Labour has asked for more details on how much money Fine Gael and Fianna Fáil want to borrow in the coming years.
The party's new leader Alan Kelly has replied to the request from the two larger parties to enter government talks with five questions.
He also set out 21 core policies Labour sees as crucial for the next government.
They include a national living wage, the ending of the two tier healthcare system and halving Ireland's climate emissions by 2030.

In his letter, Deputy Kelly asks for details on proposed taxation measures and spending cuts.
He also asks for clarity on plans for public sector pay deals and whether the COVID-19 unemployment payment will continue at the current rate beyond the immediate crisis.
Labour TD Duncan Smith says they are not planning to enter government, but want more details of the plans from Leo Varadkar and Micheál Martin:
He explained: "We want detail in relation to how much the country is going to have to borrow over the next three years.
"We want some detail in relation to how the COVID-19 unemployment payment will be extended for those who can't find work."
Deputy Smith said the document sent by the two large parties was 'vague' and 'wishy-washy', so his party now wants firm details on their economic plan for the coming years.
Meanwhile, Fine Gael and Fianna Fáil are continuing to prepare a response to the Green Party on entering government together.
The Greens sent Leo Varadkar and Micheál Martin a 17 point letter last week setting out their baseline demands and concerns.
