A review of the Wisconsin Economic Development Corporation finds the state agency is improving, but still lacking in some areas. The report from the Legislative Audit Bureau finds that the W-E-D-C mostly complied with state law during the last fiscal year. It apparently didn’t always award tax credits for wages paid as required by law. Auditors say it also sometimes waited more than a year to revoke credits for businesses that failed to live up to their contracts with the state. In the 10 years since the W-E-D-C was formed, only about one-third of businesses getting tax credit actually created the promised number of jobs.
