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.
