De minimis headroom: a worked example
| Month | Cumulative qualifying revenue | Cumulative mainland revenue | Position |
|---|---|---|---|
| March | 4,200,000 | 60,000 | Comfortable |
| June | 8,900,000 | 185,000 | Comfortable |
| September | 13,100,000 | 410,000 | Watch: mainland growing faster than total |
| October | 14,400,000 | 560,000 | Review now, while two months remain |
| November | 15,800,000 | 690,000 | Options: defer, route through a mainland entity, or accept |
| December (projected) | 17,200,000 | 880,000 | Decision point, and it was visible in September |
The point of the table is the September row. Mainland revenue growing faster than total revenue is the early signal, and it appears months before the threshold question becomes urgent. A business tracking this quarterly sees it; one reviewing annually does not.
Figures are illustrative. The de minimis threshold is defined by reference to total revenue with a cap, so run your own numbers rather than reasoning from these.
Unpacking that
The de minimis mechanism is what makes this worth understanding properly, because it behaves differently from almost every other threshold in tax.
Most thresholds are marginal. Cross the VAT registration threshold and you register; cross the AED 375,000 corporate tax band and you pay 9 per cent on the excess. The consequence is proportionate to how far over you are.
De minimis is not like that. It is a cliff. Non-qualifying income within the threshold is fine and taxed at 9 per cent above AED 375,000, with qualifying income still at 0 per cent. Non-qualifying income above the threshold means you cease to be a QFZP, for that period, and typically for the following four.
So the marginal dirham of mainland revenue that takes you over is not worth 9 per cent. It is worth the entire 0 per cent rate on your qualifying income, for five years.
That asymmetry is the single most important thing for a free zone business to understand, and it is why the tracking discipline matters far more than the technical definitions.
Broadly what qualifies and what does not
The categories are defined by decision and the detail matters, so treat this as orientation rather than a determination:
- Generally qualifying: transactions with other free zone persons where they are the beneficial recipient, and certain defined activities such as manufacturing, processing, holding shares and securities, fund management, treasury services to related parties, and logistics
- Generally non-qualifying: income from UAE mainland customers, income from a domestic or foreign permanent establishment, and income from immovable property other than commercial property in the zone transacted with free zone persons
- Excluded activities: a defined list which, even when transacted with free zone persons, does not qualify
- Natural person customers: treatment depends on the activity and needs checking rather than assuming
- Foreign customers: frequently qualifying, but the analysis depends on the activity and on where it is performed
The category businesses most often misjudge is transactions with free zone persons that are not the beneficial recipient, selling to a free zone intermediary that on-sells to the mainland. The counterparty being in a free zone is not sufficient on its own.
Why mainland revenue accumulates unnoticed
The failure pattern is consistent enough to describe in advance, and nobody in it is being careless.
A free zone trading company sells to export markets and comfortably qualifies. A UAE mainland customer approaches it, good margin, easy logistics, prompt payment. Sales takes the business. Nobody in sales has any reason to think of a customer’s location as a tax event, and nobody in finance sees it until the year end.
By December, mainland revenue has passed the de minimis threshold. The business has traded profitably all year and lost its 0 per cent rate on everything, for this period and the following four.
What prevents it is not sophistication. It is a field on the customer record marking counterparty type, a monthly report of the mainland proportion, and somebody looking at it. That is a configuration task, and it is the highest-return hour a free zone finance function can spend.
What to do when you are approaching the threshold
Identified early, this is a decision with several options. Identified late, it is a report.
Defer. Where timing is flexible, moving a shipment or an invoice into the following period keeps the current one inside the threshold. Legitimate where it reflects the commercial arrangement, and not where it is purely presentational.
Route through a mainland entity. Where mainland business is genuinely strategic and growing, a separate mainland company is usually the structural answer. That takes time to establish, which is another reason for early detection.
Accept the loss deliberately. Sometimes the mainland business is worth more than the status, particularly for a company whose qualifying income is modest. That is a legitimate answer, and it is a very different thing when chosen rather than discovered.
Elect out. A company can elect to be taxed at standard rates, which for some businesses is simpler than maintaining a fragile QFZP position.
The common thread is that all four require time. None of them are available in month fourteen.
What trips people up
- Treating de minimis as a marginal threshold. It is a cliff: exceeding it costs the status, not the excess.
- Assuming a free zone counterparty is enough. They generally need to be the beneficial recipient.
- Not tagging revenue by counterparty type, so the mainland proportion is invisible until year end.
- Reviewing annually rather than quarterly, and missing the early signal entirely.
- Assuming all foreign income qualifies. It depends on the activity and where it is performed.
- Forgetting that qualifying income still requires the other four conditions to hold.
- Discovering the position after the year end, when none of the four responses remain available.
How to act on this
- Add a counterparty type field to your customer records: free zone, mainland, foreign.
- Report the mainland proportion monthly and watch whether it is growing faster than total revenue.
- Quantify de minimis headroom and project the date it would be breached.
- Review with two months of the year left, when the four responses are still available.
- If mainland business is strategic, start on the mainland entity now rather than at the threshold.

Frequently Asked Questions
What is qualifying income for a free zone company?
Income from qualifying activities that attracts the 0 per cent rate for a QFZP, broadly transactions with other free zone persons who are the beneficial recipient, plus certain defined activities. Income from UAE mainland customers is generally non-qualifying.
What is the de minimis threshold?
The permitted level of non-qualifying income a QFZP can have while keeping the status. It is defined by reference to total revenue with a cap, so the figure depends on your own numbers rather than being a fixed amount.
What happens if we exceed it?
You cease to be a QFZP for that tax period and typically for the following four. You do not simply pay 9 per cent on the excess. That asymmetry is the single most important thing to understand about this threshold.
Is selling to a mainland customer always non-qualifying?
Generally yes, and that is the most common source of non-qualifying revenue. It is permitted within the de minimis threshold, which is why tracking the proportion month by month matters more than the technical definitions.
Does selling to another free zone company always qualify?
Not automatically. The counterparty generally needs to be the beneficial recipient. Selling to a free zone intermediary that on-sells to the mainland is the case businesses most often misjudge.
How do we track this practically?
A counterparty type field on the customer record, and a monthly report of the mainland proportion. It is a configuration task rather than an analytical one, and it is the highest-return hour a free zone finance function can spend.
What is the early warning sign?
Mainland revenue growing faster than total revenue. That appears months before the threshold question becomes urgent, and it is visible to anyone tracking quarterly and invisible to anyone reviewing annually.
What are our options if we are close?
Defer where timing is genuinely flexible, route mainland business through a separate mainland entity, accept the loss of status deliberately, or elect out to standard rates. All four require time, which is why detection in month ten matters and month fourteen does not.
Is losing the status always bad?
Not necessarily. For a company whose qualifying income is modest and whose mainland business is growing, the mainland revenue may be worth more than the rate. That is a legitimate conclusion, but a very different thing chosen deliberately than discovered at a year end.
