Topeka ? Gov. Sam Brownback will be the keynote speaker at a fundraiser for a group that supports elimination of the state income tax, using tax credits to send children to private schools and a 401(k) plan for new state employees to replace the current pension system.

The annual dinner of the Kansas Policy Institute is scheduled for Sept. 20 at the Hyatt Regency in Wichita.

Brownback’s speech topic is “Creating Jobs Through Fundamental Tax Reform.” KPI said he will discuss his goal of eliminating the state income tax.

Tickets to the event are $3,000 for a “personal freedom sponsor,” which includes a reception, dinner, a copy of “Rich States, Poor States” with a foreword written by Brownback, and top listing in the program; $2,000 for a “free market sponsor,” which includes the same features except prominent listing in the program.

A “limited government sponsorship” includes reception and dinner and listing in the program, and individual tickets for a general reception and dinner are $85 each.

KPI describes itself as “an independent think tank that advocates for free market solutions and the protection of personal freedom for all Kansans.”

Dave Trabert, the group’s president, has frequently appeared before legislative committees to testify.

Trabert said elimination of the state personal income tax and reducing the corporate income tax would spur economic growth in the state. He said the proposal will be one of the major issues of the 2012 legislative session that starts in January.

Brownback has said he wants to eliminate the tax but has not proposed a specific plan.

Nick Jordan, Brownback’s revenue secretary, is working on a proposal to present to the governor prior to the legislative session.

At a summit on the service economy in Overland Park on Wednesday, Brownback said that making changes to the state’s tax code was critical.

“People act economically rational,” he said. “We’ve got to create a rationale for people to grow here and be here,” he said.

But he got some push back from several business leaders at the summit. Some said they feared reducing the income tax would put pressure to increase the state sales tax, while other said they feared it would reduce revenue available for public schools.
