That X amount is with the tax base we have now with no increases or new construction. If the tax base goes up, the amount each person is taxed goes down.
I saw an estimate that there were 500 residential lots left to build on in NISD. That doesn’t include any houses that are being torn down or any business. The cheapest houses being built are $200k. $200k x 500 is $100 million more of tax base.
This doesn’t include any value increases from current homes. They can only increase your taxes a small percentage each year if you have a homestead. If you have lived in your home for more than a few years, your taxable value is most likely way below market value. That will stay lower until you sell and then JCAD will adjust it to near market. If you don’t plan on selling anytime soon, then you don’t have to worry about your property value shooting up.
