This year: ~$1,762/yr from filing — based on the school district's $140,000 mandatory exemption, plus the confirmed 20% local-option exemption ($5,000 min) from Travis County, Travis Central Health, at your current assessed value and 2025 rates.
Other entities may offer unmodeled optional exemptions. Modeled estimate, not a verified figure — separate from any real exemption shown elsewhere on this page.
Your home has $4,957.87 in unpaid property taxes on record. Delinquent taxes become a lien on the property and transfer to the buyer at closing unless negotiated otherwise.
As of June 20, 2026 — Travis County Tax Office snapshot. This balance may have grown since then due to ongoing statutory penalty and interest (Tax Code §33.01); verify the exact current amount with the Travis County Tax Office ↗ before relying on it.
Here's how your home's value has changed over the past 6 years.
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.

Your home's value is lower than the typical home in Travis County (county median: $479,535).
Because property taxes are based on value, your tax bill is likely lower than similar homes.
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.
