A 529 plan is a savings account where money grows tax-free as long as you use it for education costs

You open an account, deposit money into it, choose investments (usually mutual funds), and that money grows over time. When your child or grandchild is ready for college or another school, you withdraw the money tax-free to pay tuition, room and board, books, or other education expenses. The key difference from a regular savings account is that the earnings — the money your investments make — are never taxed by the federal government, and usually not taxed by your state either, as long as the money goes toward school.

You can open a 529 plan in any state, regardless of where you live or where your child will go to school. The account stays in your name, not your child's, which means you control the money and decide when and how much to withdraw. If your child gets a scholarship or decides not to go to college, you have options for what to do with the unused balance.

Key Takeaways

  • Money you deposit into a 529 grows without federal income tax, and you pay no tax on the earnings when you withdraw for school expenses.
  • You choose how to invest the money — usually from a menu of mutual funds — and the investment risk and potential growth depend on which option you pick.
  • You can deposit up to $18,000 per year per person without triggering gift tax, though some states allow you to front-load five years of gifts at once.
  • Withdrawals for non-education expenses are taxed on the earnings portion, plus a 10 percent penalty, so the account works best when you are fairly confident the money will be used for school.
  • If your child does not use all the money, you can now transfer unused balances to another family member's 529 plan or roll it into a Roth IRA under certain conditions.

How you deposit money and choose investments

You start by opening an account with a plan administrator — usually a state's higher education savings program or an investment company. You provide basic information about yourself and name a beneficiary (the student who will use the money). Then you decide how much to deposit and how often. Some people make one large deposit; others contribute monthly.

Once the money is in the account, you choose from a list of investment options. Most 529 plans offer mutual funds that invest in stocks, bonds, or a mix of both. Many plans also offer "age-based" portfolios that automatically shift from stocks to bonds as your child gets closer to college age — more aggressive when there is time to recover from market drops, more conservative as you near the withdrawal years. You can change your investment choice twice per calendar year, or whenever you change the beneficiary.

The money you contribute is not tax-deductible at the federal level, but many states offer a state income tax deduction if you use your own state's plan. The amount varies by state — some states deduct the full amount you contribute, others cap the deduction, and a few offer none. Check your state's plan to see whether a deduction applies to you.

How earnings grow and stay tax-free

The real benefit of a 529 is that your money compounds without being taxed. If you invest $10,000 and it grows to $15,000 over ten years, that $5,000 in earnings is never taxed by the federal government. In a regular taxable investment account, you would owe income tax on those earnings every year, which slows growth. In a 529, the full amount keeps working for you.

This tax-free growth applies only to the earnings, not to the money you deposit. Your contributions are made with after-tax dollars, so you have already paid tax on them. But once the money is in the 529, any interest, dividends, or investment gains are sheltered from federal tax and usually from state tax as well.

Withdrawals for school and what counts as an education expense

When your child is in school, you request a withdrawal from the 529 plan. The money goes to you or directly to the school, depending on how you set it up. You can withdraw for tuition and fees, room and board (if your child is at least a half-time student), books and supplies, computers and equipment, and up to $35,000 per year for student loan repayment or K-12 tuition at a private school.

The $35,000 limit for K-12 tuition and student loan repayment is a lifetime cap per beneficiary, not an annual amount you can repeat. If you use $10,000 for K-12 tuition in one year, you have $25,000 left for those purposes over the rest of your child's life. This rule changed in 2024, so older plans may have different limits — check your plan's current rules.

You do not have to prove to the plan that you spent money on school; you straightforward request a withdrawal and receive it. However, if you withdraw more than the actual education expenses you paid, the excess earnings portion is taxed and penalized. Keep receipts and records of what you spent so you know how much you can safely withdraw.

What happens if money is left over or not used for school

If your child receives a scholarship, attends a military academy, or decides not to go to college, you have several options. You can transfer the unused balance to another family member's 529 plan — a sibling, cousin, grandchild, or even yourself if you want to go back to school. There is no tax or penalty on the transfer itself.

Starting in 2024, you can also roll up to $35,000 of unused 529 money into the beneficiary's Roth IRA, subject to certain rules: the 529 account must have been open for at least 15 years, the Roth contribution must fit within annual IRA limits, and the beneficiary must have earned income that year. This option lets you preserve some of the tax-free growth for retirement instead of losing it.

If you withdraw money that was not used for school, the earnings portion is subject to federal income tax plus a 10 percent penalty. Only the earnings are penalized, not your original contributions. For example, if you withdraw $12,000 and $2,000 of that is earnings, you pay income tax and the 10 percent penalty only on the $2,000. This penalty is one reason to be reasonably confident the money will be used for education before you open the account.

Contribution limits and gift tax rules

There is no annual limit on how much you can contribute to a 529 plan, but there is a gift tax consideration. You can give up to $18,000 per year per person (in 2024) without filing a gift tax return or using any of your lifetime gift tax exemption. If you contribute more than that in one year, you must file a gift tax return, though you may not owe tax if you have exemption room available.

Many 529 plans allow "superfunding" — contributing five years' worth of gifts at once ($90,000 per person in 2024) without triggering gift tax, as long as you file a special election on your gift tax return and do not make other gifts to that person that year. This strategy lets you move a large amount into the plan quickly while staying within gift tax rules. Check with your plan to see whether it allows superfunding and what paperwork is required.

These limits explore to each beneficiary separately. You can open multiple 529 accounts for the same child with different plan administrators, and each account counts toward the gift tax limit. If you and your spouse both contribute, you each have your own $18,000 annual limit.

How 529 plans affect financial aid and other considerations

A 529 plan owned by a parent is counted as a parental asset on the Free process for Federal Student Aid (FAFSA), which can reduce the amount of need-based aid your child receives. The impact is usually modest — parental assets are assessed at a lower rate than student assets — but it is worth understanding before you open the account. A 529 owned by a grandparent or other non-parent is not counted on the FAFSA at all, though withdrawals from a grandparent-owned plan may affect aid in other ways.

If you are considering both a 529 and other education savings options like a Coverdell Education Savings Account or a Roth IRA, each has different rules about contribution limits, investment options, and what expenses count. A 529 generally offers the highest contribution limits and the most flexibility for K-12 and college expenses, but comparing your specific situation to other options can help you decide which tool fits best.

Frequently Asked Questions

Can I change the beneficiary if my child does not go to college?

Yes. You can change the beneficiary to another family member — a sibling, cousin, grandchild, or even yourself — without penalty or tax. The money stays in the account and keeps growing tax-free. If you change the beneficiary, make sure the new beneficiary is a family member as defined by the IRS, or the change may be treated as a non-education withdrawal.

What if I invest the money and it loses value?

The value of your 529 account goes up and down with the investments you choose, just like any investment account. If the stock market drops and your balance falls, you have lost money. There is no may provide of growth. This is why many people choose age-based portfolios that become more conservative as college approaches, reducing the risk of a major loss right when they need the money.

Do I have to use the money for the school my child attends?

No. You can use 529 money at any accredited college, university, trade school, or vocational program in the United States or abroad. You can also use it for K-12 private school tuition and student loan repayment. The money follows the student, not a specific school.

What happens to the 529 if I die?

The account does not disappear. It becomes part of your estate and passes according to your will or state law. The beneficiary can continue to use the money for education, or the account owner's estate can change the beneficiary to another family member. There is no automatic tax or penalty when the account owner dies.

Can I withdraw money for room and board if my child lives at home?

Only if your child is enrolled at least half-time at an accredited school. Room and board expenses must be reasonable and related to attendance at that school. If your child lives at home and attends a local college, you can withdraw an amount equal to the school's standard room and board allowance, even if your actual costs are lower.
