December 31, 2026 for a 2026 real-property homestead application; file with the county Auditor under Ohio's DTE 105A schedule.
Senior relief
Montgomery County's Homestead Exemption is available to qualifying senior citizens, permanently disabled persons, and eligible surviving spouses; the county's Auditor administers the program and provides a Homestead Hotline at 937-225-4341. New 2026 applicants generally must meet the $41,000 2025 Ohio MAGI limit and may shield up to $29,000 of market value; enhanced veteran programs have separate requirements.
Valuation limits
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 automatic 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.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
