If I qualify to contribute to both a Traditional IRA and a Roth IRA, what tax implications should I consider?

Having a mix of both pretax and Roth contributions can help create additional flexibility in retirement to respond to a great unknown—future tax rates. For people who expect income in retirement to be as high or higher than their current level, others who expect their tax rate in retirement to be higher than today, or younger people who expect steady income growth over their careers, Roth IRA contributions may be the better choice. But if you believe that your tax rates will be lower in retirement than they are now, you may want to prioritize pretax vehicles like the Traditional IRA.
