Should I Register a Subsidiary or Branch in Ireland?

You’ve decided to expand into Ireland. The market opportunity is clear, the talent pool is deep, and the corporation tax rate is competitive. But now you’re stuck on a question that trips up nearly every foreign company entering the Irish market: should you register a subsidiary or a branch?

Get this wrong and you could face unnecessary tax exposure, compliance headaches, or a structure that actively limits your ability to win contracts. Get it right and you build a foundation that supports growth for years to come.

This guide breaks down everything you need to know. Liability, tax, cost, timelines, compliance, and the practical realities of doing business in Ireland through either structure.

What’s the difference between a subsidiary and a branch in Ireland?

The distinction is fundamental, and it affects everything from how you pay tax to how Irish customers perceive you.

A subsidiary is a separate legal entity incorporated in Ireland under the Companies Act 2014. It has its own directors, its own share capital, its own registered office, and its own obligations to the Companies Registration Office (CRO). The parent company owns it, typically through shareholding, but the subsidiary operates as an independent legal entity in its own right.

A branch, by contrast, is an extension of the parent company. It is not a separate legal entity. When you register a branch in Ireland, you are registering the foreign parent’s presence here, not creating a new Irish company. The branch trades under the parent’s name and legal identity.

How does that play out in practice? Here’s a quick comparison:

• Legal status: A subsidiary is a separate legal entity; a branch is an extension of the parent company.
• Liability: Subsidiary liability is ring-fenced to the Irish company. Branch liabilities flow back to the parent.
• Tax: A subsidiary pays Irish corporate tax on worldwide income. A branch pays Irish tax on Irish-source profits only.
• Compliance: A subsidiary files its own annual return and financial statements. A branch must file the parent company’s accounts with the CRO.
• Setup time: Subsidiary incorporation typically takes longer. Branch registration can be faster but requires certified parent company documents.
• Perception: Irish customers, banks, and partners often prefer dealing with a locally incorporated Irish company.

Both structures require registration with the CRO. Both are subject to Irish tax obligations on profits earned here. But the way Revenue, banks, and your future customers treat each structure differs significantly.

How does limited liability differ between a branch and subsidiary?

This is often the deciding factor. A subsidiary is an independent legal entity, which means its liabilities belong to it alone. If the subsidiary faces a claim, the parent company’s assets are generally protected. The parent’s exposure is limited to whatever share capital it has invested.

A branch offers no such protection. Because a branch is an extension of the parent company, any liabilities the branch incurs are liabilities of the parent. Full stop. There is no legal separation.

Think about the real-world scenarios. A customer dispute in Ireland. A commercial lease obligation. An employment claim from Irish staff. A regulatory fine. With a subsidiary, these stay within the Irish entity. With a branch, they reach the parent company directly, wherever it is headquartered.

For foreign companies with significant assets to protect, this distinction alone often pushes the decision toward establishing a subsidiary. The liability firewall is one of the most valuable features of subsidiary companies under Irish law.

CRO filing and registration requirements

Irish subsidiary incorporation

To set up a subsidiary in Ireland, you incorporate a new Irish company, most commonly a private company limited by shares (LTD). The incorporation process is handled through the Companies Registration Office.

Here’s what you need:

• Company name: Must be approved by the CRO. Check availability on the CRO website before applying.
• Registered office: A physical address in Ireland where official correspondence will be sent.
• Constitution: The company’s governing document, setting out its rules and regulations.
• Directors: At least one director. At least one director must be resident in the European Economic Area, or the company must hold a Section 137 bond.
• Company secretary: Required under Irish law. Can be a person or a body corporate.
• Share capital: No minimum for a LTD, but you will need to issue at least one share. The parent company typically holds all shares.
• Form A1: The company registration form submitted to the CRO along with the constitution and consent forms.

Once the subsidiary is incorporated, it receives a CRO number, and a certificate of incorporation is issued. The subsidiary must then register for tax with Revenue, including corporation tax, VAT, and employer taxes as applicable.

Ongoing obligations include filing an annual return with the CRO (within 56 days of the annual return date), preparing financial statements, and maintaining statutory registers. The company must also hold an AGM within 18 months of incorporation.

Irish branch registration

Establishing a branch office follows a different path. Foreign companies registering a branch in Ireland must file specific documents with the CRO under Part 21 of the Companies Act 2014. The branch is classified as an “external company.”

Registration requires:

• Form F12: The branch registration form.
• Certified copies of the parent company’s constitutional documents: Translated into English or Irish if necessary.
• Details of directors and secretary of the parent company.
• A registered address in Ireland for the branch.
• Details of at least one person resident in Ireland authorised to accept service of documents on behalf of the company.
• The parent company’s most recent financial statements.

Once registered with the Companies Registration Office, the branch receives its own CRO number. The branch must then register with Revenue for Irish tax obligations.

Ongoing, the branch must file the parent company’s accounts with the CRO annually. Any changes to the parent’s directors, constitution, or registered details must also be notified. This is worth noting: the parent company’s full financial statements become publicly available in Ireland once received by the Companies Registration office. Many foreign companies find this level of disclosure uncomfortable.

How long does setup take?

Timelines vary, but here are realistic expectations.

Subsidiary incorporation: The CRO typically processes standard company formation applications within 5 to 10 working days. Express options exist for faster turnaround. However, the full process, including gathering director details, drafting the constitution, and preparing all forms, usually takes 2 to 4 weeks from start to finish.

Branch registration: This can be quicker on the CRO side, but it depends entirely on how fast you can gather and certify the parent company’s documents. If the parent is in a jurisdiction where notarisation, apostille, or translation is required, expect 3 to 6 weeks.

Beyond the CRO registration itself, factor in these practical steps:

• Bank account opening: Irish banks have become significantly more cautious with onboarding. For either a branch or a subsidiary, expect 4 to 8 weeks for bank account approval. Subsidiaries often have an easier time here; banks prefer dealing with an Irish company.
• Revenue registration: Typically 1 to 2 weeks after company registration or branch registration.
• Payroll setup: If hiring Irish staff, you will need to register as an employer and set up PAYE. Allow 2 to 3 weeks.
• Commercial leases: Landlords strongly prefer contracting with an Irish subsidiary rather than a branch of a foreign entity.

If speed is critical, a branch can sometimes be operational faster. But for practical purposes like banking and contracting, a subsidiary often proves smoother.

Tax implications

Irish subsidiary taxation

An Irish subsidiary is subject to Irish corporation tax on its worldwide profits. The standard corporate tax rate is 12.5% on trading income, one of the most competitive rates in Europe. A higher rate of 25% applies to passive or non-trading income.

Key taxation considerations for subsidiary companies:

• Corporation tax: The subsidiary pays Irish corporation tax at 12.5% on trading profits. For companies within the scope of Pillar Two (global minimum tax), the effective rate may be 15%.
• Dividends: Dividends paid by an Irish subsidiary to a foreign parent may be subject to dividend withholding tax (currently 25%), though this is often reduced or eliminated under Ireland’s extensive network of double taxation agreements.
• Transfer pricing: Transactions between the subsidiary and its parent company must be conducted at arm’s length. Revenue scrutinises intercompany pricing arrangements closely.
• R&D tax credits: Irish subsidiaries may qualify for the 30% R&D tax credit, a significant incentive for innovation-led businesses.

The subsidiary’s Irish tax obligations are self-contained. It files its own corporation tax return, claims its own reliefs, and manages its own tax affairs independently of the parent.

Irish branch taxation

A branch is subject to Irish tax on profits attributable to its activities within Ireland. The same 12.5% corporate tax rate applies to trading profits earned through the branch.

However, the taxation picture for a branch is more nuanced:

• Permanent establishment (PE): A branch in Ireland creates a PE for the parent company. This triggers Irish tax obligations on profits attributable to that PE.
• Profit attribution: Determining which profits are “Irish-source” versus earned elsewhere can be complex, particularly for service businesses or those with sales in Ireland and internationally.
• Double taxation treaties: The parent company’s home jurisdiction and Ireland’s treaty network determine how profits are allocated and whether double taxation in Ireland is avoided.
• No withholding tax on profit repatriation: Unlike subsidiary dividends, profits transferred from a branch to the parent are not subject to Irish withholding tax. This can be a meaningful advantage.

The branch does not file a separate Irish corporation tax return in its own name. Instead, the foreign parent files an Irish tax return for its Irish branch activities. The branch is subject to Irish corporation tax on those attributed profits.

Ongoing accounting and compliance

Subsidiary compliance

Running an Irish subsidiary means meeting a full set of corporate governance and compliance obligations. This is the trade-off for limited liability and local credibility.

• Annual return: Filed with the CRO every year, along with financial statements. Late filing carries penalties and the loss of audit exemption.
• Financial statements: Must comply with Irish or international accounting standards. Small and micro companies may qualify for simplified reporting.
• Audit: Required unless the subsidiary qualifies for audit exemption (turnover under EUR 12 million, balance sheet under EUR 6 million, fewer than 50 employees). Many Irish subsidiaries of foreign parents do not qualify because group thresholds apply.
• Corporation tax return: Filed annually with Revenue (Form CT1).
• VAT returns: Bi-monthly or as agreed with Revenue.
• Payroll compliance: PAYE, PRSI, and USC obligations for Irish employees.
• Beneficial ownership register: Must be filed with the Register of Beneficial Ownership.

A subsidiary requires ongoing engagement with an accountant or accounting firm to stay compliant. The compliance calendar is busy, but it is manageable with the right support.

Branch compliance

Branch compliance is lighter in some respects but carries its own complications.

• Parent accounts filing: The branch must file the parent company’s financial statements with the CRO annually. These become public records in Ireland, which can be a concern for privately held foreign companies.
• Change notifications: Any changes to the parent’s directors, constitution, or registered details must be notified to the CRO.
• Local bookkeeping: The branch needs to maintain records of its Irish business activities for Revenue purposes.
• VAT: If the branch makes taxable supplies in Ireland, it must register for and file Irish VAT returns.
• Payroll: Same PAYE obligations as a subsidiary if the branch employs staff in Ireland.
• Irish tax return: The parent files an Irish tax return covering the branch’s activities.

The branch may appear simpler on paper, but the requirement to file parent company accounts publicly and coordinate tax filings across jurisdictions often creates more complexity than expected.

Can I register from abroad?

Yes. Both a branch and a subsidiary can be registered without you physically being in Ireland. This is common for foreign companies expanding their business to Ireland.

For a subsidiary, the key requirements are:

• At least one EEA-resident director (or a Section 137 bond if no EEA-resident director is available).
• A registered address in Ireland for official correspondence.
• A company secretary who can be based anywhere.
• All formation documents can be submitted electronically through the CRO’s CORE system.

For a branch, you need:

• A person resident in Ireland authorised to accept legal documents on the branch’s behalf.
• A registered address in Ireland.
• Certified and, where necessary, apostilled copies of the parent company’s constitutional and corporate documents.

The main challenge with remote setup is banking. Irish banks typically require in-person meetings or video verification for account opening, and the process is notoriously slow for companies outside of Ireland. A subsidiary with Irish directors generally has a smoother experience opening a bank account than a branch of an external company.

Many foreign companies use professional firms like Kinore to handle the entire registration process remotely, from company formation through to Revenue registration and bank introductions.

How much does it cost?

Costs depend on whether you choose a branch or subsidiary and how much professional support you need.

Upfront costs

• CRO filing fee (subsidiary): EUR 50 for standard incorporation; EUR 100 for express.
• CRO filing fee (branch): EUR 50 for branch registration.
• Professional fees (subsidiary): Typically EUR 1,500 to EUR 3,500 for company formation, including constitution drafting, registered office provision, and Revenue registration.
• Professional fees (branch): Typically EUR 1,000 to EUR 2,500, though document certification and translation can add significantly.
• Document certification/apostille: Varies by jurisdiction. Budget EUR 500 to EUR 1,500 for branch registration documents.
• Section 137 bond (if needed): Approximately EUR 1,500 to EUR 2,000 annually if no EEA-resident director is appointed for a subsidiary.

Ongoing costs

• Annual return filing (subsidiary): EUR 20 CRO fee, plus accountancy fees for preparing financial statements (EUR 2,000 to EUR 8,000+ depending on complexity).
• Annual accounts filing (branch): EUR 20 CRO fee, plus costs of translating and certifying parent accounts if needed.
• Statutory audit (subsidiary): EUR 3,000 to EUR 10,000+ if required.
• Ongoing accounting and tax compliance: EUR 3,000 to EUR 15,000 annually for either structure, depending on transaction volume.
• Registered office and company secretary services: EUR 500 to EUR 1,500 annually.

A subsidiary generally costs more upfront and ongoing. But the additional cost buys you limited liability, local credibility, and a cleaner structure for growth. For many businesses, the investment pays for itself quickly.

How do I decide?

Credibility, contracting, and control

If you plan to win Irish customers, hire Irish staff, or sign commercial leases, a subsidiary is almost always the better choice. Irish subsidiaries carry more credibility with banks, customers, and partners than a branch of a foreign entity. Many procurement processes, particularly in the public sector, favour or require a locally incorporated Irish company.

A subsidiary also gives you greater operational control. You appoint local directors who understand the Irish market. You build a business presence in Ireland that feels local, because it is.

Business type and growth plans

Consider what you are actually doing in Ireland. If you are setting up in Ireland for a specific, time-limited project, a branch may be the pragmatic choice. Establishing a branch makes sense for short-term operations or where the Irish activities are genuinely limited.

If you are building a long-term operation, hiring staff, and growing revenue, a subsidiary is the stronger foundation. Subsidiary companies can raise their own financing, enter contracts independently, and scale without constantly referring back to the parent company’s legal structure.

Opening a subsidiary in Ireland signals commitment. Opening a branch signals caution. Neither is inherently wrong, but your Irish stakeholders will read the signal.

Regulatory requirements by industry

Some sectors require specific structures. Financial services firms in Ireland may need to be authorised by the Central Bank, which typically requires a locally incorporated entity. Similarly, certain government contracts and regulated activities may only be open to an Irish company.

If your industry has specific regulatory requirements within Ireland, check these before deciding between a branch or subsidiary. The regulatory landscape can make the decision for you.

FAQs

Is a branch a separate legal entity?

No. A branch is an extension of the parent company. It is not a separate legal entity. The parent company bears full legal and financial responsibility for the branch’s activities. A subsidiary is a separate legal entity with its own rights and obligations.

Do I need Irish directors for a subsidiary?

You need at least one director who is resident in the EEA. If no EEA-resident director is available, the subsidiary requires a Section 137 bond (approximately EUR 1,500 to EUR 2,000 per year). For a branch, there is no director requirement, but you must appoint a person in Ireland to accept legal documents.

Will the CRO publish my details?

Yes. Both subsidiary and branch details are publicly available on the CRO register. For a subsidiary, this includes director details, registered office, and financial statements. For a branch, the parent company’s accounts are also published, registered with the Companies Registration office. This public disclosure of parent accounts is a significant consideration for privately held foreign companies.

Can I convert a branch to a subsidiary?

There is no direct conversion process. You would need to incorporate a new subsidiary, transfer the branch’s assets and contracts to the subsidiary, and then close the branch registration. This is common and straightforward with proper planning, but it does involve re-registering with Revenue and potentially re-negotiating contracts. Many businesses that start with a branch eventually make this transition as their Irish operations grow.

Which is more tax-efficient?

It depends on your specific circumstances. A branch avoids dividend withholding tax on profit repatriation, which can be advantageous. A subsidiary may offer better access to Irish tax incentives, R&D credits, and treaty benefits. The difference between a subsidiary and a branch from an Irish tax perspective often comes down to how profits are structured and repatriated. Professional tax advice is essential here.

Can I set up a branch and a subsidiary?

Yes. Some foreign companies register both a branch and subsidiary in Ireland for different business activities. This is less common but can make sense where distinct activities of the branch and the subsidiary serve different strategic purposes.

Which structure is faster to close if things don’t work out?

A branch is generally easier to wind down. You deregister with the CRO and Revenue. Closing a subsidiary requires a formal striking-off or liquidation process, which takes longer and costs more. If you are testing the Irish market and are unsure about long-term commitment, this is worth considering.
