Getting taxed on a gain you haven't banked

Your investment property gets revalued upward at year-end and, on paper, you just made a few million. You have not sold anything. No cash has moved. But under the default rules, that unrealised fair-value gain can flow straight into your taxable income and land you a real corporate tax bill on money you have not seen. The fix is the realisation basis election under Article 20(3) of Federal Decree-Law No. 47 of 2022, with the mechanics set out in Ministerial Decision No. 134 of 2023 on the general rules for determining taxable income. Elect it, and gains and losses count only when an asset is actually sold, settled or disposed of. If you would rather not handle this in house, this is what our taxable income calculation covers.

This is one of the quietest but most useful choices in the UAE corporate tax regime, and you make it early. Get it right and you match your tax bill to your cash flow. Get it wrong and you either pay tax on paper profits or lock yourself out of a deduction you wanted. Here is how it works, and how we decide.

The default: fair-value swings hit your tax bill

UAE corporate tax starts from your accounting profit. If you keep your books under IFRS and carry certain assets at fair value, investment property under IAS 40, some financial instruments, biological assets, then every revaluation moves your profit and loss. A markup becomes taxable income. An impairment becomes a deduction. All of it before a single dirham changes hands. For an asset-holding business, that means your tax can swing with a valuer’s opinion rather than with anything you actually earned.

What Article 20(3) actually lets you do

Article 20(3) of the Corporate Tax Law gives you an out. Elect the realisation basis and you strip unrealised gains and losses out of taxable income until the asset or liability is realised. Sell the property, settle the instrument, dispose of the asset. That is when the gain or loss counts for tax. Two things to know before you get excited. The election is made in your first tax period, and it is treated as irrevocable except in exceptional circumstances with the FTA’s approval. So this is not a knob you turn each year. It is a stance you take up front and live with.

Two scopes, and they are not the same choice

Ministerial Decision No. 134 of 2023 gives you two versions of the election, and people mix them up. Scope one covers only assets and liabilities held on the capital account at the end of the tax period, broadly the things you hold for long-term investment rather than to trade. Scope two is wider: all assets and liabilities that are subject to fair-value or impairment accounting under your accounting standards. Which you pick changes what stays out of tax until realisation. One more thing: banks and insurance providers sit under their own treatment here, so the standard framing does not map cleanly onto them.

Worked example: a paper gain and a real tax bill

Take a Business Bay property investment company. It holds one commercial unit as investment property under IAS 40, carried at fair value. At the start of the period the valuation is AED 20,000,000. At year-end the valuer marks it to AED 24,500,000, an unrealised gain of AED 4,500,000. Nothing was sold. Without the election, that AED 4,500,000 flows into accounting profit and is taxable, costing roughly AED 405,000 at the 9% rate (the first AED 375,000 of taxable income sits at 0%). With the Article 20(3) election, that gain is deferred: the tax on it this period is nil. When the company eventually sells (say in 2030 for AED 26,000,000), the realised gain is taxed then, when the cash arrives. Same economics, very different timing.

When electing makes sense (and when it doesn't)

The trade-off is honest and worth saying out loud: the realisation basis cuts both ways. It shelters your paper gains, but it also parks your paper losses. If you are sitting on assets you expect to write down, keeping the default treatment lets you take those impairments against tax sooner. This is the mistake we see most, a business elects to defer gains and forgets it just deferred its losses too.

The link to the investment-property depreciation election

There is a second reason this election matters more from 2025 onward. Ministerial Decision No. 173 of 2025 lets businesses claim a depreciation deduction on investment property held at fair value, capped at 4% of the original cost per year. Useful. But it is only available to a business that has elected the realisation basis under Article 20(3). No realisation basis election, no depreciation election. So the two decisions are joined: if the 4% deduction is part of your plan, the realisation basis is the door you have to walk through first. We cover that deduction in detail in our investment-property depreciation guide.

So where does this leave you? If you hold fair-valued assets, the realisation basis is often the difference between a tax bill that tracks your cash and one that tracks a valuer’s spreadsheet. Just decide it early, in the first period, with the loss side and the MD 173/2025 depreciation link fully in view.
