Annual compliance for Liaison Offices (LO), Project Offices (PO), and Branch Offices (BO) of foreign companies in India is essential to maintain their legal status and operational legitimacy. These entities must file the Annual Activity Certificate (AAC) with the Reserve Bank of India (RBI) and submit audited financial statements and annual returns with the Registrar of Companies (ROC). Compliance also includes adherence to tax regulations, transfer pricing norms, and maintaining proper books of accounts. Non-compliance can lead to penalties, restrictions, or cancellation of licenses. Regular and accurate compliance ensures smooth operations and legal protection for the foreign entity in India.
