UAE corporate tax for free zone companies is widely described as “0%,” and that shorthand costs businesses money. A company registered in a UAE free zone is a Taxable Person under the corporate tax law — the same as a mainland company. The 0% rate is not a birthright of your free zone licence; it is a regime you have to qualify for, tax period after tax period, and the conditions are stricter than most owners assume.
Get them right and your Qualifying Income is taxed at 0%. Get one wrong and you are not merely nudged — you lose Qualifying Free Zone Person status for the current year and the four that follow. Here is what actually decides it.
What UAE corporate tax for free zone companies actually taxes
The starting point in the Federal Tax Authority’s Free Zone Persons guide is blunt: a Free Zone Person only benefits from 0% if it is a Qualifying Free Zone Person (QFZP), and even then the 0% applies solely to Qualifying Income. Any Taxable Income that is not Qualifying Income is taxed at 9%. So the free zone benefit is not a blanket exemption on the entity — it is a 0% carve-out for a specific slice of income, sitting on top of an entity that is otherwise inside the tax net.
For comparison, a company that is not a QFZP falls under the standard rule: 0% on taxable income up to AED 375,000 and 9% on the excess. A free zone company that loses its status therefore does not become exempt — it simply lands on the ordinary 9% ladder.
The practical line runs through your customers. Broadly, income a free zone company earns from other free zone businesses, and much of what it earns from outside the UAE, can fall within Qualifying Income; income earned from mainland UAE customers generally does not and is taxed at 9%, unless it stays inside the de minimis allowance described below. That single distinction — who your customers are and where they sit — is what most free zone owners have never mapped against their own revenue mix.
The five conditions that keep you at 0%
The FTA guide sets out the conditions a Free Zone Person must meet, in every tax period, to be a QFZP.
1. Adequate substance in the free zone
You must carry out your core income-generating activities — the ones actually earning the 0% income — inside a free zone, with adequate assets, qualified employees and operating expenditure to match. A brass-plate presence does not survive an FTA review.
2. Qualifying Income
The income you want taxed at 0% has to fall within the categories the law defines as Qualifying Income. Income from Excluded Activities, or from the wrong kind of mainland business, is not in that bucket.
2a. Note on Excluded Activities
The law names specific Excluded Activities that never earn 0% even inside a free zone. If a meaningful share of your revenue comes from them, the free zone regime may be the wrong structure entirely — better to know that before you file than after an assessment.
3. No election out
You must not have elected to be taxed under the standard corporate tax rules. Some businesses do choose this — but it is a deliberate, documented decision, not an accident.
4. Arm’s length and transfer pricing
Transactions with Related Parties must follow the arm’s length principle, and you must keep the transfer pricing documentation the law requires. This is where intra-group free zone structures most often come undone.
5. The de minimis limit
Your non-qualifying revenue must not exceed the lower of AED 5,000,000 or 5% of your total revenue. Breach that ceiling — even with a modest amount of mainland or excluded business — and you fail the whole test.
The audit condition nobody budgets for
On top of the five, the FTA guide is explicit on a point that catches smaller free zone entities: a QFZP must prepare and maintain audited financial statements, regardless of the amount of revenue it earns. There is no small-company exemption from the audit. If you intend to claim 0%, an audit is not optional and it is not something to improvise after year-end — the books have to be built for it from day one. Our corporate tax and outsourced accounting teams treat this as the first item, not the last.
What failing actually costs
The consequence of slipping is structural, not a one-off fine. Under the FTA guide, a Free Zone Person that fails the conditions — or elects out — ceases to be a QFZP from the beginning of that tax period and for the four subsequent tax periods. That is five years on the standard 9% regime before you can even re-test for 0%. A single year’s de minimis breach, in other words, is a five-year decision.
Deadlines and reliefs sit on top
Qualifying for 0% does not remove your filing duty. Every taxable free zone person must register and file, and the return and tax payment fall due within nine months of the end of the tax period — we set out exactly how that date is computed in our note on the UAE corporate tax filing deadline. Separately, Small Business Relief remains available to certain resident persons under a revenue threshold, but it is a different election with its own conditions, not a substitute for QFZP status.
If your business runs across borders, the interaction with residency and treaty positions matters too; a tax residency certificate is often part of the same conversation. The through-line is simple: the 0% is real, but it is earned every year against a checklist — and the cost of assuming it is five years of 9%.
