Since only a minority of mostly wealthier taxpayers itemize their deduction, eliminating the deduction for state income taxes would also help address the inequities of our tax system, where low- and middle-income Oklahomans pay more of their income in state and local taxes than do the wealthy. This proposal generated some interest but did not make its way into the final FY ’11 budget agreement.
