The Government's corporation tax strategy statement has been strongly endorsed by the OECD official in charge of global corporation tax.
The document defends the 12.5% tax rate and says Ireland acts within the rules of international taxation.
It was published along with the Budget on Tuesday.
The statement commits the Government to ending a tax loophole that has allowed a small number of companies, including Apple, to be tax resident nowhere.
Pascal Saint-Amans, the OECD Director of the Centre for Tax Policy and Administration, told an Irish Tax Institute today that he has no problem with Ireland having a 12.5% corporate tax rate.
He said Ireland was playing an active role in shaping the global agenda on corporate taxation.
Minister for Finance Michael Noonan has said the rate will stay.
However, he said the tax regime is going to change to protect the national reputation.
