Donations of appraissed items is under IRs scrutiny right now because people were getting jewelry etc appraised for much higher than the are worth, cars same thing, so IRS expects proof otherwise you can only deduct reg fee from what I understand, unless you bought it for higher then the higher price is OK, like if you bought a domain for 10k and donated it you could take the full 10k deduction. I am not a tax expert just saying I would be carefull because if audited you have to prove its worth and domain appraising isnt a science, same as antique appraissals which irs is after those folks too. people buy antiques for little and get a high appraissal for the item and some of them have lost there battle with irs and made them change the deduction to what they paid for the item. Like i said i am not a tax expert but have read on little on the subject, also curious what other more qualified people have to say. I would aslo think if you had evidence of a money making name then you could figure that in the equation.
