UAE Investment Property Tax Depreciation 2026: Who Should Consider the 4% Rule Before Filing?
UAE businesses that hold investment properties at fair value now have a potentially valuable Corporate Tax election to review before filing their applicable tax return. Under Ministerial Decision No. 173 of 2025, an eligible Taxable Person can claim tax depreciation on qualifying investment property held at fair value, provided the required realisation-basis election and other conditions are satisfied.
The annual deduction is generally the lower of 4% of the property’s Original Cost or its remaining Tax Written Down Value at the beginning of the relevant Tax Period. But this is not a blanket 4% deduction for every Dubai landlord, every property investor or the full purchase price of every building.
It is a specific Corporate Tax mechanism for qualifying taxpayers using fair-value accounting for investment property. Land is excluded, the election is irrevocable, historical ownership can reduce the available tax base, and depreciation previously claimed generally comes back into taxable income when a realisation event occurs.
Most important deadline point: 30 September 2026 is critical for Taxable Persons whose financial year ended on 31 December 2025. If that return is also the taxpayer’s first applicable return in which the MD 173 election must be made, failing to make the election within the prescribed timeline can forfeit the right to elect. The September date is not a universal deadline for every UAE property owner.
For investors looking for a broader overview of taxation around property ownership, Aurantius has separately covered Dubai property taxes and investor obligations. This article focuses specifically on MD 173 and the fair-value depreciation election.
Why Ministerial Decision 173 Was Introduced
The issue starts with how investment property can be measured under IAS 40.
A taxpayer applying a cost-based accounting model can generally recognise accounting depreciation on a depreciable building. Subject to the Corporate Tax rules, that accounting expense can affect taxable income.
Under the IAS 40 fair-value model, however, an investment property is remeasured to fair value and depreciation is not recorded in the same way. That created a potential tax mismatch: economically similar investment properties could receive different depreciation treatment simply because different accounting measurement models were being used.
The Ministry of Finance states that MD 173 was introduced to create greater tax neutrality between investment property held at historical cost and investment property carried at fair value.
Who Can Use the 4% Investment Property Depreciation Rule?
The rule is narrower than the phrase “4% property depreciation” suggests.
Under the official decision, a Taxable Person must prepare Financial Statements on an Accrual Basis of Accounting and must have elected to take relevant gains and losses into account on a realisation basis under Article 20(3) of the UAE Corporate Tax Law.
The property must also meet the decision’s definition of an Investment Property and be held at fair value under the applicable Accounting Standards.
| Condition | Why It Matters |
|---|---|
| Taxable Person | This is a UAE Corporate Tax mechanism, not an automatic deduction available to every individual property owner. |
| Accrual accounting | Required by MD 173 for the election. |
| Fair-value investment property | The rule addresses investment properties for which fair-value accounting otherwise produces no accounting depreciation. |
| Realisation basis | The taxpayer must make the relevant Article 20(3) election. |
| Timely MD 173 election | The depreciation election is irrevocable and must be made within the prescribed Tax Return timeline. |
The 4% Calculation: It Is Not Simply 4% of Today’s Property Value
MD 173 does not allow a taxpayer to take 4% of the property’s current market value every year.
For each 12-month Tax Period, the depreciation deduction is the lower of:
4% × Original Cost
OR
Tax Written Down Value at the start of the Tax Period
The deduction is prorated where the Tax Period is shorter or longer than 12 months or where the Investment Property is held for only part of the period.
The decision defines Original Cost by reference to IAS 40 and also includes qualifying subsequent capitalised costs, subject to the arm’s-length principle.
Land Is Excluded From the MD 173 Investment Property Definition
This is one of the most important points for property-holding businesses.
For the purposes of MD 173, Investment Property is defined as a building or part of a building held to earn rental income, for capital appreciation or both, consistent with IAS 40. The decision expressly states that Investment Property does not include land.
A company that purchased a building together with the underlying land therefore cannot simply apply 4% to the entire acquisition price without examining the allocation.
Businesses should maintain defensible records supporting the building component of Original Cost. Where the historical acquisition documentation does not provide a reliable allocation, professional valuation and tax advice may be needed before filing.
Older Properties May Have Much Less Depreciation Available
One of the easiest mistakes is assuming that every qualifying building starts with a fresh 25-year depreciation life in 2025.
It does not.
MD 173 contains an Opening Value mechanism that reduces Original Cost by 4% for each relevant Gregorian calendar year, or part thereof, during which the property was held before the applicable Tax Period.
This can materially reduce the available Tax Written Down Value for properties owned for many years before the new decision applied.
Illustrative Example
Assume a qualifying property company owns a building with an Original Cost attributable to the qualifying building of AED10 million. For illustration, assume five relevant years of historical ownership are taken into account before its first applicable MD 173 Tax Period.
| Original qualifying building cost | AED10,000,000 |
| 4% annual notional reduction | AED400,000 |
| Five-year historical reduction | AED2,000,000 |
| Illustrative Opening Value | AED8,000,000 |
| Potential annual deduction | AED400,000, subject to the rules |
Illustration only: The applicable Opening Value calculation depends on the taxpayer’s facts, acquisition history, applicable Tax Period and the detailed rules in MD 173. This example is not a tax computation for a specific business.
The 4% Deduction Is Mainly a Timing Benefit, Not Free Tax Savings
The annual deduction can reduce taxable income during the holding period, but MD 173 contains a recapture mechanism.
When a relevant realisation event occurs, the aggregate depreciation deduction previously claimed is generally added back to Taxable Income, except where specified tax-neutral transfer provisions apply, including certain transfers under Articles 26 and 27 of the Corporate Tax Law or between members of a Tax Group.
Realisation can include more than a straightforward sale. The decision also identifies events such as derecognition of the property, changing the accounting policy from fair value to cost, becoming an Exempt Person, electing for Small Business Relief, or ceasing the relevant Business or Business Activity.
Think of MD 173 as cash-flow timing: The deduction may defer Corporate Tax during the holding period, but the amount claimed can be recaptured later. The economic value therefore depends on holding period, financing, expected exit timing, future taxable income and the taxpayer’s wider tax profile.
This is particularly important when investors assess property returns. Aurantius’ Dubai real estate ROI guide explains why investment returns should be assessed after recurring ownership costs rather than relying on gross yield alone. Corporate Tax can add another layer for business-owned portfolios.
Is 30 September 2026 Really the Deadline?
For many calendar-year businesses, yes. For every taxpayer, no.
The Federal Tax Authority confirmed in September 2026 that Taxable Persons whose financial year ended on 31 December 2025 must file their Corporate Tax Return and pay Corporate Tax due by 30 September 2026.
MD 173 separately states that a taxpayer already holding Investment Property during its first applicable Tax Period must make the depreciation election in the Tax Return for that period.
If no Investment Property is held during that first applicable period, the election is made in the Tax Return for the Tax Period in which the first Investment Property is held. Different rules also apply where Article 21 Small Business Relief was previously elected.
Accordingly, the correct compliance question is not simply “Is September 30 the deadline?” It is:
Is the Tax Return due on 30 September 2026 my first applicable return in which MD 173 requires me to make the election?
For a calendar-year taxpayer answering yes, this is a significant deadline because Article 3 of MD 173 states that failure to elect within the prescribed timeline means the taxpayer is considered to have forfeited the right to make the election.
The Election Is Irrevocable and Portfolio-Wide
The MD 173 election is not designed as an annual choice where a taxpayer claims depreciation when convenient and skips it when inconvenient.
The election is irrevocable. Professional guidance from KPMG and FTI also highlights that the election applies across qualifying investment properties rather than allowing taxpayers to cherry-pick individual buildings.
This makes portfolio modelling important. A business may own:
• mature properties with little remaining TWDV;
• recently acquired properties with a large available tax base;
• assets likely to be sold soon;
• assets intended to remain in the portfolio for decades; and
• properties that could later move within a group restructuring.
The immediate deduction may therefore look attractive for one asset while the portfolio-wide tax consequences are more complicated.
What Happens if a Calendar-Year Taxpayer Misses 30 September 2026?
There are two separate risks to distinguish.
Risk 1: Losing the MD 173 Election
Where the return is the taxpayer’s required election return under Article 3 of MD 173, failing to make the election within the applicable timeline can mean forfeiting the right to make it later.
Risk 2: Corporate Tax Filing and Payment Penalties
Separately, the UAE’s Corporate Tax administrative-penalty schedule provides for a late Tax Return penalty of:
• AED500 for each month or part of a month for the first 12 months; and
• AED1,000 for each month or part of a month from the 13th month onwards.
Failure to settle Corporate Tax Payable is also subject to a monthly penalty calculated at an annual rate of 14% on the unsettled amount under the applicable Cabinet Decision.
Taxpayers approaching a filing deadline should therefore not postpone the MD 173 review until the final days of the return-preparation process.
A Practical MD 173 Review for Property-Holding Businesses
1. Identify the accounting model.
Confirm which investment properties are measured at fair value under IAS 40.
2. Confirm Corporate Tax eligibility.
Determine whether the taxpayer satisfies the accrual-accounting and realisation-basis conditions.
3. Separate land from qualifying building cost.
Land is expressly excluded from the MD 173 definition of Investment Property.
4. Reconstruct Original Cost.
Include relevant qualifying capitalised expenditure and maintain supporting documentation.
5. Calculate Opening Value and TWDV.
Historical ownership can materially reduce the depreciation remaining.
6. Model the recapture.
Compare the short-term tax deferral with expected disposal dates and future taxable income.
7. Review the whole portfolio.
The election is not a property-by-property annual optimisation tool.
8. Confirm the correct filing deadline.
Do not assume 30 September applies unless the relevant Tax Period ended on 31 December 2025 or the taxpayer otherwise has that filing date.
Does the 4% Rule Make Corporate Property Ownership More Attractive?
Potentially, but tax depreciation should not be the primary reason to acquire a property.
The value of the election depends on the taxable person’s structure, the building’s Original Cost, historical holding period, financing, rental income, operating expenses and expected disposal strategy.
A tax deduction can improve holding-period cash flow, but it cannot rescue an overpriced asset, weak rental demand or excessive service charges.

FAQ: UAE Investment Property Depreciation Under MD 173
Question: Does every UAE property investor get a 4% Corporate Tax depreciation deduction?
Answer: No. MD 173 applies to qualifying Taxable Persons holding Investment Property at fair value and satisfying the decision’s accounting, realisation-basis and election requirements. It is not a general personal-property tax allowance.
Question: Is the depreciation calculated on current market value?
Answer: No. The annual deduction is the lower of 4% of Original Cost or the Tax Written Down Value at the beginning of the Tax Period, subject to the detailed rules.
Question: Can land be depreciated under MD 173?
Answer: No. The decision expressly excludes land from its definition of Investment Property.
Question: Is the MD 173 depreciation election reversible?
Answer: No. The decision describes the election as irrevocable, which is why businesses should model its portfolio-wide consequences before filing.
Question: Is 30 September 2026 the MD 173 deadline for every company?
Answer: No. It is the Corporate Tax filing and payment deadline for taxpayers whose financial year ended on 31 December 2025. It becomes the critical MD 173 election date where that return is also the taxpayer’s first applicable return in which the election must be made.
Question: Do I permanently save tax by claiming the 4% deduction?
Answer: Generally, the rule creates a timing benefit rather than permanent tax elimination because aggregate depreciation claimed is normally added back when a realisation event occurs, subject to specified reliefs and transfer rules.
Question: What happens if the property was owned for many years before 2025?
Answer: MD 173’s Opening Value mechanism can reduce Original Cost by 4% for relevant historical years of ownership. Older properties may therefore have significantly less TWDV remaining, and very old assets may have little or no further depreciation available.
Conclusion: Treat MD 173 as a Portfolio Tax Decision, Not a Simple 4% Deduction
Ministerial Decision No. 173 of 2025 gives qualifying UAE businesses an important solution to the depreciation mismatch created when investment property is measured at fair value under IAS 40.
The opportunity is straightforward: qualifying taxpayers can potentially reduce taxable income during the holding period using a tax depreciation deduction based on the lower of 4% of Original Cost or remaining TWDV.
The decision becomes more complex once historical ownership, land allocation, the realisation-basis election, portfolio-wide application and future recapture are considered.
For calendar-year businesses with a 31 December 2025 year-end, the immediate issue is timing. The FTA has confirmed that the Corporate Tax Return and any tax payable are due by 30 September 2026. Where that return is also the first applicable MD 173 election return, the business should complete its analysis before filing rather than assuming the election can be added later.
Businesses that may benefit most are those holding qualifying fair-value investment properties for meaningful periods and capable of supporting Original Cost, land/building allocation and TWDV calculations with robust records.
Businesses planning near-term disposals, restructurings or significant portfolio changes should be particularly careful because the eventual recapture can materially change the apparent benefit.
The 2026 property-company rule: Do not ask only, “How much can we deduct this year?” Ask how the irrevocable election affects the entire property portfolio through acquisition, holding, restructuring and eventual disposal.
Aurantius Real Estate provides Dubai property-market analysis for investors evaluating acquisition costs, yield, location and long-term property strategy. Corporate Tax elections, IAS 40 treatment and MD 173 calculations should be reviewed with a qualified UAE tax adviser or accountant using the taxpayer’s actual financial statements and ownership history before the applicable return is filed.
