Social Security deductions twice what happened, here's why

Social security deductions twice how to do things, the reasons are as follows, the following with me to briefly understand it.

Social security deductions should be only once a month, but if there are two deductions, it may be the following:

1. There may be a retroactive deduction of the previous period should be paid without payment, the bank system will not be an error, but it is best to consult with the operator or social security institutions specifically.

2. Each year, the beginning of the social security in accordance with the tentative contribution base payment, wait until November or December after the provinces announced the official contribution base, such as before the tentative base in accordance with the 3800, the back of the announcement of the official base of 3900, will be deducted for the part of the less deducted additional deduction, which is the most common reason for the month of the deduction of the two social security.

3. If it is last month, according to the rules of social security accounting, the month of insurance next month to produce the month and the next month two months of costs, which is a relatively common phenomenon.

4. The participant's withholding bank card may have been used to withhold social security payments from family members in addition to his or her own.

5. If the unit has made a second deduction, the employee asks the unit's personnel to see if duplicate payments have been made, and can ask the personnel to make a refund to the Social Security Administration.
