Is a gain on revaluation of property taxed under Corporate Tax?
Yes, a revaluation gain is normally taxable as it arises - but you can avoid taxing the unrealised part by electing to be taxed only when the property is actually sold, and if you owned the property before your first tax year, you can also exclude the gain that built up before Corporate Tax started.

The detail
Under Article 20(2) of the Corporate Tax Law, Taxable Income starts from Accounting Income, which includes fair-value revaluation gains, so an unrealised gain is taxable unless the Taxable Person has elected the realisation basis under Article 20(3), in which case unrealised fair-value gains and losses are excluded until actually realised. Separately, where the property was owned before the Taxable Person's first Tax Period and is carried at historical cost, Ministerial Decision No. 120 of 2023 lets the Taxable Person exclude the portion of the gain on eventual disposal that accrued before the first Tax Period. A further election under Ministerial Decision No. 173 of 2025 allows a notional depreciation deduction for investment property held at fair value where the realisation-basis election has been made.123
What the law says
- Taxable Income is Accounting Income adjusted as specified, so fair value gains are taxable unless an exception applies.2
- A Taxable Person on accrual accounting may irrevocably elect to recognise gains and losses on fair-valued or capital-account assets only on realisation, excluding unrealised gains from Taxable Income.2
- For immovable property owned before the first Tax Period and held at historical cost, a Taxable Person may elect to exclude from the taxable gain the portion that accrued before the first Tax Period, calculated under Ministerial Decision No. 120 of 2023.1
What it depends on
- The realisation-basis election must be made in the first Tax Period and is irrevocable (or treated as irrevocably declined if not made then), per FTA guidance.4 Based on FTA guidance
- The Ministerial Decision No. 120 of 2023 exclusion only applies to property owned before the first Tax Period, measured at historical cost, and disposed of during or after the first Tax Period.1
- The depreciation election under Ministerial Decision No. 173 of 2025 is only available if the realisation-basis election has already been made and applies to all fair-valued investment properties.3
Check before you rely on it
- Confirm whether the property is measured at fair value or historical cost in your Financial Statements.
- Check whether a realisation-basis election was made (or deemed declined) in your first Tax Period.
- If the property was owned before your first Tax Period, check whether the Article 2 exclusion election was made with your first Tax Return.

The decision to make, or not make, an election to apply the realisation basis must be made by the Taxable Person during their first Tax Period, and will be deemed irrevocable except under exceptional circumstances and pursuant to approval by the FTA.134 If the Taxable Person does not make the election to apply the realisation basis in their first Tax Period then this will be considered an irrevocable election in itself. Example 7: Fair value gain on land During the Financial Year ending 31 December 2025, C LLC, a UAE resident company, recognised a revaluation gain in its Financial Statements of AED 10,000,000 in respect of some land which is measured at fair value. The original cost of the land was AED 50,000,000 and following the revaluation the net book value of the land is AED 60,000,000. The land was not sold at the end of the Tax Period and, therefore, the revaluation gain is considered ‘unrealised’. If no election is made, C LLC would be subject to tax on the unrealised gain of AED 10,000,000 in relation to the Tax Period ending on 31 December 2025. However, if C LLC elects to apply the realisation basis in respect of all assets and liabilities that are subject to fair value or impairment accounting, then the company would not have to include the revaluation gain of AED 10,000,000 when calculating their Taxable Income for this Tax Period. Example 8: Loss below original cost During the Financial Year ending 31 December 2025, S LLC, a UAE resident company, recognised a revaluation loss in its Financial Statements in respect of an asset measured at fair value. The original cost of the asset was AED 250,000, and following the revaluation the net book value of the asset is AED 200,000. The asset has not been sold at the end of the Tax Period. The revaluation loss of AED 50,000 is considered ‘unrealised’. Exempt Income Several exemptions are provided for within the Corporate Tax regime.135 The purpose of these exemptions is to either: • exempt income and capital gains arising from the activity of another juridical person or a foreign branch on the basis that it has already been taxed; or 134 Article 8(3) of Ministerial Decision No. 134 of 2023. 135 Articles 22 to 25 of the Corporate Tax Law.
