ADR Application Help

Submitting an ADR application to HMRC involves more than filling in a form; it requires crafting a clear, persuasive request that outlines the dispute and signals your readiness to mediate. HMRC accepts ADR applications once you have either received a closure notice from a compliance check or the outcome of a statutory review. Your application letter or online form must quote your tax reference, specify the issues in contention and include a brief history of previous discussions with HMRC.

It is also helpful to state any documents you will rely upon, such as audit logs, financial statements or expert reports. HMRC’s ADR guidance suggests using plain English and avoiding legal jargon, which underscores the importance of drafting a concise, well-structured application.

Effective ADR application help begins with a checklist of required details: taxpayer name, reference numbers, nature of the dispute and date of the decision letter. Next, you draft an introductory paragraph summarising the disputed points and your desire to resolve them without tribunal. You then list each issue in bullet points, with a short factual background and the legal question involved. Finally, you request the appointment of an independent mediator and propose convenient dates for the first joint meeting. 

After submission, HMRC usually acknowledges within 10–15 working days and confirms the mediator’s identity within a month. Throughout this period, HMRC should be kept informed of any changes—such as new evidence coming to light—to maintain transparency. A proper ADR application helps ensure your request is not delayed or screened out due to technicalities, setting the stage for a smooth mediation process.
