Minister for Finance Michael Noonan is set to table plans for a 20% levy on income that overseas investors receive from Irish property funds.
This is seen as a mechanism to stop so-called 'Vulture Funds' using tax loopholes to minimise their tax payments.
The full Finance Bill will be published later today - it is expected to contain new measures to curb personal tax evasion through the use of offshore accounts.
Wide scale changes to the help to buy scheme are also expected to be announced today.
The deal to get first time buyers on the property ladder has been accused of potentially hiking house prices. Critics also say the scheme, which includes mortgages of up to €400,000, would encourage people to take on too much debt.
Among the changes will be a decrease in the value of homes covered.

He said that tightening of border controls will come with measures to support job creation and economic growth.

Eurozone finance ministers will meet in Frankfurt today, the European Central Bank (ECB) is expected to leave key rates unchanged, and to keep its cards close to its chest regarding the future of its quantitative easing programme beyond its original timeline which ends in March of next year.
Last month, the ECB created committees of eurozone central bankers to pool ideas as to how to extend or wind-down the bond buying scheme, which has struggled to stimulate economic activity across the bloc.
It is likely that key policy decisions will be held until the ministers meet again in December - while Mario Draghi will outline the ECB's commitment to continued stimulation measures.
