The Equity Argument in Property Tax Appeals: How to Use It Effectively
TL;DR
If similar homes in your neighborhood are assessed at lower values, you have an equity (or uniformity) argument. This is separate from a market value argument. Pull assessment records for 5-10 comparable properties nearby and show that your per-square-foot assessed value is higher than the neighborhood average. Many states specifically allow equity-based appeals. This argument works even when comparable sales support the assessor's value, because it focuses on fairness among similar properties.
What Is an Equity Argument?
Most state constitutions require that similar properties be assessed uniformly. If your home is assessed at $350,000 but three nearly identical homes on your street are assessed at $300,000-$310,000, your assessment is inequitable. You are paying more than your fair share of taxes relative to your neighbors.
The equity argument does not ask whether your assessed value matches market value. It asks whether your assessed value is consistent with assessments of similar properties. These are two different legal questions.
When to Use the Equity Argument
The equity argument is most effective when:
- Your home's per-square-foot assessment is higher than similar nearby homes
- Comparable sales actually support the assessor's value (making a market value argument weak)
- A recent reassessment raised your value significantly more than your neighbors
- New construction in your area was assessed at a different rate than existing homes
- Your state specifically allows equity-based appeals
How to Build the Equity Case
Step 1: Identify Comparable Properties
Find 5-10 properties in your neighborhood that are similar to yours in size, age, style, and features. These do not need to have sold recently. You are comparing assessments, not sale prices.
Step 2: Pull Assessment Records
Get the current assessed value for each property. Most county assessor websites let you search by address. Record the assessed value, square footage, lot size, and property characteristics for each.
Step 3: Calculate Per-Square-Foot Values
| Property | Assessed Value | Sq Ft | $/Sq Ft |
|---|---|---|---|
| Your home | $350,000 | 1,800 | $194 |
| 123 Oak St | $305,000 | 1,750 | $174 |
| 456 Elm Ave | $310,000 | 1,820 | $170 |
| 789 Pine Dr | $308,000 | 1,780 | $173 |
| 321 Maple Ln | $312,000 | 1,800 | $173 |
| Neighborhood avg | $309,000 | 1,790 | $173 |
In this example, your home is assessed at $194/sqft while the neighborhood average is $173/sqft. That is a 12% premium with no justification.
Step 4: Present the Disparity
Show the board that your assessment is an outlier. Calculate the percentage by which your assessment exceeds the neighborhood average. Request a reduction to bring your assessment in line.
States That Specifically Allow Equity Appeals
Many states have laws requiring uniform assessment. In these states, you can appeal solely on equity grounds even if the market value supports the assessment:
- Texas (unequal appraisal protest)
- Illinois (uniformity complaint)
- Georgia (uniformity argument)
- Michigan (equalization)
- Ohio (equity claim to Board of Revision)
- New York (unequal assessment)
Check your state's property tax code for uniformity or equity provisions.
Combining Equity and Market Value Arguments
The strongest appeals use both arguments: "My assessment exceeds market value based on comparable sales, AND it exceeds the assessments of similar properties in my neighborhood." This gives the board two independent reasons to grant a reduction.
