Sixty years ago, present management took control of Berkshire. That move was a mistake – my mistake – and one that plagued us for two decades. Charlie, I should emphasize, spotted my obvious error immediately: Though the price I paid for Berkshire looked cheap, its business – a large northern textile operation – was headed for extinction.

The U.S. Treasury, of all places, had already received silent warnings of Berkshire’s destiny. In 1965, the company did not pay a dime of income tax, an embarrassment that had generally prevailed at the company for a decade. That sort of economic behavior may be understandable for glamorous startups, but it’s a blinking yellow light when it happens at a venerable pillar of American industry. Berkshire was headed for the ash can.

Fast forward 60 years and imagine the surprise at the Treasury when that same company – still operating under the name of Berkshire Hathaway – paid far more in corporate income tax than the U.S. government had ever received from any company – even the American tech titans that commanded market values in the trillions.

To be precise, Berkshire last year made four payments to the IRS that totaled $26.8 billion. That’s about 5% of what all of corporate America paid. (In addition, we paid sizable amounts for income taxes to foreign governments and to 44 states.)
