employee stock roll over to a brokerage account and a cost basis

[Redsdad]

I rolled a 401k account to a Fidelity brokerage account to get the NUA - net unrealized appreciation treatment and I received a 1099-R showing the total dollar amount and the "taxable amount" called the "cost basis" on the rollover from the 401k side of Fidelity . The bulk of shares is still there. Then sold some shares to get cash. Fidelity (individual brokerage acct) sent a 1099-B showing the shares I sold and the proceeds with the wrong "cost basis" and can't get it corrected because no one there seems clear after six calls. I have the "taxable amount" from the 1099-R and the number of shares SOOO How do I figure the right cost basis for the 1099-B I have? IS the taxable amount on the 1099-R the same as the "cost-basis" on the 1099-B? Is it figured per share or do I just plug in the entire amount?  There is a place to correct it but I have to put in the right number. Thanks!

To be sure I understand.  You withdrew your 401-K and put it into a Brokerage account.  If that is true:

You should report the 1099-R.  That will bring you up to the point where you cashed out your 401-K.  At that point each individual fund will establish a new basis on the day of the transition. 

So you will have to get the value of the stocks or funds that you sold on the day of the transfer, and that will be your basis.  You will have to have this for everything in your portfolio, so you can start on that now.

Thanks for you Help first of all! But to make sure I understand, When I rolled over My 401k the taxable amount I am reporting from a 1099-R - got it. But, the "cost basis" from the Brokerage account is actually the value of the stock on the day of Rollover? i.e. rolled over $100,000 = 1000 shares x 100. So the cost basis would be 100,000, is this right? Thank you very much!

Based on the example you posted above, the 1099-R should reflect the $100,000, and you will pay tax on that.  If that is true the 1000 shares would have a new cost basis of $100 going forward.
