A Spousal IRA might be a good idea for you and your family.
If you file your federal income tax return as married filing jointly and meet certain other conditions, you can contribute to an IRA (traditional or Roth) for your spouse even if he or she has little or no taxable compensation of his or her own for the year of the contribution. This is usually described as making a contribution to a spousal IRA.
A spousal IRA is not, however, a special type of IRA. It is merely a way of describing the fact that you are making a contribution to your spouse's traditional or Roth IRA.
