A 529 account is a tax-advantaged savings account for education expenses, named after the section of the tax code that created it.

Money you put into a 529 grows tax-free, and you pay no federal tax on the growth when you withdraw it to pay for college, trade school, K-12 tuition, student loan repayment, or apprenticeships. Each state runs its own 529 plan, and you can open an account in any state's plan regardless of where you live or where your child will go to school. The account is owned by you (the parent or grandparent), not the child, which means you keep control of the money and can change the beneficiary to another family member if plans change.

The main trade-off is that if you withdraw money for anything other than education, you owe income tax on the earnings plus a 10% penalty—though the money you contributed comes out tax-free. There is no annual contribution limit, but gifts over $18,000 per person per year (in 2024) trigger gift tax reporting, and some states cap total account balances at $235,000 to $550,000 depending on the plan.

Key Takeaways

  • Money in a 529 grows tax-free and withdrawals for education expenses are not taxed federally, but non-education withdrawals trigger income tax plus a 10% penalty on earnings.
  • You choose which state's plan to use, and you can change the beneficiary to another family member without penalty if the original child does not need the money.
  • Each state plan has different investment options, fees, and state tax deductions, so comparing plans before opening an account can save you money.
  • Contributions do not reduce your federal taxes, but many states offer a state income tax deduction for contributions to their own plan.

How money grows in a 529 and what you pay in taxes

When you open a 529, you choose how to invest the money—usually through mutual funds or age-based portfolios that automatically shift from stocks to bonds as the child gets older. The earnings on those investments (dividends, capital gains, interest) accumulate tax-free inside the account. When you withdraw money to pay for tuition, room and board, books, computers, or other education costs, the earnings come out tax-free at the federal level.

If you withdraw money for a non-education purpose, you owe federal income tax on the earnings portion at your ordinary tax rate, plus a 10% federal penalty on those earnings. The contributions themselves always come out tax-free, since you already paid tax on that money when you earned it. For example, if you contributed $10,000 and the account grew to $15,000, and you withdraw $15,000 for a car, you owe income tax and a 10% penalty only on the $5,000 in earnings.

Some states also tax 529 earnings at the state level, even for education withdrawals. Check your state's plan rules before opening an account, because a few states do not tax 529 earnings at all, while others do.

State tax deductions and how they vary

Many states offer an income tax deduction for contributions to their own 529 plan. If you live in New York and contribute to New York's plan, you may deduct that contribution from your state taxable income. The deduction amount varies: some states allow you to deduct up to $235,000 per beneficiary per year, while others cap it at $2,500 or $5,000 per year. A few states offer no deduction at all.

You do not get a federal income tax deduction for 529 contributions, only a state one (and only if your state offers it). If you live in one state but open a plan in another state to get better investment options or lower fees, you typically lose the state tax deduction—though a handful of states allow deductions for out-of-state plans. Before opening an account, look up your state's plan and its deduction rules on your state's tax authority website.

Investment options and fees across different plans

Each state's 529 plan offers its own set of investment choices. Some plans offer only a handful of mutual funds; others offer dozens. Many plans include age-based portfolios that automatically rebalance as the child approaches college age, moving from aggressive stock-heavy funds to conservative bond-heavy funds. You can also choose your own mix of funds in a self-directed option.

Fees vary significantly between plans. Some charge annual account maintenance fees ($25 to $50), investment management fees (0.2% to 1% of your balance per year), or both. A few plans charge no annual fee and have low investment costs. Since fees compound over time, a plan with 0.5% annual costs will grow noticeably more than one with 1.5% costs, all else equal. Use your state's plan website or a 529 comparison tool to see the fee structure before you commit.

Who can open a 529 and who can be the beneficiary

You can open a 529 account if you are a U.S. citizen or resident alien with a Social Security number or tax ID. The beneficiary can be your child, grandchild, niece, nephew, or even yourself. The account owner (you) keeps control of the money and decides when and how much to withdraw, regardless of the beneficiary's age. This is different from a custodial account, where the child gains control at age 18 or 21.

You can change the beneficiary to another family member at any time without tax or penalty. For example, if your oldest child gets a scholarship and does not need the money, you can transfer the account to your younger child, a grandchild, or even a cousin. The money stays in the account and keeps growing tax-free under the new beneficiary's name.

What counts as an education expense and what does not

may have access to education expenses include tuition and fees at any accredited college, university, trade school, or graduate school; room and board if the student is enrolled at least half-time; books and supplies; computers and internet access; and up to $35,000 in student loan repayment (lifetime limit). Starting in 2024, you can also roll up to $35,000 from a 529 into a Roth IRA in the beneficiary's name, subject to income limits and a five-year holding period on the original contributions.

Expenses that do not count include room and board for students not enrolled at least half-time, transportation, insurance, and living expenses beyond what the school includes in its cost of attendance. If you are unsure whether an expense qualifies, check the IRS Publication 970 or ask your plan administrator before withdrawing.

Changing beneficiaries and what happens if money is left over

If your child receives a scholarship, gets into a military academy, or simply does not need all the money in the 529, you have several options. You can change the beneficiary to a sibling, cousin, niece, nephew, or grandchild without any tax or penalty. You can also roll the account into an ABLE account if the beneficiary qualifies, or roll up to $35,000 into a Roth IRA in the beneficiary's name (subject to income limits and contribution rules).

If you withdraw money that is not used for education, you owe income tax and a 10% penalty on the earnings only—not on the contributions. Some plans also allow you to recapture unused contributions by rolling them into a Roth IRA, which lets you preserve some of the tax advantage even if the original education plan falls through. The rules for rollovers changed in 2024, so check your plan's current policy.

How a 529 affects financial aid and other considerations

A 529 account owned by a parent counts as a parental asset on the Free Application for Federal Student Aid (FAFSA), which can reduce the student's aid package by up to 5.64% of the account balance per year. A 529 owned by a grandparent or other relative does not count on the FAFSA at all, which is why some families use grandparent-owned accounts to preserve aid may be able to access. However, grandparent-owned accounts have different rules for rollovers and beneficiary changes, so weigh the aid benefit against the loss of flexibility.

If the beneficiary is a dependent with their own income, the 529 earnings may be taxed at the child's tax rate rather than the parent's if the child has unearned income above a certain threshold. This is rarely a problem, but it is worth knowing if the child has investment income from other sources.

Frequently Asked Questions

Can I use 529 money for trade school or apprenticeships?

Yes. Any accredited trade school, certificate program, or apprenticeship registered with the Department of Labor counts as a may have access to education institution. Room and board, books, and tools all count as may have access to expenses if they are required by the program.

What happens if I open a 529 and then the child decides not to go to college?

You can change the beneficiary to another family member without penalty. If no family member needs the money, you can withdraw it, but you will owe income tax and a 10% penalty on the earnings. Starting in 2024, you can also roll up to $35,000 into a Roth IRA in the beneficiary's name if they meet income limits.

Can I open a 529 for myself?

Yes. You can be both the account owner and the beneficiary. This works if you are going back to school, attending trade school, or pursuing a graduate degree. The same tax rules apply—earnings grow tax-free and withdrawals for education are not taxed.

Do I have to use my state's 529 plan?

No. You can open an account in any state's plan regardless of where you live. However, you may lose your state income tax deduction if you choose an out-of-state plan. Check whether your state allows deductions for out-of-state plans before deciding.

How much can I contribute to a 529 without triggering gift tax?

You can contribute up to $18,000 per person per year (in 2024) without filing a gift tax return. Married couples can give $36,000 per beneficiary per year. Amounts above that require a gift tax return, though you typically do not owe tax unless you exceed your lifetime gift tax exemption. Some plans allow a special election to spread a large contribution over five years for gift tax purposes.
