We started using Nick when we moved to the UK for 2 years with my company and we were so grateful for his help year after year. I should note, that as part of my relocation package, I was provided with “tax advice” UK by a large accounting firm. After the first year I was very disappointed. They were hard to get a hold of, didn’t ever answer questions, and were tedious to work with. I never understood anything the way they explained it. So the next year, I also Nick – meaning, I paid out of pocket when I didn’t have to – because my husband had had such a great experience. And I did too! Nick was a pleasure to work with. Responsive, friendly, and the best part – I understood everything he told us. He made taxes easy to understand! I recommend him to anyone I know who is an expat and will continue to do so based on the experience I had! Thank you!

I have been very impressed with the professionalism, knowledge and work ethic that these accountants offer. Nick not only made the process of filing a UK tax return painless and hassle-free, but he also did so on a very short notice. I’m glad I finally found an accountant who takes the pain of tax returns away and I can wholeheartedly recommend his advice!

Awesome! As an American Living in the UK, the thought of managing so many nuances of international taxation drove me to tears. Luckily Nick and his colleagues really took good care of me quickly and efficiently. I am so very pleased with the efficient, thoughtful, and dedicated service I received. It feels personalised yet efficient. I am 100% satisfied and will be coming back for years to come!  Well done and keep up the great work. This is truly a great company with great people. Many thanks!

Nick did a great job with my UK taxes, answering all emails promptly and clearly answering any questions I had. Reasonable rates and little effort needed on my part.

Wow. The most responsive service I have used in quite a while. From the moment I shared what I thought was a very intricate set of circumstances, Nick was able to confidently and enthusiastically take charge of the situation and explain everything in a clear and executable manner. In the end I will end up earning money from having worked with him to help understand the relationship between my US and UK tax returns. Very easy decision to go with them again in the future. Thank you.

With Nick Smith walking my husband and I through our UK tax returns and one of his colleagues on the US side we feel that we are in very good hands! Paying taxes in two countries is a bleak task, but Nick and co have made the process as seamless as possible for us. They are efficient, knowledgeable and most importantly kind. I recommend him to other expats.

Nick was incredibly quick, clear, and helpful in preparing my UK taxes. Thank you for making a dreaded task one I could quickly tick off with a smile!

Nick Smith is an absolute pleasure to work with. My tax situation was especially complicated this year. He patiently and diligently guided me through the whole process while doing all the hard work in the background. I can’t recommend his services highly enough. Worth every pence!

SUPER! Nick Smith and his colleagues are a dream team – supremely responsive, diligent, and on top of things. I feel very well taken care of….as an American expat in London for a while now, I finally feel as if I found a company which understands my particular challenges and offers the best advice I can get. Would highly recommend them!

I have worked with Nick for the past two years and would not want to work with anyone else. Nick and his colleagues have relieved me of all the frustration of ex-pat tax preparation, and they have done it with competence, efficiency, patience, and great good humor. For me, working with them has been both profitable and fun.

Nick and Lauren prepare my UK and US tax returns respectively. They are both great at what they do. Furthermore they are both patient with my questions and knowledgeable in their country’s tax requirements. I like that they have taken to collaborating on my Returns and explaining the different options I have with regards to my specific situation. This is where the value is for me. Cheers and thanks for all of your help!
