I’m an American citizen who started a business in the UK. I chose DY USA because their team has not just read the guidance about being a dual citizen, they have lived it and faced the same challenges I do.

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.

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.

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 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!

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.

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.
