Setting up a UK company from Ireland: the practical guide

Since Brexit, a lot of Irish businesses have discovered that selling into Great Britain is smoother with a UK presence: a UK limited company, UK VAT number, GB EORI, sterling banking, and a UK address that couriers, marketplaces and customers recognise. The good news is that none of it requires living in the UK — Irish residents can own and direct a UK company entirely from Ireland. Here's how it actually works.

Can an Irish resident own a UK company?

Yes, completely. There is no residency or nationality requirement for directors or shareholders of a UK limited company — an Irish citizen living in Dublin, Cork or Galway can be the sole director and sole shareholder. What the company must have is a UK registered office address (we provide one) and, since November 2025, identity verification for its directors, which is done from your phone. Non-resident directors also need a certified or notarised proof of address for the anti-money-laundering checks.

Why Irish businesses set up UK companies

• Selling on UK marketplaces: Amazon UK and similar platforms treat a UK entity with UK VAT very differently from an overseas seller — fewer withholding complications and faster onboarding.
• UK customers and tenders: British B2B customers, councils and platforms often prefer (or require) contracting with a UK-registered company.
• Customs and VAT: a UK company with its own GB EORI and UK VAT registration imports into Great Britain in its own name, reclaiming import VAT properly instead of losing it in the supply chain.
• Sterling banking and payments: UK acquirers and banks onboard UK entities far more easily.
• Northern Ireland operations: if you trade in or through NI, remember NI is UK jurisdiction — a UK (or NI-registered) company is the natural vehicle, and our Northern Ireland pages cover every town from Belfast to Enniskillen.

What you'll actually file each year

A UK company owned from Ireland files the same things as any UK company: annual accounts, a confirmation statement, and a corporation tax return to HMRC — plus VAT returns if registered and payroll if it employs anyone. UK corporation tax applies to the company's profits. Your personal position stays governed by Irish tax residence and the UK–Ireland double taxation agreement, so profits aren't taxed twice — but the right salary/dividend mix differs from the standard UK advice, and it's worth getting a view on your numbers before the first year end, not after.

The honest caveats

• A UK company doesn't move your tax residence: if the company is managed entirely from Ireland, Irish 'central management and control' rules can matter. For most trading companies with genuine UK activity this is manageable — but it's a real question to ask, and we'll tell you straight if your setup needs Irish advice alongside ours.
• Don't register for UK VAT before you need to: the £90,000 threshold only counts UK taxable turnover, and voluntary registration has real pros and cons for a seller based in Ireland.
• Keep the Irish side clean: your Irish accountant handles Revenue; we handle Companies House and HMRC. The setups work best when both sides know the other exists.
