Yes, you may make contributions to both a Traditional IRA and a Roth IRA in the same year, provided the combined total contribution does not exceed your contribution limit, or 100% of earned income, whichever is less, for the year, including any catch-up contributions. For example, in 2017, the total amount you can contribute to both a Traditional IRA and a Roth IRA combined cannot exceed $5,500 ($6,500 if age 50 or older).
