This is pretty common when someone has a lot of cash that is liable to capitol gains. If you sell the assets to the pat you can pay the taxes over time on the money that is distributed instead of paying the capitol gains all at once and loosing that earning power. You do loose the money in that it you cant use it but you make more money in the long run because you spread the taxes out and make money on the potential…
Careful. Taxes in the US are pay-as-you-go. You can't just "pay the tax man in April." Well, you can, but you also have to pay him the penalty for failing to pay throughout the year. See http://www.irs.gov/taxtopics/tc306.html .
(I personally ended up with a 2011 tax liability that was something like 160% of my 2010 liability, but I'd paid estimated taxes equal to my 2010 liabilities. So I had to cut the IRS a pretty big check in April, but had no penalties.)
