The 2021 reform removed the old requirement for a local Emirati partner holding a majority stake in mainland companies, which is why mainland now genuinely competes with free zones for foreign owners rather than being the fallback only sponsors could access. What survives from before is the market-access split: a free zone entity is licensed to operate inside its own zone and abroad, not across the wider UAE market directly.
The practical difference shows up later than people expect, at the point of hiring or leasing. A free zone company that later needs a mainland presence, say to hold a government tender or lease retail space outside its zone, generally has to set up a second licensed entity rather than convert the existing one. Deciding based on where your actual customers sit up front avoids running two structures in parallel.
