Property taxes in West Mifflin

Every property here gets three real estate tax bills: one from the county, one from West Mifflin and one from the school district. The county's rate is the same everywhere. The other two are set locally, which is why two similar houses a mile apart can owe very different amounts. How the bills are worked out.

Same school district

One other place shares the West Mifflin Area school district with West Mifflin, so the school tax rate is the same.
