The headline is accurate: trading carbon credits from a UAE free zone can now qualify for the 0% corporate tax rate. But the mechanism by which it qualifies is different from what most summaries describe, and the difference determines whether a given trade is inside or outside the regime.
Two things matter more than the headline. The requirement to trade on a recognised exchange has been removed, replaced by a quoted-price test that can be satisfied through a price reporting agency. And the change is retroactive to 1 June 2023 — meaning positions already filed may need revisiting rather than merely planning forward.
What the decisions are
The operative instruments are Ministerial Decision No. 229 of 2025, issued on 28 August 2025, together with its companion Ministerial Decision No. 230 of 2025. MD 229 repeals and replaces Ministerial Decision No. 265 of 2023, and both apply retroactively from 1 June 2023.
These sit under Federal Decree-Law No. 47 of 2022, the UAE Corporate Tax Law, which established the Qualifying Free Zone Person regime: 0% on qualifying income, 9% on non-qualifying income.
A Cabinet Decision numbered 34 of 2025 is sometimes cited in coverage of this topic. It could not be verified as the operative instrument for these changes in preparing this article; the substantive amendments to Qualifying Activities are carried by MD 229 and MD 230, and those are the references to work from.
The change that matters most: from exchange to quoted price
Under the previous framework, MD 265 of 2023, qualifying commodity trading required the commodity to be in raw form, and the practical reading was that it needed to be traded on a recognised exchange. Both conditions have gone.
MD 229 abolishes the raw-form requirement, which had generated persistent ambiguity about whether basic processing or handling disqualified a commodity. In its place is a market-based pricing test: it is sufficient that a Quoted Price exists for the commodity or a related commodity — either on an exchange or through a recognised price reporting agency, the list of which is set by MD 230.
For environmental commodities this is decisive. A substantial share of carbon credit trading happens over the counter rather than on an exchange. Under a strict exchange-trading test, much of it would sit outside the regime. Under a quoted-price test referencing price reporting agencies, it can qualify.
The practical consequence: the compliance question is no longer “did this trade happen on an approved exchange” but “can I evidence a quoted price from an approved source for this commodity on this date”. That is a documentation exercise, and the absence of such evidence is what now risks disqualification from the 0% rate.
What else falls inside the expanded scope
Carbon credits are one item in a broader expansion. Qualifying Commodities now include, alongside metals, minerals, energy and agricultural commodities:
- Environmental commodities — carbon credits and renewable energy certificates
- Industrial chemicals
- Associated by-products — incidental or secondary products arising from the production or extraction of a qualifying commodity
The activity scope also broadened to cover associated financial derivatives trading used to hedge risks in these activities, and associated structured commodity financing including prepayment and project finance. Treasury and financing activities, previously framed around related parties, now extend to own-account activity.
For a business built around environmental commodities, the practical reading is that hedging and financing structures around the trade can sit inside the regime rather than being pushed out of it.
The conditions that can disqualify you anyway
Qualifying status is not automatic, and three conditions do most of the work in practice.
The 51% revenue test. Commodity trading cannot be claimed as a Qualifying Activity where distribution, warehousing, logistics and inventory management together constitute 51% or more of total revenue in the relevant tax period. A trading operation that has grown a substantial logistics arm can cross that line without any change to its trading business.
Audited financial statements. Under Ministerial Decision No. 84 of 2025, effective for tax periods commencing on or after 1 January 2025, tax groups must file audited special-purpose financial statements regardless of revenue, and standalone entities must maintain audited accounts if revenue exceeds AED 50 million or if claiming QFZP benefits. For anyone relying on the 0% rate, audit is therefore unconditional, not revenue-dependent.
Arm’s-length pricing. All QFZPs must comply with transfer pricing rules under Articles 34 and 35 of the Corporate Tax Law and Ministerial Decision No. 97 of 2023. For intra-group commodity trades, price-reporting-agency data functions as both the benchmarking tool and the compliance burden — the same source that establishes eligibility also establishes whether the internal price was defensible.
A minimum twelve-month holding period applies to securities under the qualifying-activities framework, which is worth checking against any instrument structured as a security rather than a commodity.
The retroactivity point
This is the part most likely to require action rather than reading.
Because MD 229 and MD 230 apply from 1 June 2023 — the inception of the corporate tax law — positions taken under MD 265 were assessed against rules that no longer exist. Professional guidance issued at the time was explicit that businesses should revisit prior positions ahead of the filing deadline, and refile corrected returns where a return had already been submitted.
The direction of the change is mostly favourable — the scope widened and a restrictive test was removed — so revisiting is more likely to identify income that should have been treated as qualifying than the reverse. But that only helps a business that actually looks.
Free Zone and Designated Zone
The distinction persists and is frequently muddled. A Free Zone confers the corporate tax regime discussed here; a Designated Zone is a VAT concept with its own conditions, and distribution from a Designated Zone carries its own qualifying requirements under MD 229.
An entity can be in a Free Zone without being in a Designated Zone. Establishing which status applies, and whether the specific zone hosts the intended activity, is a threshold question before any tax structuring.
What to establish before structuring
- Is a Quoted Price available for the specific instruments traded, from an exchange or an agency on the MD 230 list — and can it be evidenced at trade date?
- What share of revenue comes from distribution, warehousing, logistics and inventory management, against the 51% ceiling?
- Are audited accounts in place, given that claiming QFZP status triggers the requirement regardless of size?
- Have prior-period positions been reviewed against the retroactive rules, and is a corrected return warranted?
- Does the zone itself permit the activity under its own licensing framework, independent of the tax analysis?
Conclusions
The UAE has made environmental commodity trading eligible for the 0% free-zone rate, and it has done so in a way that fits how these markets actually trade. Removing the exchange requirement and the raw-form test, and substituting a quoted-price standard that recognises price reporting agencies, is what makes carbon credits workable within the regime rather than nominally included but practically excluded.
Three things should shape any structuring decision. The eligibility test is evidentiary — a documented quoted price, not a venue. The 51% revenue ceiling and the unconditional audit requirement disqualify more businesses in practice than the activity definition does. And because the rules run retroactively to June 2023, this is a review exercise for existing operations, not only a planning exercise for new ones.
Information purposes only — not tax, legal or investment advice. Free zone corporate tax rules are set by Cabinet and Ministerial Decisions and are subject to amendment and further guidance; confirm current requirements with the Ministry of Finance, the Federal Tax Authority and a qualified UAE tax adviser before structuring. Retroactive application means prior filings may require review.
