International Taxation
Cross-border transactions demand cross-border clarity.
In an increasingly globalised economy, businesses and individuals frequently engage in cross-border transactions involving foreign income, overseas investments, imports, exports, and international structuring. International taxation governs how such transactions are taxed in India and abroad, primarily under the Income-tax Act, 1961, relevant Double Taxation Avoidance Agreements (DTAA), and international tax principles.
At Calculus, International Taxation advisory is delivered with technical precision, regulatory foresight, and structured documentation—ensuring lawful tax efficiency while minimising cross-border risk exposure.
