If the property tax records indicate an overpayment of real estate taxes, one or more parties may be eligible for a refund. Overpayments can occur for several reasons. Often they are the result of recent ownership changes where both the previous and current owners make payment toward the same tax charges. Sometimes they are the results of adjustments to the tax charges made after the billing has occurred and payments submitted. Instructions for Submission: If you have any questions, please contact the Treasurer's Office at (937) 225-4010 Option 1. Unclaimed property is any financial asset for which an owner has not generated activity for an extended period of time. This may include savings, checking, certificate of deposit accounts; payroll (wages, bonuses, commissions); stocks and bonds (un cashed dividends, interest checks, underlying shares principle); insurance proceeds; credit balances; customer deposits; travelers checks; money orders and other intangible interests or benefits.
