Workers will also see reductions in taxes, while those on welfare will also see increases in weekly payments.

Both lower rates of USC are expected to be reduced, with the 5 per cent rate dropping by a quarter of a per cent, while the 2.5 per cent rate, paid on incomes of €12,200-€18,800, will fall by half a per cent.
In addition, the threshold at which people enter the higher, 40 per cent rate of income tax will rise from its current level of €33,800 by €750 for a single person to €34,550.
A package of increases in welfare payments was still being hammered out on Monday but is expected to include a €5-a-week increase on most welfare payments, though the rises will not kick in until the spring of 2018.
There will also be an increase, expected to be about €400 million, in capital expenditure on housing and an increase in funding for the Housing Assistance Payments (HAP), a social welfare support for people who have a long-term housing needs, is also expected.
To pay for all this, Mr Donohoe is expected to announce that the rate of commercial stamp duty will increase from two per cent to six per cent. This will raise more than €400 million and will be the main revenue-raising measure of the budget.
