Property Tax

How property tax works

The basic mechanic:

1. Local government assesses property value through periodic appraisals.
2. Tax rate (mill rate) is applied to assessed value.
3. Property owner receives bill annually or in installments.
4. Failure to pay can lead to tax liens and eventually foreclosure.

Different from federal taxes — property tax is local. Rates and assessment methods vary widely by state and locality.

Property tax variation

Wide range across US:

• Highest — New Jersey, Illinois, New Hampshire (effective rates 2-2.5% of value).
• Lowest — Hawaii, Alabama, Louisiana (under 0.5%).
• Within states — varies by county, city, school district.

These differences add up. A $400K home can have annual tax of $1,500 in low-tax areas vs. $10,000 in high-tax areas.

What property taxes fund

Typical uses:

• Public schools — often the largest portion.
• Police and fire services.
• Local roads and infrastructure.
• Parks and recreation.
• Local government operations.
• Water and waste systems.

Property tax is the primary funding source for most US local governments and schools.

How assessment works

The process:

• Periodic appraisal by local assessor — varies by jurisdiction (annually, every few years, every reassessment cycle).
• Methods — sales comparable, cost approach, income approach.
• Some states have rules limiting annual assessment increases (California's Prop 13 caps at 2%/year).
• Appeals process allows property owners to challenge assessments.

Assessed value often differs from market value. In growing markets, assessments can lag.

Property tax in mortgage payments

For most mortgage holders:

• Lender escrows property taxes — collects monthly along with mortgage payment.
• Lender pays taxes when due.
• Annual review adjusts escrow amount.
• "PITI" payment — Principal, Interest, Taxes, Insurance.

This bundles property tax into monthly housing cost.

Property tax and tax deductions

US tax treatment:

• State and local tax (SALT) deduction allows itemizers to deduct property tax.
• Capped at $10,000 total SALT (combined property + state income/sales tax) since 2017 Tax Cuts and Jobs Act.
• Major impact on high-tax-state homeowners.
• Standard deduction typically better for those with low SALT exposure.

When property tax becomes a problem

A few patterns:

• Rapidly rising values — taxes grow faster than income.
• Fixed-income retirees — property tax can become unaffordable.
• Some states have specific protections — circuit breaker programs, senior exemptions.
• Tax delinquency can lead to tax sale of property.

For households in high-tax areas, property tax can be a significant portion of housing cost.

Property tax appeals

If you believe assessment is too high:

• Review comparable sales in your area.
• Document your home's specifics if reasons exist for lower valuation.
• File formal appeal within deadline.
• Hearing or review process varies by jurisdiction.

Successful appeals can produce meaningful savings. The process varies widely by location.

Property tax in investment property

For real-estate investors:

• Property tax is deductible as business expense.
• Cash-flow analysis must include property taxes.
• Tax variation affects investment yields significantly.
• Local tax trends affect long-term returns.

Property tax is one of the major operating expenses for real-estate investing.

What individuals should know

For homeowners:

• Budget for property tax alongside mortgage.
• Watch assessment notices — appeal if appropriate.
• Understand your jurisdiction's specific structure.
• Consider tax burden in home-buying decisions.

For prospective buyers:

• Effective tax rates vary enormously across locations.
• Total cost of ownership depends heavily on property tax.
• Rapidly appreciating areas may have rapidly rising taxes.

Property tax is a major and often-overlooked component of home ownership. Its variation across locations meaningfully affects total housing costs and investment returns.
