Homestead Appraisal Cap Check

Texas limits how much your homestead's appraised value can rise each year, regardless of market value. This tool checks whether your appraisal district has gone over that limit.

Short answer: capped appraised value = min(market value, prior year's appraised value × 1.10 + new improvements). If your notice shows a value above that number, it's over the 10% cap under Tax Code §23.23.

Check your cap

Values

Prior year's appraised value ($)

Current year's market value ($)

Value of new improvements this year ($)

New improvements (an addition, a pool, etc.) are added on top of the 10% cap, not subject to it themselves.

Did this property have a homestead exemption as of January 1 of the prior year?

Yes

If not, the 10% cap does not apply to this year's value yet.

About the cap

The 10% cap applies only to a residence homestead's appraised value, not market value, and only once the exemption was in place as of January 1 of the prior year (Tax Code §23.23).
New improvements — a room addition, a pool, major new construction — are added to the capped value separately; they are not limited by the 10% rule in their first year.
Informational only: a separate 20% appraisal increase "circuit breaker" currently applies to most non-homestead real property valued at about $5 million or less (adjusted annually), for tax years 2024–2026 under Tax Code §23.231. It does not apply to homesteads and is not calculated by this tool.
