Get help if HMRC contacts you about a compliance check (original) (raw)

1. Use the online tool

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

The tool signposts you to guidance and videos which provide support throughout your check.
