If you think your property in Trumbull County, Ohio, is overvalued for taxes, you can file a complaint. Use the Standard Form DTE 1 to start a legal challenge through the Trumbull County Board of Revision (BOR). This could lead to lower property taxes. This guide will help you through the process, including recent updates and best practices.

Preparing well is key to a successful complaint. This guide is for homeowners, business owners, or anyone representing a property. It covers everything from understanding the DTE 1 form to the Board of Revision hearing.

What is the DTE 1 Form?

The DTE 1 form is for challenging the county auditor’s property value in Trumbull County. It helps ensure your property’s taxable value is fair. This affects how much you pay in property taxes.

When you file a DTE 1, you must prove your case. The Trumbull County BOR reviews these complaints. They decide if the property value should be adjusted.

Why File a DTE 1 Complaint?

Property values in Trumbull County are updated every three years and every six years. The 2023 reappraisal changed tax bills for 2024. If you think your property value is too high, filing a DTE 1 can help lower your taxes.

Common reasons to file include:

Who Can File a DTE 1 Complaint?

In Trumbull County, you can file a DTE 1 complaint if you are:

  • A property owner or their spouse.
  • A professional like a real estate appraiser or accountant.
  • An officer or employee of a company owning the property.

You must explain your connection to the property and provide contact info. This ensures the BOR can reach you.

Filing Deadlines and Recent Updates for 2025

The filing period for DTE 1 complaints in Trumbull County starts January 2, 2025 and ends March 31, 2025. You must file by March 31 or the first half tax deadline. A postmark or County Auditor’s stamp proves you filed on time.

Recent changes to the DTE 1 process include:

  • Electronic Filing Option: Now, you can file complaints online through the Trumbull County Auditor’s website. This way, you don’t need a notary if you submit it digitally.
  • 2023 Reappraisal Impact: The 2023 reappraisal by contracted appraisers has led to big changes in property values. This is because of the rising market values, causing more people to file complaints.
  • Informal Hearings: From October 30 to November 3, 2023, you can have informal hearings. These are to discuss the 2023 values before you formally file. But, these hearings don’t replace the DTE 1 process.

How to File a DTE 1 Complaint in Trumbull County

Filing a DTE 1 complaint has several steps. Here’s a detailed guide to help you follow the rules and increase your chances of success.

Step 1: Obtain the DTE 1 Form

The DTE 1 form is available in two ways:

  • Digital Form: You can download it from the Trumbull County Auditor’s website (auditor.co.trumbull.oh.us) or the Ohio Department of Taxation website (tax.ohio.gov).
  • Standard Form: You can get it in person at the Trumbull County Auditor’s Office or by calling (330) 675-2420.

Make sure to use the latest version of the form, updated for 2025. This will help avoid any issues.

Step 2: Complete the Form Accurately

The DTE 1 form needs specific information, including:

  • Owner of Record: The name of the property owner as shown on the deed.
  • Parcel Number: The unique number for the property, found on tax bills or the auditor’s website.
  • Complainant’s Information: Your name, how you’re related to the property, and your contact details.
  • Opinion of Value: Your suggested fair market value, backed by evidence.
  • Reason for Complaint: A clear reason why you think the current valuation is wrong.

If you’re filling out the form by hand, it needs to be notarized. But, if you’re submitting it digitally, it doesn’t need a notary. Just make sure it’s complete and accurate.

Step 3: Gather Supporting Evidence

You need to prove that the assessed value is wrong. Good evidence is key to a successful complaint. Acceptable evidence includes:

  • Recent Sales Data: Documents like purchase agreements, closing statements, or HUD-1 forms for the property or similar ones.
  • Appraisal Reports: A 2023 or 2024 appraisal by a certified appraiser for tax purposes, with the appraiser ready to testify.
  • Income and Expense Statements: For properties that make money, provide detailed financial data for the tax year and two years before.
  • Property Condition Documentation: Photos, repair estimates, or records of any changes to the property (like damages or demolitions).

Step 4: Submit the Complaint

After filling out the DTE 1 form and gathering evidence, submit it to the Trumbull County Auditor’s Office by March 31, 2025. You can do this in a few ways:

  • In-Person: At 160 High Street NW, Warren, OH 44481.
  • Mail: Send it via certified mail to prove you filed it.
  • Email: If you’re submitting a digital form, you can email it through the auditor’s website.

If your contact information changes after filing, update it. This way, you won’t miss any BOR notices.

Step 5: Prepare for the Board of Revision Hearing

After filing, the BOR will set a hearing date. This can last 15 minutes for homes and 20-30 minutes for businesses. Key points:

  • Hearing Process: The person who filed will share their case. This includes evidence and their story. Witnesses are sworn in, and everything is recorded.
  • Attendance: It’s best to be there to answer questions. If you’ve submitted an appraisal, the appraiser must be there too.
  • Rescheduling: You can ask for one reschedule for a good reason. But, asking again might mean your case is dismissed.

The BOR might change the value, keep it the same, or raise it based on what you provide.

Step 6: Await the Decision

The BOR usually makes a decision in 2-3 weeks. They send it by certified mail or email. If they agree, the new value will be used for that year and maybe the next. If they say no, you can appeal to the Ohio Board of Tax Appeals within a short time.

Key Considerations for a Successful DTE 1 Filing

To make your case stronger, remember these tips:

  • Accuracy is Critical: If your form is wrong or missing info, it might get thrown out. Make sure everything is right before you send it.
  • Evidence is King: The BOR looks at your evidence a lot. This could be recent sales or appraisals to show the property’s value.
  • Legal Representation: You don’t have to have a lawyer or appraiser. But, they can help, even with tricky cases.
  • Understand Limitations: The BOR can change property values. But, they can’t change tax rates or how much you pay in taxes. Those are set by voters.

Trumbull County Valuation Process: How It Works

The Trumbull County Auditor’s Office updates property values every three years. This is because of Ohio Revised Code (ORC) Section 5713.01. Here’s how it works:

  • Triennial Updates: Values are updated every three years to keep up with the market.
  • Sexennial Reappraisals: Every six years, there’s a big update. The last one was in 2023.
  • Market-Based Valuation: Values are based on recent sales, location, and property details like size and condition.

The 2023 reappraisal looked at every property’s outside. This led to big increases in value because of a strong market. Property taxes are based on 35% of the appraised value.

Impact of Valuation Changes on Property Taxes

The BOR adjusts property values but doesn’t control tax rates. Tax rates are set by voter-approved levies and inside millage (up to 10 mills). A successful DTE 1 complaint can lower your assessed value, reducing your tax bill. Yet, tax increases can happen due to new levies or changes in inside millage.

For example, if your property’s assessed value drops from $200,000 to $180,000, and the tax rate is 50 mills, you save:

  • Original Tax: $200,000 × 0.35 × 0.050 = $3,500
  • New Tax: $180,000 × 0.35 × 0.050 = $3,150
  • Savings: $3,500 – $3,150 = $350 per year
