How is a UK interior designer taxed on US project work?
A UK-resident designer is taxed by HMRC on worldwide income, including fees from US clients and projects. If you spend significant time or have a fixed base in the US, some income may also be US-taxable. The US-UK treaty and foreign tax credits usually prevent double taxation, but both filing positions must be planned carefully.
How do VAT and US sales tax apply to design fees and furnishings?
In the UK, design services and the supply of furniture and fittings are generally subject to VAT, and the place-of-supply rules determine whether overseas clients are charged. The US has no VAT, but state sales tax often applies to tangible goods such as furniture you purchase and resell. Cross-border projects need careful indirect-tax mapping.
How should I handle purchases and mark-ups on furniture and materials?
Whether you buy goods as principal and resell with a mark-up, or purchase as the client's agent, changes the VAT, sales-tax and income treatment significantly. In the US, reselling tangible goods can create sales-tax collection duties and nexus in multiple states. We help structure procurement so margins are clear and indirect taxes are handled correctly.
Sole trader, LLC or limited company — what suits a design studio?
The best structure depends on profit levels, liability, and whether you have US or UK clients and staff. A UK limited company or US LLC each carry different tax and reporting consequences, and US-connected owners may face Form 5471 or partnership filings. We compare structures across both tax systems before recommending the most efficient option.
Can I deduct showroom, travel and sample costs across both countries?
Legitimate business costs such as samples, showroom space, professional software, and travel to client sites are generally deductible, but the US and UK have different rules on what qualifies and how it is recorded. Cross-border travel and home-office claims need particular care. Good record-keeping ensures you claim correctly in whichever country the income is taxed.
