How Your Bill Is Calculated
Your property tax bill is your assessed value, minus any exemptions, multiplied by the combined tax rate for your address. Here is a hypothetical example for a $500,000 home in Austin ISD with a homestead exemption filed.
- Assessed value: $500,000
- Homestead exemption, school portion: $500,000 minus $140,000 = $360,000 taxable value for AISD
- AISD school tax: $360,000 divided by 100 times $0.925200 = $3,330.72
- City of Austin tax: $500,000 divided by 100 times $0.574017 = $2,870.09
- Travis County tax: $500,000 divided by 100 times $0.375845 = $1,879.23
- ACC and Central Health: $500,000 divided by 100 times the combined $0.221423 = $1,107.12
- Hypothetical total: approximately $9,187 per year, or $766 per month in escrow
This example is hypothetical. Every input is stated so you can adjust for your situation. Your actual bill depends on the Travis Central Appraisal District’s assessed value, which may differ from the purchase price. Use the escrow shock test to model the exact bill at any address.
