Jinan social security salary cannot be declared.

Hello, it depends on the actual situation:

1. If you are older, close to retirement age, less than 15 years, it is recommended to find a professional institution to make up for it.

2. If you are still young, I suggest you continue to pay social security directly in your unit or professional institution, and you don't need to pay back. Social security is cumulative. The more years you pay, the more you get, but the proportion is different, which does not affect.

3. The above answers are provided by Jinan Dinghe Manpower. If you have any questions, please consult Jinan Dinghe Manpower.
