Why the same home can cost hundreds more per month in one state than another, how effective property tax rates work, and how to estimate yours.
When buyers compare homes, they usually focus on price and interest rate. Property taxes get less attention, yet they can change your monthly payment as much as a full percentage point on your mortgage rate. And unlike your mortgage, they never go away, even after the loan is paid off.
This guide explains how property taxes work, why they vary so much between states, and how to factor them into what you can afford.
How property taxes work
Property taxes are set locally, by counties, cities, school districts and special districts, and they fund schools, roads, public safety and other services. Your bill is generally your home's assessed value times the local tax rate (sometimes called a millage or mill rate), minus any exemptions you qualify for.
Each of those pieces varies:
- Assessed value may be a percentage of market value and may be updated annually, periodically or only when a home sells, depending on the state.
- Rates differ by jurisdiction, even between neighboring towns.
- Exemptions such as homestead exemptions can reduce the taxable value of your primary residence. Seniors, veterans and people with disabilities often have additional exemptions.
Effective tax rates: the apples-to-apples measure
Because assessment rules vary, the most useful comparison is the effective tax rate: property taxes paid as a percentage of home value. Our state pages calculate it from the U.S. Census Bureau's American Community Survey (median real estate taxes paid divided by median home value).
The spread is wide. Based on that data:
| State | Effective rate | Typical home value (Zillow) | Estimated annual tax |
|---|---|---|---|
| New Jersey | 2.11% | $575,123 | $12,135 |
| Illinois | 2.01% | $295,943 | $5,948 |
| Texas | 1.49% | $296,424 | $4,417 |
| Florida | 0.76% | $375,361 | $2,853 |
| Colorado | 0.48% | $529,013 | $2,539 |
| Hawaii | 0.27% | $832,932 | $2,249 |
State averages hide big local differences, so treat these as starting points. Your county assessor's or treasurer's website will have the actual rates for a specific property.
Worked example: same house, different states
Imagine a $400,000 home with 10% down. At this week's 30-year average of 7.24% (October 29, 2026), principal and interest on the $360,000 loan is $2,453 a month, wherever you buy.
Property taxes change the picture:
- At New Jersey's effective rate of 2.11%: about $703 a month.
- At Texas's 1.49%: about $497 a month.
- At Colorado's 0.48%: about $160 a month.
The monthly difference between the highest and lowest of these is about $543, enough to change how much house you can qualify for. Lenders include property taxes in your housing payment when they calculate your debt-to-income ratio; see our DTI guide.
Property taxes can rise after you buy
When you buy, your tax bill may change. In many places, a sale triggers a reassessment at the purchase price, so the seller's current bill may be lower than yours will be. Ask your agent or the county assessor how reassessment works locally, and estimate taxes on your purchase price rather than the seller's last bill.
Taxes also tend to rise over time as values and budgets grow. Some states cap annual assessment increases for homesteads; others don't. Your state page is a good place to start, and your county's website will have the details.
How property taxes are paid
Most borrowers pay property taxes through an escrow account: the lender collects a portion each month with your mortgage payment and pays the bills when due. If taxes rise, your monthly payment goes up after the servicer's annual escrow analysis. See our escrow and insurance guide.
Special assessments and other local levies
Your tax bill may include more than the base property tax. Some areas add special assessments or district levies for things like new infrastructure, utility districts or local improvements, and these can last for many years. They're often listed separately on the bill. Ask for a copy of the current tax bill for any home you're considering, look at each line, and ask the county or your agent about anything you don't recognize. Your title company can also tell you about recorded assessments.
Tips for buyers
- Look up the actual tax rate for any home you're serious about, not just the state average.
- Apply for your homestead exemption promptly after buying, if your state offers one; there's often a deadline.
- Estimate taxes on your purchase price, especially in places that reassess on sale.
- Compare total monthly cost, not just price, when weighing homes in different towns or states.
- Remember the deduction is limited. Itemizers can deduct state and local taxes, including property taxes, subject to a federal cap; many households take the standard deduction instead. See our mortgage interest and taxes guide.
Common questions
Can I appeal my assessment? In most places, yes. If you believe your assessed value is too high, your county typically has an appeal process with deadlines. Evidence such as recent comparable sales helps.
Do property taxes go away when the mortgage is paid off? No. You'll pay property taxes as long as you own the home. After payoff, you'll pay them directly instead of through escrow.
Are new construction homes taxed differently? Sometimes the first tax bill reflects only the land value, and the next bill jumps once the finished home is assessed. Budget for the full assessed value.
Keeping tax bills and records safe
County bills, homestead filings and assessment notices are documents you will need for years. A home records organizer or a small fireproof document safe keeps tax statements, insurance policies and closing papers protected and findable when escrow asks for them.
