It leaves it out because it isn't relevant. Amazon pays no federal tax (or close to none anyway) but it pays a shitload in other taxes.

Amazon reinvests revenue into the business which is discussed tons on this site. It also has the effect of eliminating certain types of taxes... and massively increasing taxes in other areas (like sales, use, B&O, payroll, etc...). Somehow I don't see discussion of how payroll tax at Amazon is exploding, though.
