UNDERSTANDING DEFERRED TAXES: PART II

This article builds on Part I [see Part I - Understanding Deferred Taxes], which covered the fundamentals: what deferred tax assets (DTAs) and deferred tax liabilities (DTLs) are, how temporary differences arise, and how the key GCC jurisdictions differ in their corporate tax rules. Part II moves into the more judgement-heavy territory: when a DTA can actually be recognised, the important exceptions to the normal recognition rules, and how these play out in specific transactions - leases, decommissioning obligations, business combinations, group structures and Pillar Two. 

1. Four questions every deferred tax conclusion must answer 

Deferred tax analysis can feel sprawling, but in practice every defensible conclusion rests on the same four building blocks - worked through in sequence: 

A. Tax base analysis - establish what each asset and liability is actually worth for tax purposes, and why. This was covered in detail in Part I, including how to identify the tax base of both assets and liabilities and how temporary differences arise from the gap between book and tax values. Get this wrong and everything that follows will be wrong too. 

B. Reversal schedule - map out when each temporary difference will reverse, and what type of income or deduction it will produce when it does. Timing and character (ordinary income vs. capital, restricted basket vs. unrestricted) both affect whether a DTA is actually usable. 

C. Taxable profit evidence - Identify the sources of future taxable profit that will be available when each deductible difference reverses. But watch out for two things. First, check whether the reversal itself will generate a real tax saving or simply deepen a loss - if the year in which a deductible difference reverses is already a loss-making year, the deduction does not crystallise a tax benefit, it just makes the loss bigger, and that bigger loss then needs its own probability assessment before a DTA can be recognised on it. Second, where prior year losses are being carried forward, remember that any deductible temporary differences reversing in the same year reduces taxable profit first - which may leave little or no profit against which those carried-forward losses can be offset. Evidence that does not survive this stress test cannot support a DTA. 

D. Presentation mapping - determine where the deferred tax charge or credit belongs: profit or loss, other comprehensive income, or directly in equity. The answer follows the underlying transaction - not a default assumption that everything goes through P&L. 

Each of the sections that follow works through one or more of the building blocks outlined in Paras B, C or D above. 

2. DTA recognition: the probable future taxable profit test 

IAS 12 requires a DTA to be recognised for deductible temporary differences only to the extent that it is probable that taxable profit will be available against which the deductible difference can be utilised. The same test applies to DTAs from unused tax losses and unused tax credits. 

A rigorous DTA assessment answers three questions in sequence: 

• What is the deductible item, and what is its tax character? Is it an ordinary deductible item, or is it restricted to a particular 'basket' (for example, capital losses that can only be set against capital gains)? IAS 12 requires assessment by the same taxable entity and the same taxation authority - you cannot net positions across different jurisdictions or unrelated entities. 
• What source of taxable profit supports recovery? IAS 12 identifies three: (a) future reversal of existing taxable temporary differences, (b) forecast taxable profit, and (c) tax planning opportunities.  
• What constraints limit utilisation? Any constraint that limits how much of a loss or deductible difference can actually be used - such as expiry windows, annual utilisation caps, or restrictions that confine certain deductions to a specific type of income - must be reflected in the amount of DTA recognised. It is not sufficient to note the constraint in a footnote and recognise the full amount anyway.

2.1  The 'recent losses' threshold: why the bar is higher

IAS 12 notes that a history of unused tax losses is strong evidence that future taxable profits may not be available. When an entity has such a history, a DTA may be recognised only to the extent it has sufficient taxable temporary differences that will reverse in the right period, or there is convincing other evidence - a higher threshold than the standard 'probable' test. IAS 12 also requires specific disclosure of the DTA amount and the nature of the supporting evidence in those circumstances. 

In practice, convincing other evidence means concrete, verifiable items: signed contracts with identified counterparties, firm order backlogs, executed restructuring plans with documented cost savings, or tax planning actions that management would take regardless of the DTA question. Optimistic business-plan projections alone rarely meet the bar. 

2.2  Expiry periods and annual utilisation caps 

IAS 12 requires you to consider whether taxable profits will exist before expiry of the losses, and whether utilisation is restricted by tax law. This is not merely a timing check - when tax law caps annual utilisation (for example, losses may only shelter a specified percentage of taxable profit each year), the recognised DTA must be restricted accordingly, even where reversing taxable temporary differences might otherwise appear to support recognition.

2.3 Tax planning opportunities: what counts and what does not

IAS 12 describes tax planning opportunities as actions the entity would take to create or increase taxable income before expiry of the losses. Examples include deferring certain deductions or selling (and possibly leasing back) appreciated assets. Two guardrails keep this analysis defensible: 

• Feasibility and control: the action must be genuinely available to management, within its control, and consistent with the business model. IAS 12's framing - actions the entity 'would take' - is deliberate. Purely theoretical options do not qualify. 
• Modelling the tax effect properly: include only the incremental taxable profit the action creates, in the right period, with the right character (ordinary vs. capital). Factor in any transaction costs, governance approvals, or tax costs the action would trigger. 

2.4 When to recognise a DTA - summary table 

2.5  Examples

2.5.1 Unused tax losses with expiry

Note: IAS 12 requires reassessment at every reporting date. Recognise previously unrecognised DTAs when recovery becomes probable; derecognise if recovery is no longer probable 

2.5.2 Unused tax losses with annual utilisation caps  

Projections

Note: Even with an indefinite carryforward and a relatively generous 75% cap, $ 150 of losses remain unrecognised because forecast profits taper sharply in Years 3 and 4. A preparer who simply compared total losses ($ 1,200) to total forecast profit ($ 1,400) and concluded the full DTA of $ 108 was supportable would overstate the asset by $ 13.5. The year-by-year model is not optional - the cap and the profit profile interact, and the answer changes as the forecast is updated each period.

2.5.3 Tax planning opportunity supports additional DTA 

3. The initial recognition exception

3.1  The rule

IAS 12 prohibits recognising deferred tax on initial recognition of certain assets or liabilities. A deferred tax liability arising from the initial recognition of an asset or liability is not recognised when the transaction: (i) is not a business combination; (ii) at the time of the transaction, affects neither accounting profit nor taxable profit; and (iii) at the time of the transaction, does not give rise to equal taxable and deductible temporary differences. A parallel prohibition applies to DTAs arising from initial recognition in the same kind of transaction. 

The rationale in IAS 12 is transparency: if deferred tax were recognised, the entity would need to adjust the asset or liability's initial carrying amount by the same amount, which IAS 12 considers would make financial statements less transparent. The reason is straightforward - you would be marking down an asset on the day of purchase by an amount that has nothing to do with its value, condition, or the wisdom of buying it. A reader seeing a machine purchased for $ 1,000 immediately appearing on the balance sheet at $ 750 would reasonably ask what went wrong, when the answer is simply that a tax timing difference arose at the moment of purchase. The write-down signals a problem where none exists, and that is precisely what IAS 12 is trying to avoid. 

Once the exception applies, subsequent changes in the unrecognised deferred tax balance (for example, as the asset is depreciated) are also not recognised. 

3.2  What the 2021 amendment changed 

The May 2021 amendments to IAS 12 narrowed the exception, so it does not apply to transactions that, on initial recognition, give rise to equal taxable and deductible temporary differences. This is the structural feature of leases under IFRS 16 (a right-of-use asset and a lease liability recognised simultaneously) and of decommissioning obligations (a restoration asset and a decommissioning provision recognised together). 

The amendments are effective for annual reporting periods beginning on or after 1 January 2023, with earlier application permitted. 

3.3  Example

Note: A taxable temporary difference of $ 1,000 arises (carrying amount $ 1,000 vs. tax base nil). However, IAS 12 prohibits recognising the DTL because: (i) this is not a business combination; (ii) the transaction affected neither accounting profit nor taxable profit at the time (the company simply converted one asset (cash) into another (the license); and (iii) it does not give rise to equal taxable and deductible temporary differences.

4. Leases and decommissioning obligations

4.1  Why leases are different after the 2021 amendment 

At IFRS 16 lease commencement, a lessee recognises a right-of-use (ROU) asset and a lease liability simultaneously. Depending on tax law, this can create equal taxable and deductible temporary differences at day one - exactly the pattern that IAS 12 now carves out from the initial recognition exception (meaning that where this pattern arises, recognition of both the DTL and the DTA is required, not merely permitted). 

The deferred tax outcome for any specific lease depends on how the relevant tax law allocates deductions: to the asset side (treating the ROU asset as a depreciable asset), to the liability side (treating lease payments as deductible when paid), or some combination. IAS 12's illustrative example explicitly shows that where deductions follow the liability (i.e., deductions arise as lease payments are made), the tax base of the lease liability is nil and the tax base of the corresponding component of the ROU asset cost is also nil, creating equal and offsetting temporary differences.  

4.2  Example

Step 2 - Temporary differences at commencement:

Note: UAE corporate tax law generally follows IFRS accounting for depreciation and broadly aligns with IFRS 16 for leases, which means the book/tax differences on leases may be limited in the UAE compared to other GCC jurisdictions. However, preparers should confirm the specific UAE CT treatment for their lease type. In KSA, Qatar, Kuwait and Oman, where tax depreciation follows prescribed rates on a declining-balance or straight-line basis, ROU assets will likely create taxable temporary differences that do not perfectly mirror the lease liability's deductible temporary difference, requiring careful modelling of each component. 

4.3  Decommissioning obligations - same structural logic as leases 

Note: The initial recognition exception does not apply because the transaction gives rise to equal taxable and deductible temporary differences - the same structural reason as for leases. However, unlike leases where the asset and liability unwind on broadly similar schedules, the decommissioning asset depreciates steadily while the provision grows each year as the discount unwinds. The two temporary differences therefore diverge over time - the DTL shrinks while the DTA grows- and each must be tracked separately at every reporting date. They only both reach nil when the actual restoration costs are paid, at which point the tax deduction is finally received and the DTA is derecognised.

5. Business combinations and goodwill

5.1  The rule: deferred tax is part of acquisition accounting

In a business combination, the acquirer measures identifiable assets acquired and liabilities assumed at acquisition-date fair values under IFRS 3. IAS 12 requires deferred tax assets and liabilities arising from the combination - typically from differences between the fair value of identified assets/liabilities and their tax bases - to be recognised as part of acquisition accounting. Critically, these deferred tax balances affect the amount of goodwill (or bargain purchase gain) recognised. 

5.2  The goodwill exception 

IAS 12 prohibits recognising a DTL on the initial recognition of goodwill. The reason is structural: goodwill is a residual, so recognising a DTL would automatically increase the goodwill balance by the same amount, creating a larger temporary difference, a larger DTL, and so on - a circular loop with no end point. 

The prohibition is however narrow. It only blocks the DTL that exists on day one. Where tax law permits goodwill amortisation - as in KSA and Oman - the tax base equals the carrying amount at acquisition and no temporary difference exists initially. As tax amortisation reduces the tax base in subsequent years while the IFRS carrying amount stays flat, a taxable temporary difference emerges that was not there on day one. That subsequent difference falls outside the prohibition entirely and a DTL must be recognised and tracked as it grows. 

Where tax law does not permit goodwill amortisation  - as in Qatar and Kuwait - the tax base is nil from day one and the full carrying amount is a permanent difference. No DTL is recognised at any point. See Part I for GCC depreciation rates on goodwill. 

Note: Preparers working on GCC acquisitions should confirm whether the acquiree's jurisdiction recognises stepped-up tax bases on acquisition. In some jurisdictions, when a business is acquired, the tax authority resets the tax base of the acquired assets to their acquisition-date fair values - meaning the acquirer gets tax depreciation on what it actually paid. Most GCC jurisdictions do not do this: the tax base of the acquired assets remains at its pre-acquisition historical cost regardless of what the acquirer paid. The gap between the higher IFRS fair value and the lower historical tax base is therefore a taxable temporary difference that must be recognised as a DTL on acquisition day, increasing goodwill accordingly.

6. Outside-basis differences: subsidiaries, associates, and branches 

6.1  What an outside-basis difference is 

A temporary difference can arise when the carrying amount of an investment in a subsidiary, branch, associate, or joint arrangement differs from the tax base of that investment (often its original cost). Common causes in GCC group structures include: accumulated undistributed profits of subsidiaries; foreign currency translation effects in consolidated statements; and write-downs of investment carrying values. 

6.2  Recognising a DTL: the two conditions for exemption 

IAS 12's default is to recognise a DTL for all taxable temporary differences on such investments. The DTL is not recognised only if both conditions are satisfied: (a) the investor can control the timing of reversal; and (b) it is probable the temporary difference will not reverse in the foreseeable future. 

A parent generally controls its subsidiary's dividend policy and can therefore satisfy (a). If it also determines that accumulated profits will not be distributed in the foreseeable future, it does not recognise the DTL. For branches, the same considerations apply. For associates, the investor usually cannot control dividend policy - absent a specific agreement, the DTL is recognised. 

6.3  Recognising a DTA: the stricter test 

For deductible outside-basis temporary differences, IAS 12 applies a stricter test: a DTA is recognised only if it is probable that both (a) the temporary difference will reverse in the foreseeable future, and (b) taxable profit will be available to utilise it. 

6.4  Example: DTL on subsidiary profits - distribution expected 

Note: In UAE, participation exemptions can eliminate an outside-basis DTL entirely, but preparers must confirm eligibility for each specific investment. Where exemption status is uncertain, a DTL  should be provisionally recognised. The IAS 12 para 39 exception (no distribution expected) can also relieve the DTL where the parent can demonstrate control and a clear no-distribution policy - particularly common in GCC group structures where retained earnings are reinvested in regional expansion.

7. Presentation: profit or loss, OCI, or equity? 

The governing principle in IAS 12 is straightforward: the tax effect of a transaction follows the transaction itself. If the underlying item is in profit or loss, the deferred tax goes to profit or loss. If it is in OCI, the deferred tax goes to OCI. If it is directly in equity, so is the deferred tax. IAS 12 also acknowledges that in exceptional circumstances exact allocation may be impracticable, allowing a reasonable pro rata approach. 

8. Pillar Two and IAS 12 

8.1  The mandatory exception 

In May 2023, the IASB amended IAS 12 to address the OECD Pillar Two model rules. The amendment introduces a mandatory exception: entities neither recognise nor disclose deferred tax assets and liabilities related to Pillar Two income taxes. The IASB introduced the exception as a temporary response while continuing to monitor implementation issues and the longer-term accounting implications of Pillar Two taxes. 

8.2  What must be disclosed 

Despite the deferred tax exception, IAS 12 introduces targeted disclosure requirements: 

• A statement that the entity has applied the Pillar Two deferred tax exception. 
• Separate disclosure of current tax expense (or income) related to Pillar Two. 
• For periods when Pillar Two legislation is enacted or substantively enacted but not yet in effect: qualitative and quantitative information about the entity's exposure (or a statement that the information is not known or reasonably estimable, together with a description of the entity's progress in assessing its exposure). Quantitative information can be provided as an indicative range rather than a precise figure - IAS 12 does not require full modelling of all Pillar Two rules for this purpose. 

9. Conclusion 

Deferred tax accounting becomes most demanding not in the mechanics of identifying temporary differences - covered in Part I - but in the judgment calls around recognition, the application of carefully scoped exceptions, and the practical constraints that GCC tax law imposes on what a well-computed DTA is actually worth. 

Three habits tend to separate robust deferred tax work from work that attracts audit queries. First, build a year-by-year utilisation model rather than comparing gross balances to total forecast profit - annual caps in KSA and the UAE mean the shortcut overstates the recoverable DTA. Second, document the initial recognition exception analysis explicitly for every transaction involving an asset and a liability recognised simultaneously, confirming whether the 2021 amendment applies. Third, treat outside-basis differences as a live position to be reassessed each period, not a one-time conclusion - particularly in GCC groups where dividend policies, participation exemption eligibility, and cross-border tax rates change.
