The Practical, Manually-Verified USA Directory of County Appraisal Districts, County Assessors & Property Appraisers β With Step-by-Step Protest Guides & Up-to-Date Deadlines
Step-by-step guides, manually verified phone numbers and addresses, manually captured agency-portal screenshots, and current 2026 information for every county-level property assessment office in the United States β Texas county appraisal districts (CADs), California county assessors, Florida county property appraisers, and the equivalent agencies in every other state. Property tax protest deadlines, exemption applications, ARB hearings, valuation methods, agricultural and homestead exemptions, business personal property, mineral rights, and tax sales β covered with the practical, actionable detail you need to act on time.
Property tax protest deadlines are statutory, narrow, and not extended for “I didn’t know.” The most common deadlines: Texas β generally May 15 (or 30 days after notice, whichever is later, under Tex. Tax Code Β§ 41.44); California β September 15 for the regular assessment-appeal filing window (varies July 2βNovember 30 depending on county); Florida β 25 days from the TRIM notice mailing date (Fla. Stat. Β§ 194.011); New York β Grievance Day, varies by municipality, typically 4th Tuesday in May. Always confirm with your specific county on its current notice β every county page on this site has the verified current-year deadline.
Information on this site about property tax assessment, exemptions, protest procedures, ARB hearings, valuation methods, agricultural valuations, mineral interests, business personal property, and similar topics is general informational material only. It is not legal advice, not tax advice, and we are not your attorney or your tax professional. For advice on a specific assessment or appeal, consult a licensed property-tax attorney, a Texas-licensed property tax consultant (Tex. Occ. Code Ch. 1152), or a CPA. Every county page lists local options where applicable.
What Sets county-cad.us/ Apart β The Manual-Verification Standard
Property tax assessment is the kind of domain where stale information costs real money. A wrong protest deadline costs an entire year. A wrong agency phone routes you to the wrong office during peak protest season. A broken portal link sends you in circles when you have a 14-day window to file a Notice of Protest. We built this site so that doesn’t happen.
Every county-level property assessment office in our directory is verified by a human editor against the agency’s own published page β not auto-scraped, not pulled from a stale third-party database, not generated. We go further than typical: we manually capture screenshots of the live agency portal at the time of verification, so the version of the interface and procedure we describe matches what you actually see when you click. When the agency redesigns its site, we re-verify and re-capture. When a county’s protest deadline is mailed, we update the page within days.
Every link clicked. A human editor opens every external URL and confirms the destination is the actual page β not a generic homepage redirect, not a 404, not a stale cached version. Every phone number dial-tested. We call main-line phone numbers on a quarterly cycle and during the heightened-review window before each county’s protest deadline. Every address cross-checked. Physical and mailing addresses verified against the county’s contact page and against USPS ZIP+4 lookup. Every portal screenshotted. We capture the agency’s portal interface at the time of verification β search box, login flow, exemption form list, online protest filing tool β so the walkthrough matches what you see. Every deadline tracked. Protest, exemption, late-filing, and ARB hearing deadlines tracked county-by-county, year-by-year.
What This Site Is For
Property tax assessment in the United States is overwhelmingly a county-level function. There is no federal property tax. State frameworks set the rules β the assessment standard, the exemption categories, the protest and appeal procedure β but the actual valuation of your home, your business, or your land is done by a county-level office. That office is called different things in different states: a “County Appraisal District” (CAD) in Texas, a “County Assessor” in California and most western states, a “County Property Appraiser” in Florida, a “County Assessor” or “Tax Assessor” in most other states. The function is the same: produce the assessed value that, multiplied by the millage or tax rate, becomes your property tax bill.
county-cad.us/ is the practical reference for that county-level layer. Every county page lists the verified office name, the agency's official URL, the property search portal, the exemption application portal, the protest filing tool, the ARB or assessment appeals board contact, the address, and the phone number β all manually verified against the agency's own page, all screenshot-verified at the time of capture.
We are completely independent. We are not affiliated with any state Department of Revenue, the Texas Comptroller of Public Accounts, the California State Board of Equalization, the Florida Department of Revenue, the International Association of Assessing Officers (IAAO), the National Association of Counties (NACo), the IRS, or any county appraisal district, county assessor, or county property appraiser.
The Eight Categories of Information You’ll Find on Each County Page
Property search
Direct deep-link to the county’s property search portal β search by owner name, address, parcel/account number, or geographic area. Screenshot-verified interface.
Exemption applications
Homestead, over-65/senior, disability, surviving spouse, veteran, agricultural, open-space, charitable, and other exemption categories β eligibility, application form, deadline.
Protest & appeal
Step-by-step protest filing β Notice of Protest deadline, evidence preparation, informal review, ARB or assessment appeals board hearing, evidence rules.
Tax bill payment
Payment portal, due dates, installment options, delinquency dates, tax-collector vs. assessor jurisdiction (varies by state).
Agricultural & open-space valuation
Special-use valuation programs (1-d, 1-d-1 in TX; California Williamson Act; Florida Greenbelt). Application requirements, rollback rules, qualification thresholds.
Mineral & oil/gas valuations
Mineral interest valuation (significant in TX, OK, ND, WY, NM); royalty interest assessment; non-producing minerals.
Business personal property (BPP)
Business personal property rendition, BPP exemption thresholds, depreciation schedules, late-filing penalties.
Tax sales & tax-defaulted property
Tax sale procedures (auction vs. sealed-bid; varies by state), redemption periods, struck-off property lists, tax certificate vs. tax deed states.
In Texas, the County Appraisal District (CAD) determines value; the county tax assessor-collector or other taxing units (school district, city, county) collect taxes. In California, the County Assessor determines value; the County Tax Collector collects. In Florida, the County Property Appraiser determines value; the Tax Collector collects. In most northeastern states, the assessment is done at the city/town level, not county. Knowing which office to call for what is half the battle.

How We Find and Verify β The Eight-Step Process (Updated)
- Identify the right authoritative source. We start with the county-level office’s page on the county’s .gov domain, cross-checked against the state coordinator (Texas Comptroller, California BOE, Florida DOR) and against IAAO and NACo directories.
- Verify the URL is live. A human editor clicks every link before publication and confirms the destination is the actual page β not a redirect to a generic county homepage, not a 404, not a stale cached version.
- Capture screenshots manually. The verifying editor manually takes a screenshot of the agency portal interface β homepage, property search, exemption application page, online protest filing tool β and stores it for reference. When the agency redesigns, we re-capture.
- Dial-test phone numbers. Main line, exemption line, protest hotline, ARB scheduling β each tested.
- Verify the agency address. Physical and mailing addresses cross-checked against the county’s contact page and against USPS ZIP+4 lookup. Some counties operate field offices (Harris CAD has multiple); each captured separately.
- Document procedures from the agency’s own published rules. Notice of Protest deadline, exemption application workflow, ARB hearing rules, evidence rules β captured from the agency’s published guidance, not a third-party summary.
- Cross-reference state and federal layer. Texas Tax Code citations, California Revenue and Taxation Code, Florida Statutes Ch. 192β200, IRS Pub. 530, VA exemption coordination β current and live.
- Editor sign-off. A second editor reviews end-to-end before publication, including a fresh check on the not-tax-advice and not-legal-advice notices.
Nothing on this site is auto-scraped. Nothing is generated from a stale database. Every contact is human-verified before publication and re-verified on a quarterly cycle, with heightened-review windows in the 60 days before each state’s primary protest deadline.
Texas County Appraisal Districts β The Most Distinct System in the Country
Texas operates a unique structure. The Property Tax Code (Tex. Tax Code Ch. 6) requires every Texas county to maintain a County Appraisal District (CAD) β a separate political subdivision governed by a Board of Directors selected by the taxing units in the county. The CAD employs a chief appraiser who is responsible for valuing all property in the county. An Appraisal Review Board (ARB), whose members are appointed by the local administrative district judge, hears protests. The process is more formal and more centralised than in most states. Major Texas CADs include:
| CAD | County (largest cities) | URL |
|---|---|---|
| Harris County Appraisal District (HCAD) | Harris (Houston) | hcad.org |
| Dallas Central Appraisal District (DCAD) | Dallas | dallascad.org |
| Tarrant Appraisal District (TAD) | Tarrant (Fort Worth, Arlington) | tad.org |
| Bexar Appraisal District | Bexar (San Antonio) | bcad.org |
| Travis Central Appraisal District (TCAD) | Travis (Austin) | traviscad.org |
| Collin Central Appraisal District (CCAD) | Collin (Plano, Frisco) | collincad.org |
| Denton Central Appraisal District | Denton | dentoncad.com |
| Fort Bend Central Appraisal District | Fort Bend | fbcad.org |
| Williamson Central Appraisal District (WCAD) | Williamson (Round Rock) | wcad.org |
| El Paso Central Appraisal District | El Paso | epcad.org |
California, Florida & Other State Frameworks
Outside Texas, the structure is different. California operates under Proposition 13 (Cal. Const. Art. XIIIA), which limits assessed value increases to 2% per year on most property and resets to fair market value only on transfer. The County Assessor determines value; the County Assessment Appeals Board hears appeals. The state coordinator is the California State Board of Equalization (boe.ca.gov).
Florida uses County Property Appraisers governed by Fla. Stat. Ch. 192β200. The TRIM (Truth in Millage) notice triggers the 25-day appeal window to the Value Adjustment Board (VAB). The state coordinator is the Florida Department of Revenue (floridarevenue.com/property).
Other states use varying frameworks. Most New England states assess at the city/town level rather than county. Pennsylvania assesses at county level but uses elected county Boards of Assessment Appeals. Tennessee uses County Property Assessors with state oversight from the Comptroller’s Division of Property Assessments. Each state’s framework is documented on the relevant county pages.
