Article 12(4) of the India-US Double Taxation Avoidance Agreement (DTAA) pertains to the taxation of fees for technical services. It defines the scope and taxation rights of both countries concerning payments made for managerial, technical, or consultancy services. This provision is significant as it helps determine the tax liability on cross-border service transactions between India and the US. Under this article, fees for technical services are taxable in the country of residence of the recipient, but may also be taxed in the source country at a specified rate, subject to certain conditions. The article aims to prevent double taxation and provide clarity on the tax treatment of such fees, ensuring that businesses can operate with a clear understanding of their tax obligations. The burden of proof typically lies with the taxpayer to demonstrate that the services qualify under the DTAA provisions.
