The most expensive misunderstanding in UAE corporate tax is also the simplest. A business calculates, correctly, that it will owe nothing — and concludes that the regime therefore does not apply to it.
Registration and liability are separate obligations. A business expecting a 0% outcome, whether through Qualifying Free Zone Person status or through Small Business Relief, is still required to register with the Federal Tax Authority and still required to file a return. The administrative penalty for registering late is AED 10,000, and it is charged without reference to how much tax was due.
The three ways a business arrives at 0%
Taxable income below AED 375,000. The standard rate is 9%, applied to taxable income above AED 375,000. Below that figure the rate is 0%. This is a threshold on taxable income rather than revenue, and it applies once per taxable person across all of its businesses rather than per licence.
Small Business Relief. A UAE resident person with revenue not exceeding AED 3 million may elect to be treated as having no taxable income for the period. In August 2026 the Ministry of Finance extended this relief — by Ministerial Decision No. 131 of 2026 — to tax periods ending on or before 31 December 2029, four years beyond the previously published end date of 31 December 2026. A great deal of published material, some of it written this year, still carries the old date.
Three conditions are routinely misread. The AED 3 million is a revenue test, not a profit test. It must have been met in the current period and every previous relevant period, so a single year above the line disqualifies the business permanently. And the relief is elected in the return — it is not granted automatically, which is another reason a return has to be filed.
Qualifying Free Zone Person status. A free zone company may achieve 0% on its qualifying income, and this is the route most often assumed and least often documented.
What Qualifying Free Zone Person status actually requires
It is a status a business qualifies for and then keeps satisfying, tested every year. The conditions are adequate substance in the free zone; qualifying income as defined; no election into the standard 9% regime; compliance with the arm’s length principle and transfer pricing documentation; audited financial statements prepared under IFRS; and the de minimis requirement.
Two points deserve emphasis because they are widely reported incorrectly.
The de minimis limit is that non-qualifying revenue must not exceed 5% of total revenue or AED 5 million, whichever is lower. It is frequently written as though the business may take the higher of the two. For any free zone company with total revenue below AED 100 million, the binding cap is the 5%.
The consequence of failing a condition is not confined to the year in which it happens. The entity loses qualifying status for that tax period and the four tax periods that follow — five in total — and is taxed at 9% on all of its income throughout, not merely on the slice that broke the test.
It is also worth noting that audited financial statements are a condition of the status itself. A free zone company that does not produce an audit cannot be a Qualifying Free Zone Person at any level of revenue.
The list of qualifying and excluded activities is set by Ministerial Decision No. 229 of 2025, which repealed and replaced Ministerial Decision No. 265 of 2023. Advice or articles still citing 265 are citing an instrument that no longer exists.
The deadlines, and the waiver most businesses have not heard of
The corporate tax return and the payment of any tax due are both required within nine months of the end of the tax period. For a financial year ending 31 December 2025, that is 30 September 2026. These are two separate obligations that happen to share a date — filing on time does not protect against the late payment charge if the money arrives afterwards.
Late filing carries AED 500 per month for the first twelve months and AED 1,000 per month thereafter. Late payment is charged at 14% per annum, monthly, on the unsettled amount.
Separately, the FTA’s late registration penalty waiver remains available. Where a business registered late, the AED 10,000 penalty can be waived if it files its return or annual declaration within seven months of the end of its first tax period, rather than the usual nine. Penalties already paid are credited to the EmaraTax account.
This initiative is very widely described as having expired on 31 July 2025. It did not, and it is not a calendar deadline at all: the seven months run from the end of each company’s own first tax period, so the operative date is different for every business. It applies only to the first tax period and only to the registration penalty — late filing and late payment penalties are untouched.
What we would actually check
For a business that expects to pay nothing, the work is not tax computation. It is evidence. Does the substance in the free zone match what the status assumes? Is the revenue split documented well enough to show the de minimis test was met? Do the audited accounts exist, and were they prepared on the right basis? Has the relief been elected, in the return, rather than assumed?
The honest answer is sometimes that the position does not hold and 9% should be planned for properly instead. That is a considerably better outcome than discovering it in year three, with four more years of exposure behind it.

FAQ
Do I have to register for corporate tax in the UAE if I pay 0%?
Yes. Registration and liability are separate questions. A business expecting a 0% outcome through Qualifying Free Zone Person status or Small Business Relief still has to register with the FTA and still has to file. Late registration carries an administrative penalty of AED 10,000 regardless of the tax due.
Has Small Business Relief been extended?
Yes. Ministerial Decision No. 131 of 2026 extended it to tax periods ending on or before 31 December 2029. The AED 3 million revenue threshold is unchanged.
Do free zone companies pay corporate tax in 2026?
Free zone companies are inside the regime like everyone else. A 0% rate applies to qualifying income where the company meets all of the Qualifying Free Zone Person conditions, tested every year.
What happens if we lose Qualifying Free Zone Person status?
The entity is taxed at 9% on all of its income for that tax period and the four tax periods that follow — five periods in total.
When is the corporate tax return due?
Nine months after the end of the tax period, with payment due on the same date.
