In the case of married taxpayers, each spouse is entitled to a reduction not in excess of $3,000 for the spouses’ contributions to the accounts.

The deduction applies only to contributions where the taxpayer is the designated beneficiary of the account, or a spouse, parent, grandparent, sibling or child of the designated beneficiary, related by blood, marriage, or legal adoption.
