This is a common issue but we wanted to ask if there is anything we can do to stop an employee's contributions at the correct limit when they come to us having already contributed to a 401k with a previous employer during the year. We are a % based plan, so we usually just have them estimate how much they can contribute each pay period. If there is a way to establish a limit just for them based on previous contributions it would be very helpful. Thanks in advance for your thoughts!
