The insurance premium calculation is based on the actual insurance coverage days if the insured persons enroll or withdraw during the month. For those who adjust their insured salary, the changed insured salary is effective and used in calculating insurance premium from the first day of the next month after the insured salary adjustment table reaches the Bureau of Labor Insurance. If the insured unit follows the above rules to deduct insurance premium, the amount should be the same with those calculated by the Bureau of Labor Insurance. If there is any differences, please pay the amount on the paying-in slip first and check whether there is any error on the “list of modifications to the information of insured persons and insurance premium calculation in the month” and then ask the Bureau of Labor Insurance to check. If there is any errors found after the check, the insurance premium will be adjusted and corrected in the next month’s paying-in slip.
