Topeka ? Kansas has collected $6 million less in taxes this month than anticipated, and disappointing sales tax collections are a key reason.

The state Department of Revenue reported Friday that the state took in $536 million in taxes during May, when the official forecast predicted $542 million. The shortfall was 1.1 percent.

Since the fiscal year began in July 2014, state tax collections have fallen short of the official prediction of $5 billion by about $10 million, or 0.2 percent.

Sales tax collections in May were $175 million, or about $8 million less than expected. The shortfall was about 4.3 percent.

But personal income tax collections exceeded expectations by about $12 million for the month. They were $278 million, about 4.6 percent more than the predicted $266 million.
