I lost my social security for three months because I left my job.

If you pay back the social security for three months after leaving your job, I suggest you pay it back to the social security department immediately, so as not to affect your social security benefits. The specific operation steps are as follows:

1. arrears inquiry: inquire about your social security payment and arrears amount through the social security department official website or on-site consultation.

2. Payment of arrears: according to the query results, pay the amount of arrears in accordance with the regulations and ask the social security department to issue a payment certificate.

3. Complete information: After paying social security, you need to submit relevant materials, including personal identification, payment vouchers, social security registration forms, etc.

4. Confirm payment: After payment is completed, confirm payment with the social security department in time to ensure that the social security account has been updated.

In short, withholding social security after leaving the job will affect personal pension, medical insurance and other benefits, so take timely measures after finding problems to avoid adverse effects on personal interests.
