What does Celery do with the 'personal contribution' field in taxed fringe benefits like the company car and phone?
In case the employee is paying an own contribution for the company car, phone, house etc. you have to enter this amount in the 'personal contribution' field.
In that case the taxed fringe benefit amount will be decreased with the personal contribution. If the contribution is more than the taxed benefit, the taxed benefit will be set on nil.
Entering the personal contribution field is not the same as actually deducting the own contribution. So if the employee has to pay an own contribution you have to create a wage code so you can add this code to the employee and deduct the own contribution.
