The most expensive assumption in UAE Corporate Tax is that a free zone licence means 0 percent. It does not. Free zone entities are taxable persons. What a free zone offers is the possibility of a 0 percent rate on qualifying income, if the entity meets every condition to be a Qualifying Free Zone Person.
The conditions
QFZP status generally requires that the entity maintains adequate substance in the free zone, derives qualifying income, has not elected into the standard regime, complies with transfer pricing requirements and documentation, and prepares audited financial statements. That last requirement alone puts an obligation on many small free zone companies that they did not previously have.
The de minimis rule
A limited amount of non-qualifying revenue is tolerated. Exceed the de minimis threshold and the consequence is not a partial adjustment: QFZP status can be lost, and the standard regime applies. This is why the rule deserves attention out of proportion to the sums involved. A relatively small amount of the wrong kind of income can change the treatment of everything.
Mainland income is the usual cause
Supplying services directly to mainland UAE customers is the most common way free zone businesses generate non-qualifying revenue. Many companies do this routinely without recognising the tax consequence, because the commercial arrangement predates Corporate Tax entirely.
Non-qualifying income is taxed differently
Where income does not qualify, it is taxed at 9 percent, and the AED 375,000 band that applies to ordinary taxable persons is not available in the same way. Free zone businesses cannot assume the small-profit cushion that mainland companies rely on.
You still register and still file
None of this removes the compliance obligation. A QFZP with entirely qualifying income and a 0 percent rate registers for Corporate Tax and files a return. The 0 percent outcome is a result reported in the return, not a reason to skip it.
What to check
- Whether your actual revenue streams meet the qualifying income definition, activity by activity
- How much mainland-facing revenue you have, measured against the de minimis threshold
- Whether you have the substance in the free zone that the conditions require
- Whether audited financial statements are being prepared
If your free zone status has been assumed rather than tested, test it before a return depends on it. See Corporate Tax filing and audit support.
