Henry County Property Tax Appeal — Ohio

Rob Hartley·Updated April 3, 2026

Henry County is located in northwestern Ohio with its county seat in Napoleon, a city of approximately 8,655 residents. The county has a total population of approximately 27,662 and includes other notable cities such as Deshler, Liberty Center, Holgate, and McClure. Property tax appeals are particularly important in Henry County because while the median annual property tax bill of $1,746 is below the national median of $2,400, the county's effective tax rate of 0.78% means homeowners should ensure their assessments accurately reflect market conditions. Henry County's median home value of approximately $213,460 is below Ohio's median, but the county ranks 748th nationally in median property taxes, making accurate assessments critical for fair taxation.

How Henry County Assesses Property

35%of market value

Assessed by: Henry County Auditor's Office

Assessment cycle: triennial

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

In Henry County, property taxes are calculated by first determining your property's fair market value, then multiplying by Ohio's 35% assessment ratio to arrive at the assessed value. For example, if your home's market value is $213,460 (the county median), your assessed value would be $74,711 (calculated as $213,460 × 0.35). At Henry County's effective tax rate of 0.78%, this would result in approximately $1,665 in annual property taxes. The Ohio Department of Taxation requires the Henry County Auditor to adjust property values every three years through a triennial reappraisal cycle.

The Appeal Process

Appeals are heard by the Board of Revision. After filing your appeal, you will receive written notice at least 10 days before your scheduled hearing. The hearing takes place before the three-member Board of Revision and typically lasts approximately 15 minutes. You will present your evidence and answer questions from Board members about your property's value. The Board decides cases based on property value, not tax amounts.

Step 1: Review your property assessment notice and compare your assessed value to recent sales of comparable properties in your area. Your assessed value should be your market value multiplied by 35%. Check the Henry County Auditor's property search tool online to verify current values.

Step 2: Gather supporting evidence for your appeal, including recent comparable home sales (within the last 3 years), a professional appraisal dated near January 1 of the tax year, photographs of property defects or damage, repair estimates, or listing agreements if your property was recently on the market.

Step 3: Complete DTE Form 1 (Complaint Against the Valuation of Real Property), available on the Henry County Auditor website or by calling(419) 592-1956. Fill out all required fields including your opinion of the property's full market value, current assessed value, and detailed reasons justifying your requested value change.

Step 4: Submit your completed DTE Form 1 along with all supporting documentation to the Henry County Board of Revision between January 1 and March 31. Submissions must be received or postmarked by the deadline. Include copies of all evidence, as original documents become part of the Board's permanent record.

Step 5: Attend your Board of Revision hearing after receiving notice at least 10 days in advance. Present your case to the three-member Board consisting of the County Auditor, County Treasurer, and President of County Commissioners. Be prepared to answer questions about your property and evidence. The Board will issue a written decision after reviewing all testimony and documentation.

Step 6: If dissatisfied with the Board of Revision's decision, you may appeal to the Ohio Board of Tax Appeals by filing DTE Form 4 within 30 days of the decision notice mailing date, or appeal to the Court of Common Pleas within the same timeframe.

Appeals must be submitted between January 1 and March 31 each year, and your filing must be received by the County Auditor's office or postmarked by the deadline. Ohio law does not allow late filings to be accepted under any circumstances.

Box 546, Napoleon, OH 43545 by mail (postmarked by March 31), in person at 660 N Perry Street, or by fax to(419) 592-4024. You will receive notice of your hearing date at least 10 days in advance.

What evidence do I need to win my Henry County property tax appeal?

Strong evidence is critical for a successful property tax appeal in Henry County. The most compelling evidence includes recent comparable sales of similar homes in your area that sold within the last three years, showing lower values than your assessed value. A professional appraisal dated near January 1 of the tax year carries significant weight, especially if the appraiser attends your hearing to testify. Other valuable evidence includes photographs documenting property defects, structural damage, or needed repairs; contractor estimates for repair costs; and listing agreements if your property was recently on the market. The Henry County Board of Revision cannot consider tax rate complaints or percentage increases in your taxes—they only evaluate whether your property's market value assessment is accurate. Submit all evidence when filing your DTE Form 1 or at least 5 days before your scheduled hearing.

How does Henry County calculate my property taxes with the 35% assessment ratio?

Henry County calculates property taxes using Ohio's 35% assessment ratio system. First, the County Auditor determines your property's fair market value by studying recent sales of comparable properties. This market value is then multiplied by 35% to arrive at your assessed value—the figure used for tax calculation. For example, if your home's market value is $200,000, your assessed value would be $70,000 ($200,000 × 0.35). Finally, the local tax rate for your specific district is applied to this assessed value to determine your annual tax bill. Henry County has 40 different taxing districts, each with its own rate. If you believe your market value is too high, you can appeal by filing DTE Form 1 with the Board of Revision between January 1 and March 31.

What happens at a Henry County Board of Revision hearing?

Your Henry County Board of Revision hearing is a quasi-judicial proceeding where you present evidence to support your requested property value. The Board consists of three members: the County Auditor, County Treasurer, and President of the County Commissioners (or their designees). You'll receive at least 10 days advance notice of your hearing date. During the approximately 15-minute hearing, you'll present your evidence—such as comparable sales, appraisals, or photographs—and explain why your property's assessed value should be changed. Board members will ask questions about your property and the evidence you submitted. The hearing focuses solely on property value, not tax rates or tax amounts. After hearing all testimony and reviewing documentation, the Board will issue a written decision. If you disagree with their decision, you have 30 days from the mailing date to appeal to the Ohio Board of Tax Appeals or Court of Common Pleas.

What is the homestead exemption worth in Henry County, Ohio?

The homestead exemption in Henry County provides significant property tax relief for qualifying residents by exempting a portion of their home's market value from taxation. For seniors age 65 and older and disabled persons, the exemption amount is indexed annually for inflation. Disabled veterans with 100% service-connected disability receive an enhanced exemption of $56,000 in market value (2024 tax year amount) with no income limits. Traditional homestead applicants must have household adjusted gross income not exceeding $33,600 and occupy the property as their principal residence. To apply, complete Form DTE 105A (or DTE 105I for disabled veterans) and submit it to the Henry County Auditor's Office at 660 N Perry Street, Napoleon, OH 43545 before December 31. Once approved, the exemption continues automatically each year unless your circumstances change, potentially saving hundreds of dollars annually on your property tax bill.

How often does Henry County reassess property values and when will my next assessment occur?

Henry County follows Ohio's triennial reappraisal cycle, meaning the County Auditor must adjust property values to reflect current market conditions every three years as required by the Ohio Department of Taxation. The county conducts a full reappraisal every six years with an update performed during the third year after each reappraisal. Property owners receive assessment notices in the spring, typically by mid-April, showing both market value and assessed value for the upcoming tax year. These values are based on property conditions as of January 1 of that tax year. Even if there hasn't been a recent county-wide reappraisal, property owners can file an appeal with the Board of Revision between January 1 and March 31 of any year if they believe their property's assessed value doesn't accurately reflect its true market value. Contact the Henry County Auditor's Office at(419) 592-1956 for information about the county's most recent reappraisal year and upcoming assessment schedules.
