What a compliance check is
A compliance check is when HMRC checks your tax position to make sure that you’re:
- paying the right amount of tax at the right time
- claiming the right allowances and tax reliefs
It is also to make sure that the tax system is operating fairly and effectively.
A check involves:
- sending you a letter and requesting information or documents
- discussing matters with you to understand your tax position
- establishing the correct tax position for you and closing the check
