Secure 2.0 Section 126 allowed for 529 college savings plan balances to be rolled over tax free into a Roth IRA in the name of the 529 beneficiary, starting with tax year 2024. The IRS released its final implementation guidance in February 2026, clearing up most of the administrative uncertainty that had slowed adoption in 2024 and 2025. The rule is now fully operational for the 2026 tax year. Understanding the details matters because the rule is genuinely useful for a specific set of families but is much more limited than the early coverage made it sound.
Here are the exact rules as of 2026. The 529 account must have been open for at least 15 years before any rollover is made. Contributions made within the last 5 years are not eligible for rollover. The annual rollover is capped at the standard Roth IRA contribution limit, which is 7,000 dollars in 2026, or 8,000 for individuals age 50 and older. The lifetime cap on 529 to Roth rollovers is 35,000 dollars per beneficiary. The rollover must go to a Roth IRA owned by the 529 beneficiary, not the account owner. The beneficiary must have earned income at least equal to the rollover amount in the year the rollover is made.
For a family that opened a 529 for a child at birth and over funded it, the new rule provides a real escape valve. Before Secure 2.0, unused 529 balances could only be pulled out for non qualified expenses, which triggered income tax and a 10 percent penalty on the earnings portion. Families could change the beneficiary to another family member, which helped but did not solve the problem if all the kids were done with school. The new rule allows up to 35,000 dollars of that stranded balance to move into a Roth IRA for the beneficiary over multiple years, which is a legitimate win.
The 15 year rule is the first gotcha. If you open a 529 for a child at age 5, you cannot roll over any of it until the child is 20. If you open it at age 12, you cannot roll over until the beneficiary is 27. The IRS has clarified that the 15 year clock restarts if you change the beneficiary on a 529. This is a change from the original ambiguity in the 2023 statute. Families who had been planning to change the beneficiary to a younger child and use the 15 year clock from the original open date will need to rethink that strategy.
The earned income requirement is the second gotcha. The beneficiary must have earned income from employment or self employment in the rollover year at least equal to the rollover amount. A teenager with a summer job can qualify for a partial rollover. A college senior who worked an internship can qualify. A young adult who is back in school full time with no job cannot receive a rollover. This requirement is the same as the standard Roth IRA contribution requirement and it catches a lot of families off guard.
The contribution limit interaction is the third detail worth understanding. The annual 529 to Roth rollover counts against the beneficiary's total Roth IRA contribution limit for the year. A 22 year old who earns 45,000 and normally would contribute 7,000 to a Roth on their own cannot also receive a 7,000 rollover. They could receive up to 7,000 combined. If the beneficiary wants the full Roth limit from their own contributions, the rollover amount has to be zero that year.
For families in the 22 percent or 24 percent federal tax bracket who over funded a 529, the math on using the rollover works cleanly. Moving 35,000 dollars over five years into a Roth IRA at the beneficiary's standard of living means that amount grows tax free for 40 to 45 years. Assuming a 7 percent annual return after inflation, 35,000 at age 22 becomes roughly 525,000 at age 62. That is a meaningful retirement boost for a young adult just starting their career.
For families who did not over fund, the rollover rule is mostly irrelevant. Most 529 accounts are under 35,000 when the beneficiary reaches college age and are used entirely for tuition, room, board, and books. The rollover is a long term planning tool for families with significant excess balances, not a general estate planning tool.
Several state 529 programs have specific quirks worth knowing. Tennessee's TNStars program allows rollovers subject to the federal rules with no additional state level restrictions. Kentucky's KY Saves 529 has clarified that state income tax deductions taken on original 529 contributions do not have to be recaptured if the funds are later rolled to a Roth. Georgia's Path2College has a similar no recapture policy. North Carolina's NC529 requires a supplemental form to be filed with the state if the rollover exceeds 10,000 dollars in a single year.
The implementation detail most commonly missed is the 5 year recency rule. Any 529 contribution made in the last 5 years is not eligible for rollover. If a parent made a 10,000 contribution to a 529 in 2024 and tried to roll over any of that amount in 2026, only the portion contributed in 2020 or earlier would qualify. For families planning rollovers in 2026, the eligible balance needs to be calculated based on contributions made through the end of 2020.
For parents thinking through long term 529 strategy, the new rule suggests a specific approach. Open 529 accounts early, preferably when the child is young. Fund aggressively in the first 10 years. Taper contributions after year 10 to preserve the 5 year recency window. Be reasonable about how much exceeds likely college costs. The rollover gives you a 35,000 escape valve per beneficiary but no more than that.
