Social security units need to pay a positive difference.

The subject wants to ask, "Does the social security unit need to pay for the positive difference?" No need. The Ministry of Human Resources and Social Security inquires according to social security payment policies and regulations, and generates payment base adjustment and reimbursement balance in batches. If the difference is positive, the employer will repay the difference. The social insurance plan is organized by the government, forcing a certain group to use part of its income as social insurance tax (fee) to form a social insurance fund. Under certain conditions, the insured can get fixed income or loss compensation from the fund. It is a redistribution system, and its goal is to ensure the reproduction of material and labor and social stability.
