Upon reviewing your private letter ruling request form, it has been understood that, as stated in your articles of association published in the Trade Registry Gazette, your Company provides all kinds of engineering and technological services, including thermodynamic, thermal, and fluid mechanics analysis, both domestically and internationally. It has been noted that you provided engineering services to … GmbH Co. KG located in Stuttgart, Germany, and that you issued invoices exempt from VAT for the services provided to projects abroad. You have requested a ruling on whether 80% of the income derived from this service provided abroad can be considered as a deduction in determining your corporate tax base under the provisions of Article 10, paragraph 1, subparagraph (ğ) of the Corporate Tax Law.

In the first paragraph of Article 3 of the Corporate Tax Law No. 5520, it is stated that institutions listed in Article 1 of the Law, whose legal or business center is located in Türkiye, will be taxed on all the income they obtain both within and outside Türkiye. Furthermore, it is stipulated in Article 6 of the same Law that corporate tax will be calculated based on the net corporate income obtained by the taxpayers during an accounting period, and the provisions of the Income Tax Law regarding commercial income will apply in determining net corporate income.

In the first paragraph of Article 10 titled “Other deductions” of the same Law, deductions that can be made from corporate income, provided that they are additionally indicated on the corporate tax return, are included. In subparagraph (ğ) of the first paragraph of the mentioned article, it states: “Income obtained by service businesses that provide architecture, engineering, design, software, medical reporting, bookkeeping, call center, product testing, certification, data storage, data processing, data analysis, and services provided under the permission and supervision of the relevant ministry in the fields determined by the Ministry of Finance, exclusively benefiting persons not resident in Türkiye and entities whose workplaces, legal and business centers are located abroad, provided that 80% of this income is transferred to Türkiye by the deadline for submitting the corporate tax return related to the period in which the income was earned (with the amendment made by Article 59 of Law No. 7491; effective for income and gains obtained from 1/1/2023 onwards on 28/12/2023).
