The Finance Bill is to be published tomorrow including details of the €200 parking levy and a possible change to the airport tax.
The Government's new €200 workplace parking levy is to be introduced in five cities from next January.
Minister for Finance Brian Lenihan announced the levy on Budget day last month.
The details of the levy will be published in tomorrow's Finance Bill but it will apply in Dublin, Cork, Limerick, Galway and Waterford.
It will cover more than 50,000 car park spaces in the private and public sectors.
There will be special concessions for part-time workers and shift workers, while drivers with disabilities will be exempt from the measure.
Employees who share car parking spaces will be subject to a reduced levy.
The fee will have to be collected by employers in the five cities through payroll deductions.
Meanwhile, there are indications that the Government is to make changes to the airport departure tax that it included in the Budget.
It had originally planned to introduce a €10 fee for passengers flying out of Ireland on journeys greater than 300km.
A lower rate of €2 was to apply for shorter trips.
However, airports along the western seaboard complained that their passengers will be particularly affected by the new charge.
It is now thought that reforms will be made to the plan to make it more equitable.
It is believed the way the fee is to be calculated will change.
The full details will be revealed in tomorrow's Finance Bill.
