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 Greene County Auditor / Greene County Treasurer.
Relief programs
The filing guidance for this county is: December 31, 2026 for the 2026 application; Greene County requires ownership and occupancy on January 1 and describes filing after the first Monday in January through December 31. 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 a reduction of up to $29,000 of market value for the 2026 application period; the 2026 income limit for new senior/disabled applicants is $41,000 of 2025 Ohio modified adjusted gross income. The owner must own and occupy the home as the principal residence on January 1; enhanced disabled-veteran and public-service-officer surviving-spouse programs have separate rules.
No general county parcel-value cap was published. Ohio assesses real property at 35% of market value, reappraises every six years with triennial updates, and applies HB 920 reduction factors and the 10-mill limitation. House Bill 186, effective March 20, 2026, creates an Inflation Cap Credit for qualifying school-district/JVS levy growth; it is a tax credit/collection limitation, not a general cap on appraised or taxable parcel value.
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 under Ohio Revised Code §5715.19; Greene County's 2026 revaluation complaints are filed January 1–March 31, 2027.
