1099s are SUPPOSED to be in the recipient's hands by 1/31. They may be 'corrected' after that and reissued. I am expecting a bunch from different companies and just received my first one today.
So my first one is "wrong" by $400+ until I realize 1) mileage reimbursement is treated as a 'bonus' by this company and 2) It includes all 2011 income + a payment from 2010 that fell 'in the cracks' at the company. Once I make these adjustments, the 1099 is off by $4.92. I am NOT going to lose sleep over it!
