Now we get to the real numbers everyone wants to know. Many taxing entities will adopt the same rate and claim they are not raising taxes. WRONG! Take the tax revenue per penny, multiply by last year's tax rate, multiply by 100, subtract last year's total taxes to find out how much taxes are really going up. For Schertz, the math works out to a $389,589 tax increase. But wait, many taxing entities increase their tax rate by "just a penny or two." In that case, take the tax revenue per penny, multiply it by the PROPOSED tax rate, multiply by 100, then subtract last year's total taxes to determine the actual tax increase. I guarantee that if you attend a public hearing, sign up to speak and reveal these hidden numbers, you will definitely get a reaction.
