<prompt> Human: I started a part-time job in January of this year. I filled out a form for Roth 401k contributions, which they said they would match up to 4. I just discovered they havent been withholding any money, or matching. That is, nothing has shown up on my pay stubs. I plan to talk with HR about this. Has anyone encountered this before? Can I just ask them to take my next paycheck and put that straight into a Roth 401k? I plan to ask them to back-match what they would have, if they had been matching all along, as if they had opened it when I requested it. I have the signeddated form showing when I requested the matching. Will that hold any weight?Advice?  <response>: Do you qualify for the policy yet? At my firm, we have to work there for a certain period of time before we qualify to start contributing to the retirement plan. Its possible HR had you go ahead and fill out the form so that when you do qualify, they can begin the withdrawals.
