Illinois and 25 other states, including the District of Columbia, do a poor job of tracking whether corporate tax breaks meant to spur job growth fulfill their purpose, according to a new report.

The study chided states for not giving lawmakers enough information on tax break legislation. The report found that only 13 states do an adequate job of tracking the breaks.

Even as it deals with a perpetual budget crisis, Illinois has dramatically increased the amount of tax breaks given to corporations -- from $63.7 million in 2006 to $272 million in 2010. That doesn't include the high-profile tax deals the state recently gave the financial exchanges and Sears Holding Corporation.
