Senior executives can, after a fashion, get a portion of their pay tax-free. You defer part of your income and not have to pay taxes on it, and then when you retire you have the company buy a life insurance policy on you using that money. The company can deduct that money because it is a business expense, and the money will get paid out to your children or grandchildren when you die, so you have effectively given them your money and it's never been taxed.
