If the company cannot deduct the fee due to the bank account number, it can go to the acceptance window of the social security agency for manual collection from the 23rd to the end of the month. If it is necessary to deduct fees in advance, you should bring the company information (stamped with the official seal) and the Commitment Letter of Deducting Fees in Advance (stamped with the official seal) to the acceptance window of the social security agency for manual collection.
