The promise of a UAE free zone is 0% corporate tax — but only if your company is a Qualifying Free Zone Person (QFZP). The rules are strict, easy to fail, and there is a hard filing deadline this year. Here is who actually qualifies for the 0% rate in 2026, and what the 30 September deadline means for you.
9% or 0%? The QFZP test decides
The UAE applies 9% corporate tax on profits above AED 375,000. A free-zone company can instead enjoy 0% on its qualifying income — but only if it meets every QFZP condition. Miss a single one and you lose QFZP status entirely, becoming subject to 9% for that year and the following four. It is all-or-nothing.
The conditions you must keep
- Adequate substance — real, full-time staff, premises and operating expenditure in the free zone; decisions made in the UAE.
- Qualifying income — chiefly transactions with other free-zone businesses and approved qualifying activities; non-qualifying revenue must stay within the de minimis limit.
- Audited financial statements — mandatory for QFZPs.
- Transfer-pricing compliance and no election to be taxed at the standard rate.
The 30 September 2026 deadline
If your company’s financial year ended on 31 December 2025, your UAE corporate-tax return and payment are both due by 30 September 2026. That follows the nine-month rule: both filing and payment fall due within nine months of your financial year-end — so if your year-end differs, your deadline shifts accordingly. Late or incorrect filing risks penalties and your QFZP position; this is not a deadline to drift past.
The most common ways to lose 0%
Earning too much non-qualifying income, thin substance (a “letterbox” presence), missing the audit, or sloppy transfer pricing. Founders who assumed “free zone = automatic 0%” are exactly who the regime catches. For the underlying rules, see our Qualifying Free Zone Person guide.
Plan it into your setup
QFZP status is easier to keep than to recover. Build substance and activity classification in from the start — our Dubai free-zone setup cost and free zone vs mainland guides help you choose a structure that supports it.
Frequently asked questions
Who qualifies for 0% corporate tax in a UAE free zone?
A Qualifying Free Zone Person that meets every condition: adequate substance, qualifying income within the de minimis limit, audited accounts, and transfer-pricing compliance. Failing any one means 9% applies.
When is the UAE corporate tax filing deadline in 2026?
Both your return and payment are due within nine months of your financial year-end. For a 31 December 2025 year-end, that means 30 September 2026.
Does a free-zone company automatically get 0% tax?
No. The 0% rate applies only to a Qualifying Free Zone Person on its qualifying income; non-qualifying income and failed conditions trigger 9%.
What happens if I lose QFZP status?
You become subject to 9% corporate tax for that tax year and the four subsequent years.
The bottom line
The UAE’s 0% free-zone rate is real but conditional — and 30 September is a hard date. Get substance, income classification and your audit right, and file on time. Talk to our UAE team to review your QFZP position.
