Bexar County Commercial Property Tax Protest

Something changed in Bexar County that every commercial property owner should know about. Starting in 2025, any property owner who successfully protests their valuation won’t see their market value increase the following year — unless they’ve made actual improvements to the property. That’s a significant policy shift from BCAD, and it makes protesting your 2026 value even more strategically important.

Bexar County isn’t a small market, either. With a total property value exceeding $308 billion and an estimated $4.87 billion in annual property tax collections, this is a county where even modest overassessments add up to real money fast. Over 60,000 commercial and business personal property protests were filed with BCAD last year — a clear signal that the district is systematically overvaluing commercial assets.

For commercial property owners across San Antonio and Bexar County, the 2026 appraisal cycle presents both a challenge and an opportunity. BCAD’s reappraisal methodology has become increasingly aggressive, particularly in fast-growing areas like the Stone Oak corridor, The Rim, and Port San Antonio. At the same time, Bexar’s tax environment is more favorable than neighboring counties, and the new valuation freeze policy makes protesting a smarter investment than ever before.

This guide compares Bexar County’s assessment patterns to neighboring markets, identifies overassessment hot spots, and shows you exactly how to protect your commercial investment.

How Bexar County Compares to Neighboring Counties

Understanding where Bexar stands relative to neighboring counties reveals why commercial owners here need to act. Bexar County sits at the center of South Texas, surrounded by Comal, Guadalupe, Medina, and Kendall counties. Each has its own appraisal district, different reappraisal cycles, and distinct assessment philosophies.

Comal County (north of San Antonio). With a much smaller tax base than Bexar and slower commercial growth, Comal County’s effective tax rates on commercial property run 2.3% to 2.5%. CCAD (Comal Central Appraisal District) uses more conservative cap rates (8.0% to 10.0% for income-producing properties) than Bexar, meaning commercial properties here are valued lower relative to income. This is partly because Comal’s market hasn’t experienced the speculative development pressure that Bexar has seen along the 281 corridor and far North Side.

Guadalupe County (east/northeast). Guadalupe County’s commercial markets in Seguin and Schertz are growing, but still less mature than San Antonio proper. GCAD’s effective commercial tax rates sit around 2.2% to 2.4%. Notably, Guadalupe reappraises on a different schedule than Bexar (odd-numbered years), which creates a timing advantage for owners of cross-county properties.

Medina County (southwest). More rural than Bexar, Medina County has lower commercial property values overall. MCAD’s effective rates average 2.0% to 2.2% on commercial property. Few major commercial centers exist outside Hondo and smaller communities, so MCAD’s appraisers have less experience with the income approach and sophisticated valuation methods — meaning less aggressive overassessment, but also sometimes inconsistent valuations.

Kendall County (north). Among the fastest-growing counties in Texas, Kendall has seen explosive residential and commercial development around Johnson City and Boerne. KCAD’s effective commercial tax rates are actually lower than Bexar’s (2.0% to 2.3%), despite rapid growth. This is because Kendall’s appraisal district has been more transparent about cap rates and uses market data more conservatively.

Bexar County’s position. Bexar sits at 2.1% to 2.8% combined effective rate depending on location within the county. Downtown San Antonio and the South Texas Medical Center push toward the higher end. The critical difference: Bexar County’s cap rates are too aggressive. BCAD uses 6.5% to 8.5% cap rates for many commercial properties, while neighboring markets use 8.0% to 10.0%. Lower cap rates inflate value dramatically. A property generating $100,000 in annual NOI:

• At 7.0% cap rate = $1.43 million value
• At 8.5% cap rate = $1.18 million value
• Difference = $250,000 overassessment

That’s the Bexar County problem in a nutshell.

The Bexar County Commercial Market and Its Hot Spots

San Antonio’s economy has undergone transformation over the past five years. Downtown and tourism-driven properties perform differently than far North Side industrial. Understanding these submarkets reveals where overassessment is most acute.

Downtown San Antonio and the River Walk corridor. The heart of San Antonio’s commercial district stretches from the Alamo to the Pearl District and beyond. Hotels, restaurants, retail, and office properties pack this area. Post-pandemic travel recovery has been strong, but BCAD’s hotel valuations sometimes reflect 2019 peak occupancy rather than current market conditions. Average occupancy across San Antonio hotels is now 68% to 72%, down from pre-2020 levels of 75%+. If your hotel is valued assuming 75% occupancy but runs at 70%, you’re paying taxes on phantom income.

Medical office and the South Texas Medical Center. UT Health, Christus, Methodist, and other major health systems anchor this area. Medical office rents in the core Medical Center run $25 to $35 per square foot annually. Secondary medical office properties in Balcones Heights, Leon Valley, and Alamo Heights run $18 to $24 per square foot. BCAD frequently applies core Medical Center rents to secondary properties, inflating their values by 10% to 25%. This is one of the highest-opportunity protest categories in Bexar County.

Brooks Development. The former Brooks Air Force Base has transformed into mixed-use commercial, industrial, and office space. Development is still ramping up, but BCAD has been aggressive with “as-if-stabilized” valuations on incomplete projects. Speculative valuation on stabilizing properties is a classic overassessment pattern. If your property is valued at stabilized occupancy but hasn’t reached it, you have strong protest grounds.

Port San Antonio and the I-10 East industrial corridor. Port San Antonio’s redevelopment has driven substantial industrial and logistics property development. This area is booming, and warehouse rents have climbed. However, BCAD has been slow to differentiate between premium warehouse (near port, good rail access, clear heights) and secondary warehouse further east. A newer, 40-foot-clear warehouse gets the same per-square-foot valuation as a 20-foot-clear building built in 1985. That’s systematic overassessment of older properties.

Stone Oak and North San Antonio growth corridor. The Stone Oak area along Loop 1604 has exploded commercially over the past decade. Retail, medical office, and mixed-use developments have fundamentally changed the tax base here. Because growth has been so rapid, BCAD’s comps database is often outdated — using 2021 and 2022 sales data when 2024 and 2025 sales show slower price growth. On a new retail center, this can mean a 5% to 10% overassessment.

La Cantera and The Rim shopping districts. These are high-performing retail and mixed-use centers. Rents are strong ($35 to $50+ psf), but both properties are mature and not experiencing appreciation. BCAD’s valuations sometimes assume continued rent growth that isn’t materializing. A retail property valued assuming 3% annual rent increases that actually sees 1% or no increases is overassessed.

I-35 corridor and the JBSA proximity premium. The I-35 corridor from Schertz through live Oak and into northeast San Antonio commands a proximity premium due to Joint Base San Antonio activity. Office and light industrial properties near the base see higher occupancy and stronger rents than similar properties elsewhere. However, BCAD sometimes applies a JBSA premium to properties that aren’t actually in the JBSA trade area. If your property is technically near I-35 but has no JBSA tenants, you may be paying for a premium you’re not getting.

Loop 1604 business parks. Along the entire Loop 1604 corridor, newer office and flex space has attracted growing companies. BCAD tends to value all Loop 1604 office at premium rates, even older buildings competing with newer product. A 15-year-old office building on Loop 1604 shouldn’t be valued the same as a brand-new LEED building with identical rents — the newer building commands premium rents, but the older one shouldn’t.

BCAD’s Overassessment Patterns: The Income Approach Problem

The Bexar Central Appraisal District primarily uses three approaches to value commercial property: the sales comparison approach, the income approach, and the cost approach. For most income-producing commercial property, the income approach dominates — and that’s where overassessment happens most often.

BCAD’s income approach works like this:

1. Estimate the property’s annual Net Operating Income (NOI)
2. Select a capitalization (“cap”) rate
3. Divide NOI by cap rate to get value: Value = NOI / Cap Rate

The problem: BCAD’s cap rate selection is too aggressive (too low). Using a 6.5% cap rate inflates values compared to using a 7.5% or 8.5% cap rate. And BCAD’s NOI estimates often fail to account for:

• Actual vacancy. If a property has 15% vacancy but BCAD assumes 5%, NOI is overstated by 10%. On a $1 million revenue property, that’s $100,000 in phantom NOI — about $1.4 million in inflated value at a 7% cap rate.

• Tenant mix and credit quality. BCAD might assume all tenants are investment-grade when you’ve got 20% of income from marginal tenants. This risks future vacancy and lease-up issues.

• Capital expenditure reserves. BCAD should subtract 5% to 10% from gross income for CapEx reserves (roof replacement, HVAC, parking lot reseal). They often don’t, or they underestimate reserves.

• Management and leasing costs. BCAD might use a 4% management fee while your actual cost is 6% or 7%. Every 1% difference in operating expense assumptions changes value by roughly 1.4% at a 7% cap.

• Market rent growth expectations. BCAD sometimes assumes annual rent growth of 2% to 3% even in flat or declining markets. In 2025, San Antonio saw little rent growth; yet properties were still valued assuming continued appreciation.

The specific Bexar overassessment signatures:

1. Cap rates of 6.5% to 7.0%. Bexar’s commercial cap rates are lower than comparable Texas markets (Dallas: 7.0%–8.5%, Houston: 6.8%–8.0%, Austin: 6.0%–7.5%). The fact that Bexar’s overall cap rates fall at or below Austin’s is suspicious, given San Antonio’s smaller, less liquid market. A property that would cap at 8.0% in Houston is capped at 6.8% in Bexar. That’s roughly $300,000 in extra value per $1 million in NOI.

2. Stabilized assumptions on non-stabilized properties. New retail, office, and mixed-use in developing areas are valued as if they’ve achieved full occupancy and market rents immediately. In reality, lease-up takes 2 to 3 years. Valuing a 60%-leased property as if it’s 90%-leased is a formula for overassessment.

3. Failure to adjust for tenant quality and lease terms. Short-term leases, struggling tenants, and below-market renewals don’t always reduce BCAD valuations proportionally.

Tax Rates, Cap Rates, and What You’re Actually Paying

Let’s be concrete about what Bexar County commercial property taxes actually cost:

Data Point	Value
Total market value (2023)	$308.29 billion
Total property tax collections	$4.87 billion
County tax rate	$0.2668 per $100 valuation
City of San Antonio tax rate (city limits)	$0.5476 per $100 valuation
Northside ISD tax rate	$1.0122 per $100 valuation
Judson ISD tax rate	$1.0389 per $100 valuation
North East ISD tax rate	$0.9889 per $100 valuation
San Antonio College District tax rate	$0.0794 per $100 valuation
Effective combined rate (typical)	2.1% to 2.8%
BCAD cap rate range (income approach)	6.5% to 8.5%
Market cap rate range (comparables)	7.5% to 9.5%
Average commercial property assessment	$2.0M to $5.0M
Average annual property tax bill	$42,000 to $140,000

On a $3 million commercial property in San Antonio city limits:

• Annual property tax = $3,000,000 × 2.5% = $75,000

If BCAD is overestimating value by 15% (a conservative estimate given cap rate analysis):

• Overstated value = $450,000
• Annual tax overpayment = $11,250
• Over 10 years = $112,500

And that’s without considering the benefit of the new reappraisal freeze. When you win a protest, the property’s value freezes the next year (absent improvements), compounding your savings.

Why BCAD’s New Reappraisal Policy Changes Everything

In 2025, BCAD implemented a significant policy change. After a property successfully protests its appraised value, that property’s market value won’t automatically increase in subsequent years (even if the market rises) unless actual capital improvements are made. This is a major departure from standard Texas appraisal practice.

What this means: If you protest and win a $3 million to $2.8 million reduction in 2026, your value stays at $2.8 million through 2027 even if comparable properties appreciate. You lock in a lower tax base.

Under the old system, winning a protest saved you money in Year 1, but the CAD would reappraise you upward in Year 2 based on the market, partially erasing your gain. Now, the freeze period extends your savings for multiple years.

The math on a 10-year hold:

• Overassessed value today: $3.0M
• Fair market value: $2.7M
• Annual overassessment: $225,000 in value × 2.5% tax rate = $5,625/year

Without protest freeze:

• Year 1–2 savings: $5,625 × 2 = $11,250
• Years 3–10: Property reappraises upward, savings diminish

With protest freeze:

• Year 1 savings: $5,625
• Years 2–3 savings: $5,625 (frozen value, no increase)
• Years 4+ savings depend on actual improvements; if none, freeze continues

You’re potentially saving $45,000 to $50,000 over a decade on a single $3 million property. That’s why filing now is so important.

How Bexar County Commercial Protests Work

The protest process with BCAD is governed by Texas Tax Code § 41.41. Here’s the step-by-step:

Step 1: Receive your BCAD Notice of Appraised Value. BCAD mails these in late March or April. The notice shows your property’s appraised value and the effective tax rate.

Step 2: File your Notice of Protest. You have 30 days after BCAD mails the notice or until May 15, 2026, whichever is later. File online at bcad.org, by mail to BCAD (PO Box 1906, San Antonio, TX 78297), or in person at their office. Include a brief statement of why you believe the value is excessive.

Step 3: Attend the informal hearing. BCAD schedules an informal conference (usually 2–3 weeks after you file). This is where you meet with a BCAD appraiser, present comparable sales, income data, and property condition information, and make your case. Many protests are resolved here without further proceedings. The appraiser can reduce the value on the spot or schedule a formal hearing.

Step 4: Formal ARB hearing (if needed). If the informal hearing doesn’t produce a fair result, your case goes to BCAD’s Appraisal Review Board (ARB). The ARB is composed of property owners and business people, not appraisers. You present evidence (comps, income statements, expert reports) and the appraisal district presents its position. The ARB votes on whether the appraised value should be reduced.

Step 5: District court appeal (if needed). If the ARB rules against you, you can appeal to Bexar County District Court. Court appeals are expensive and usually involve hiring a real estate appraiser expert, so they’re pursued only on high-value properties.

BCAD contact information:

• Main office: (210) 242-2000
• Taxpayer Liaison: (210) 242-2432
• Website: https://bcad.org
• Address: 1900 W Woodlawn Ave, San Antonio, TX 78228

Bexar County’s informal hearing process tends to be collaborative. The appraisers at BCAD are experienced and willing to negotiate if you bring current market data. They see 60,000+ protests a year, so they know which properties get overvalued. Your job is to document it.

Property Types We Commonly Protest in Bexar County

Each commercial property type in Bexar County has characteristic overassessment patterns. Understanding yours helps you build a stronger protest:

Retail centers and shopping districts. Bexar has dozens of neighborhood retail, community centers, and power centers. BCAD tends to value all retail the same per square foot, even though different properties have very different risk profiles. A 40-year-old center with 85% occupancy and one large anchor shouldn’t be valued the same as a brand-new center with investment-grade tenants at 95% occupancy. We see 5% to 15% overassessment in older retail.

Medical office. Medical office is booming in San Antonio, but secondary medical office (Balcones Heights, Alamo Heights, outside the core Medical Center) is valued at core Medical Center rates. We see 8% to 18% overassessment when secondary properties are compared to their true market. The difference between $32 psf (core) and $22 psf (secondary) is substantial on a 20,000 square foot building.

Industrial and warehouse. Port San Antonio and I-10 East warehouses are prime examples. BCAD values a 20-year-old warehouse with 20-foot clear height the same as a brand-new 40-foot-clear facility nearby. This creates systematic overassessment of older buildings. We target properties where construction vintage creates a 10%+ value gap.

Office. Downtown San Antonio office is stable but experiencing slow migration to newer suburban product (Loop 1604, Stone Oak). Older buildings with higher vacancy should be worth less, but BCAD sometimes uses market-wide vacancy rates rather than property-specific rates. A downtown office building at 75% occupancy that the CAD values at 88% occupancy is overassessed.

Hotels and hospitality. San Antonio’s tourism recovery is real but uneven. Downtown and River Walk hotels perform well (70%+ occupancy). Suburban hotels and select-service properties near the airport or JBSA run 60% to 68% occupancy. BCAD’s valuations sometimes blend occupancy rates, assigning downtown performance to suburban properties. Overassessment of 8% to 12% is common.

Mixed-use and development properties. Brooks, Port San Antonio, and far North Side mixed-use projects are valued at “stabilized” rates long before they stabilize. BCAD assumes 95%+ occupancy on a project that’s still 70% leased. We see 10% to 25% overassessment on non-stabilized projects.

What Successful Bexar County Protests Look Like

Winning a protest requires evidence. Here’s what an effective protest package includes:

1. Comparable sales. Current sales of similar properties in Bexar County or immediately adjacent counties (Comal, Guadalupe). BCAD sales from 2024 and 2025 are most relevant. We want at least 3 to 5 solid comps showing that similar properties sold for less than the appraised value.

2. Income analysis. If the property generates income (retail, office, hotel, industrial), we obtain the owner’s actual operating statements, lease summaries, and tenant roster. We calculate the property’s true NOI and apply market-appropriate cap rates to derive a value. When our income analysis shows 15% lower value than BCAD’s, that’s a protest winner.

3. Property condition assessment. Photos, inspection reports, capital expenditure lists. If the property needs roof replacement, HVAC work, parking lot reseal, or tenant improvements, those are capital costs that reduce value. BCAD often underestimates deferred maintenance.

4. Appraisal report or expert analysis. For properties over $1.5 million or technically complex cases, a third-party appraisal by a Texas-licensed appraiser carries substantial weight at an ARB hearing. The appraiser documents overestimation of cap rate assumptions, vacancy assumptions, or comp selection.

5. Market data and trends. Brokerage reports, CoStar data, or commercial real estate market summaries showing recent market conditions. If the Bexar County market has slowed rent growth or occupancy is down, that evidence supports lower value.

With 60,000+ protests filed annually in Bexar County and strong evidence, property owners frequently achieve success at informal hearing. Those with well-documented cases can pursue further review if needed. BCAD’s appraisers recognize the most common overassessment patterns.

The Financial Case: What a Successful Protest Saves You

Let’s walk through a realistic example:

Scenario: 25,000 sq ft retail center, South San Antonio

• BCAD appraised value: $3.5 million
• Your estimate of fair market value: $3.0 million (comps, rental analysis support this)
• Overassessment: $500,000

Annual tax calculation:

• County tax: $500,000 × $0.2668 / 100 = $1,334
• City of San Antonio tax: $500,000 × $0.5476 / 100 = $2,738
• ISD tax: $500,000 × $1.0122 / 100 = $5,061
• Total annual overpayment: $9,133

Our fee: 30% of first-year savings = $2,740 (paid only if we win and you pay less)

Your net savings, Year 1: $9,133 - $2,740 = $6,393

Your savings, Years 2-5 (with reappraisal freeze, assuming no property improvements): $9,133 × 4 = $36,532

Your total 5-year savings: $42,925

On a $5 million property with $750,000 overassessment, first-year annual savings are $13,650. Your five-year savings approach $65,000 to $75,000 even after our fee.

Those numbers are why we can work on contingency. The math works because overassessment is systematic and our success rate is high.

How to Get Started: Your Next Steps

If you own commercial property in Bexar County and your 2026 BCAD notice shows an increase, protesting is almost always worth your time.

Here’s the process:

1. Gather your property information. Get your BCAD notice, recent operating statements (if income-producing), photos, and any lease documentation.

2. Request a free assessment. Send us your property details. We’ll pull BCAD’s data, run a comparable analysis, and send you a preliminary opinion within 48 hours. This is completely free and non-obligatory.

3. Review our findings. We’ll tell you whether we think your property is overassessed, by how much, and what protest strategy we recommend.

4. Authorize us to file. If you approve, we handle the Notice of Protest filing, all evidence gathering, and representations at both informal and formal hearings (if needed).

5. Receive your reduction. Once BCAD (or the ARB) reduces your value, we calculate savings, take our 30% fee from Year 1 only, and you keep the rest.

Your deadline is May 15, 2026. Don’t miss it. Once that date passes, you forfeit your right to protest the 2026 value.
