Topeka ? A state senator from Sedgwick County is proposing that Kansas lawmakers roll back a 1-cent increase in the state sales tax six months before it’s due to expire.

Republican Sen. Carolyn McGinn says Monday that rolling back the tax early will keep the state’s promise to taxpayers without causing problems for state programs.

The three-year increase was approved in 2010 as state revenues plummeted and budgets were tightened.

With the economy rebounding sooner than predicted, the Senate Ways and Means Committee chairwoman wants the 1-cent hike to expire on Dec. 31, 2012, instead of July 1, 2013.

McGinn says a portion of the tax dedicated to highway projects would remain in place. She also says she hasn’t spoken about her proposal with Gov. Sam Brownback, who’s preparing his own tax plan.
