Hello, excuse me, the salary base of social security contribution is 2390 yuan, so how much should I fill in the monthly salary?

Refers to the average monthly salary of the insured person in the previous year. If today's date is July 20 12, 19, and the current payment year is 20 12 (April 2065438 +0 1 March 2008), then the payment wage base of this year is the insured's previous year (that is, 2065438) For example, the total pre-tax salary of the insured in the previous year was 60,000 yuan, and the average monthly salary was 5,000 yuan. So the "average monthly salary for determining the payment base" you need to fill in is 5000 yuan.
