The Kansas Center for Economic Growth said the state should eliminate its tax cuts enacted in 2012 and 2013.
The group is blaming the cuts for an estimated $290 million hole in the state budget.
Brownback’s spokeswoman said reversing an income tax break for business owners would not help Kansas maintain a pro-growth environment.
Brownback gave lawmakers alternative options to address the deficit, including cuts to higher education, early childhood programs and the state DOT.
State lawmakers came back to work from a month-long break on Wednesday to begin tackling the budget and other issues. They are meeting today to discuss further action.
