HMRC’s approach to tax compliance for wealthy individuals and mid-sized businesses

HMRC’s Wealthy and Mid-sized Business Compliance (WMBC) Directorate aim to put our customers and their compliance at the heart of everything we do by taking a ‘customer segment’ approach, focusing on customers rather than different types of tax, so we can target and coordinate our responses more effectively.

We focus on wealthy individuals and mid-sized businesses as well as public bodies, trusts and charities, providing insight into the wealthy population, their tax affairs and the businesses they own or influence. We also deal with a wide range of risks, including employment status and intermediaries, Inheritance Tax and various incentives and reliefs.

We also have a key part to play in promoting and supporting the growth that mid-sized businesses bring to the UK economy. This is part of HMRC’s wider work to promote growth and minimise cost to business while maximising compliance.

Our approach is to increase voluntary compliance among these groups using approaches which promote compliance and prevent non-compliance and challenge those who break the rules.

In 2022 to 2023, WMBC achieved compliance yield of £5,902 million as shown in the table above.

Tax under consideration

Tax under consideration is an estimate of the maximum potential additional tax liability in each case before we have carried out a full investigation of the specific facts or analysis of relevant law. It is not actual tax either owed or unpaid, it is a tool to guide our enquiries to focus on the most significant risks that exist at any particular time.

In many cases, when we have looked at the full facts, it becomes clear that there is some lesser liability or even no further liability at all. Tax under consideration will naturally vary from time to time as outstanding issues are settled and new risks are identified.

The total is a snapshot of work in progress at a given point. Tax under consideration covers all taxes and duties, including but not limited to Income Tax, Corporation Tax, VAT, PAYE and National lnsurance contributions and Inheritance Tax.

A snapshot, as of 31 March 2023, of the tax under consideration figure for enquiries by HMRC’s WMBC Directorate is shown in the following table:
