Irish Subsidiary or Branch? A Guide for Foreign Companies

A foreign business entering Ireland usually considers two structures: incorporating an Irish subsidiary or registering an Irish branch of the existing overseas company. Both can create a formal Irish presence, employ people, sign contracts and require Irish tax registrations. They are not legally interchangeable.

An Irish subsidiary is a new Irish company with its own legal personality. The foreign parent owns shares in it. A branch is an Irish registration of the foreign company itself, so the parent remains the contracting legal entity and is directly exposed to the branch's obligations. The best choice depends on liability, tax, regulation, accounts, commercial plans and how much independence the Irish operation needs.

Subsidiary versus branch at a glance

Option one: form an Irish subsidiary

A subsidiary is normally incorporated as an Irish LTD. It becomes a body corporate from the date on its certificate of incorporation and is legally distinct from the foreign shareholder. The parent can own 100% of the shares, appoint the board and fund the company through equity, loans or a combination designed with tax and legal advice.

The subsidiary has its own Irish registered office, constitution, share register, directors, company secretary, CRO number and compliance calendar. It signs contracts, invoices customers and holds assets in its own name. This separation is often useful when the Irish operation will hire staff, take a local lease, deal with regulated customers or build a business that may later receive investment or be sold.

Requirements for a foreign-owned subsidiary

• A company name acceptable to the CRO.
• A physical registered office in Ireland.
• At least one director, with the EEA-resident director rule addressed.
• A company secretary; a sole director cannot also be the secretary.
• A constitution and Form A1 setting out the activity, officers and subscribers.
• The foreign parent's incorporation and ownership information for verification.
• Accurate records of the legal shareholder and ultimate beneficial owners.
• Post-incorporation RBO, tax, payroll and sector registrations where applicable.

If no subsidiary director is resident in the EEA, the company will generally need a prescribed Section 137 bond at incorporation unless another statutory route applies. The foreign parent's location does not remove this director requirement.

Option two: register an Irish branch

A branch is not a new Irish company. It is the Irish establishment of an eligible company incorporated outside the State. The CRO describes this as an external company registration. Under Part 21 of the Companies Act 2014, an eligible foreign company that establishes a branch in Ireland must register it with the CRO within 30 days of establishment.

The parent continues to own the business and is the legal person behind branch contracts and liabilities. This can suit a group that wants one legal entity across markets, but it also means a claim against the Irish branch can be a claim against the foreign company itself.

EEA and non-EEA branch forms

The registration form depends on where the foreign company is incorporated. An EEA company generally files Form F12. A non-EEA company generally files Form F13. The UK is treated as non-EEA for these purposes following Brexit.

The CRO's external company guidance lists supporting documents such as a certified copy of the company's constitutional instrument, certificate of incorporation, name-change certificates where relevant, latest accounting documents and certified English translations where documents are not in Irish or English. Authentication or legalisation requirements can depend on where and how documents were certified.

Liability and risk separation

A subsidiary's separate legal personality is often its clearest commercial advantage. In ordinary circumstances, the parent shareholder's exposure is separated from the subsidiary's liabilities. That protection is not absolute: parent guarantees, wrongful conduct, regulatory duties and particular contracts can still create direct exposure.

A branch offers no equivalent separation because it is part of the foreign company. The parent owns the assets, enters the obligations and bears branch liabilities. A group should review insurance, customer contracts, employment exposure and regulatory risk before deciding that the administrative simplicity of one entity outweighs the lack of legal separation.

Management and governance

A subsidiary needs an Irish-company governance structure. Its directors owe duties to the Irish subsidiary, even when they are also executives of the parent. Board decisions, conflicts, related-party arrangements, intercompany funding and distributions should be documented for the subsidiary itself.

A branch does not have its own board of directors. The foreign company's directors remain in control, while the Irish registration identifies people authorised to represent the company, accept service or ensure compliance. Changes to the branch, its address or responsible people can trigger CRO filings. The CRO's post-registration guidance explains Forms F2, F3, F4, F7 and F14 and the circumstances in which they are used.

Accounts and public filings

An Irish subsidiary prepares its own accounting records and financial statements under the rules applying to that company. It files annual returns with the CRO and may have to attach financial statements, subject to the law and any exemption genuinely available to it.

A branch can be required to file accounting documents relating to the foreign company. The exact position differs between EEA and non-EEA companies and can depend on the accounting and publication rules in the home jurisdiction. Groups that prefer not to place parent-company accounts on an Irish public register should examine this consequence before choosing a branch.

Tax: structure follows the real activity

The subsidiary and branch routes can both create Irish tax obligations, but the analysis is different. An Irish-incorporated subsidiary is generally deemed Irish tax resident unless a double taxation agreement treats it as resident elsewhere. It normally registers for Corporation Tax and may require VAT, PAYE, Relevant Contracts Tax or other registrations based on its activities.

A foreign company can be Irish tax resident if it is centrally managed and controlled in Ireland. Even where it remains resident abroad, operating through an Irish branch may create an Irish permanent establishment and an Irish charge on attributable profits. Intercompany pricing, interest, royalties, services and profit attribution need specialist review.

The 12.5% Irish Corporation Tax rate generally applies to qualifying trading income; it should not be used as a blanket forecast for every subsidiary or branch. Review Revenue's company residence rules and obtain cross-border advice before the first transaction.

VAT, payroll and employees

Neither incorporation nor branch registration automatically produces a VAT number. The Irish operation applies to Revenue when registration is required or when a voluntary application is appropriate, and Revenue may request contracts, invoices, bank details, premises information or evidence of Irish activity.

Hiring employees can trigger PAYE payroll registration, employment-law duties, workplace policies, pensions and social-insurance questions. Staff transferred from the parent may also create immigration, posted-worker or cross-border social-security issues. Decide the employing entity before offers and contracts are issued.

Commercial factors that often decide the choice

A subsidiary may fit better when:

• The group wants liability separated from the foreign parent.
• Irish customers expect to contract with an Irish company.
• The operation will employ a local team or lease substantial premises.
• The group may bring in investors, grant local equity or sell the Irish business.
• Local governance and standalone accounts support the operating model.

A branch may fit better when:

• The group deliberately wants the parent to remain the single contracting entity.
• The Irish activity is an extension of a closely integrated overseas operation.
• Local customers and regulators accept a foreign company operating through a branch.
• The parent understands the public filing and direct-liability consequences.
• Tax and regulatory advisers confirm that a branch matches the planned activity.

Documents a foreign parent should prepare

• Certificate of incorporation and any certificates recording name changes.
• Current constitution, articles, charter or equivalent constitutive document.
• Latest financial statements or accounting documents.
• Board approval for the Irish expansion and authority for the people signing filings.
• Group ownership chart showing ultimate beneficial owners.
• Identity and address evidence for directors, representatives and beneficial owners.
• Certified translations where source documents are not in Irish or English.
• Legalisation or authentication evidence where required.
• A business plan explaining Irish activity, staff, customers, premises and funding.

A practical decision process

1. Define the Irish operation. Identify contracts, employees, assets, premises and regulated activities.
2. Map legal exposure. Decide whether the parent is willing to be directly liable for Irish branch obligations.
3. Model tax in both countries. Compare residence, permanent establishment, profit attribution, withholding tax and transfer pricing.
4. Review accounts and disclosure. Confirm which parent or subsidiary documents will become public.
5. Check governance. Identify subsidiary directors and secretary, or the branch's authorised and compliance people.
6. Confirm regulation and customer expectations. Some licences, tenders, landlords or enterprise customers may favour one structure.
7. Prepare certified documents early. Overseas certification, translation and legalisation can determine the filing schedule.
8. Register before trading deadlines are missed. In particular, an established branch must be registered within the CRO's 30-day period.

Common mistakes in foreign-company expansion

• Calling an Irish sales activity a branch without checking whether a branch has legally been established.
• Assuming a branch limits the foreign parent's liability.
• Forming a subsidiary without resolving the EEA-resident director requirement.
• Leaving certified corporate documents and translations until the end.
• Treating CRO registration as automatic tax, VAT, payroll or regulatory approval.
• Using the 12.5% trading rate without analysing the actual income and substance.
• Failing to document intercompany services, loans, intellectual property or transfer pricing.
• Ignoring home-country reporting for the foreign parent and its owners.

Next step for a foreign company

StartCompany.ie provides formation support for Irish LTDs, including foreign-owned subsidiaries. Review the company formation packages and the non-resident director route if the proposed board has no EEA-resident director. A branch registration is a different external-company process; obtain Irish legal and tax advice on the subsidiary-versus-branch decision before committing the group to either structure.
