Real estate tax due dates and penalties

The Real Estate Tax page explains collection timing, penalties, and how Butler County real estate taxes are handled.

First half 2025 real estate taxes were due Thursday, February 26, 2026. Payments are late unless they were postmarked on or before the due date.

Real estate taxes are collected twice each year. The first half due date is typically in mid to late February, and the second half due date is usually in early August. In Ohio, taxes for the previous year are collected during the current year.

A 5% late payment penalty is added to past due current year taxes if the balance due is paid in full within ten days after the due date. Otherwise, a full 10% penalty is added. The penalty is not reflected in the amount shown due on the Treasurer website.

How Butler County property taxes are calculated

Real estate taxes are calculated annually by the County Auditor. The tax bill is based on property valuation, millage, levies, special assessments, and any applicable reduction credits.

Property taxes are charged in mills. One mill equals one-thousandth of a dollar. Ohio residents pay a base tax rate of 10 mills, and voters may approve additional funds for public services.

The Auditor determines fair market value and taxable value. Taxable value is 35% of fair market value. The Auditor must perform a reappraisal once every six years and a value update in the third year after reappraisal.

If you disagree with an appraised value, an appeal may be filed between January 1 and March 31 each year.

Payment plans and penalty relief

For past due taxes, a Delinquent Tax Contract can allow monthly payments while the taxpayer stays current on upcoming tax bills. The payment plan form asks for contact information, parcel location, city, state, zip code, parcel number, email, and phone number.

Penalty relief is handled through an Application for Remission of Penalty. By law, penalties can be remitted only in certain circumstances. A completed application may be submitted online, mailed, or brought to the Treasurer’s Office at 315 High St 10th Floor, Hamilton, OH 45011.

The Treasurer also provides Forms & Applications for escrow, autopay, past due taxes, homestead, Board of Revision, owner occupancy credit, and manufactured home tax topics.

Autopay and escrow options

The Treasurer’s forms include monthly escrow, monthly autopay, semi-annual autopay, account change, and stop autopay options.

  • Escrow forms require a separate form for each property.
  • Parcel numbers should be entered without dashes.
  • Autopay forms require bank account information and a voided check, deposit slip, or bank letter.
  • Autopay changes must be received at least five days before the next scheduled debit.

Monthly autopay debits occur on the 15th of each month for the first five debits of the cycle. The sixth debit occurs on the due date shown on the semi-annual tax bill. Semi-annual autopay debits occur on the semi-annual tax due dates.

Tax estimates and Auditor reports
