Frequently Asked Questions
How is the assessed value of a property determined in Union County?
Ohio counties assess taxable property using 35% of its appraised market value. The County Auditor periodically reviews market conditions, recent sales, property characteristics, improvements, and neighborhood trends before determining updated values used for taxation.
Will purchasing a home change my property taxes?
A property’s tax bill may change after a sale because future appraisals, updated market values, voter-approved levies, or changes in exemptions can affect the amount owed. The purchase price alone does not automatically determine future taxes.
Can I pay my Union County property taxes online?
Yes. Union County property owners generally have the option to pay taxes online through the County Treasurer’s payment system, in person, by mail, or through other approved payment methods offered by the county.
What is CAUV and who qualifies for it?
Current Agricultural Use Value (CAUV) is a special Ohio program that values qualifying farmland according to its agricultural use instead of market value. Eligible agricultural properties meeting program requirements may receive lower taxable values.
Do property tax rates stay the same every year?
No. Property Tax Rates can change annually because of new voter-approved levies, updates to property values, school funding requirements, and adjustments within each local Tax District, resulting in different tax obligations from one year to the next.
