There are two reasons for your property taxes to increase: (1) a tax rate (millage) increase, or (2) an increase in the appraised value of the property. The first reason, a tax rate increase, would have to come from a vote of the citizens or by the taxing authority (County Commission) to increase (or decrease) the millage rate. The second situation, involving an increase in the appraised value, would come from a court ordered re-appraisal or from an “economically-based” increase in the market value of properties in the county, resulting in an increase in the appraised value.
