It's is possible to process pension premium contributions in Celery. The base salary pension premium can be calculated in a number of ways. Sometimes 12.96 or 13 monthly wages are used as an annual basis. The AOV franchise is also often deducted. In Celery the settings for the pension premium are such that they will only have to be entered once. Any gross salary changes do not require manual adjusting or re-calculating of pension premiums. The pension premium will change if the gross salary is changed, which means that you can’t forget to adjust the pension premium in that case.
