Your Homestead Exemption When You Sell in San Antonio: What Transfers, What Resets, and What the Buyer Has to Do

When you sell your San Antonio home, your homestead exemption does not transfer to the buyer. It was yours, tied to your ownership and occupancy as of January 1 of the tax year, and it ends when the property stops being your principal residence. The buyer does not inherit it. They have to file their own, and in the meantime the appraised value the buyer gets taxed on will almost always jump — sometimes significantly — because the 10% homestead cap resets at sale.

That reset, not the exemption itself, is where most of the money lives. Understanding how the Bexar Appraisal District (BCAD) handles the handoff is what keeps buyers from sticker shock in October and keeps sellers from overpaying at closing.

Who pays the property tax for the year you sell

Texas taxes are assessed for the whole calendar year based on who owned and qualified for exemptions on January 1. If you owned your Stone Oak house on January 1 and had your homestead exemption on file, that exemption applies to the full year's tax bill — even if you sell in June.

At closing, the TREC 1-4 Family Resale Contract (currently TREC 20-17) handles this in Paragraph 13: taxes are prorated as of the closing date. The title company debits the seller for their portion of the estimated annual tax (January 1 through closing) and credits the buyer, who then pays the full bill in October or later. The buyer gets the benefit of your exemption for that year because the tax statement is based on January 1 status.

This is why the closing year's tax bill often looks reasonable and the second year is the one that hurts.

The 10% homestead cap and why it resets

Under Texas Tax Code § 23.23, a homesteaded property's appraised value cannot increase more than 10% per year (plus the value of new improvements). If you've owned a home in 78209 or 78023 for seven or eight years, your appraised value is probably well below market. The cap has been doing a lot of quiet work.

The moment the property sells, that cap is gone. For the tax year following the sale, BCAD will reappraise the property at market value — which, for a home that just sold, is essentially the sale price. A buyer who pays $525,000 for a house that was appraised at $380,000 under the prior owner's cap is going to see the appraised value jump to roughly sale price the next January. The exemption the buyer files will shave some off, but it will not undo the reset.

Tell buyers this up front. A $145,000 jump in appraised value at Bexar County's combined tax rate can easily translate to $3,500+ in additional annual tax, and buyers routinely underwrite their mortgage escrow using the seller's current tax figure pulled from BCAD's public search. That number is wrong for them.

When the buyer can file their exemption

This rule changed in 2022 and a lot of people still operate on the old version.

Old rule: Buyer had to own and occupy on January 1 to claim the homestead exemption for that tax year. If you closed January 15, you waited almost a full year.

Current rule (post-SB 8, 2022): A buyer can file a homestead exemption in the year they acquire the property, as long as they occupy it as their principal residence and no one else claimed a homestead on the property earlier in the same tax year. The exemption is prorated from the date of qualification.

Practically, that means a buyer who closes on a Converse home in March and moves in can file Form 50-114 with BCAD shortly after and get a partial-year exemption for the current tax year, plus the full exemption going forward. The general deadline is still April 30 for a full-year exemption, but late applications are accepted up to two years after the delinquency date under § 11.431.

Buyers should also know: filing is free. BCAD does not charge. Any mailer offering to file the exemption for a fee is junk — throw it out.

The over-65 or disabled tax ceiling — this is where sellers do get something

If you are 65 or older, or disabled, and you had the over-65 exemption on your San Antonio home, you also had a school district tax ceiling under Tax Code § 11.26. Your school taxes were frozen at the amount the year you qualified.

That ceiling does not transfer to the buyer. The buyer, unless they are also 65+ or disabled, pays full school taxes on the reset appraised value.

But the ceiling does transfer to you. Under § 11.26(h), you can carry the percentage of tax savings to your next Texas homestead. You request a Tax Ceiling Transfer Certificate from BCAD (or the appraisal district where your old home sat), and you hand it to the appraisal district where your new home sits. The new district recalculates your school tax ceiling so you get the same percentage of savings on the new property.

Sellers moving from a paid-off house near Woodlawn Lake to a smaller place in Boerne or Schertz routinely leave this money on the table because they don't ask for the certificate. Ask.

What the seller needs to do about the exemption itself

Nothing, usually. When the deed records and BCAD's ownership data updates, the exemption tied to the old owner comes off automatically for the following tax year. You do not need to file a removal.

Two exceptions worth flagging:

• You moved out before closing and the property sat vacant or became a rental. Technically your homestead ended when you stopped occupying it as principal residence. If BCAD catches a gap — say, you homesteaded the property January 1 but actually moved to Austin in November of the prior year — they can reverse the exemption. Rare, but it happens on audited files.
• You're buying your next home before selling the old one. You can only have one homestead in Texas at a time. File the new exemption when you move in and surrender the old one. BCAD will ask which is your principal residence.

What most people get wrong

• Assuming the buyer's taxes will match the seller's BCAD figure. They won't, starting the year after closing. Run the buyer's escrow estimate off the likely reset — sale price minus the standard homestead exemption amount — at the current combined rate for that taxing jurisdiction.
• Thinking the homestead exemption 'transfers' with the house. It doesn't. It's tied to the owner-occupant. The buyer files their own.
• Missing the SB 8 mid-year filing window. Buyers still wait until the next January because that's what their parents did. File as soon as you occupy.
• Forgetting the over-65 ceiling transfer certificate. Seniors downsizing within Texas should always request one from the origin appraisal district before closing the next purchase.
• Letting a paid mailer file Form 50-114 for a fee. BCAD takes the form directly, online, for free. Anyone charging $45 to 'process your homestead' is running a low-grade scam that's been circulating in Bexar County mailboxes for years.
• Confusing the homestead exemption with the homestead cap. The exemption is a dollar reduction off appraised value. The cap is a 10% annual increase limit. The buyer gets the exemption once they file. The cap starts fresh and needs a full year of qualification before it kicks in — the first year after purchase, there's no cap protection.

Double-check the closing statement

Before you sign at the title company, look at the tax proration line. It should reflect the current year's tax with your exemptions applied, not a worst-case estimate. If the title company used an un-exempted figure, you're overpaying the buyer at closing by hundreds or low thousands. A quick pull from BCAD's property search confirms the right number. Title companies generally get this right, but 'generally' isn't 'always,' and it's your money until you sign.

For consequential questions — an over-65 ceiling transfer across county lines, a disputed exemption reversal, or a sale that straddles a January 1 — talk to a Texas-licensed property tax consultant or a real estate attorney before closing, not after.
