Your Leftover 529 Can Move Into a Roth. The 15-Year Clock Starts When You Open It, and Your State Can Still Bill You.

If your kid skips college, wins a full ride or graduates with money still in the 529, up to $35,000 of it can move into their Roth IRA with no federal tax and no penalty.

Here’s the catch. The account has to be more than 15 years old first, and that clock started the day you opened it. No account, no clock.

So the most valuable move here costs almost nothing. Open the account.

What the rule actually says

The SECURE 2.0 Act of 2022 built this escape hatch, and it’s been live since January 1, 2024. IRS Publication 590-A lays out the strings. The money has to go straight from the 529 to a Roth IRA in the beneficiary’s name, trustee to trustee. Each year’s rollover can’t top the Roth contribution limit, which is $7,500 for 2026. The lifetime cap is $35,000. The 529 has to have been open more than 15 years. And only money that’s sat in the account more than five years can move.

Two more strings. The beneficiary needs earned income at least equal to the rollover, so a kid with a $4,000 summer job can move $4,000, not $7,500 (Saving For College). And the usual Roth income limits are waived, per California’s ScholarShare plan, which matters if your kid lands a big salary right out of school.

Translation: $35,000 takes at least five years of rollovers at today’s limit. It’s a slow drain, not a lump sum.

Where your state comes back for a cut

Federal tax-free doesn’t mean state tax-free. Each state decides, and at least two have put it in writing.

California treats the rollover as a non-qualified withdrawal. The earnings portion gets state income tax plus California’s extra 2.5% tax, according to ScholarShare. On $3,750 of earnings, the 2.5% alone is about $94, before the regular income tax.

Indiana is blunter. The Department of Revenue’s January 2026 bulletin says a Roth rollover “does not constitute a qualified education expense” for its 529 credit. That credit is worth 20% of what you put in, up to $1,500 a year. Roll money out to a Roth and you repay the lesser of 20% of the rollover or the credits you claimed. Move $7,500 and up to $1,500 goes back to Indianapolis. Move the full $35,000 and it’s up to $7,000.

In those states the Roth move can still win, because the money compounds untaxed for decades. Leave $35,000 in a Roth for 40 years at a 6% average return and it grows to about $360,000, none of it taxed on the way out under today’s Roth rules. But run the state number before you move a dollar.

The move

If you have a kid and no 529, open one this week, even with a small deposit. The 15-year clock is the one piece you can’t buy later. Our education hub covers how a 529 fits with the rest of your college plan.

If you already have an account, don’t swap the beneficiary on a whim. Saving For College says a beneficiary change will “likely” restart the clock, and the IRS hasn’t said otherwise. Save the statement that shows the opening date. ScholarShare puts the job on you, in its words: “You are responsible for determining the eligibility” of a rollover, “including tracking and documenting the length of time the 529 plan account has been open.”

Before any rollover, call your state’s plan and ask one question: does the state treat a Roth rollover as a qualified withdrawal? If the answer is no, get the repayment figure in writing. Then plug the Roth balance into our retirement calculator and decide with both numbers on the table.
