How Gallia County Assesses Property
Assessed by: Gallia County Auditor's Office
Assessment cycle: sexennial with triennial updates
Notices typically mailed: Spring (typically mid-April)
In Gallia County, property tax bills are calculated based on assessed value, which represents 35% of your property's market value as determined by the County Auditor. The market value is what your property would sell for in the current real estate market, while the assessed value is the amount subject to taxation. For example, if your home's market value is $155,600 (the county median), at Ohio's 35% assessment ratio your assessed value would be $54,460, resulting in approximately $1,068 in annual taxes at the county's effective rate of 1.29%. This assessment ratio is uniform across all Ohio counties and set by state law.
The Appeal Process
Appeals are heard by the Board of Revision. The Gallia County Board of Revision consists of three members: the County Auditor, County Treasurer, and President of the County Commissioners. Hearings are formal legal proceedings where you present evidence supporting your property's lower market value, and the burden of proof rests with the property owner to demonstrate overvaluation.
Step 1: Verify your current assessed value by searching your property on the Gallia County Auditor's website at https://auditor.gallianet.net or calling(740) 446-4612.
Step 2: Gather supporting evidence including recent comparable sales (within the last 3 years), a professional appraisal, photos showing property condition issues, repair estimates, or other documentation proving your property is overvalued.
Step 3: Complete DTE Form 1 (Complaint Against the Valuation of Real Property) available from the Auditor's office or Ohio Department of Taxation website. You must have the form notarized unless filing through an e-file portal.
Step 4: Submit your completed form and evidence to the Gallia County Board of Revision between January 1 and March 31. Ensure it is postmarked or received by March 31, 2026.
Step 5: Attend your Board of Revision hearing when scheduled. You will receive notice of your hearing date, typically at least 10 days in advance. Present your evidence and testimony to support your requested value.
Step 6: Receive the Board's written decision, typically within 90 days of your hearing. The decision will state whether your value was changed and the new assessed value.
Step 7: If dissatisfied with the Board of Revision decision, you have 30 days from the decision date to appeal to either the Ohio Board of Tax Appeals (free of charge) or the Court of Common Pleas (requires filing fee).
