Crypto and the Corporate Tax realisation election: decide before your first return

For a company that holds, trades or mines crypto, one decision in its first Corporate Tax return affects the tax on every price movement that follows: whether gains and losses are taken into account as they appear in the accounts, or only when they are realised. The choice is made once, at the start, and generally cannot be undone — so it is worth understanding before the first return is filed, not after.

What the election does

Taxable income normally follows the accounting profit. If the financial statements recognise an impairment loss or a fair value gain on crypto, that movement flows into taxable income for the same year — even though nothing has been sold.

A company can instead elect to take gains and losses into account on a realisation basis. Unrealised gains are then not taxable, and unrealised losses are not deductible, until they are realised — for an asset, on its sale, disposal, transfer, settlement or complete worthlessness. A token-to-token swap is generally a disposal of the first token, so a gain or loss on a swap is generally realised even with the election in place.

The election takes one of two forms. It is not made asset by asset:

Because it covers every qualifying asset and liability, the election also reaches the company's other investments, not only its crypto.

Why the first return matters

• The election must be made during the first tax period — in practice, in the first Corporate Tax return.
• It is irrevocable, except in exceptional circumstances and with the FTA's approval, decided case by case.
• A company that misses it in the first return cannot simply choose it later when prices move.

So the decision has to be modelled before that return is filed — ideally before the year end, because the closing valuations are what decide its effect.

How the accounting treatment changes the effect

The classification itself is an accounting judgement about how the crypto is used — investment, trading stock or client assets — set out in the accounting policy. See accounting for crypto under IFRS.

Mining: the reward, and what comes after

No IFRS standard deals directly with mining rewards. Companies set a policy — commonly, income at fair value when the company obtains control of the coins — and disclose it as a significant judgement.

In our view, the election does not defer that mining income itself: it is income from the company's activity, recognised when the coins are received, not a change in the value of an asset already held. What the election does affect is what happens next — the impairment or fair value movements on mined coins while the company holds them, until they are sold or swapped. A miner that holds its coins through volatile years therefore feels the election most.

Closing balances and valuation: the inputs that decide the answer

• Quantities — every wallet and exchange account reconciled to the ledger at the year end.
• Price source and cut-off — a written rule, for example the price at 23:59 UAE time on the reporting date from the principal market, applied the same way every year.
• Currency — US dollar prices converted to AED at a recorded rate; the dirham is pegged at AED 3.6725 to the dollar.
• Impairment testing — at least annually for crypto treated as having an indefinite life, with the evidence kept.
• Two records — under the election, the tax value of each holding is tracked separately from its accounting carrying amount for every later year.

Weak closing valuations produce a wrong return with or without the election — and make it impossible to model the choice properly.

A simple example: timing, not total

A company holds crypto under the cost model. It cost AED 400,000; at the first year end it is worth AED 300,000; at the second it has recovered to AED 450,000; in the third year it is sold for AED 450,000.

The total is the same, but the timing is not — and timing has real consequences. The 0% band on the first AED 375,000 of taxable income applies to each tax period separately, and losses carried forward can offset only 75% of a later year's taxable income. A deduction in the wrong year can be worth much less than the same deduction in another.

Factors to weigh before the first return

• How the company uses its crypto — investment, trading or mining — and how long it expects to hold.
• Which form would apply, and whether trading stock would still be taxed on fair value.
• The other assets and liabilities the election would also cover.
• Whether the income is taxed at 9%, or may qualify for 0% under the free zone rules — see the 0% conditions.
• Expected profits and losses in the early years, and the effect of the 75% limit on loss relief.
• Whether the records can track tax values separately from accounting values every year.

There is no answer that suits every company: it turns on the company's own holdings, accounting policy and figures. The sound approach is to model both routes on the actual closing balances before the first return is filed.

We build the closing valuations and model both routes for crypto-holding and mining companies before their first return. See crypto accounting and tax and crypto and UAE tax, or talk to us.
