Private Client Tax

The CMS Private Client Tax practice advises on all aspects of personal and corporate tax matters including income tax, capital gains tax, inheritance tax and stamp duty land tax.

CMS tax practitioners have experience across a range of practice areas and are well placed to advise family office clients and high net worth individuals ("HNWIs") on their tax affairs in order to optimise their tax position in relation to their properties, businesses and investments.

The CMS tax practice provides services and guidance in the following private client tax areas:

  • Residence and Domicile - helping HNWIs with all tax matters relating to moving to or from the UK.
  • Aircraft and Yachts - The importation of private aircraft and yachts into the UK raise complex VAT, customs duties and income tax issues. Facilitating the cross-border movement of these assets into and out of the UK, including advice on VAT and customs duties applications to HM Revenue & Customs ("HMRC") and related registration requirements.

This includes evaluating the effectiveness of tax schemes and any potential recourse against scheme promoters and advisers.

We also advise insurance companies, corporate clients and corporate trustees on the tax implications of excepted group life policies and establishing employee healthcare trusts.
