Same day NSO exercise , no 1099B filed

[AdelM]

I exercised some company stock options last year, same day cashless sale. The result of the sale is all ordinary income (0 capital gain/loss) and is reported by my company on my W-2 box 12.

The broker did not file a 1099B for this transaction (I guess not required in this case). I'm confused if I need to report the sale on Form 8949 or not, it doesn't change the taxes amount either way. Am I required to file form 8949 for this or will it cause more issues since the transaction is not reported ?

Yes, report the transaction.  While you indicated that you exercised the option, it also appears that you sold the stock that you purchased.  While you have neither a gain nor loss, and even though it was not reported on a 1099-B, you can report the transaction on Form 8949 and your purchase price and sale price will be the same resulting in no gain/loss.

Thanks @GeorgeM777 for the response, it was really helpful ! I entered the information on Form 8949 and everything looks good.
