Are 529 plan contributions tax deductible?

There is no federal tax deduction for 529 contributions, but over 30 states offer a state income tax deduction or credit for contributions to an in-state plan.

What happens to unused 529 funds?

Starting in 2024, unused 529 funds can be rolled into a Roth IRA for the beneficiary (up to $35,000 lifetime, subject to annual Roth IRA contribution limits). You can also change the beneficiary to another family member.

Can 529 plans be used for K-12 tuition?

Yes. Federal rules allow up to $10,000 per year per beneficiary for K-12 tuition. However, not all states conform to this rule for state tax purposes.

529-to-Roth IRA Rollover (New Rule)

Starting in 2024, the SECURE 2.0 Act allows unused 529 funds to be rolled into a Roth IRA for the beneficiary, subject to these rules:

The 529 account must have been open for at least 15 years
Contributions from the last 5 years (and their earnings) are not eligible
Subject to annual Roth IRA contribution limits ($7,000 in 2025, $7,500 in 2026 for under 50)
Lifetime cap of $35,000 per beneficiary

This is a significant change that reduces the risk of “overfunding” a 529.

What to Watch

Non-qualified withdrawals are taxed and penalized (10% penalty on earnings).
State rules vary; check your state benefits.
Changing the beneficiary to another family member is allowed without penalty.
