The newly established company in Shanghai runs the social security process for the first time.

1. The newly established unit shall, within 30 days from the date of obtaining the business license or approving the establishment, go through the insurance account opening formalities at the social security agency in the jurisdiction where the local tax relationship is located, and bring the original and photocopy of the industrial and commercial business license or the original and photocopy of the approval document for the establishment of institutions and institutions, and the legal person certificate of institutions; Original and photocopy of the certificate of unified code of the organization; Original and photocopy of local tax registration certificate (non-taxpayers may not show it); The Social Insurance Registration Form stamped with the official seal and the Form for Determining the Industry Risk Level and Expenses of the Units Participating in Work-related Injury Insurance; Original and photocopy of legal person's ID card.

2. The social security department shall review the data, go through the registration formalities for new insurance, and print the social insurance registration certificate.

3. After the new insurance registration of the unit, handle the new insurance registration of employees, and pay social insurance premiums to the local tax department on a monthly basis from the next month.

Have obtained the relevant certificates of the unit, take the originals and photocopies, and then collect the materials of the employees of the unit: a copy of the contract, a copy of agricultural registered permanent residence (unemployment insurance benefits and agricultural registered permanent residence don't have to pay 1% of the payment base), an original second-generation ID card (or an electronic registration photo or a one-inch red background registration photo), a copy of the second-generation ID card and a copy of the payroll (used to check whether the salary of employees is lower than that of the previous year in Shanghai, not lower than that of the previous year).

That's all I can think of. You can go to Shanghai social security related network to check. There are guides and forms available for download online, which vary from place to place. We all inquire, download and handle in Wuhan on the "Wuhan Labor and Social Security Service Network". Shanghai also has it.
