Guidance
Get help if HMRC contacts you about a compliance check
Use the online tool throughout a check to guide you through each stage and to access the support available.
A compliance check is when HMRC checks your tax position to make sure you have:
- paid the right amount of tax at the right time
- claimed the right allowances and tax reliefs
It is also to make sure that the tax system is operating fairly and effectively.
In a check, HMRC will:
- send you a letter and request information or documents
- discuss matters with you to understand your tax position
- establish the correct tax position for you and close the check
Use the online tool
The tool signposts you to guidance and videos which provide support throughout your check.
