The Taoiseach said he does not expect his former Environment Minister to draw any pensions from the Irish taxpayer while working as European Commissioner.
Enda Kenny nominated Phil Hogan to be Ireland's next Commissioner in Brussels later this year.
He will have a basic salary of just under €239,000 a year.
When asked about the Irish government pension, the Taoiseach said it shouldn't come into play, "assuming that he is appointed as a European commissioner."
