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.

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.

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
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.

Consistently reliable and ahead of the curve. As a US commercial lawyer who rises or falls on my own reputation, I’ve been referring my clients to the attentive care of DY USA for 15 years, and always received outstanding feedback and results. Trust in excellence and integrity is essential in this business, and on that basis, I have no hesitation in recommending Rob and his team to bring the most up-to-date knowledge and professionalism to any task and any client they take on. Client well-being is always paramount to DY USA, and they value going the extra mile. I look forward to many more years of collaboration with this truly fine group of professionals.

We were unfamiliar with how the tax system works in the USA and certainly how to mix UK and USA tax requirements made it more challenging. Our initial conversations with Rob were the determining factors for our decision to move ahead with DY USA. We also needed to be certain that DY USA would have the tools to manage USA and UK accounts with local staff in each country. It felt re-assuring that we would engage with a firm that had the people, the experience, and the energy to partner with us along the journey. Plus, we liked the one-to-one feeling of having the same person dedicated to our business, rather than other firms (perhaps bigger and less personal touch).
DY USA always managed to get the figures, consolidation, and reports to the Board within a few days of month-end. That was one of the most important requirements for us plus the fact that they were able to effectively work with our accountancy platform.
The most valuable part of working with DY USA is the people. To start, Rob helped the organization with first steps towards moving to the US, followed by Joe and then Joel as our Account Managers. Never a bad word, slow, or negative. The personal touch by their team clearly helps them stand apart from other firms. I would highly recommend and would use myself should the opportunity arise again.
