Trusted by clients facing tax issues on both sides of the Atlantic.
Individual
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.

Working with DY USA has given us real confidence that our US structure and tax obligations are set up properly. They take complicated issues and explain them in a way that makes sense, which saves us time and allows us to focus on running and growing our business.

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.

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!

The reason we refer our clients to DY USA is simple, no one is as knowledgeable or as supportive to UK business navigating the US tax landscape than DY USA. The US tax system is incredibly complex and easy (and costly) to get wrong when you don’t know what you’re doing. DY USA has supported our clients for many years to communicate clearly what they need to know and provide them with honest and accurate advice for both their short-term needs and long-term goals.
If you are a UK business with US clients or offices, then there is no one better to support you with your trans-Atlantic tax needs than DY USA.

Business
We were setting up a new business in the US and our UK accountants were not able to provide the accounting expertise needed. I met with Rob Whittall through an introduction by our UK accountants and thought Rob was very impressive. He understood the differences between UK and US accounting and gave me confidence that he would be able to help us to safely navigate the challenges associated with starting up a new business in California.
DY USA worked with us on compliant tax filings with the IRS and California and exceeded my expectations.
The team at DY USA provides a positive mix of formal, professional service with a friendly personal approach. I trust in DY USA’s guidance, and their support is incredibly valuable. Their expertise has enabled me to focus on growing the business as opposed to trying to manage the myriad of accounting compliance that comes along with operating in the USA.
DY USA provides important accounting support (advice, guidance and compliance support) in a very responsive way. They assign a dedicated accountant to support our business, so we get access to someone who is familiar with our business and the way we work. This is very important to us.
