strategy, focusing on minimising penalties and preventing HMRC from widening the investigation unnecessarily.
- Managing HMRC Interaction:
As former HMRC investigators ourselves, we know how to handle enquiries effectively. We take control of all communications, ensuring HMRC requests are proportionate and that clients are treated fairly. - Resolution and Settlement:
We negotiate directly with HMRC to reach the best possible financial and procedural outcome. This may involve significant reductions in tax and penalties, often by hundreds of thousands of pounds. - Aftercare and Compliance:
Once resolved, we help clients implement better procedures to prevent future issues and regain control of their tax affairs.
Our role goes beyond technical expertise. We guide clients through what can be a deeply stressful process, offering reassurance, empathy and confidence that the situation can be resolved.
Our Service Offering
If HMRC has already contacted you, or you have realised an error was made in your tax return, we can help in the following ways:
HMRC Enquiries and Investigations:
We act for clients facing HMRC investigations into underpaid tax, errors or alleged fraud. Whether HMRC has opened an enquiry or you wish to make a voluntary disclosure before they do so, we handle every stage of the process – from initial contact to final settlement.
Our work focuses on damage limitation, presenting HMRC with an accurate, defensible position to ensure they do not overreach. We negotiate fair outcomes that reflect the true facts, not exaggerated assessments.
Tax Fraud and Civil Investigations:
Most fraud cases are handled by HMRC under civil investigation procedures. We specialise in managing these complex cases by identifying what went wrong, quantifying the true position and negotiating reduced penalties.
Our aim is to protect clients from criminal prosecution wherever possible. We never assist in concealing wrongdoing; instead, we focus on achieving the best possible resolution through full disclosure, professional presentation and strategic negotiation.
Voluntary Disclosures:
Some clients discover issues before HMRC does, e.g. unpaid tax, incorrect reporting or errors made by previous advisers. We guide them through the voluntary disclosure process, presenting the facts in a way that demonstrates cooperation and transparency.
As we handle a large number of voluntary disclosures each year, HMRC trusts our approach and recognises our integrity, resulting in faster resolutions and significantly reduced penalties – or preferably none at all.
Tax Disputes and Appeals:
We also assist clients with technical tax disputes that are not fraud-related, such as disagreements over VAT exemptions, income classification or Corporation Tax treatment.
Our team will analyse HMRC’s position, build a strong technical defence and manage appeals through negotiation, alternative dispute resolution or formal appeal channels.
Accountant and Adviser Support:
Many cases arise due to issues in the accountant-client relationship, whether through miscommunication, incomplete records or lack of specialist knowledge.
We work collaboratively with accountants, solicitors and other advisers to resolve these matters efficiently and restore compliance.
Support in Criminal Matters:
In the rare event that a case escalates to a criminal investigation, we work alongside criminal defence lawyers, providing technical tax expertise and assisting them in understanding HMRC’s approach and evidence.
Why Choose Us
- Ex-HMRC expertise: Almost all our team are former HMRC investigators. We know exactly how HMRC thinks, how it builds cases and how to negotiate the best outcomes.
- Proven Track Record: We regularly reduce HMRC’s starting assessments by substantial amounts, to sometimes only a small fraction of the original amount.
- Trusted by HMRC: Our integrity and consistency mean HMRC trusts our submissions. We are known for providing honest, accurate disclosures that lead to quicker, fairer settlements.
- Specialist Focus: Few firms specialise solely in tax investigations and disputes. We are among only a handful nationwide with dedicated expertise in this area.
- Swift Response: Clients in difficulty need immediate support. We respond quickly and decisively to all enquiries, ensuring clients feel protected and understood from day one.
- Empathy and Reassurance: We understand the personal and emotional toll of an HMRC investigation. Our approach is calm, strategic and focused on reducing both financial and emotional stress.
- Collaborative Network: We frequently receive referrals from accountants, lawyers and insolvency practitioners who trust us to handle sensitive, high-stakes cases with care and professionalism.
Why Choose Us?
Whether you are facing an HMRC enquiry, a voluntary disclosure or a full investigation, our team provide the expertise and reassurance you need to move forward with confidence. We will protect your interests, limit the damage and restore peace of mind.
Frequently Asked Questions
What should I do if HMRC contacts me about an investigation or enquiry?
You should seek specialist advice immediately, before responding substantively to HMRC. Early action can significantly influence the scope, tone and outcome of an enquiry. We can step in at any stage, take over all communication with HMRC, and ensure your position is presented accurately and defensibly from the outset.
Can you help if errors or unpaid tax have already been identified?
Yes. Many clients come to us after discovering errors or underpaid tax themselves, often following due diligence or a change of adviser. We specialise in managing voluntary disclosures, presenting the facts clearly and transparently to HMRC in a way that demonstrates cooperation and typically results in reduced penalties — or, in some cases, none at all.
How do you handle allegations of tax fraud?
Most tax fraud cases are dealt with by HMRC under civil investigation procedures. Our role is to manage these cases strategically, quantify the true tax position, and negotiate fair settlements while seeking to avoid criminal prosecution wherever possible. We do not assist in concealing wrongdoing – instead, we focus on professional disclosure and robust negotiation to achieve the best achievable outcome.
Will you deal directly with HMRC on my behalf?
Yes. Once instructed, we act as your representative and manage all interaction with HMRC. As former HMRC investigators, we understand how enquiries are conducted and how to prevent them from becoming unnecessarily wide-ranging or adversarial. Our aim is to protect you from excessive demands and ensure HMRC acts proportionately.
