The Roth IRA allows you to make annual non-deductible contribution annually. However, this amount is reduced by contributions made to your traditional IRAs.
Although you cannot claim a tax deduction, you can withdraw your contributions tax- and penalty-free at any time.
After the account is open five tax years, earnings can be withdrawn tax- and penalty-free for any of these reasons: age 59 1/2, disability, death, or a first-time home purchase up to a lifetime limit of $10,000
Please check with your tax adviser when planning to invest in an IRA.
