Unlike traditional individual retirement accounts, Roth IRAs do not accept tax-deductible contributions. But withdrawals from a Roth IRA are tax-deductible, making a Roth a good investment if you expect a higher tax liability in the future. Roth IRAs also let you make penalty-free withdrawals of contributions at any time, unlike traditional IRAs. The amount of money in your Roth IRA depends on how much you've contributed and how long until you withdraw from it.
