Children under 16 years old and adults older than 65 don't need a fishing license, according to the Florida Fish and Wildlife Conservation Commission. These license exemptions apply to both saltwater and freshwater fishing licenses.
Kids who are under 16 and their parents should be prepared to show proof of age if fishing without a license. Adults who are 65 or older should be prepared to show proof of both age and residency. County tax collector offices provide complimentary fishing permits to eligible seniors, according to the Florida Fish and Wildlife Conservation Commission. Both kids and seniors can purchase optional fishing licenses from tax collector offices or local retail stores. Funds from these licenses support Florida conservation efforts.
