Ontario property tax rate vs the rest of Ohio
Ontario has an effective property tax rate of 1.51% — its median real-estate tax bill ($2,462) as a share of its median home value ($163,300). That is above Ohio's 1.36% state average, and ranks the 127th highest of the 293 Ohio cities we track.
Your bill is set by overlapping local taxing bodies — the city, the county, and the school district — so the same home value in a neighbouring town can owe a very different amount. The calculator above starts from Ontario's 1.51% effective rate; adjust it to your exact parcel or add a homestead exemption for a closer estimate.

How affordable is property tax in Ontario?
The typical Ontario homeowner pays about $2,462 in property tax against a median household income of $65,905 — roughly 3.7% of income a year. That ratio is a quick way to weigh the real burden of property tax, since a modest rate on an expensive home can still be a large dollar bill.
How Ontario property tax is calculated
Your assessor sets Ontario's assessed value, and local millage rates from the city, county and school district are applied to it; the 1.51% effective rate rolls all of that into one share of market value. To estimate your tax, multiply your home value by 1.51% (or your exact local rate), then subtract any homestead or senior exemption you qualify for. The calculator above does this and shows both the annual bill and the monthly escrow amount.
