A Subsidiary Company Registration allows a parent company to create an independent legal entity under its control. Although it functions autonomously, the subsidiary adheres to the strategic direction of the parent firm. It has advantages including less responsibility, tax advantages, and simpler market expansion and can be owned entirely or in part. Choosing a business structure, getting the required permits, and abiding by the law are all part of registration. Businesses can expand while controlling risks and preserving operational and financial flexibility with the support of a properly established subsidiary.
