Delivering excellence to Expats since 2010


About Us

Thorne Expatriate Tax Services Limited specialises in US and UK Tax Return preparation and tax advisory services for individuals and was established in April 2010 by Michael and Sara Thorne.

“Our aim is to provide a personal service to our clients at competitive rates, with an open and friendly approach founded in the principles of professionalism, responsiveness, integrity and trust.  It is important to us that we work closely with our clients and that our clients have a personal working relationship with their tax adviser”.

Michael Thorne heads up our team of expat tax specialists. He has over twenty five years’ experience in providing US and UK tax services for expatriates.

Our clients are predominantly expatriates living and working outside their home country and include:-

  • American citizens and Green Card holders living and/or working outside the US
  • Foreign nationals living and/or working inside the US
  • UK nationals living and/or working outside of the UK
  • Overseas nationals with non-domiciled status living and/or working in the UK
  • Companies with employees sent on assignments to overseas locations

We take pride in the fact that we are predominantly a referral based business and we know how important it is to have trust in the person who is preparing your taxes.  We are always happy to provide references however you will see our unsolicited testimonials throughout our website.

Our offices are based in the village of Send in rural Surrey alongside the Wey Navigation Canal, but still only three miles from Woking railway station (with fast links to London) and from the M25.

Client Testimonials

Michael was recommended to me by my US tax advisors as the best you can find in the UK - he has been my trusted go to person on all tax related issues, and is simply fantastic. 

Ms S, United Kingdom

I just want to say how grateful I am to you and your team for the great work and support you have given me

Mrs S, United Kingdom

I highly recommend Michael Thorne.  Michael has been handling my taxes (as well as the taxes of many of my colleagues) since 2007.  He is organised and understands the frustrations/challenges of dual residency.

Ms P, United Kingdom

Many thanks again for such wonderful service from everyone.  Previous experiences with other accountants are left well behind yours by miles. 

Mrs M, United Kingdom

Thanks for the quick response, as usual. It's such a relief to have finally found an accountant that responds the way I would expect. Thank you.

Mrs K, United Kingdom

Please thank the team for the excellent service!

Mr Duc, United Kingdom

Thank you very much for the help organising our UK tax affairs, we wouldn't have been able to do it without you. 

Mr S, New Zealand

Thank you for your help, as always. I don't know what we'd do without your firm.

Mr S, United Kingdom

I have always enjoyed working with you and your team. The entire process has always been superb. I remain delighted to recommend your services to friends and colleagues now and in the future.

Mr H, United States

I searched high and low for a competent CA who understood US and UK taxes…and critically, how they mesh.  The ones I found before you ranged from the grossly incompetent to the highly competent, but grossly expensive. You turned out to be the best of both worlds…highly competent, but not unaffordably expensive.  I’d like to share my discovery with others.  

Mr N, United Kingdom

I just wanted to write a quick thank you for all your help over the years. You have been a trusted and deeply reliable advisor to me and it has meant a great deal. My taxes were by no means straight forward but I always felt extremely secure with them in your hands. 

Mr B, United States

I would like to say how much we have valued your efficient service and great help!!

Mr G, United States

Very grateful for your professional service.

Ms P, Singapore
