How long can social security be replenished at a time?

Legal analysis: social security can generally be paid for nearly three months, but as long as the labor relationship can be proved, there is no limit on the number of years, no matter how long. To pay back social security, employees' files, old-age insurance manuals, application forms for paying basic old-age insurance premiums, labor contracts, salary payment details, etc. should be carried with them until the social security agency handles the payment. Social security should be paid after calculating the total expenses that should be paid according to the time of breaking off. As long as it is handed in, it will not be affected. If the payment of social security is interrupted for several months, the social security for these months should be paid in time, and a complete social security period can be obtained after the payment. (1) Bring relevant certificates and materials to the Social Labor and Social Security Bureau where the household registration is located to apply for supplementary social security; (2) Fill in the application for social security payment at the Social Security Bureau and submit it; (3) After the application is passed, you can pay social security fees (pension insurance and medical insurance).

Legal basis: Article 63 of People's Republic of China (PRC) Social Insurance Law. If the employer fails to pay social insurance premiums in full and on time, the social insurance premium collection agency shall order it to pay or make up within a time limit.

If the employer fails to pay or repay the social insurance premium within the time limit, the social insurance premium collection agency may inquire about its deposit account in banks and other financial institutions; And can apply to the relevant administrative departments at or above the county level to make a decision on the allocation of social insurance premiums, and notify their bank or other financial institutions in writing to allocate social insurance premiums. If the balance of the employer's account is less than the social insurance premium that should be paid, the social insurance premium collection agency may require the employer to provide guarantee and sign a deferred payment agreement.

If the employer fails to pay the social insurance premium in full and fails to provide guarantee, the social insurance premium collection agency may apply to the people's court for sealing up, distraining and auctioning the property whose value is equivalent to the social insurance premium that should be paid, so as to offset the social insurance premium with the proceeds from the auction.
