What does it mean to make up the social security gap?

Legal analysis: social security difference: refers to the difference between the declared social security base and the average social security payment base announced by the Social Security Bureau that year; For example, when the average social security payment salary was 2000 yuan, and the enterprise declared 1980 yuan, then as long as the employees who are on-the-job insured, each person needs to pay the difference of 20 yuan every month.

Legal basis: Article 86 of the Social Insurance Law of People's Republic of China (PRC), if an employer fails to pay social insurance premiums in full and on time, the social insurance premium collection agency shall order it to pay a late fee of five ten thousandths per day from the date of default; Failing to pay within the time limit, a fine of more than one time and less than three times the amount owed by the relevant administrative departments shall be imposed.
