What Is Property Tax?
Property tax is a recurring tax levied by local governments on real estate owners. It is one of the primary funding sources for public schools, road maintenance, police and fire departments, and other local services. The tax is calculated based on the assessed value of your property and the local tax rate set by your county, city, or special district.
Unlike income or sales taxes, property tax is assessed annually and is based on the value of the asset you own rather than your income or spending. This makes it a significant ongoing cost of homeownership that persists for as long as you own the property, regardless of whether your income changes.
Understanding your property tax burden is essential for budgeting, comparing neighborhoods, and evaluating the true cost of a home purchase. Two homes with identical prices in different counties can have very different annual tax bills, directly impacting affordability and monthly housing costs.
How to Use This Calculator
Enter your property's assessed value and the local tax rate (expressed as a percentage or mill rate). The calculator will compute your annual and monthly property tax obligation. You can adjust the tax rate to compare different jurisdictions.
Assessed Value
Enter the assessed value of your property as determined by your local tax authority. This is often different from the market value. Check your most recent property tax bill or assessment notice for the official assessed value. If you only know the market value, multiply it by your area's assessment ratio (commonly 80% to 100% of market value).
Tax Rate
Enter your local property tax rate as a percentage. If your tax authority quotes a mill rate, divide by 10 to get the percentage. For example, a mill rate of 30 equals 3%. You can typically find this rate on your property tax bill or your county's tax assessor website.
Formula
Property tax is calculated using a straightforward multiplication: Annual Property Tax = Assessed Value × Tax Rate. The tax rate is expressed as a percentage of the assessed value and is set annually by local taxing authorities.
To convert a mill rate to a percentage, divide by 10. A mill rate of 20 mills equals 2%. On a property assessed at $250,000, the annual tax would be $250,000 × 0.02 = $5,000. Dividing by 12 gives a monthly payment of approximately $417.
Some jurisdictions apply different rates to different portions of the assessed value, such as a school levy, county levy, and city levy. The effective tax rate is the sum of all these levies. Our calculator uses the combined effective rate for simplicity.
Examples
Example 1: Average Suburban Home
A home in the suburbs with an assessed value of $350,000 and a local tax rate of 1.8% would owe $350,000 × 0.018 = $6,300 per year in property tax. That breaks down to $525 per month, which would be collected through your mortgage escrow account if you have one.
Example 2: High-Tax State
A home in New Jersey with an assessed value of $450,000 and an effective tax rate of 2.5% would owe $450,000 × 0.025 = $11,250 per year. That is $938 per month — nearly double the property tax of a similarly valued home in a low-tax state. This difference can significantly affect monthly housing affordability and long-term ownership costs.
Example 3: Low-Tax State
A home in Hawaii with an assessed value of $600,000 and an effective tax rate of 0.3% would owe $600,000 × 0.003 = $1,800 per year. That is just $150 per month — dramatically less than the New Jersey example despite a higher property value. This illustrates why comparing tax rates is essential when evaluating total housing costs across locations.
Tips
Research Tax Rates Before Buying
Property tax rates vary enormously between counties and even between neighborhoods within the same city. Always check the actual tax rate and assessed value for a specific property before making an offer. Two homes with the same purchase price can have annual tax bills that differ by thousands of dollars.
Factor Tax Increases Into Your Budget
Property taxes can increase over time as assessed values rise or local tax rates change. A home that costs $400 per month in property tax today may cost $600 or more in five years if the area appreciates rapidly. Budget conservatively and assume your tax bill will increase by 2% to 4% annually.
Check for Tax Exemptions
Many jurisdictions offer property tax exemptions for homestead owners, veterans, seniors, and disabled homeowners. These exemptions can reduce your assessed value by $10,000 to $100,000 or more, translating to significant annual savings. File for all exemptions you qualify for as soon as you purchase the property.
Consider the Full Tax Picture
Property tax is just one component of your total housing cost. When comparing locations, factor in property tax alongside homeowners insurance, HOA fees, utilities, and commute costs. A lower property tax rate in one area may be offset by higher insurance or HOA costs.
FAQ
How is property tax calculated?
Property tax is calculated by multiplying your property's assessed value by the local tax rate (also called a mill rate or millage rate). The assessed value is determined by your county or local government and may be lower than the market value. The tax rate varies by jurisdiction and typically includes levies for schools, roads, public safety, and other local services.
What is the difference between assessed value and market value?
Market value is what your home would sell for on the open market. Assessed value is the value your local government assigns for tax purposes, often calculated as a percentage of market value. In some areas, assessed value tracks closely to market value, while in others it may be significantly lower. The assessment ratio varies by state and county.
What is a mill rate?
A mill rate is the amount of tax payable per dollar of assessed value. One mill equals $1 of tax per $1,000 of assessed value. For example, a mill rate of 25 mills means you pay $25 in property tax for every $1,000 of assessed value. On a home assessed at $300,000, that comes to $7,500 per year.
How often is property tax paid?
Property tax is typically paid annually, semi-annually, or quarterly, depending on your jurisdiction. Most mortgage lenders collect property tax as part of your monthly payment through an escrow account, so homeowners often pay monthly even though the tax is billed annually or semi-annually. If you own your home outright, you may pay directly to the county.
What states have the highest and lowest property taxes?
States with the highest property taxes include New Jersey, Illinois, Connecticut, New Hampshire, and Vermont, with effective rates above 2%. States with the lowest property taxes include Hawaii, Alabama, Colorado, Utah, and Tennessee, with effective rates below 0.5%. Rates vary widely even within states, so county-level data matters more than state averages.
Can I appeal my property tax assessment?
Yes, most jurisdictions allow you to appeal your property tax assessment if you believe it is too high. Common grounds for appeal include errors in the property record, comparable sales showing lower value, or recent market declines. The appeal process typically involves filing with a local board of review within a specific deadline, often 30 to 90 days after receiving your assessment notice.
Is property tax deductible?
Property tax is deductible on your federal income tax return if you itemize deductions, subject to the $10,000 state and local tax (SALT) deduction cap. This cap applies to the combined total of state and local income taxes and property taxes. If your total SALT deductions exceed $10,000, you cannot deduct the full amount of your property tax.
Do property taxes increase every year?
Property taxes can increase if your assessed value rises or if local tax rates increase. In rapidly appreciating markets, assessed values may go up significantly, leading to higher tax bills even if the tax rate stays the same. Some jurisdictions have assessment caps that limit annual increases, typically 1% to 3%, but these caps vary by state and may not apply to all properties.
How does property tax affect my monthly mortgage payment?
If your lender requires an escrow account, property tax is included in your monthly mortgage payment. The lender divides your annual tax bill by 12 and adds that amount to your principal, interest, and insurance payment. This means your monthly housing cost is higher than just the loan payment alone, and changes in property tax will cause your monthly payment to adjust.
