Can I pay social security at 3000 for a salary of 6000?

You can't. The salary of 6,000 yuan cannot be paid social security according to the standard of 3,000 yuan, and the social security payment base is determined according to the average monthly salary of employees in the previous year. If the wages of employees are higher than 300% or lower than 60% of the average social wage, the payment base is limited to 300% or 60%, but between these two ranges, the payment base shall be determined according to the average monthly salary of employees in the previous year. Therefore, a salary of 6,000 yuan cannot be paid social security according to the standard of 3,000 yuan.
