Do you have to pay taxes on a brokerage account yearly? Or only when money is taken out of the account?
Taxes are on dividends and capital gains yearly. I believe the brokerage will send all necessary tax forms.
Agreed with @Chadmethner. For non-tax-advantaged accounts, you receive a tax form from the brokerage that you use (e.g., Fidelity, Schwab, Vanguard) in Q1 generally for the previous year. It will breakdown what taxes are owed!
