A panel of lawmakers met this week to review the dozens of state tax credits that are available. Republican Representative Pat Grassley of New Hartford, a member of the committee, is also Speaker-Select of the Iowa House. He says some credits are decades old and it’s hard to know how they’ll impact the budget from year to year.

Grassley cautions that any changes to tax credits will be hard to pass because he expects strong opposition from interest groups. The State of Iowa paid out more than 200 million dollars in tax credits during the last state fiscal year.
