Free Zone Corporate Tax UAE: Inside the Limit, 0%?

A founder in a Dubai free zone called us with a spreadsheet he was proud of. His company had AED 40 million of qualifying revenue and AED 800,000 of other income from a side line that did not fit any qualifying activity. He had done what felt like the cautious thing. He had taxed the whole qualifying amount at 0% and the small slice at 9%, and he had written a cheque for tax on the slice to be safe. His question was simple: was the provision about right? On the careful reading of the rules, it was not. Inside the de minimis limit, that AED 800,000 slice becomes qualifying income itself. It is taxed at 0%, not 9%. He had not been cautious. He had paid tax that was not due, and he had learned the rule backwards. That backwards lesson is printed in current guides across the UAE.

Free zone corporate tax in the UAE invites one instinct: two rates exist, so income must split between them. Qualifying at 0%, everything else at 9%. For the residue the de minimis rule covers, that instinct is wrong. Inside the limit the slice is free. Outside it, everything is taxed, and the status that gave you 0% is gone for five tax periods in total. Guides that charge 9% inside the limit overstate the small bill. Guides that shrink a breach to one period understate the large one. Several have the price wrong in both directions at once.

Free Zone Corporate Tax UAE: The Three Buckets, Not Two

Start with the structure the careful account sets out. Every dirham of a Qualifying Free Zone Person's revenue lands in one of three places, not two. The first bucket is qualifying income in its own right: income from transactions with other free zone persons other than excluded activities, and income from the qualifying activities listed in Article 2 of Ministerial Decision No. 229 of 2025 when earned with anyone else. Manufacturing, processing, holding shares for investment, fund management, headquarters services, treasury work and the rest of that list sit here. This bucket is taxed at 0%.

The second bucket is the one this post is about. Call it other income: excluded activities, non-qualifying activities with non-free-zone persons, and transactions where the free zone counterparty is not the beneficial recipient. If it stays inside the limit, Cabinet Decision No. 100 of 2023 treats it as qualifying income, taxed at 0%. If it goes over, the consequence is not a 9% charge on the excess. The person ceases to be a Qualifying Free Zone Person from the start of that period and for the four that follow.

The third bucket never joins the other two. Income from a domestic or foreign permanent establishment, immovable property in the cases the decisions specify, and non-qualifying intellectual property income is taxable at 9% at any size, with no AED 375,000 band. Article 4(3) of Cabinet Decision No. 100 of 2023, as the careful account explains it, keeps that revenue out of both sides of the de minimis ratio. It can neither be sheltered by the limit nor blow it. We covered a neighbouring trap in our post on free zone qualifying activities and software income: being on the list matters, but so does knowing which bucket each line falls into once it is off the list.

The Limit Itself: Lower of 5% or AED 5 Million

Article 3 of Ministerial Decision No. 229 of 2025, which replaced Decision No. 265 of 2023 and applies from 1 June 2023, states the test in one sentence. The de minimis requirements are met where non-qualifying revenue in a tax period does not exceed 5% of total revenue or AED 5,000,000, whichever is lower. Both halves matter. A small company hits the percentage first. A large company hits the dirham cap first. On AED 40 million of total revenue, 5% is AED 2 million, so AED 2 million is the limit, not AED 5 million. On AED 200 million, 5% would be AED 10 million, so the AED 5 million cap is the limit. Founders who remember only one number remember the wrong limit for their own size.

Now run the worked example the careful account gives. AED 40 million of qualifying revenue plus AED 800,000 of other income gives total revenue of AED 40.8 million. Five percent of that total is just over AED 2 million. The AED 800,000 sits well inside it. On that account, the whole AED 40.8 million is taxed at 0%. Booking 9% on the small slice to be safe, in that account's own words, is not safe. It is just wrong. The example is an illustration from a named tax agent's guide, not a ruling on any real company, and we are not applying it to yours. The point is the shape of the rule: de minimis is a pass or fail gate, not a proportional carve-out. Inside the gate, the residue changes character. Outside it, the whole status changes.

What breach actually costs

Article 5(2), in the careful account's reading, sets the price of failing: the person ceases to be a Qualifying Free Zone Person from the beginning of the breach period and for the subsequent four. That is five periods at standard rates — 0% up to AED 375,000 and 9% above it — on income that would otherwise have qualified. A breach is not a one-year problem you fix next filing. Any forecast built on keeping 0% next year has to be rebuilt if this year's residue has already crossed the line.

Free Zone Corporate Tax UAE: How the Guides Charge the Slice Anyway

Against that account, set what a founder actually finds when he searches. A free zone tax guide's own rate table, in search extract this week, prices the position in a single row: QFZP, non-qualifying income within de minimis, 9% on that specific income only. The same guide's quick answer and breach row correctly state the five-period loss when the limit is exceeded. So one page holds both truths at once: the breach consequence is stated correctly, while the inside-the-limit price is stated as 9%. A reader who trusts the table provisions for a charge the careful account says does not exist, on the very page that warns him correctly about the larger danger.

A qualifying-income explainer goes further: a QFZP pays 0% only on qualifying income and 9% on everything else, from the first dirham, with no cushion. That sentence leaves no room for de minimis at all — no gate, and no difference between AED 10,000 of side income and AED 10 million. The same explainer correctly states the five-year breach consequence and the permanent-establishment carve-out. The reader is left to reconcile a page that knows about the breach, but not about the treatment inside the limit.

A free zone versus mainland comparison repeats the short version — 0% on qualifying, 9% on non-qualifying — then shrinks the other end: exceeding the threshold means all income is taxed at 9% for that tax period. No four following periods. A founder pricing a side line off that comparison overpays on the safe side and underprices crossing it. We saw the same pattern in our post on why 0% tax never meant zero penalties: the slogan survives, the costly detail does not.

The Four Categories That Are Always 9%

None of this means every small slice is free. Four categories are taxed at 9% regardless of size, and confusing them with de minimis residue is the second expensive error. Domestic permanent establishment income: if a free zone person has a mainland branch or a place of business that amounts to a domestic permanent establishment, the income attributable to it is taxable. Foreign permanent establishment income follows the same logic abroad. Immovable property income is taxable where the decisions specify it, notably non-commercial property anywhere and commercial property in a free zone let or sold to a non-free-zone person. Non-qualifying intellectual property income, the part that fails the qualifying IP formula in Decision No. 229 of 2025, is taxable as well.

Two consequences follow. First, do not test these four against de minimis at all: they are excluded from both sides of the ratio, so including them distorts the headroom you monitor all year. Second, do not assume a small amount is harmless because it is small. A small property receipt that is always taxable is still taxable, even in a year when your residue sits comfortably inside the limit at 0%. Size decides the de minimis buckets. Category decides this one. A bookkeeping system with no bucket field cannot tell the difference until filing, when it stops being cheap to fix. That discipline is the same one behind Dubai's bookkeeping panic.

A note on what 0% still requires

De minimis is only one condition. A QFZP must also maintain adequate substance, comply with transfer pricing, and prepare audited financial statements — mandatory for every QFZP regardless of revenue under Decision No. 84 of 2025 for periods from 1 January 2025. Passing de minimis while failing substance preserves nothing. See why attached statements are not audited statements.

How a Careful Finance Team Buckets Revenue Before Filing

The fix is not a better guide. It is a working paper built during the year, while revenue can still be understood, priced and, where lawful, planned. Here is the order we work in with free zone clients.

• Bucket every revenue line first, tax it second. For each line, ask in sequence: is it a qualifying activity under Article 2 of Decision No. 229 of 2025, or a transaction with a free zone person that is not an excluded activity? If yes, bucket one. Is it one of the four always-9% categories? If yes, bucket three, out of the ratio entirely. Everything left is de minimis residue, bucket two.
• Compute the limit on your own total, not on a remembered number. Take total revenue for the period as the decisions define it, excluding the always-9% revenue from both sides as the careful account describes, then apply the lower of 5% and AED 5 million. Write the limit, the residue and the headroom on one page. If headroom is thin, that page belongs in the monthly close, not in a folder opened at filing.
• Monitor headroom through the year. A single contract signed in November can move residue from 3% to 6% in one signature. The time to know that is before the contract is priced, when the founder can still decide whether the side line belongs in this company, in another entity, or not at all. A de minimis position reconstructed at filing is history. A position monitored monthly is a decision tool.
• Never provision 9% on residue inside the limit to be safe. Provisioning is supposed to state what is owed. A provision for tax the careful reading says is not due flatters caution and misstates the accounts, the forecast and any valuation built on them. If your adviser takes a different reading of Decision No. 100 of 2023, record that reading, its basis and its cost in writing. Do not let a rate table do it silently.
• Price a breach at five periods, never one. Any proposal that would push residue over the limit should be costed as standard-rate tax on the whole taxable income, above the AED 375,000 band, for the breach period and the four that follow. Very few side lines survive that arithmetic, which is precisely why the arithmetic has to be shown before the line is taken on.
• Choose the zone on the real income mix. At formation, a founder whose model already carries mainland, property or IP streams should be shown the bucket map and the five-period breach cost before the zone is chosen. A zone picked on a headline 0% and a licence fee, with no view of where the second and third revenue lines will land, is a tax position taken by accident.

This list does not declare any company a QFZP, price any company's slice, or tell any founder his status is safe or lost. Those calls live in that company's own revenue lines and audited statements, tested against Decisions No. 100 of 2023 and No. 229 of 2025. It puts the buckets in the bookkeeping, so the return is built from a position watched all year, not a split invented at the end of it.

An honesty note on sources

Everything material here is attributed to the account that states it. The careful position, the three buckets, the AED 800,000 against AED 40 million worked example, the warning that booking 9% on the small slice to be safe is just wrong, and the Article 4(3) exclusion of always-9% revenue from both sides of the ratio are from Fastlane's de minimis explainer, We'll Just Pay 9% on the Non-Qualifying Bit, which presents itself as an FTA-registered tax agent's account of Cabinet Decision No. 100 of 2023 and Ministerial Decision No. 229 of 2025. The limit itself, lower of 5% of total revenue or AED 5,000,000, is Article 3 of Ministerial Decision No. 229 of 2025, as published in summary. The rate table pricing non-qualifying income within de minimis at 9% on that specific income only, alongside its own correct five-period breach row, is from the Tax Consultant Dubai QFZP guide. The 0% only on qualifying income and 9% on everything else wording and the one-period breach wording are from the qualifying-income explainer and the free zone versus mainland comparison described in the text, in search extract. These are practitioner guides and summaries, not the Federal Tax Authority deciding your case. Read Decisions No. 100 of 2023 and No. 229 of 2025 and test your own revenue lines against them before you file, provision or price on anyone's say-so, including ours.

Inside the limit the slice is free. Outside it, everything is taxed, for five years. If your current return splits the difference and charges 9% on the small bit while assuming a breach would cost one year, both ends of that file need rebuilding. Escrow's corporate tax accounting work does the bucketing before the return is built: qualifying activities tested first, the always-9% categories cleared out of the ratio, and the de minimis position computed as a working paper with headroom monitored through the year.
