Trusted by clients facing tax issues on both sides of the Atlantic.
Individual
As a British citizen living and working in the United States, navigating cross-border tax requirements isn’t something I’d feel comfortable managing on my own. From day one, Rob Whittall and the DY USA team have made the process straightforward, clear, and stress-free.
They’re responsive, knowledgeable, and always willing to explain things in plain English, which gives me real confidence that everything is being handled correctly. It’s a huge weight off my shoulders knowing I have a trusted partner looking after both compliance and planning.
Working with DY USA has saved me time, removed uncertainty, and allowed me to focus on growing the business, rather than worrying about tax.
I wouldn’t hesitate to recommend them.

Business
We were naïve to the numerous filing requirements and US legislation, and our US accountant at the time was not knowledgeable about international companies. When I came across Rob Whittall, he explained the requirements simply and pointed out where we needed to alter our approach.
I am relieved that our business and taxes are in safe hands and delighted to have chosen DY USA as our accountants. We tidied up numerous historical inaccuracies and created a straight-forward and transparent correction with the IRS.
One of the most value pieces of working with DY USA is its one-to-one efficient system. The human element is so valuable, and time is freed up without lots of typical digital back and forth. If I have a question, it is answered swiftly and efficiently at any time. It’s not the typical annual scramble – everything works smoothly to a process but with a personal touch every time.
I recommend DY USA to anyone working transatlantic businesses!

I’m very pleased with the relationship we’ve developed with DY USA. The team obviously knows what they are doing and communicates clear and practical guidance for handling UK-US business and personal taxes. DY USA’s ability to fully address the cross-border taxes our company faces plus the guidance Rob provides based on his firsthand experience as a fellow business owner have been invaluable.

Business
We’ve really enjoyed working with DY USA and see them very much as a trusted partner rather than just an adviser. From the start, the team took the time to understand both our business and the realities of operating across the US and UK, which made a big difference. Their advice is always clear, pragmatic, and grounded in what actually works for us commercially.
Just as importantly, they’re extremely responsive and easy to work with. We always feel supported, well informed, and confident in the decisions we’re making with DY USA alongside us.

Business Partner
We regularly refer clients to DY USA when they are expanding into the U.S. and facing complex tax, entity structuring, and compliance challenges that sit outside UK expertise. What stands out immediately is DY USA’s ability to explain complicated U.S. tax matters in a clear, practical way, while still being technically robust.
Our clients value the responsiveness, clarity, and human approach of the DY USA team. Expectations are consistently met, and often exceeded, particularly around cross-border coordination and avoiding unnecessary risk or surprises.
Having DY USA as a trusted partner means we can confidently support clients scaling internationally, knowing they are in safe hands from a US tax and compliance perspective. The collaboration feels seamless, aligned, and genuinely client-first.

I am a dual US/British citizen, originally American, who has lived in the UK since 1974. In 2015, DY USA started looking after my US taxes after decades of doing it on my own, with assistance of, at best, variable quality. During the 11 years since, they have provided a consistently excellent service, helping me navigate the complexity of preparing my US returns more efficiently and with less stress than before. I particularly appreciate the personal attention that DY USA offers; it’s a great comfort to be able to communicate with friendly people I have come to know and trust.
