Not that foreign firms will necessarily be dying to leave. Noonan is keeping Ireland's lower-than-average 12.5 percent corporate tax, and there will be big tax breaks for companies that conduct research and development on its soil. In essence, the minister is trying to strike a very careful balance. He wants to appease European Union investigators who say that Apple and its peers are flouting the law, but he also doesn't want to raise taxes so much that these companies bolt toward other nations that offer considerably better deals. However well this strategy works, it's safe to say that the move won't have American companies repatriating their cash any time soon.
