Short diary, I don't know how to link. Romney has decided to use a Federal Blind Trust if elected. Typically, this is a yawn ... a no big deal story. However, just like Dick Cheney, Romney will avoid paying massive capital gains taxes by using a Federal Blind Trust
The law has a provision that allows the "deferment" of capital gains on any assets that are sold to comply with the rules of a Federal Blind Trust. Thus, if we are unlucky enough to have him as our President, all of his ownership and assets from Bain Capital will be sold. Rather than paying Capital Gains now, his tax basis in the stock the Trust purchases will be reduced by the deferred Capital Gains. The net effect will be an avoidance of taxes and if he continues to own the same stock until he dies, he will completely avoid ever paying any Capital Gains taxes. This could save him perhaps 30 million in taxes.
Hopefully, some other smart people on this site can fill in the gaps in my knowledge.
