How much can social security be refunded for more than one year?

Hello, to put it simply, the social security paid by you is stored in your personal account and can be taken out. The social security paid by the unit is twice that paid by the individual in the overall fund. You can't take this out until you retire. If you work in a company, you'd better pay social security. This is a guarantee for your future. If you have to take it out, you can only take personal parts. Not worth it. What the company pays for you will get back the fund, which has nothing to do with you. On the other hand, if you work in a company, the regular company will not agree with you not to pay. If it is found that the company's responsibility is relatively large, it will be repaid and fined. Moreover, if a work-related injury occurs, the company will compensate for the loss, so regular companies generally do not take this risk. If you don't pay, the company will let you leave. Of course, there are many informal units. If you don't pay them, the company will be happier and save a lot of money.
