Frequently asked questions
Is assessed value the same as market value?
No. Assessed value is set by the local assessor and may be a fraction of market value, depending on jurisdiction. Some areas use full market value; others use a ratio.
What is a mill rate?
A mill rate is the tax per 1,000 units of assessed value. A rate of 20 mills means 20 per 1,000, or 2% of assessed value.
Are exemptions included?
No. Homestead, senior, veteran, or disability exemptions reduce the taxable base before the rate is applied. Apply them manually before using the calculator.
Why does my bill differ from neighbors?
Even on similar properties, bills vary due to assessment date, exemptions, special districts, and any caps or limits on annual increases.
Can I appeal my assessment?
Most jurisdictions allow appeals if you believe the assessed value is too high. Deadlines and procedures vary; check your local assessor's website.

Frequently asked questions
What is the difference between assessed value and market value?
Market value is what a property would sell for. Assessed value is the value assigned by your local assessor for tax purposes — often a percentage of market value called the assessment ratio. The tax is applied to the assessed value.
What is a mill rate?
A mill rate (or millage) is the tax rate expressed per $1,000 of assessed value. A rate of 20 mills means $20 per $1,000, or 2% of assessed value. Some calculators use mills; others use a direct percentage.
How do I find my local property tax rate?
Your county assessor's office or municipal website lists the current mill rate. Your annual property tax bill also shows the rate applied to your property.
Are property taxes deductible?
In the US, property taxes on your primary residence may be deductible under the SALT deduction, currently capped at $10,000 per year for federal returns. Check current IRS guidance and consult a tax professional.
Can property tax estimates be used for home budgeting?
Yes. Property tax adds significantly to monthly homeownership cost. Divide the annual estimate by 12 and add it to your mortgage payment, insurance, and maintenance budget for a realistic total cost of ownership.

How are property taxes calculated step by step?
Step 1: Determine the assessed value — your local assessor multiplies the market value by the assessment ratio (e.g. 80%). Step 2: Subtract any exemptions (homestead, senior, veteran, disability). Step 3: Apply the mill rate: (taxable assessed value ÷ 1,000) × mills. For example, a $300,000 home assessed at 80% ($240,000), with a $25,000 homestead exemption ($215,000 taxable), at 18 mills produces $3,870 in annual property tax.
Can I appeal my property tax assessment?
Yes — most jurisdictions allow homeowners to appeal their assessed value within a fixed window after assessment notices are mailed, typically 30–90 days. Grounds for appeal include: the assessed value exceeds market value, comparable properties are assessed lower, or factual errors (wrong square footage, bedroom count, lot size). Evidence is key — bring recent comparable sales and a formal appraisal if possible. Successful appeals can reduce tax bills by hundreds or thousands per year.
What are homestead exemptions and how much do they save?
A homestead exemption reduces the taxable assessed value of a primary residence. Texas exempts $100,000 from school district taxes (post-2023 legislation). Florida offers $50,000 for most homeowners. California's Proposition 19 offers a $7,000 exemption on assessed value. The dollar savings depend on the local mill rate — a $50,000 exemption at 15 mills saves $750/year. Additional exemptions for seniors, veterans, and low-income households vary widely by county.
Real-world scenarios
Estimating property tax before making an offer on a home
Enter the asking price, your state's typical assessment ratio, and the county mill rate (available on the county assessor website). Subtract any exemptions you qualify for. Divide the annual result by 12 to see the monthly tax obligation — this amount is typically escrowed into your mortgage payment. A $450,000 home in a county with a 1.8% effective tax rate adds $675/month to your housing cost before insurance or HOA.
Comparing property tax burden across states
Use the state-specific calculators (TX, CA, FL, NY, NJ) to compare the same home value across different states. A $400,000 home in New Jersey (effective rate ~2.2%) generates roughly $8,800/year in property tax. The same home in Florida (effective rate ~0.83%) generates about $3,320/year — a $5,480 annual difference. This gap often factors into retirement relocation decisions and total cost-of-living comparisons.
Budgeting property tax for a newly purchased home
The prior owner's tax bill may not reflect what you will owe — especially in states like California where reassessment occurs at sale, or in any market where you paid significantly above the previous assessed value. Always calculate your estimated tax using the purchase price as the base market value, not the seller's prior bill. Many buyers are surprised to find their annual tax is 30–50% higher than what the seller was paying.
