Is it illegal for private enterprises not to pay social security?

Legal analysis: illegal. First, if the company fails to pay social security, it can ask to pay social security. Second, if the company does not sign a contract, it is also illegal. You can ask the company to pay double wages and not sign a written labor contract. Third, if the company terminates the labor contract illegally, it will also bear compensation, and the standard of compensation is twice that of economic compensation. If an employee resigns, he may ask the unit to pay economic compensation. Fourth, if you have worked in the company for one year, the company has to pay unemployment insurance. Fifth, if the company has overtime behavior, it should pay overtime wages and extra compensation according to legal standards.
