Landless farmers pay social security in one lump sum.

Legal analysis: Land-expropriated farmers who choose to participate in the basic old-age insurance for urban and rural residents or the basic old-age insurance for enterprise employees can enjoy the old-age insurance subsidies for land-expropriated farmers. The basic old-age insurance premium paid by land-expropriated farmers shall be paid from the old-age insurance subsidy funds first, and the old-age insurance subsidy shall be borne by the individual after it is used up. Land-expropriated farmers who have received basic old-age insurance pensions receive old-age insurance subsidies at one time.

Legal basis: Article 74 of the Social Insurance Law of People's Republic of China (PRC), social insurance agencies obtain information needed for social insurance work through business handling, statistics and investigation, and relevant units and individuals shall provide it in a timely and truthful manner. The social insurance agency shall establish a file for the employer in a timely manner, completely and accurately record the social insurance data such as personnel's participation in social insurance and payment, and properly keep the original vouchers for registration and declaration and accounting vouchers for payment and settlement.
