The company pays back the social security, and the individual part can only be borne by the individual.

If you participate in the insurance in an individual's name, if you miss the payment, you cannot make up for it. Only the missed payment caused by the unit can make up for it and pay it back.

The individual's payable portion should be calculated by the Social Security Center, and then handed over to the unit's finance by the individual, and the Social Security Service Center will uniformly deduct the payment from the unit's account.

1. How does the unit make up the previous social security payment? 1. When the enterprise handles the social security backpayment business for its employees, it needs to import the insured person information from the social insurance agency or online service receipt into the "Social Insurance Information System Enterprise Management Subsystem"

2. Then the enterprise enters the details of social security supplementary payment through the system; 3. Then exports and prints and stamps the "Social Insurance Supplementary Payment Details Form" and "Basic Medical Insurance Supplementary Payment Status Form" in triplicate, and finally makes the supplementary payment.

Declaration; 4. After passing the application, social security contributions can be made for employees.

Enterprises can only make up for the social security contributions that employees have made within the past three months due to job changes and other reasons. If the amount exceeds this standard, they need to find a professional social security payment agency to make up the payments.

2. Social security supplementary payment means that due to some reason, social security payment is interrupted, and there is no payment in the intervening months. Now, due to recruitment or other reasons for settlement, it is necessary to make up the part that was not paid before, so as to obtain a complete social security period.

To ensure the normal approval of recruitment, transfer, settlement and other work.

Under normal circumstances, general units can only make back payments for 2 months. If it takes longer, it can only be done through some agencies.

The social security policy allows for up to two years of repayment, which means that it is calculated from the month of repayment. It is calculated based on the time period of the repayment, not the cumulative months.

The supplementary payment of social security is the part that is terminated after the social security application is started, and cannot be supplemented forward.
