Understanding Ohio Real Estate Taxes: Arrears, Prorations, and Closing

Buying or selling a home in Ohio involves a unique system for handling property taxes. Unlike states where residents pay for the current year, Ohio bills property taxes one year backward. Understanding this billing system and how it affects the closing process ensures a smooth transaction and prevents unexpected financial surprises. 

Paying a Year in Arrears 

The fundamental rule of Ohio real estate taxes is that they are paid a year in arrears. This means the property tax bills you receive in 2026 actually cover the taxes owed for 2025. County auditors calculate the taxes at the end of the year, and counties typically issue bills in two half-year installments due the following year. 

Because of this built-in delay, a person selling a home always owes taxes for the time they lived in the house, even though the county has not generated the bill yet. When a property transfers to a new owner, the buyer will eventually receive a tax bill for time they did not even own the home. 

Standard Tax Proration 

To solve this issue, the title company settles these unpaid taxes during the closing process through tax proration. The seller must compensate the buyer for the taxes that accumulated during the seller's ownership period. 

At the closing table, the seller gives the buyer a financial credit against the purchase price. The seller does not pay the county directly. Instead, when the actual tax bill arrives months later, the new buyer pays the county in full, utilizing the funds the seller credited to them at closing. This credit appears clearly on the closing disclosure or settlement statement. 

Short-Period Proration (Montgomery County Short-Period Proration) 

Short-period proration—also known as the "Montgomery County short-period proration"—is the exception rather than the rule in Ohio. This method is used in certain transactions to ensure fairness and accuracy. It calculates the exact number of days the seller owned the property during the current, unbilled tax year. 

To make this exchange completely fair and accurate, title companies use a specific calculation known as short-period proration. This formula determines the exact number of days the seller owned the property during the current, unbilled tax year. 

For example, if a seller closes on a home on March 31, they owned the property for 90 days of the current calendar year. The title company takes the most recent annual tax amount, divides it by 365 to find the daily tax rate, and multiplies that exact daily rate by 90. The seller then credits this precise amount to the buyer. Furthermore, the seller must also credit the buyer for the entire previous year if those half-year installment bills remain unpaid at the time of closing. 

Navigating property taxes during an Ohio real estate transaction requires careful attention to the calendar. By understanding how billing in arrears and short-period prorations function, buyers and sellers can approach closing day with confidence. Always review your settlement documents with your title agent and real estate professional to verify these calculations, ensuring everyone pays exactly their fair share.
