Property tax tools

Practical tools for the two questions homeowners actually ask: am I being assessed fairly, and what would I pay somewhere else? Each one runs entirely in your browser — nothing you enter is sent to us or stored anywhere.

Monthly Payment Calculator New

Works out a full monthly payment — principal, interest, taxes, insurance, PMI and HOA — with the property tax line calculated from your county’s real rates instead of the flat national guess most mortgage calculators apply to every house in the country.

When to use this: Use it when you are working out what a specific house would actually cost per month, particularly if you are comparing homes across county or state lines where the tax difference is large.

Appeal Checker

Compares your assessment notice and tax bill against what is typical for your county, and tells you whether a closer look might be worthwhile. It works backwards from your state’s statutory assessment ratio to show what your assessor appears to think your home is worth, then measures that against your own estimate.

When to use this: Use it when your assessment notice arrives and the number looks higher than you expected — before you spend time on a formal appeal.

Relocation Calculator

Estimates what a move would do to your property tax bill using your own numbers — what your current home is worth and what you would actually pay for the next one — with each state’s exemptions and first-year caps applied to both sides.

When to use this: Use it when you have a specific move in mind and want the personalised figure. For browsing two areas against a single reference home, the County Comparison below is the better starting point.

County Comparison

Puts any two counties side by side and works out what the same home would cost you in each, applying real homestead exemptions, assessment caps, and equalization factors rather than a flat rate.

When to use this: Use it when you are exploring and want a like-for-like read on two areas. If you already know your own numbers, the Relocation Calculator above is the personalised version.

A note on what these can and cannot do

Every tool here works from county-level averages and published statutory rules. That makes them useful for orientation — for telling you whether something looks unusual and is worth investigating — and unsuitable as a substitute for your county’s own figures. None of them is an appraisal, a valuation, or tax advice, and none can tell you what your specific parcel is assessed at or why. For that, your county assessor or appraisal district is the only authority, and every county page on this site lists their phone number and website.

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.
