I'm not trying to be obtuse, I'm genuinely curious how this would work and what changes to tax law would need to be made.
Would you tax the entity buying the stock (in case always a company since it's a buyback; which I think would be the only example of taxing a stock purchase), or the entity selling the stock (either an individual or a company, which is already potentially taxed as capital gains)?
If the goal is to tax it similar to dividends you would tax the person selling the stock but it's already taxed as capital gains, either long term (0%/15%/20%) or short term (marginal bracket rate).
