I saw this in an article and was wondering if you could set me stratight; if you buy T-bills, notes bonds and savings bonds is that tax deductible?
When you write a check to the Bureau of Public debt that is also tax deductible, correct? Is this why Warren Buffet stated he would give 1 billion dollars to the gov?
That's only for contributions (i.e. donations) when you write a check to the Bureau. Buying something like T-bill and bonds don't count. See here
As for Warren, he's making a donation. And while I have no doubt that he'll take the tax deduction he's entitled to, that's not the reason for the donation. It makes no sense to give $1B away to get back $350M in taxes. That's a $650M loss. He's making the contribution because he believes that it's the right thing to do.
