What if the old-age insurance is overpaid 100?

Contact the social security bureau or insurance institution, apply for refund or adjustment, and keep relevant evidence.

1. Contact the social security bureau or insurance institution: you can contact the local social security bureau or endowment insurance institution to explain the situation and provide relevant evidence, such as payment vouchers or transaction records.

2. Apply for refund or adjustment: You can apply for refund of the overpaid endowment insurance premium, or you can ask to adjust the overpaid part to pay later.

3. Keep relevant evidence: When dealing with such problems, you must keep relevant evidence documents, such as payment vouchers and refund application records.
