I had a post about this awhile ago... I'm planning on claiming them on my 2004 taxes. I don't think you need the receipts and *&^% unless you're audited, in which case I think all the proof I need is online--in fact, I don't think I have a single physical receipt.
strictly speaking you never need proof (receipts) unless you are audited.hell, you don't even need to keep copies of your returnBut I still don't think these are allowable deductions.But for those who have already filed and did not deduct and want to deduct, you can always file an amended return.
when in doubt deduct. then you can just pay it back if you are audited.
