Business Partner
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.

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 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.

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.

Individual
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.

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.
