At an event to mark Ireland's formal exit from the European Union and International Monetary Fund bailout, Mr Noonan heaped praise on the Irish public for stoically enduring 28 billion euros ($38.46 billion) in spending cuts and tax hikes – equivalent to 20 percent of the value of the Irish economy – following its financial crash.

ECB warns growth and inflation to stay low
"The real heroes and heroines of the story are Irish people, who've had their taxes increased, they've had their services cut drastically – some of them, particularly public servants, have had very serious pay cuts," said Mr Noonan as he signalled that tax cuts were likely next year.
Dublin wants to cut income tax rates to stimulate economic growth and job creation. It follows warnings from Ireland's state investment agency, IDA Ireland, that high levels of personal taxation are threatening future foreign investment- a key sector of the economy.
Ireland's marginal income tax rate has increased sharply from 43.5 percent in 2008 to 52 percent for salaried workers now, which is the 10th highest of 34 OECD countries, according to the Irish Tax Institute.
But proposing income tax cuts even before it formally exits the bailout could raise concerns among Ireland's international lenders, which have provided 67.5 billion euros in loans to keep Dublin afloat since its banks collapsed in 2008-9.

Ireland's economic recovery remains fragile with a budget deficit of 7.5 percent of gross domestic product, growth forecast at 2 percent next year and public debt forecast to peak at a dangerously high level of 124 percent of GDP in 2014.
The Irish Fiscal Advisory Council, a budget watchdog set up after the financial crash, recently warned Dublin there is no room for income tax cuts until after 2016.
But Mr Noonan brushed aside concerns that such cuts would amount to a return to the boom-bust policies that got Ireland into trouble. "We can't go mad again, even if we had the resources," he said.
Mr Noonan said there may be room to cut income tax without reducing the overall take by stimulating growth and jobs creation.
Doubts still remain over Europe's approach to the euro zone crisis in spite of Ireland's relative success. In the new year, Brussels will face a series of challenges that raises questions about whether Ireland is a harbinger or an exception to the rule.
