So you have to pay 90% of your the current years tax liability or 100% of last years tax liability (or 110% if you make over 150k) or otherwise you get hit with a 20% penalty (additional tax) on your underpayment. Im guessing that since first owns his own business his accountant has him make 100% or 110% (if first makes over 150k) tax payments based off of last years income taxes.

So i guess techniqely Obama is returning more of his money, but only because he earned less money and therefore doesnt have to pay as much taxes. Apparently when you own a small business your income isnt guaranteed (where are you Obama?) and you can actually make less money, no money at all or even LOSE money......
