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.
All traditional IRA and 401(k) withdrawals require that you pay taxes at ordinary income rates. Contributions to a Roth IRA can be taken out at any time, and its earnings may be withdrawn penalty and tax-free after five years.
