Can social security units pay after individual contributions?

Legal analysis: social security can be paid by individuals and then by units. Transfer the personal account to the company name to pay the fee. If there is a repeated payment month, it shall be handled according to the local social security regulations. If I pay the fee first, I can negotiate with the unit, and the unit will subsidize a certain amount. Or the unit calculates the number of months and the amount that the unit should pay and returns it to the party concerned.

Legal basis: Article 58 of People's Republic of China (PRC) Social Insurance Law. The employing unit shall handle social insurance registration for employees within 30 days from the date of employment. If the social insurance has not been registered, the social insurance agency shall verify the social insurance premium it should pay. Employees-free individual industrial and commercial households who voluntarily participate in social insurance, part-time employees who do not participate in social insurance in the employing unit and other flexible employees shall apply to the social insurance agency for social insurance registration. The state establishes a national unified personal social security number. Personal social security number is a citizen's identity number.
