A 529 account is a tax-advantaged savings account where you deposit money, it grows over time, and you withdraw it to pay for education

A 529 plan is a state-sponsored investment account. You open it, put money in, choose how that money is invested (usually from a menu of mutual funds or age-based portfolios), and the money grows tax-free. When the account owner — typically a parent or grandparent — withdraws money to pay for education expenses, those withdrawals are not taxed at the federal level. The account itself does not earn interest like a savings account; instead, your money is invested in funds that rise and fall in value.

The mechanics are straightforward: you fund the account with after-tax dollars, the investments inside grow without triggering annual tax bills, and withdrawals for may have access to education expenses avoid federal tax. If you withdraw money for something other than education, you pay income tax on the earnings portion plus a 10 percent federal penalty — though some exceptions exist. The account can stay open for decades, and you control when and how much to withdraw.

Key Takeaways

  • You deposit money into a 529 account, choose investments from the plan's menu, and the money grows tax-free until you withdraw it.
  • Withdrawals for may have access to education expenses — tuition, fees, room and board, books, computers, and up to $35,000 in student loan repayment — avoid federal income tax.
  • Money withdrawn for non-education purposes is taxed as income, and the earnings portion also faces a 10 percent federal penalty.
  • Each state runs its own 529 plan, and you can open an account in any state regardless of where you live or where the student will attend school.
  • The account owner, not the student, controls the money and can change the beneficiary to another family member without tax consequences.

How money moves in and out of a 529 account

You open a 529 account through your state's plan or through a plan in another state. You provide your name, the beneficiary's name (usually a child or grandchild), and basic information. Then you fund the account by transferring money from your bank account. There is no federal limit on how much you can deposit in a single year, but contributions above $18,000 per person per year (for 2024) count against your lifetime gift tax exemption — a rule that applies to large gifts to anyone, not just 529 accounts. Most people stay well below this threshold.

Once the money is in the account, you choose how it is invested. Most plans offer age-based portfolios that automatically shift from stocks to bonds as the beneficiary gets closer to college age, or you can pick individual mutual funds. The investments grow or shrink based on market performance. You do not pay federal tax on this growth each year; it compounds tax-free inside the account.

When it is time to pay for education, you request a withdrawal. The plan sends the money to you, to the school, or directly to a loan servicer — depending on what you choose. The withdrawal includes both your original deposits and the investment earnings. If the withdrawal is for a may have access to education expense, the earnings portion is not taxed federally. If it is not, you owe income tax on the earnings and a 10 percent penalty on top.

What counts as a may have access to education expense

may have access to expenses include tuition and mandatory fees at any accredited college, university, trade school, or graduate program. Room and board counts if the student is enrolled at least half-time. Books, supplies, computers, and internet access for school use are covered. Up to $35,000 per beneficiary can be withdrawn over a lifetime to repay student loans — either the beneficiary's own loans or loans taken out by their parents or siblings.

K-12 tuition at private schools is also may have access to, up to $235 per year per beneficiary (for 2024). Apprenticeship programs registered with the Department of Labor count as well. The key is that the expense must be directly tied to education and the student must be enrolled or accepted for enrollment.

Expenses that do not count include room and board if the student is not enrolled at least half-time, transportation, insurance, and personal expenses. If you are unsure whether an expense qualifies, the plan administrator can tell you before you withdraw.

Tax treatment of withdrawals and earnings

The tax advantage of a 529 is that earnings grow without annual tax bills and withdrawals for education are not taxed federally. Your original contributions are never taxed — you put in after-tax money to begin with. Only the earnings portion gets the tax-free treatment, and only if used for may have access to expenses.

If you withdraw money for a non-may have access to expense, you owe federal income tax on the earnings at your ordinary tax rate, plus a 10 percent federal penalty on the earnings. Your contributions come out tax-free. For example, if you deposited $10,000 and the account grew to $12,000, and you withdrew $12,000 for something other than education, you would owe income tax and a 10 percent penalty on the $2,000 in earnings.

Some exceptions to the penalty exist. If the beneficiary receives a scholarship, you can withdraw an amount equal to the scholarship without the penalty (though you still owe tax on the earnings). If the beneficiary attends a U.S. military academy, you can withdraw without penalty. If the beneficiary dies or becomes disabled, the penalty does not explore. A recent rule also allows you to roll unused 529 money into a Roth IRA for the beneficiary under certain conditions.

Who controls the account and what happens if plans change

You, the account owner, control the 529. You decide when to withdraw, how much to withdraw, and where the money goes. The beneficiary — the student — has no legal control over the account, even after turning 18. This is different from a custodial account, where the minor gains control at the age of majority.

If the original beneficiary does not use all the money — for instance, they receive a scholarship or choose not to attend college — you can change the beneficiary to another family member without tax consequences. Family members include siblings, cousins, aunts, uncles, parents, and grandparents of the original beneficiary. You can also roll the remaining balance into a Roth IRA for the beneficiary, subject to annual contribution limits and a five-year lookback rule on the earnings portion.

If you need the money for yourself and withdraw it for a non-may have access to expense, you pay the tax and penalty. There is no loan feature in a 529 — you cannot borrow against the account balance.

How investment choices affect account growth

The investments you choose determine how much your money grows. A 529 account is not a may provide savings vehicle; it is an investment account. If you choose an aggressive portfolio of stocks, your balance could grow significantly over 10 or 15 years, but it could also decline in a market downturn. If you choose a conservative portfolio of bonds, growth is slower but more stable.

Most plans offer age-based portfolios that do the shifting for you. When you open the account, you select the year the beneficiary will start college. The portfolio automatically becomes more conservative as that year approaches, moving from stocks to bonds. This reduces the risk of a market crash right before you need the money.

You can change your investment choices once per calendar year, or whenever you change the beneficiary. Some plans allow more frequent changes if you are rebalancing or responding to a major life event. The investments themselves are mutual funds or similar vehicles offered by the plan; you cannot pick individual stocks.

Differences between state plans and what you can open

Each state runs its own 529 plan, and most states also allow you to open an account in another state's plan. You do not have to use your home state's plan. Some plans have lower fees, better investment options, or state tax deductions for residents. A few states offer a state income tax deduction for contributions to their own plan, but not for contributions to out-of-state plans.

The plan you choose does not affect where the beneficiary can attend school. Money from any 529 plan can be used at any accredited school in the United States or abroad. The plan is just the container; the school does not care which plan funded the account.

Two main types of 529 plans exist: savings plans and prepaid tuition plans. Savings plans are investment accounts like the ones described above. Prepaid tuition plans let you lock in today's tuition rates at participating schools, which protects you if tuition rises sharply. Prepaid plans are less common and come with restrictions on which schools participate and what happens if the beneficiary attends a different school.

Frequently Asked Questions

Can I use 529 money for room and board?

Yes, if the student is enrolled at least half-time. Room and board is considered a may have access to education expense. If the student is enrolled less than half-time, room and board does not count, and withdrawing that amount triggers tax and penalty on the earnings portion.

What happens if my child gets a scholarship?

You can withdraw an amount equal to the scholarship without the 10 percent penalty. You still owe income tax on the earnings portion of that withdrawal, but the penalty is waived. Any remaining balance stays in the account for other education expenses or can be rolled to another family member.

Can I change the beneficiary after opening the account?

Yes, you can change the beneficiary to another family member — including siblings, cousins, or even yourself — without tax consequences. The account owner controls this decision. If you change the beneficiary, the account continues to grow tax-free under the new beneficiary's name.

Do I have to use the 529 money before the student graduates?

No. The money can stay in the account and be used for graduate school, professional school, or other may have access to education expenses. There is no time limit on when withdrawals must happen, as long as the student is enrolled or the money is used for a may have access to expense.

What if I withdraw money and it turns out I didn't need it?

Once you withdraw money, you cannot put it back into the 529 account. If you withdraw for a non-may have access to expense, you owe tax and penalty. If you withdraw for a may have access to expense but later realize you did not need all of it, that money is gone from the account. Plan withdrawals carefully to avoid over-withdrawing.
