'Portability' in Florida refers to the ability of a property owner to transfer some or all of the 'Save Our Homes' benefit on a previous homestead to a newly established homestead. The law was passed as a constitutional amendment in January 2008. The 'Save Our Homes' benefit is the difference between the assessed value and market value of a homestead property due to the annual limit on increases in assessed value.
The amount is either transferred in its entirety or as a percentage depending on the value of the new property. You may not port more than $500,000.
State law allows you to transfer your 'Save Our Homes' benefit to a new home if you had the homestead exemption on your old home in either of the two tax roll years preceding the year for which you established your new homestead. While a property owner may file for portability in later years, the homestead exemption on the new property must be established within two years of abandoning the previous homestead in order to qualify.
Portability forms are available below or by calling the Property Appraiser's Office Customer Service/Exemptions Division at (904) 630-2020. Applications can be mailed to: Property Appraiser's Office, Customer Service/Exemptions Division, 231 E. Forsyth Street, Suite 260, Jacksonville, Florida 32202, and postmarked by March 1. They will also be accepted by email to firstname.lastname@example.org or by fax to (904) 630-2525.
If you already applied for a homestead exemption on your new home, you must complete a separate portability application by March 1 to transfer the 'Save Our Homes' benefit. Or you may file for both by March 1.
Applications filed after March 1st are considered late. Late applications will be accepted through the 25th day following the mailing of the Notices of Proposed Property Taxes in August.
