What's the tax implication when I withdraw from my 401K at retirement?
For example, assuming a foreign stock paid $100 dividend and the foreign government withheld $10 tax. If this stock is owned in my regular investment account, I will pay US tax on $100 then get credit for $10 foreign tax paid. But what will happen if this foreign stock is held in 401K? Will the 401K brokerage be required track all such details? (If so, I would image the information is very messy and almost impossible to verify when you retire)
