Top Democrats in the Kansas Legislature are criticizing what they describe as “gridlock” among Republicans on tax issues and suggest administrative problems could result.

Senate Minority Leader Anthony Hensley of Topeka and House Minority Leader Paul Davis of Lawrence said Wednesday that the Legislature’s research staff sees potential complications if the 2013 session drags into June.

Republican legislators can’t agree on adjusting the state sales tax to raise new revenues and prevent budget shortfalls while Kansas cuts income taxes. The sales tax is 6.3 percent but is scheduled by law to drop to 5.7 percent in July.

Hensley and Davis noted that the state is required by law to give retailers a month’s notice of a sales tax change before collecting the new levy.
