The Finance Bill to give legal effect to the measures contained in Budget 2012 will be published today.
More detail is expected on many of the measures in the Budget, including additional mortgage interest relief for people who bought their first home between 2004 and 2008.
Last December's Budget saw no increase in income tax, but did bring in changes to a range of other taxes including a 2% increase in VAT and increases in capital gains tax and DIRT.
Today's Finance Bill will give legal effect to those changes.
The Bill is also thought to include tax incentives to encourage overseas investors to start doing business in Ireland, and other tax reliefs to allow Irish companies to market their products abroad.
The Finance Minister Michael Noonan will outline the measures in the bill later today.
