Property Tax Rates by State: 2026 Complete Guide

Property tax is the single largest annual cost of homeownership in most of the United States — and the one with the widest variation. The same $300,000 home generates a $960 annual bill in Hawaii and a $6,690 bill in New Jersey. Where you buy matters more than how much you buy, and most homeowners discover that fact only after closing.

This guide ranks all 50 states + DC by effective property tax rate using Tax Foundation 2024 data and Census ACS 5-year medians, with side-by-side median home values and resulting annual bills. It also covers the five highest and five lowest states in detail, the most common exemptions by state, and the 7-step process for appealing an over-assessment.

How property tax actually works

Property tax is levied by local government — usually a combination of county, city, and school district — not by the state itself. Each taxing authority sets its own rate (often expressed in "mills," where 1 mill = $1 per $1,000 of assessed value), and your total bill is the sum of all of them. Three states (Connecticut, Maine, Massachusetts) have town-based assessment; the rest use county-level systems.

The formula has three moving parts. Assessed value is what the local assessor says your home is worth — sometimes equal to market value, sometimes a fraction of it. Assessment ratio is the percentage of assessed value that's actually taxed (100% in most states, but as low as 4% in South Carolina for owner-occupied homes). Tax rate is the mill rate or percentage applied to taxable value.

Combined: Annual tax = Assessed value × Assessment ratio × Tax rate. To compare across states with different ratios, analysts use the effective rate: actual taxes paid divided by market value. That's the only number worth comparing.

Effective vs nominal rates

Nominal rates are inflated by fractional assessment ratios that vary state-by-state and even county-by-county. Effective rates collapse the math to one number — what percentage of your home's true market value you pay in tax each year.

National average effective rate (2024 Tax Foundation): 0.99%, or about $2,970 on a $300,000 home. The 50-state range is 0.32% (Hawaii) to 2.23% (New Jersey) — a 7× spread on identical home values.

"Same $300,000 home, same square footage — $960/year in Hawaii, $6,690/year in New Jersey. The mortgage rate gets all the attention; the property tax line does the actual damage."

All 50 states + DC ranked (2026)

Sorted by effective property tax rate, highest to lowest. Median home value is from Census ACS 5-year data; median annual tax is computed from rate × median value (what a typical homeowner in that state actually pays). National average effective rate ≈ 0.99%.

Within any state, urban counties and well-funded school districts can run 30-60% above the state average; rural counties run well below. For a county-level estimate, use our Property Tax Calculator.

States with the highest property tax

The top 5 — New Jersey, Illinois, New Hampshire, Vermont, Connecticut — all share two structural features: heavy reliance on property tax to fund K-12 education, and limited use of other revenue sources (sales tax, income tax) to offset the burden.

New Jersey (2.23% effective)

NJ has been #1 for over two decades. The driver is school funding — roughly 60% of NJ property tax goes to local public schools, and per-pupil spending is among the highest in the nation ($23,000+/yr). Town-level home rule means hundreds of separate school districts, each with their own bond debt and pension obligations. The 2017 federal SALT cap ($10k limit on state and local tax deductions) hit NJ harder than any other state — owners in towns like Tenafly, Princeton, and Short Hills routinely pay $15,000-30,000/year in property tax on homes with rates above 3%.

Illinois (2.08% effective)

Illinois is structurally similar to NJ but with worse public-pension funding. Cook County (Chicago) and the collar counties carry decades of underfunded pension obligations baked into the property tax base. Effective rates in Cook County suburbs frequently exceed 2.5%; downstate counties (Champaign, Peoria) run closer to 1.8%. Illinois caps tax growth for non-home-rule districts at 5% or CPI, whichever is lower — but home-rule cities (Chicago, Naperville) are exempt and have raised rates faster.

New Hampshire (1.93% effective)

NH is the only top-5 state with no income tax and no general sales tax — property tax does essentially all the work. Rates have climbed in line with home appreciation. Sea-coast towns (Rye, Hampton) and Lakes Region towns (Wolfeboro, Meredith) hit 2.5-3% effective in some years. The state offers a homestead exemption only for low-income elderly homeowners.

Vermont (1.83% effective)

Vermont uses a state-level education property tax (Act 60/68) that effectively redistributes funding from wealthier towns to poorer ones. Combined with town municipal taxes, effective rates land in the high 1s. The state offers an "income sensitivity" adjustment that caps property tax at a percentage of household income for owners earning under ~$140k — many lower-income owners pay materially less than the nominal rate.

Connecticut (1.79% effective)

CT property tax is purely town-level (no county property tax). Wealthy Fairfield County towns (Greenwich, Westport, Darien) have lower effective rates (1.0-1.3%) because they have high home values; lower-income cities (Hartford, Bridgeport, Waterbury) have effective rates of 2.5-3.5% because their grand lists can't support municipal services on their own. The state has discussed a regional-equalization mechanism for years but has not enacted one.

States with the lowest property tax

The bottom 5 — Hawaii, Alabama, Colorado, Louisiana, South Carolina — each get there through a different mechanism. Cheap effective rates don't always mean cheap total cost of ownership.

Hawaii (0.32% effective)

The lowest property tax rate in the nation, but applied to the nation's highest median home values ($729,100). The math: 0.32% × $729k = $2,330 — roughly the U.S. average bill on a state-average home worth 2.4× the U.S. median. Hawaii funds state operations through high income tax (top bracket 11%) and a general excise tax (4% on essentially every transaction, including services). The low property tax keeps long-time residents from being priced out by appreciation.

Alabama (0.42% effective)

Alabama's low rate is partly a constitutional cap (Lid Bill) limiting annual reassessment growth. The state ranks near the bottom in per-pupil school funding and has historically relied on sales tax (state + local sales tax in Birmingham exceeds 10%) instead of property tax. Counties have very limited authority to raise rates without statewide vote.

Colorado (0.55% effective)

Colorado's Taxpayer's Bill of Rights (TABOR) constrains revenue growth and requires voter approval for new taxes. The Gallagher Amendment historically pushed residential assessment ratios down; though Gallagher was repealed in 2020, the legacy of low residential burden persists. Front Range home appreciation has pushed total bills up despite the low rate.

Louisiana (0.55% effective)

The constitutional homestead exemption shields the first $75,000 of every owner-occupied home's value from parish (county) tax. On a $200,000 home, you pay tax on $125,000 — a 38% reduction off the top. Louisiana also leans heavily on a 4.45% state sales tax + local sales taxes that often push combined rates above 10%.

South Carolina (0.56% effective)

The 4% owner-occupied assessment ratio is the key. Non-owner-occupied properties (rentals, second homes) are assessed at 6%, and commercial at 6% — those owners pay roughly 50% more than the "effective rate" suggests. The low primary-residence rate is offset by some of the highest auto property tax rates in the U.S. (calculated annually on vehicle value).

How property tax is calculated

Walk through the math step-by-step:

1. The assessor estimates your home's market value. Methods: comparable sales (most common), cost approach (replacement cost minus depreciation), or income approach (for rental properties). Assessors do "mass appraisal" — algorithm + sample inspections, not per-property appraisal — so errors are common.
2. Apply the assessment ratio. Most states use 100% (market value = assessed value). Outliers: SC (4% owner-occupied), Arkansas (20%), Mississippi (10% owner-occupied), some Florida counties (with caps via Save Our Homes amendment).
3. Subtract exemptions. Homestead, senior, veteran, disabled, agricultural — each reduces the taxable value before the mill rate is applied.
4. Apply the mill rate. 1 mill = $1 per $1,000 of taxable value. So 25 mills = 2.5% of taxable value. Mill rates are set annually by the local taxing authorities based on their budget needs.
5. Equalization (some states). In states with multi-county taxing districts, an "equalization factor" adjusts for differences in assessment practices between counties so the state-funded portion (often schools) is distributed fairly.

The result is your annual tax bill. Most jurisdictions split it into two semiannual or quarterly payments; some allow monthly escrow through your mortgage servicer.

Exemptions by state

Almost every state offers some combination of homestead, senior, veteran, disability, and agricultural exemptions. Most homeowners qualify for at least one and never apply.

Other commonly available exemptions: agricultural / forestry-use (large rural parcels can drop 50-90% if actively farmed); historic preservation (10-50% reduction for designated landmarks); renewable energy (about 30 states exempt the value added by solar panels). Apply through your county assessor. Most renew automatically; senior and ag-use often require annual re-certification — missing the deadline costs a full year of benefit.

How to appeal your assessment (7 steps)

The National Taxpayers Union estimates 30-60% of homes are over-assessed at any given time. Success rates on appeals run about 40% nationally, with median savings of $500-$2,000 per year. Here's the process:

1. Gather comparable sales. Pull 3-5 recent sales (last 12 months) of homes within ~0.5 miles, same age (±10 years), similar square footage (±15%), similar bed/bath count, similar lot size. Zillow, Redfin, and your county recorder's office all have free comp data. Aim for sales that closed before or around the assessment date.
2. Request your assessment record from the county assessor. This is public information, free. Verify the listed square footage, bedroom and bath count, lot size, year built, garage type, finished basement, pool, and condition rating. Data errors are the single most common winning argument — a typo that says your 1,800 sqft home is 2,100 sqft inflates your assessment.
3. Calculate your "true" value. Average the comp sales and adjust for differences (more bedrooms, smaller lot, pool, basement finish). If your true value is more than ~10% below the assessor's number, you have a case worth pursuing.
4. File the appeal within the deadline. Most counties give 30-60 days from the date the assessment notice was mailed. Some require a written form; some allow online filing. Missing the deadline forfeits the year — there's almost never an exception.
5. Prepare your evidence packet. Include the comp data (with photos and sale prices), the corrected assessment record (showing any data errors), and a one-page summary of your argument. Most appeals are won by being organized, not by being aggressive.
6. Attend the informal hearing. Most counties hold a 15-30 minute hearing where you present your case to an assessor representative. Be polite, factual, and brief. The assessor often makes a partial reduction at the hearing — accept it or push to the next level.
7. Escalate if needed. If the informal hearing doesn't produce an acceptable result, you can appeal to the county Board of Equalization or Review (formal hearing, usually within 60-90 days), and then to state tax court (rarely worth it unless the disputed amount is >$10,000/year). Most appeals end at step 6.

Why rates vary so much

Three structural factors explain almost all of the variation between states:

• What property tax funds locally. In high-rate states (NJ, IL, NH, CT), property tax is the dominant source of K-12 school funding. In low-rate states (HI, AL, LA), schools are funded more from sales tax, income tax, or state aid.
• Whether the state has alternative revenue. Texas, Tennessee, Florida, and New Hampshire have no state income tax and lean harder on property tax. States with high income tax (CA, NY, OR) can run lower property taxes.
• Caps, freezes, and homestead protections. California's Prop 13 (1978) caps annual assessment increases at 2%, which is why long-time California owners often pay 30-50% less than the table suggests despite high home values. Texas now has a similar 10%/year cap on owner-occupied homes (Prop 1, 2007). Florida's Save Our Homes amendment is a 3% annual cap.

The result is a structural mismatch between what news headlines say ("Hawaii has the lowest property tax!") and what total state tax burden actually looks like. Always look at total state and local tax burden — Tax Foundation publishes this annually — before relocating for tax purposes.
