NO further tax cuts are in the offing for the foreseeable future, so Oklahoma’s tendency to tax lower-income citizens disproportionately is also unlikely to change any time soon.
The state is rated as having an exceptionally regressive tax system by the Institute on Taxation and Economic Policy (ITEP), which says low- and moderate-income Oklahomans surrender a greater portion of their incomes to taxes than those with higher incomes.
The problem is multifaceted and begins with the fact that Oklahoma’s highest personal income tax rate (now at 5.5 percent) kicks in at a relatively low income level.
