Can a British citizen form an Irish limited company post-Brexit?
One of the most widespread cross-border structures following Brexit falls into place through Irish limited companies owned and managed by British sole shareholders and directors. The Common Travel Area linking the UK and Ireland predates EU membership and endured Brexit without change, giving British citizens freedom to reside, work and access services in Ireland requiring no visa or permit.
British entrepreneurs have become the single largest foreign founder cohort incorporating Irish limited companies since the UK formally left the EU Single Market at the end of 2020.
The Irish Companies Registration Office (CRO) saw British-resident director filings increase substantially in 2021 to 2022 and remain elevated through 2026 as UK businesses seek continued EU market access, VAT simplicity for intra-EU commerce and dollar-friendly Irish banking infrastructure.
An Irish limited company is readily formable by British citizens, with the Common Travel Area (CTA) between the UK and Ireland offering a genuinely unique legal framework that smooths personal and business movement between the two countries.
This guide walks a British citizen through forming an Irish limited company in 2026: the CTA’s continued operation post-Brexit, CRO incorporation mechanics, the 12.5 percent corporate tax rate (with the new 15 percent for very large companies under Pillar Two), the EEA-resident director requirement and the bond workaround, banking at the Irish pillar banks, VAT and OSS/IOSS for EU B2C sales, and the costs in EUR and GBP from formation through year two.
Why Ireland Specifically for British Founders
Ireland offers British founders a combination that no other jurisdiction matches. First, full EU Single Market and EU VAT system membership, which UK companies lost with Brexit. Second, a 12.5 percent headline corporate tax rate (15 percent for groups with 750M+ EUR revenue under the OECD Pillar Two framework that Ireland adopted effective 2024), among the lowest in Western Europe.
Third, the Common Travel Area between the UK and Ireland that pre-dates EU membership and continues post-Brexit, allowing British citizens free movement, residence, work and social security access in Ireland without visa or permit requirements. Fourth, English as the working language. Fifth, strong fintech, pharmaceutical and technology sectors supporting sophisticated corporate services.
For UK businesses selling into the EU, an Irish subsidiary or sister company is often the cleanest way to maintain EU VAT simplicity, continue accessing EU B2C customers without OSS/IOSS routing through another member state, and handle VAT-registered EU supply chains.
Brexit created genuine friction for UK companies selling into the EU, particularly around VAT, customs and EU VAT One Stop Shop eligibility. An Irish limited company is not a tax haven, the 12.5 percent rate is a full corporate tax paid on genuine Irish-resident company profits. The commercial reason to form in Ireland is EU market access, not tax avoidance.

The Common Travel Area Post-Brexit
Before the EU, the UK and Ireland maintained the CTA, which gives:
- British and Irish citizens can move freely between the two jurisdictions without visa or permit
- Right to work in the other country without work permit
- Access to healthcare, social welfare, education on reciprocal terms
- Free residence in the other country
The CTA survived Brexit intact and is enshrined in a post-Brexit UK-Ireland Memorandum. For a British founder, this means moving to Ireland or commuting between Dublin and London is administratively unremarkable, comparable to moving between English regions.
For company formation purposes, the CTA is important because Ireland generally requires at least one EEA-resident company director.
UK directors post-Brexit are not automatically EEA-resident, but the CTA’s continued operation means British citizens residing in Ireland satisfy the EEA director requirement through their Irish residency, and the overall framework is more permissive than for directors from other non-EEA jurisdictions.
The EEA Director Requirement
Irish company law requires at least one director to be resident in the EEA (European Economic Area, which is the EU plus Iceland, Liechtenstein and Norway). Post-Brexit, the UK is no longer in the EEA, so a UK-resident director is not automatically EEA-resident.
Founders from Britain establishing an Irish Ltd have these options available to them:
- Relocate to Ireland. A British citizen can reside in Ireland under the CTA and thereby become Ireland-resident and thus EEA-resident for the director requirement.
- Appoint a Section 137 bond. Irish companies without an EEA-resident director can post a Section 137 revenue bond (typically 25,000 EUR) as an alternative to satisfying the residency requirement. This is a common workaround for UK-based founders who are not relocating.
- Appoint an EEA-resident co-director. Working alongside the UK-based British founder, a trusted business partner or professional service provider who resides in the EEA can fill the role of the second director.
- Retain an EEA-resident nominee director. Hiring a corporate service provider to retain an EEA-resident nominee director is less common because of fiduciary concerns.
Many British founders intending to run the Irish company actively use the Section 137 bond in year one and move toward an EEA-resident director as the business grows or they relocate.
Irish Limited Company Formation
The Irish limited company (Limited, Ltd or private company limited by shares) is the standard corporate form. Essential requirements include:
- One shareholder is required, and it can be a British citizen who is the sole shareholder.
- Every company requires at least one EEA-resident director or a Section 137 bond in lieu.
- Company secretary (can be the same as director in single-director companies, with specific rules)
- Registered office in Ireland
- Constitution (standard or customized)
CROs access incorporation through the CORE portal. Submission to registration takes 5 to 15 business days in total.
Irish corporate tax:
- 12.5 percent on trading income
- 25 percent applies to passive (non-trading) income.
- 15 percent under Pillar Two for in-scope groups with 750M+ EUR consolidated revenue
Ireland has no capital gains tax on qualifying share disposals between Irish group companies, extensive DTA network and specific regimes for IP (Knowledge Development Box at 10 percent on qualifying IP income, raised from 6.25 percent effective October 2023).
Formation Step by Step
- Select a company name and check its availability using CRO.
- Draft constitution using standard Form A2 or customizing for more complex arrangements.
- Appoint directors, secretary, shareholders, registered office.
- Decide on EEA director or Section 137 bond.
- File via CORE portal (50 EUR fee standard filing).
- Certificate of Incorporation issuance happens in 5 to 15 business days.
- Register for Corporation Tax with Revenue Commissioners.
- Register for VAT if required.
- Open bank account. Open an account at AIB, Bank of Ireland, PTSB, Ulster Bank (though closing with residual services still available) or fintech platforms.
- Register as employer for PAYE/PRSI if hiring.
From start to finish, building a clean British-founder profile takes 4 to 10 weeks.
UK-Ireland Tax Treaty
The UK-Ireland double taxation agreement continues in force post-Brexit. Key provisions:
- Dividends: 5 percent for substantial holdings (10+ percent), 15 percent otherwise
- Interest: 0 percent
- Royalties: 0 percent
Dividends from an Irish-tax-resident company paid to a UK-resident shareholder face 5 or 15 percent Irish withholding, depending on whether Irish dividend withholding tax exemptions apply (and such exemptions often do for UK-resident recipients who submit proper documentation).
UK tax on received dividends from the Irish company applies to the British shareholder at their marginal rate with foreign tax credit for Irish withholding. UK residents with Irish companies should declare them on the self-assessment return.
The commercial logic for British founders forming Irish Ltds after Brexit is EU market access restoration. The 12.5 percent corporate tax is a real tax paid on real profits.
Founders who expect Ireland to function as a tax haven face disappointment and Revenue Commissioners scrutiny, founders who use Ireland for genuine EU-facing operations win on VAT simplicity, market access and long-term strategic positioning. The Irish Revenue Commissioners’ guidance on corporation tax residency covers the substance requirements.
One of the least appreciated operational impacts of Brexit is the loss of UK VAT MOSS rights. Digital product and SaaS firms based in the UK that serve EU B2C customers often find the Irish Ltd structure to be the lowest-friction solution.
Attempts by founders to run UK-only operations and register VAT separately in each EU country where customers reside typically hit an manageability wall at larger scales.
Banking Reality for British-Owned Irish Companies
Consolidation in Irish banking following Ulster Bank’s retreat has left AIB, Bank of Ireland and PTSB as the primary pillar banks. Fintech platforms like Revolut Business, Wise Business, Fire and Bunq work well for companies owned by Britons operating in Ireland. Main pillar banks need 2 to 6 weeks to open a business account and usually require an in-person visit.
Fintech account onboarding takes 1 to 2 weeks remotely.
| Bank | Onboarding Time | Notes |
|---|---|---|
| AIB | 2 to 6 weeks | In-person preferred |
| Bank of Ireland | 2 to 6 weeks | In-person preferred |
| PTSB | 3 to 8 weeks | More selective |
| Revolut Business | 1 to 2 weeks | Remote |
| Wise Business | 1 to 2 weeks | Remote |
| Fire.com | 1 to 2 weeks | Remote |
| Bunq | 1 to 2 weeks | Remote, EU |
Corporate Tax, VAT, OSS/IOSS
Corporation Tax: 12.5 percent trading. File Form CT1 with Revenue Commissioners annually, 9 months after accounting period end.
VAT: 23 percent standard rate. Mandatory registration above 42,500 EUR services turnover or 85,000 EUR goods turnover (raised from 40,000/80,000 EUR effective January 2025). For EU B2C sales, Ireland provides access to One Stop Shop (OSS) for EU distance selling and Import One Stop Shop (IOSS) for low-value imports, which simplifies multi-country VAT accounting substantially.
Ireland continues to function for British founders as a way to access OSS/IOSS while maintaining the same EU VAT framework lost to Brexit. VAT accounting does not split across multiple EU member states.
| Tax Item | Rate |
|---|---|
| Corporation Tax (trading) | 12.5 percent |
| Corporation Tax (passive) | 25 percent |
| Pillar Two (750M+ EUR revenue groups) | 15 percent |
| Knowledge Development Box (qualifying IP) | 10 percent |
| VAT standard | 23 percent |
| VAT reduced | 13.5 or 9 percent |
| Capital gains (individuals) | 33 percent |
| Dividend withholding | 25 percent (often exempted) |
Costs in EUR and GBP
| Item | Year 1 EUR | Year 1 GBP |
|---|---|---|
| CRO filing fee | 50 | 42 |
| Constitution preparation | 100 to 500 | 85 to 425 |
| Registered office | 200 to 800 | 170 to 680 |
| Section 137 bond (if used) | 1,500 to 2,500 | 1,275 to 2,125 |
| Company secretary | 400 to 1,000 | 340 to 850 |
| Accounting (annual) | 2,000 to 6,000 | 1,700 to 5,100 |
| Bank setup | 0 to 200 | 0 to 170 |
| VAT registration | 0 to 300 | 0 to 255 |
Year 1 total (with Section 137 bond): 4,250 to 11,350 EUR (3,612 to 9,648 GBP). Year 2 steady state: 3,500 to 8,000 EUR.
British Founder Operating Patterns
Many British founders run an Irish subsidiary of a UK limited company, with the UK Ltd as the parent holding and the Irish Ltd as the EU-facing operating entity. UK sales invoice from UK Ltd, EU sales invoice from Irish Ltd. Intercompany service agreements coordinate.
Other British founders relocate entirely to Ireland under the CTA, closing or scaling down the UK company and operating solely through Ireland with better 12.5 percent corporate tax treatment and EU market access.
Common Mistakes
Five patterns recur. First, forming the Irish company without understanding the EEA director requirement and facing Section 137 bond surprise at filing. Second, underestimating Irish accounting costs (the Irish jurisdiction is process-heavy relative to UK Ltd). Third, not coordinating Irish VAT with UK VAT on intra-company and inter-company transactions.
Fourth, assuming Ulster Bank would continue to serve the account when its business banking withdrawal was announced. Fifth, running the Irish Ltd as a pure paper company with no substance, then facing Revenue Commissioners’ scrutiny on tax residency.
When to Add or Simplify Structures
Some British founders expanding their Irish operations choose to consolidate fully into Ireland by closing the UK parent company. Others keep both structures to target specific UK and EU activities. The UK vs Ireland post-Brexit company formation comparison outlines the decision
Timeline
- Weeks 1 to 2 focus on planning the structure and preparing documentation.
- Weeks 2 through 4 focus on CRO filing and registration.
- Week 3 to 6: Revenue Commissioners registration, VAT if applicable
- Weeks 4 through 8 focus on setting up the bank account.
- Week 6 to 10: Operational
Northern Ireland and the Windsor Framework
Northern Ireland-based founders from the UK occupy a distinctive place after Brexit due to the Windsor Framework, which replaced the original Northern Ireland Protocol in 2023 and keeps Northern Ireland aligned with EU single market rules for goods.
The Good Friday Agreement grants Northern Irish citizens birthright citizenship in both Ireland and the UK, meaning Northern Irish entrepreneurs can hold Irish passports and maintain uninterrupted EU citizenship status.
Northern Ireland-based British founders commonly establish an Irish limited company as the natural step for cross-border expansion before Brexit friction sets in. The Windsor Framework’s provisions on goods will influence decision-making for founders shipping physical products, yet services-focused Northern Irish founders experience little change in how they form their Irish Ltd.
Irish Revenue Tax Residency Test
An Irish limited company is Irish tax resident if it is managed and controlled from Ireland, or under the post-2015 rules if it is incorporated in Ireland (with certain transition exceptions).
This is important for British founders using an Irish Ltd as an EU-facing subsidiary while themselves remaining UK-resident: the Irish company’s tax residency depends on where strategic decisions are made, not just where it is incorporated.
Practical substance building for Irish tax residency includes:
- Board meetings physically held in Ireland (or by video link with Irish-based participants)
- Irish-resident directors participating in strategic decision-making
- Many banking operations and headquarters are based in Ireland.
- Key contracts signed by Irish-resident signatories
Irish Ltds functioning as genuine operating entities with decision-making based in Britain typically satisfy these criteria for British founders. When British founders treat Irish Ltds as paper companies with all operational decisions made in London, they encounter tax residency challenges and risk CT1 treatment as UK-resident despite the firm’s Irish incorporation.
Brexit Impact on UK VAT MOSS and the Irish Solution
Before Brexit, UK companies used the UK’s VAT Mini One Stop Shop (MOSS) to account for EU B2C digital services VAT across all EU member states through a single UK registration.
Brexit ended UK access to EU VAT MOSS, forcing UK companies to either (a) register for VAT in a specific EU member state and use that state’s OSS/IOSS for EU-wide coverage, or (b) register separately in each EU country where they have B2C digital services revenue.
An Irish limited company with Irish VAT registration can use Ireland’s OSS/IOSS to serve the entire EU B2C market through a single VAT accounting point, restoring the simplicity that was lost with Brexit. This is one of the most concrete operational reasons British digital-product, content and SaaS founders form Irish subsidiaries specifically.
Dual Structure: UK Ltd with Irish Subsidiary
Many British founders operate both a UK Ltd and an Irish Ltd, with the UK Ltd as parent holding entity serving UK customers and the Irish Ltd as EU-facing operating subsidiary. Revenue, contracts and operational responsibilities split based on customer geography:
- UK customers: invoices come from UK Ltd and UK VAT applies.
- EU customers: invoiced from Irish Ltd, Irish VAT via OSS applies
- For non-EU, non-UK customers, invoices usually come from whatever entity maintains the relationship.
These elements - intercompany service agreements, transfer pricing documentation and consolidated group accounting - link the arrangement together. The design maintains UK customer familiarity while providing Irish EU access. For British founders with footprints in both markets, it often represents the clearest commercial structure.
How to start a new business in USA from Ireland post-Brexit?
Starting a new US business from Ireland post-Brexit is largely unaffected since Ireland-US relations and tax treaty remain intact. Irish citizens can form US LLC (Delaware $110 + $300/year, Wyoming $100 + $60/year) or C-Corp ($109 + $450/year minimum franchise) without US visit, SSN, or visa. EIN free from IRS (4 to 8 weeks by fax for Irish founders without SSN).
Banking at Mercury or Relay remote (5 to 10 days, free). For British citizens relocating to Ireland post-Brexit (Ireland remained in EU, UK left), Ireland offers continued EU market access and English-language environment. Irish company formation via CRO (Companies Registration Office) costs EUR 100 to 200 with EUR 1 minimum capital and 5 to 10 days processing.
Irish Limited Company pairs well with US LLC: Irish Ltd for EU operations (12.5% corporate tax), US LLC for US customer access. Ireland-US tax treaty prevents double taxation. US E-2 Investor Visa accessible to Irish citizens (Ireland is E-2 treaty country) for $100K+ investment + active management.
L-1 Intracompany Transferee visa for Irish Ltd owners transferring to US subsidiary after 1+ year Irish Ltd operation. For British citizens now holding Irish citizenship through family connections or residency-based naturalization, E-2 treaty country access is restored (UK lost E-1/E-2 access post-Brexit for commonwealth).
For British citizens without Irish citizenship, US E-2 remains unavailable - alternative routes: O-1 Extraordinary Ability, L-1 Intracompany Transfer, or EB-5 Investor Visa ($800K to $1.05M + 10 US jobs).
How to start a business in USA for non-citizens from Ireland post-Brexit?
Non-US-citizens start US businesses without needing visas or US residency for entity ownership.
For Irish citizens or British citizens relocated to Ireland post-Brexit, the standard setup is:
- Delaware LLC ($110 + $300/year)
- Wyoming LLC ($100 + $60/year)
- or Delaware C-Corp ($109 + $450/year minimum franchise) formation online
- free EIN from IRS (4 to 8 weeks by fax for non-residents without SSN)
- Mercury or Relay bank account (remote, 5 to 10 days, free)
- Stripe for payment processing (1 to 4 weeks approval)
Total setup $500 to $1,500 self-directed or $500 flat via Stripe Atlas. Ireland-US tax treaty prevents double taxation on US-sourced income (dividends 15%, interest 0%, royalties 0% withholding after treaty).
US E-2 Investor Visa accessible to Irish citizens (Ireland is E-2 treaty country) for $100K+ active US business investment - 2-year visa renewable indefinitely, does not lead to green card directly. L-1 Intracompany Transferee for Irish Ltd owners transferring to US subsidiary after 1+ year prior employment.
EB-5 Investor Visa requires $800K to $1.05M US investment + 10 US jobs, leads to conditional green card within 2 to 5 years. For British citizens post-Brexit without Irish citizenship, US E-2 is unavailable (UK lost E-1/E-2 access post-Brexit).
Irish Ltd + US LLC is an effective dual structure: Irish Ltd (EUR 100 to 200 formation + 12.5% corporate tax) for EU operations, US LLC ($100 to $300 formation + 21% federal + state tax) for US customer access.
How to start an e-commerce business in USA for Irish founders post-Brexit?
Irish founders starting US e-commerce businesses form Delaware LLC ($110 + $300/year) or Wyoming LLC ($100 + $60/year) remotely, obtain free EIN from IRS (4 to 8 weeks by fax for Irish founders without SSN), and open US business bank account at Mercury or Relay (remote, 5 to 10 days, free).
Post-Brexit, Ireland remained in the EU while UK left, creating new dynamics: Irish Ltd retains EU single market access for EU customer distribution, while UK Ltd lost EU VAT reverse charge mechanism for UK-to-EU B2B sales.
For e-commerce founders targeting US customers, the typical cross-border setup is: Irish Ltd (EUR 100 to 200 CRO + 12.5% corporate tax) or UK Ltd (£100 Companies House + 19% to 25% corporation tax) for EU/UK operations, plus US LLC ($100 to $300 + 21% federal + state tax) for US customer-facing Amazon, Shopify and Stripe operations. Ireland-US tax treaty prevents double taxation.
UK-US tax treaty prevents double taxation. Post-Brexit trade: UK-EU trade subject to customs declarations, rules of origin and potential tariffs on non-origin goods, Ireland-EU trade unaffected. US sales tax nexus: $100K sales or 200 transactions per state thresholds post-Wayfair 2018. Marketplace facilitator laws (Amazon, eBay, Etsy) handle US sales tax collection in 45+ states.
Direct Shopify sellers need TaxJar, Avalara, or Anrok automation. Irish founders frequently form US LLC + UK Ltd dual structure for maximum market access across US + EU + UK.
