Stalled enquiries and tax appeals often need proper review

When HMRC Alternative Dispute Resolution Needs Specialist Advice

Many clients ask for help only after months of unproductive correspondence. HMRC may say its view is settled, an appealable decision may already have been issued, or a tribunal timetable may be approaching. In other cases, the enquiry has stalled because the facts, documents, technical analysis or commercial background have not been understood in the same way by both sides. The taxpayer may already know the dispute is unlikely to be resolved through ordinary letters and wants to explore HMRC ADR before matters become harder, more expensive or more entrenched.

These matters need careful review because not every dispute is suitable for ADR, and not every case should be handled in the same way. The right HMRC dispute resolution strategy depends on the tax involved, the stage the matter has reached, whether the real disagreement is factual or legal, how HMRC has framed its position, what evidence exists on both sides, and whether HMRC’s own Litigation and Settlement Strategy leaves genuine room for resolution.

Specialist mediation advice makes a difference

Why Work with an HMRC ADR Specialist Advisor

A specialist HMRC ADR adviser does more than read HMRC’s latest letter and repeat what it says. Good advice helps you understand whether the dispute is suitable for ADR, whether the facts can genuinely be challenged, what evidence may shift HMRC’s position and how the mediation process should be approached before the matter becomes more expensive, more entrenched or more difficult to resolve.

For some clients, that means applying for ADR before a tribunal process hardens the positions. For others, it means reviewing whether HMRC’s Litigation and Settlement Strategy leaves any room for practical resolution, preparing a coherent statement of the dispute, or managing the ADR process so the client enters mediation with a clear strategy rather than a hope that the meeting will somehow fix itself.

Reduce Risk

Identify factual weaknesses, settlement scope and tribunal exposure before the dispute becomes harder and more expensive to manage.

Get Clear Guidance

Understand what the dispute really involves, what may realistically be resolved through HMRC ADR and what practical steps should be taken next.

Deal with HMRC Properly

Approach applications, dispute summaries, mediation meetings and settlement discussions with HMRC in better structure and far greater confidence.

We support clients who want HMRC alternative dispute resolution advice to be clearer, more practical and easier to manage. Clients value responsive support, careful preparation and a more structured way of dealing with HMRC, mediation and tribunal risk where a dispute cannot be resolved through correspondence alone.

I received an appealable HMRC decision and was worried the matter would head straight to tribunal. Tax Accountant reviewed the enquiry history carefully, prepared the ADR application properly and helped me approach the mediation with far more confidence than I could have managed alone

David R

Property investor 

My case involved a long IR35 enquiry, disputed working practices and correspondence that had stopped making progress. The advice was clear, practical and much more useful than trying to deal with HMRC and the possibility of tribunal on my own.

Your Questions - Our Answers

We are here to help you with any questions you may have

What is HMRC alternative dispute resolution, and who runs it?

HMRC alternative dispute resolution is a structured tax mediation process in which an impartial HMRC mediator helps you and the HMRC officer explore a settlement outside the tribunal. HMRC runs the process internally, although taxpayers may bring their own accredited mediator at their own cost. 

HMRC ADR is voluntary, free of HMRC charge and runs without prejudice, although tax facts disclosed during mediation are not protected. Most cases conclude within four months of acceptance, and HMRC publishes outcome statistics each year showing strong settlement rates.

Our HMRC ADR specialist team assesses your suitability, decodes the correspondence, frames the issues, and manages the application end to end. We can challenge HMRC assumptions, draft your statement of matters in dispute, prepare you for the mediation meeting, and review the record of outcome. Clear documentation and disciplined preparation substantially improve the prospects of a fair settlement.

You can apply for HMRC ADR at almost any stage of an enquiry, including before any decision has been issued, during a compliance check, after a closure notice, after an appealable decision, and even once tribunal proceedings are under way. The 2020 tribunal practice statement positively encourages stays of appeal to allow ADR, and the tribunal will normally support a stay where mediation is genuinely viable.

For direct tax cases, ADR is available between the issue of a decision and the statutory review window. For indirect tax matters such as VAT, excise and customs, HMRC will not usually accept ADR after a decision has been issued unless an extension to the review window has been agreed first, so timing must be carefully managed.

If you have made an appeal to the First-tier Tribunal, HMRC asks that you wait until you receive the acknowledgement letter before applying for ADR. Statutory review and ADR cannot run at the same time, so sequencing matters significantly between these two routes.

Our HMRC ADR advisors review your file, identify the optimum moment to apply, protect your appeal rights, and guide you through the procedural choices. Getting the timing wrong can shut doors permanently, so a properly sequenced strategy across review, mediation and tribunal is essential from the outset of any tax dispute.

HMRC ADR is best suited to disputes where facts, evidence, assumptions or commercial substance are in genuine contest. Examples include disagreements about the place of supply for VAT, the commerciality of a transaction, IR35 working practices, R&D tax credit eligibility, capital versus revenue treatment, residence and domicile facts, transfer pricing, or whether expenditure qualifies for a particular allowance.

Cases under criminal investigation by the Fraud Investigation Service, tribunal cases categorised as paper or basic, automatic late-filing or late-payment penalties, complaints about HMRC delays, tax credit disputes, PAYE coding notices, National Minimum Wage cases and High Income Child Benefit Charge assessments are normally outside ADR.

HMRC will also decline ADR where it intends to take a test case to tribunal, where it has serious doubts about evidence and wants cross-examination, or where the dispute is purely a settled point of statutory interpretation with no factual element. Borderline applications go to the internal HMRC ADR Panel for a decision.

Our HMRC ADR specialist team runs a fixed-fee suitability check against the published criteria and the Litigation and Settlement Strategy. If ADR is not viable, we explain why clearly and recommend statutory review, tribunal preparation or further negotiation as the appropriate alternative dispute resolution route for your case.

Without prejudice means you and HMRC can freely propose and explore settlement options during the mediation without those discussions being treated as admissions if no agreement is reached. It is a long-standing legal protection designed to encourage open dialogue and creative settlement work between two parties who would otherwise be guarded.

In HMRC ADR, the protection has a sharply defined limit. Anything HMRC categorises as a tax fact, defined as a fact with legal or technical implications for your liability, is not confidential and not covered by the without-prejudice rule. Examples include the receipt of a payment, the making of a supply, the identity of a customer, the place of supply or the date a transaction took place.

Tax facts disclosed during mediation are recorded in the formal record of outcome and may be relied on by HMRC at tribunal or in future assessments. This makes preparation absolutely critical, because a casual concession during a long meeting can decide your tax liability quickly.

Our HMRC ADR advisors rehearse the meeting with this boundary firmly in view, brief you on what may safely be explored as without-prejudice, and ensure that no factual concession is given unintentionally. Skilled handling of this boundary is the single most important reason taxpayers should never enter HMRC mediation alone or unprepared.

HMRC aims to conclude accepted ADR cases within roughly four months from acceptance to outcome, although complex matters can run longer where additional evidence is required or further meetings are needed to bridge a remaining gap between the parties.

The standard timeline is straightforward. HMRC will normally tell you within thirty days of receiving your application whether the case has been accepted, although disputed suitability may be referred to the ADR Panel. Once accepted, the HMRC mediator contacts both sides and asks for the statement of matters in dispute, supporting documents and an outline of the proposed resolution. Information requests must be answered within fifteen working days throughout the process.

The mediation meeting itself is normally held within ninety days of application. Most meetings last a full day, with a joint opening session followed by private caucus discussions where the mediator shuttles between the parties. The record of outcome is drafted and signed shortly afterwards by all parties.

Our HMRC ADR specialist team keeps the timetable on track, responds promptly to mediator requests, and avoids the procedural slip-ups that lead to a case being removed from ADR. Missing the fifteen-day window without a proper extension is one of the most common reasons cases are taken out of the alternative dispute resolution process unnecessarily, so disciplined timetable management matters greatly.

The HMRC mediation meeting is the centrepiece of the ADR process. HMRC’s default position is now video or telephone, with face-to-face only where the mediator agrees it is necessary. Most meetings last a full working day, although some run longer where complex matters require additional time and further preparation between sessions.

The HMRC team typically comprises the original case officer, a senior counter-signing officer with authority to approve a settlement, the mediator, and occasionally HMRC technical specialists or solicitors. Your team usually includes you or your nominated representative, your tax adviser, and any factual or technical experts whose evidence is relevant to the dispute.

Meetings begin with a joint opening where each side summarises its position. The mediator then moves into private caucus discussions, exploring options and testing ideas with each side separately. The day concludes either with a settlement, a partial agreement narrowing the issues for tribunal, or a formal record that no agreement was reached.

Our HMRC ADR representation team attends with you, manages the without-prejudice boundary throughout the day, presents evidence persuasively, and ensures the counter-signing officer has the material needed to approve a settlement on the day. Some clients prefer not to attend in person, in which case we attend on your behalf with you available by phone.

A signed HMRC ADR settlement is binding once both parties have agreed and signed the record of outcome. In higher-value or sensitive cases, the agreement may need to be approved by HMRC’s internal Dispute Resolution Board or a similar panel before it becomes final, and the mediator will tell you clearly during the meeting if this approval applies.

Once the settlement is approved, HMRC issues revised assessments, amended penalty notices, refunds or other formal documents to give effect to the agreement. The record of outcome forms the only authoritative record of what was agreed and is the document we draft most carefully on your behalf.

If no agreement is reached, your appeal rights are completely preserved. The mediation will usually have narrowed the issues, clarified the facts, and given you a much clearer picture of HMRC’s position before tribunal, which often saves significant time and cost in any litigation that follows. Many cases that fail at ADR settle shortly afterwards on the doorstep of the tribunal hearing.

Our HMRC ADR advisors continue to support you whatever the outcome. Where settlement is reached, we implement the agreement and check the revised calculations carefully. Where it is not, we prepare your tribunal bundle, instruct counsel where appropriate, and represent you through to a final First-tier Tribunal hearing.

Yes, HMRC ADR is available for almost every direct and indirect tax dispute, including Income Tax, Corporation Tax, Capital Gains Tax, Inheritance Tax, VAT, PAYE, IR35 and off-payroll working, the Construction Industry Scheme, Stamp Duty Land Tax, customs duty and excise duty. Mediation is widely used in factually complex cases where evidence and commercial substance drive the outcome.

For HMRC ADR for IR35 and off-payroll determinations, mediation is particularly effective because the dispute almost always turns on working practices, control, substitution and mutuality of obligation, all of which benefit from face-to-face discussion. We have specific experience with personal service company and end-client disputes under the new off-payroll framework.

For HMRC ADR for COP8 enquiries into suspected tax avoidance, mediation is available and increasingly used, especially where the technical analysis of a planning arrangement has reached a deadlock. ADR is not available for COP9 cases under the Contractual Disclosure Facility while criminal investigation is live.

For HMRC ADR for VAT cases, the timing rules are stricter than for direct tax, so applications must be made carefully within the available window. Our HMRC ADR specialist team handles the full range of taxes and dispute types, including transfer pricing, R&D tax credit challenges, property tax disputes, residence and domicile cases, and large landlord portfolios.

Our role is to reduce stress, ensure accurate technical preparation, and protect your tribunal position. Our HMRC ADR specialist team reviews your file, assesses suitability, frames the issues, and drafts clear submissions for the HMRC mediator and counter-signing officer to consider promptly.

If you are facing a closure notice or tribunal listing, our HMRC ADR advisors prepare your application carefully, draft the statement of matters in dispute, and attend the mediation meeting with you. We ensure your evidence is concise, your timeline is clear and your settlement parameters are properly defined before the day. Should the matter require external counsel, we coordinate legal advice and adjust our approach accordingly. For penalty disputes, we prepare mitigation arguments and reasonable excuse evidence in proper structured form.

Where ADR succeeds, we review the record of outcome, check revised assessments, and confirm any agreed payment or recovery terms are properly implemented. Where ADR fails, we manage the transition to tribunal, prepare the bundle, brief counsel and represent you through to hearing.

Everything is managed through our secure portal where you can upload documents and track progress on your matter. We keep you updated with concise information and a clear plan, while communicating with HMRC, the mediator and the tribunal on your behalf at every stage. Call us for a quick review and a fixed fee.
