What Is Property Tax?
Property tax is an ad valorem tax levied by local governments on real estate. It is typically based on the assessed value of the property and is used to fund public services such as schools, police, fire departments, roads, and infrastructure. In the United States, property taxes are administered at the county and municipal levels, with rates varying significantly by location.
How Property Tax Is Calculated
Property tax is calculated using the following formula:
Property Tax = Taxable Value × Tax Rate
Taxable Value = (Assessed Value × Assessment Ratio) − Exemptions
Key Components
- Assessed Value: The value determined by the local tax assessor, often a percentage of market value.
- Assessment Ratio: The percentage of market value used for assessment (100% in many states).
- Tax Rate: Expressed as a percentage or in mills (1 mill = $1 per $1,000 of assessed value).
- Exemptions: Reduce the taxable value (homestead, senior, veteran, disabled).

❓ Property Tax Calculator FAQ
What is the average property tax rate in the US?
The national average effective property tax rate is approximately 1.10% of a home's assessed value. However, rates vary significantly by state, from under 0.30% in Hawaii to over 2.50% in New Jersey.
How is property tax calculated?
Property tax is calculated by multiplying the taxable value of your property by the local tax rate. The taxable value is the assessed value minus any applicable exemptions (homestead, senior, veteran, etc.).
What is a mill rate?
A mill rate is another way to express property tax rates. One mill equals $1 of tax per $1,000 of assessed value. For example, a mill rate of 10 means you pay $10 per $1,000 of value, which is equivalent to a 1.0% tax rate.
What is a homestead exemption?
A homestead exemption reduces the taxable value of a primary residence. Many states offer this exemption to lower the tax burden on homeowners. The amount varies by state and local jurisdiction.
What is an assessment ratio?
The assessment ratio is the percentage of a property's market value that is used for tax assessment purposes. In many states, properties are assessed at 100% of market value, but some states use a lower ratio (e.g., 50% or 80%).
How do senior exemptions work?
Senior exemptions provide additional property tax relief for homeowners aged 65 and older. The exemption amount and eligibility criteria vary by state and local jurisdiction. Some states also have income limits for this exemption.
What is the difference between assessed value and market value?
Market value is the estimated price a property would sell for in the current market. Assessed value is the value determined by the local tax assessor for tax purposes, which may be a percentage of market value (determined by the assessment ratio).
How often are property taxes assessed?
Most jurisdictions reassess property values annually or every few years. Some states have caps on how much assessed values can increase each year (e.g., California's Proposition 13).
Can I appeal my property tax assessment?
Yes, most jurisdictions allow homeowners to appeal their property tax assessment if they believe it is inaccurate. The appeals process varies by location and typically involves providing evidence of the property's fair market value.
What are special assessments?
Special assessments are additional taxes levied on properties to fund specific projects or services, such as road improvements, sidewalk construction, or utility upgrades. These are typically separate from general property taxes.
How do property taxes affect mortgage payments?
Many mortgage lenders include property taxes in your monthly escrow payment. The lender collects the tax amount each month and pays the tax bill on your behalf when it's due. This helps ensure that taxes are paid on time.
Are property taxes deductible on federal taxes?
Yes, property taxes are deductible on federal income tax returns, subject to the SALT (State and Local Tax) deduction limit of $10,000 per year ($5,000 for married filing separately). This applies to state and local property taxes combined.
