Current taxes Current tax assets and liabilities are the amounts expected to be recovered from (or paid to) tax authorities, under the tax rates and laws in each jurisdiction. These include any rates or laws that are enacted or substantively enacted as at the balance sheet date. Deferred taxes Deferred tax liabilities are recognised for taxable temporary differences. Deferred tax assets are recognised for deductible temporary differences, carried forward unused tax assets and unused tax losses, only if it is probable that taxable profit will be available to utilise them. The carrying amount of deferred income tax assets is reviewed at the reporting date. If it is no longer probable that taxable profit will be available to utilise them, they are reduced accordingly. Deferred tax is measured using tax rates and laws that are enacted at the reporting date and are expected to apply when the related deferred income tax asset is realised or when the deferred income tax liability is settled. Deferred tax assets and liabilities are offset only if a legally enforceable right exists to set-off current tax assets against current tax liabilities and if they relate to the same taxable entity or group and the same taxation authority. Income taxes attributable to amounts recognised in other comprehensive income or directly in equity are also recognised in other comprehensive income or in equity, and not in the income statement. CSL Limited and its 100% owned Australian subsidiaries have formed a tax consolidated group effective from 1 July 2003. Key Judgements and Estimates The risk of uncertain tax positions, and recognition and recoverability of deferred tax assets, are regularly assessed. To do this requires judgements about the application of income tax legislation in jurisdictions in which the Group operates and the future operating performance of entities with carry forward losses. These judgements and assumptions, which include matters such as the availability and timing of tax deductions and the application of the arm’s length principle to related party transactions, are subject to risk and uncertainty. Changes in circumstances may alter expectations and affect the carrying amount of deferred tax assets and liabilities. Any resulting adjustment to the carrying value of a deferred tax itemwill be recorded as a credit or charge to the statement of comprehensive income. CSL Limited Annual Report 2021/22 108
