The gap between pharmacies paying social security and units paying social security.

1. Different payment objects: pharmacies need to pay personal social security and taxes, and units pay social security for employees, with different payment objects.

2. Different payment bases: the social security base paid by units is wages or total wages, and the social security paid by pharmacies is personal business income.

3. Different payment proportions: the proportion of social security paid by the unit for employees is fixed, which is divided into the company side and the employee side, while the proportion and payment standard of social security fees that pharmacies need to pay social security are fixed standards.
