The Enterprise Minister Richard Bruton says anyone found to be evading tax will be prosecuted.
Mr Bruton was speaking after it emerged more than 300 companies in Ireland are mentioned in the the biggest ever leak of financial information.
The details from a law firm in Panama have exposed the offshore holdings of some of the world's most prominent politicians, celebrities and sport stars, including the Russian President Vladmir Putin and FIFA's ethics committee.
The papers also link a company registered on Botanic Avenue in Drumcondra in Dublin to international arms deals.
Minister Bruton, says if there is any evidence of wrongdoing, it will will be dealt with.
He said: "Well these are clearly concerns and as you know the government have been very active in developing through the so-called BEPS process through the OECD.
"Obviously if there are offences of Irish law discovered in this, you can be absolutely sure they will be vigorously prosecuted - but at this point we don't know that."
