Do provident fund and social security have to be in the same unit?

Legal analysis: you don't have to pay in the same unit.

The analysis is as follows:

1, social security and provident fund management institutions are different, the provident fund is managed in the provident fund management center, and social security is managed in Ministry of Human Resources and Social Security, so it is not necessary to pay in the same unit.

But a person can't pay two social security and provident fund at the same time. Even if there is, it is useless, because you can only enjoy one kind of treatment.

Social security and provident fund are paid in proportion to income. Generally, they must be paid at the same time, and they must be paid together to meet the legal requirements.

Legal basis: Article 3 of the Social Insurance Law of People's Republic of China (PRC) adheres to the principles of wide coverage, basic protection, multi-level and sustainability, and the level of social insurance should be compatible with the level of economic and social development.
