International Tax Services Ireland
Cross-border tax obligations can affect how Irish businesses structure operations, report income and manage transactions with overseas entities. Finsoul Ireland provides international tax services for Irish companies, overseas businesses operating in Ireland, investors and individuals with cross-border tax matters. Our work considers the Irish tax position alongside relevant overseas requirements, so decisions can be assessed before transactions or structural changes take place.
Businesses may face tax questions when opening an overseas branch, establishing a subsidiary, receiving foreign income, making payments to non-Irish entities or moving staff across borders. We provide practical advice on these matters, supported by review of corporate structures, contracts, transactions and available tax records. Our international tax consultant can help identify the main tax considerations, required filings and areas that need specialist attention.
Strategic International Tax Support for Cross-Border Businesses
Cross-border activity can create obligations in more than one jurisdiction. The tax treatment of profits, financing, intellectual property, services, dividends and other payments depends on the facts of the arrangement and the rules that apply in each country. Irish businesses also need to consider applicable double taxation agreements and Irish transfer pricing requirements.
Finsoul Ireland reviews the commercial structure behind an international transaction rather than looking at tax in isolation. We consider the entities involved, the flow of income and expenditure, decision-making, contractual arrangements and the location of relevant activities. This gives management a clearer basis for assessing tax exposure, reporting requirements and the effect of proposed changes.
Who Needs International Tax Services?
Cross-border tax matters can arise at different stages of a business’s development. Our support is relevant to organisations and individuals with one or more international connections.
Irish Companies Expanding Overseas
Businesses entering another country may need to assess the tax position before establishing a branch, subsidiary, sales operation or local presence. We review the proposed structure and identify Irish and overseas tax matters for consideration.
Multinational Businesses Operating in Ireland
Groups with Irish entities may need support with corporate tax, intercompany transactions, withholding tax, VAT and reporting. We help coordinate the Irish aspects with information supplied by overseas advisers.
Businesses With Overseas Subsidiaries or Branches
An overseas entity can create additional filing, profit allocation and governance requirements. We review the relationship between the Irish business and its foreign operations and identify relevant tax obligations.
Companies Receiving Foreign Income
Interest, dividends, royalties and other overseas income may have Irish reporting and tax implications. We assess the income source and relevant reliefs or treaty provisions.
Businesses Involved in Cross-Border Transactions
Acquisitions, disposals, financing arrangements, service agreements and intercompany transactions can create tax consequences in several countries. We review the transaction structure and highlight issues requiring attention.
Investors With International Assets or Investments
Individuals and businesses holding overseas investments may need support with foreign income, tax credits, residency and reporting obligations. The appropriate treatment depends on the asset, jurisdiction and taxpayer circumstances.
Individuals With International Tax Obligations
People who live, work or invest across borders can face questions about residence, foreign income and treaty relief. An international tax accountant can review the available information and explain the Irish reporting position.
Our International Tax Services
Our work covers planning, corporate tax, treaty matters, transfer pricing and compliance. The scope can be agreed around a specific transaction or an ongoing requirement.
Cross-Border Tax Planning
We assess proposed international activities before implementation. This can include reviewing entity structures, financing arrangements, overseas expansion plans and cross-border contracts. The aim is to identify tax consequences early and give decision-makers clear information for commercial planning.
International Corporate Tax
Irish companies with overseas activities may need to consider how profits are taxed in different jurisdictions. Foreign companies operating in Ireland may also have Irish corporate tax obligations. We review the structure, activities and available records and coordinate with local advisers where local-law advice is required.
Double Taxation Relief
Ireland has Double Taxation Agreements with a range of countries. Depending on the circumstances, treaty provisions and foreign tax credits may reduce the effect of tax being charged in more than one jurisdiction. Revenue notes that relief can apply through a credit for qualifying foreign tax under an applicable agreement. We review the relevant income, residence position and treaty provisions before advising on available relief.
Transfer Pricing
Irish transfer pricing legislation is contained in Part 35A of the Taxes Consolidation Act 1997 and applies the arm’s length principle to relevant related-party transactions. Revenue states that the OECD transfer pricing guidelines inform the application of that principle in Ireland. We can review intercompany pricing, policies and supporting documentation and identify areas requiring further work. An international tax consultant can also support transfer pricing reviews where group transactions form a material part of the tax position.
International VAT
Cross-border supplies of goods and services can create VAT obligations in Ireland and other jurisdictions. We review the nature of the supply, customer or supplier location, transaction flows and available registrations. Support can include VAT registration considerations, reporting requirements and coordination with specialists where local rules apply.
Withholding Tax
Payments such as dividends, interest and royalties may be subject to withholding tax depending on the payer, recipient, jurisdiction and applicable treaty. We review payment arrangements and relevant documentation so businesses can assess the Irish position and identify where treaty relief may be available.
Permanent Establishment
An overseas branch, office, employee activity or other business presence can raise questions about permanent establishment. We assess the facts of the operation and identify issues that may require review under Irish law and the relevant tax treaty. Early assessment can help management consider the tax implications of an expansion plan.
International Tax Compliance
Cross-border structures often require accurate records and timely filings across several reporting systems. Our international tax compliance support can cover tax return information, foreign income reporting, supporting schedules, documentation and coordination of information required for filings. We can also help maintain a clear record of deadlines and responsibilities.
International Tax Advisory
Advisory work can support business expansion, restructuring, acquisitions, international investments and significant cross-border transactions. We assess the proposed activity, identify tax considerations and explain practical options. For complex matters, we work with legal, accounting and overseas tax specialists where their input is required.
International Tax Issues We Help Address
International tax problems often arise from changes in business structure, unclear ownership of activities or incomplete records. We help clients identify the specific issue, establish the relevant facts and determine the next steps.
Double taxation and relief claims
Foreign income reporting
Transfer pricing requirements
Withholding tax exposure
Permanent establishment risks
Cross-border VAT obligations

How Our International Tax Process Works
An international tax consultant uses a structured process so clients know what information is required, what is being reviewed, and what decisions need to be made. The level of work depends on the countries involved, transaction value, business structure and reporting requirements.
International Tax for Irish Businesses Expanding Overseas
Expansion into another country should be assessed from both a commercial and tax perspective. An Irish business may need to consider the proposed legal structure, overseas branch or subsidiary, local employees, cross-border sales, financing, contracts, intellectual property and reporting obligations. We review these factors with the information available and identify areas that require local-country advice before implementation.
International Tax for Foreign Businesses in Ireland
Foreign businesses entering Ireland need to establish their Irish tax obligations at an early stage. Depending on the business model, this can involve corporate tax, VAT, payroll-related matters, permanent establishment questions and withholding tax on cross-border payments. Our cross-border tax support helps foreign businesses organise the Irish side of their tax position and coordinate information with advisers in other jurisdictions.

Frequently Asked Questions
What are international tax services?
International tax services cover professional support for tax matters involving more than one country. They can include cross-border tax planning, corporate tax, treaty relief, transfer pricing, VAT, withholding tax, permanent establishment and reporting. The exact scope depends on the business structure, countries involved and type of transaction.
When does an Irish business need international tax advice?
An Irish business should consider advice when it plans overseas expansion, establishes a foreign subsidiary or branch, receives foreign income, enters significant cross-border transactions or changes its international group structure. Early review can help identify registration, reporting and tax issues before a transaction or expansion takes place.
What is double taxation relief?
Double taxation relief can reduce the effect of the same income being taxed in two countries where the relevant rules permit relief. Revenue’s guidance explains that qualifying taxpayers may be entitled to a credit for foreign tax under an applicable Double Taxation Agreement. The availability and amount of relief depend on the taxpayer’s circumstances and the relevant treaty.
What is transfer pricing?
Transfer pricing concerns the pricing of transactions between related parties, such as companies within the same group. Ireland applies the arm’s length principle to relevant transactions, meaning they are generally assessed as if they had taken place between independent parties. Revenue confirms that Ireland’s transfer pricing rules are set out in Part 35A of the Taxes Consolidation Act 1997.
Do Irish companies pay tax on foreign income?
The answer depends on the company’s circumstances, the nature of the income, residence position, source rules and any applicable relief or treaty provisions. A review of the specific income and structure is needed before determining the Irish tax treatment. An international tax accountant can assess the available information and identify the relevant reporting considerations.
