Roth IRA contributions are not taxed at the time you contribute the funds to your Roth IRA. However, your contributions come from post-tax income.You pay taxes on your income today, but not in the future.ithdrawals 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.
