<prompt> Human: So I received my tax refund on february 27th. IRS accepted tax return. However I forgot to include stocks which is a net loss btw. Im guessing my brokerage didnt report their stuff until later? Is that why mine got accepted? Do I still need to amend?  <response>: That your return was accepted has nothing to do with your brokerage firm reporting. The IRS has literally billions of documents they receive every year. The process for matching them up takes awhile. Right now they are still sending out notices for 2015 returns that dont match the documents they received. Since you can claim a loss you should definitely file an amended return. Otherwise youre just leaving money on the table.
