This- your 1099-B's will be reported to the IRS and occasionally they don't receive the basis. If you don't report your own basis- they will assume it was $0 and they'll try to charge you as if the proceeds are 100% gains. 
  
 Unfortunately - tax people normally charge extra for each form so even if you broke even (or had a loss) your going to be paying extra for them to file the return.

Seriously. I was quoted about $300 to file and I hadn't made enough to even owe. So I just didn't file and left the taxes I paid from working part time (less than filing would cost) on the table.
