How to Lower Your Property Tax Bill in Martin County
If you own and live in your home in Martin County, you can apply for a homestead exemption to reduce your taxable property value.
A homestead exemption cuts the taxable value of your home. School districts in Texas must give you a $140,000 exemption on your main home. That means your school taxes are based on a lower number. Some local taxing units may offer extra exemptions on top of that.
You apply with the Martin County Appraisal District, not the tax office. The general deadline is before May 1. You will need to show proof of your address, like a Texas driver's license. You can only claim this on one home. Check the appraisal district website or call for current forms and deadlines, since rules can change.
