To successfully appeal your property tax assessment in Mahoning County, you must file a formal complaint with the Board of Revision by the March 31 deadline. This process specifically challenges the Auditor’s 2026 market value appraisal rather than the tax rate. Use Form DTE 1 to submit your claim, ensuring you provide strong evidence like recent comparable sales or a certified appraisal dated as of January 1.
This guide breaks down exactly how to navigate the Mahoning County Board of Revision (BOR) to potentially lower your property tax burden.
Understanding the Mahoning County Tax System
Before you appeal, you need to know how the math works. The Mahoning County Auditor revalues properties every three or six years. Your tax bill is calculated based on 35% of your property’s Market Value (this is called the Assessed Value).
If the Auditor values your home at $200,000, but similar homes in your neighborhood are selling for $160,000, you are overpaying. The goal of an appeal is to prove that the Auditor’s market value estimate is incorrect.
Who Can File an Appeal?
In Mahoning County, the following parties are eligible to file:
- Property Owners: Anyone who holds the deed to the property.
- Leaseholders: Under specific legal conditions.
- School Boards/County Officials: Though they usually file to increase values, not decrease them.
The Deadline: Mark Your Calendar
The Mahoning County Board of Revision (BOR) accepts appeals only once a year.
Key Date: You must file between January 1st and March 31st. Applications received after March 31st will not be considered until the following year.
How to File: The DTE Form 1
To start the process, you must complete DTE Form 1 (Complaint Against the Valuation of Real Property). You can find this on the Mahoning County Auditor’s website. When filling it out, pay close attention to:
- Item 6: This is where you state what you believe the correct market value is.
- Item 10: This is where you justify your request with evidence.
5. Gathering Evidence (The Most Critical Step)
The Board of Revision will not lower your taxes just because “taxes are too high.” You must provide Substantial Evidence. The strongest evidence includes:
- Recent Sales Comparison (Comps): Find 3-4 homes similar to yours in size and condition that sold in your neighborhood within the last year for less than your appraised value.
- Professional Appraisal: A report from a certified independent appraiser is the “Gold Standard” for evidence.
- Structural Damage: If your home has foundation issues, a failing roof, or fire damage, provide photos and repair estimates from contractors. These lower the market value of the home.
6. The Hearing Process
Once you submit your form, you will be scheduled for a hearing, usually held at the County Courthouse or Auditor’s Office in Youngstown.
- Present Facts: Avoid emotional arguments. Focus strictly on the “Market Value” of the property.
- The Board: The board consists of representatives from the Auditor, Treasurer, and County Commissioners. They may ask you questions about your evidence.
- Be Professional: Bring extra copies of your evidence for each board member.
