Expatriate Tax Advisory Service Limited

Founded in 1995 in the Surrey Hills, we are a family-owned tax practice with UK and US qualified tax consultants. We provide tax advice and prepare tax returns for British and other individuals, living in the UK or abroad.


Any individual could potentially be one of our clients and we are always pleased to hear from prospective clients. Most, but not all, clients have an expatriate connection, but some have none. Clients include British nationals working for UK or other companies abroad and those who have property or other assets including investments abroad. We also act for non-British clients who may now be living in the UK or who have property or other assets or family or other connections in the UK. Remember that US citizens need to file US tax returns based on their worldwide income, wherever they live. Many clients need advice on residence and domicile and we also prepare property tax returns. Employers also provide our contact details to their staff if they need expatriate tax advice and UK or US tax returns prepared as a result of a work assignment.

We provide continuity of service for our clients and help them sleep well at night by answering their tax questions, providing UK and US tax advice, and preparing their UK tax and US tax returns.
