Yes, you can open and fund a Traditional or a Roth IRA even if you already contribute to an employer-sponsored retirement plan; this will help you save more than you could in your employer-sponsored plan alone. You may want to discuss this option with your tax advisor, however, please be aware that participation in an employer sponsored plan may impact deductibility in a Traditional IRA.
