529 Plan Withdrawal Penalty: What It Costs

The 529 plan withdrawal penalty on a $64,608 account cashed out for something other than school is $3,221, and the full federal bill is $7,086 at a 12% rate: $3,865 of income tax plus that penalty, because both land only on the $32,208 of earnings, never on the $32,400 you put in. That is $150 a month from birth to 18 at 7%. The 12% assumes all the earnings fit inside your 12% bracket. At a 22% rate the bill is $10,307, and paid out to a kid with no other income it is $4,906, if the kiddie tax does not apply.

Key takeaways

The 529 plan withdrawal penalty is a 10% additional tax on the earnings part only. On our 18-year account that is $3,221, or 5% of the $64,608 balance (IRS Publication 970).
The earnings are also taxed as income. At 12% the total bill is $7,086 and the family keeps $57,522. At 22% it keeps $54,301.
Whoever receives the check owes the tax. Paid to a kid with no other income, 2026 brackets put the bill at $4,906, if the kiddie tax does not reach him (IRS Pub 970, Topic 553).
A tax-free scholarship waives the 10% up to the scholarship amount. Income tax on the earnings still applies, so a full cash-out under that exception nets $60,743 at 12%.
A 529 open 15 years can roll up to $35,000 per kid for life into the kid's Roth IRA, capped each year at the smaller of the IRA limit ($7,500 in 2026) or the kid's pay (26 U.S.C. 529).
California adds 2.5% on the earnings ($805 here) on top of its regular income tax on them. New York takes back every deduction it gave on its own 529 plan, on top of taxing the earnings.

We spent an evening inside IRS Publication 970 for this, which is a sentence neither of us thought we would type as dads.

Here is the short version. The penalty is smaller than the internet makes it sound, the income tax is bigger than people expect, and the exceptions do more work than either.

What is the 529 plan withdrawal penalty?

It is a 10% additional tax. IRS Publication 970 says that if you receive a taxable distribution, "you must also pay a 10% additional tax on the amount included in income."

The key words are "included in income." A 529 withdrawal is split in 2. The part you contributed comes back as "a return of the investment in the plan," with no tax. Only the earnings part is included in income.

So the 10% never touches your own money. It hits the growth, and so does regular income tax.

The statute behind it is 26 U.S.C. 529(c)(6). It borrows the Coverdell ESA penalty and applies it "in the same manner" to 529 money. Your plan reports the split each year on Form 1099-Q: gross distribution in box 1, earnings in box 2, basis in box 3.

Every withdrawal carries its share of the earnings, and the 1099-Q shows the split. You cannot pull the contributions out first and leave the earnings behind, which is a trick a Roth IRA can do and a 529 cannot.

How is a 529 plan taxed if not used for education, in dollars?

We ran the house baseline: $150 a month from birth to 18, deposited at the end of each month, 216 deposits, 7% a year compounded monthly, no fees.

That grows to $64,608. You put in $32,400. The other $32,208 is earnings, which is 49.9% of the balance.

Now pull every dollar out for something that is not school. A car, a down payment, a gap year in Lisbon. Here is what each exit leaves the family.

$64,608 balance at 18 ($32,400 contributed, $32,208 earnings), full withdrawal at once, federal tax only unless noted. Dadvesting calculation, run Oct 2, 2026. Rules: IRS Publication 970, IRS 2026 inflation adjustments, FTB 3805P instructions.
How the money comes out	Income tax	10% penalty	Family keeps
Spent on qualified education	$0	$0	$64,608
Not for school, kid's own return, no other income, 2026 brackets	$1,685	$3,221	$59,702
Not for school, 12% rate	$3,865	$3,221	$57,522
Not for school, 12% rate, CA 2.5% additional tax only	$3,865 + $805 CA	$3,221	$56,717
Not for school, 22% rate	$7,086	$3,221	$54,301
Tax-free scholarship covers it, 12% rate	$3,865	$0	$60,743

Read the penalty column again. It is $3,221 on every non-school line, because it is a flat 10% of the same $32,208.

The column that moves is income tax. At 12% it is $3,865. At 22% it is $7,086. On the kid's own return it is $1,685, because the first $16,100 of his income in 2026 is covered by the standard deduction, the next $12,400 is taxed at 10%, and the last $3,708 is taxed at 12%.

The 12% line assumes all $32,208 fits inside your 12% bracket. For a married couple that bracket ends at $100,800 of taxable income in 2026, so a family already above about $68,600 taxable pays 22% on part of it.

The California line counts only the state's 2.5% additional tax. California also taxes the $32,208 as regular state income, so a California family pays its own state rate on top of the $805.

The same $64,608 and the same penalty across all 6 lines are no accident. We held the balance still on purpose so the only thing changing is the tax.

The 12% and 22% lines match our Trump Account vs 529 numbers, which run the same $150 a month for the same 216 months.

What the math says

The 529 plan withdrawal penalty on an 18-year, $150-a-month account is $3,221, or 5% of the balance. The full non-school bill at a 12% federal rate is $7,086, so the family keeps $57,522 of $64,608, about 89%. The variable that moves the answer is the tax rate of whoever receives the money: $4,906 on the kid's own return with no other income and no kiddie tax, $10,307 at 22%.

Who pays the tax on a 529 withdrawal, you or the kid?

Whoever the IRS treats as the recipient. Publication 970 says the beneficiary is the recipient only if the money goes "directly to the designated beneficiary" or to a school for the beneficiary. "Otherwise, the account owner is considered the recipient."

That 1 sentence is worth $5,401 on our numbers. A parent at 22% pays $10,307. A kid with no other income pays $4,906. The penalty is the same $3,221 either way. The gap is all income tax.

There is a catch, and it has a name nobody enjoys saying out loud: the kiddie tax.

IRS Topic 553 says a child's unearned income over $2,700 can be taxed using the parents' rate if the child was under 18 at year end, 18 with earned income no more than half of his own support, or a full-time student from 19 to 23 with the same support test.

529 earnings are unearned income. So the $4,906 line holds for a kid who falls outside those rules in the year of the withdrawal, like a 19-year-old who is not a full-time student, or any kid 24 or older. Inside them, the kid's line drifts back toward the parents' rate.

The $4,906 also assumes no other income. Wages use up the standard deduction first and push the bill toward the 12% line.

Does the 529 scholarship exception wipe out the penalty?

It wipes out the 10%. It does not wipe out the income tax.

Publication 970 waives the additional tax on money included in income "because the designated beneficiary received" a tax-free scholarship or fellowship. The exception "applies only to the extent the distribution isn't more than the scholarship."

So a kid who lands $20,000 in tax-free scholarships lets the family pull up to $20,000 with no penalty. The earnings inside that $20,000 are still taxed as income.

On our table, if scholarships covered the full $64,608, the family keeps $60,743 at 12%. That is the $3,221 penalty back, and nothing more.

The same 10% waiver covers a short list of other cases in Publication 970.

Exceptions to the 10% additional tax on taxable 529 distributions. Source: IRS Publication 970 (2025), checked Oct 2, 2026.
Exception	10% waived?	Income tax on earnings?
Tax-free scholarship or fellowship, up to its amount	Yes	Yes, still owed
Veterans' educational assistance, up to its amount	Yes	Yes, still owed
Employer-provided educational assistance, up to its amount	Yes	Yes, still owed
Attendance at a U.S. military academy, up to the cost of advanced education	Yes	Yes, still owed
Beneficiary dies	Yes	Yes, still owed
Beneficiary becomes disabled, as a physician determines	Yes	Yes, still owed
Expenses used for the American opportunity or lifetime learning credit	Yes	Yes, still owed

Every exception on that list saves the same 10%. None of them is a free exit.

What if my kid doesn't go to college at all?

Then "college" may be the wrong word for what the 529 covers. Publication 970 counts any accredited "college, university, vocational school, or other postsecondary educational institution" that can take federal student aid. Trade school counts if the school qualifies.

It also counts fees, books, supplies and equipment for an apprenticeship registered with the Secretary of Labor. And since July 4, 2025, the statute adds qualified postsecondary credentialing expenses under 529(f).

There is no clock on any of it. Publication 970 forces a Coverdell ESA to pay out within 30 days after the beneficiary turns 30. Its 529 chapter has no matching deadline, so a kid who skips college at 18 and goes at 26 can still use the money.

And there are 3 tax-free exits that do not involve this kid going to school at all. Those are the next 3 sections.

Can I change the 529 beneficiary without paying tax?

Yes, inside the family. Publication 970 says "There are no income tax consequences" when the beneficiary is changed to a member of the beneficiary's family.

The family list is wider than most people expect. It covers the kid's siblings and step-siblings, his own future kids, nieces and nephews, aunts and uncles, in-laws, the spouses of all of those, first cousins, his own spouse, and his parents and grandparents.

That last 1 matters. A parent is on the list, so a dad can name himself and use the money for his own degree or certificate. The second kid is on the list too, which is the cleanest exit for a family with 2.

The account moves over with its earnings intact. No income tax and no 10% on the change.

529 to Roth IRA rollover: what are the rules for leftover money?

SECURE 2.0 opened this door for distributions after Dec 31, 2023. IRS Publication 590-A lists the conditions, and 26 U.S.C. 529(c)(3)(E) has the statute text.

15-year account rule. The 529 must have been maintained for the 15-year period ending on the day of the rollover. A 529 opened at birth clears it at 15. Publication 590-A does not say whether a beneficiary change restarts the 15-year clock.
The 5-year lookback. Contributions made in the last 5 years, and the earnings on them, cannot roll. On our account at 18 that is the last $9,000 of deposits, now worth $10,739, which leaves $53,869 eligible.
$35,000 lifetime. The total across all years stops at $35,000 per beneficiary.
Annual IRA limit. Each year's rollover is capped at the beneficiary's Roth IRA limit, minus anything else he put into any IRA that year. The 2026 IRA limit is $7,500.
The kid needs earned income. The annual cap is the 408A(c)(2) amount, which runs through section 219, and that is the smaller of the dollar limit or taxable compensation. IRS Publication 590-A gives the example of a student who earned $3,500 and could contribute only $3,500.
Direct transfer only. The money goes trustee to trustee into a Roth IRA in the beneficiary's name.
No income limit. Section 408A(c)(3)(E) adds the rollover back on top of any Roth income phase-out, so a high-earning kid can still take it.

Run it on our numbers. The $35,000 cap covers 54.2% of the $64,608 balance. At today's $7,500 limit it takes 5 years to move: $7,500 a year for 4 years, then $5,000.

That only works if the kid earns at least that much each of those years. A kid who earns $4,000 a year moves $4,000 a year.

We priced where that $35,000 can go by 65 in our custodial Roth IRA vs 529 breakdown. California does not follow the federal rule here. The FTB says these rollovers are "includible in California taxable income and subject to an additional tax of 2½%."

Does my state take back the 529 tax deduction?

Some do, and it is the line most cash-out math forgets.

New York is the clearest case we found in a primary source, for money in New York's own 529 plan. The 2025 IT-201 instructions say a withdrawal "is considered nonqualified unless it is used" for listed purposes like higher education, qualified student loans or a 529 to Roth rollover. A nonqualified withdrawal triggers an addition to New York income on the Line 22 worksheet. The worksheet adds back the deductions you took on contributions.

New York lets you deduct up to $5,000 a year, or $10,000 joint, so all $1,800 a year of our $150 a month would have been deducted. Pull it all out for a car and New York claws back the full $32,400 of deductions and taxes the $32,208 of earnings too. On the Line 22 worksheet the 2 together come to the whole $64,608 withdrawal.

Here is the size of that at a 5% example state rate, which is our round number, not New York's actual rate.

State tax on the $32,208 of earnings: $1,610.
Recapture of $32,400 in deductions: $1,620.
Federal 12% plus penalty, from the table: $7,086.
Family keeps $54,292, which is $3,230 less than the federal-only $57,522.

The recapture is the same $1,620 the deductions saved going in. The state lent you the break and wants it back. New York also counts a move to another state's 529 as nonqualified, which matters if you are weighing a switch to a cheaper plan in another state.

California works the other way. It gives no deduction at all, then adds its 2.5% on the earnings, which is the $805 in the table.

What counts as 529 plan qualified expenses?

For college and other postsecondary schools, Publication 970 lists these:

Tuition and fees, plus books, supplies and equipment the school requires.
Room and board for a student enrolled at least half-time, up to the school's cost-of-attendance allowance or the actual charge for campus housing, whichever is greater.
A computer, software and internet used mainly by the student while enrolled.
Fees, books, supplies and equipment for a registered apprenticeship.
Up to $10,000 of student loan principal and interest per person, for life, for the beneficiary or a sibling.

K-12 is in there too. The statute raised the yearly K-12 cap from $10,000 to $20,000 per beneficiary for tax years starting after Dec 31, 2025.

Your state may not agree. New York treats K-12 tuition withdrawals as nonqualified and claws back the deduction, and California does not follow the 2025 federal expansion.

Anything outside those lines is a nonqualified withdrawal, and the table above prices it. If the kid's FAFSA is part of your picture, we ran how a 529 counts in our FAFSA article.

How much does the rate of return change the penalty?

A lot, because the penalty is a share of earnings and earnings are the part that compounds. We ran the same $150 a month for 216 months at 3 rates.

$150 a month, 216 end-of-month deposits ($32,400), full non-school withdrawal at 18, federal tax only. Dadvesting calculation, run Oct 2, 2026.
Return	Balance at 18	Earnings	10% penalty	Total cost at 12%	Total cost at 22%
5%	$52,380	$19,980	$1,998	$4,396	$6,394
7%	$64,608	$32,208	$3,221	$7,086	$10,307
9%	$80,453	$48,053	$4,805	$10,571	$15,377

At 12%, the full non-school bill runs 8.4% of the balance at 5%, 11.0% at 7% and 13.1% at 9%. The better the account does, the more of it is earnings, and the more a non-school exit costs.

The verdict does not flip at any of the 3 rates. The family still keeps most of the money every time.

How we ran the numbers

1 account, run end to end with a Python script. Every figure on this page is what the script printed.

$150 a month, deposited at the end of each month, 216 months (birth to 18), $32,400 contributed.
7% nominal annual return, compounded monthly. Sensitivity at 5% and 9%.
No plan fees, no inflation adjustment.
Full balance withdrawn at once at the end of month 216, all of it for a non-qualified purpose unless the line says otherwise.
Income tax on the earnings only, at a flat 12% or 22%, assuming the earnings do not cross a bracket. The kid line uses 2026 single brackets and the $16,100 standard deduction with no other income, and assumes the kiddie tax does not apply.
10% additional tax on the earnings only. The scholarship line assumes tax-free scholarships at least equal to the withdrawal.
The California line counts only the 2.5% additional tax on earnings, not California's regular income tax on them. The recapture example uses a 5% example state rate, not any real state's rate, with every contribution deducted. State income tax is not modeled in the other lines.
Every figure rounded to the dollar. Every difference is 1 rounded figure minus another.

Frequently asked questions

What is the penalty for withdrawing from a 529 plan for non-education expenses?

A 10% additional tax on the earnings part of the withdrawal, plus regular income tax on those same earnings. Contributions come back with neither. On $150 a month for 18 years at 7%, that is $3,221 of penalty and $7,086 total at a 12% rate.

What happens to 529 leftover money after college?

It can stay invested with no federal deadline, move to a family member as the new beneficiary with no income tax, roll up to $35,000 into the kid's Roth IRA after 15 years, or come out as a taxed, penalized withdrawal.

Can I withdraw 529 money if my kid gets a scholarship?

Yes. The 10% is waived up to the amount of the tax-free scholarship, per IRS Publication 970. Income tax on the earnings part still applies.

Can unused 529 funds go to a Roth IRA?

Yes, if the 529 has been open 15 years. Up to $35,000 per beneficiary for life, capped each year at the smaller of the IRA limit ($7,500 in 2026) or the kid's taxable compensation, by direct transfer into the kid's own Roth IRA. Money added in the last 5 years, and its earnings, cannot roll.

Who pays tax on a non-qualified 529 withdrawal?

The recipient. IRS Publication 970 treats the beneficiary as the recipient only when the money goes straight to him or to his school. Otherwise the account owner owes the tax.

Is there an early withdrawal penalty on a 529 plan?

Not an age-based one. A 529 has no age 59 and a half rule like an IRA. The same 10% additional tax applies to the earnings of any nonqualified withdrawal, whether the kid is 5 or 25.

What are the 529 plan withdrawal rules to avoid the penalty?

Match each tax year's withdrawals to that same year's adjusted qualified education expenses. IRS Publication 970 compares all 529 distributions for the tax year to qualified expenses minus tax-free aid like scholarships, and expenses used for the American opportunity or lifetime learning credit cannot count twice. Form 1099-Q reports the withdrawal, not the expenses, so the receipts are what show the match.

Is there a time limit to use 529 money?

No federal one. IRS Publication 970 forces a Coverdell ESA to pay out after the beneficiary turns 30, and its 529 chapter has no matching rule. Individual plans can set their own terms in their disclosure documents.

Rules current as of Oct 2026: 10% additional tax on 529 earnings, 2026 IRA limit $7,500, 529 to Roth lifetime cap $35,000 after 15 years, 2026 single standard deduction $16,100, California additional tax 2.5%, K-12 cap $20,000 from 2026. Rates and limits move, so check the date on this line before you lean on it.
