Tom Wolf, a former state revenue secretary and a Democratic candidate for Pennsylvania governor, says the so-called Delaware Loophole is still open, despite Republican claims that it's effectively closed.
Wolf told a Pennsylvania Press Club luncheon on Monday that companies still use the loophole to avoid state taxes.
Wolf didn't say how he'd close it if he's elected. But Democratic candidates see it as a way to generate money for their pet programs.
For instance, U.S. Rep. Allyson Schwartz's campaign says closing the loophole could help add $100 million to an existing rebate program for seniors who pay property taxes or rent.
Proponents of a bill that passed the Republican-controlled Legislature last summer say it gives the state more authority beginning in 2015 to stop tax avoidance strategies.
