Ohio Homestead Exemption: Meaning, Form DTE 105A Guide & Tax Savings
In Ohio, the Homestead Exemption allows qualifying senior citizens (65+) and permanently and totally disabled homeowners to shield the first $29,000 of their home’s market value from local property taxation.
To qualify for the standard senior exemption in 2026, your Ohio Adjusted Gross Income (OAGI) must be $41,000 or less based on the previous year’s tax filing. Meanwhile, 100% service-connected disabled veterans and public safety surviving spouses receive a larger $58,000 market value exemption with zero income restrictions.
Ohio Insider Tips: What Generic Sites Won’t Tell You
Property tax relief in Ohio is administered entirely by your local County Auditor (e.g., Franklin County Auditor, Cuyahoga County Auditor, Hamilton County Auditor), but the income guidelines are set strictly by the Ohio Department of Taxation (ODT).
The OAGI Calculation Trap
Ohio uses **Ohio Adjusted Gross Income (OAGI)**, not federal AGI or gross wages. OAGI includes your Social Security benefits only if they are taxable federally, but pension distributions, traditional IRA withdrawals, and capital gains count fully. If your line 3 on your Ohio IT-1040 is even $1 over $41,000, your exemption will be automatically rejected.
Veterans: Don’t File the Wrong Form!
Many 100% disabled veterans mistakenly file standard Form DTE 105A because it’s easier to find online. This is a mistake. If you are a 100% service-connected disabled veteran, you must file Form DTE 105I to unlock the $58,000 exemption with zero income caps.
Trust Ownership Rules
If you placed your Ohio home into a revocable living trust for estate planning, you still qualify for the Homestead Exemption as long as you are the creator (trustor) of the trust and maintain beneficial ownership and primary occupancy as of January 1.
Exact Micro-Guide: How to File Form DTE 105A with Your County Auditor

Verify Your Age or Disability Status
You must turn 65 by December 31 of the application year, or provide a certificate of total and permanent disability signed by a licensed physician or a state/federal agency (like Social Security Administration).

Submit your completed application to your County Auditor’s Real Estate Division either online through their portal, via certified mail, or in person.
Deadline Note: While applications can technically be submitted through December 31 of the tax year, filing early in the year ensures it reflects on your upcoming tax bills.
How the $29,000 Ohio Homestead Exemption Works
The Ohio Homestead Exemption operates as a direct market value credit. By shielding $29,000 of your home’s appraised value from taxation, your local millage rates are applied to a lower taxable base.
- Without Exemption: $150,000 appraised value billed at full rate = $9,000 gross tax (before rollback credits).
- With Homestead Exemption: $150,000 − $29,000 = $121,000 taxable market value.
- Total Estimated Annual Savings: Across Ohio counties, the $29,000 exemption typically saves homeowners $500 to $800+ per year in property taxes.
Comparing Ohio Property Tax Relief Tiers
Ohio offers three distinct tiers of the Homestead Exemption. You cannot stack them; you must apply for the highest tier you qualify for.
| Exemption Tier | Target Beneficiary | Appraised Value Shielded | Income Limit (OAGI) |
|---|---|---|---|
| Standard Senior | Homeowners age 65+ by December 31 | $29,000 market value | $41,000 or less |
| Disabled Person | Totally and permanently disabled as of Jan 1 | $29,000 market value | $41,000 or less |
| Disabled Veteran | 100% service-connected disabled veteran (Form DTE 105I) | $58,000 market value | Zero / No Income Limit |
| Public Safety Spouse | Surviving spouse of first responder killed in line of duty | $58,000 market value | Zero / No Income Limit |

Common Ohio Homestead Application Rejections
Exemption Denied Due to OAGI Overage
If your Ohio Adjusted Gross Income (OAGI) was $41,001 last year, your application will be automatically rejected by the auditor’s computer system.
Next Step: Review your IT-1040 line 3 to ensure all allowable adjustments were claimed. If your income dropped significantly this year, you can reapply next year.
Missed the January 1 Ownership Test
You must own and occupy the home as of January 1 of the tax year. Buying a home in February and moving in means you must wait until the following year to file.
Next Step: File your Form DTE 105A immediately after taking ownership so it is logged in the county auditor’s system for the next tax cycle.
Property Held in an Irrevocable Trust
While revocable living trusts qualify, irrevocable trusts often disqualify the homeowner because the applicant no longer holds legal beneficial title.
Next Step: Consult your estate planning attorney and the County Auditor’s legal division to review the exact trust language.
Auditor Sent a Continuing Audit Letter
Ohio auditors periodically send income verification questionnaires to ensure your income hasn’t exceeded the threshold. Ignoring this letter results in cancellation.
Next Step: Fill out the audit questionnaire immediately and return it with your tax return to prevent your homestead credit from being stripped.
