Are you a senior citizen, a disabled individual, or a veteran living in Mahoning County, Ohio? If so, you might be leaving hundreds of dollars on the table every year by not taking advantage of the Ohio Homestead Exemption program. Property taxes can be a heavy financial burden, especially for those living on a fixed income. Fortunately, the Mahoning County Auditor offers an official property tax relief program designed to shield a portion of your home’s market value from local taxation.
In this comprehensive guide, we will break down exactly what the Mahoning County Homestead Exemption is, who qualifies based on the latest 2026 income guidelines, and a step-by-step process on how to apply online or via mail using the official DTE Form 105A.
What is the Mahoning County Homestead Exemption?
The Homestead Exemption is a statewide property tax relief program implemented by the Ohio Department of Taxation and administered locally by the Mahoning County Auditor. It allows qualifying homeowners to exempt a specific amount of their home’s market value from local property taxes.
For regular qualifying seniors and permanently disabled individuals, the program exempts $29,000 of the market value of their primary residence. For example, if your home is valued at $100,000, your property tax bill will be calculated as if the home is only worth $71,000.
For disabled veterans who meet specific criteria, the program is even more generous, offering an enhanced exemption of $58,000 of market value.

To quality for this tax reduction, the applicant must meet strict age, residency, and income requirements set by Ohio law.
1. General Requirements
- Ownership: You must own your home, manufactured home, or mobile home. This includes individuals listed on the deed, land contracts, or those holding a life estate.
- Primary Residence: The property must be your principal place of residence (domicile) as of January 1st of the tax year you apply. A person can only have one primary residence.

FAQs
Do I have to reapply for the Homestead Exemption every year?
No. Once your application is approved by the Mahoning County Auditor, it becomes permanent. However, every year you will receive a Continuing Homestead Exemption Application in the mail. If nothing has changed regarding your income, residency, or disability status, you can simply disregard the form. You only need to notify the auditor if your eligibility changes.
What happens if I move to a new house within Mahoning County?
The tax credit does not automatically transfer to your new house. If you move, you must file a new application under your new address to notify the fiscal office of your primary residence update.
Is it possible to apply late for a previous year?
Yes. If you met the qualifications in the prior year but missed the deadline, you can file a late application along with your current year’s application to request retroactive property tax credits.
