Read an idea in American Affairs in support of taxing buybacks. The logic goes that if all companies have a fiduciary duty to shareholders because the market is the most efficient capital allocator, AND all companies are giving their cash back to shareholders, THEN it must be true that the market can not figure out how to efficiently allocate this $1T of capital. Thus, the government should have “next dibs” for items…
At the very minimum it should be taxed the same as dividends. Essentially tax buybacks are a tax loophole for giving money back to the shareholder.
The right answer isn't to introduce new forms of buyback taxes with unknown second-order effects (who would you tax? if the shareholder is avoiding dividend taxation, taxing the corporation isn't a great solution). The solution is to just improve the way we tax dividends and capital gains.
