Private Client


Sangna specialises in tax and estate planning for UK and international clients. She specialises in UK tax planning for non-domiciliaries and has particular experience in US-UK tax planning. In particular, she focuses on wills, trusts and alternative structure-based planning for high-net worth individuals. Sangna’s areas of expertise are UK and international tax, trust and estate planning. Within this diverse area, she has a particular focus on cross-border estate planning, dealing with the complexities created by local succession and matrimonial property regimes, the impact of the EU Succession Regulation within Europe, and the interaction of UK and local tax laws. Sangna believes in an integrated approach to estate planning that encompasses succession laws and asset protection considerations, as well as purely tax-driven strategies.

Sangna acts for several ultra-high net worth international families and their family offices. She advises them on their lifetime tax planning (eg the remittance basis of taxation and lifetime trusts), together with complex international estate planning.

She has a particular focus on US-UK estate and tax planning, having acted for many clients exposed to both tax and estate planning regimes. Sangna is also an expert on inheritance tax treaties, and contributed the chapter on domicile for inheritance tax for Clarke’s Offshore Tax Planning.

Sangna is listed as a Spears 500 2021 ‘Recommended Tax & Trust Lawyer’ and as ‘One to Watch’ in Legal Week’s Private Client Global Elite.

Sangna is admitted to practise in England and Wales.


  • Designing and implementing practical and effective succession plans for individuals, couples and families to ensure wealth is protected for future generations against the threats of tax, possible divorce, family disputes and financially immature heirs.
  • Advising US-UK clients on the effective use of trusts and other entities for estate and tax planning. In this context, Sangna regularly advises on:
  • the appropriate interpretation of various US entities (including revocable trusts and LLCs) for UK inheritance tax, income tax and capital gains tax purposes;
  • using trusts that qualify as both excluded property trusts and foreign grantor trusts to shelter assets from both US estate tax and UK inheritance tax;
  • the application of the US/UK double tax treaty to determine how trusts/grantors/settlors/beneficiaries should be taxed in each jurisdiction;
  • using the newly introduced UK “protected settlement” regime to enable UK and US taxes to be matched annually, without the need to bring trusts assets into the UK tax regime; and the various compliance regimes that affect trusts including FATCA, the CRS and the new UK trust register.
  • Using the US-UK double tax treaties to determine clients’ residence and or domicile for treaty purposes, and consequently their exposure to tax.
  • Estate-planning for couples with both a US and UK element, to minimise their incidence of UK and US estate taxes and, where necessary, taking into account matrimonial property regimes.
  • Advising clients on the UK tax rules relating to residential properties, related loans and holding structures.
  • Advising executors and trustees of family trusts and estates to enable them to carry out their responsibilities in such a way as to meet the families’ requirements.
  • Providing practical and tax efficient estate planning to a wide variety of families: from the traditional to the modern, such as unmarried couples or families where there are children from more than one relationship.
  • Advising owners and managers of successful businesses on tax efficient succession planning and, where appropriate, pre-sale structuring to maximise returns.
