New Jersey has the highest effective property tax rate in the country
New Jersey residents pay the highest property taxes as a percentage of home value. The state's effective property tax rate is around 0.85% of assessed home value annually, meaning a homeowner with a $400,000 house pays roughly $3,400 per year in property tax alone. This is roughly double the national average of 0.42%.
Illinois, Connecticut, and Vermont also rank in the top five states for property tax burden. However, "highest" can mean different things: some states charge high rates on lower-assessed values, while others charge lower rates on higher-assessed values. The actual dollar amount you pay depends on both the tax rate and how your local assessor values your home.
Property tax rates also vary significantly within each state. A town in New Jersey's Bergen County may have a different rate than one in Atlantic County. Your specific bill depends on your municipality, not just your state.
Key Takeaways
- New Jersey's effective property tax rate of approximately 0.85% is the highest in the nation, roughly double the national average.
- Your actual property tax bill depends on both your state's tax rate and your local municipality's assessment practices, so two homes of equal value in the same state can have different bills.
- Illinois, Connecticut, Vermont, and New Hampshire round out the top five states for property tax burden.
- Some states with high rates tax lower-assessed home values, while others tax higher-assessed values at lower rates, making direct state-to-state comparison complex.
How property tax rates are calculated and why they vary by state
Property tax is calculated by multiplying your home's assessed value by the local tax rate, usually expressed as a percentage or per $1,000 of assessed value. A state's effective tax rate is the average of all these local rates combined. States set the legal framework for how assessments happen, but towns and counties do the actual work.
States differ in how often they reassess homes, what they use as the basis for assessment (recent sales, income approach, cost approach), and whether they cap how much assessments can rise year to year. New Jersey reassesses frequently and bases assessments on market value, which keeps rates high. Other states reassess less often or use older valuation methods, which can keep effective rates lower even if the nominal tax rate looks similar.
Some states offer property tax exemptions or credits for seniors, veterans, or homeowners with disabilities. These reduce the actual tax owed but do not change the stated rate. A state might have a high rate but lower effective burden if exemptions are widespread.
States with the highest property tax rates
| State | Effective Tax Rate (approximate) | Typical annual tax on $300,000 home |
|---|---|---|
| New Jersey | 0.85% | $2,550 |
| Illinois | 0.78% | $2,340 |
| Connecticut | 0.75% | $2,250 |
| Vermont | 0.73% | $2,190 |
| New Hampshire | 0.72% | $2,160 |
These figures are approximate and based on recent data, but rates change annually as local budgets shift. A town that funds schools through property tax alone will have a higher rate than one that receives state education funding. This is why neighboring towns in the same state can have very different bills.
States with the lowest effective rates include Hawaii (0.28%), Alabama (0.41%), and Louisiana (0.55%). Even within low-tax states, however, some municipalities charge significantly more than the state average.
Why some states have higher property taxes than others
States with high property taxes often rely on property tax revenue to fund schools, roads, and local services rather than relying on state income tax or sales tax. New Jersey has no state sales tax on groceries and clothing, and its income tax is progressive, so the state shifted more of the funding burden to property owners. Connecticut and Illinois have similar structures.
States with lower property taxes often have higher income taxes or sales taxes, or they receive more funding from state government for local services. The total tax burden—income, sales, and property combined—can be similar across states, but it is distributed differently.
Population density also matters. Densely populated states like New Jersey and Connecticut have higher land values, which increases assessed values and therefore tax revenue even at lower rates. Rural states with lower land values may have higher nominal rates but lower actual bills because homes are worth less.
How to find your state's property tax rate and your local rate
Your state's tax assessor or department of revenue publishes effective tax rates by county and municipality. Search "[your state] property tax rates by county" or visit your state's official tax website. Most states post this information publicly.
To find your specific local rate, contact your town or county assessor's office. They can tell you your home's assessed value and your exact tax rate. You can also find this information on your property tax bill, which lists the assessed value and the rate applied to it.
Some online tools estimate property taxes by state and county, but they use averages and may not reflect your specific municipality. Your assessor's office has the actual number.
What you can do if your property taxes are high
If you believe your home's assessed value is too high, you can file an assessment appeal or challenge with your local assessor. The process and deadline vary by state and municipality. Most states require you to file within 30 to 45 days of receiving your assessment notice.
You may also be may have access to to exemptions or credits. Homeowners over 65, veterans, people with disabilities, and agricultural property owners often may have access to for reductions. Contact your assessor's office to ask what programs exist in your municipality.
Some states allow homeowners to defer property taxes or offer property tax relief programs for low-income households. These vary widely by state. Your local assessor or your state's revenue department can tell you what is available where you live.
Frequently Asked Questions
Does a high property tax rate mean I will pay more than someone in a low-tax state?
Not necessarily. A state with a 0.85% rate on a $300,000 home pays $2,550 per year. A state with a 0.40% rate on a $500,000 home pays $2,000 per year. Home values, assessment practices, and what services are funded by property tax versus income tax all affect your actual bill. Compare your total state and local tax burden, not just property tax.
Can I move to a lower-tax state to reduce my property taxes?
Yes, but weigh the full cost. Moving expenses, income tax differences, and cost of living in your new state matter. Some lower-tax states have higher income taxes or higher costs for housing, utilities, or services. Calculate your total tax burden in both states before deciding.
What happens if I do not pay my property taxes?
Your municipality can place a lien on your home, charge penalties and interest, and eventually foreclose and sell your property to recover the debt. The timeline varies by state, but it typically begins within one to three years of nonpayment. Contact your assessor's office immediately if you cannot pay.
Are property taxes the same every year?
No. Your tax bill changes if your home's assessed value changes, if the local tax rate changes, or if you gain or lose an exemption. Most municipalities reassess every one to five years, though some reassess annually. Your bill can rise or fall depending on local budget needs and property market conditions.
Can I deduct property taxes on my federal income tax return?
Yes, but with limits. The federal government allows you to deduct up to $10,000 in combined state and local taxes (including property tax, income tax, and sales tax) on your federal return. This limit applies regardless of how much you actually paid. Consult a tax professional about whether this deduction benefits you.
