Not every state charges property tax the same way, and a few states don't charge it at all
Property tax exists in all 50 states, but Hawaii, Alabama, and Louisiana do not charge a traditional property tax on residential real estate. Instead, they fund schools and local services through other taxes — sales tax, income tax, or business taxes. Even in states that do charge property tax, the rate and what gets taxed varies enormously. A house worth $300,000 might cost you $3,000 a year in property tax in one state and $9,000 in another.
The reason for these differences is that property tax is a local tax, not a federal one. Each county, city, and school district sets its own rate based on what it needs to spend. This means your actual bill depends on where your property sits, not just which state you live in. Two houses of identical value in the same state can have very different tax bills if they're in different counties.
Key Takeaways
- Hawaii, Alabama, and Louisiana do not charge property tax on residential real estate, though they tax other types of property or use other revenue sources instead.
- In states that do charge property tax, rates vary by county and city because local governments set their own rates based on their budgets.
- Property tax rates range from under 0.3% of home value in Hawaii and Louisiana to over 2% in states like New Jersey, Illinois, and Connecticut.
- Some states exempt certain types of property — agricultural land, religious buildings, or homes owned by seniors — from property tax or allow partial reductions.
States with no residential property tax
Hawaii does not tax residential real estate. It funds schools and local government through general excise tax (a sales-like tax on most transactions), income tax, and property taxes on commercial and industrial property only. Homeowners in Hawaii pay no annual property tax on their house, though they do pay property tax on rental properties and business property.
Alabama exempts homestead property — a primary residence — from property tax if the owner meets income limits. Most homeowners pay no property tax, though the state does tax investment property and commercial real estate. The income threshold varies by county.
Louisiana exempts homestead property from property tax as long as it is your primary residence and you meet residency requirements. Like Alabama, Louisiana taxes commercial and rental property. The homestead exemption is automatic for Louisiana residents; you do not need to file separately to claim it.
How property tax rates differ by state
States that do charge property tax set a statewide framework, but the actual rate you pay is determined by your county, city, and school district. This is why two identical houses in the same state can have different bills. A house in a wealthy suburb with well-funded schools may have a higher rate than one in a rural area with fewer services.
Effective property tax rates — the percentage of home value you pay annually — range widely. States with the lowest rates include Louisiana (under 0.3%), Hawaii (0.3%), and Alabama (0.4%). States with the highest rates include New Jersey (2.1%), Illinois (2.1%), Connecticut (2.1%), and Wisconsin (1.8%). In practical terms, a $300,000 home in New Jersey might cost $6,300 per year in property tax, while the same house in Louisiana might cost $900.
The rate you see on a tax bill is usually expressed as a mill rate — the amount per $1,000 of assessed value. A mill rate of 15 mills means you pay $15 per $1,000 of assessed value, or 1.5% of the home's value. Your county assessor's office publishes the mill rate for your area, and you can find it on your property tax bill or the assessor's website.
What property tax actually funds
Property tax revenue goes to local schools, police and fire departments, road maintenance, libraries, and county government operations. Because each locality sets its own rate based on its budget, areas with more expensive services or lower property values tend to have higher rates. A school district that spends more per student, or a county with aging infrastructure, will charge a higher rate to raise the same amount of money.
This is also why property tax varies so much within a single state. A rural county with one small school district and minimal services might have a mill rate of 8, while a suburban county with multiple school districts and more services might have a mill rate of 20. Both are in the same state, but the tax bill is very different.
Exemptions and reductions available in most states
Most states offer property tax breaks for certain groups or types of property. Homestead exemptions reduce the assessed value of a primary residence, lowering the tax bill. Agricultural exemptions tax farmland at a much lower rate than residential land to keep farming affordable. Religious and nonprofit exemptions remove churches, charities, and schools from the tax roll entirely.
States also commonly offer reductions for seniors, disabled homeowners, and veterans. These might be a flat dollar amount off the bill, a percentage reduction, or a freeze on the assessed value so it does not increase with the market. The rules and amounts vary by state and sometimes by county. Your county assessor's office can tell you which exemptions you might be may have access to to and how to claim them.
Some states have circuit-breaker programs that reduce property tax for low-income homeowners. These programs cap the amount of property tax you pay as a percentage of your income. If your property tax bill exceeds a certain percentage of your household income, the state reimburses you for the overage. Income limits and the percentage threshold vary by state.
How assessed value affects your bill
Your property tax bill is calculated by multiplying your property's assessed value by the mill rate. The assessed value is not necessarily what you paid for the house or what it would sell for today — it is an estimate made by your county assessor. Assessors use sales data, comparable properties, and property characteristics to estimate value. In some states, the assessed value is a percentage of market value (often 50% or less); in others, it is meant to be 100% of market value.
Assessed values are usually updated every few years, though some states reassess annually. When your home is reassessed and the value goes up, your property tax bill goes up even if the mill rate stays the same. This is why homeowners sometimes see their tax bill increase year to year. If you believe your assessed value is too high, you can file an appeal with your county assessor's office, usually within a set window after you receive the assessment notice.
Frequently Asked Questions
Do I pay property tax in Hawaii, Alabama, or Louisiana?
If your primary residence is in Hawaii, Alabama, or Louisiana, you likely do not pay property tax on it. Hawaii exempts all residential property; Alabama and Louisiana exempt homestead property (your primary residence). You would still pay property tax on rental properties, investment property, or commercial real estate in these states.
Can I reduce my property tax bill?
Most states offer exemptions or reductions for homeowners, seniors, disabled people, veterans, and agricultural property. Your county assessor's office maintains a list of programs you may be may have access to to. You typically must file a form to claim an exemption; it is not automatic except in a few states like Louisiana.
Why did my property tax bill go up if the mill rate didn't change?
Your bill increased because your assessed value went up. Assessors reassess property periodically, and when the estimated value of your home increases, your tax bill increases even if the mill rate stays the same. You can appeal an assessment you believe is too high by contacting your county assessor's office.
What is the difference between assessed value and market value?
Market value is what your home would sell for today. Assessed value is an estimate used for tax purposes, and it may be lower or equal to market value depending on your state's rules. Some states assess at 50% of market value; others assess at 100%. Your county assessor determines assessed value using sales data and property comparisons.
How do I find out what my property tax rate is?
Your property tax bill shows the mill rate or effective tax rate for your property. You can also contact your county assessor's office or visit their website — most publish mill rates by district. Your county tax collector's office can also provide this information if you give them your property address.
