Is it legal for the company to pay social security in other places? If it is an independent accounting subsidiary with a business license and code certificate, it should only register social security in the place where the subsidiary is located in Hunan and participate in insurance according to law, not in Shenzhen. According to the provisions of Article 57 of the Social Insurance Law of the People's Republic of China: "The employer shall apply to the local social insurance agency for social insurance registration with its business license, registration certificate or unit seal within 30 days from the date of establishment." Therefore, social insurance is subject to territorial management. Is this easy to understand?
