Assessment cycle: sexennial reappraisal with triennial update

Notices typically mailed: Spring (typically by mid-April)

In Harrison County, property taxes are calculated based on the assessed value, which is 35% of the property's fair market value as mandated by Ohio law. For example, if your home's market value is $81,800 (the county median), at Ohio's 35% assessment ratio your assessed value would be $28,630, resulting in approximately $781 in annual taxes at the county's effective rate of 0.95%. The Harrison County Auditor determines fair market value using a uniform approach based on comparable sales data and market conditions as of January 1st of the tax year.

The burden of proof is on the taxpayer, and the Board will make its decision based on evidence submitted and appraisal research.

Your appeal must be received by or postmarked to the Harrison County Auditor's Office by this date. Late filings are not accepted under Ohio law, and you will lose your right to challenge your 2025 assessment if you miss this deadline. Appeals are generally only accepted during a limited window from January 1 through March 31 each year, so it's important to act quickly if you believe your property is overassessed.
How do I file a property tax appeal in Harrison County?
To file a property tax appeal in Harrison County, you must complete DTE Form 1 (Complaint Against the Valuation of Real Property) and submit it to the Harrison County Auditor's Office along with supporting documentation. You can file by mail to 100 West Market Street, Cadiz, OH 43907, or in person during office hours Monday-Friday 8:00am-4:00pm. Be sure to include evidence such as recent comparable sales, professional appraisals, or photos showing property issues. The filing of a complaint initiates a legal proceeding, so read the form instructions carefully—incomplete or flawed forms may result in dismissal, which counts as your one filing allowed per three-year period.
What is the homestead exemption worth in Harrison County?
The homestead exemption in Harrison County provides tax relief to qualified seniors (65+), disabled persons, and surviving spouses by reducing the taxable value of their primary residence. While the exact savings depends on your property value and tax district, the average savings in similar Ohio counties is around $360 per year for the standard exemption. The exemption amount is indexed annually for inflation. To qualify for 2026, you must have an Ohio Adjusted Gross Income of $40,000 or less and own and occupy your home as your principal residence. Disabled veterans with 100% service-connected disability receive an enhanced exemption of $52,300 from their home's value, typically saving $700 or more annually, with no income restrictions.
What happens at a Board of Revision hearing in Harrison County?
Board of Revision hearings in Harrison County are held at the County Courthouse at 100 West Market Street in Cadiz and typically last about 20 minutes. The hearing is recorded and open to the public. You will present your case first, including testimony and evidence supporting your requested value change. If applicable, a counter-complainant (usually the auditor's office) will then present their case. The three-member Board—consisting of the County Auditor, County Treasurer, and President of County Commissioners (or their representatives)—may ask questions at any time. The burden of proof is on you as the taxpayer, so bring strong evidence like comparable sales, appraisals, and documentation of property issues. After the hearing, the Board will make a decision and notify you in writing by certified mail.
How much can I save by appealing my property taxes in Harrison County?
The amount you can save by appealing your property taxes in Harrison County depends on how much your assessment is reduced and your local tax rate. With Harrison County's effective tax rate of 0.95%, every $10,000 reduction in your assessed value saves approximately $95 per year in property taxes. For example, if you successfully reduce your market value from $100,000 to $90,000, your assessed value drops from $35,000 to $31,500 (at the 35% assessment ratio), saving you around $333 annually. Statistics suggest that about 25% of homes nationwide are overassessed by an average of $1,346 per year. Given Harrison County's lower-than-average tax rates, your potential savings will be proportional to the degree of overassessment and the evidence you can provide to support a lower valuation.
What evidence do I need for a Harrison County property tax appeal?
For a successful property tax appeal in Harrison County, you need compelling evidence that your property's market value is lower than the auditor's assessment as of January 1st of the tax year. The strongest evidence includes recent sales of comparable properties in your neighborhood (ideally within the past year), a professional independent appraisal dated near January 1st, photographs documenting condition issues or deferred maintenance, and repair estimates from licensed contractors. You can also provide documentation of factors that negatively impact your value, such as environmental issues, zoning changes, or economic obsolescence. The Board of Revision makes decisions based on evidence submitted, so simply stating 'I think my value is wrong' without documentation will not succeed. Research comparable properties using the county's online property search tool or GIS map to build a strong case.
When does Harrison County reassess property values?
Harrison County follows Ohio's state-mandated property valuation schedule, which requires a full Sexennial Reappraisal every six years and a Triennial Update at the three-year midpoint. The most recent Sexennial Reappraisal was completed for tax year 2023, which included a physical examination and appraisal of every residential, commercial, industrial, and agricultural parcel in the county. The next Triennial Update will occur in 2026, which does not require visiting each property but instead uses statistical analysis of sales and market data to adjust values. Assessment notices are typically mailed in the spring, usually by mid-April, and include both market and assessed values along with an estimated property tax bill. Property owners should review these notices carefully and consider appealing if they believe their property is overvalued.
Can I appeal my Harrison County property taxes online?
Harrison County does not currently offer a fully online filing portal for property tax appeals through the Board of Revision, but you can access forms and information on the county's website at https://harrisoncountyohio.gov. You must complete DTE Form 1 (Complaint Against the Valuation of Real Property) with your original ink signature—electronic signatures are not accepted. You can download the form from the Harrison County Auditor's website or the Ohio Department of Taxation website, but the original signed form must be submitted by mail or in person to the Auditor's Office at 100 West Market Street, Cadiz, OH 43907.
