Estimate what moving would do to your property tax bill — using your current home’s value and the price of the home you’d actually buy, with each state’s exemptions applied. Estimates only, for the first year of ownership.
Your figures stay in your browser. This tool runs entirely on your device. Nothing you enter is sent to us, stored, or saved.
Both sides run through the same calculation engine this site uses to model each state’s property tax rules — assessment ratios, homestead exemptions, senior exemptions and freezes, and statutory caps that apply in the first year of ownership. The rates come from the primary taxing district of each county’s seat.
It covers the first year only. That is a deliberate limit, not an oversight. Several states cap how fast your assessment can rise after you buy — Florida’s Save Our Homes at 3% a year, California’s Proposition 13 at 2%, Texas at 10% for homesteads — and those caps are exactly what make a ten-year picture diverge from a one-year one. The engine behind this site is a single-year estimate and does not model that behaviour, so any multi-year figure would be invented rather than calculated. We would rather give you one number we can stand behind.
What that means in practice: if you are moving from a long-held home in a capped state, your current bill may be far below what this tool estimates, because you have years of cap protection this calculation cannot see. The destination figure — a fresh purchase at market value — is the more reliable half of the comparison.
The Compare tool shows what a single reference home would cost in two counties, which is useful for browsing. This one is personalised: you enter what your current home is worth and what you would actually pay for the home you are moving to, because those are usually different numbers and the difference often matters more than the rate gap does.
Because that is the only figure this site can stand behind. Several states cap how fast an assessment can rise once you own a home — Florida’s Save Our Homes at 3%, California’s Proposition 13 at 2%, Texas at 10% — and those caps are what make the long-run picture diverge from year one. Our calculation engine is a single-year estimate and does not model that year-over-year behaviour, so a five or ten year projection would be invented rather than calculated. We would rather show you one number we trust than three we do not.
Yes, where the engine models them. Ticking primary residence applies each state’s homestead treatment, and the senior option applies over-65 exemptions and freezes where they exist. Income-tested programmes are generally not applied, because we do not ask for your income — so if you qualify for one, your real bill could be lower than shown.
No. Everything runs in your browser. Nothing you enter is transmitted, stored, or saved. There is no backend and no database. If you share the link, only the counties and values in the address bar travel with it — and only because you chose to share it.
The biggest reason is that we use the county seat’s primary taxing district. Within one county, rates commonly vary by a factor of two or more between cities, school districts, and special districts such as municipal utility districts. Your specific parcel’s assessed value, any local assessments, and exemptions we cannot see will all move the number.
Estimates only. The Property Tax Almanac is an independent editorial reference. It is not affiliated with, endorsed by, or acting on behalf of any government agency, assessor’s office, appraisal district, relocation service, or tax service. Nothing this tool produces is a quote, a bill, an appraisal, or a determination of what you will owe anywhere.
Based on county-level averages. Both sides are calculated from the primary taxing district of the county seat. Within a single county, effective rates commonly vary by a factor of two or more between cities, school districts, municipal utility districts, emergency services districts, and other special assessments. Your actual bill depends on your specific parcel, its assessed value, the exact districts your address falls in, and exemptions this tool cannot see — including income-tested programmes, since we do not ask for your income.
First year of ownership only. This tool does not project future years. It does not model assessment caps compounding over time, reassessment cycles, changes in your home’s value, rate changes adopted by local budgets or voters, or changes in law. A figure that looks favourable in year one can look different after several years in a state with strong caps — and vice versa.
Rates and rules change. County rate data is compiled from public sources and believed accurate as of the date shown on each county page. Rates change annually, sometimes mid-year, through local budget adoptions, legislative action, and voter-approved measures.
No legal, tax, financial, or real estate advice; no warranty. Nothing here constitutes legal, tax, financial, investment, or real estate advice. We make no representations or warranties of any kind, express or implied, about the completeness, accuracy, reliability, or suitability of any result. Any reliance you place on it is strictly at your own risk, and we are not liable for any loss or damage — including indirect or consequential loss — arising from its use or from decisions made on the basis of it.
Confirm before you decide. A move is a large financial decision and this tool is not a basis for making one. Contact the assessor or appraisal district in both counties — every county page on this site lists their phone number and website — and consider speaking to a qualified tax professional, appraiser, or attorney familiar with both states.
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, the Wisconsin Department of Revenue, the Michigan Department of Treasury, the Iowa Department of Revenue and Iowa Department of Management, the Minnesota Department of Revenue, the California State Board of Equalization, 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), Mello-Roos Community Facilities Districts (CFDs), 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, Wisconsin's Lottery & Gaming Credit, Michigan's Proposal A 5%/IRM cap, Iowa's residential rollback, Minnesota's Homestead Market Value Exclusion, California's Proposition 13 acquisition-value system and 2% annual cap), and any appeal or protest outcomes. For an authoritative figure, consult your county appraisal district (Texas), county assessor (Indiana, Illinois, Tennessee, Arizona, North Carolina, Iowa, Minnesota, California), county property appraiser (Florida), or municipal/township assessor (Wisconsin and Michigan — assessments are set at the city/village/township level rather than the county level; some Iowa and Minnesota cities also have city-level assessors). The contact information for the primary authority in each county is listed at the top of that county's page.
