Can a farmer make a one-time retroactive social security payment?

Rural households cannot make a one-time retroactive contribution to their pension insurance.

When the new rural insurance system was implemented, those who had reached the age of 60 and were not entitled to basic pension insurance for urban workers did not have to make contributions and could receive a basic pension on a monthly basis, but their children who were eligible to participate in the insurance system should participate in the insurance and make contributions; those who were less than 15 years away from the age of receiving the insurance should make contributions on a yearly basis, or were allowed to make retroactive contributions, with a cumulative total of no more than 15 years of contributions; those who were more than 15 years away from the age of receiving the insurance should make annual contributions and a cumulative total of no less than 15 years of contributions. The accumulated contributions shall not be less than 15 years.
