Why it matters in a transaction
Appraised value resets every January 1, and the homestead cap protecting a long-time owner does not transfer on sale. The next appraisal can move toward the purchase price.
Texas is a non-disclosure state, so appraisal districts estimate market value without seeing sale prices. Estimates can be wrong — and wrong in ways that are provable.
Voters approved a higher school homestead exemption in November 2025 ($140,000, up from $100,000), plus an extra $60,000 for homeowners 65 and older or disabled. A new owner still has to be sure the exemption is on the account.
In most cases a protest is due by May 15 or 30 days after the appraisal district mails its notice, whichever is later. Miss it and the year is gone.
How agents use it
Walk in knowing the county's number. See the subject property's value history, spikes, and component math before the seller brings it up — and show a seller you did the homework.
Check an address's appraisal history and red flags before the offer. Give buyers a straight talk on carrying costs, and flag a property whose appraisal looks out of line.
Send new owners to a first-year check: is the homestead exemption in place, and is the new appraisal defensible? Help your client make the first May 15 count.
Protest season is a reason to contact every past client with something genuinely useful. Be the agent who showed up with their tax numbers, not just a closing gift.

Seven independent forensic checks on the property's numbers.
A clear verdict and, if warranted, the evidence to file a protest.
A home's appraised value is set every January 1, and the seller's capped value does not transfer to the buyer. The sale price is evidence of market value, so the next appraisal can move toward what the buyer paid. The tax bill on a listing sheet may not be the bill a buyer ends up paying.
Yes. Texas property owners can protest their appraisal to the appraisal review board. In most cases the deadline is May 15 or 30 days after the appraisal district mails its notice, whichever is later.
