Key Takeaways

• New construction property taxes in San Antonio often start low and jump once the finished home is appraised, so budget from the full value.
• New-build buyers can usually file for a prorated homestead exemption in the purchase year, and active duty members can request a waiver when their license address does not match.
• The 10% homestead cap does not limit the first full appraisal, so check the value and protest on time, even from another duty station.
• Review your first escrow analysis closely and confirm your exemption shows on the tax bill.

The builder’s payment sheet looks fine, and so does your first mortgage statement. Then the escrow analysis arrives about a year later, and your payment jumps because the tax bill has finally caught up with the house. Planning for new construction property taxes in San Antonio before you sign is how you keep that first-year trap from landing on your family.

The trap comes from how Texas taxes homes that are still being built, so it shows up on new builds near Joint Base San Antonio (JBSA) in a way it rarely does on resale homes. Before you tour any of the new construction homes near JBSA, it helps to know which steps after closing keep the bill under control.

A permanent change of station (PCS) makes those steps harder to time, since you may close from out of state, carry a license from another state, or get new orders before the first full appraisal. Each of those situations can be managed, whether you buy in Cibolo, Schertz, or on the far west side, as long as you know the rules ahead of time.

How New Construction Property Taxes in San Antonio Play Out

The first two tax years on a new build follow a pattern, and a little context makes the later steps easier to follow:

The Lot-Only First Bill

A new build’s first tax bill often covers only the lot or a partly built house, because Texas appraisal districts value property as it stands on January 1, though methods vary by district. Buyers comparing new builds near Lackland can see how that lot-only bill plays out over the first two years, and the pattern holds across San Antonio.

The Year-Two Escrow Gap

Escrow set from that lower first bill can come up short once the finished home is taxed, which usually means a higher payment in year two. How large the gap gets depends on the finished value, your tax rates, your exemptions, and your servicer’s escrow policies.

The Closing-Year Proration

At closing, the year’s taxes are usually prorated between you and the builder based on the days each of you owned the property, often using an estimate or the prior year’s bill. On a new build, that estimate may reflect only the lot, so the figure on your settlement statement can understate a full year. Many contracts call for the parties to adjust the proration once the actual bill is available, but builder contracts set their own terms, so ask your title company how yours handles it.

Filing the Homestead Exemption on a New Build

The homestead exemption is one of the few tax levers a buyer controls, and the filing details matter even more for military buyers:

Timing the Application After Closing

Since 2022, Texas law has let a buyer who acquires a home after January 1 receive the homestead exemption for the rest of that year, prorated from the date they qualify, as long as the previous owner did not have the same exemption that year. New construction usually fits, because the builder does not claim a homestead on the property. You qualify once you own the home and live in it as your principal residence.

Close on a finished home in June, move in that month, and the exemption can generally cover the rest of that year from the date you qualified. These rules come from state law, which the legislature can change, and your appraisal district decides when you qualify.

You apply on Form 50-114 with the appraisal district for the county where the home sits, not with the state. For a purchase-year exemption, the application is generally due before the first anniversary of the date you acquired the home, and in many cases a late application can be filed up to two years after the tax delinquency date. Deadlines and processing times are set by law and by each district, so file as soon as you move in.

When you weigh new construction versus resale near JBSA, disabled veteran exemptions can change the math a great deal, and they require a separate application. Eligibility is set by state law, can change, and is confirmed by the appraisal district.

Matching the Address on Your License

Form 50-114 asks for a copy of your Texas driver’s license or state ID, and the address on it generally must match the home you are claiming. Service members who keep a license from another state, or who have not updated a Texas license since closing, may find that an application without a matching address is denied or delayed. Updating your license with the Texas Department of Public Safety, where that fits your situation, is the simplest fix. The Comptroller sets the form’s requirements and can update them, so use the current version from your appraisal district.

Using the Active Duty Waiver

The form includes a waiver for active duty U.S. armed services members and their spouses. You can ask the chief appraiser to waive the address match by attaching a copy of your military ID, or your spouse’s, and a copy of a utility bill for the home in your name or your spouse’s name. Putting the electric or water account in your name at closing makes that bill easy to produce.

The waiver is up to the chief appraiser, so confirm current requirements with your appraisal district before you file. Veterans who are no longer on active duty do not fall under this waiver, so updating the license is the path for them.

Checking That the Exemption Took Effect

Filing is not the same as approval. Approval times vary by appraisal district, so check the district’s online record for your property and look for the homestead exemption on your tax statement in the fall. For a purchase-year exemption approved after the bill was calculated, current state law requires the tax office to send a corrected bill, or a refund if you already paid. Catching a missing exemption early is still far easier than unwinding a higher bill after your escrow has already been recalculated.

How the 10% Homestead Cap Treats a New Build

Texas limits how fast a homestead’s appraised value can rise, but the timing of that limit works against new-build owners at first:

The Start Date for the Cap

Under the Texas Tax Code as it reads today, the 10% limit on yearly increases in a homestead’s appraised value takes effect on January 1 of the tax year after the first year you qualify the home for the homestead exemption.

Buyers who take the purchase-year exemption are treated as first qualifying on January 1 of the following year, so a home bought and occupied in 2026 would generally not fall under the cap until the 2028 tax year. The 2027 appraisal, often the first one to show the finished house, is not limited by it, so confirm your dates with the appraisal district.

The Full Value of New Improvements

Even once the cap starts, current law lets the appraisal district add the market value of new improvements on top of the capped amount. A house finished after the last appraisal counts as a new improvement. That is why a home taxed as a lot one year can be taxed at close to its full value the next, with the cap doing little to slow the jump.

The Protection in Later Years

After the finished home is on the roll, the cap generally holds yearly increases in its appraised value to 10% plus any new improvements, as long as you keep the homestead exemption. Your market value can still rise faster, and the limit ends when the home stops qualifying or changes hands. The legislature can change these rules, so confirm how they apply with the appraisal district.

Protesting the First Full Appraisal While Away on Orders

The first full appraisal is often the one worth checking most closely, and distance does not have to stop you:

Watching for the Spring Value Notice

Appraisal districts usually mail notices of appraised value in the spring. The usual protest deadline is May 15 or 30 days after the notice was mailed, whichever is later, and it moves to the next business day when it falls on a weekend or holiday. For 2026, May 15 fell on a Friday, and in 2027 it falls on a Saturday, which moves the usual deadline to the following Monday.

Deadlines are set by state law and can change, and your notice shows the date that applies to you. Keep your mailing address current with the district so the notice reaches you wherever your orders take you.

Late protests can be allowed for good cause, but the appraisal review board decides what counts, and late protests are not accepted after it approves the appraisal records for the year. File on time rather than counting on an exception.

Filing the Protest Online

The Bexar Appraisal District accepts protests through its online services portal, and the notice of protest form can also be filed by mail or in person. Setting up your online account soon after closing saves time when the notice arrives, especially across time zones. Online tools and filing options can change, and other counties offer their own, so check with the district where your home sits.

Presenting Evidence From Another Duty Station

You do not have to appear in person. Under the Bexar Appraisal District protest procedures, you can present your case by phone, by videoconference, or by written affidavit using Comptroller Form 50-283, as long as you request the hearing type no later than the 10th day before your hearing. The appraisal review board sets its hearing procedures, which can change from year to year.

Recent sales of similar homes, photos, and any issues the district may not know about make the strongest evidence. Your settlement statement shows what you paid, which can help when the appraised value lands above your purchase price. I protest the appraisals on my own properties most years. Results depend on the evidence and the board’s review, so there is no guarantee of a lower value.

Appointing Someone to Act for You

Texas law also lets you designate an agent to handle a protest for you, using the Comptroller’s appointment of agent form. That can help when a deployment or training schedule overlaps the hearing season. Agent rules and fees vary, so read the terms before you sign one.

Handling the First Escrow Analysis on a New Build

The year-two escrow letter does not have to be a surprise. Federal rules shape what your servicer can do, and a few checks keep the numbers honest:

The Annual Escrow Statement

Your servicer reviews the escrow account each year and sends an annual statement within 30 days after the end of the escrow computation year. It shows what was paid in and out, the projected bills for the next year, and how any shortage or surplus will be handled. Compare the tax figure on that statement with your actual tax bill before you accept the new payment. These timelines come from federal rules, and each servicer’s schedule can differ within them.

The Shortage and Surplus Rules

Under federal rules, a shortage of at least one month’s escrow payment can either be left in the account or repaid in equal monthly amounts over at least 12 months. Servicers can also keep a cushion of up to one-sixth of the year’s expected payments. Some borrowers prefer to pay a shortage down sooner, so ask your servicer what it allows. When an analysis shows a surplus of $50 or more and your payments are current, federal rules generally require the servicer to refund it within 30 days. Federal escrow rules can be updated, and servicer practices vary within them.

The Exemption Check Before the Analysis

An escrow analysis is only as accurate as the tax bill behind it. Check that your homestead exemption and any disabled veteran exemption appear on the bill before the servicer runs its numbers. When a corrected bill arrives later, ask the servicer whether it will run a new analysis. Practices vary by servicer within federal rules, so get its answer in writing.

For families budgeting around a Basic Allowance for Housing (BAH), the payment after that first analysis is the one that matters, and BAH rates reset each year based on pay grade and dependency status. Before you sign for any new build, scroll through the homes within your BAH with the full-value tax figure in mind.

What Happens to the Homestead Exemption After Your Next PCS

Military moves raise a question most civilian owners never face, and the answer depends on where you live next:

Leaving the Home for a New Duty Station

Texas lets a home keep its homestead status during a temporary absence when the owner does not establish a different principal residence and intends to return. For most owners, that absence must be under two years, but the two-year limit does not apply to owners in military service inside or outside the United States.

The key condition is still that you do not set up a different principal residence somewhere else, and each appraisal district applies the rule to your facts, so confirm how it views your move. Before you leave, save your property ID and online account login so you can check the account from any duty station.

Renting the Home to a Tenant

Renting out the San Antonio home adds a wrinkle. The homestead exemption is tied to your principal residence, and a home leased to a tenant may no longer qualify, depending on how the appraisal district views your absence. The law does not spell out every PCS scenario, such as living in base housing at the next station, so ask the appraisal district how it treats your situation before you assume the exemption stays. As someone who owns rentals, I would run rental numbers on the full, non-homestead tax bill.

Buying at Your Next Duty Station

Buying and moving into a home at your next duty station generally establishes a different principal residence, and you can receive only one homestead exemption in a tax year. At that point, the San Antonio home typically stops qualifying, and the cap goes with it. Let the appraisal district know when the home no longer qualifies, and talk with a tax professional before you count on any rental return.

Avoiding the First-Year Trap on Your San Antonio New Build

The trap only works when the tax bill catches you off guard. You now know when to file the homestead exemption, how to handle a license from another state, why the cap waits a year, how to protest from wherever the military sends you, and what to look for in the first escrow letter. Walk into closing with that plan and a Military Relocation Specialist who knows how new builds are taxed, and the year-two letter becomes a number you already expected.

Your family can enjoy the new house without dreading the mailbox, because the real cost of owning it was part of the plan from day one.

Frequently Asked Questions (FAQs)

Can I file a homestead exemption the same year I buy a new build in San Antonio?

Generally, yes. Texas law lets a buyer who acquires a home after January 1 receive the exemption for the rest of that year, prorated, when the previous owner did not have the same exemption, which usually includes new construction. Apply with your county appraisal district, and confirm current deadlines with the district.

What if my driver’s license shows an address from another state?

The homestead application generally requires a Texas license or ID with an address that matches the home. Active duty members and their spouses can ask the chief appraiser to waive that match by attaching a copy of a military ID and a utility bill for the home in their name or their spouse’s name. The waiver is at the chief appraiser’s discretion, so check with your district.

Does the 10% homestead cap apply to my first full appraisal?

Usually not in a helpful way. The cap takes effect on January 1 of the tax year after the first year you qualify, and buyers who claim the purchase-year exemption are treated as first qualifying the following January, so the first full appraisal of a new build is usually not capped. The market value of new improvements can also be added on top of the cap, and these rules can change.

Can I protest my property taxes while stationed outside Texas?

Yes. The Bexar Appraisal District lets owners file online and present evidence by phone, by video, or by written affidavit, and Texas law lets you appoint an agent. The usual deadline is May 15 or 30 days after the notice was mailed, whichever is later, and procedures can change, so follow your notice and the district’s current instructions.

At JBSA Homes, I help buyers plan these tax steps around their orders and timeline before they leave San Antonio.

When are property taxes due in Bexar County?

Bexar County tax bills generally go out in the fall and are due by January 31, and an escrow account, if you have one, usually pays them for you. Payment dates can shift, so go by the date on your statement. Check the statement anyway to confirm the value and your exemptions, since those numbers feed your next escrow analysis.

What should I check on my first escrow analysis?

Compare the tax figure with your actual bill, confirm your exemptions are on that bill, and look at how any shortage will be repaid. Under federal rules, a shortage of at least one month’s payment can be spread over at least 12 months. Ask your servicer about its own practices.

Do I keep my homestead exemption if I PCS and rent out my house?

It depends. Texas lets military owners stay away longer than two years without losing the homestead, but only if they do not establish a different principal residence, and a home leased to a tenant may not qualify. Buying a home at your next station generally ends the Texas homestead, so ask the appraisal district about your situation.
