Trumbull County Property Tax Appeal — Ohio

Rob Hartley·Updated April 3, 2026

Trumbull County is located in northeastern Ohio with Warren serving as its county seat. The county has a population of approximately 201,977 (2020 census) and includes major cities such as Warren, Niles, Hubbard, Cortland, and Girard. Property tax appeals matter significantly in Trumbull County because homeowners face an effective tax rate of approximately 1.38-1.40%, which is close to Ohio's state average of 1.4% but notably higher than the national median effective rate of 1.0%. With a median home value around $141,800 and median annual property tax bills ranging from $1,419 to $1,518 depending on location, Trumbull County residents pay considerably less than the national median property tax bill of $2,400, though the tax burden as a percentage of home value remains above the national average.

How Trumbull County Assesses Property

35%of market value

Assessed by: Trumbull County Auditor's Office

Assessment cycle: triennial

Notices typically mailed: mid-April (Spring)

In Trumbull County, property taxes are calculated using Ohio's statewide 35% assessment ratio. The Trumbull County Auditor determines each property's market value based on recent sales, property characteristics, and local market conditions, then applies the 35% assessment ratio to calculate the assessed (taxable) value. For example, if your home's market value is $141,800 (the county median), your assessed value would be $49,630 (35% of $141,800). At the county's effective tax rate of approximately 1.38%, this results in an annual property tax bill of approximately $1,957. This calculation varies by location within the county based on local millage rates for schools, townships, and cities.

The Appeal Process

Appeals are heard by the Board of Revision. The Board of Revision hearing is a formal proceeding where you present your evidence to three members (or their representatives) from the County Auditor, Treasurer, and Commissioner offices. You can bring documentation, photographs, appraisals, and comparable sales data to support your case. The Board will review all evidence and may ask questions before making a decision.

Review your property assessment notice received in mid-January and verify the market value assigned to your property by comparing it to recent sales of similar homes in your neighborhood.

Gather supporting evidence for your appeal, including recent property appraisals, comparable sales data from similar properties that sold for less, photographs documenting property condition or defects, repair estimates for needed work, and any other documentation that supports a lower valuation.

Complete DTE Form 1 (Complaint Against the Valuation of Real Property) available from the Trumbull County Auditor's website or office. Clearly state your name, relationship to the property, parcel number, current assessed value, and your opinion of the correct market value. The form requires a notary unless filed through an e-filing portal.

File your completed appeal form with the Trumbull County Auditor's Office (serving as Secretary to the Board of Revision) by the March 31st deadline. You can submit by mail, in-person, or email. Late filings are rejected with no exceptions.

Attend the Board of Revision hearing when scheduled. The Board consists of representatives from the Auditor, Treasurer, and County Commissioners. Present your evidence and explain why your property value should be reduced. The burden of proof is on you as the complainant.

Receive the Board of Revision's decision in writing. The Board may increase, decrease, or maintain your property's assessed value based on the evidence presented. Decision processing can take 90 days or longer depending on case volume.

If you disagree with the Board of Revision's decision, you have 30 days from the decision date to file an appeal with either the Ohio Board of Tax Appeals (https://www.bta.ohio.gov) or the Trumbull County Court of Common Pleas. You must also file a copy of your appeal notice with the Board of Revision.

What happens at a Board of Revision hearing in Trumbull County?

At a Trumbull County Board of Revision hearing, you present your case to a three-member board consisting of representatives from the County Auditor, Treasurer, and Commissioner's offices. This is a formal quasi-judicial proceeding where you must provide evidence to support your claim that your property is overvalued. You should bring documentation such as recent appraisals, comparable sales data from similar properties, photographs showing property condition or defects, and repair estimates. The burden of proof is on you as the property owner to demonstrate why the assessed value should be reduced. The Board will review your evidence, may ask questions, and can raise, lower, or maintain your property's value based on the evidence presented. Decisions typically take 90 days or longer depending on case volume, after which you'll receive a written decision.

How much can I save by appealing my property taxes in Trumbull County?

The amount you can save by appealing your property taxes in Trumbull County depends on how much your property's assessed value is reduced. Since Trumbull County uses Ohio's 35% assessment ratio, every $10,000 reduction in market value reduces your assessed value by $3,500. With an average effective tax rate of 1.38% in the county, a $10,000 market value reduction would save approximately $48 annually, while a $30,000 reduction would save about $144 per year. If you successfully argue your home's value should be reduced from $180,000 to $150,000 (a $30,000 decrease), your annual tax bill would drop by approximately $144. The actual savings vary based on your property's specific location and the local millage rates that apply to your school district, township, and city. Over multiple years, these savings can add up to thousands of dollars.

What evidence do I need for a Trumbull County property tax appeal to be successful?

To build a strong property tax appeal in Trumbull County, you need concrete evidence that your property's assessed market value is too high. The most persuasive evidence includes a recent professional appraisal showing a lower market value than the county's assessment, comparable sales data from at least three to five similar properties in your neighborhood that sold for less within the past year, and photographs documenting property defects, damage, or unfavorable conditions. You should also gather repair estimates for any significant maintenance issues, documentation of factors that reduce value such as flooding problems or proximity to noise sources, and property records showing any errors in the county's records (such as incorrect square footage or number of bedrooms). Ohio law considers recent arms-length transactions as the best indicator of value, so strong comparable sales are particularly important. The Trumbull County Board of Revision will evaluate all evidence to determine if your property value should be adjusted.

Can I appeal my Trumbull County property taxes every year, or is there a waiting period?

In Ohio, property owners can generally file an appeal every three years for their property valuation, though there are exceptions. The Trumbull County Board of Revision accepts complaints during the annual filing window (January 1 through March 31) for the current tax year. However, if you filed an appeal in a previous year and received a decision, you typically cannot appeal again for the same property for three years unless there has been a significant change such as a countywide reappraisal, a triennial update, new construction, or substantial property damage. Trumbull County conducts full reappraisals every six years with triennial updates at the three-year mark, and these trigger new filing opportunities for all property owners. You can also appeal if the county increases your property value or if there are errors in the property record. It's important to note that while the filing window is annual, your ability to appeal may be restricted by the three-year rule.

What is Trumbull County's property tax assessment ratio and how does it affect my taxes?

Trumbull County uses Ohio's statutory 35% assessment ratio for all real property. This means that property taxes are calculated on 35% of your home's market value, not the full market value. For example, if the Trumbull County Auditor determines your home has a market value of $150,000, your assessed (taxable) value would be $52,500 (35% of $150,000). The local millage rate is then applied to this assessed value to calculate your annual tax bill. If your total millage rate is 80 mills (which equals $80 per $1,000 of assessed value), you would pay $4,200 in annual property taxes ($52,500 × 0.080). Understanding this assessment ratio is crucial when preparing an appeal, because reducing your market value by $30,000 reduces your assessed value by $10,500 (35% of $30,000), which directly impacts your tax liability.
