Thinking of moving from Illinois to Florida? Chicago to Nashville? California to Phoenix? This tool calculates the actual property tax bill on a hypothetical home in any two counties we cover — applying each state's real homestead exemptions, assessment caps, and equalization factors — so you can see the annual difference at a glance.
Median effective property tax rate across the counties we cover in each state, with the estimated annual bill on a typical $400,000 home. Ranked lowest to highest.
Effective rate = annual tax bill divided by home market value. These are medians across the counties we cover — which skew toward urban/suburban counties with the largest populations. Rural counties often have substantially lower rates.
Pick one county from each side. The calculator applies each state's actual tax law to the home value you enter and shows the difference side by side.
These are the searches we see most often — pre-configured so you can jump straight to the numbers.
Illinois lost a net 82,900 residents to other states in 2024, according to the US Census Bureau's American Community Survey. The state has ranked among the worst three in the country for net domestic migration every year since 2014, alongside California and New York. Illinois lost the most residents to Florida (11,659), Indiana (11,629), Wisconsin (9,914), Missouri (7,470), and Tennessee (6,874) — all lower-tax states. In total, approximately 95% of Illinois out-migrants moved to states with lower combined tax burdens.
Florida is the #1 destination for Illinois out-migrants and the top net-migration state in the country overall. Homeowners benefit from no state income tax, a $50,000+ homestead exemption (now CPI-indexed under Amendment 5), and the Save Our Homes 3% cap on assessed value growth. Texas is #2 nationally — no state income tax, a $100,000 school-district homestead exemption, and newer housing stock in its growing metros. Tennessee attracts movers with no state income tax and low effective property tax rates, though with no state homestead exemption (its 25% residential assessment ratio is the entire story). Arizona's Maricopa County was the #1 US county for net migration in 2023, helped by the 1% constitutional cap on primary property tax and Proposition 117's 5% annual cap on Limited Property Value growth. North Carolina ranked #2 nationally in net domestic migration in 2024, behind only Texas, with Charlotte and Raleigh among the fastest-growing metros in the US — though unlike Florida and Texas, NC has no universal homestead exemption and a 4.25% state income tax.
For Illinois residents moving across state lines, Indiana is the most common destination for the Chicago metro area specifically. The Lake County, Indiana communities of Hammond, Munster, Schererville, and Crown Point have absorbed large numbers of former Cook County residents who kept jobs in Chicago but gained the benefit of Indiana's 1% constitutional cap on homestead property tax. Indiana's combination of low home values, the 1% circuit-breaker cap, and commutable access to Chicago makes it uniquely attractive for short-distance moves.
Polls from NPR Illinois and the Paul Simon Public Policy Institute have consistently found that property taxes are the single largest factor Illinoisans cite when considering leaving the state. But a move isn't just about the property tax rate. Texas and Florida have similar nominal rates to Illinois, but homes are valued differently (Florida's SOH cap helps long-term owners; Texas's homestead $100K is front-loaded). Tennessee has low overall rates but no homestead protection, so year-one bills can be surprisingly high. Arizona's 10% assessment ratio on primary residences means its nominal rates look much higher than its effective rates. The comparison tool above lets you enter your actual home value and see exactly what the difference would be for any specific pair of counties you're considering.

This calculator applies each state's actual property tax calculation to the home value you enter:
Rates shown reflect the primary taxing district of each county's seat. Your actual bill will vary by neighborhood, school district, and local special taxing units (MUDs in Texas, community development districts in Florida, fire districts in Arizona, etc.). This tool is for directional comparison — always confirm the specific district rates for any home you're seriously considering.
About this site's data and estimates. The Property Tax Almanac is an independent editorial reference. It is not affiliated with any government agency, tax assessor, or tax preparation service. The calculators and data on this site are informational and are not a substitute for advice from a qualified tax professional, attorney, or your official county assessor or appraisal district.
Accuracy, sources, and scope. Tax rate data is compiled from publicly available sources — including the Texas Comptroller of Public Accounts, the Indiana Department of Local Government Finance, the Illinois Department of Revenue, the Florida Department of Revenue, the Tennessee Comptroller of the Treasury, the Arizona Department of Revenue, the North Carolina Department of Revenue, individual county appraisal and assessor offices, and the US Census Bureau — and is believed to be accurate as of the "revised" date shown on each page. Rates change annually (and sometimes mid-year) through local budget adoptions, legislative action, and voter-approved measures. Rates displayed reflect the primary tax district of the county seat; rates in other cities, school districts, Municipal Utility Districts (MUDs), Emergency Services Districts (ESDs), and special taxing units within the same county may be meaningfully higher or lower. Census population figures are from the 2020 Decennial Census and are rounded to the nearest 100.
How to use these estimates. The calculator produces a rough estimate based on the county seat's combined rate, statutory deductions and exemptions available statewide, and the value you enter. Your actual bill depends on your specific parcel's assessed or appraised value, the exact taxing entities covering your address, any local-option exemptions you qualify for, any assessment caps or circuit-breaker protections (e.g., Florida's Save Our Homes, Arizona's Prop 117 LPV cap, Indiana's 1% circuit breaker, North Carolina's Elderly/Disabled Exclusion), and any appeal or protest outcomes. For an authoritative figure, consult your county appraisal district (Texas), county assessor (Indiana, Illinois, Tennessee, Arizona, North Carolina), or county property appraiser (Florida). The contact information for the primary authority in each county is listed at the top of that county's page.
