Tax relief and valuation review
A homestead exemption, senior-relief program, or valuation protest can change the amount a homeowner owes—but only if the filing reaches the right local office in the correct window. Use the verified county guidance below as your working checklist, then confirm the current form and deadline with Harrison County Auditor (Clint A. Barr) / Harrison County Treasurer (Vicki Sefsick).
Relief programs
The filing guidance for this county is: Harrison County describes filing by the first Monday in June for the current year; for the 2026 application, use the county's form/instructions and the state DTE 105A December 31 deadline. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Open homestead applicationOhio Homestead Exemption: qualifying homeowners age 65+, permanently and totally disabled homeowners, and eligible surviving spouses may receive up to a $29,000 market-value reduction for 2026; new applicants use the $41,000 2025-income limit and must own and occupy on January 1.
Ohio HB 186 (effective 2026) creates an Inflation Cap Credit limiting growth of qualifying unvoted school-district millage to inflation; HB 335 limits inside-millage growth. These affect tax collection, not a general parcel appraised-value cap.
Appealing an assessment
Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.
Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.
Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.
The verified protest guidance for this county is: January 1–March 31, 2026 for tax year 2025; valuation complaints are filed with the Harrison County Board of Revision through the Auditor before April 1. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
