Amarillo City Council members have set the property tax rate, and the result means homeowners will be paying more. While the city’s property tax rate will not change from its current figure, an average 3.55 percent increase in home values will cause some homeowner’s bill to increase, and generate more revenue for the city. In the past decade, Amarillo’s property values have increased 28.3 percent, according to data provided by the Potter-Randall Appraisal District.
