How We Got Here
Your Home's Value Over Time

Here's how your home's value has changed over the past 6 years.

Your Home's Value vs. What You're Taxed On gap up to 82.0%

The top line is your home's certified market value. The bottom line is your taxable value — the number your tax bill is actually calculated from. The gap between them is real money: it's what your homestead exemption and value-growth cap are protecting you from being taxed on.

This gap is why your tax bill is lower than a straight percentage of your home's market value would suggest — your homestead exemption and the 10% annual cap on taxable-value growth are doing real work here. Same figures as the certified values on record for this parcel.

Combined rate = the total of all your taxing entities' rates that year. Years marked “Verified” are confirmed directly from the Travis County Tax Office. Years marked “Partial” are reconstructed from portal payment receipts or incomplete billing records and may not reflect every adjustment. Where no billing record exists for a year, an estimate computed from that year's certified taxable value × combined rate may be shown instead (marked “Computed”) — not an actual billed amount.

Estimate only. The appraisal district sets value as of Jan 1 (not at sale price). A sale is strong evidence of market value and is typically reflected in the next Jan 1 valuation. Taxing units set rates annually. Modeled from government data — not a legal or tax opinion.
