What Is Board of Equalization
A Board of Equalization is a local government body that reviews property tax assessments to ensure all properties in a jurisdiction are valued fairly and consistently relative to each other. This body exists in most states and counties to correct assessment errors and address systematic inequities across the tax roll.
Unlike an Appraisal Review Board, which focuses on individual property disputes, a Board of Equalization takes a broader view. It can adjust assessments across neighborhoods, property classes, or entire districts to correct assessment ratio problems. If your county assessor systematically undervalued commercial properties by 15% compared to residential properties, the Board of Equalization would address this disparity.
How Boards Function in Practice
Most Boards of Equalization operate on an annual cycle, typically meeting in summer months after assessments are issued but before tax bills go out. Filing deadlines vary by state, but most fall 30-45 days after assessment notices are mailed. Missing this deadline often forecloses your right to appeal that year.
When you file a complaint with the Board, you need to demonstrate that your property's assessment violates the principle of equalization. This means showing that comparable properties in your area were assessed at lower values relative to their market price. For example, if your home was assessed at $450,000 and comparable sales in your neighborhood sold for $400,000-$420,000 in the past year, you have evidence of overvaluation.
The Board examines assessment ratios, which measure the relationship between assessed value and actual market value. Most states target an assessment ratio between 80-100%, meaning assessed value should equal 80-100% of fair market value. If your county's average assessment ratio for similar properties is 95% but yours is 110%, the Board can order a downward adjustment.
Evidence That Wins
- Comparable sales data: Recent arm's length transactions for similar properties within your neighborhood or comparable market area, typically from the past 12 months. Sales must be similar in size, condition, age, and location.
- Assessment discrepancies: Proof that the assessor used incorrect or outdated appraisal methods for your property while using different methods for neighbors. This includes documentation of square footage errors, condition ratings that don't match reality, or missing adjustments for property defects.
- Exemption documentation: If your property qualifies for agricultural, religious, or homestead exemptions that weren't properly applied, the Board can correct this.
- Market analysis reports: Professional appraisals or broker opinions of value that support your position on fair market value.
Common Questions
Can I appeal to the Board of Equalization after the assessment cycle ends? No. The Board's jurisdiction is typically limited to the annual assessment cycle. Once that period closes (usually 60-90 days after assessment notices mail), you lose the right to petition that body for that tax year. However, you may be able to file for the following year's assessment if the overvaluation continues.
What's the difference between filing with the Board of Equalization versus an Appraisal Review Board? If your state has an Appraisal Review Board, you typically file there first for individual property disputes. The Board of Equalization handles broader equity issues and systemic assessment problems affecting multiple properties or classes of property.
Does the Board actually lower assessments, or just hear complaints? Boards of Equalization have real power. They can order assessments reduced, increased, or maintained. Their decisions are binding unless appealed to district court, which is expensive and difficult to win.
