There are two recent cases where Warren has done everything possible to AVOID paying taxes that he actually owes.... The second case is still pending after 10 years in which he owes just over $1 BILLION in back taxes... Then there is the recent deal involving the Bank of America. US corporations are subject to a top federal income tax rate; the second highest in the world. But Berkshire wont pay anything close to that ... Please note that this article is NOT dissing Warren about using every available option to minimize taxes. That is the only sane approach any individual would take.
