Indiana's state government collected $87 million less than expected in tax revenue during April.
That report released Thursday of the came less than a week after state legislators approved a new two-year state budget that was based on a more-optimistic forecast of tax revenue.
Gov. Mitch Daniels attributed the nearly 6 percent shortfall to what he called one-time factors. He says legislators made a wise decision in not including more of the expected $644 million revenue bump in the state spending plan.
Daniels says he continues to see some clouds over the national economy and that forecasting state revenues has proven tricky.
Some of the shortfall from the forecast came from a 13 percent decline in casino revenue from April 2010, partly because flooding closed one riverboat for several days.
