This is worthy of The Guardian. Which did, in fact, make this mistake just recently:
Buybacks, where companies spend money repurchasing their own stock and making it scarcer, are emblematic. They are a more tax-efficient way of returning money than dividends, which incur capital gains.
T’other way around, buybacks pay CGT, dividends income tax….. of course, here it’s infelicitous phrasing, The G actually got it wrong, but still.
