Glad you asked.
The Ohio Department of Taxation reports the tax effort -- burden -- for each district in Ohio. Tax burden is defined as the amount of local school district taxes collected as a percentage of personal income. Despite the spin to the contrary, Olentangy has a relatively high tax burden. In fact, the district is the 101st highest ranked out of the state's 614 districts based on the tax department's latest report. It's all right here in Appendix D.
note: School-related property taxes in Olentangy are rising at an annualized rate of over 7% per year, meaning that school-related property taxes are taking an ever-increasing portion of the incomes of district residents. In fact, the district tax burden has increased 61% over the latest seven year's worth of department data.
