Any taxing unit, including a school district, city, county, or special district, may offer an exemption for up to 20 percent of your home's value. The amount of an optional exemption can't be less than $5,000, no matter what the percentage is. For example, if your home is valued at $20,000 and your city offers a 20-percent exemption, your exemption is $5,000, even though 20 percent of $20,000 is just $4,000.
Each taxing unit decides whether it will offer the exemption and at what percentage. This percentage exemption is added to any other home exemption for which you qualify. The taxing unit must decide before July 1 of the tax year to offer this exemption.
