Our company has set up a new 401K Safe Harbor Plan. They contribute 3% regardless of employee contribution. Employees are allowed to choose a flat rate per check or a percentage per gross pay. Do I need to set up two different Deducts with one being for flat rate & other for % ? Also if one employee chooses 3% while another choose 6% what formula would I use and where would I be able to enter the percentage for each individual selection?
