HMRC launches new online interactive help for compliance checks

1 May, 2025

We have worked with HMRC to co-create the new free online Interactive Compliance Guidance tool to help taxpayers understand HMRC compliance checks.  

It brings together links to various GOV.UK information about compliance checks into one place to help taxpayers easily find compliance guidance and the extra support available.  

The Interactive Compliance Guidance tool includes a variety of written guidance, supporting videos and information on what taxpayers should do next in the check.  

Information is structured to follow the flow of a compliance check, helping to simplify and demystify the process:  

  • HMRC compliance checks
  • Why HMRC has requested specific information or documents
  • How to request extra support due to health or personal circumstances
  • How to appoint someone to act on your behalf
  • What to do if you disagree with a decision made by HMRC
  • How to pay a tax assessment or penalty 

This is a valuable taxpayer aid designed to support taxpayers throughout the compliance check - from receiving an opening letter, through to making payment and finding out about debt support. 

How to access the tool 

Taxpayers will be signposted to the tool in compliance correspondence and by their caseworker throughout a check. Alternatively, they can access the tool directly by searching Compliance Check on GOV.UK or going to www.gov.uk/hmrc/taxcompliancehelp.
