A Roth IRA is a type of individual retirement account that allows individuals to save for retirement with tax-free growth. Contributions to a Roth IRA are made with after-tax dollars, meaning you pay taxes on the money before you deposit it into the account. This allows for tax-free withdrawals in retirement, provided certain conditions are met. One of the key benefits of a Roth IRA is that there are no required minimum distributions (RMDs) during the account holder's lifetime. This feature allows your investments to grow tax-free for a longer period, making it an attractive option for long-term retirement savings.
