How to use this calculator
- Select your state to load the effective tax rate (Tax Foundation 2025 median), or enter a custom rate.
- Enter the assessed value of your property (use your county assessor's value, not market value).
- Enter applicable exemptions (homestead, senior, veteran, etc.).
- Optionally add special assessments and a projected annual value increase to see multi-year estimates.
- 2026 note: property taxes are deductible when itemizing, subject to the SALT cap of $40,400 per OBBB §70120.
Formula and assumptions
Property tax in the U.S. is: net taxable value × effective rate. “Net taxable” subtracts any homestead or other dollar exemptions. “Effective rate” is the combined rate from your state, county, school district, and any special districts (Source: Tax Foundation 2025 + state revenue departments).
taxableValue = assessedValue - totalExemptions annualTax = (taxableValue * effectiveRate) + specialAssessments monthlyTax = annualTax / 12 Projection year N: assessedValue_N = assessedValue * (1 + annualValueIncrease%)^N

SALT cap note: in 2026, this $5,363 property tax is deductible as part of the $40,400 SALT cap (OBBB §70120) — but only if you itemize, and only if your combined state/local income + property taxes are below the cap.
Limitations
- Effective rates are state-level averages — your actual rate may differ significantly by county or city.
- Exemption eligibility varies by jurisdiction — confirm locally.
- Assessment ratio (assessed vs. market value) varies by jurisdiction and is not modeled separately.
- Mello-Roos and other special assessments must be entered manually.
- Educational estimate only — contact your county assessor for actual bill.
