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 Adams County Auditor / Adams County Treasurer.
Relief programs
The filing guidance for this county is: Adams County's official homestead page says the DTE 105A application must be filed on or before December 31, 2026; submit to the County Auditor for the principal residence. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Open homestead applicationAdams County Homestead Exemption: qualifying senior, permanently/totally disabled homeowner, or eligible surviving spouse may receive a reduction of up to $25,000 in market value on the principal residence; new applicants are subject to Ohio's income test and must file DTE 105A.
Ohio HB 920 reduction factors limit increases in collections from voted levies on carryover property; the 20-mill floor, inside millage, new levies, and statutory exceptions still apply. This is a tax-collection limitation, not a general parcel valuation cap; taxable value and effective rate vary by tax district.
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 under Ohio Revised Code 5715.19 for the 2025 tax year; the county Board of Revision may accept a complaint later only when the statutory collection-date extension applies. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
