God, that seems horrible.
I don’t get taxes on index funds themselves - you don’t “own” anything - it’s basically a savings account that (in general) actually gives you something other than bajillions of a cent.
And there’s no sense in taxing you on what you already own (what you paid in). Especially on pension funds. Selling stock directly is a different matter, but that is done by the fund. They shouldn’t be passing this down onto you, nor should the government double-tax. Why don’t casinos charge capital gains when you cash out? Or stores charge you for gift cards?
AFAIK At least one user of the other instance has to be subscribed to the community in order for the community to be “synced” with the other instance (for lack of a better word).
