Texas homestead exemption in Bexar County: what you actually save

Last updated 2026-07-10

What is the Texas homestead exemption and how does Bexar County handle it?

The Texas homestead exemption removes a set dollar amount from your home's appraised value before the tax rate touches it. It's not a credit. It's not a percentage off your bill. It shrinks the taxable value your rate gets multiplied against. That distinction is the whole ballgame. A $100,000 exemption on a $400,000 home means you're taxed on $300,000, not $400,000.

Bexar County's appraisal district, BCAD (Bexar Appraisal District), runs exemptions for every taxing unit in the county: San Antonio ISD, North East ISD, Northside ISD, Alamo Colleges, and dozens of city and utility districts. Each unit sets its own rate. Your total tax bill is the sum of all of them. The exemption works at every layer.

Texas Property Tax Code Section 11.13 governs the framework ^[1]. After HB 3 passed in 2023, the mandatory school-district exemption jumped from $40,000 to $100,000 for most homestead owners ^[2]. That one change cut the average San Antonio homeowner's school taxes by roughly $1,000, give or take depending on the district's rate.

How much is the Bexar County homestead exemption worth in dollars?

The honest answer: it depends on which taxing unit you're in, because San Antonio's city exemption stacks differently than Converse's or Leon Valley's. But some pieces are locked in for every Bexar County homestead, and those are the ones you can bank on.

The state-mandated school exemption of $100,000 comes off the top of your appraised value for school taxes ^[2]. Say your home sits in San Antonio ISD. That district's 2024 M&O rate ran roughly $0.7892 per $100 of taxable value. A $100,000 exemption saves you about $789 on SAISD taxes alone, before any other unit's rate enters the picture.

The City of San Antonio offers an optional 20% exemption on the city portion of your taxes ^[3]. Bexar County itself offers a 20% exemption on the county portion. Both apply to appraised value after any absolute-dollar school exemptions, so the math chains together layer by layer.

Seniors (65+) and disabled residents get an extra $10,000 off the school-district value on top of the $100,000, which brings their school exemption to $110,000 ^[1]. They also get the strongest benefit in the whole Texas system: a school-tax freeze. It caps the dollar amount of school taxes at the level assessed in the year they first qualified. Values can climb all they want. The frozen bill holds.

Exemption Layer	Who Qualifies	Amount Off Taxable Value
School district (state-mandated)	All homestead owners	$100,000
School district (senior/disabled add-on)	Age 65+ or disabled	Additional $10,000
School tax freeze	Age 65+ or disabled	Bill capped at qualification-year level
City of San Antonio	All homestead owners in city limits	20% of appraised value
Bexar County	All homestead owners	20% of appraised value
Alamo Colleges District	All homestead owners	$5,000 (varies by year)

Other local units, like hospital districts and water districts, may add their own optional exemptions. BCAD publishes the full list at bcad.org ^[3].

Who qualifies for the Bexar County homestead exemption?

Texas Property Tax Code Section 11.13(a) entitles an individual to an exemption if the property is that individual's residence homestead on January 1 of the tax year ^[1]. Three things have to be true on that date.

You must own the property. Renters don't qualify. LLCs don't qualify. Trusts don't qualify unless they're structured as a qualifying trust under Section 11.13(j).

The property must be your principal residence, meaning you actually live there. A vacation home doesn't count. Neither does a rental you happen to own.

And you can hold only one homestead exemption in Texas at a time. If you already have one in Dallas County and you move to Bexar County, the old one has to come off before the new one takes full effect. The new homestead has to be your principal residence on January 1 of the year you're applying for.

Citizenship isn't a factor. Texas law imposes no citizenship requirement for the general homestead exemption. You need to own the home and live in it. That's it.

For the senior add-on ($10,000 plus the tax freeze), you must turn 65 during the tax year or already be 65 on January 1. For the disability exemption, you must meet the Social Security Administration's definition of disability ^[1]. BCAD accepts an SSA disability award letter as proof.

What is the filing deadline for the Bexar County homestead exemption?

April 30 is the standard deadline. Texas Property Tax Code Section 11.43(d) sets the general deadline at April 30 of the year you want the exemption for ^[8].

Miss it and you still have options. BCAD accepts late applications through December 31 for the current tax year, but the exemption comes with a 10% penalty on the amount of tax you would have saved by filing on time ^[8]. Real money. Worth avoiding.

Bought your home after January 1? You can still file for that tax year. SB 12 (2021) changed the old rule: buyers who close after January 1 can apply mid-year and receive a prorated exemption for that year, as long as the prior owner didn't already have a homestead exemption in place ^[10].

Seniors turning 65 during the year can apply any time that year and get the senior benefit for the whole year, more than from their birthday forward.

Once approved, you never refile. BCAD re-examines a homestead exemption only if you tell them something changed (you sold, you moved out) or if they flag the property for review. Otherwise it renews on its own as long as the home stays your principal residence.

How do you file Form 50-114 with BCAD?

Form 50-114, the Residence Homestead Exemption Application, is the Texas Comptroller's standard form that every county appraisal district uses ^[4]. BCAD takes it three ways: online through the portal at bcad.org, by mail, or in person at 411 N Frio Street, San Antonio, TX 78207.

Online is fastest. BCAD's e-file system hands you a confirmation number on the spot, and it's open year-round.

Have these ready before you start:

• Texas driver's license or Texas ID card showing your homestead address. This is a hard requirement. The address on your ID has to match the property address. If it doesn't, BCAD rejects the application until you update your license with the Texas DPS.
• Your vehicle registration, if it's registered at that address (BCAD may ask for it as backup, though it isn't always required).
• Your Social Security number (required on the form, not made public).
• For senior or disabled exemptions: proof of age or an SSA disability determination letter.
• For a trust-held property: a copy of the trust instrument showing you're a qualifying occupant-beneficiary.

BCAD processes most applications within 90 days. They mail a written notice approving or denying the exemption. If it's approved, you'll see the reduced taxable value on your next appraisal notice, usually mailed in April of the following year.

The Comptroller's Form 50-114 instructions state plainly that you must provide your Texas driver's license or state-issued ID card number and address ^[4]. Don't assume an out-of-state ID is close enough. It isn't.

What happens to the homestead exemption cap on appraised value increases?

This is a different thing from the exemption, but the two work together and most homeowners mix them up.

Texas Property Tax Code Section 11.13(d) limits how fast a homestead's appraised value can climb. Once a homestead exemption has been in place for a full year, BCAD can raise your taxable value by no more than 10% per year over the prior year's appraised value, no matter what the market does ^[1]. People call it the homestead cap, or the 10% cap.

Say your home is appraised at $350,000 this year with the exemption in place. BCAD cannot push your taxable appraised value above $385,000 next year, even if comparable sales say the home is now worth $420,000. The market value line on your notice might read $420,000. The capped value used for tax purposes stays at $385,000.

The cap resets to zero when you sell. The new owner starts fresh at full market value until they file their own exemption and finish a full tax year.

This is the biggest reason to file the moment you buy. Every year you wait is a year exposed to full market-value increases, and a year the cap doesn't build in your favor.

Other states run this differently. Florida uses a structure called Save Our Homes, which we break down in our piece on the florida homestead exemption.

What extra exemptions do seniors and disabled residents get in Bexar County?

Texas hands seniors and disabled homeowners two protections that go well past what everyone else gets.

First is the extra $10,000 school-district exemption stacked on the standard $100,000. A qualifying senior's school-district taxable value drops by $110,000 instead of $100,000 ^[1].

Second is the school-tax freeze, and it's the one that matters most over time. Once you qualify, the total dollar amount of school taxes you owe locks at that year's level. It can fall if rates drop or you pick up more exemptions. It can never rise as long as you stay in the home and keep qualifying. The freeze passes to a surviving spouse who is at least 55 and was living in the home when the qualified owner died ^[1].

Some Bexar County units offer optional local freezes for seniors. Not all do. The City of San Antonio offers one on the city portion.

Disabled veterans get a separate set of exemptions under Texas Property Tax Code Section 11.22. These run off the VA disability rating rather than a flat dollar amount, scaling from $5,000 off for a 10-29% rating up to a full exemption from all property taxes for veterans rated 100% or classified as unemployable ^[9]. A 100% disabled veteran pays zero property tax on a Texas homestead. Surviving spouses of veterans killed in action or who died of a service-connected disability qualify for the full exemption too ^[9].

Our guide on whether texas offers property tax relief for seniors covers the statewide picture in more depth.

What if BCAD denies your homestead exemption application?

Denials happen, and they're usually fixable. The common reasons: the address on your Texas ID doesn't match the property, a field on the form is blank, or BCAD doubts the home is your principal residence (this comes up with new construction and homes listed on short-term rental sites).

When BCAD denies your application, it has to send written notice. You then have 30 days from the date of that notice to file a written protest with the Bexar County Appraisal Review Board (ARB) ^[6]. The ARB is independent from BCAD. It hears disputes between owners and the appraisal district.

For a denied exemption (as opposed to a fight over market value), your protest should include a copy of your updated Texas driver's license with the correct address, utility bills in your name at the property, and voter registration at the address if you have it. Anything that shows you live there.

You can represent yourself at an ARB hearing. An exemption dispute isn't complicated. You're not arguing comparable sales or valuation methods. You're proving you live in the house.

If the ARB rules against you, you can appeal to district court within 60 days of the order ^[6]. That path means legal fees and rarely pays off for a simple exemption denial you can cure by updating your ID.

If your real problem is an inflated value rather than a denied exemption, that's a separate protest. To file it yourself without handing a firm a cut, our DIY appeal kit at TaxFightBack lays out the evidence you need.

For comparison, see how denton county homestead exemption appeals run, since that ARB process closely mirrors Bexar's.

How does the Bexar County homestead exemption interact with your total tax bill?

Your Bexar County tax bill isn't one number from one office. It's several bills from several taxing units printed on one statement. A San Antonio homeowner in Northside ISD might see charges from Northside ISD, Bexar County, the City of San Antonio, the Bexar County Hospital District, Alamo Colleges, and maybe a water or utility district. Each carries its own rate.

The exemption applies separately to each unit's math, and the units don't all adopt the same percentages. The $100,000 school exemption is mandatory for every school district. The 20% county exemption is Bexar County's voluntary choice. The city exemption is the City of San Antonio's voluntary choice.

Here's the math for a home appraised at $350,000 in the City of San Antonio within Northside ISD, using real published 2024 rates ^[7]:

Taxing Unit	Appraised Value	Exemption Applied	Taxable Value	Rate (per $100)	Tax Owed
Northside ISD	$350,000	$100,000 school	$250,000	~$0.9102	~$2,276
Bexar County	$350,000	20% = $70,000	$280,000	~$0.2763	~$774
City of San Antonio	$350,000	20% = $70,000	$280,000	~$0.3417	~$957
Bexar Co. Hospital Dist.	$350,000	varies	~$350,000	~$0.2722	~$953
Alamo Colleges	$350,000	$5,000	$345,000	~$0.0921	~$318
Total					~$5,278

Strip out the exemptions and that same home owes north of $7,200 across all units. The stacked exemptions save this hypothetical owner somewhere around $1,900 to $2,000 a year. Your real savings hinge on your specific units and the current year's rates, which BCAD posts at bcad.org ^[3].

Can you lose the homestead exemption and how do you reinstate it?

Yes, and BCAD audits homestead exemptions more often than owners expect.

You lose the exemption automatically the moment the property stops being your principal residence. You move out. You turn it into a rental. You sell it. You claim a homestead exemption somewhere else. Texas law requires you to notify BCAD within one year of any of these changes ^[1]. Keeping the exemption while you no longer qualify is tax fraud under Texas law, and it can trigger back taxes, penalties, and interest reaching back up to five years.

BCAD also cross-checks homestead exemptions against vehicle registration records, voter rolls, and business filings. If your car is registered at a different address, expect a letter asking you to prove residency. Answer fast, with documentation. BCAD usually gives 30 days to respond.

To reinstate a lost exemption, file a new Form 50-114 with updated documentation. If it dropped off because of a clerical issue or a temporary change that's now resolved, BCAD can sometimes reinstate it retroactively for the current year. Once more than a tax year has passed, that savings is generally gone.

One trap for new buyers: if the previous owner had a homestead exemption and you haven't filed your own, the exemption does not carry over to you. You start fresh.

Is your Bexar County assessed value still too high after the exemption?

The exemption cuts your taxable value. It does nothing about an inflated appraisal. Two separate problems.

Picture BCAD setting your home's market value at $420,000 while comparable sales in your neighborhood point to $360,000. The exemption knocks $100,000 off the $420,000 and leaves a taxable value of $320,000. Correct the market value to $360,000, and your taxable value after the same exemption falls to $260,000. That gap shows up on your bill.

You can protest your market value every single year. The Bexar County protest deadline is May 15, or 30 days after BCAD mails your appraisal notice, whichever is later ^[6]. Notices usually go out in April.

What wins a value protest: recent sales of comparable homes in your neighborhood that closed for less than your assessed value. BCAD's own data is public record and it's your starting point. Pull sales from BCAD's property search tool and deed records from the Bexar County Clerk.

Contingency firms take 25% to 40% of your first year's savings. On a $500 annual reduction, that's $125 to $200 out the door for filing a few forms. The TaxFightBack DIY appeal kit exists so you can do the same work and keep every dollar of the reduction.

Frequently asked questions

When is the deadline to file for the homestead exemption in Bexar County?

April 30 is the primary deadline for the tax year you want the exemption. BCAD accepts late applications through December 31 of that same year, but a 10% penalty on the tax savings may apply. Seniors qualifying for the first time at age 65 can file at any point during that year and still receive the full senior exemption.

How much does the Bexar County homestead exemption save you per year?

Most Bexar County homeowners save $1,500 to $2,500 a year across all taxing units combined. The mandatory $100,000 school-district exemption alone saves roughly $700 to $1,000 depending on your school district's rate. The Bexar County 20% exemption and City of San Antonio 20% exemption add several hundred dollars more on top.

Do you have to refile the Bexar County homestead exemption every year?

No. Once BCAD approves your homestead exemption, it renews automatically each year as long as the property stays your principal residence. You only need to act when something changes: you move, sell, or stop using it as your primary home. BCAD may occasionally send a verification letter if it flags your file for review.

What documents do I need to file for the homestead exemption with BCAD?

You need Form 50-114 (from bcad.org or the Texas Comptroller), a Texas driver's license or state ID showing the property's address, and your Social Security number. For senior or disability exemptions, add proof of age or an SSA disability award letter. The address on your Texas ID must match the property address exactly, or BCAD rejects the application.

Can a 100% disabled veteran get a full property tax exemption in Bexar County?

Yes. Texas Property Tax Code Section 11.22 exempts 100% disabled veterans from all property taxes on their homestead, regardless of the home's value. It also covers veterans rated as individually unemployable by the VA. Surviving spouses of veterans who died of service-connected disabilities or were killed in action qualify for the same full exemption.

Does the homestead exemption cap appraised value increases in Bexar County?

Yes. Once a homestead exemption has been in place for a full tax year, BCAD can raise your home's taxable appraised value by no more than 10% per year over the prior year's capped value, no matter how much the market rises. The cap resets when the property sells, so the new owner starts at full market value until they file their own exemption.

What is the senior tax freeze for Bexar County homeowners?

Homeowners who are 65 or older (or disabled) qualify for a school-tax freeze. BCAD locks the dollar amount of school district taxes you owe at the level you paid in the year you first qualified. The bill can drop but never rise while you stay in the home. The freeze transfers to a surviving spouse who is at least 55 years old.

Can I apply for the Bexar County homestead exemption online?

Yes. BCAD's website at bcad.org has an online e-file portal for Form 50-114. You confirm your Texas ID information and get a confirmation number immediately. Online filing is the fastest method. Mail and in-person filing at 411 N Frio Street are also accepted through the April 30 deadline.

What happens if my Texas driver's license address doesn't match my property address?

BCAD rejects your homestead exemption application. The Texas Comptroller's Form 50-114 instructions require your Texas ID to show the homestead property's address. Update your address with the Texas Department of Public Safety at dps.texas.gov before filing, then submit. There's no workaround. It's a hard requirement.

Can a trust or LLC claim the Bexar County homestead exemption?

Generally, no. An LLC cannot claim a homestead exemption. A qualifying trust can, under Texas Property Tax Code Section 11.13(j), if the individual beneficiary uses the property as their principal residence and would otherwise qualify. You'll need to submit the trust instrument with your application so BCAD can verify the structure meets the legal requirements.

How do I protest my Bexar County appraisal if I think my home is overvalued?

File a Notice of Protest with BCAD by May 15 or 30 days after your appraisal notice is mailed, whichever is later. BCAD schedules an informal hearing first. Bring recent sales of comparable homes that sold for less than your assessed value. If the informal talk fails, you go before the Bexar County ARB for a formal hearing. You can do all of this yourself.

What is the Alamo Colleges homestead exemption in Bexar County?

The Alamo Colleges District offers a homestead exemption to qualifying residential owners in Bexar County. The amount has varied; in recent tax years it has been $5,000 off the taxable value for the Alamo Colleges rate. Check BCAD's current exemption schedule at bcad.org for this year's amount, since taxing units can change their optional exemptions annually.

How long does BCAD take to process a homestead exemption application?

BCAD's standard window is up to 90 days from receipt of a complete application. File online with all the required information and you may see the exemption reflected sooner. You'll get a written approval or denial by mail. If 90 days pass with no word, call BCAD at (210) 224-2432 with your confirmation number.

What is the difference between the homestead exemption and the homestead cap in Texas?

The exemption reduces your taxable value by a set dollar amount (for example, $100,000 for school taxes). The cap limits how fast that already-reduced value can climb, capped at 10% per year. Both apply automatically once your exemption is approved, but they do different jobs. The exemption reduces the base. The cap controls how fast the base grows.
