Question: Can I still have a traditional IRA if I contribute to my 401(k) plan at work?
 
Answer :

Yes. Anyone with earned income who is under age 70½ can open and contribute to a traditional IRA. The contribution limit is $5,000 for 2009 and 2010, plus an additional "catch-up" contribution of $1,000 in 2009 and 2010 if you're 50 or older. However, you may not be able to deduct your IRA contributions if you're covered by a 401(k) plan at work. Whether or not you can deduct your IRA contributions depends on your filing status and annual income (adjusted gross income, or AGI). Specifically, for tax year 2010:

You may also qualify for a partial tax credit for amounts contributed to your traditional IRA or your 401(k) plan.
