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 your investments to grow tax-free, and qualified withdrawals in retirement are also tax-free. To be eligible for a Roth IRA, individuals must meet certain income limits. The account can hold various investments, including stocks, bonds, and mutual funds. Additionally, contributions can be withdrawn at any time without penalty, making it a flexible option for retirement savings.
