Free Zone vs. Mainland: Does Your Company Still Get 0% Corporate Tax?

A lot of free zone business owners still assume their 0% Corporate Tax rate is a permanent, automatic feature of being in a free zone. It isn't. It's a status you have to actively qualify for, every single year.

Qualifying Free Zone Person: not automatic

To access the 0% rate, your company needs to be recognized as a Qualifying Free Zone Person (QFZP) under FTA rules. That means meeting a specific set of conditions — being legally incorporated in a UAE free zone, maintaining adequate economic substance there (real premises, real staff, real activity, not just a licence on paper), and earning what the FTA defines as "qualifying income."

What counts as qualifying income

Qualifying income generally covers revenue from approved business activities and transactions with other free zone entities, along with certain incidental income, provided all the regulatory conditions are met. Income that falls outside these categories is treated as non-qualifying, and it's taxed differently.

The de minimis rule

You're allowed a small amount of non-qualifying revenue without losing your status — specifically, the lower of AED 5,000,000 or 5% of your total revenue for the year. Go over that threshold, and the consequences aren't limited to just the excess amount.

The part that surprises people

If your business fails even one of the QFZP conditions in a given year — substance, income mix, the de minimis limit, or the required audited financials — the 0% rate doesn't just shrink. Your entire taxable income for that year becomes subject to the standard 9% Corporate Tax rate, not just the portion that caused the issue.

Mainland, by comparison

Mainland companies don't have this qualifying test to navigate — they're simply taxed at 0% up to AED 375,000 in taxable income and 9% above that, the same structure every UAE business eventually lands on if it doesn't hold (or doesn't want) free zone status. You can confirm your registration status any time via the EmaraTax portal.

What to check now

If you're a free zone company, don't assume last year's 0% rate carries forward automatically. Review your economic substance, your income mix, and your documentation for the current year specifically — this is one area where an annual check really matters.
