High Net Worth Unit

What is the High Net Worth Unit?

The High Net Worth Unit (HNWU) deals with the tax affairs of HM Revenue & Customs (HMRC) wealthiest individual customers. By focusing primarily on this customer group, the unit aims to:

  • build relationships to better understand these customers and make it easier for them to pay the right amount of tax
  • tailor service delivery for these customers through proactive engagement and provide a single point of contact and a holistic approach to their tax affairs

HNWU is made up of about 400 staff in 31 customer teams based in Birmingham, Bradford, Cardiff, East Kilbride, Edinburgh, Portsmouth, Washington and Wrexham.

A large number of staff working in HNWU are from the previous Complex Personal Tax Team and have experience in a wide variety of tax specialisms.


What happens when HNWU deals with your tax affairs?

When the unit takes ownership of a customer's tax affairs, both the customer and their authorised tax agent or adviser will receive a letter welcoming them to HNWU. This letter also contains contact details for their Customer Relationship Manager.

HNWU will continue to work with agents to identify suitable customers for the unit. If you believe HNWU has not classified you or your client correctly, you can write to them and provide a short breakdown of the value of the assets you or your client control. Please send your letter to:
