Governor Kasich’s tax proposal would further reinforce the shift in Ohio’s state and local tax system in favor of affluent residents and against those with lower or middle incomes. Under the plan, Ohioans who made under $56,000 last year – those in the bottom three-fifths of the income spectrum – on average would pay more tax than they do now. Meanwhile, those in the top 1 percent, who made more than $457,000 last year, would average an annual gain of $2,412. Those are among the key findings of an analysis done for Policy Matters Ohio by the Institute on Taxation and Economic Policy (ITEP), a Washington, D.C.-based research group with a sophisticated model of the tax system. On average, ITEP found, taxpayers in the middle fifth, who made between $36,000 and $56,000 last year, would see an annual increase in taxes under the plan of $44.
