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.

In a nutshell, Roth IRA contributions are made with after-tax money, while contributions to a traditional IRA may qualify for a tax deduction for the year the contribution was made. Contributions to an IRA for the 2016 tax year must be made by the tax-filing deadline in April. With the Roth, taxes are paid on the front end so that in retirement, all distributions -- including interest and earnings -- are tax-free. Conversely, the traditional IRA generally gets a tax advantage at the time the contribution is made, but distributions are taxed as ordinary income in retirement.
