<prompt> Human: Hi,So like the title says, in 2016 I rolled a 401k from a former employer over.I took the 401K from the former compan and moved it over to an investment company that currently holds some of my investments with the idea that they would manage the 401K along with my investments.When they told me the fees that they would take for managing this, I decided to then move the funds to the 401K that I have with my current employer - why pay fees twice?.So then yesterday the IRS sends me a letter saying that that rollover was income that I did not report and I owe over 10K in taxesinterestfees.Clearly this is just a misunderstanding andor mix-up in how things were processed, but I have no idea about how to proceed in getting this resolved.Thank you!!Assistant: Sounds like maybe the old 401k was cashed out and reinvested, rather than rolled over..? Human: Trying to figure out who to call to help figure it out , I just did what the finance folks I worked with told me to do Assistant: Can you explain the steps you took to do this double rollover? Did you at any time get a check in your hand made out to you to deposit into the new 401k?Also, is 10k the total amount that had been in your 401k that you rolled over?Human: This. If you got a check, I think it was a cash out. Assistant: this cannot be so, they explicitly told me to do this  <response>: The bigger issue isnt even the check...Im more concerned that you say you took a 401k which is usually pre-tax and put it into a Roth IRA which is post-tax. If thats what you did, you would owe the taxes because you converted it to a post-tax retirement investment.
