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 Colorado

Property owners in Colorado often face challenges such as unfair property tax assessments, inaccurate property valuations, or denial of tax exemptions. These issues can significantly increase the financial burden on homeowners, making it essential to pursue legal remedies to protect their rights. Under Colorado Revised Statutes § 39-1-104, property owners have the right to appeal their property tax assessments to ensure a fair valuation is applied.

The state of Colorado provides a structured appeals process through county assessment offices and the Board of Assessment Appeals (BAA). For example, Denver County residents can contact the Denver Assessor's Office at (720) 913-1311 to file an appeal or request further information. The 2024-2025 legislative session has also introduced House Bill 24-1103, which aims to streamline the property tax appeal process and enhance transparency for taxpayers.

To initiate an appeal, property owners must submit a formal petition within the stipulated deadlines, supported by evidence such as recent appraisals or comparable property values. Failure to act promptly may result in the forfeiture of the right to challenge an assessment. Colorado’s statutes are designed to balance the interests of taxpayers and local governments, ensuring property taxes reflect accurate market values.
