The De Minimis Rule: The 5% / AED 5 Million Test That Decides Your Free Zone Tax Rate
For businesses operating in a UAE Free Zone, the 0% Corporate Tax rate can be one of the most valuable advantages of qualifying as a Qualifying Free Zone Person (QFZP). But this benefit is not automatic simply because a company is registered in a Free Zone.
One of the key conditions is the de minimis requirement â a test that limits the amount of non-qualifying revenue a Free Zone business can earn while maintaining its QFZP status.
The rule is straightforward in principle: a QFZP's non-qualifying revenue must not exceed the lower of 5% of total revenue or AED 5 million during the relevant Tax Period.
Understanding how this calculation works is essential because crossing the permitted limit can have significant Corporate Tax consequences.
What Is the De Minimis Rule?
The de minimis rule is designed to give Free Zone businesses limited flexibility to earn a small amount of revenue that does not qualify for the UAE's preferential Free Zone Corporate Tax regime.
Under the current rules, the requirement is satisfied when a QFZP's non-qualifying revenue does not exceed the lower of:
5% of total revenue, or
AED 5 million
The important word is "lower." Businesses cannot simply assume that they have an AED 5 million allowance.
For example, if a company has total revenue of AED 20 million, 5% is AED 1 million. Therefore, its maximum permitted non-qualifying revenue would be AED 1 million, not AED 5 million.
This calculation makes the de minimis test particularly important for businesses with different revenue streams.
How the 5% / AED 5 Million Test Works
Consider a UAE Free Zone company with total revenue of AED 40 million.
Five percent of AED 40 million is:
AED 40 million à 5% = AED 2 million
The company therefore compares:
5% of total revenue = AED 2 million
AED 5 million = AED 5 million
The lower amount is AED 2 million.
This means the company must keep its non-qualifying revenue at or below AED 2 million to satisfy the de minimis requirement.
Now consider a smaller company with total revenue of AED 120 million.
Five percent would equal AED 6 million. Since the rule uses the lower amount, the maximum permitted non-qualifying revenue would still be AED 5 million.
This creates a practical ceiling: the de minimis threshold can never exceed AED 5 million.
Why Does Non-Qualifying Revenue Matter?
Not all revenue earned by a Free Zone business automatically qualifies for the 0% rate.
The UAE Free Zone Corporate Tax regime distinguishes between Qualifying Income and income that does not meet the qualifying conditions. Certain activities and transactions may fall outside the definition of Qualifying Income.
The UAE Ministry of Finance has explained that income from certain Excluded Activities and other income that is not Qualifying Income can affect a Free Zone Person's eligibility, subject to the de minimis requirements.
The rules covering qualifying and excluded activities were also updated in 2025 through Ministerial Decision No. 229 of 2025, which replaced the earlier Ministerial Decision No. 265 of 2023.
Therefore, businesses should not calculate the 5% test in isolation. They first need to correctly classify their revenue.
What Happens If You Fail the De Minimis Test?
This is where the rule becomes particularly important.
If a Free Zone Person fails the de minimis requirement, it can lose its status as a Qualifying Free Zone Person. The consequences are not limited to simply paying 9% on the excess revenue.
FTA guidance explains that when a QFZP fails the conditions, it ceases to qualify for the Free Zone regime for the relevant Tax Period and the four subsequent Tax Periods.
In practical terms, a business that accidentally crosses the threshold could lose access to the preferential regime for a multi-year period.
Once the QFZP conditions are no longer met, the business is generally treated under the ordinary UAE Corporate Tax rules. The standard Corporate Tax rate is 9% on Taxable Income above AED 375,000, rather than the 0% rate available on qualifying income under the Free Zone regime.
That is why monitoring the de minimis threshold should be part of regular tax planning rather than something checked only when preparing the annual tax return.
A Common Mistake: Looking Only at Total Revenue
One of the biggest mistakes Free Zone businesses can make is focusing only on their overall turnover.
A company may have substantial revenue and still potentially qualify as a QFZP, provided its activities, income, substance and other conditions meet the applicable requirements.
At the same time, a business with relatively modest non-qualifying revenue can potentially breach the de minimis test if that revenue represents more than 5% of its total revenue.
For example:
Total revenue: AED 10 million
5% threshold: AED 500,000
Non-qualifying revenue: AED 600,000
Although AED 600,000 is far below AED 5 million, it exceeds the applicable AED 500,000 threshold. The business therefore needs to carefully assess the consequences of failing the requirement.
What Should Free Zone Businesses Do?
Businesses seeking to preserve QFZP status should adopt a proactive approach.
First, maintain accurate accounting records and separate revenue streams based on their tax treatment. Second, monitor non-qualifying revenue throughout the year instead of waiting until year-end. Third, review transactions involving related parties, customers and different jurisdictions carefully.
Businesses should also keep supporting documentation demonstrating how revenue has been classified and how the de minimis calculation was performed.
The UAE's Free Zone regime provides significant opportunities, but the 0% Corporate Tax rate comes with conditions. The de minimis test is one of the most important safeguards businesses need to monitor.

Frequently Asked Questions
What is the de minimis rule under the UAE Free Zone Corporate Tax regime?
It is a test that caps the amount of non-qualifying revenue a Qualifying Free Zone Person (QFZP) can earn while keeping its 0% Corporate Tax status. Non-qualifying revenue must stay within the lower of 5% of total revenue or AED 5 million.
What is the de minimis threshold for a QFZP?
The threshold is the lower of 5% of total revenue or AED 5 million for the relevant Tax Period. Businesses must compare both figures and apply whichever is smaller.
How is the 5% de minimis threshold calculated?
Multiply total revenue for the Tax Period by 5%. Compare the result with AED 5 million, and the lower of the two figures becomes the maximum permitted non-qualifying revenue.
Can the de minimis threshold ever exceed AED 5 million?
No. Even where 5% of total revenue is higher than AED 5 million, the rule caps the threshold at AED 5 million. This creates a practical ceiling that never rises above that amount.
What counts as non-qualifying revenue?
Non-qualifying revenue generally includes income from Excluded Activities and other income that does not meet the definition of Qualifying Income under the Free Zone Corporate Tax rules, including the updated activity rules in Ministerial Decision No. 229 of 2025.
What happens if a Free Zone Person exceeds the de minimis threshold?
The business can lose its QFZP status. FTA guidance confirms that failing the de minimis conditions means the entity ceases to qualify for the Free Zone regime for the relevant Tax Period and the four subsequent Tax Periods.
Does failing the de minimis test affect only the excess revenue?
No. Losing QFZP status is not limited to taxing the excess amount at 9%. The business is generally moved onto the standard Corporate Tax rules, with 9% applying to Taxable Income above AED 375,000, for the full multi-year period the loss of status covers.
Is the de minimis test based only on total revenue?
No. Focusing only on overall turnover is a common mistake. A business can still breach the de minimis test with relatively modest non-qualifying revenue if that revenue exceeds 5% of its total revenue, even when it is far below AED 5 million.
How often should businesses monitor the de minimis threshold?
Monitoring should happen throughout the year rather than only at year-end. Businesses should maintain accurate, separated revenue records and review related-party and cross-jurisdiction transactions regularly to track their position against the threshold.
