The Finance Bill has passed all stages in the Dáil and will now move to the Seanad for consideration before being sent to President Michael D Higgins for signature.
Over an extensive debate lasting four hours, the Bill passed by a margin of 80 votes to 53 late last night.
The Bill, once enacted, will give legal effect to the tax measures outlined in Budget 2024.
Measures include reductions in income tax and the Universal Social Charge, an increase in the rent tax credit to €750 and the establishment of the new mortgage interest relief.
The Finance Bill also contains extensive enterprise supports including a new measure to incentivise what is known as angel investment in small innovative start-ups.
The Bill includes the implementation of Pillar II of the OECD agreement reached back in 2021.
Under the changes, companies with global revenues in excess of €750 million will be subject to a minimum corporation tax rate of 15%.
Minister for Finance Michael McGrath said: "The Bill once enacted will provide real and tangible benefits to people and families struggling with the cost of living.
"The Bill also provides for a once in a generation reform of our corporate tax system in line with the international agreement we signed up to in 2021."
