The Finance Bill passed through the Seanad on Wednesday evening, paving the way for the Taoiseach to call a general election.
Confirming the date of the poll, Mr Harris said: "I'm looking forward to the weeks ahead and asking the people of Ireland for a mandate.
Mr Harris said it was important to announce the election in a way “that was respectful to the budgetary process”.
“We wanted to get the Finance Bill passed, it’s important that we underpin the budget. We don’t want to be knocking on people’s doors until we have tax cuts actually passed into law."
"I think we’re now ready to put our case to the people and I very much look forward to putting my case to the people in the weeks ahead," he told RTÉ news.

Meanwhile, the Green Party are mulling over supports to allow for the establishment of a factory for the construction of modular buildings.
One TD said that doing so would allow for quicker building of new houses, while also reducing the carbon emitted on building sites across the country.
