The date of resignation does not affect the social security processing.

Legal analysis: Resignation after 15 will not affect social security and provident fund. General units will take no. 15 is the dividing line. Did the employees who joined before 15 pay the social security of the current month, but the employees who joined later did not. 15 did not pay social security in the current month. Employees who leave before 15 will not pay social security for the current month, while employees who leave after 15 will pay social security for the current month.

Legal basis: Article 58 of the Social Insurance Law of People's Republic of China (PRC) stipulates that the employer shall apply to the social insurance agency for 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.
