The unit has handled the increase of social security, and the individual has not handled the transfer procedures in different places. In that case, will the unit deduct the money?

You have to take this admission notice to the original social security bureau for social security transfer, and social security can be transferred to the receiving social security bureau. If you don't do it, even if you open the admission notice, you won't transfer.

And did your new company file your labor contract and apply for social security? If you have declared and applied for social security, the social security bureau will deduct the social security fee from the month you declare. For example, your contract will be filed in July, and social security will be completed in August. The social security bureau will also deduct money from July, regardless of whether your social security is transferred.

If the new company has already done it for you, then you'd better transfer it to the original social security, so your social security period will be calculated together. For example, you paid 15 years in three years, and now you can pay 1 1 year. If you don't transfer, you have to pay 1 year from the beginning.
