CSL 2025 Annual Report

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 and carried forward unused tax losses, only if it is probable that taxable profit will be available to utilise them. The carrying amount of deferred 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. As at 30 June 2025, $84m (2024: $278m) in deferred tax assets have not been recognised with respect to tax losses with expiry dates not yet lapsed. 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 tax asset is realised or when the deferred tax liability is settled. The Group continues to apply the mandatory temporary exemption regarding the recognition of deferred tax assets and liabilities related to Pillar Two and Domestic Minimum Tax incomes taxes in accordance with AASB 2023-2 Amendments to Australian Accounting Standards International Tax Reform – Pillar Two Model Rules. 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 OCI or directly in equity are also recognised in OCI or in equity, and not in the consolidated income statement. CSL Limited and its 100% owned Australian subsidiaries have formed a tax consolidated group effective from 1 July 2003. International Tax Reform – Pillar Two Model Rules The Organisation for Economic Co-Operation and Development (OECD) Pillar Two Model Rules apply to the Group from 1 July 2024. As such, the financial statements have been prepared with consideration of the Pillar Two legislation. Based on the analysis performed as at 30 June 2025, Pillar Two has not had a material impact on the current tax expense of the Group for the year ended 30 June 2025. 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. This includes matters such as the availability and timing of tax deductions and the application of the arm’s length principle to related party transactions, that 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 deferred taxes will be recorded as a credit or charge to the statement of comprehensive income. 102 Notes to the Financial Statements 102 Financial Report
