New figures from the Kansas Department of Revenue show that Gov. Sam Brownback’s income tax plan would result in a tax increase on average for the state’s poorest households.

The figures show that taxpayers with adjusted gross incomes of $25,000 or less would see an average increase of $156. They would, as a class, pay $88 million more in individual income taxes than they do now.

The Associated Press obtained the figures Tuesday. They were developed by the department for a special group convened by the Senate to study tax issues.

Households and some businesses with adjusted gross incomes of more than $250,000 would see their taxes drop on average 18.5%, or by more than $5,200.

The plan cuts individual income tax rates, but it eliminates credits and deductions.
