I have leftover 529 money. Now what?

Answer a few questions and we will show you the ways you may be able to reuse, transfer, preserve or withdraw what is left. Having money left in a 529 does not mean the money is wasted — most of the paths cost nothing in federal tax.

Your pathways, ranked for your situation

Money left in a 529 is not money wasted.

Most of what can be done with a leftover balance costs nothing in federal tax. Cashing out is only one of the paths, and on the numbers it is usually the most expensive. Answer a few questions and we will show you which pathways are open, which need a condition checked first, and what each one would actually cost.

  • What is open to you

    Reuse, transfer, rollover and withdrawal, ordered by your goal.

  • What each one costs

    Federal income tax and the additional tax, worked out separately.

  • What we cannot answer

Leftover 529 money is more workable than it looks

The common assumption is that money left in a 529 is trapped, and that getting it out means tax and a penalty. That is true of exactly one of the available routes. Most of the others cost nothing in federal tax.

A surplus can stay invested for a future student, move to another qualifying family member, fund graduate school or a qualifying apprenticeship, or — within limits set in IRS Publication 590-A — move into the beneficiary’s Roth IRA. Cashing out is the last resort rather than the default.

The Roth rollover, and its real constraints

The 529-to-Roth rollover is the route people ask about most, and it carries more conditions than the headline suggests. The account must have been open at least 15 years. There is a lifetime cap of $35,000 per beneficiary. Each year’s rollover counts against that year’s IRA contribution limit — $7,500 for 2026 — so the full amount cannot move at once. Contributions made in the last 5 years are excluded, and the transfer must go trustee to trustee.

Taken together those conditions mean the rollover is a multi-year process rather than a single transaction, and that it suits a modest surplus far better than a large one.

Where state rules diverge from federal ones

Federal treatment is the same everywhere. State treatment is not, and it splits into two separate questions that are easy to conflate: whether your state taxes the earnings in a distribution, and whether it claws back a deduction or credit you previously claimed. A state can do one and not the other.

Those are held apart in this tool deliberately, and where a state’s treatment could not be confirmed against a source, it says so rather than guessing. A total that reads “at least” some amount is one where a known component has been counted and an unverified one has been named rather than silently set to zero.

Common questions

What happens to leftover money in a 529 plan?

It stays invested until you do something with it — there is no deadline and no forfeiture. The available routes are keeping it for a future student, changing the beneficiary to a qualifying family member, spending it on other qualified education including graduate school and some apprenticeships, rolling a limited amount to a Roth IRA, or withdrawing it and paying tax on the earnings plus the 10% additional federal tax.

Can I roll a 529 into a Roth IRA?

Within limits, yes. Per Publication 590-A, the account must be at least 15 years old, the lifetime cap is $35,000 per beneficiary, each year counts against that year’s IRA contribution limit, contributions from the last 5 years are excluded, and the transfer must be made directly between trustees.

Can I change the beneficiary to myself?

The rules turn on whether the new beneficiary is a qualifying member of the current beneficiary’s family, and that definition in Publication 970 is broad — it includes parents, siblings, children, in-laws and first cousins among others. Whether a particular change qualifies depends on the relationship, and your plan administrator can confirm the mechanics.

Is there a penalty for withdrawing 529 money for something else?

The earnings portion is subject to income tax plus an additional federal tax of 10%. Your original contributions come back untaxed. Several exceptions remove the additional tax — among them death or disability of the beneficiary, a tax-free scholarship, and attendance at a U.S. military academy — each described in Publication 970, and some limited to the amount involved.

Does my state tax a 529 withdrawal?

It depends on the state, and on which event you are asking about — a cash-out, a rollover, a scholarship withdrawal and a beneficiary change can be treated differently within the same state. The tool holds state income tax and recapture of a previously claimed benefit apart, and reports which of the two it can verify for your state.
