Can social security be replenished five years ago?

Legal analysis: social security can be paid back for one year. As long as you pay the late fee according to the regulations, you can pay it back. You must have a company to repay the previous month. The company signed a labor contract with you, and there is a payroll for paying wages. If you don't pay within the term of the labor contract, you can ask the company to pay. The refund is based on the salary paid by the company.

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.
