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 and runs at least until the end of 2026. 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.
