Dear Dear, I am happy to answer your questions about how to make up the difference in the social security base: There are generally two ways to make up the difference in the social security payment base: online or on-site. Taking Guangdong Province as an example, the procedures for making up the difference in the social security payment base are: 1. Online payment 1. Log in to the "Guangdong Local Tax Electronic Tax Service Office (Electronic Taxation Bureau)"; 2. Tax processing; 3. Social security fee management; 4. The "Enterprise Pension Insurance Balance Back Payment Declaration" module performs back payment declaration and deduction operations. 2. For on-site repayment, go to the front desk of the local tax department with the "Application Form for Repayment of Enterprise Employee Pension Insurance Premium Difference" (hereinafter referred to as the "Application Form"). The "Application Form" can be obtained through the following channels: online reporting units can download and print through the Foshan online reporting system, and regular quota households can collect it at the front desk.

That’s it
