1. What is Property Tax?
Property tax is an ad valorem tax (based on value) paid by an individual or other legal entity on real estate or other types of property. It is typically a local tax imposed by counties, cities, or school districts to fund public services.
Where Does the Money Go?
Property taxes generally fund local services such as:
- Public schools and education
- Police and fire departments
- Road maintenance and construction
- Libraries and parks
- Water and sewer systems
- Local government administration
2. How Property Tax is Calculated
The basic formula for property tax is simple, but the components can be complex:
Property Tax = Assessed Value × Tax Rate
Key Components:
1. Assessed Value
The dollar value assigned to your home by a public tax assessor for taxation purposes.
- Often a percentage of market value (e.g., 80% or 100%)
- Reassessed periodically (annually, every 3 years, etc.)
- Based on sales of comparable homes, improvements, and location
2. Tax Rate (Mill Rate)
The rate at which your property is taxed.
- Often expressed in "mills"
- 1 Mill = $1 of tax for every $1,000 of assessed value
- Example: 25 mills = 2.5% tax rate
Calculation Example:
Market Value: $500,000
Assessment Ratio: 80% (Assessed Value = $400,000)
Mill Rate: 20 mills ($20 per $1,000)
Tax = ($400,000 ÷ 1,000) × 20 = $8,000

7. How to Lower Your Property Tax
Think your tax bill is too high? Here are actionable steps to potentially lower it:
-
Review Your Property Card:
Check for errors in the assessor's description (e.g., wrong square footage, wrong number of bathrooms). Errors are common!
-
Check Comparable Sales (Comps):
If similar homes in your neighborhood sold for less than your assessed value, you may have grounds for an appeal.
-
Apply for All Exemptions:
Ensure you are claiming every exemption you qualify for (Homestead, Senior, etc.). They are not automatic; you must apply.
-
File an Appeal:
Most jurisdictions have an appeals window (often 30-90 days after assessment). Prepare evidence (photos, comps, contractor estimates for repairs) and present your case.
-
Don't Over-Improve:
Major renovations increase assessed value. Understand the tax implications before building that pool or addition.
