7.4
   Restrictions on recognition of deferred tax assets
   There is an essential difference between deferred tax liabilities and deferred tax assets.
   An entity’s deferred tax liabilities will crystallise if the entity recovers its existing net
   assets at their carrying amount. However, in order to realise its net deferred tax assets
   in full, an entity must earn profits in excess of those represented by the carrying amount
   of its net assets in order to generate sufficient taxable profits against which the
   deductions represented by deferred tax assets can be offset. Accordingly IAS 12 restricts
   the recognition of deferred tax assets to the extent that it is probable that taxable profit
   will be available against which the underlying deductible temporary differences can be
   utilised. [IAS 12.27].
   7.4.1
   Restrictions imposed by relevant tax laws
   When an entity assesses whether a deductible temporary difference is capable of being
   utilised, it must consider whether tax law restricts the sources of taxable profits against
   which deductions for this type of temporary difference are permitted. If tax law imposes
   no such restrictions, an entity can assess a deductible temporary difference in
   combination with all its other deductible temporary differences. However, if tax law
   restricts the utilisation of losses to deduction against a specific type of income, the
   recovery of a deductible temporary difference is assessed in combination only with
   other deductible temporary differences of the appropriate type. [IAS 12.27A].
   7.4.2
   Sources of ‘probable’ taxable profit – taxable temporary differences
   Before considering forecasts of future taxable profits, an entity should look to the
   deferred tax liabilities it has already recognised at the reporting date as a source of
   probable taxable profits that would allow any deductible temporary differences to be
   utilised. IAS 12 states that it is ‘probable’ that there will be sufficient taxable profit if a
   deductible temporary difference can be offset against a taxable temporary difference
   (deferred tax liability) relating to the same tax authority and the same taxable entity
   which will reverse in the same period as the asset, or in a period into which a loss arising
   from the asset may be carried back or forward. In such circumstances, a deferred tax
   asset is recognised. [IAS 12.28].
   There is no need at this stage to estimate the future taxable profits of the entity. If there
   are sufficient taxable temporary differences to justify the recognition of a deferred tax
   asset for deductible temporary differences, then the asset is recognised. The only
   condition to apply, as noted at 7.4.1 above, is that any deferred tax liability used as the
   basis for recognising a deferred tax asset represents a future tax liability against which
   the deductible temporary difference can actually be offset under the relevant tax law.
   [IAS 12.27A]. For example, in a tax jurisdiction where revenue and capital items are
   treated separately for tax purposes, a deferred tax asset representing a capital loss
   cannot be recognised by reference to a deferred tax liability relating to tax allowances
   received on PP&E in advance of the related depreciation expense.

   7.4.3
   Sources of ‘probable’ taxable profit – estimates of future taxable profits
   Estimates of future taxable profits are only required to justify the recoverability of those
   deductible temporary differences in excess of the amounts already ‘matched’ against
   deferred tax liabilities recognised at the reporting date in the manner described at 7.4.2
   above. Where there are insufficient taxable temporary differences relating to the same
   tax authority to offset deductible temporary differences, a deferred tax asset should be
   recognised to the extent that:
   • it is probable that in future periods there will be sufficient taxable profits:
   • relating to the same tax authority;
   • relating to the same taxable entity; and
   • arising in the same period as the reversal of the deductible temporary
   difference or in a period into which a loss arising from the deferred tax asset
   may be carried back or forward; or
   • tax planning opportunities are available that will create taxable profit in
   appropriate periods – see 7.4.4 below. [IAS 12.29].
   Where an entity has a history of recent losses it should also consider the guidance in
   IAS 12 for recognition of such losses (see 7.4.6 below). [IAS 12.31].
   7.4.3.A
   Ignore the origination of new future deductible temporary differences
   In assessing the availability of future taxable profits, an entity must ignore taxable
   amounts arising from deductible temporary differences expected to originate in future
   periods. This is because those new deductible differences will themselves require
   future taxable profit in order to be utilised. [IAS 12.29(a)(ii)].
   For example, suppose that in 2019 an entity charges £100 to profit or loss for which a tax
   deduction is not available until 2020, when the amount is settled. However, in 2020 a
   further £100 is expected to be charged to profit or loss, for which a deduction will be
   available in 2021, and so on for the foreseeable future. This will have the effect that,
   in 2019, the entity will pay tax on the £100 for which no deduction is made on the 2019
   tax return. In the tax return for 2020, there will be a deduction for that £100, but this will
   be offset by the add-back in the same tax return for the equivalent £100 charged for
   accounting purposes in 2020. If this cycle of ‘£100 deduction less £100 add-back’ is
   expected to be perpetuated in each tax return for the foreseeable future, there is never
   any real recovery of the tax paid on the £100 in 2019 and, in the absence of any other
   taxable profits, no deferred tax asset would be recognised.
   7.4.3.B
   Ignore the reversal of existing deductible temporary differences
   In 2016, the IASB added text to the standard to clarify that the estimate of probable
   future taxable profit should exclude the tax deductions resulting from the reversal of
   the deductible temporary differences that are themselves being assessed for recognition
   as an asset. [IAS 12.29(a)(i)]. This amendment was made following the IASB’s deliberations
   on the recognition of deferred tax assets for unrealised losses, as discussed at 7.4.5
   below. The effect of the amendment is to clarify that the measure of taxable profit used
   for assessing the utilisation of deductible temporary differences is different from the
   taxable profit on which income taxes are payable. [IAS 12.BC56].
   2404 Chapter 29
   The former is calculated before any allowances or deductions arising from the reversal of
   deductible temporary differences. The latter is the amount determined after the application
   of all applicable tax laws that gives rise to an entity’s liability to pay income tax. [IAS 12.5].
   7.4.4
   Tax planning opportunities and the recognition of deferred tax assets
   ‘Tax planning opportunities’ are actions that the entity would take in order to create or
   increase taxable income in a particular period before the expiry of a tax loss or tax
   cre
dit carryforward. IAS 12 notes that, in some jurisdictions, taxable profit may be
   created or increased by:
   • electing to have interest income taxed on either a received or receivable basis;
   • deferring the claim for certain deductions from taxable profit;
   • selling, and perhaps leasing back, assets that have appreciated but for which the
   tax base has not been adjusted to reflect such appreciation; and
   • selling an asset that generates non-taxable income (such as, in some jurisdictions,
   a government bond) in order to purchase another investment that generates
   taxable income.
   Where tax planning opportunities advance taxable profit from a later period to an
   earlier period, the utilisation of a tax loss or tax credit carryforward still depends on the
   existence of future taxable profit from sources other than future originating temporary
   differences. [IAS 12.30].
   The requirement to have regard to future tax planning opportunities applies only to the
   measurement of deferred tax assets. It does not apply to the measurement of deferred
   tax liabilities. Thus, for example, it would not be open to an entity subject to tax at 30%
   to argue that it should provide for deferred tax liabilities at some lower rate on the
   grounds that it intends to invest in assets attracting investment tax credits that will allow
   it to pay tax at that lower rate (see 8.4.1 below).
   IAS 12 describes tax planning opportunities as actions that the entity ‘would’ take – not
   those it ‘could’ take. In other words, they are restricted to future courses of action that
   the entity would actually undertake to realise such a deferred tax asset, and do not
   include actions that are theoretically possible but practically implausible, such as the
   sale of an asset essential to the ongoing operations of the entity. Only if such actions are
   both capable of being taken and are intended to be taken by the entity can it be said
   that the resulting tax planning would give rise to a ‘probable’ future taxable profit.
   Implementation of a tax planning opportunity may well entail significant direct costs or
   the loss of other tax benefits or both. Accordingly, any deferred tax asset recognised on
   the basis of a tax planning opportunity must be reduced by any cost of implementing
   that opportunity (measured, where applicable, on an after-tax basis).
   Moreover, IAS 12 regards tax planning opportunities as a component of future net
   taxable profits. Thus, where a tax planning opportunity exists, but the entity is expected
   to remain loss-making (such that the opportunity effectively will simply reduce future
   tax losses), we believe that such an opportunity does not generally form the basis for
   recognising a deferred tax asset, except to the extent that it will create net future taxable
   profits (see also 7.4.6 below).

   Unrealised losses on debt securities measured at fair value
   In January 2016, the IASB issued Recognition of Deferred Tax Assets for Unrealised
   Losses (Amendments to IAS 12). These amendments concluded deliberations started by
   the Interpretations Committee in May 2010 on the recognition of deferred tax assets for
   unrealised losses, for example on debt instruments measured at fair value. [IAS 12.BC1A].
   The Committee had been asked to provide guidance on how an entity determines whether
   to recognise a deferred tax asset under IAS 12 in the following circumstances: [IAS 12.BC37]
   (a) the entity has a debt instrument measured at fair value under IAS 39 and changes
   in market interest rates result in a decrease in the fair value of the debt instrument
   below its cost;
   (b) it is probable that the issuer of the debt instrument will make all the contractual
   payments;
   (c) the tax base of the debt instrument is its cost;
   (d) tax law does not allow a loss to be deducted on a debt instrument until the loss is
   realised for tax purposes;
   (e) the entity has the ability and intention to hold the debt instrument until the
   unrealised loss reverses (which may be at its maturity);
   (f) tax law distinguishes between capital gains and losses and ordinary income tax
   losses. While capital losses can only be offset against capital gains, ordinary losses
   can be offset against both capital gains and ordinary income; and
   (g) the entity has insufficient taxable temporary differences and no other probable taxable
   profits against which the entity can utilise those deductible temporary differences.
   The Interpretations Committee had identified diversity in practice because of
   uncertainty about the application of some of the principles in IAS 12, in particular in
   relation to the following:
   (a) The existence of a deductible temporary difference, when there are no tax
   consequences to the recovery of the principal on maturity; the holder of the debt
   instrument expects to hold it to maturity; and it is probable that the issuer will pay
   all the contractual cash flows. [IAS 12.BC38, BC39].
   (b) Whether it is appropriate for an entity to determine deductible temporary
   differences and taxable temporary differences on the basis of the asset’s carrying
   amount when at the same time it assumes that the asset is recovered for more than
   its carrying amount for the purposes of estimating probable future taxable profit
   against which deductible temporary differences are assessed for utilisation. This
   question is relevant when taxable profit from other sources is insufficient for the
   utilisation of the deductible temporary differences arising when the asset is
   measured at fair value. [IAS 12.BC38, BC47].
   (c) Whether the estimate of probable future taxable profit should include or exclude
   the effects of reversing the deductible temporary differences that are being
   assessed for recognition as an asset. [IAS 12.BC38, BC55].
   (d) The basis for assessing the recoverability of deductible temporary differences, i.e.
   for each deductible temporary difference separately, or in combination with other
   deductible temporary differences. This question is relevant, for example, when tax
   2406 Chapter 29
   law distinguishes capital gains and losses from other taxable gains and losses and
   capital losses can only be offset against capital gains. [IAS 12.BC38, BC57].
   Whilst the amendments to IAS 12 were framed around the above example of a fixed-rate
   debt instrument measured at fair value, the Board noted that the principle on which the
   amendments are based is not limited to any specific type or class of assets. [IAS 12.BC52].
   However, as noted at 7.4.5.B below, the IASB acknowledged the concerns raised by
   respondents that the amendments could be applied too broadly and highlighted the need
   for particular caution where assets are measured at fair value. In response to that concern,
   the Board noted that entities will need to have sufficient evidence on which to base their
   estimate of probable future taxable profit, including when that estimate involves the
   recovery of an asset for more than its carrying amount. [IAS 12.BC53].
   7.4.5.A
   The existence of a deductible temporary difference
   Because, in the case of many debt instruments, the collection of the principal on
   maturity does not give rise to a
ny liability for tax, some believed that the collection of
   the principal is a non-taxable event. Consequently, proponents of this view argued that
   a deductible temporary difference cannot exist when an entity asserts that the
   contractual payments will be received, because any difference between the debt
   instrument’s carrying amount and its higher tax base results from a loss that the entity
   expects never to realise for tax purposes. [IAS 12.BC40].
   The IASB rejected this argument. IAS 12 already states that a deductible temporary
   difference arises if the tax base of an asset exceeds its carrying amount. [IAS 12.20, 26(d)].
   The calculation of a temporary difference is based on the premise that the carrying
   amount of the asset will be recovered. [IAS 12.5]. The calculation of the temporary
   difference is not affected by possible future changes in the carrying amount of the asset.
   The Board considered that the economic benefit embodied in the related deferred tax
   asset results from the ability of the holder of the debt instrument to achieve future
   taxable gains in the amount of the deductible temporary difference without paying tax
   on those gains. This is the case where a previous impairment reverses, such that the
   entity recovers the original principal on the debt instrument. [IAS 12.BC42-44].
   Accordingly, the amendments add an example after paragraph 26 of IAS 12 to illustrate
   how a deductible temporary difference exists under paragraph 26(d).
   Example 29.21: Deductible temporary difference when the asset is valued below cost
   At the beginning of Year 1, Entity A purchases for $1,000 a debt instrument with a nominal value of $1,000
   payable at the end of Year 5 and with an interest rate of 2% payable at the end of each year. The effective
   interest rate is determined to be 2% and the debt instrument is measured at fair value.
   At the end of year 2, market interest rates have increased to 5%, causing the fair value of the debt instrument
   to decrease to $918. It is probable that Entity A will collect all the contractual cash flows if it continues to
   hold the debt instrument.
   Any gains or losses on the debt instrument are taxable or deductible only when realised. Gains or losses arising on
   the sale or maturity of the instrument are calculated for tax purposes as the difference between the amount collected
   and the original cost of the debt instrument. Accordingly, the tax base of the debt instrument is its original cost.
