Tax estimator and tax rates

  • 2025 appraised value
  • Tax district where the property is located
  • Property type, including residential/agricultural or commercial/industrial
  • Reduction options, including owner occupancy credit and homestead reduction

The Auditor also states that the County Auditor cannot raise or lower property taxes. Tax rates are determined by the budgetary requests of governmental units, as authorized by voters, and computed under state procedures.

Failure to receive a tax bill does not remove the taxpayer’s obligation or mandatory penalties and interest. Wrongfully received tax bills should be returned.

Address changes must be sent in writing by completing the Change of Address Form and submitting it to Pamela Littlejohn, P.O. Box 1305, Springfield, OH 45501-1305.

Mailing note: A P.O. Box is a mailing address, not a walk-in service location.

Payment methods and escrow options

Clark County accepts real estate tax payments by cash, money order, personal check, cashier’s check, credit card, and debit card. A processing fee is assessed for credit or debit card payments.

The Treasurer’s Office also offers a real estate escrow program for monthly installment payments toward current semi-annual real estate taxes. The program requires a real estate escrow agreement with the Treasurer’s Office.

Escrow payments may be made by cash, check, money order, or ACH debit with a financial institution or bank. There is no service charge for using the escrow program.

Mailed property tax payments

Ohio law relies on the postmark date to decide whether a mailed property tax payment is timely. Clark County advises taxpayers mailing payments near a deadline to allow extra mailing time, ask about local postmark procedures, request an in-person hand-stamped postmark, or use another payment method.

Payments postmarked after the due date may be subject to penalties required by law.

The Clark County Treasurer offers delinquent payment plans for real estate and manufactured homes under Ohio Revised Code Section 323.31. Contact the Treasurer’s Office to review delinquent payment plan options.

The Clark County Auditor also provides a delinquency report that lists delinquency search results, including parcel number, taxpayer, certified year, vacant status, and amount.
