The bill comes from the Darke County Treasurer. The value it is based on is set by a separate office, the Darke County Auditor, which is who to ask if the value looks wrong. For how to look up and pay the bill, go to the county's own payment information.
The county auditor sets the value and the county treasurer sends the bill and collects it; the two offices share one real estate website, where a tax payment cart takes online payments. Ohio bills a year in arrears, in two halves, so 2025 taxes are paid during 2026. The due dates were not confirmed for this cycle, so use the date printed on your bill. Ohio law adds a 10% penalty to any half left unpaid after its due date, cut to 5% if the full amount due is paid within 10 days after the due date.
When are property taxes due in Darke County?
Two semiannual installments (statutory dates: first half by December 31, second half by June 20), but county treasurers commonly extend these, so actual due dates vary by county, often late January-February and late June-July (ORC 323.12).
Darke County does not publish the due dates for its bill on its own pages (checked September 23, 2026), so we do not print any here. The dates on your statement are the ones that bind you; who sends which bill is covered above.
