That's exactly what I was looking for too. Anyone have info on putting a value on PC hardware? My best guess is that you wouldn't have any problems deducting the original price of the it (nice $3K deduction for that P/100 I bought in '95) but can anyone back this up or offer other advice?
First, I'm not a tax expert by any means, however my mom is, really she is (hi mom).
Second, the IRS allows you to deduct the FAIR MARKET VALUE, not the cost. The FAIR MARKET VALUE is the value that you would receive in an "arms length" transaction (not some deal between you and a buddy). You want an estimate of what PC equipment from 1995 is worth? Use Ebay as a basis - about 5 bucks plus shipping
Third, this thread was started with the intent to provide information for people to reasonably value their used items, not cheat the IRS. Don't undervalue what your deductions are, but by all means do not intentionally overvalue them either, that's the same as stealing. Won't get into the whole "government can afford it more than I can" discussion, hell the guy on the gold coast here in Chicago can afford more than I can to and it don't make it right to steal from him either!
Fourth... well, donating lets everyone win. You clear some space, get a nice reduction in your taxes, the less fortunate get a load of clothing, home appliances, etc. that they sorely need.
