26 The following are examples of deductible temporary differences that result in deferred tax assets: (a) retirement benefit costs may be deducted in determining accounting profit as service is provided by the employee, but deducted in determining taxable profit either when contributions are paid to a fund by the entity or when retirement benefits are paid by the entity. A temporary difference exists between the carrying amount of the liability and its tax base; the tax base of the liability is usually nil. Such a deductible temporary difference results in a deferred tax asset as economic benefits will flow to the entity in the form of a deduction from taxable profits when contributions or retirement benefits are paid; (b) research costs are recognised as an expense in determining accounting profit in the period in which they are incurred but may not be permitted as a deduction in determining taxable profit (tax loss) until a later period. The difference between the tax base of the research costs, being the amount the taxation authorities will permit as a deduction in future periods, and the carrying amount of nil is a deductible temporary difference that results in a deferred tax asset; (c) with limited exceptions, an entity recognises the identifiable assets acquired and liabilities assumed in a business combination at their fair values at the acquisition date. When a liability assumed is recognised at the acquisition date but the related costs are not deducted in determining taxable profits until a later period, a deductible temporary difference arises which results in a deferred tax asset. A deferred tax asset also arises when the fair value of an identifiable asset acquired is less than its tax base. In both cases, the resulting deferred tax asset affects goodwill (see paragraph 66); and (d) certain assets may be carried at fair value, or may be revalued, without an equivalent adjustment being made for tax purposes (see paragraph 20). A deductible temporary difference arises if the tax base of the asset exceeds its carrying amount.   | Example illustrating paragraph 26(d) | | Identification of a deductible temporary difference at the end of Year 2:<br>Entity A purchases for CU1,000, at the beginning of Year 1, a debt instrument with a nominal value of CU1,000 payable on maturity in 5 years with an interest rate of 2% payable at the end of each year. The effective interest rate is 2%. The debt instrument is measured at fair value. | | At the end of Year 2, the fair value of the debt instrument has decreased to CU918 as a result of an increase in market interest rates to 5%. It is probable that Entity A will collect all the contractual cash flows if it continues to hold the debt instrument. | | Any gains (losses) on the debt instrument are taxable (deductible) only when realised. The gains (losses) arising on the sale or maturity of the debt 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.<br>The difference between the carrying amount of the debt instrument in Entity A’s statement of financial position of CU918 and its tax base of CU1,000 gives rise to a deductible temporary difference of CU82 at the end of Year 2 (see paragraphs 20 and 26(d)), irrespective of whether Entity A expects to recover the carrying amount of the debt instrument by sale or by use, ie by holding it and collecting contractual cash flows, or a combination of both. | | This is because deductible temporary differences are differences between the carrying amount of an asset or liability in the statement of financial position and its tax base that will result in amounts that are deductible in determining taxable profit (tax loss) of future periods, when the carrying amount of the asset or liability is recovered or settled (see paragraph 5). Entity A obtains a deduction equivalent to the tax base of the asset of CU1,000 in determining taxable profit (tax loss) either on sale or on maturity. |   27 The reversal of deductible temporary differences results in deductions in determining taxable profits of future periods. However, economic benefits in the form of reductions in tax payments will flow to the entity only if it earns sufficient taxable profits against which the deductions can be offset. Therefore, an entity recognises deferred tax assets only when it is probable that taxable profits will be available against which the deductible temporary differences can be utilised. 27A When an entity assesses whether taxable profits will be available against which it can utilise a deductible temporary difference, it considers whether tax law restricts the sources of taxable profits against which it may make deductions on the reversal of that deductible temporary difference. If tax law imposes no such restrictions, an entity assesses a deductible temporary difference in combination with all of its other deductible temporary differences. However, if tax law restricts the utilisation of losses to deduction against income of a specific type, a deductible temporary difference is assessed in combination only with other deductible temporary differences of the appropriate type. 28 It is probable that taxable profit will be available against which a deductible temporary difference can be utilised when there are sufficient taxable temporary differences relating to the same taxation authority and the same taxable entity which are expected to reverse: (a) in the same period as the expected reversal of the deductible temporary difference; or (b) in periods into which a tax loss arising from the deferred tax asset can be carried back or forward. In such circumstances, the deferred tax asset is recognised in the period in which the deductible temporary differences arise. 29 When there are insufficient taxable temporary differences relating to the same taxation authority and the same taxable entity, the deferred tax asset is recognised to the extent that: (a) it is probable that the entity will have sufficient taxable profit relating to the same taxation authority and the same taxable entity in the same period as the reversal of the deductible temporary difference (or in the periods into which a tax loss arising from the deferred tax asset can be carried back or forward). In evaluating whether it will have sufficient taxable profit in future periods, an entity: (i)                     compares the deductible temporary differences with future taxable profit that excludes tax deductions resulting from the reversal of those deductible temporary differences. This comparison shows the extent to which the future taxable profit is sufficient for the entity to deduct the amounts resulting from the reversal of those deductible temporary differences; and (ii)                   ignores taxable amounts arising from deductible temporary differences that are expected to originate in future periods, because the deferred tax asset arising from these deductible temporary differences will itself require future taxable profit in order to be utilised; or (b) tax planning opportunities are available to the entity that will create taxable profit in appropriate periods. 29A The estimate of probable future taxable profit may include the recovery of some of an entity’s assets for more than their carrying amount if there is sufficient evidence that it is probable that the entity will achieve this. For example, when an asset is measured at fair value, the entity shall consider whether there is sufficient evidence to conclude that it is probable that the entity will recover the asset for more than its carrying amount. This may be the case, for example, when an entity expects to hold a fixed-rate debt instrument and collect the contractual cash flows. 30 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 credit carryforward. For example, in some jurisdictions, taxable profit may be created or increased by: (a) electing to have interest income taxed on either a received or receivable basis; (b) deferring the claim for certain deductions from taxable profit; (c) selling, and perhaps leasing back, assets that have appreciated but for which the tax base has not been adjusted to reflect such appreciation; and (d) 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.
