Business & Self-Employment
Business structures rarely translate cleanly across the Atlantic. An entity that is sensible in one country can be a tax accident in the other — these guides cover the classic structures and their traps.
US LLC, UK resident
Why a US LLC that works perfectly for Americans can misfire for a UK resident: US pass-through treatment versus HMRC's opaque-entity view, the Anson case, double-tax risk, and when a different vehicle is the better answer.
Learn moreUK company, US owner
What US ownership does to a UK Ltd: controlled foreign corporation status, Form 5471 reporting, the GILTI regime for individual shareholders, why salary-versus-dividend planning changes, and the elections that exist to manage it.
Learn moreCross-border structuring
Sole trader, UK Ltd, US LLC or C-corp: how the main vehicles behave when two tax systems look at them at once, what check-the-box elections change, and why the right structure follows from your facts rather than from a list.
Learn moreFreelancers & consultants
What self-employed people with US-UK lives actually file: UK Self Assessment and Class 4 NIC, US self-employment tax and the totalization certificate that prevents doubling, IR35 and umbrella arrangements, and the £90,000 VAT threshold.
Learn moreEntrepreneurs
Launching as a US person in the UK, or a British founder expanding to the US: the registrations each side expects, the entity-choice pitfalls that are cheap to avoid and dear to fix, payroll versus self-employment, and when pre-formation advice earns its fee.
