I cant blame you at all. When you get a 1099 for say $10,000 so does the IRS, even if you have all the documentation that says the prize was worth less. I claim the $10,000 because if you dont you could be setting yourself up for a tax audit! There is no way I want anything to do with that, I mean really who wants to deal with the IRS - not me baby. So I dont enter for so many things like trips and such because of the high value they usually claim.
Actually, the IRS addresses this issue. They state that first you can request the sponsor change the value to the correct value. We did this on a trip prize once. If the sponsor refuses to change it, you can, at your option, fill out a form the IRS has to have them force the sponsor to change the value. Either way, backup documentation is proof enough for the IRS. We have never reported the full value on 1099's that were not readjusted. That would be like paying taxes on income you never got. :nono: :)
