Setting up a UK subsidiary from the United States

US companies usually arrive with a signed UK customer or a first UK hire, and a CFO who wants the entity to disappear into the group’s existing processes. That is what we build for.

What changes for US businesses

Five things we handle differently for you

01

Structure: a UK Ltd owned by the US parent

A private limited company owned 100% by your Delaware C-corp (or LLC) is the standard. A UK Ltd is an “eligible entity” for US tax, so your US advisers can make a check-the-box election on Form 8832 to treat it as disregarded if that suits the group; a UK plc cannot. We coordinate incorporation timing with that election.

02

Tax: treaty, GILTI and no dividend withholding

UK corporation tax is 25% (19% on small profits, thresholds shared across the worldwide group, so most US subsidiaries pay 25%). The UK charges no withholding tax on dividends to the US parent. Your US advisers handle Form 5471 and GILTI; we give them a UK tax computation in a format that drops straight in.

03

Year end and reporting

We set the UK financial year to 31 December to match yours, close the books monthly, and can map UK FRS 102 accounts to your US GAAP chart of accounts for consolidation.

04

People: the totalization agreement

The US–UK social security agreement lets US employees seconded to the UK stay on US social security for up to five years with a certificate of coverage. Local UK hires go on UK payroll with auto-enrolment pensions. Employer National Insurance is 15% above a small threshold — budget for it.

05

Banking

Revolut Business onboards US-resident directors online where eligible and gives you GBP and USD accounts side by side; traditional UK banks are supported where you qualify. Approval cannot be guaranteed.

Common questions from United States

Your FAQs answered

Should we use an employer of record instead of a UK entity?
For one hire and no UK sales, an EOR is faster. Once you are contracting with UK customers, hiring more than a couple of people, or want the UK P&L inside the group, a subsidiary is cleaner and usually cheaper within a year.
Do we need a UK-resident director?
No. UK law has no residency requirement. A US officer can be the sole director, verified remotely with Companies House.
Will the UK subsidiary need an audit?
It depends on the worldwide group, not the UK company. If the group exceeds two of £15m turnover, £7.5m balance sheet and 50 employees, the UK company needs an audit even if it is small. We check this at set-up.
Can the UK company invoice in USD?
Yes. Invoices can be in any currency; the books and tax returns are kept in GBP.
