Two Michigan lawmakers want to provide free public university tuition for Michigan's high school graduates by raising the state income tax to create reimbursable tax credits.
The proposal to be detailed Tuesday also would provide money to boost Michigan's preschool programs.
The proposal would cost a household earning $50,000 a year more than $500 in additional annual income taxes before deductions.
Rep. Alma Wheeler Smith of Washtenaw County's Salem Township and Rep. Rebekah Warren of Ann Arbor are scheduled to detail the proposal at the state Capitol. Both are Democrats.
The lawmakers want the Legislature to put the proposal before state voters, who also would have to OK the plan.
