Florida businesses typically need licenses at three levels: local (city/county business tax receipt), state (professional or industry-specific licenses through DBPR or other agencies), and sometimes federal (liquor wholesale, firearms dealers, aviation). Most businesses need all three layers — start local, work up to state, and investigate federal only for regulated industries. Contact your city's business development office first; they often provide a licensing checklist specific to your business type.
Florida's Division of Corporations website (Sunbiz.org) and the My Florida Business portal (myfloridabusiness.com) allow you to register your business, search for required licenses, and manage annual filings in one place. The state's "Business Wizard" tool at myfloridabusiness.com walks you through questions about your business type and location to generate a customized checklist of required licenses and registrations. Use this tool before any other resource.
The Florida Department of Business and Professional Regulation (DBPR) issues licenses for over 200 professions. You can search existing licenses, verify a contractor or professional's credentials, and apply for new licenses at myfloridalicense.com. Many Florida consumers verify license status before hiring contractors — maintaining an active, violation-free license is a competitive advantage and marketing asset.
Operating without required licenses in Florida can result in criminal charges (second-degree misdemeanor for unlicensed contracting, a felony for repeat offenses), civil fines up to $10,000 per violation per day, forced business closure, and inability to collect payment for work already done. Courts have ruled that unlicensed contractors cannot enforce contracts — meaning you could perform $50,000 in work and have no legal recourse to collect.
