Western Refining, El Paso's largest property taxpayer, recently settled a three-year fight over the taxable value of its El Paso refinery, and cut its mammoth tax bill by $5.7 million as a result.

Western is the biggest example of what is a perpetual battle between commercial property owners and the El Paso Central Appraisal District over property valuations set by the district. Those values determine how much tax the property owners will pay.
