Unrealised Gains and the Realisation Basis Election Under UAE Corporate Tax

UAE Corporate Tax is built on the accounts. Article 20(1) determines Taxable Income from standalone financial statements prepared under accounting standards accepted in the State, and Article 20(2) adjusts that accounting income for a defined list of items. Efficient, and mostly uncontroversial — until you notice how much profit modern accounting recognises before any cash moves.

Investment property is remeasured each year. Financial assets are marked to market. Assets are tested for impairment. Foreign currency balances are retranslated at the reporting date. Each of those entries can move accounting profit sharply in a year when nothing was bought, sold or banked.

Why unrealised movements are a tax problem at all

Consider a company holding an investment property carried at fair value. The valuation rises by AED 8 million in a year of no transactions. Accounting profit rises by AED 8 million, and on an unadjusted reading so does taxable income — producing a Corporate Tax liability on a gain the business cannot spend and may never see.

The reverse is just as awkward. A downward revaluation reduces taxable profit in a year the business may have traded perfectly well. Tax then tracks the valuer's opinion rather than the trading result, and the liability becomes as volatile as the property market.

The two versions of the election

Article 20(3) offers two alternatives, and they are not interchangeable.

The first covers all assets and liabilities that are subject to fair value or impairment accounting under the applicable accounting standards. It is the broader sweep: wherever the standards require a remeasurement, the movement is taken out until realisation.

The second covers all assets and liabilities held on capital account at the end of a Tax Period — while still taking into account any unrealised gain or loss on assets and liabilities held on revenue account at the end of that period. In other words, long-term holdings move to a realisation basis and trading items stay on fair value.

The distinction between capital account and revenue account is doing the work in version (b). Broadly, capital account covers long-term holdings — property, plant and equipment, investment property, intangibles and other non-current items — while revenue account covers what the business turns over. Where an asset sits is a question of fact about how it is held, and it deserves a considered answer rather than an assumption.

It is all-or-nothing within the category

Both versions are drafted as "all assets and liabilities". There is no line-by-line choice. A group cannot elect the realisation basis for the property whose value fell and leave the one that rose on fair value. That is the point of the drafting, and it is the first thing to model before electing: run the position across the whole category, in both directions, before deciding.

One Tax Period to decide, and no going back

The Law leaves the conditions to the Minister. Article 8 of Ministerial Decision No. 134 of 2023 supplies them, and the timing is tighter than most coverage lets on.

The decision to elect — or not to elect — is made during the first Tax Period, and it is deemed irrevocable except in exceptional circumstances and with the approval of the Authority. That wording deserves a second reading. Not electing is not a neutral position to be revisited once the numbers are clearer. It is the decision, taken by default, and it binds.

Article 8(2) adds a restriction that is easy to miss. Banks and Insurance Providers preparing accrual financial statements may elect to recognise gains and losses only on a realisation basis in accordance with paragraph (b) of Article 20(3). Version (a) is not open to them. For a bank, the capital-versus-revenue split is not a choice between two elections — it is the only election on offer.

What counts as realisation

Article 9 of the same decision defines the trigger. Realisation includes the sale, disposal, transfer, settlement or complete worthlessness of an asset, and the settlement, assignment, transfer or forgiveness of a liability, in each case as treated under the accounting standards the business applies.

Two transfers are expressly excluded. A transfer between members of the same Qualifying Group under Article 26, and a transfer of an entire business or an independent part of a business under Article 27, are not realisations. Assets can move within a group without crystallising the deferred gain — which matters when a restructuring is being planned around an elected position.

Investment property: a second election sits on top

Ministerial Decision No. 173 of 2025 applies for Tax Periods commencing on or after 1 January 2025, and it is built directly on the realisation basis election. A Taxable Person that has elected the realisation basis may make a further irrevocable election to claim a depreciation deduction on investment property held at fair value. The deduction is the lower of 4% of original cost for each twelve-month Tax Period, or the tax written down value at the start of that period.

The condition is the point. The depreciation election is available only to a person who has already elected the realisation basis under Article 20(3). Without that election it is not available at all. It then applies to every investment property held at fair value rather than a chosen one, and it must be claimed in the tax return for the first Tax Period to which it applies. Miss that return and the right is forfeited.

The deduction is a deferral, not a saving. On realisation, the aggregate depreciation claimed is added back to Taxable Income. It moves tax out of the years the property is held and into the year it leaves.

Not the same thing as the transitional relief

Ministerial Decision No. 120 of 2023 gets mentioned in the same breath and does something different. It runs off Article 20(2)(i) and Article 61, and it excludes the pre-regime share of a gain on immovable property, intangible assets and financial assets owned before the first Tax Period. That election is also made on the first tax return and is also irrevocable.

The dividing line is how the asset is carried. Decision 120 applies where the asset is measured in the financial statements on a historical cost basis. The realisation basis election addresses assets measured at fair value or tested for impairment. An investment property bought in 2019 and carried at cost is a Decision 120 question. The same property carried at fair value is an Article 20(3) question. Settle which one you are in before reaching for either.

Deferred tax does not disappear

Electing the realisation basis changes when a gain enters taxable income, not whether it does. The difference between the carrying amount in the accounts and the amount that will eventually be taxed becomes a temporary difference, and it has to be recognised and tracked. A business that elects and then stops thinking about the revaluation has simply moved the problem into its deferred tax note.

Before you elect

1. Confirm you prepare financial statements on an accrual basis — the election is not available otherwise.
2. Identify your first Tax Period and work back from it. Under Article 8(3) of Decision 134 the choice is made then and is irrevocable, so this is a deadline, not a planning point.
3. List every balance the accounts remeasure: investment property, financial assets, impairment-tested assets, retranslated foreign currency balances.
4. Split them between capital account and revenue account, and record the reasoning. Version (b) depends entirely on that split.
5. Model both versions across the whole category and in both directions, because neither can be applied selectively.
6. If you hold investment property at fair value, model the Decision 173 depreciation election alongside it — and check whether Article 2(5) reopens an election you thought you had lost.
