Identify the temporary limit that actually applies
An owner of Texas operating premises may see an appraised value below the latest market estimate and assume that the same growth limit will continue indefinitely. The current non-homestead circuit breaker requires a separate review. Its eligibility, ownership timing, treatment of improvements, and stated expiration differ from a residence homestead limitation.
The Texas Comptroller’s current guidance describes a limit for qualifying real property other than a residence homestead. For 2026 it identifies a $5,320,000 eligibility amount and states that the limitation expires December 31, 2026. The calculation generally compares market value with the prior appraised value plus 20% and qualifying new improvements. It does not establish a 20% ceiling on the dollar tax bill.
Confirm the premises’ eligibility and the applicable ownership history with the appraisal records. A business using a building does not prove that its legal owner has met the timing requirements. Separate the land and improvements account from the operating business’s personal property account so a rule for one does not silently control the other.
Calculate the current value limit before projecting tax
Consider hypothetical eligible premises with a prior appraised value of $1,000,000, current market value of $1,400,000, and $100,000 of qualifying new improvements. The prior value plus 20% plus the assumed new improvements is $1,300,000. Comparing that with $1,400,000 market value produces a $1,300,000 limited value under this simplified scenario.
Without those new improvements, the comparison amount would be $1,200,000. The $100,000 construction component therefore matters even though the owner may describe the whole project as a renovation. The Comptroller distinguishes new improvements increasing value from ordinary repair and maintenance. Have the preparer apply the actual definitions to the construction facts; invoice wording alone does not decide the classification.
At an illustrative combined rate of 2%, $1,300,000 corresponds to $26,000 and $1,400,000 to $28,000 before exemptions, other adjustments, and actual taxing-unit rates. The $2,000 difference is a sensitivity, not a bill estimate. Rates and other assessment factors can change, so a value limitation should not be presented as a guaranteed limit on annual tax growth.
Prepare the post-expiration occupancy budget
Use the published expiration as an explicit planning assumption for 2027 unless a verified law applicable to the property changes the result. Do not simply extend the prior spreadsheet formula because the owner received the limit in 2026. Build a scenario using the supported market-value projection and current understanding of the rules, then refresh it when the relevant assessment information becomes available.
Suppose the business’s draft budget carries the prior illustrative $26,000 amount into 2027. If a supported alternative value and rate scenario produces $30,000, the additional annual reserve is $4,000, or about $333 per month. That planning reserve is not a statement of the future tax rate. It makes the possible end of the limitation visible in rent, debt coverage, and operating cash decisions.
If the premises are held by a related entity and leased to the operating business, review how the lease allocates property tax changes. The building owner’s assessment issue can affect the operating company’s occupancy expense at a different time or through a reimbursement clause. Keep both entities’ cash forecasts aligned with the actual lease terms.
Retain eligibility and improvement support
Keep prior and current appraisal notices, ownership dates, eligibility analysis, construction descriptions, permit records, project invoices, and the calculation supporting the limitation. Identify which improvements were included and why. The file should explain the value calculation independently of the business’s income-tax depreciation treatment.
Review the appraisal notice promptly through the applicable protest or correction procedures if the property’s treatment appears inconsistent with the facts. Do not confuse a disagreement about market value with a disagreement about eligibility or the new-improvement component. Give the adviser each issue separately so it can be addressed through the proper process.
The published rules include special appraisal exclusions, ownership timing, and casualty replacement provisions beyond this example. Current law and the actual account facts govern. This guide does not determine eligibility or predict a 2027 assessment. Its useful owner action is to calculate the 2026 limit correctly, distinguish it from the tax bill, and remove an unsupported assumption of permanent protection from the premises’ future carrying-cost budget.
