Can the social security base be changed if it is wrong?

The social security base is wrong. As long as the payment has not been made, you can apply to the local social security agency for revision. You need to fill in the social security base change form and get the approval of the social security agency. However, if the payment has been made, it cannot be changed this year, and it is necessary to wait until the social security base is adjusted the next year before applying for revision. You need to submit employee social security base declaration form, employee salary certificate for the same period, company guarantee and company official seal.
