How Property Tax Works

Warren County, Ohio operates under a property tax system that funds essential local services including schools, county operations, townships, municipalities, and special districts. Property taxes are the primary revenue source for these local governments, supporting everything from education and public safety to infrastructure maintenance and community services.

The effective property tax rate in Warren County for tax year 2025 is $2.02935 per $1,000 of assessed valuation, though actual rates vary significantly by location within the county due to different combinations of school districts, municipalities, townships, and special taxing districts. Property is assessed at 35% of its fair market value, with assessments conducted countywide every six years and updated triannually. Homeowners should note that their specific tax rate depends on which taxing districts serve their property location, making it essential to verify the exact rate applicable to their address.

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in Warren County are additional property tax assessments that occur when there are changes in property ownership, new construction, or improvements made after the annual assessment date. These supplemental bills are calculated based on the difference between the old and new assessed values, prorated for the portion of the tax year remaining.

For example, if you purchase a home in Warren County in October 2025 that was previously assessed at $200,000 but now has a market value of $350,000, a supplemental tax bill would be issued for the increased assessed value ($52,500 difference at 35% assessment ratio) for the remaining months of the tax year. The supplemental tax would be approximately $1,065 ($52,500 × $20.2935 ÷ $1,000 × 3/12 months remaining).

Escrow & Property Taxes

Most mortgage lenders in Warren County require property tax escrow accounts, collecting monthly payments along with your mortgage payment to ensure taxes are paid on time. Lenders typically collect 1/12 of your annual property tax bill each month, plus a cushion amount as required by federal law. Your lender will pay your property taxes directly to Warren County on the February 25th and July 16th due dates.

Each year, your lender must provide an escrow analysis statement showing the previous year's activity and any adjustments needed for the coming year. If your property taxes increase due to reassessment or voter-approved levies, your monthly escrow payment will be adjusted accordingly. You can verify that your lender has made payments correctly by checking your account online at the Warren County Treasurer's website or calling (513) 689-4800. If you pay your mortgage off or don't have an escrow account, you'll be responsible for making tax payments directly to the county by the due dates.
