Rate Breakdown

Property taxes in Montgomery County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Montgomery County

Property taxes in Montgomery County are determined by a combination of the property's assessed value and the local millage rates. The process begins with the Montgomery County Auditor, who performs a reappraisal every six years and an update every three years to reflect current market conditions. By Ohio law, property is assessed at 35% of its appraised market value; this figure is known as the "taxable value."

The total tax rate, expressed in mills (one dollar per $1,000 of taxable value), is a composite of rates from various taxing districts, including schools, townships, cities, and county services. These rates are voted upon by the community to fund local infrastructure and public services. To calculate your estimated annual tax, the Auditor’s office multiplies the taxable value by the effective tax rate, then applies any applicable tax reduction factors required by Ohio law to prevent tax windfalls due to inflation.

Available Exemptions

Ohio offers several programs to provide tax relief to eligible homeowners, helping to reduce the overall tax burden. These exemptions are managed at the county level but must meet state-defined criteria:

• Homestead Exemption: Designed for seniors (65 or older) and individuals with permanent disabilities. This program allows eligible homeowners to shield a portion of their home's market value from taxation, effectively reducing the tax bill.
• Disabled Veteran Exemption: Veterans who have been rated 100% service-connected disabled by the Department of Veterans Affairs may qualify for an enhanced homestead exemption, which provides a higher reduction in taxable value.
• Owner-Occupancy Credit: While state funding for this credit has shifted over time, qualifying owner-occupants may still see specific reductions depending on local levies.

Homeowners are encouraged to contact the Montgomery County Auditor’s office to verify eligibility requirements and filing deadlines, as applications must be submitted annually or upon a change in status.

Payment Schedule & Deadlines

Property taxes in Montgomery County are billed in two semi-annual installments. The first half is typically due in January, and the second half is due in July. The exact dates are set by the County Treasurer each year.

Taxpayers have several ways to pay, including online portals, mail, or in-person at the County Treasurer’s office. For those who prefer to spread out their payments, the County offers an escrow-style payment plan to help manage cash flow. It is critical to meet these deadlines; failure to pay by the specified due date results in a statutory 10% penalty and interest charges on the unpaid balance. Continued delinquency may eventually lead to tax liens or foreclosure proceedings.

Appealing Your Assessment

If you believe the Auditor's appraised value of your property exceeds its fair market value, you have the right to file an appeal. The process begins with the Montgomery County Board of Revision (BOR). Property owners must file a complaint (Form DTE 1) between January 1 and March 31 of the current tax year. During the hearing, you must provide evidence to support your claim, such as recent appraisals, sales data of comparable properties, or documentation of significant physical defects. The BOR will review the evidence and issue a written decision regarding whether to maintain or adjust your property's value.
