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.

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.

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 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.

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.

Answers
Unlike VAT, sales tax is not always charged or collected, and there is no reclaim process at the end of the year. Sales tax rules are set at the state level, meaning each state determines what goods and services are taxed.
Nexus refers to the minimum connection a business must have with a state before the state can impose tax obligations. Nexus can be created through physical presence—such as an office, property or employees — or through economic presence, which occurs when a business exceeds a state’s sales or transaction thresholds even without any physical operations.
US health insurance is often expensive, and employers rarely cover 100% of employee premiums. Businesses can choose from a variety of individual and group health plans and coverage options, but they must provide consistent, nondiscriminatory coverage across employee groups to stay compliant.
The UK has a more centralized system with fewer filing layers and unified reporting. In contrast, US accounting firms are highly specialized across tax, audit, and advisory due to a complex, multi-layered tax system, varying state-by-state compliance requirements, and the fact that US tax issues often arise early in a company’s US expansion.
There is a significant difference between what financial data is publicly disclosed in the US and UK for small businesses. In the UK, most entities are required to file statutory financial statements to Companies House, making their information public. In the US, only publicly traded companies are required to disclose financial data. Information filed with the IRS is confidential and can only be shared with the taxpayer’s consent.
In the US, this is an important decision, which should be made with guidance from trusted, experienced advisors. Key factors include owner liability protection, funding plans, tax treatment, and the business’ ownership structure.
There is no single best state to form a US entity. The right choice depends on your business model, customer base, and long-term goals. After your due diligence, consult legal and accounting advisors to evaluate each state’s liability protection, tax obligations, and compliance requirements to most suitable location for your US entity.
Processing payroll in the US can be complex. Employers typically choose from three service models:
US banks operate under strict compliance and internal-control frameworks due to the size of the market and higher fraud-risk exposure. As a result, opening a bank account typically takes longer and requires detailed reviews of ownership, control, and documentation. Electronic payments often require additional approvals and formal authorization records. Overall, US banking tends to be more costly, reflecting the heightened compliance, monitoring, and risk-management requirements.
