Property Information

Understanding property tax

Local governments fund schools, roads, and services partly through property tax. Your bill depends on how the assessor values your home and the tax rates voters and officials set in your area.

Annual tax = (Property value − Exemptions) × Rate ÷ 100
Monthly tax = Annual tax ÷ 12

What is property tax?

Property tax is a local levy on real estate, usually calculated from assessed value multiplied by tax rates set by counties, cities, school districts, and special districts. It funds schools, roads, emergency services, and other municipal programs.

Your bill depends on how the assessor values the property, which exemptions you qualify for, and combined millage or percentage rates in your jurisdiction—not simply what a home listed for on a real estate site.

Formula

Taxable value = max(0, Property value − Exemptions)

Annual tax = Taxable value × (Rate ÷ 100)

Monthly tax = Annual tax ÷ 12

Effective rate = (Annual tax ÷ Property value) × 100

Worked examples

Suburban home with homestead exemption

Value $350,000 · Rate 1.2% · Exemptions $25,000

Annual $3,900 · Monthly $325

($350,000 − $25,000) × 0.012 = $3,900/year. Budget ~$325/month for escrow—not including insurance or HOA.

Higher-rate jurisdiction

Value $280,000 · Rate 2.1% · Exemptions $0

Annual $5,880 · Monthly $490

No exemption: $280,000 × 0.021 = $5,880/year. Effective rate equals nominal rate when exemptions are zero.

Recently purchased home (reassessed)

Value $520,000 · Rate 1.05% · Exemptions $40,000

Annual $5,040 · Monthly $420

After purchase, assessed value may match sale price. ($520,000 − $40,000) × 0.0105 = $5,040/year—compare to what the seller paid at a lower assessment.

Condo with lower rate, no exemption yet

Value $195,000 · Rate 0.95% · Exemptions $0

Annual $1,852.5 · Monthly $154.38

Smaller value but still verify whether HOA fees cover any community taxes separately from this estimate.

Senior exemption scenario

Value $410,000 · Rate 1.35% · Exemptions $75,000

Annual $4,522.5 · Monthly $376.88

Larger exemption reduces taxable base to $335,000. Confirm senior exemption filing deadlines with your assessor—amounts are illustrative.

Common mistakes

Using Zestimate instead of assessed value

Listing sites show market estimates; tax bills follow assessor rules. Use your assessment notice when available.

Forgetting special district levies

School bonds and municipal districts add to the headline rate. A 1% base rate plus 0.3% in districts is 1.3% combined.

Assuming exemptions apply automatically

Homestead and other exemptions usually require an application. Until approved, budget without them.

See yearly tax and a monthly figure for budgeting.

Exemptions

Pro Tips

  • Check your county assessor site for official rates and exemption forms

  • Appeal the assessment if comparable homes are taxed lower

Frequently Asked Questions

How does this estimator calculate tax?
Taxable value = property value minus exemptions (not below zero). Annual tax = taxable value × (rate ÷ 100). Monthly tax = annual ÷ 12. Effective rate = annual tax ÷ full property value × 100.
What tax rate should I enter?
Use the combined effective rate for your jurisdiction—county, city, school district, and special levies. U.S. effective rates often fall roughly between 0.5% and 2.5% of value but vary widely. Your assessor or last tax bill is the best source.
Assessed value vs market value?
Tax bills usually use assessed value, which may differ from sale price. Some states apply an assessment ratio (e.g., a fraction of market value). Enter what you know and confirm with your county assessor.
What exemptions can I include?
Enter total dollar reductions you qualify for—homestead, senior, veteran, or disability exemptions where offered. Rules and amounts differ by state and county.
Does this include all local fees?
No. Special assessments, Mello-Roos, stormwater fees, and bond measures may appear on real bills but are not modeled unless you fold them into your rate manually.
How do I find my local property tax rate?
Check your county assessor or tax collector website, your most recent tax bill, or your closing disclosure if you recently bought. Many counties publish millage rates or an effective rate calculator.
Why did my tax jump after buying a home?
Purchases can trigger reassessment to market value in some jurisdictions. Exemptions may reset until you file homestead paperwork. Run before-and-after scenarios with this tool.
Can I deduct property tax on my federal return?
Itemizers may deduct state and local property taxes subject to federal SALT limits and current IRS rules. This varies by filing status and tax year—consult a tax professional.
What is an effective tax rate?
Effective rate = annual tax ÷ full property value. It helps compare homes in different counties even when nominal millage rates look similar.
Is this tax or financial advice?
No. This is a simplified budgeting calculator. For appeals, deductions, or investment decisions, consult your county assessor or a qualified tax professional.
