Roth 的tax是这样的：your earnings and withdrawals can grow tax-fre

A Roth IRA is a retirement account that allows you to contribute after-tax dollars. While you pay taxes on the money you contribute, your earnings and withdrawals can grow tax-free. You can withdraw your contributions at any time without tax or penalty, and once you are 59½ years old and your account has been open for at least five years, you can withdraw your earnings tax-free and penalty-free
