About Us

The Two-Office Structure — Most U.S. States

In most U.S. states, property taxation involves two separate county offices:

The two offices operate independently. The Assessor sets the value; the Tax Collector / Treasurer bills and collects. Disputes over your property’s value go to the Assessor (and from there to a Board of Equalization, Board of Review, Property Tax Appeal Board, or equivalent body, depending on the state). Disputes over your bill, payment plan, or delinquency status go to the Tax Collector / Treasurer.

The Combined-Office Variation — Texas

Texas is the most notable exception to the two-office structure. In every Texas county, the property-tax system has its own distinct structure:

• The Central Appraisal District (CAD) — determines the appraised value of all property in the county under the Texas Property Tax Code (Title 1, Subtitle E of the Texas Tax Code). One CAD per county, all 254 Texas counties. Examples: Harris Central Appraisal District (HCAD), Dallas Central Appraisal District (DCAD), Tarrant Appraisal District (TAD), Bexar Appraisal District (BCAD), Travis Central Appraisal District (TCAD). Supervised by the Texas Comptroller of Public Accounts Property Tax Assistance Division (PTAD) under Tex. Tax Code §5.
• The County Tax Assessor-Collector — a single combined office in each Texas county that issues the property tax bill and collects payments for every taxing unit operating in the county (school districts, cities, the county, special districts, ESDs, hospital districts, MUDs). The Tax Assessor-Collector also handles motor-vehicle registration, voter registration, and (in some counties) beer/wine permits.
• The Appraisal Review Board (ARB) — separately appointed citizens under Tex. Tax Code §6.41 who hear protests against the CAD’s valuations under §41.41, with the unforgiving §41.44 deadline (May 15 or 30 days after Notice of Appraised Value).

Throughout the Texas section of this site, we use the term “County Tax Assessor-Collector” to mean the Texas combined billing/collection office, and we distinguish it carefully from the CAD which handles valuation. If you are a Texas property owner, you typically interact with the CAD for value disputes, exemption applications, and ARB protests, and with the County Tax Assessor-Collector for bills, payments, payment plans, and delinquency.

Terminology Variation — State by State

The exact title matters because search results are organised under different offices in different states — searching “Cook County Tax Assessor” returns different results than “Cook County Treasurer” or “Cook County Assessor’s Office,” even though all three are different aspects of the same property-tax system.

What Sets countytaxassessor.org/ Apart — The Manual-Verification Standard

U.S. county tax administration is local. Each of the 3,143 U.S. counties (and county equivalents) has its own forms, deadlines, online portals, and procedures. National aggregators that pull data automatically frequently break — counties redesign portals, exemption forms change after legislative sessions, deadlines shift, and assessor offices change leadership.

Every county guide on countytaxassessor.org/ is verified by a human editor against the county's own published page and cross-checked against the state Department of Revenue or Department of Taxation reference. We do not auto-scrape. We do not pull from third-party data brokers. Every county URL is human-clicked before publication. Every assessor portal walkthrough is performed on the live county website by an editor.

What This Site Is For

countytaxassessor.org/ is the plain-English, structurally complete reference for understanding and using U.S. county tax assessor and tax collector offices. We explain who does what, where to file what, and how to get the right answer from the right office — without making you wade through state-statute language or jargon. Every county guide on the site lists the official county Assessor and Tax Collector / Treasurer pages, verified property-search portal URLs, exemption application procedures (with deadlines), appeal procedures (with the controlling state statute and deadline), bill payment procedures, GIS / parcel-map portals where available, and each office's address, hours, phone, and main email.

We are completely independent. We are not affiliated with any U.S. county office, state Department of Revenue or Department of Taxation, the International Association of Assessing Officers (IAAO), the Appraisal Foundation, the National Association of Counties (NACo), or any commercial property-records aggregator, title company, or real estate platform. We do not sell property records. We do not file appeals. We do not provide tenant-screening, background-check, or any FCRA-regulated services. Every property record is held by the county Assessor or Tax Collector — the official path is always the county’s own portal.

The Eight Categories of County Tax Information We Cover

What You’ll Find on Each County Page

• County name and state — jurisdiction context
• Official county Assessor name and URL — verified live, updated quarterly
• Official county Tax Collector / Treasurer name and URL — verified live
• Property-search portal URL — on the Assessor side
• Bill-lookup / pay-online URL — on the Tax Collector / Treasurer side
• GIS / parcel-map URL — where the county provides one
• Exemption procedures — residence homestead, over-65 / senior, disabled, disabled veteran, surviving spouse — with state-specific deadlines
• Assessment appeal procedure — Board of Equalization / Board of Review / ARB / equivalent, with the state-specific deadline
• Payment-plan options — quarterly, monthly, partial, deferral programs
• Delinquency procedures — penalty/interest accrual, tax-certificate sales, tax deeds, redemption periods
• Both offices’ address, hours, phone
• State Department of Revenue / Department of Taxation link — state oversight reference
• FAQ — questions specific to that county’s procedures

How We Find and Verify — The Eight-Step Process

1. Identify the right authoritative source. The county’s official Assessor and the county’s official Tax Collector / Treasurer, plus the state Department of Revenue or Department of Taxation, plus the state’s controlling statutes.
2. Verify the county URLs are live. A human editor clicks every link before publication — both the Assessor side and the Tax Collector / Treasurer side.
3. Walk through the property-search portal. An editor performs a real property search on the Assessor’s portal to confirm the walkthrough matches the current interface.
4. Walk through the bill-lookup / pay-online portal. An editor performs a real bill lookup on the Tax Collector’s portal.
5. Cross-check exemption procedures and deadlines. Against the county’s published exemption forms and state reference.
6. Cross-check the assessment-appeal procedure. Against the county’s published appeal forms and the state’s controlling statute.
7. Dial-test both offices’ main phone numbers. Quarterly cycle.
8. Editor sign-off. A second editor reviews end-to-end, including a fresh check on the FCRA non-CRA notice and the “verify with county before relying” caveat.

• State Boards of Equalization or State Tax Commissions — for inter-county equalisation (California, Wyoming, others)
• International Association of Assessing Officers (IAAO) — professional standards including the IAAO Standard on Mass Appraisal of Real Property, Standard on Verification and Adjustment of Sales, Standard on Ratio Studies, Standard on Property Tax Policy, Standard on Professional Designations
• Uniform Standards of Professional Appraisal Practice (USPAP) — administered by the Appraisal Foundation
