This ZATCA guide clarifies the domestic tax treatment for cross-border software payments under the KSA Income Tax Law. It provides ZATCA's official position on classifying income from various transactions, including copyright transfers, licensing, distribution, and software development. The guide categorises payments as royalties, capital gains, commercial profits, or technical services to determine the correct withholding tax (WHT) application. It analyses numerous transaction types with practical examples, offering crucial guidance for non-residents receiving payments from KSA, ensuring compliance with domestic regulations rather than Double Taxation Agreements (DTAs).
