Frequently Asked Questions
What is the difference between market value and assessed value?
Market value represents what a property could reasonably sell for, while assessed value is the taxable value determined under Ohio assessment rules. Property taxes are calculated using the assessed value rather than the full market price.
Can I pay my Hardin County property taxes electronically?
Yes. Property owners can typically pay online through the county treasurer’s payment system, while other accepted methods often include mail, in-person payments, or mortgage escrow services.
Does refinancing my home affect property taxes?
No. Refinancing changes your mortgage terms but does not directly affect your property’s assessed value or annual property tax obligation unless another qualifying property change occurs.
How often are Property Tax Rates updated?
Property Tax Rates may change over time due to voter-approved levies, school funding needs, local government budgets, and adjustments made by taxing authorities throughout the county.
Why can neighboring properties have different tax bills?
