Under Florida law, you can apply to get off the sex offender registry after 25 years. This length of time begins once your sentence has ended, including jail time, probation, or parole requirements. Once 25 years from the completion of these requirements has elapsed, you are eligible, provided you have not committed any further felonies or misdemeanors since your release, the original offense was not severe, and you are registered as a sex offender and not a sexual predator.
