Which jurisdictions tax unrealized capital gains? Asking for a friend so I can avoid passing through.
I doubt this is a common thing. Whereas the other case (dividends tax credit) is far more common. It impacts those of us in Canada. Our government disincentivizes buybacks and encourages dividends instead. Typically, if you're in a low income bracket, and have investments brewing for decades (with high amounts of unrealized gain) in an unregistered account, it is preferable to get dividends over buybacks.
If you buy regular stocks in a regular brokerage account, you do not incur taxes before selling (with profit).
Same for dividend-distributing ETFs.
