The cleanest way to frame the choice is to ignore the headline tax rates for a minute. Both structures pay 9% UAE Corporate Tax on profits above AED 375,000. The Free Zone 0% rate is conditional, not automatic. Mainland and Free Zone differ on customer access, activity scope, banking, and the documents you have to produce at year end. Pick by those, not by a rate card.
What each actually permits
Mainland (DED-licensed)
A Mainland LLC can invoice any customer in the UAE, sell to UAE government bodies, sign physical leases anywhere in the country, and trade goods across all seven emirates without an extra distributor. Foreign ownership is allowed at 100% for most activities since 2021. The downside is that office rent, Ejari, and Department of Economic Development fees push the year-one cost higher than a Free Zone setup.
Free Zone
A Free Zone entity is licensed by its zone authority (DMCC, IFZA, RAKEZ, Meydan, AFZ, Shams, and others), not the DED. The zone defines the permitted activities. You invoice anywhere in the world. You invoice other Free Zone entities. You invoice Mainland UAE customers, but for taxable supplies the VAT treatment depends on whether the zone is a "Designated Zone" for VAT purposes (most are not). And a Free Zone entity cannot bid on UAE government tenders directly.
The 9% / 0% question is mostly activity-driven
The 0% Free Zone rate is the Qualifying Free Zone Person (QFZP) regime. To qualify, the entity must earn "Qualifying Income" from a defined list of activities, maintain adequate substance in the zone, meet the de minimis test on non-qualifying revenue (lower of 5% or AED 5 million), apply transfer pricing arm's-length on related-party flows, and prepare audited accounts. Fail any condition and the entity is taxed at 9% on all profits above AED 375,000, not just on the bad slice.
The list of Qualifying Activities is narrower than most founders think. Manufacturing, distribution to/from other Free Zones, holding shares and securities, ship/aircraft activities, treasury for related parties, regulated fund management, headquarter services, logistics, and reinsurance qualify. Consultancy services to a Mainland UAE customer do not qualify. Marketing services to the UAE market do not qualify. That is why a Dubai-based marketing consultancy in DMCC often pays 9% in practice.
If your customers are mostly outside the UAE, Free Zone wins almost every time. If your customers are mostly inside the UAE, the answer depends on the activity list and the de minimis test. We see founders in Free Zones paying 9% who could have planned around it.
The boring practicals
Banking
UAE banks are equally comfortable with both. The bigger driver is the activity description, beneficial ownership, and source of funds. Mainland LLCs sometimes find regional banks slightly faster (Mashreq, ADCB) because the activity is DED-defined. Free Zone entities with overseas-only revenue can find international banks (HSBC, Standard Chartered) more receptive because the AML profile is clearer.
VAT
Both pay VAT at 5% on taxable supplies once they pass the AED 375,000 registration threshold (or voluntarily from AED 187,500). Free Zone entities in Designated Zones get specific reverse charge treatment on goods moving in and out. This matters only for physical-goods businesses. Services do not benefit.
Visa quotas
Free Zone visa quotas are tied to the package and the workspace. IFZA from AED 12,900 starts at zero visas (1-visa package from AED 14,900); Meydan from AED 12,500 (1-visa pkg AED 14,500); AFZ Virtual Office from AED 5,565 (0 visa, 1-visa all-in from AED 13,141 with visa items bundled). Mainland quotas scale with the actual office square footage. For a team of 8+, Mainland often becomes the practical choice. For a solo founder or 2-3 person team, Free Zone is usually cheaper.
Cost rough cuts (2026, license-package only)
- Mainland LLC, year one all-in: AED 25,000 to AED 60,000+ depending on activity, office, and visas.
- IFZA Free Zone: license-package AED 12,900 (0 visa) to AED 20,900 (4 visa quota).
- DMCC Free Zone: license-package AED 35,484 (Basic Biz) to AED 120,000 (Jumpstart 3-yr).
- AFZ Virtual Office: AED 5,565 (0 visa) to AED 63,898 (10 visa all-in bundled).
- Shams Standard: AED 5,750 (Media) to AED 6,875 (Standard) license-only, AED 1,600 per visa quota slot on top.
- RAKEZ Commercial: AED 6,000 license, AED 4,000 per visa fully bundled, or Instant Lite AED 12,000 sealed (1 visa).
How we usually advise
For UK founders moving service-export businesses (B2B SaaS, consultancy serving non-UAE clients, IP holding), Free Zone wins on cost, banking simplicity, and the realistic shot at QFZP status. For founders selling into the UAE market (retail, F&B, UAE government contracting, professional services to local SMEs), Mainland wins on market access despite the slightly higher cost. The hybrid (Free Zone parent with a Mainland branch) exists but is rarely the cheapest answer for a single founder.
The simplest filter: write down your 5 biggest expected customers in year one. If 4 of them are outside the UAE, go Free Zone. If 4 of them are inside the UAE, go Mainland. The edge cases are where we earn our fee.
