December 31, 2026 for the 2026 real-property application under Ohio's DTE 105A schedule; Jefferson County directs qualified homeowners to its Auditor's office for the application.
Senior relief
Jefferson County says the homestead exemption reduces taxes on the principal residence and up to one acre for eligible senior or disabled citizens; current Ohio rules generally require 2025 MAGI of $41,000 or less for new 2026 applicants, with enhanced relief for qualifying 100% disabled veterans.
Valuation limits
No general countywide parcel-value cap published. Ohio HB 920 reduction factors and the 10-mill limitation prevent voted levies from increasing revenue solely because of revaluation; HB 186, effective March 20, 2026, adds an automatic Inflation Cap Credit to qualifying 2025 tax-year bills payable in 2026 when eligible school-tax growth exceeds inflation.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
