How US Property Taxes Work: Assessment, Rates, and Exemptions

Property tax is the primary funding mechanism for local governments—school districts, fire departments, road maintenance, and parks are largely financed through property tax revenues. Unlike federal income tax, property tax is entirely local: rates, assessment methods, and exemptions vary by county and city, not just by state.

📊 Three-Step Calculation: How Your Bill Is Determined

Step 1: Market Value What your property would sell for in the open market. County assessors typically derive this from comparable recent sales (comps) and periodic on-site assessments.

Step 2: Assessed Value Many jurisdictions don't tax at full market value—they apply an assessment ratio: > Assessed Value = Market Value × Assessment Ratio

Assessment ratios vary: California assesses at 100% of purchase price (but limits annual increases to 2% under Proposition 13), while some Texas counties assess at 60–80%.

Step 3: Millage Rate The tax rate, expressed in "mills" where 1 mill = $1 per $1,000 of assessed value. A millage rate of 15 mills on $400,000 assessed value = $6,000 annually. > Annual Tax = Assessed Value × (Millage Rate ÷ 1,000)

Local millage rates are published by your county appraisal district and often searchable online.

🏠 Exemptions That Reduce Your Tax Bill

Homestead Exemption (Most Common) If you own and occupy your home as a primary residence, most states reduce your taxable value. Examples:

• Florida: First $50,000 of assessed value exempt for homesteads; additional $25,000 for non-school taxes
• Texas: $40,000 homestead exemption from school district taxes (plus age 65+ exemption)
• California (Prop 13): Annual assessment increase capped at 2% regardless of market appreciation—a massive long-term benefit for longtime homeowners

Senior Citizen Exemptions Most states offer additional reductions for homeowners 65+. Some "circuit breaker" programs cap property taxes as a percentage of income for seniors.

Veterans / Disability Exemptions Veterans with service-connected disabilities often receive partial or full property tax exemptions. Rules vary significantly by state and disability rating.

Agricultural Land Farmland is assessed at agricultural use value—far below market value—in most states.

💰 Property Taxes and Your Mortgage (Escrow)

If you have a mortgage, your lender almost certainly requires an escrow account for property taxes. You pay 1/12 of the estimated annual tax each month alongside principal and interest, and the lender pays the bill when due.

Your total monthly payment = PITI:

• Principal
• Interest
• Taxes (escrowed property tax)
• Insurance (homeowners insurance)

If your property tax bill increases (reassessment, exemption removal, rate increase), your lender adjusts your monthly escrow payment at annual review. Budget for potential increases in high-growth markets where assessed values are catching up to market prices.

📝 How to Appeal Your Property Assessment

If you believe your home is over-assessed, you have the right to challenge it:

1. Review your annual assessment notice (mailed by your county assessor) 2. Research comparable recent sales in your immediate neighborhood (within 0.5 miles, similar size/age) 3. File an appeal with your local assessment appeal board within the specified window (typically 30–90 days from notice) 4. Present evidence: recent comps, independent appraisal, photos of condition issues 5. Attend hearing or submit written appeal

A successful reduction of $100,000 in assessed value at a 2% effective rate saves $2,000/year permanently until the next reassessment.
