This exemption helps the homeowner to save money on their property taxes by removing a portion of the assessed value of the primary property for your taxes so that you don’t have to pay the taxes according to the market value.
For example, if the market value of your property is $250,000 and the county assessed value is $180,000, you are liable to pay the property tax on $180,000 and not the $250,000.
Most of the time the county assessed value is going to be lower than the current market value of the property.
In the state of Texas, a homeowner can get a homestead exemption for up to $25,000 of the assessed property value which has to be your primary residence. This tax exemption is only for your primary residence.
You cannot file for the exemption on your rental home or secondary home.
