ÇELEBİ HAVA SERVİSİ ANONİM ŞİRKETİ VE BAĞLI ORTAKLIKLARI 100 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS FOR THE PERIOD ENDED 31 DECEMBER 2024 (Amounts expressed in Turkish Lira (“TL”) unless otherwise indicated.) Çelebi Ground Handling 2024 Annual Report 2.6.18 Taxes on Corporate Income Current Tax Expense and Deferred Tax Tax expense includes the current tax expense and deferred tax expense. Unless it is related to a transaction that is directly recognized in equity, tax is included in the income statement. Otherwise, the tax is also recognized in equity along with the related transaction. Current tax expense is calculated based on the tax laws applicable in the countries where the Group’s subsidiaries and equity- accounted investments operate as of the financial position statement date. Income Tax The Company and its subsidiaries, affiliates, and jointly controlled entities within the scope of consolidation, which are incorporated in Turkey and other countries, are subject to the tax legislation and regulations applicable in the countries where they operate. In 2024, the corporate tax rate in Turkey is 25% (2023: 25%). The corporate tax rate is applied to the net corporate income, which is determined by adding non-deductible expenses according to tax laws and deducting exemptions and allowances stated in tax legislation. Corporate tax must be declared by the evening of the 25 th day of the fourth month following the relevant fiscal year-end and paid by the end of the same month. Additionally, under Turkish tax regulations, companies with legal or business centre’s in Turkey are required to calculate provisional tax on their quarterly financial profits and declare the relevant period’s results by the 14 th day of the second month following the period, paying the calculated provisional tax by the evening of the 17 th day. The provisional tax paid within the year is offset against the corporate tax calculated on the corporate tax return to be filed in the following year. If there is any remaining provisional tax after offsetting, it can be refunded in cash or used for future tax payments. As of 31 December 2024, and 2023, tax provisions have been recognized in accordance with the applicable tax regulations. According to the Corporate Tax Law, tax losses reported on the tax return can be deducted from corporate taxable income for up to five years, provided they are not carried forward beyond this period. Declarations and relevant accounting records are subject to review by the tax authorities within five years. Dividend payments made to entities other than those exempt from corporate and income tax in Turkey, as well as payments made to Turkish and non-Turkish resident individuals and non-resident legal entities, are subject to a 10% withholding tax. However, dividend payments made by resident companies to other resident joint-stock companies in Turkey are not subject to withholding tax. Additionally, no withholding tax is applied if the profit is retained or added to the capital. Turkish tax legislation does not permit the parent company to file a consolidated tax return, including its subsidiaries. Therefore, the tax liabilities reflected in the Group’s consolidated financial statements have been calculated separately for each company within the consolidation scope. Deferred Tax Deferred tax is calculated using the liability method on temporary differences between the carrying amounts of assets and liabilities in the financial statements and their tax bases. The tax rates enacted at the financial position statement date under the prevailing tax regulations are used in the calculation of deferred tax. While deferred tax liabilities are recognized for all taxable temporary differences, deferred tax assets arising from deductible temporary differences are recognized only to the extent that it is highly probable that taxable profits will be available in the future to utilize these differences. Deferred tax assets and liabilities are offset only if there is a legally enforceable right to offset current tax assets against current tax liabilities and if they relate to income taxes levied by the same taxation authority within the same jurisdiction. As of 31 December 2024, a tax rate of 25% has been used in the calculation of deferred tax for all temporary differences. Turkish tax legislation does not permit the parent company to file a consolidated tax return, including its subsidiaries. Therefore, the tax liabilities reflected in the Group’s consolidated financial statements have been calculated separately for each company within the consolidation scope. In the financial position statements dated 31 December 2024, and 2023, the tax amounts payable for each subsidiary have been netted off and are presented separately in the consolidated financial statements.
