Understanding your property tax bill starts with knowing how each taxing unit contributes to your total rate.
Your county appraisal district determines your property's taxable value each year. In Texas this is the appraised market value (with homestead exemptions applied). In California, Proposition 13 caps annual increases at 2% unless the property changes ownership.
Each taxing unit adopts an annual tax rate expressed as dollars per $100 of assessed value in Texas, or as a percentage in California. Your total rate is the sum of every applicable unit's rate — county, school district, city, and all special districts.
Annual Tax = (Assessed Value ÷ 100) × Total Rate (TX) or Assessed Value × Total Rate (CA). A $400,000 home in a 2.25% rate area pays $9,000/year. The TaxDrop calculator shows this estimate instantly after you enter your address.
A taxing unit is any government entity authorized by state law to levy property taxes on real property within its jurisdiction. Most homeowners are subject to 4 to 7 overlapping taxing units simultaneously — meaning each unit independently sets its own rate, and you pay all of them.
The most common taxing units are: the county (funds courts, roads, and county services), the independent school district (ISD) (typically the largest single component, funding K–12 public education), the city or municipality (funds police, fire, parks, and local infrastructure), and various special districts such as Municipal Utility Districts (MUDs), Hospital Districts, Community College Districts, and Emergency Services Districts.
TaxDrop's calculator identifies every taxing unit applicable to your specific address and displays each unit's individual rate, annual dollar cost, and percentage share of your total tax bill.
TaxDrop currently serves homeowners in Texas and California — the two largest property tax markets in the United States by total assessed value.
Texas has no state income tax, making property taxes the primary revenue source for local governments. The state's effective property tax rate averages 1.6%–2.8%, among the highest in the nation. Texas homeowners can file an annual property tax protest with their county appraisal district — a right that can result in significant savings.
Major Texas markets covered: Houston (Harris County), Dallas (Dallas County), Austin (Travis County), San Antonio (Bexar County), Fort Worth (Tarrant County), and all 254 Texas counties.
California's property taxes are governed by Proposition 13 (1978), which caps the base tax rate at 1% of assessed value and limits annual assessment increases to 2% until the property is sold. Voter-approved general obligation bonds add 0.10%–0.50% on top, bringing effective rates to 1.1%–1.5% in most counties.
Major California markets covered: Los Angeles County, San Diego County, Orange County, Santa Clara County (Silicon Valley), Alameda County (Oakland/Berkeley), and all 58 California counties.
