This has nothing to do with your income tax return. It is not a credit, it is an exemption and you obtain it locally.
In the state of Florida, a $25,000 exemption is applied to the first $50,000 of your property's assessed value if your property is your permanent residence and you owned the property on January 1 of the tax year. This exemption applies to all taxes, including school district taxes.
