Ohio hands out $12 billion a year in tax breaks, mostly to wealthy individuals and big corporations. In its last session, the General Assembly limited or eliminated nine, but it increased the cost of others, the report by Policy Matters Ohio said. Tax breaks on certain people and businesses are effectively tax increases on everybody else. “Unproductive tax breaks that favor corporations and wealthy Ohioans have riddled the state tax code for years,” the report said. The Policy Matters Ohio report said the legislature opted to look past evidence that some tax breaks weren’t performing as promised.
