For commercial property owners across Texas, property tax bills are arriving. And while the amount due may be the first thing that catches your attention, the number worth examining more closely is the valuation behind it.

Your 2026 property tax bill reflects decisions made months ago, based on your property’s assessed value and the tax rates adopted by local taxing authorities. But does that valuation accurately reflect your property’s market conditions, performance, and circumstances?

For owners of commercial real estate, particularly those managing multiple properties, even relatively small valuation discrepancies can have a meaningful financial impact.

The question isn’t simply how much you owe. It’s whether you’re being taxed on an accurate value — and what options may still be available.

1. Understand What’s Driving Your Property Tax Bill

Before paying your bill, it’s worth understanding how the amount was calculated.

In Texas, property taxes are based on a property’s taxable value and the rates established by local taxing entities, including counties, cities, school districts, and special districts.

Your property’s valuation is established by the local appraisal district, generally based on its value as of January 1 of the tax year.

That distinction matters.

The valuation used to calculate your 2026 tax bill reflects a specific point in time, which may not align with your property’s current financial performance or market conditions.

For commercial property owners, several factors can influence whether a valuation is reasonable:

• Occupancy and vacancy: Were vacancy rates, lease-up challenges, or tenant departures adequately reflected?

• Rental income: Does the valuation reflect achievable market rents and actual property performance?

• Operating expenses: Were rising insurance, maintenance, property management, and other operating costs appropriately considered?

• Capital expenditures: Does the property require significant repairs, improvements, or deferred maintenance?

• Market conditions: Have comparable property values, capitalization rates, or investor expectations shifted?

• Property characteristics: Are the square footage, building condition, use, and other property details accurately recorded?

These factors don’t automatically mean your property has been overvalued. But they may warrant a closer examination of the appraisal district’s assumptions.

2. Review Your Assessed Value — Not Just the Amount Due

A higher tax bill doesn’t necessarily mean your property was overvalued. Changes in local tax rates, exemptions, and taxable values can all affect the final amount.

That’s why reviewing the bill alone isn’t enough.

Start by comparing your 2026 assessed and taxable values against prior years. Look for significant changes and consider whether they are supported by the property’s actual circumstances.

For example, a commercial office building experiencing increased vacancy or declining rental income may warrant a different valuation analysis than a fully occupied property with stable cash flow.

Similarly, an industrial property with aging improvements or significant deferred maintenance may have characteristics that aren’t fully reflected in a mass appraisal model.

For owners with large portfolios, these discrepancies can become especially important. A valuation issue affecting one property may be manageable. Similar issues across ten, twenty, or fifty properties can create a much larger financial exposure.

A portfolio-wide review can help identify patterns, prioritize opportunities, and establish a more proactive approach to managing property tax expenses.

3. Missed the Protest Deadline? Understand Your Remaining Options.

For most Texas property owners, the regular deadline to protest a 2026 appraisal was May 15 or 30 days after the appraisal district delivered the notice of appraised value, whichever was later.

By November, that regular protest window has generally closed.

However, that doesn’t necessarily mean every available option has expired.

Depending on the circumstances, property owners may still have certain remedies.

If you already protested your valuation

Owners who participated in an Appraisal Review Board (ARB) hearing and disagree with the final determination may have additional appeal options.

For example, an appeal to district court generally must be filed within 60 days after receiving the ARB’s written order. Other appeal mechanisms, including binding arbitration or review through the State Office of Administrative Hearings, may be available for qualifying properties and disputes.

These deadlines are tied to the ARB’s order, not the arrival of the property tax bill.

If you didn’t protest earlier this year

Certain late-protest or appraisal-roll correction procedures may be available under specific circumstances, including qualifying errors in appraisal records or required notices.

However, these remedies have strict eligibility requirements and deadlines. They are not a general opportunity to reopen an appraisal simply because the tax bill is higher than expected.

The important next step is determining whether your property qualifies for an available remedy rather than assuming all options are closed.

4. Don’t Overlook Your Property Tax Payment Deadline

Even if you’re questioning your valuation or pursuing an appeal, it’s important to understand your payment obligations.

For most Texas property owners, 2026 property taxes must be paid by January 31, 2027, to avoid delinquency, subject to applicable deadline rules and exceptions.

Unpaid taxes generally become delinquent on February 1, with penalties and interest beginning to accrue.

Property owners pursuing certain appeals are also typically required to pay at least the undisputed portion of their taxes before the delinquency date, subject to applicable legal requirements.

An ongoing valuation dispute does not automatically suspend your payment obligations.

For commercial property owners, particularly those with multiple properties or substantial annual tax liabilities, coordinating payment requirements with any remaining appeal options is an important part of managing risk.

5. Use This Year’s Tax Bill to Prepare for 2027

Even when the opportunity to challenge a 2026 valuation has passed, reviewing your current tax bill can provide valuable insight for the next assessment cycle.

Property tax management shouldn’t begin when the appraisal notice arrives in the spring.

By that point, important opportunities to document your property’s condition, financial performance, and market circumstances may already have been missed.

The months ahead are an opportunity to take a more proactive approach.

Consider gathering and reviewing:

• Current rent rolls, lease terms, and occupancy information

• Property-level income and operating expense statements

• Documentation of deferred maintenance and capital improvements

• Recent appraisals, sales, and relevant market comparables

• Prior-year assessments, protests, and ARB determinations

• Property records and business personal property information, where applicable

For 2027, Texas commercial property valuations will generally be based on conditions as of January 1, 2027.

Having accurate, well-organized information available before the next appraisal cycle can help establish a stronger foundation for evaluating and, when appropriate, challenging future assessments.

6. For Portfolio Owners, the Opportunity May Be Bigger Than One Tax Bill

For owners of multiple commercial properties, tax exposure extends well beyond an individual assessment.

Different counties, appraisal methodologies, property types, and market conditions can create inconsistencies across a portfolio.

A coordinated review can help identify which properties warrant additional attention and where potential tax savings may be most meaningful.

It can also help owners establish a more consistent process for tracking assessments, deadlines, supporting documentation, and protest outcomes.

Rather than evaluating each property independently when a tax bill arrives, a portfolio-level strategy allows owners to approach property taxes as an ongoing operating expense that deserves active management.

The goal isn’t simply to reduce one year’s tax bill. It’s to ensure your properties are being valued fairly and consistently over time.
