87B. It would sometimes not be practicable to compute the total amount of the potential income tax consequences that would result from the payment of dividends to shareholders. This may be the case, for example, where an enterprise has a large number of foreign subsidiaries. However, even in such circumstances, some portions of the total amount may be easily determinable. For example, in a consolidated group, a parent and some of its subsidiaries may have paid income taxes at a higher rate on undistributed profits and be aware of the amount that would be refunded on the payment of future dividends to shareholders from consolidated retained earnings. In this case, that refundable amount is disclosed. If applicable, the enterprise also discloses that there are additional potential income tax consequences not practicably determinable. In the parent's separate financial statements, if any, the disclosure of the potential income tax consequences relates to the parent's retained earnings.

86. The average effective tax rate is the tax expense (income) divided by the accounting profit.
87. It would often be impracticable to compute the amount of unrecognised deferred tax liabilities arising from investments in subsidiaries, branches and associates and interests in joint ventures (see paragraph 39). Therefore, this Standard requires an enterprise to disclose the aggregate amount of the underlying temporary differences but does not require disclosure of the deferred tax liabilities. Nevertheless, where practicable, enterprises are encouraged to disclose the amounts of the unrecognised deferred tax liabilities because financial statement users may find such information useful.
87A. Paragraph 82A requires an enterprise to disclose the nature of the potential income tax consequences that would result from the payment of dividends to its shareholders. An enterprise discloses the important features of the income tax systems and the factors that will affect the amount of the potential income tax consequences of dividends.

84. The disclosures required by paragraph 81(c) enable users of financial statements to understand whether the relationship between tax expense (income) and accounting profit is unusual and to understand the significant factors that could affect that relationship in the future. The relationship between tax expense (income) and accounting profit may be affected by such factors as revenue that is exempt from taxation, expenses that are not deductible in determining taxable profit (tax loss), the effect of tax losses and the effect of foreign tax rates.
85. In explaining the relationship between tax expense (income) and accounting profit, an enterprise uses an applicable tax rate that provides the most meaningful information to the users of its financial statements. Often, the most meaningful rate is the domestic rate of tax in the country in which the enterprise is domiciled, aggregating the tax rate applied for national taxes with the rates applied for any local taxes which are computed on a substantially similar level of taxable profit (tax loss). However, for an enterprise operating in several jurisdictions, it may be more meaningful to aggregate separate reconciliations prepared using the domestic rate in each individual jurisdiction. The following example illustrates how the selection of the applicable tax rate affects the presentation of the numerical reconciliation.

82. An enterprise should disclose the amount of a deferred tax asset and the nature of the evidence supporting its recognition, when:
(a) the utilisation of the deferred tax asset is dependent on future taxable profits in excess of the profits arising from the reversal of existing taxable temporary differences; and
(b) the enterprise has suffered a loss in either the current or preceding period in the tax jurisdiction to which the deferred tax asset relates.
82A. In the circumstances described in paragraph 52A, an enterprise should disclose the nature of the potential income tax consequences that would result from the payment of dividends to its shareholders. In addition, the enterprise should disclose the amounts of the potential income tax consequences practicably determinable and whether there are any potential income tax consequences not practicably determinable.

Editorial note: Deleted by improvements project standard IAS 8 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 discloses the nature and amount of each extraordinary item either on the face of the income statement or in the notes to the financial statements. When this disclosure is made in the notes to the financial statements, the total amount of all extraordinary items is disclosed on the face of the income statement, net of the aggregate related tax expense (income). Although financial statement users may find the disclosure of the tax expense (income) related to each extraordinary item useful, it is sometimes difficult to allocate tax expense (income) between such items. Under these circumstances tax expense (income) relating to extraordinary items may be disclosed in the aggregate."

81. The following should also be disclosed separately:
(a) the aggregate current and deferred tax relating to items that are charged or credited to equity;
(b) […]
(c) an explanation of the relationship between tax expense (income) and accounting profit in either or both of the following forms:
(i) a numerical reconciliation between tax expense (income) and the product of accounting profit multiplied by the applicable tax rate(s), disclosing also the basis on which the applicable tax rate(s) is (are) computed; or
(ii) a numerical reconciliation between the average effective tax rate and the applicable tax rate, disclosing also the basis on which the applicable tax rate is computed;
(d) an explanation of changes in the applicable tax rate(s) compared to the previous accounting period;
(e) the amount (and expiry date, if any) of deductible temporary differences, unused tax losses, and unused tax credits for which no deferred tax asset is recognised in the balance sheet;
(f) the aggregate amount of temporary differences associated with investments in subsidiaries, branches and associates and interests in joint ventures, for which deferred tax liabilities have not been recognised (see paragraph 39);
(g) in respect of each type of temporary difference, and in respect of each type of unused tax losses and unused tax credits:
(i) the amount of the deferred tax assets and liabilities recognised in the balance sheet for each period presented;
(ii) the amount of the deferred tax income or expense recognised in the income statement, if this is not apparent from the changes in the amounts recognised in the balance sheet;
(h) in respect of discontinued operations, the tax expense relating to:
(i) the gain or loss on discontinuance; and
(ii) the profit or loss from the ordinary activities of the discontinued operation for the period, together with the corresponding amounts for each prior period presented; and
(i) the amount of income tax consequences of dividends to shareholders of the enterprise that were proposed or declared before the financial statements were authorised for issue, but are not recognised as a liability in the financial statements.

76. In rare circumstances, an enterprise may have a legally enforceable right of set-off, and an intention to settle net, for some periods but not for others. In such rare circumstances, detailed scheduling may be required to establish reliably whether the deferred tax liability of one taxable entity will result in increased tax payments in the same period in which a deferred tax asset of another taxable entity will result in decreased payments by that second taxable entity.

Tax Expense
Tax Expense (Income) related to Profit or Loss from Ordinary Activities
77. The tax expense (income) related to profit or loss from ordinary activities should be presented on the face of the income statement.
Exchange Differences on Deferred Foreign Tax Liabilities or Assets
78. IAS 21, The Effects of Changes in Foreign Exchange Rates, requires certain exchange differences to be recognised as income or expense but does not specify where such differences should be presented in the income statement. Accordingly, where exchange differences on deferred foreign tax liabilities or assets are recognised in the income statement, such differences may be classified as deferred tax expense (income) if that presentation is considered to be the most useful to financial statement users.
Disclosure
79. The major components of tax expense (income) should be disclosed separately.
80. Components of tax expense (income) may include:
(a) current tax expense (income);
(b) any adjustments recognised in the period for current tax of prior periods;
(c) the amount of deferred tax expense (income) relating to the origination and reversal of temporary differences;
(d) the amount of deferred tax expense (income) relating to changes in tax rates or the imposition of new taxes;
(e) the amount of the benefit arising from a previously unrecognised tax loss, tax credit or temporary difference of a prior period that is used to reduce current tax expense;
(f) the amount of the benefit from a previously unrecognised tax loss, tax credit or temporary difference of a prior period that is used to reduce deferred tax expense;
(g) deferred tax expense arising from the write-down, or reversal of a previous write-down, of a deferred tax asset in accordance with paragraph 56; and
(h) the amount of tax expense (income) relating to those changes in accounting policies and errors that are included in profit or loss in accordance with IAS 8, because they cannot be accounted for retrospectively.
Editorial note: Sub-paragraph (b) substituted by improvements project standard IAS 8 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 "(h) the amount of tax expense (income) relating to those changes in accounting policies and fundamental errors which are included in the determination of net profit or loss for the period in accordance with the allowed alternative treatment in IAS 8, Net Profit or Loss for the Period, Fundamental Errors and Changes in Accounting Policies."

73. In consolidated financial statements, a current tax asset of one enterprise in a group is offset against a current tax liability of another enterprise in the group if, and only if, the enterprises concerned have a legally enforceable right to make or receive a single net payment and the enterprises intend to make or receive such a net payment or to recover the asset and settle the liability simultaneously.
74. An enterprise should offset deferred tax assets and deferred tax liabilities if, and only if:
(a) the enterprise has a legally enforceable right to set off current tax assets against current tax liabilities; and
(b) the deferred tax assets and the deferred tax liabilities relate to income taxes levied by the same taxation authority on either:
(i) the same taxable entity; or
(ii) different taxable entities which intend either to settle current tax liabilities and assets on a net basis, or to realise the assets and settle the liabilities simultaneously, in each future period in which significant amounts of deferred tax liabilities or assets are expected to be settled or recovered.
75. To avoid the need for detailed scheduling of the timing of the reversal of each temporary difference, this Standard requires an enterprise to set off a deferred tax asset against a deferred tax liability of the same taxable entity if, and only if, they relate to income taxes levied by the same taxation authority and the enterprise has a legally enforceable right to set off current tax assets against current tax liabilities.

Editorial note : Deleted by improvements project standard IAS 1 with effect for annual periods beginning on or after 1 January 2005. If an entity applies IAS 1 for an earlier period, these amendments shall be applied for that earlier period. Previously "When an enterprise makes a distinction between current and non-current assets and liabilities in its financial statements, it should not classify deferred tax assets (liabilities) as current assets (liabilities)."
Offset
71. An enterprise should offset current tax assets and current tax liabilities if, and only if, the enterprise:
(a) has a legally enforceable right to set off the recognised amounts; and
(b) intends either to settle on a net basis, or to realise the asset and settle the liability simultaneously.
72. Although current tax assets and liabilities are separately recognised and measured they are offset in the balance sheet subject to criteria similar to those established for financial instruments in IAS 32, Financial Instruments: Disclosure and Presentation. An enterprise will normally have a legally enforceable right to set off a current tax asset against a current tax liability when they relate to income taxes levied by the same taxation authority and the taxation authority permits the enterprise to make or receive a single net payment.

68C. As noted in paragraph 68A, the amount of the tax deduction (or estimated future tax deduction, measured in accordance with paragraph 68B) may differ from the related cumulative remuneration expense. Paragraph 58 of the Standard requires that current and deferred tax should be recognised as income or an expense and included in profit or loss for the period, except to the extent that the tax arises from (a) a transaction or event which is recognised, in the same or a different period, directly in equity, or (b) a business combination that is an acquisition. If the amount of the tax deduction (or estimated future tax deduction) exceeds the amount of the related cumulative remuneration expense, this indicates that the tax deduction relates not only to remuneration expense but also to an equity item. In this situation, the excess of the associated current or deferred tax should be recognised directly in equity.
Editorial note: Paragraph 68C inserted by IFRS 2 with effect for accounting periods beginning on or after 1 January 2005. If an entity applies IFRS 2 for an earlier period, these amendments shall be applied for that earlier period.

IAS Correction List 9, May 2004 also inserts paragraph 68C at this place, without reference to the insertion of 68C by IFRS 2. The May 2004 wording of the paragraph is "68C. As noted in paragraph 68A, the amount of the tax deduction (or estimated future tax deduction, measured in accordance with paragraph 68B) may differ from the related cumulative remuneration expense. Paragraph 58 of the Standard requires that current and deferred tax should be recognised as income or an expense and included in profit or loss for the period, except to the extent that the tax arises from (a) a transaction or event which is recognised, in the same or a different period, directly in equity, or (b) a business combination. If the amount of the tax deduction (or estimated future tax deduction) exceeds the amount of the related cumulative remuneration expense, this indicates that the tax deduction relates not only to remuneration expense but also to an equity item. In this situation, the excess of the associated current or deferred tax should be recognised directly in equity." It is likely that another correction will be forthcoming.

68A. In some tax jurisdictions, an entity receives a tax deduction (ie an amount that is deductible in determining taxable profit) that relates to remuneration paid in shares, share options or other equity instruments of the entity. The amount of that tax deduction may differ from the related cumulative remuneration expense, and may arise in a later accounting period. For example, in some jurisdictions, an entity may recognise an expense for the consumption of employee services received as consideration for share options granted, in accordance with IFRS 2 Share-based Payment, and not receive a tax deduction until the share options are exercised, with the measurement of the tax deduction based on the entity's share price at the date of exercise.
Editorial note: Paragraph 68A and heading preceding inserted by IFRS 2 with effect for accounting periods beginning on or after 1 January 2005. If an entity applies IFRS 2 for an earlier period, these amendments shall be applied for that earlier period.
68B. As with the research costs discussed in paragraphs 9 and 26(b) of this Standard, the difference between the tax base of the employee services received to date (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. If the amount the taxation authorities will permit as a deduction in future periods is not known at the end of the period, it should be estimated, based on information available at the end of the period. For example, if the amount that the taxation authorities will permit as a deduction in future periods is dependent upon the entity's share price at a future date, the measurement of the deductible temporary difference should be based on the entity's share price at the end of the period.
Editorial note: Paragraph 68B inserted by IFRS 2 with effect for accounting periods beginning on or after 1 January 2005. If an entity applies IFRS 2 for an earlier period, these amendments shall be applied for that earlier period.
