You set up in a UAE free zone expecting a straightforward 0% corporate tax rate, and then your accountant tells you part of your revenue is taxed at 9% anyway. This catches a lot of founders off guard, because the rules around free zone qualifying income are more specific than the marketing brochures ever explain. Not every dirham a free zone company earns gets the 0% rate — only income that meets a defined set of conditions does, and getting this wrong can mean an unexpected tax bill or, worse, losing the 0% regime altogether for five years.
Here’s what actually counts as qualifying income, what doesn’t, and how to keep your free zone company on the right side of the line.
The Two Rates Every Free Zone Company Should Know
A UAE free zone company that qualifies as a Qualifying Free Zone Person (QFZP) is taxed at two different rates on the same tax return: 0% on Qualifying Income, and 9% on Taxable Income that isn’t Qualifying Income. You don’t choose one or the other — both can apply within the same financial year, depending on where each stream of revenue comes from and who it’s earned from.
This means the real work isn’t asking “am I in a free zone?” It’s asking “which parts of my revenue actually qualify?” That distinction determines your effective tax rate far more than your trade licence does.
What Counts as Free Zone Qualifying Income
Broadly, income qualifies for the 0% rate when it comes from transactions with other free zone entities that are themselves the “beneficial recipient” of the goods or services, from transactions with parties outside the UAE, or from a defined list of Qualifying Activities regardless of where the customer sits. Qualifying Activities typically include things like manufacturing, holding of shares and securities, fund and wealth management, headquarter services to related parties, treasury and financing services to related parties, and — following recent Ministerial Decision updates — activities such as commodity trading and dealing in qualifying commodities.
The important nuance: dealing with another free zone company only helps you if that counterparty is the actual beneficial recipient of what you’re providing, not simply routing it through to a mainland business. The Federal Tax Authority looks past the invoice to who ultimately benefits.
What Doesn’t Qualify — and Where Businesses Get Caught Out
Income from Excluded Activities does not qualify for the 0% rate, no matter who the customer is or where they’re based. This generally includes transactions with individuals (except for a short list of activities like ownership of certain intellectual property or aircraft), most banking, insurance, and finance and leasing activities outside a treasury context, and ownership of immovable property other than commercial property located within a free zone when the counterparty is another free zone person.
The most common trap for growing free zone SMEs is simpler than any of that: selling to UAE mainland customers. Revenue from mainland UAE sales generally falls outside Qualifying Income and is taxed at 9%, unless it flows through a specific structure such as a qualifying distributor arrangement. If your free zone company has been quietly picking up mainland clients as it’s grown, that revenue is very likely sitting in the 9% bucket already.
The De Minimis Threshold You Don’t Want to Cross
There’s some breathing room built into the rules. A de minimis threshold allows a limited amount of non-qualifying revenue — the lower of 5% of total revenue or AED 5 million — without disqualifying the company’s overall QFZP status. Income above that threshold doesn’t just get taxed at 9%; if you breach it, you can lose Qualifying Free Zone Person status entirely, and with it the 0% rate on income that would otherwise have qualified, for the current year and the following four years.
That five-year lockout is the real risk. It’s why this isn’t a once-a-year compliance exercise — free zone businesses with any mainland sales, individual clients, or excluded activities on their books need to track the qualifying-versus-non-qualifying split throughout the year, not just at filing time.
Staying on Top of Substance and Documentation
Qualifying for the 0% rate isn’t only about the nature of your income — you also need to demonstrate adequate substance in the free zone: appropriate assets, qualified employees, and operating expenditure relative to your activities. On top of that, you need records that clearly separate qualifying from non-qualifying income and support your transfer pricing position on any related-party transactions. If you’re already working through your corporate tax registration and relief position, the qualifying income analysis should sit alongside it, not as an afterthought once returns are due.
In practice, this means your bookkeeping needs to tag revenue by counterparty and activity type from day one, not reconstruct it retroactively. Free zone businesses that build this into their monthly close save themselves a scramble — and a much bigger tax exposure — at year end.
Frequently asked questions
Does every free zone company automatically get the 0% corporate tax rate?
No. You first need to qualify as a Qualifying Free Zone Person by meeting substance, activity, and income conditions, and even then only your Qualifying Income is taxed at 0% — any non-qualifying income is taxed at the standard 9% rate.
What happens if my free zone company sells to mainland UAE customers?
That revenue generally does not count as Qualifying Income and is taxed at 9%, unless it’s structured through an approved arrangement such as a qualifying distributor. It’s one of the most common reasons free zone SMEs end up with mixed-rate tax bills.
What happens if I go over the de minimis threshold for non-qualifying income?
Exceeding the lower of 5% of total revenue or AED 5 million in non-qualifying income can cause you to lose Qualifying Free Zone Person status altogether, applying the 9% rate to income that would have otherwise qualified — and you can be locked out of the 0% regime for the following four years as well.
If you’re not sure how much of your free zone company’s revenue actually qualifies, it’s worth getting a clear answer before your next filing rather than after.
