Idaho's state tax revenues for May came in $3.4 million below forecast, but with just one month left to go in the fiscal year, year-to-date collections are still $33.7 million ahead of forecast. Individual income taxes were well below forecasts, but that was due to bigger than expected refund payments, and the state's Division of Financial Management said it reflects changes in historical refund patterns that have shown up throughout the year. Much of the drop in individual income tax revenue for the month was offset by a big national mortgage settlement that brought the state $13.3 million.
