Two Things Every American Here Runs Into
Your US Taxes Follow You to the UK
Americans and US Green Card holders living in the UK are required by law to file a US tax return each year, on top of anything HMRC expects. Moving to the UK doesn't switch that off. We keep both sides aligned so you are never taxed twice on the same income.
It's the Reporting That Catches People Out
Beyond the return itself, US persons in the UK may be subject to FBAR and/or FATCA reporting requirements, plus PFIC reporting on certain funds. Missing these is where the real penalties live, so we map your full reporting footprint before anything is filed.
Compliance and Consulting, Handled Together
US Tax Compliance (UK)
Individual clients come to us with complex, multi-jurisdiction tax issues related to cross-border employment and investment opportunities. Similar to an interpreter or guide who helps travelers understand the language and customs of a particular country, we explain tax concepts and laws that are foreign to our clients. We prepare U.S. federal and state income tax returns for U.S. expatriates, foreign nationals and individuals with international financial interests.
US Tax Consulting (UK)
Our international tax consulting expertise includes analysis of tax treaties, sourcing of income, and reporting of foreign bank accounts, as well as foreign corporations, partnerships and trusts. As consultants, we help individual clients develop cost-effective strategies, propose solutions and prepare individual tax projections. We also work closely with our clients' attorneys and other advisors to provide comprehensive advice.

A Track Record US Expats Trust
In Their Own Words
Derren has made my life easier as a US expat living overseas. I haven't lived in the US since the 80's, and have run businesses in France and Singapore. Derren has helped eliminate a great deal of burdens and worries for me.
I highly recommend Derren. I have been his client for a number of years now and as an expat in Singapore have relied on his professional and timely service. He will answer immediately any question you have regarding taxes no matter how complicated (or simple) and help you navigate the process in a seamless fashion. A real professional!
Excellent service from Derren, he answered all questions quickly and thoughtfully pertaining my situation. I would highly recommend him for tax returns to the USA! Thanks again.
Derren Joseph were able to help us in our US Tax Compliance performing a detailed review of the last 9 years ensuring that all requirements of the IRS are fully satisfied. He is very helpful to our queries irregardless of the day and time. A customer service that you cannot find to any of the consultant out there... Highly recommended not only because of his credentials but also because of his professional work ethics.
Derren was very highly recommended by business friends to solve my very complicated US Tax problem. From our very first meeting he was friendly and easy to understand... His knowledge of IRS requirements and regulations is supreme. He produced the final results on IRS forms much sooner than expected. I highly recommend Derren for any US Tax matters.
I worked with Derren for my US personal tax return after a friend referred him. I found him to be very knowledgable about any issue asked, and equally important for me, to be very promt with responses. His was a very high quality work with excellent customer service. I used other tax services in the past and can say with confidence that Derren's was a grade above.
