Legal analysis: the original tax registration certificate and business license need to be mounted and hung in the business premises. It is not illegal to carry a copy when going out on a business trip and fold the original. When showing the original tax registration certificate and business license to others, it will cause a bad image to your own enterprise. The main contents include: taxpayer's name, tax registration code, legal representative or person in charge, production and business address, registration type, accounting method, production and business scope (main business, part-time business), date of issuance, etc.

Legal basis: Regulations on the Administration of Registration of Enterprise Legal Persons

Article 25 The Business License of Enterprise as a Legal Person issued by the registration authority is a certificate of enterprise as a legal person, and no other unit or individual may confiscate, detain or destroy it, except that the registration authority may temporarily suspend or revoke it according to legal procedures. If an enterprise as a legal person loses its Business License for Enterprise as a Legal Person and its duplicate, it shall declare it invalid in the national enterprise credit information publicity system and apply for a replacement. The Business License of Enterprise as a Legal Person and its duplicate shall not be forged, altered, leased, lent, transferred or traded. The state promotes electronic business licenses. Electronic business license and paper business license have the same legal effect.
