UAE corporate tax: who actually pays the 9%?
What UAE corporate tax actually is
The UAE introduced a federal corporate tax in June 2023, at a headline rate of 9%. Before that, corporate tax at the federal level was effectively zero for most businesses (oil companies and foreign banks were the historic exceptions). So the 9% figure gets a lot of attention, but the more useful question is who actually ends up paying it.
The short answer: mainland UAE companies with taxable profits above AED 375,000, and free zone companies that fail to qualify for the 0% rate.
The standard rate structure
| Taxable profit band | Rate |
|---|---|
| AED 0 to AED 375,000 | 0% |
| Above AED 375,000 | 9% |
These rates apply to UAE-resident entities and to foreign entities with a permanent establishment in the UAE. The AED 375,000 threshold is a genuine relief for genuinely small businesses, not a loophole.
The free zone 0% rate, and why it is not automatic
This is where most UK founders and expats get caught out. Free zones have always been sold on the “0% tax” promise, and under the new regime, that remains technically true, but only if the company qualifies.
To pay 0% on qualifying income, a free zone company must be a Qualifying Free Zone Person (QFZP). That means:
- Maintaining adequate substance in the UAE (real activity, not just a registered address)
- Earning income that counts as qualifying income
- Not earning income from excluded activities
- Having audited financial statements
If the company ticks all those boxes, qualifying income is taxed at 0%. Income that does not qualify is taxed at 9%.
The critical point: one bad revenue stream can affect the whole company’s status for a tax year. Earning meaningful income from mainland UAE customers, or from an excluded activity like lending or holding IP exploited in the UAE, means the 0% protection can fall away entirely for that period. The Federal Tax Authority has published guidance on this, but it is genuinely technical territory.
What ‘substance’ means in practice
Substance is not just a box to tick. The Federal Tax Authority looks at whether the company’s core income-generating activities genuinely happen in the UAE. For a services business that means active management, real decision-making on UAE soil, and some operational presence. A dormant shell with a registered agent but no activity is not a QFZP, whatever the licence says.
This matters more than most free zone sales pitches suggest. Substance requirements have been part of the UAE’s economic landscape since 2019 (Economic Substance Regulations), and the corporate tax framework builds on them.
Small business relief, a separate, simpler option
Businesses with revenue under AED 3 million can elect for small business relief, treating taxable income as zero for the relevant period. This election was available from the first tax period. Ministerial Decision No. 131 of 2026 extended it to tax periods ending on or before 31 December 2029, and you still have to register for corporate tax and make the election on your return. It is a temporary measure, not a permanent structural option, and it is not available to free zone companies already using the qualifying income regime.
For very early-stage businesses, it simplifies compliance significantly. But it is time-limited and revenue-capped, so building a plan around it is not sensible.
What this means if you have moved from the UK
Most UK founders setting up in a UAE free zone are targeting the 0% qualifying rate. That is achievable, but it requires the company to be structured, operated and documented properly, not just incorporated and left to run.
Common mistakes the families and founders we work with arrive with:
- A free zone licence with no substance to back it up
- Mixed mainland and free zone income with no analysis of the qualifying impact
- Assuming the 0% rate is automatic because the sales agent said so
- A UK company still active alongside the UAE entity, with unclear management and control
None of these are fatal, but each one needs to be understood and addressed. The corporate tax position is also only one part of the picture. For UK leavers, the interaction with UK tax residency rules, the statutory residence test, and the UK’s own corporation tax (if a UK entity is involved) all matter too.

Questions people ask
Do UAE free zone companies pay corporate tax?
They can pay 0% on qualifying income, but it is not automatic. The company must be a Qualifying Free Zone Person (QFZP), meet substance requirements, earn income that counts as qualifying, and not have any income that drags it onto the standard 9% rate. Failing any of those conditions collapses the 0% treatment for that period.
What counts as 'qualifying income' under UAE corporate tax?
Broadly, income from transactions with other free zone businesses and certain cross-border income. Income from mainland UAE customers or from excluded activities, banking, insurance, finance, intellectual property used in the UAE, and a few others, is non-qualifying. Even one significant mainland revenue stream can affect the company's status for that year.
Does the AED 375,000 threshold mean small companies pay nothing?
Not quite. The AED 375,000 is the taxable income threshold below which 0% applies under the standard rate structure, but only if the company is subject to corporate tax in the first place. QFZPs operating under the 0% qualifying rate are largely outside that band anyway. The small business relief for revenue under AED 3 million is a separate, time-limited election.
I set up a UK Ltd before moving to Dubai. Is that company caught by UAE corporate tax?
Probably not directly, but the picture is more complicated than that. UAE corporate tax applies to UAE-resident entities. A UK Ltd remains UK tax-resident and pays UK corporation tax. The issue for most UK founders is that after they move to Dubai, questions arise about where the UK company is actually managed and controlled, which can create UAE exposure or UK residency complications of its own.
We hear about 'substance' requirements, what does that mean in practice?
To hold onto the 0% qualifying rate, a free zone company must have genuine economic substance in the UAE: real activity, staff or management presence, and core income-generating activities happening in the free zone. A company that exists on paper with no real operations risks losing its qualifying status. The Federal Tax Authority can and does review this.
