26. The following are examples of deductible temporary differences which 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 enterprise or when retirement benefits are paid by the enterprise. 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 enterprise 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) the cost of a business combination is allocated by recognising the identifiable assets acquired and liabilities assumed 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.

Editorial note: Sub-paragraph (c) substituted by IFRS 3 with effect for business combinations for which the agreement date is on or after 31 March 2004, subject to further transitional provisions. Previously "(c) in a business combination that is an acquisition, the cost of the acquisition is allocated to the assets and liabilities recognised, by reference to their fair values at the date of the exchange transaction. When a liability is recognised on the acquisition 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 where 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"
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 enterprise only if it earns sufficient taxable profits against which the deductions can be offset. Therefore, an enterprise recognises deferred tax assets only when it is probable that taxable profits will be available against which the deductible temporary differences can be utilised.
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 enterprise 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 enterprise 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 enterprise that will create taxable profit in appropriate periods.
30. Tax planning opportunities are actions that the enterprise 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.

31. When an enterprise has a history of recent losses, the enterprise considers the guidance in paragraphs 35 and 36.

"Negative Goodwill

32 This Standard does not permit the recognition of a deferred tax asset arising from deductible temporary differences associated with negative goodwill which is treated as deferred income in accordance with IAS 22, Business Combinations, because negative goodwill is a residual and the recognition of the deferred tax asset would increase the carrying amount of negative goodwill. "
Initial Recognition of an Asset or Liability
33. One case when a deferred tax asset arises on initial recognition of an asset is when a non-taxable government grant related to an asset is deducted in arriving at the carrying amount of the asset but, for tax purposes, is not deducted from the asset's depreciable amount (in other words its tax base); the carrying amount of the asset is less than its tax base and this gives rise to a deductible temporary difference. Government grants may also be set up as deferred income in which case the difference between the deferred income and its tax base of nil is a deductible temporary difference. Whichever method of presentation an enterprise adopts, the enterprise does not recognise the resulting deferred tax asset, for the reason given in paragraph 22.

Unused Tax Losses and Unused Tax Credits
34. A deferred tax asset should be recognised for the carryforward of unused tax losses and unused tax credits to the extent that it is probable that future taxable profit will be available against which the unused tax losses and unused tax credits can be utilised.
35. The criteria for recognising deferred tax assets arising from the carryforward of unused tax losses and tax credits are the same as the criteria for recognising deferred tax assets arising from deductible temporary differences. However, the existence of unused tax losses is strong evidence that future taxable profit may not be available. Therefore, when an enterprise has a history of recent losses, the enterprise recognises a deferred tax asset arising from unused tax losses or tax credits only to the extent that the enterprise has sufficient taxable temporary differences or there is convincing other evidence that sufficient taxable profit will be available against which the unused tax losses or unused tax credits can be utilised by the enterprise. In such circumstances, paragraph 82 requires disclosure of the amount of the deferred tax asset and the nature of the evidence supporting its recognition.
36. An enterprise considers the following criteria in assessing the probability that taxable profit will be available against which the unused tax losses or unused tax credits can be utilised:
(a) whether the enterprise has sufficient taxable temporary differences relating to the same taxation authority and the same taxable entity, which will result in taxable amounts against which the unused tax losses or unused tax credits can be utilised before they expire;
(b) whether it is probable that the enterprise will have taxable profits before the unused tax losses or unused tax credits expire;
(c) whether the unused tax losses result from identifiable causes which are unlikely to recur; and
(d) whether tax planning opportunities (see paragraph 30) are available to the enterprise that will create taxable profit in the period in which the unused tax losses or unused tax credits can be utilised.
To the extent that it is not probable that taxable profit will be available against which the unused tax losses or unused tax credits can be utilised, the deferred tax asset is not recognised.

Re-assessment of Unrecognised Deferred Tax Assets
37. At each balance sheet date, an enterprise re-assesses unrecognised deferred tax assets. The enterprise recognises a previously unrecognised deferred tax asset to the extent that it has become probable that future taxable profit will allow the deferred tax asset to be recovered. For example, an improvement in trading conditions may make it more probable that the enterprise will be able to generate sufficient taxable profit in the future for the deferred tax asset to meet the recognition criteria set out in paragraphs 24 or 34. Another example is when an enterprise re-assesses deferred tax assets at the date of a business combination or subsequently (see paragraphs 67 and 68).
Investments in Subsidiaries, Branches and Associates and Interests in Joint Ventures

38. Temporary differences arise when the carrying amount of investments in subsidiaries, branches and associates or interests in joint ventures (namely the parent or investor's share of the net assets of the subsidiary, branch, associate or investee, including the carrying amount of goodwill) becomes different from the tax base (which is often cost) of the investment or interest. Such differences may arise in a number of different circumstances, for example:
(a) the existence of undistributed profits of subsidiaries, branches, associates and joint ventures;
(b) changes in foreign exchange rates when a parent and its subsidiary are based in different countries; and
(c) a reduction in the carrying amount of an investment in an associate to its recoverable amount.
In consolidated financial statements, the temporary difference may be different from the temporary difference associated with that investment in the parent's separate financial statements if the parent carries the investment in its separate financial statements at cost or revalued amount.
39. An enterprise should recognise a deferred tax liability for all taxable temporary differences associated with investments in subsidiaries, branches and associates, and interests in joint ventures, except to the extent that both of the following conditions are satisfied:
(a) the parent, investor or venturer is able to control the timing of the reversal of the temporary difference; and
(b) it is probable that the temporary difference will not reverse in the foreseeable future.

40. As a parent controls the dividend policy of its subsidiary, it is able to control the timing of the reversal of temporary differences associated with that investment (including the temporary differences arising not only from undistributed profits but also from any foreign exchange translation differences). Furthermore, it would often be impracticable to determine the amount of income taxes that would be payable when the temporary difference reverses. Therefore, when the parent has determined that those profits will not be distributed in the foreseeable future the parent does not recognise a deferred tax liability. The same considerations apply to investments in branches.
41. The non-monetary assets and liabilities of an entity are measured in its functional currency (see IAS 21 The Effects of Changes in Foreign Exchange Rates). If the entity's taxable profit or tax loss (and, hence, the tax base of its non-monetary assets and liabilities) is determined in a different currency, changes in the exchange rate give rise to temporary differences that result in a recognised deferred tax liability or (subject to paragraph 24) asset. The resulting deferred tax is charged or credited to profit or loss (see paragraph 58).
Editorial note: Substituted by improvements project standard IAS 21 with effect for annual periods beginning on or after 1 January 2005. If an entity applies this Standard for an earlier period, these amendments shall be applied for that earlier period. Previously "An enterprise accounts in its own currency for the non-monetary assets and liabilities of a foreign operation that is integral to the enterprise's operations (see IAS 21, The Effects of Changes in Foreign Exchange Rates). Where the foreign operation's taxable profit or tax loss (and, hence, the tax base of its non-monetary assets and liabilities) is determined in the foreign currency, changes in the exchange rate give rise to temporary differences. Because such temporary differences relate to the foreign operation's own assets and liabilities, rather than to the reporting enterprise's investment in that foreign operation, the reporting enterprise recognises the resulting deferred tax liability or (subject to paragraph 24) asset. The resulting deferred tax is charged or credited in the income statement (see paragraph 58)."

42. An investor in an associate does not control that enterprise and is usually not in a position to determine its dividend policy. Therefore, in the absence of an agreement requiring that the profits of the associate will not be distributed in the foreseeable future, an investor recognises a deferred tax liability arising from taxable temporary differences associated with its investment in the associate. In some cases, an investor may not be able to determine the amount of tax that would be payable if it recovers the cost of its investment in an associate, but can determine that it will equal or exceed a minimum amount. In such cases, the deferred tax liability is measured at this amount.
43. The arrangement between the parties to a joint venture usually deals with the sharing of the profits and identifies whether decisions on such matters require the consent of all the venturers or a specified majority of the venturers. When the venturer can control the sharing of profits and it is probable that the profits will not be distributed in the foreseeable future, a deferred tax liability is not recognised.

44. An enterprise should recognise a deferred tax asset for all deductible temporary differences arising from investments in subsidiaries, branches and associates, and interests in joint ventures, to the extent that, and only to the extent that, it is probable that:
(a) the temporary difference will reverse in the foreseeable future; and
(b) taxable profit will be available against which the temporary difference can be utilised.
45. In deciding whether a deferred tax asset is recognised for deductible temporary differences associated with its investments in subsidiaries, branches and associates, and its interests in joint ventures, an enterprise considers the guidance set out in paragraphs 28 to 31.
Measurement
46. Current tax liabilities (assets) for the current and prior periods should be measured at the amount expected to be paid to (recovered from) the taxation authorities, using the tax rates (and tax laws) that have been enacted or substantively enacted by the balance sheet date.
47. Deferred tax assets and liabilities should be measured at the tax rates that are expected to apply to the period when the asset is realised or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted by the balance sheet date.
48. Current and deferred tax assets and liabilities are usually measured using the tax rates (and tax laws) that have been enacted. However, in some jurisdictions, announcements of tax rates (and tax laws) by the government have the substantive effect of actual enactment, which may follow the announcement by a period of several months. In these circumstances, tax assets and liabilities are measured using the announced tax rate (and tax laws).
