County Property Tax is an independent educational website. We build free, fast calculators and plain-language reference pages about county property taxes in the United States: property tax calculators for Cook, Harris, Tarrant, Dallas, Travis, Bexar, Los Angeles, Orange, King and Maricopa counties, adopted tax rates by taxing unit, homestead, senior and disabled veteran exemptions, assessment ratios and caps such as California Prop 13 and the Texas 10% homestead cap, payment due dates and installments, and how to appeal an assessment.
What we do
- Adopted rates from the office that sets them. Every tax rate, assessment ratio and exemption amount on a county page comes from the county appraisal district, assessor, auditor-controller, treasurer or tax collector, or from the state revenue department or statute, and carries its tax year.
- Calculators you can check. Each result shows the math line by line (value, assessment ratio, exemptions, rate by taxing unit) and the engine is tested against official sample bills, such as the Cook County Treasurer's published example.
- Deadlines in one place. Payment due dates, installment rules and appeal windows are summarized from the county office and linked.
- No selling. We do not sell products, we do not link to sellers, and we do not accept payment for reviews or placements.
Who we are
County Property Tax is run by a small independent editorial team based in Türkiye. We are not affiliated with any county assessor, appraisal district, treasurer, tax collector, auditor-controller, board of review, state revenue department, the U.S. Census Bureau, or any tax consultant or appeal firm.
