SECURE 2.0 created a real fix for a problem that used to scare people away from 529 plans: what happens to leftover money if the beneficiary doesn’t need it all for school. Since 2024, unused 529 funds can be rolled directly into the beneficiary’s own Roth IRA, tax- and penalty-free, under a specific set of rules that are still in effect for 2026.
The $35,000 Lifetime Cap
The rollover is capped at $35,000 total per beneficiary, for their entire lifetime — not per year, not per 529 account. Once $35,000 has moved from any combination of that beneficiary’s 529 accounts into their Roth IRA, the door closes for good, regardless of how much money remains in the 529 plan.
The 15-Year Account Age Rule
The 529 account has to have been open for at least 15 years before any rollover is allowed. There’s some ambiguity the IRS hasn’t fully clarified about whether changing beneficiaries restarts that 15-year clock, so if you’re planning around this, keep the same beneficiary on the account from the start rather than testing the gray area.
The Annual Limit Still Applies ($7,500 in 2026)
A 529-to-Roth rollover doesn’t get its own separate bucket — it counts against the beneficiary’s regular annual Roth IRA contribution limit, which is $7,500 for 2026 (see our full breakdown of 2026 retirement contribution limits). That means a $35,000 rollover takes a minimum of about five years to complete even if you do nothing else, and the beneficiary needs earned income that year at least equal to the amount rolled over — a $7,500 rollover requires $7,500 of the beneficiary’s own earned income, same as a regular Roth contribution would.
Contributions From the Last 5 Years Don’t Count
Any 529 contributions (and their earnings) made within the five years before the rollover date are excluded from what’s eligible to move. In practice, this means you can’t dump a large contribution into a 529 account and roll it straight into a Roth IRA shortly after — the rollover only reaches money that’s been sitting in the account for a while.
Who Actually Benefits
This is most useful for families who saved conservatively (or a grandparent overfunded the account) and the beneficiary ended up not needing all of it — a cheaper school, a scholarship, or skipping college altogether. Rather than paying income tax plus a 10% penalty on non-qualified withdrawals, the money can become a meaningful head start on the beneficiary’s own retirement instead, working alongside strategies like the backdoor Roth IRA for beneficiaries who eventually earn too much to contribute directly.
