This post might help someone who purchased a property in 2022.
All legal Florida residents are eligible for a Homestead Exemption on their homes, condominiums, co-op apartments and certain mobile home lots. The exemption removes $25,000 off the assessed value of an owner-occupied residence and could provide up to another $25,000 additional exemption off assessed value over $50,000. (This additional exemption does not apply to school millage.) Not only does the homestead exemption lower the value on which you pay taxes, it also triggers the 'Save Our Homes' benefit, which limits future annual increases in assessed value to 3% or less. The sale of the property, changes in ownership or changes to the property can cause the exemption and benefit to be removed or altered. (When a home is sold, the assessed value increases to market value for the next tax roll.)
You are entitled to a Homestead Exemption if, as of January 1, you have made the property your permanent home or the permanent home of a person who is legally or naturally dependent on you. To be eligible for a homestead exemption, you must own and occupy your home as your permanent residence on January 1. The deadline to timely file for a homestead exemption is March 1, 2023.
