International Business


We advise, guide and act on behalf of clients from all over the world in every aspect of international business development and investment: from initial investment or company purchase through to incorporation, local tax compliance and day-to-day bookkeeping 
and accounting.


As well as a wealth of expertise carrying out international transactions for clients at home and abroad, we also have access to an association of accounting firms all over the globe through our membership of AGN International.


AGN International represents over 200 independent accounting and consulting firms in nearly 100 countries. Duignan Carthy O’Neill is a prominent member of this association and thus has access to the font of local knowledge and contacts that are invaluable when conducting business abroad.  


We also have the technical expertise to take care of your overseas business: we adhere to international accounting standards such as IAS and IFRS, and we are registered with the Public Company Accounting Oversight Board.


Our specialist knowledge of international tax affairs ensures that clients get the best advice on how to maximise their overseas investments and how to repatriate and extract profits in the most tax-efficient manner.


We have expert knowledge in all compliance and tax planning matters, such as the implications of cross-border transactions, how to handle withholding tax and repatriation of profits, VAT planning and anti-avoidance legislation. Finally, we can advise on the efficient remuneration of globally mobile executives.

Are you an Irish firm expanding overseas? 

We have over 40 years’ experience helping Irish companies to set up operations overseas,
in Europe and beyond. Whether you’re looking to make an acquisition in a foreign territory, or to establish an overseas office for your expanding business, we can help you overcome language, cultural and bureaucratic barriers to make the process as seamless as possible.  


Are you a US, European or Asian multinational looking to set up an Irish base? 

We’ve helped dozens of companies establish themselves in Ireland - from a single office 
to a European headquarters.


We can take care of the entire process, providing you with a one-stop shop for the services that you need to start and run an Irish corporate, such as VAT registration, opening a bank account, financial administration, tax compliance and account auditing. We can advise on the most tax-efficient structure for operations, from both an Irish and foreign point of view. We also act as financial controller on behalf of many clients, and can provide company directors or company secretaries.


Are you a US or European company expanding into a new territory? 

Many of our multinational clients ask us to help with setting up subsidiaries or making acquisitions outside Ireland. We have in-depth knowledge of overseas markets, through first-hand experience and through our connections with international accounting association AGN International. We can manage everything on your behalf - from due diligence to corporate finance to tax compliance - and you only deal with the team here at Duignan Carthy O’Neill.
