Property taxes are the primary source of revenue for local governments, funding schools, roads, public safety, and other services. Because the tax bill depends on the assessed value of the property, owners who believe their assessment is too high have a right to challenge it. Paralegals who work in real estate, tax, or commercial litigation often help prepare these appeals, and the topic is an important part of real property coverage on paralegal exams.

How Property Tax Works

A property tax is an ad valorem tax, meaning it is based on value. The basic calculation is straightforward: the assessed value is multiplied by the tax rate, often expressed as a millage rate or rate per hundred dollars. Local officials, commonly called assessors, determine the assessed value. Taxing bodies such as counties, school districts, and municipalities set the tax rates through budgeting processes.

Assessed value may differ from market value. Some jurisdictions assess at one hundred percent of fair market value, while others apply an assessment ratio, such as thirty five percent of market value. Understanding the local ratio is essential before deciding whether an assessment is excessive.

Methods of Valuation

Assessors typically rely on three accepted approaches to value.

Sales Comparison Approach

This approach compares the subject property to recent sales of similar properties nearby, with adjustments for differences in size, age, condition, and features. It is the most common method for residential property.

Cost Approach

The cost approach estimates what it would cost to rebuild the improvements, subtracts depreciation, and adds the value of the land. It is useful for new construction and special purpose buildings that rarely sell.

Income Approach

For commercial properties such as apartment buildings and office space, value is estimated based on the income the property generates. Net operating income is divided by a capitalization rate to arrive at value. Small changes in the capitalization rate can produce large changes in value, so this is often a point of dispute.

Exemptions and Special Assessments

Many states offer exemptions that reduce taxable value or tax liability. Common examples include homestead exemptions for primary residences, exemptions for seniors, veterans, and persons with disabilities, and exemptions for property owned by religious, charitable, or educational organizations. Agricultural land may qualify for use value assessment, which taxes the land based on its farming value rather than its development potential. Paralegals should note that exemptions typically require timely applications and annual renewals.

Special assessments are different from general property taxes. They are charges levied against properties that benefit from a specific local improvement, such as new sidewalks or sewer lines, and are based on the benefit to the property rather than its overall value.

Grounds for Appeal

An owner may challenge an assessment on several grounds.

Overvaluation: the assessed value exceeds fair market value or the legally required percentage of it.
Unequal treatment: similar properties are assessed at lower values, violating uniformity requirements.
Factual errors: incorrect square footage, number of bedrooms, lot size, or condition.
Improper classification: the property is placed in the wrong class, such as commercial instead of residential.
Denial of an exemption for which the owner qualifies.
Illegal or unauthorized tax, which may raise questions of law.

The Appeals Process

Step 1: Review the Notice and Deadlines

Deadlines are strict and often short, sometimes thirty days from the date of the assessment notice. A missed deadline can bar the appeal for that year. Paralegals should calendar every date as soon as the notice arrives.

Step 2: Informal Review

Many assessors will meet informally to review errors or consider evidence. Correcting a simple data error at this stage can resolve the dispute without a formal hearing.

Step 3: Board of Review or Equalization

If the informal review fails, the owner files a petition with the local board. The petition typically includes the parcel number, the owner's opinion of value, and the grounds for appeal. At the hearing, the owner presents evidence, and the assessor defends the valuation. The assessment is often presumed correct, so the owner carries the burden to show error.

Step 4: State Tax Tribunal or Court

A party dissatisfied with the board's decision may appeal to a state tax tribunal, a county court, or another designated forum. These proceedings can be more formal and may involve expert appraisal testimony. Further appeals to appellate courts are generally limited to questions of law.

Evidence a Paralegal Can Help Gather

A recent independent appraisal of the property.
Comparable sales data with dates, prices, and descriptions.
Photographs documenting condition problems or defects.
Repair estimates and inspection reports.
For income property, rent rolls, operating statements, and vacancy data.
The property record card from the assessor showing the data used for valuation.
Purchase closing statements, which can be strong evidence of market value if the sale was recent and at arm's length.

Consequences of Nonpayment

Unpaid property taxes become a lien on the property that is generally superior to most other liens, including mortgages. If taxes remain unpaid, the local government can sell a tax lien certificate or conduct a tax sale. Owners may have a statutory redemption period to reclaim the property by paying the taxes, interest, and costs. Some jurisdictions require payment of the undisputed amount while an appeal is pending, so paralegals should check local requirements.

Frequently Asked Questions

Can an appeal increase my assessment?

In some jurisdictions, the board can raise as well as lower the value on review. Attorneys should evaluate that risk before filing.

How often are properties reassessed?

It varies. Some places reassess annually, others every few years, and some only upon sale or new construction.

Do I need an attorney to appeal?

Individuals can often appeal on their own, but corporations and LLCs may be required to appear through counsel. Complex commercial appeals are best handled by attorneys with appraisal experts.

Does a purchase price control the assessed value?

It is strong evidence of market value, but not always conclusive. Some states use the purchase price as a starting point for the following assessment.
