Key takeaways
- Mainland companies can trade anywhere in the UAE and pay 9% corporate tax above AED 375,000 — or nothing under Small Business Relief if revenue is AED 3 million or less.
- Free zone companies get 0% only on qualifying income and only as a Qualifying Free Zone Person, which requires substance, an audit and transfer pricing compliance.
- For small service businesses with UAE clients, a mainland company with Small Business Relief is often the cheaper structure.
The mainland-versus-free-zone question used to be about ownership and office costs. Since 2021, 100% foreign ownership is allowed for most mainland activities, and since 2023 corporate tax has changed the economics. In 2026, the decision turns on four things: who your customers are, where you need to operate, which tax regime you can actually qualify for, and what compliance you are willing to maintain.
Mainland vs free zone: side-by-side
| Factor | Mainland company | Free zone company |
|---|---|---|
| Where you can trade | Anywhere in the UAE, including government contracts | Within the zone and internationally; mainland trade generally via distributors or specific permits |
| Ownership | Up to 100% foreign for most activities | 100% foreign |
| Corporate tax | 0% to AED 375,000, 9% above | 0% on qualifying income if a QFZP; otherwise 9% |
| Small Business Relief | Available (revenue up to AED 3 million, to 2029) | Not available to QFZPs |
| Audit | Auditor required for LLCs under company law; mandatory for CT above AED 50m revenue | Usually required for licence renewal; mandatory for QFZP status |
| Transfer pricing | Required for related-party transactions | Required, and failure can cost QFZP status |
| Office | Physical office lease (Ejari) generally required | Flexi-desk options, but substance tests still apply for 0% |
| VAT and e-invoicing | Standard rules | Standard rules; Designated Zones have special VAT treatment for goods |
Which structure fits which business?
Mainland usually suits
- Service businesses whose clients are UAE companies or individuals.
- Retail, restaurants, clinics and contractors that need a local presence.
- Businesses bidding for government or semi-government work.
- Small businesses that can use Small Business Relief.
A free zone usually suits
- International trading, holding and headquarters companies.
- Businesses with free zone and overseas customers whose income is qualifying.
- Commodity traders using recognised price benchmarks.
- Businesses that need a specialist regulator, such as DIFC, ADGM or DMCC.
Worked example: a small consultancy
A consultancy expects AED 2 million in revenue from UAE corporate clients. In a free zone, most of that income is likely to be non-qualifying, so the 0% rate would not apply and the company would also need an audit to attempt QFZP status. On the mainland, the same business can elect Small Business Relief and pay no corporate tax while revenue stays within AED 3 million — with a lighter compliance load. The free zone looks cheaper on day one and costs more by year two.
Can you have both?
Yes. Many groups combine a free zone entity for international or qualifying activities with a mainland branch or subsidiary for local trade. This needs care: mainland income booked in the free zone entity is non-qualifying, and related-party pricing between the two must be at arm’s length.

Frequently asked questions
Is a free zone company tax-free in the UAE?
Not automatically. Only qualifying income of a Qualifying Free Zone Person is taxed at 0%.
Can a free zone company work with mainland clients?
It can in some cases, but income from mainland customers is generally non-qualifying and may cost the 0% rate. Some activities also need additional permits.
Is a mainland company more expensive to set up?
Often slightly, because of office lease requirements, but ongoing tax and audit costs can make it cheaper overall for local businesses.
Can I move from a free zone to the mainland later?
Yes, usually by setting up a new mainland entity or branch and transferring the business. Tax consequences of the transfer should be reviewed first.
