Can an individual contribute to both a Roth IRA and a Traditional IRA in the same year?

Yes. An individual may make IRA contributions to both a Roth and a Traditional IRA, providing the combined contribution total does not exceed the contribution limit for the year.

For instance, for tax year 2007, an individual may make a total contribution - whether to one IRA or partially to a Traditional IRA and partially to a Roth IRA - of up to $4,000 or 100% of compensation, whichever is less. If the individual reaches age 50 by the end of 2007, the dollar (contribution) limit is $5,000 ($4,000 plus a "catch-up" contribution of $1,000).

The total amount contributed to both the Traditional and the Roth cannot exceed $4,000 ($5,000 if age 50 or older) for tax year 2007.
