The Relationship between Personal Income Tax and Social Security in Beijing

A person can only establish a labor contract relationship, so social security can only be paid by one company for you. However, the taxable income of withholding tax is not only the remuneration of labor contract. For example, you work in company A and pay social security in company A, but your income is less than the tax threshold, so you actually didn't pay a tax in company A. You created a literary work in your spare time and authorized it to company B to get remuneration. Company B withheld and remitted personal income tax for you when paying remuneration according to law. In this way, you actually pay personal income tax and social security in the name of two different companies. If your question refers to whether you can pay personal income tax and social security in the name of two different companies, then the law stipulates that you can't, but there are many situations in practice. For example, some lawyers work in enterprises, but the lawyer's certificate is hung in the law firm. If the enterprise management is not standardized, he can pay social security instead of the enterprise in the law firm.

The above is an introduction about whether Beijing can pay taxes and social security in two companies.
