Who sends the property tax bill in Miami County, and how do you pay it?
The bill comes from the Miami County Treasurer. The value it is based on is set by a separate office, the Miami 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. There are two halves a year, billed a year in arrears, so 2026 taxes are paid in 2027. The Board of Revision is made up of the County Auditor, the County Treasurer and the President of the County Commissioners, and it rules on the property's value, not the tax amount. Manufactured home taxes follow a different schedule, due March 1 and July 31. Online payments go through the county's payment provider, MuniciPay. The treasurer asks owners not to pay before the bill arrives or the exact amount is confirmed, since paying an estimate can cause an overpayment.
When are property taxes due in Miami County?
For the Tax Year 2026 (payable 2027) bill, Miami County splits the bill into 2 payments, the first due February 14, 2027 and the last July 20, 2027. If a half is not paid by its due date, a 5% penalty applies for ten days after the due date, and a 10% penalty after that. Taxes left unpaid after the second half is due become delinquent and also accrue interest under Ohio law. Not receiving a bill does not excuse the penalty and interest. The treasurer offers delinquent tax contracts to help owners catch up on past due taxes, and liens on unpaid taxes can be sold at a tax lien sale.
| Payment | Due | Note |
|---|---|---|
| First half | February 14, 2027 | The treasurer's standing schedule lists the first half as due February 14. The 2027 bills had not been mailed when this was checked, and the date printed on your bill governs. February 14, 2027 is a Sunday and the next day, Presidents' Day, is a legal holiday in Ohio. Ohio law lets an act due by law on a Sunday or legal holiday be done on the next day that is neither, which would be Tuesday, February 16, 2027, but the treasurer has not said how it will treat this date, so paying by Friday, February 12 is safest. Mailed payments postmarked by the due date are accepted as on time. |
| Second half | July 20, 2027 | July 20, 2027 is a Tuesday. In 2026 the second half, normally due July 20, was extended to August 20 with the Ohio Tax Commissioner's approval because bills were delayed by the new inflation cap credit (House Bill 186), so check the date on your bill. |
From Miami County's published schedule, checked September 23, 2026. The county had not posted a calendar labeled for this cycle when we checked, so these dates come from state law and the county's standing schedule; the date on your bill is the one that binds you.

How to appeal your Miami County property assessment
In Miami County you appeal to the Miami County Board of Revision. The deadline: File a complaint against the value (form DTE 1) with the County Auditor, who serves as secretary of the Board of Revision, on or before March 31 of the year after the tax year you are disputing; complaints about 2026 values are due by March 31, 2027. A mailed complaint counts as filed on its U.S. Postal Service postmark date, but a private postage meter date does not count. State law allows only one complaint per parcel in each three-year valuation period unless something changed, such as a sale or damage. A Board of Revision decision can be appealed to the Ohio Board of Tax Appeals, or instead to the county Court of Common Pleas, within 30 days after the decision notice is mailed. Checked September 23, 2026 against state law, because Miami County does not restate them on its own pages.
