What is a property tax appeal?

A property tax appeal is a formal challenge to the assessed value of your property as determined by your local tax assessor. If your property is overassessed, you may be paying more in property taxes than you legally owe.

How to appeal your property tax assessment

Review your assessment notice carefully

Research comparable property values in your neighborhood

Gather evidence: recent appraisals, comparable sales, photos of damage

File an appeal with your local Assessment Review Board before the deadline

Attend the hearing and present your evidence

Important deadlines

Property tax appeal deadlines are strict and vary by state — typically between 30 and 90 days from when you receive your assessment notice. In many states, the deadline is May 15 or within 30 days of the assessment notice. Missing this deadline usually means waiting until next year.

Grounds for a property tax appeal

1

The assessed value is higher than your property’s actual market value
2

Errors in property description (wrong size, number of bedrooms, lot size)
3

Comparable properties in your area are assessed at lower values
4

Recent damage or deterioration not reflected in the assessment
5

Incorrect exemptions not applied (senior, veteran, homestead)

Property / Tax Appeals in Oklahoma

Property owners in Oklahoma may find themselves disagreeing with their property tax assessments. An accurate assessment is crucial, as it directly impacts your tax liability. Fortunately, Oklahoma law provides a clear process for appealing property valuations. Understanding these procedures and deadlines is essential to ensure you pay a fair amount. This guide will help you navigate the property and tax appeal process in Oklahoma.

Property tax appeals in Oklahoma are governed by **Title 68 of the Oklahoma Statutes**, specifically **§68-2877**, which outlines the appeal process from the County Assessor to the County Board of Equalization. The **Oklahoma Tax Commission (OTC)** provides oversight and forms for these appeals. For properties valued over $3,000,000, appeals may go to the Court of Tax Review. Recent updates, such as those in **2026**, emphasize strict adherence to filing deadlines to preserve appeal rights, ensuring fairness in Oklahoma’s property tax system.

To initiate an appeal, first file an informal protest with your **County Assessor**. If unresolved, you can file a formal appeal with the **County Board of Equalization** using **Form 976**. The County Assessor’s office can be contacted for specific local procedures and forms. For example, the **Oklahoma County Assessor** can be reached at **(405) 713-1200**. The **Oklahoma Tax Commission** also offers resources and guidance, and their general inquiry line is **(405) 521-3160**.

The appeal process typically begins with an informal protest to the County Assessor, followed by a formal appeal to the County Board of Equalization if necessary. You must file a written protest within 30 days of the Notice of Valuation. Provide strong evidence supporting your claim, such as comparable sales or independent appraisals. Most property tax appeals are resolved within 60 to 120 days. Use the petition generator above to create an appeal letter in under two minutes.
