A 529 account is a tax-advantaged savings plan where you put money in, it grows tax-free, and you withdraw it tax-free to pay for education.

The account is named after Section 529 of the Internal Revenue Code. You open one through your state (most states run their own plans), name a beneficiary—usually a child—and deposit money. That money sits in investments you choose: mutual funds, target-date funds, or stable value options depending on the plan. When the beneficiary goes to college or a may have access to school, you withdraw the money to pay tuition, room and board, books, and fees. The growth and withdrawals are not taxed at the federal level, and most states don't tax them either.

You are not required to use the account for the beneficiary you name. If they don't go to college, you can change the beneficiary to another family member—a sibling, cousin, or even yourself—without penalty. If you withdraw money for something other than education, you pay income tax on the growth plus a 10 percent penalty, but the money you originally deposited comes out tax-free.

Key Takeaways

  • A 529 account grows tax-free and withdrawals for education are not taxed federally or by most states, which is the main advantage over a regular savings account.
  • You can open a plan through your state, choose how the money is invested, and change the beneficiary to another family member if the original one doesn't attend college.
  • Contributions are made with after-tax dollars and are not deductible on your federal return, though some states offer a state income tax deduction for contributions.
  • If money is withdrawn for non-education expenses, you owe income tax on the growth plus a 10 percent penalty, but your original deposits are never penalized.
  • The account owner controls the money and can withdraw it at any time; the beneficiary has no legal claim to the funds.

How contributions and tax deductions work

When you put money into a 529, you are using after-tax dollars—the money has already been taxed as income. The federal government does not let you deduct contributions on your tax return. However, 34 states and the District of Columbia offer a state income tax deduction or credit for contributions to their own 529 plans. The amount varies: some states deduct up to $235 per year per beneficiary, others allow much larger deductions. A few states offer a credit instead, which is worth more than a deduction because it reduces your tax bill dollar-for-dollar rather than reducing your taxable income.

If you live in a state with a deduction and contribute to an out-of-state plan, you typically cannot claim the deduction. This is why many people open an account through their home state even if another state's plan has lower fees. You can check your state's rules on the College Savings Plans Network website, which lists every state plan and its deduction rules.

There is no annual limit on how much you can contribute to a 529, but the IRS watches for gift tax. If you contribute more than $18,000 per person per year (as of 2024; this amount changes annually), you may owe gift tax unless you file a special form. Married couples can each contribute $18,000, so $36,000 total per beneficiary per year without triggering gift tax. There is also a special election that lets you contribute five years' worth of gift-tax-assistance programs in one year—$90,000 per person, or $180,000 for a married couple—if you file the right form.

Investment options and how money grows

When you open a 529, the plan offers you a menu of investment choices. Most plans include mutual funds focused on stocks, bonds, or a mix; target-date funds that automatically shift from stocks to bonds as the beneficiary gets closer to college; and stable value or money market funds that aim for safety over growth. You choose which investments to use, and you can change your allocation once per calendar year or whenever you change the beneficiary.

The money you invest grows based on market performance. If you choose stock-heavy funds and the market rises, your account grows faster. If the market falls, your account value falls too. Target-date funds are popular because they start aggressive when the beneficiary is young and gradually become more conservative as college approaches, so you are less likely to lose money right before you need it.

Some plans also offer a may provide option—usually a contract with an insurance company that promises a set return. These are safer but typically offer lower growth than stock funds over long periods. The trade-off is yours to make based on how much risk you are comfortable with and how many years until the money is needed.

Withdrawal rules and what counts as education expenses

You can withdraw money from a 529 for may have access to education expenses, which include tuition and fees at any accredited college, university, trade school, or graduate program in the United States or abroad. Room and board counts if the student is enrolled at least half-time. Books, supplies, and equipment required by the school also count. Computer and internet access for school purposes are covered. Up to $35,000 per beneficiary can be rolled into a Roth IRA if the account has been open for at least 15 years and the beneficiary is not using the money for college—this is a newer rule that lets you salvage unused 529 money.

K-12 tuition is also covered: you can withdraw up to $235 per year per beneficiary for private or religious school tuition in grades kindergarten through 12. Student loan repayment is covered too: up to $35,000 lifetime per beneficiary can go toward federal or private student loans.

If you withdraw money for something that does not count—a car, a laptop for personal use, or living expenses off-campus—you owe income tax on the growth portion of the withdrawal plus a 10 percent penalty. The original money you deposited comes out tax-free. For example, if you contributed $10,000 and the account grew to $12,000, and you withdraw $12,000 for a non-may have access to expense, you pay income tax and the 10 percent penalty only on the $2,000 in growth.

Fees and plan comparison

529 plans charge fees in two ways: investment management fees (what the mutual funds or target-date funds charge) and plan administration fees (what the state plan charges to run the account). Investment fees typically range from 0.10 percent to 1 percent per year depending on the fund. Administration fees vary widely: some plans charge nothing, others charge $30 to $50 per year or a small percentage of your balance.

Direct-sold plans, where you open an account and manage it yourself, often have lower fees than advisor-sold plans, where a financial advisor helps you choose investments and takes a commission. If you are comfortable picking investments on your own, a direct plan usually costs less over time. The College Savings Plans Network and Morningstar both publish fee comparisons for every state plan.

Some plans offer age-based portfolios at no extra cost—you pick your child's birth year and the plan automatically rebalances from stocks to bonds as they age. Others require you to choose and rebalance manually. If you want hands-off investing, look for plans that offer age-based options with low fees.

What happens if the beneficiary doesn't go to college

If the money is not used for education, you have several options. You can change the beneficiary to another family member—a sibling, cousin, niece, nephew, or even yourself—without any tax or penalty. The account keeps growing under the new beneficiary's name. This is one of the biggest advantages of a 529: if one child gets a scholarship or decides not to attend college, the money is not lost.

You can also roll up to $35,000 of unused 529 money into a Roth IRA for the original beneficiary if the account has been open for at least 15 years. This lets you salvage the money for retirement savings instead of education. The rollover is subject to annual Roth contribution limits, so you cannot move all $35,000 in one year if the beneficiary's income is low.

If you withdraw the money for non-education purposes and do not change the beneficiary or roll it to a Roth, you pay income tax on the growth plus a 10 percent penalty. The penalty is waived if the beneficiary receives a scholarship—you can withdraw the scholarship amount penalty-free, though you still owe income tax on the growth portion.

How a 529 affects financial aid and other benefits

A 529 account owned by a parent is counted as a parental asset on the Free Application for Federal Student Aid (FAFSA). Parent-owned assets reduce financial aid may be able to access by up to 5.64 percent of the asset value per year. If you have $50,000 in a 529 owned by a parent, it could reduce aid by roughly $2,800 per year. This is a real cost to consider if the student will likely need financial aid.

A 529 owned by a student or a grandparent is treated differently. Student-owned accounts reduce aid by up to 20 percent of the asset value, which is much worse. Grandparent-owned accounts do not show up on the FAFSA at all, but withdrawals from a grandparent account count as student income in the year after withdrawal, which can reduce aid by up to 50 percent of the withdrawal amount. If you are trying to maximize financial aid, the timing and ownership of the account matter.

A 529 account does not affect Supplemental Security Income (SSI) or Medicaid if it is owned by a parent and the beneficiary is not the account owner. If the beneficiary owns the account or receives funds from it, it may count as a resource and affect may be able to access for means-tested benefits. If the beneficiary has special needs, an ABLE account may be a better choice than a 529.

Frequently Asked Questions

Can I use 529 money for room and board if my child lives at home?

No. Room and board is only a may have access to expense if the student is enrolled at least half-time and the expense is charged by the school. If your child lives at home, room and board does not count, and withdrawing money for it triggers income tax and the 10 percent penalty on the growth.

What if I open a 529 and then my child gets a full scholarship?

You can withdraw the scholarship amount penalty-free, though you still owe income tax on the growth portion of that withdrawal. You can also change the beneficiary to a sibling or other family member, or roll up to $35,000 into a Roth IRA for the original beneficiary if the account has been open at least 15 years.

Can I use a 529 to pay for my own education?

Yes. You can open a 529 for yourself as the beneficiary and withdraw money for your own tuition, books, and fees at any accredited school. You can also change the beneficiary of an existing account to yourself at any time.

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

No. You can open a plan in any state, even if you do not live there. However, if your state offers a tax deduction for contributions to its own plan, you will usually come out ahead using your home state plan because the tax savings outweigh higher fees in other plans.

What happens to a 529 if the beneficiary dies?

The account owner can change the beneficiary to another family member without penalty. If no one is named as the new beneficiary, the remaining balance is distributed to the account owner or the beneficiary's estate, and income tax plus the 10 percent penalty applies to the growth portion.
