<prompt> Human: My husband and I filed our taxes in early February and have already received our refund. Today in the mail he got a 1099-B for investment profits of 0.89. We are going to amend our return since it wont cost us anything but, is it even likely to make any difference?Edit: the title should say if, sorry.  <response>: The tax due on the 89c will be between 0c and about 25c, so effectively no difference and really, no need to amend.
