The appraisal districts job is finished for the current year. It has provided a set of equal and uniform values for all local taxing units to use. Now the taxing units decide what services they will provide in the coming year and how much money they will need. Each taxing unit adopts a tax rate that will raise the needed tax dollars. As a taxpayer, its important for you to understand how government spending, property values, and tax rates affect the size of your own tax bill.
Property values determine each taxpayers share of the total taxes.
Changes in property values may affect the tax bills of individual owners, but they do not necessarily increase or decrease the total amount of taxes to a taxing unit. A taxing unit's budget determines the total amount of taxes. A change in the tax rate by itself does not reflect an increase or decrease in taxes. Total taxes increase only when government spending increases. The only meaningful way to compare tax rates is to compare the amount of tax revenue they produce.
