What Is the Most Overlooked Tax Break for Arizona Retirees?
For Arizona retirees, the most overlooked tax break is the state income tax deduction for 529 education savings plan contributions, up to $2,000 per beneficiary for single filers and $4,000 per beneficiary for married couples filing jointly, every year, with no limit on the number of beneficiaries. Two things make it easy to miss. First, it applies to contributions made to any state's 529 plan, not just Arizona's own AZ529 plan, so households who assume they'd need to switch plans to get the deduction often just skip it. Second, and more commonly missed by grandparents specifically, the deduction belongs to whoever makes the contribution, not whoever owns the account. A grandparent who contributes directly to a grandchild's 529, even one the parents opened and own, can claim the Arizona deduction on their own return for the year they contributed, something most grandparents making education gifts have no idea they're entitled to.
