Negotiators from the Kansas House and Senate report little progress in working out differences in plans for further cuts in personal income taxes.
Key legislators said Monday the main sticking point is whether to let a 2010 increase in the state sales tax expire in July as scheduled.
The Senate is backing Gov. Sam Brownback's proposal to keep the sales tax at 6.3 percent to shore up the state budget in future years. The House has voted to let it drop back to 5.7 percent as required by current law.
The rest of the legislation would make changes in income tax deductions and exemptions in efforts to raise additional revenue.
Negotiators are scheduled to resume their talks Tuesday.
