I agree with @Anonymous. However, you also may be limited by income and if you participate in a retirement plan at work.
You can contribute to a traditional or Roth IRA even if you participate in another retirement plan through your employer or business. However, you may not be able to deduct all of your traditional IRA contributions if you or your spouse participates in another retirement plan at work. Roth IRA contributions might be limited if your income exceeds a certain level.
