Can social security be renewed after a year off?

Yes Social security can be paid after a year off. After the interruption of social security, the previously paid social security will not be cancelled, cleared or invalidated, and will remain in the account, but the medical insurance reimbursement and endowment insurance will be affected by time. Among them, the endowment insurance is calculated cumulatively, not continuously, so even if the payment is suspended for a period of time, you can choose to continue to pay later. If the medical insurance premium is interrupted for more than three months, the payment period will be interrupted, and the previous payment period cannot be calculated continuously, starting from the time of re-payment. At the same time, from the month when the payment has never been made on time, the medical insurance benefits will be suspended.
