Property Tax Information for Every State, in One Place
An independent national directory of US property tax — covering all 50 states, the District of Columbia, and the 3,000+ counties that actually run assessment, appeal and collection. Statutes, deadlines, exemptions, and links to every official portal you need.
What This Site Is For
Property tax in the United States is one of the most fragmented systems any homeowner has to deal with. There is no single federal property tax. Instead, each state has its own statutory framework, and within each state, counties (or in a handful of states, towns and townships) actually administer assessments, hear appeals, and bill the tax. The result is more than 13,000 separate assessing jurisdictions, each with its own portal, its own forms, and its own deadlines.
propertytaxusa.org/ consolidates this into one consistent format. For every state, the page tells you how property tax works in that state, who administers it, what exemptions exist, when the appeal window opens, and how to find your specific county's assessor and tax collector. For high-volume counties, dedicated pages go further — linking the property search portal, the homestead application, the appeal form, and the tax bill payment portal directly.
We are completely independent. We are not a state tax department, not a county assessor, not the IRS, and not affiliated with any property-tax-protest firm or consulting service. We are an editorial reference site, full stop.
How US Property Tax Actually Works
The framework looks complex from the outside but reduces to a few moving parts. Every property tax bill in the country is the product of these:
The state framework
State law sets the rules — what’s taxable, what exemptions are mandatory, what the appraisal cycle looks like, and what kind of cap (if any) applies to assessed value.
The county assessor
The local official who appraises every taxable parcel each year (or on the cycle the state requires). Goes by different names — assessor, appraiser, property valuation administrator, board of revision — depending on the state.
The homestead exemption
Almost every state offers some form of reduction for an owner-occupied primary residence. Amounts vary wildly — from a few thousand dollars to hundreds of thousands of dollars in some states.
The appeal board
If you disagree with your assessed value, every state has a route to challenge it — county boards of equalization, boards of review, ARBs, value adjustment boards. Names differ; the function is the same.
The tax collector
A separate office (treasurer, tax collector, sheriff in some states) bills and collects the tax once values are certified. Different from the assessor — paying late or short to one doesn’t help you with the other.
The taxing units
Schools, counties, cities, fire districts, water districts, hospital districts — each adopts its own millage or tax rate. Your bill is the sum of all of them, applied to your taxable value.
Property tax is local. Two counties in the same state often run different portals, different appeal-form numbering, and different fee schedules. We document each state and county separately so you don’t apply California’s rules to a Florida problem.
What You’ll Find on Each State Page
For every state we cover, the page answers the same set of questions in the same order:
- Who runs it — the state department of revenue, taxation, or board of equalization that oversees property tax
- Who actually assesses — counties in most states; towns/townships in New England states; statewide assessments for utility property in some states
- Assessment cycle — annual, biennial, every four years, or rolling — depending on state law
- Assessment ratios and caps — California’s Prop 13 base year, Florida’s Save Our Homes 3% cap, Michigan’s Headlee/Proposal A, New York’s STAR program, and similar state-specific rules
- Homestead and senior exemptions — including over-65, disabled person, disabled veteran, and surviving spouse rules
- Appeal deadlines — set by state statute, typically tied to the assessor’s value notice or to a fixed annual date
- Property tax circuit breakers where the state runs an income-based relief program
- SALT deduction context — how the federal $10,000 SALT cap (TCJA, currently sunsetting after 2025) interacts with property tax
- Where to find your specific county — direct links to county assessor and tax collector directories
How We Verify the Information
Every fact on a state or county page comes from one of three places, in this order:
- The state’s own department of revenue, taxation, or board of equalization website — for statewide rules, exemption forms, and statutory references
- The county’s own assessor and tax collector websites — for portals, forms, and deadlines that apply at the county level
- The state code itself, accessed through the official state legislature or revisor’s office — for statutory authority and exemption eligibility rules
Every state page is reviewed at least quarterly. Appeal deadlines, exemption forms, and assessment cycles are time-sensitive content — we treat them with explicit “last reviewed” dates and verify URLs live before publication. The full source hierarchy is on the Sources & Methodology page.
Who This Site Is For
- Homeowners who got a value notice and need to figure out what it means and what to do
- People who just bought a home and need to file for the homestead exemption — most states have a deadline
- Property owners considering an appeal who need to find the deadline, the form, and the right board
- Seniors looking up the over-65 exemption, the senior freeze, or the property tax circuit-breaker program in their state
- Disabled veterans looking up the disability-percentage exemption, which goes up to 100% on residence homestead in many states
- Investors and real-estate professionals doing diligence across multiple states
- Owners of agricultural, timber, conservation, or special-use land who need state-specific productivity-valuation rules
- Anyone facing a tax-sale, lien, or delinquency situation who needs to find the right state procedure quickly
The site is not a substitute for legal or tax advice. If you have a complex appeal, a tax-sale matter, or a federal tax issue tied to property, consult a licensed attorney or CPA in your state.
What We Don’t Do
- We don’t appraise property. The county assessor does.
- We don’t file appeals on your behalf. You file with the county or state appeal body, or hire a property-tax consultant.
- We don’t process homestead applications. You file directly with your county assessor.
- We don’t bill or collect property tax. The county tax collector does.
- We don’t represent any state, county, or the IRS.
- We don’t sell your data. See our Privacy Policy for the full position under CCPA/CPRA, the Texas TDPSA, and other state privacy laws.
How We Pay for the Site
propertytaxusa.org/ runs on display advertising shown alongside content. We don't accept paid placements that pretend to be editorial.

Corrections and Feedback
Property tax law changes frequently — new exemptions are enacted, deadlines are adjusted, county portals are redesigned, and some states overhaul whole systems on a few years’ cycle. If you spot something on the site that doesn’t match the current statute, the current state DOR guidance, or your county’s current page, please email us. We treat reader corrections as a priority queue and respond within seven business days.
Email info@propertytaxusa.org with the page URL and what you believe is incorrect. If you can include the link from the state DOR or the county that supports the correction, even better — that lets us cross-check and update without delay.
