Kansas says its tax collections in August fell $10 million short of expectations and Republican Gov. Sam Brownback blames a soft economy.

The state Department of Revenue report Thursday marked the fourth consecutive month that Kansas has failed to hit its revenue projections. Tax collections have fallen short 10 of the past 12 months.

The state collected $427 million in taxes last month. A fiscal forecast made in April predicted the state would take in more than $437 million. The shortfall is 2.3 percent.

Kansas has struggled to balance its budget after GOP lawmakers heeded Brownback’s call to slash personal income taxes in 2012 and 2013 as an economic stimulus.

But Brownback said this week that slumps in agriculture and energy production are to blame for disappointing revenues.
