Property Tax in the United States

Property tax in the United States is primarily a local tax levied by counties, municipalities, and school districts. Rates vary from approximately 0.5% to 2.5% of assessed market value, with a national average around 1.1%. Property taxes are a major source of local government revenue.

How Property Tax Works

Property tax is an ad valorem tax (based on value) imposed on real estate. The tax is calculated by multiplying the assessed value of the property by the local millage rate. One mill equals $1 of tax per $1,000 of assessed value.

Property Tax Rates by State

Effective property tax rates vary significantly by state:

• Highest: New Jersey (~2.49%), Illinois (~2.27%), New Hampshire (~2.18%), Texas (~1.80%)
• Lowest: Hawaii (~0.28%), Alabama (~0.41%), Colorado (~0.49%), Louisiana (~0.54%)
• Average: National average approximately 1.1% of home value

Assessment Methods

Property is assessed by the local assessor's office. Common assessment methods include:

• Market Value Approach: Based on recent comparable sales
• Cost Approach: Replacement cost minus depreciation
• Income Approach: Capitalization of net rental income
• Some states assess at a percentage of market value (assessment ratio)

Exemptions and Relief

• Homestead Exemption: Reduces taxable value for primary residences (varies by state)
• Senior Citizen Exemption: Age-based reductions in many states
• Veteran Exemption: Property tax relief for military veterans
• Property Tax Caps: Some states limit annual assessment increases (e.g., California Prop 13)
• Circuit Breaker Programs: Income-based relief for low-income homeowners

Tax Deduction

Property taxes paid on primary and secondary residences are deductible as an itemized deduction on federal tax returns, subject to the $10,000 SALT (State and Local Tax) cap.

Property Tax on Investment Real Estate

Property taxes on rental and investment properties are fully deductible as business expenses against rental income. Commercial property tax rates may differ from residential rates in some jurisdictions.

Appeals Process

Property owners who believe their assessment is too high can appeal to the local assessment appeals board. The process typically involves:

• Reviewing the assessment notice for errors
• Gathering comparable sales data
• Filing a formal appeal with the assessor's office
• Presenting evidence at a hearing
• Further appeal to state tax court if necessary
