Refining & Petrochemical Property Tax
Process units. Reactors. Complex facilities. Deep cost-approach expertise for your most valuable assets.
Refineries and petrochemical facilities represent some of the highest-value industrial properties in Texas — and correspondingly, some of the largest property tax liabilities. Appraisal districts frequently use simplified cost schedules that fail to account for the true economic condition of aging process units, functional obsolescence in specific product configurations, or external economic pressures facing the industry.
Property Tax Partners has deep experience in refinery and petrochemical property tax. Our consultants understand process unit valuation, the application of Marshall & Swift and other cost guides to complex process equipment, and how to document and defend economic and functional obsolescence claims.
For operators running large industrial facilities, even a modest percentage reduction in assessed value can translate to millions in annual tax savings. PTP delivers the detailed, technically rigorous analysis required to achieve those results.

Common Assessment Challenges
- Complex process facilities require sophisticated cost approach analysis beyond standard schedules
- Economic obsolescence from refinery margin compression is often ignored by appraisal districts
- Functional obsolescence in facilities configured for specific crude slates is rarely recognized
- High capital improvement costs can trigger reassessment that doesn't reflect actual value added
- Environmental compliance investments frequently inflate assessed values without proportional value increase

Frequently Asked Questions
How do appraisal districts value refineries and petrochemical plants?
Most Texas appraisal districts use the cost approach, estimating replacement cost new less depreciation. However, the complexity of process facilities often leads to errors in cost estimation and inadequate depreciation allowances. PTP challenges these valuations using detailed cost analysis, depreciation studies, and obsolescence documentation.
What is "economic obsolescence" for a refinery?
Economic obsolescence reflects losses in value caused by external factors beyond the property itself — such as low refinery margins, regional market conditions, or structural changes in the petroleum industry. When these factors reduce profitability, the income-producing capacity of the facility is diminished, and assessed values should reflect this reality. PTP builds defensible economic obsolescence studies to support reduced assessments.
How long does a refinery property tax protest take?
The informal hearing and ARB process typically concludes within 3-6 months of the initial filing. Complex matters that proceed to district court or binding arbitration can take 1-2 years. PTP manages the entire timeline and keeps you informed throughout.
