The Fine Gael Leader has told his parliamentary party meeting that now is the right time to make decisions on the local property tax.
It follows agreement by Cabinet yesterday that owners of new homes built since 2013 will now have to pay Local Property Tax.
Referencing the Dublin Bay South constituency where there is an upcoming by-election, Leo Varadkar said some homes there will pay less under the changes.
He said a home in Ranelagh with a value of over €617,000 today could see its property tax bill fall.
He said this would also be the case for a property previously valued €1.3 million but now worth €1.6m.
While a home in Irishtown previously valued at €260,000 and now worth €445,000 would continue to pay the same amount of property tax, he said.
He said the constituency was not exceptional and across the country most homeowners would pay the same or less in property tax.
At the Fianna Fáil party meeting, Taoiseach Micheál Martin said that a "Housing for All" policy will be published in the coming weeks.
He said more homes and housing are needed to anchor and build communities.
There was also agreement at the meeting that better facilities are needed to allow people meet outdoors this summer.
The party said Government would work will councils to look at things like street "redesigns" for this purpose.
