Some €14,000 had been spent this year up to the end of June
The Department of the Taoiseach has spent nearly €75,000 on taxis since 2015.
Some €14,000 had been spent by the department this year up to the end of June.
An average of almost €30,000 a year was spent in 2015 and 2016.
While almost €130,000 has been spent over the past three years on ground transport during foreign trips taken by Enda Kenny, Leo Varadkar or Ministers of State.
The figures were submitted following a parliamentary question from Deputy Catherine Murphy.
In response, Mr Varadkar said: "My department has a taxi account for official business purposes with a company selected by the Office of Government Procurement following a public tender.
"Taxis are used for official purposes where there is no other practical or suitable alternative mode of transport available."
On top of taxi fares, €1,800 was spent in 2015 on domestic car hire to transport relatives to the State funeral for Thomas Kent.
