The Department is aware that some taxpayers using older
Apple/Mac Safari or Chrome browser versions may encounter a
security message when attempting to use the Guest User login
button to File a Return. The message says: “This website may be
impersonating portal.florida.revenue.com to steal your personal
information, you should go back to the previous page.” If you
encounter this message, please ensure you have installed the
latest macOS Tahoe version (version 26.0.1 or later).
