Investment Property Under UAE Corporate Tax: Two Reliefs, and Your Accounting Policy Already Picked One

A UAE company owns a building. Corporate Tax offers it two quite different reliefs, both real, both worth money, and both easy to lose by inattention. The first spreads a deduction across the years the building is held. The second removes the part of the eventual gain that accrued before Corporate Tax existed at all.

Almost nobody gets to choose between them, because the choice was made when the accounting policy was set.

That is worth settling before anything else, because a great deal of published guidance discusses the two in the same paragraph without saying that they do not overlap.

Route one: fair value, and the 4% depreciation election

Until Decision 173, the fair value model carried a plain disadvantage. A company using the cost model depreciated its building and deducted the charge. A company using the fair value model recognised revaluations instead and deducted nothing, because there was no depreciation in its accounts to deduct. Same asset, same use, different tax outcome on the strength of an accounting policy.

Article 2(1) of Decision 173 closes that gap. A Taxable Person preparing accrual accounts that has elected the realisation basis under Article 20(3) of the Corporate Tax Law may make a further irrevocable election to adjust Taxable Income by a depreciation deduction, set at the lower of:

• 4% of the Original Cost for each twelve-month Tax Period, prorated where the period is shorter or longer, or where the property is held for only part of it
• The Tax Written Down Value at the start of the relevant Tax Period

The realisation basis election is a gate, not a suggestion. Without it there is no depreciation election. Article 2(5) softens that by reopening the door: as an exception to Article 8(3) of Ministerial Decision No. 134 of 2023, a Taxable Person may elect the realisation basis in the very return in which it claims the depreciation — so a business that let the first Tax Period pass without electing is not automatically shut out.

Land is not Investment Property

Decision 173 defines Investment Property by reference to International Accounting Standard No. 40 — a building, or part of a building, held to earn rental income or for capital appreciation or both — and then says in terms that it does not include land, along with the exclusions IAS 40 itself carries.

For a UAE portfolio that matters more than it might elsewhere. Where a freehold sits on the balance sheet as a single fair-valued figure covering land and building together, only the building element supports the deduction, and the split has to be capable of being evidenced. A land-heavy holding gets considerably less from this election than the headline 4% implies.

The clock started when you bought it

This is the detail most likely to produce a wrong number. The deduction is capped at the Tax Written Down Value, and that value runs off the Opening Value rather than off cost. Decision 173 defines the Opening Value as the Original Cost reduced by an aggregate depreciation deduction of 4% for each Gregorian calendar year — prorated for part years — during which the Taxable Person held the property before the relevant Tax Period.

So the 4% is treated as having been running the whole time the building was owned, whether or not any deduction was ever claimed. A property acquired in 2015 arrives at the first Tax Period under this Decision already notionally written down by roughly four tenths of its Original Cost. The election does not restart the clock; it lets you claim what is left on it.

Elect on time, or lose it

Article 3 sets three timelines. A Taxable Person holding Investment Property during the first Tax Period to which the Decision applies elects in that return. One that does not yet hold any elects in the return for the period in which it first holds one. One that had elected Small Business Relief under Article 21 elects in the return for the first Tax Period in which Article 21 no longer applies.

Article 3(4) then disposes of the question of what happens if you miss it: the Taxable Person is considered to have forfeited the right to make the election. Not deferred, not available on application — forfeited. And under Article 2(4), once made the election covers all of the Taxable Person's Investment Properties held at fair value, so there is no partial version to fall back on.

Four ways the deduction is clawed back

The deduction is a deferral. Article 4(2) increases Taxable Income by the aggregate depreciation claimed on realisation, prorated for a partial realisation. What counts as realisation is wider than a sale. Article 4(1) lists, whichever comes earlier:

• Sale, disposal, transfer, settlement, complete worthlessness or other derecognition under the accounting standards
• A change of accounting policy on that property from the fair value model to the cost model
• The Taxable Person becoming an Exempt Person, or electing for Article 21 to apply
• The Taxable Person ceasing its Business or Business Activity, by dissolution, liquidation or otherwise

Transfers within a Tax Group and transfers under Articles 26 and 27 are carved out of the clawback, but they do not make the deduction disappear. Article 5 requires the transferee using the cost model to strip out depreciation to the extent of what the transferor claimed, and to bring the excluded amount back in when the property is eventually realised. The deferred amount travels with the asset.

Article 6 adds a specific anti-abuse rule. Where Investment Property is transferred between Related Parties, the Authority may at its discretion disallow the transferee's depreciation deduction if the arrangement lacks a valid commercial or other non-fiscal reason reflecting economic reality.

Route two: historical cost, and the transitional relief

Decision 120 answers a different question. Corporate Tax began on 1 June 2023, but a building bought in 2016 had been rising in value for seven years before that. Article 61(1) of the Corporate Tax Law sets the opening balance sheet as the closing balance sheet of the year before the first Tax Period, and Decision 120 lets a Taxable Person exclude the part of an eventual gain that belongs to the pre-regime period.

Article 2(1) sets three conditions, all of which must hold. The property is owned before the first Tax Period. It is measured in the financial statements on a historical cost basis. And it is disposed of, or deemed disposed of, during or after the first Tax Period for a value exceeding its net book value.

There are then two ways to compute the excluded amount.

The valuation method needs an official valuation and rewards a property that appreciated sharply before 2023. Time apportionment needs no valuation at all and simply splits the gain by elapsed time, which suits a steadier asset or a smaller one where a formal valuation is not worth commissioning.

Property is per-asset, intangibles are not

Article 2(5) makes the immovable property election in respect of each Qualifying Immovable Property, on the first Tax Return, irrevocable except in exceptional circumstances with the Authority's approval. So the choice is made building by building, and a portfolio can mix methods across properties.

Intangible assets work differently, and the difference is easy to miss because the two sit in adjacent articles. Article 3(4) makes that election once, applying to all Qualifying Intangible Assets. And Article 3(5) caps the pre-first-Tax-Period ownership days at the equivalent of ten years, except in exceptional circumstances with approval. Immovable property carries no such cap — a building held since 2005 counts every one of those days.

CTP009: what changed for real estate developers

On 26 September 2025 the FTA issued Corporate Tax Public Clarification CTP009 on the application of the valuation method to Qualifying Immovable Property disposed of by a real estate developer. It covers the valuation method only, and it settles several questions that Decision 120 alone leaves open.

The most consequential is what counts as a disposal. CTP009 states that disposal and deemed disposal follow the principles of the accounting standards the Taxable Person applies — so where a developer recognises revenue as a performance obligation is satisfied under IFRS 15, on a percentage-of-completion basis, that recognition is itself treated as a disposal or deemed disposal.

Developers with projects already under way at the start of the first Tax Period are therefore inside the transitional rules through their ordinary revenue recognition, without a sale contract completing in the period at all.

• The Qualifying Immovable Property is either the entire project or specific units within it, based on how the project is recognised in the accounts — the adjustment follows the basis on which accounting profits are realised.
• Classification under IFRS or IFRS for SMEs as a fixed asset or as inventory does not affect whether the transitional adjustment applies.
• Market Value is determined by the relevant government competent authority in the UAE, including accredited valuers that authority specifies — not by an internal or freely chosen valuation.
• Market Value must relate to the Qualifying Immovable Property alone. Where it does not, it is adjusted — stripping out any part of the project the developer retains an interest in, and any part already disposed of before the first Tax Period.
• Original cost and net book value are the project cost recognised in the opening balance sheet: capitalised cost less whatever had already gone through the income statement before the first Tax Period.

The practical effect is that a developer cannot compute this from a single project-level number. Market Value, original cost and net book value must each be pinned to the same defined element of the same project, and the retained and already-sold portions have to come out of all three consistently.

The two routes side by side

What to check now

1. Confirm the measurement basis for each property in the accounts. That single fact decides which relief is even on the table, and it is a matter of record rather than of choice at this point.
2. For fair-valued property, confirm whether the realisation basis was elected — including by default. If it was not, Article 2(5) of Decision 173 is the route back in, and it runs through the same return as the depreciation election.
3. Separate land from buildings in the fair value figure, with evidence. Only the building element supports the deduction.
4. Build the Opening Value calculation from the acquisition date, not from the first Tax Period. Count the calendar years of prior ownership and apply the 4% reduction before anything else.
5. Check the Article 3 election deadline against your actual Tax Period. Forfeiture is the stated consequence, and it is not curable.
6. Before electing Small Business Relief, quantify the Article 4(1)(c) clawback and remember Article 4(4) puts it in the preceding Tax Period.
7. For property carried at cost, obtain the government valuation early if the valuation method is likely to give the better answer. Time apportionment needs no valuation and may be sufficient.
8. Developers: identify every project where IFRS 15 revenue was recognised at or after the start of the first Tax Period, and fix the Qualifying Immovable Property element before valuing anything.
