Quick Answer
Capital expenditure buys or improves an asset with lasting value and cannot be deducted in full in the year you spend it. Under Article 28 of Federal Decree-Law No. 47 of 2022, it is recovered gradually through depreciation or amortisation instead. Revenue expenditure keeps the business running day to day and is deducted in full, in the same tax period. Getting it wrong does not just affect your bookkeeping, it changes the Corporate Tax you owe in the year the cost is incurred, because a wrongly expensed capital cost overstates your deduction and understates your tax bill at the 9% rate.

The Classification Test: How to Tell Capital From Revenue
The two categories sound simple until you classify a real invoice. UAE Corporate Tax law gives no fixed checklist, but three tests, applied together, resolve almost every borderline case.
- Duration of benefit. Does the spend produce value lasting beyond the current tax period, an asset still in use in year two, three, or ten, or does it get consumed immediately? A five-year equipment lease payment is revenue. A machine bought outright with a ten-year working life is capital.
- Effect on the asset base. Does the cost create a new asset, enlarge an existing one, or extend its useful life beyond the original? That is capital. Does it simply keep an existing asset in its current working condition? That is revenue.
- Frequency. One-off, structural spending tends to be capital. Recurring costs needed to keep operations going, rent, payroll, utilities, routine servicing, are revenue regardless of the amount involved.
No single test is decisive alone. A recurring cost can still be capital if each instance creates a new asset, a business buying a delivery van every year is still capitalising each van. Where two of the three tests point the same way, that is usually the correct classification.
What the Classification Changes on Your Tax Return
Article 28 sets the general deduction rule: an expense must be incurred wholly and exclusively for the business and must not be capital in nature to qualify for immediate deduction. Once a cost is capital, Article 28 removes it from the current period’s deductible expenses entirely. The depreciation or amortisation charge recognised under IFRS each year becomes the deductible amount instead, spread across the asset’s useful life, subject to any adjustment the law requires. This is not a labelling exercise, it is a timing rule that decides how much of your spend reduces this year’s taxable income versus future years’.
| Criteria | Capital Expenditure | Revenue Expenditure |
|---|---|---|
| What it does | Creates, enlarges, or extends the life of an asset | Maintains day-to-day operations |
| Year-1 deduction under Article 28 | None (capital in nature is excluded) | 100%, in the period incurred |
| How the cost is eventually deducted | Depreciation/amortisation over the useful life | Not applicable, already fully deducted |
| Typical examples | Machinery, buildings, office fit-outs, goodwill on acquisition | Rent, salaries, utilities, routine repairs, marketing |
Worked Example: The Real Cost of Misclassifying a AED 500,000 Item
A business buys manufacturing equipment for AED 500,000 with a 10-year useful life, straight-line depreciation of AED 50,000 a year under IFRS.
- Correct treatment (capital): AED 50,000 deducted in year one. The remaining AED 450,000 is deducted over the following nine years.
- Incorrect treatment (booked as a revenue repair or consumable): The full AED 500,000 is deducted in year one.
- The gap: AED 450,000 of taxable income is understated in year one. At the 9% Corporate Tax rate, that is AED 40,500 of tax the business should have paid in that period and did not, before any late-payment interest or penalty for an inaccurate return is added on top.
The error does not disappear, it reverses. Later years carry no depreciation to claim on an asset already written off, pushing taxable income up in those years instead. Misclassification is rarely a permanent saving, it is an interest-free loan from the FTA that gets called in eventually, with penalty exposure attached if the FTA finds it first during a Corporate Tax audit.
The Repair-vs-Improvement Gray Zone
Most disputes happen here, not with big-ticket asset purchases.
- Revenue (deduct in full): Repainting a building, replacing a broken part with an equivalent, servicing machinery, patching a roof leak. These restore the asset to its previous condition, nothing more.
- Capital (depreciate): Replacing an entire roof with a longer-lasting material, adding a new floor, upgrading machinery with components that increase output or extend its working life. These enhance the asset rather than maintain it.
The test is whether the work restores or improves. “We fixed it” points to revenue. “We made it better or longer-lasting” points to capital.
A Newer Mechanism: Depreciating Fair-Value Investment Property
Businesses holding investment property at fair value under IFRS historically could not claim tax depreciation on it, since no depreciation is recognised in the accounts once an asset is fair-valued instead of held at cost. Ministerial Decision No. 173 of 2025 changed this for tax periods starting on or after 1 January 2025. A taxable person who has elected the realisation basis under Article 20(3) can now claim annual tax depreciation on such property equal to the lower of 4% of its original cost, or its tax written down value at the start of the period.
The election is made in the tax return for the relevant period and is irrevocable. On a later sale or derecognition, the depreciation claimed is added back to taxable income, so the relief is a timing benefit rather than a permanent one, in line with how capital cost recovery works elsewhere in the law.
Frequently Asked Questions
Is the split based on the amount spent?
No. There is no AED threshold that automatically makes a cost capital or revenue. A AED 2,000 tool with a multi-year life used to build up a fixed-asset base is capital in substance, while a AED 200,000 rent payment stays revenue. The nature of the benefit decides the classification, not the size of the invoice.
Can a business choose to expense a capital cost immediately to reduce this year’s tax?
No. Article 28 excludes capital-in-nature expenditure from deduction in the year incurred regardless of preference. Deducting it in full anyway understates taxable income and creates an assessment and penalty risk on review.
Does goodwill on a business acquisition count as capital expenditure?
Yes. Goodwill and other acquired intangibles are capital in nature and are recovered, where allowable, through amortisation rather than an immediate deduction.
What if the accounting treatment of a capitalised cost differs from the required tax treatment?
UAE Corporate Tax generally follows the depreciation or amortisation figure recognised in the IFRS financial statements, subject to any specific adjustment the law requires, such as the fair-value investment property mechanism under Ministerial Decision No. 173 of 2025. Where the two diverge, the return needs a reconciling adjustment, not a re-expensing of the original cost.
How is this different from the general rules on deductible expenses?
The general deductibility rules decide which categories of cost qualify for a deduction at all, covering items such as fines, entertainment, and donations. The capital-versus-revenue test is a separate question that applies first: it decides whether a qualifying cost is deducted now, in full, or spread over several tax periods through depreciation.
