How We Got Here
This Property's Value Over Time

Here's how this property's value has changed over the past 6 years.

This Property's Value vs. What It's Taxed On gap up to 20.0%

The top line is this property's certified market value. The bottom line is its taxable value — the number its tax bill is actually calculated from. The gap between them is real money: it's what an exemption or value-limitation adjustment is protecting this property from being taxed on.

This gap reflects a value-limitation adjustment reducing what's actually taxed below the certified market value — not a data error. Same figures as the certified values on record for this parcel.

Combined rate = the total of all this property's 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.
