Using multiple deduction codes for one type of benefit
When you're assigning codes to your benefits in Zenefits, you can assign only one code to each benefit. For example, medical insurance in Zenefits can be assigned a code of "Medical 1" or "Medical 2", but not both at the same time. If you have multiple codes in payroll for the same benefit, you'll need to chose which one you want Zenefits to use, or create a new one.
Once you decide on a new code (or create one), you'll need to update the deduction mapping in Zenefits, and then either enter zeros for the older code or delete it from the employee entirely to avoid over-deducting them.
Thank you for the feedback!
