DUBLIN — Cut Ireland’s minimum wage? Check. Collect more in property taxes from beleaguered homeowners? Check. Raise the corporate tax rate, which could plug the gaping hole in Ireland’s tattered balance sheets even faster? Well, no.

The austerity plan Ireland unveiled on Wednesday to secure a bailout from its international partners makes one thing clear: much of the 15 billion euros (or $20 billion) in savings the government has pledged to find over the next four years will come from the welfare state and the working class. But the measures will not touch large businesses like Microsoft, Intel and Pfizer, which have created thousands of jobs and fueled exports in Ireland for years, thanks to one of the lowest corporate tax rates in Europe.

Germany, France and other European countries have long complained that Ireland’s tax structure has distorted competition. Some politicians have seized on the troubles by pushing for an increase in the 12.5 percent rate as part of a rescue package of about 85 billion euros (or $114 billion), the terms of which are still being negotiated.

Some of that external pressure subsided this week as the political crisis in Ireland worsened. But if Ireland cannot meet its budget-cutting targets, or if its troubled banks require even more financing than expected, some countries might push the issue back into the spotlight.
