Over the years, the Castle has been home to the Smithsonian Institution Archives and the Woodrow Wilson International Center for Scholars. Today, the Castle houses the Institution's administrative offices and the Smithsonian Information Center.
Withdrawals made after age 59 and 1/2 are normal retirement withdrawals and are not taxed. You paid tax on that income when you first contributed to the Roth IRA. If the withdrawal is made before age 59 and 1/2 and is only up to the amount that has been contributed to the Roth IRA then no income tax is charged. Withdrawals of contributions are tax-free.
For example, if you convert $15,000 to your Roth IRA from your traditional IRA and you take out that $15,000 before five years pass, you'll owe $1,500 in early-withdrawal penalties, but no additional income tax. This penalty is waived if you're at least 59 1/2 when you take the distribution.
