TOPEKA, Kan. (AP) -- Researchers for the Kansas Legislature are projecting that Gov. Sam Brownback's plan for more income tax cuts would create a $782 million budget shortfall in July 2018.

But proponents of additional cuts are questioning whether the report Thursday from the nonpartisan Kansas Legislative Research Department is too pessimistic.

Brownback wants to follow up on aggressive individual income tax cuts enacted last year with a fresh round of rate cuts over three years. He's proposing to stabilize the budget by eliminating two popular income tax deductions for homeowners and raising additional sales tax revenues.

Critics were quick to see the numbers as evidence that Brownback's plan is reckless.

But Revenue Secretary Nick Jordan said the researchers don't account for how further cuts will stimulate economic activity.
