HMRC Compliance Check

HMRC Compliance Check

A compliance check is HMRC’s review of the accuracy of a submitted tax return. Understanding what a compliance check involves and how to manage it effectively is essential to protecting your interests.

What is a Compliance Check?

HMRC compliance check letters arrive in various formats. Some are targeted at specific entries on a return, while others are broader reviews of overall tax affairs. Regardless of the format, the purpose is the same: HMRC is reviewing the accuracy of the information you have submitted.

HMRC’s Powers

HMRC has the power to request documents and information relevant to the check. These powers are extensive and can cover business records, bank statements, contracts, and any other material that HMRC considers relevant to verifying the accuracy of a return.

The Risks

Without proper representation, there is a real risk of a routine compliance check becoming an extensive inquiry. Unrepresented taxpayers may inadvertently provide information that widens the scope of the check or raises further questions that would not otherwise have arisen.

Time Limits

There are no statutory time limits governing how long HMRC can take to complete a compliance check once it has been opened. This means that:

• Proper management of the check, with focused and strategic responses, typically resolves matters quickly
• Poor handling, including delayed responses, incomplete information, or inconsistent explanations, can extend checks over months or even years

Penalties

Following the conclusion of a compliance check, HMRC may impose penalties if inaccuracies are found. The level of penalty depends on:

• The behaviour that led to the inaccuracy (careless, deliberate, or deliberate and concealed)
• The level of cooperation and disclosure provided during the check

Penalties range from 0% for unprompted disclosure of careless errors to 100% for deliberate and concealed inaccuracies with no cooperation.
