<prompt> Human: So Ive worked for this company for almost 2 years now intern for summer of 2015 and 2016, full time as of January 2017. As part of their benefits program, they match 100 of the first 3 invested in a regular 401k retirement fund. It turns out the HR rep didnt transition me properly from part time to full time status when they officially hired me in January 2017. So I was never enrolled into the 401k fund until now 4 months later. I havent had the 3 pre-tax deduction from my pay, but Ive also missed out on any 401k company matching. Do I have a case to ask for the money Ive missed out on? I would need to pay back 3 of my net income over the last 4 months to have a chance at seeing the 3 matching from the company...but this money has already been taxed so Im confused if this is even feasible.Assistant: Youll need to read the plan regarding auto enrollment and plan entry. If the plan does not have auto enrollment, it is your fault for not signing up for deferrals and you will have to live without that match. If the plan has auto enrollment, figure out when you should have been auto enrolled based on the plan rules. If they were late with the auto enrollment, you may have a case for a qualified non elective contribution where your employer owes you for what was missed.Human: I was enrolled to have auto-deductions starting middle of February, which is consistent with what the HR person told me on my first day. She said the company automatically puts 3 away starting in February so I can take advantage of the company matching as soon as possible. This setting couldnt take effect because I was still in their database as a part time employee.  <response>: If they told you that you had been auto enrolled then they should be able to honor it retroactively. I would ask nicely and see what theyre able to do
