Spending on new tax measures is to increase from €500 million to €1 billion in the Budget.
To tackle the cost of living crisis, Ministers are looking at another €200 energy credit payment to households, extending the fuel allowance and a Christmas bonus style payment - but in the autumn.
Junior Fianna Fáil Minister Robert Troy has said the summer economic statement shows that public finances are in a healthy position.
Speaking to RTÉ, he said there will be once-off supports that will help to mitigate against the most extreme elements of the cost-of-living increases announced in the Budget.
He said: "As part of the budget, there will be a comprehensive package of measures to help the people who need the help the most, the people who are finding it extraordinarily difficult, energy costs, the costs of living, and that will be done in parallel to this Budget later this year.”
Taoiseach Micheál Martin, Tanáiste Leo Vardkar and Green Party leader Eamon Ryan are meeting to sign off on the Summer Economic Statement before it goes to Cabinet later on Monday.
Mr Martin will speak to the media later on Monday and he will be joined by Finance Minister Paschal Donohoe.
