Exemptions & appeals

Allen County's official homestead page states the DTE 105A must be received by December 31, 2026 (not merely postmarked) for the 2026 application year.
Senior relief
Ohio Homestead Exemption (DTE 105A): qualifying homeowners age 65 or older, permanently and totally disabled, or an eligible surviving spouse may receive the exemption on an owner-occupied principal residence. For 2026 applications, the current Ohio income threshold for new applicants is $41,000 Ohio adjusted gross income; county filing instructions and documentation requirements apply. Allen County says the application is paper-only and the exemption continues annually unless the owner's status changes.
Valuation limits
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.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
