How money moves through a 529 account

A 529 plan is a savings account where money grows tax-free as long as you use it for education. You put money in, the account invests it, and when you withdraw it to pay for school, you don't pay federal tax on the growth. The account holder (usually a parent or grandparent) controls the money and decides when and how much to withdraw, even though the account is set up for a specific student.

The mechanics are straightforward: you open an account with a plan sponsor (typically your state's 529 program or a private investment company), choose how to invest the money from the options available, and make contributions whenever you want. The investments grow over time. When the student is ready for college or another education expense, you request a withdrawal, the plan sends the money to you or directly to the school, and you report it on your tax return.

The account stays open as long as you want it to, even if the student doesn't use the money right away. If the student doesn't go to college, you have options: transfer the account to another family member, withdraw the money (paying tax on the growth), or leave it invested longer.

Key Takeaways

  • You contribute after-tax money to a 529, choose from investment options the plan offers, and the account grows tax-free as long as withdrawals pay for education.
  • You control when and how much to withdraw, and you can change the investment mix as the student gets closer to college.
  • Withdrawals for may have access to education expenses (tuition, room and board, books, computers, and up to $35,000 in student loan repayment) avoid federal tax on the growth.
  • If the money isn't used for education, you pay income tax and a 10 percent penalty on the growth only, not on your original contributions.
  • You can transfer unused money to another family member without penalty, which is often a better option than withdrawing it.

Contribution limits and how much you can put in

There is no annual contribution limit on 529 accounts — you can put in as much as you want each year. The only ceiling is the aggregate limit, which is the total amount across all 529 accounts for one student. This limit varies by state and plan, typically ranging from $235,000 to $550,000 per student. The limit is designed to prevent the account from growing so large that it's clearly not for education anymore.

Contributions are made with after-tax money — you don't get a deduction on your federal return. However, 34 states offer a state income tax deduction or credit for 529 contributions, and the amount varies widely. Some states deduct up to $235,000 per year; others cap it at $2,000 or $4,000. A few states offer a credit instead of a deduction, which is often more valuable. Check your state's plan to see what it offers.

You can also use the annual gift tax exclusion to contribute up to $18,000 per person per student in 2024 without filing a gift tax return (or $36,000 if you're married and your spouse agrees). This is a strategy some families use to move money into the account quickly without gift tax consequences, though it doesn't reduce your income tax.

How the money is invested and who chooses

When you open a 529, you select from a menu of investment options. Most plans offer age-based portfolios, which automatically shift from stocks to bonds as the student gets closer to college. You pick the student's expected college year, and the plan rebalances the investments for you. This is the most common choice for hands-off investors.

You can also choose individual investment options — a mix of stock and bond funds, money market funds, or stable value funds — and manage the allocation yourself. Some plans let you pick a single fund. The investment choices vary by plan; a plan run by your state may offer different funds than a plan run by a brokerage firm.

You can change your investment choice once per calendar year, or whenever you change the student listed on the account. If you switch to a different 529 plan, you can move the money through a rollover (moving money between plans for the same student) or a transfer (moving money to a plan for a different family member). Rollovers are tax-free as long as you complete them within 60 days.

Withdrawals for education and what counts

may have access to education expenses are the expenses that let you withdraw money tax-free. They include tuition and fees at any college, university, trade school, or graduate school that is accredited and participates in federal student aid. Room and board counts if the student is at least half-time. Books, supplies, computers, and internet access count. Up to $35,000 per student can be rolled into a Roth IRA to pay off student loans or cover loan repayment, though this counts toward the student's annual Roth contribution limit.

You request a withdrawal from the plan, and the money can be sent to you or directly to the school. If you send it to the school, the school will credit it to the student's account. If you receive it, you're responsible for using it for education — the plan doesn't verify how you spend it, but if you use it for something other than education, you'll owe tax and a penalty on the growth.

Withdrawals for non-may have access to expenses (a car, a computer for a non-education job, living expenses off-campus) are taxed on the growth portion only. Your original contributions come out tax-free. 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 tax and a 10 percent penalty on the $2,000 growth, but not on the $10,000 contribution.

Tax treatment of growth and withdrawals

The money in a 529 grows tax-free at the federal level. You don't pay tax each year on the investment gains, and you don't pay tax when you withdraw for education. This is the main advantage of a 529 over a regular savings account or brokerage account, where you'd owe tax on dividends and capital gains every year.

Some states also exempt 529 growth from state income tax, but not all. A few states tax the growth even though it's federal-tax-free. Check your state's rules if you live in a state with income tax.

When you withdraw for a non-may have access to expense, the growth is taxed as ordinary income at your tax rate, plus a 10 percent federal penalty. The penalty applies only to the growth, not your contributions. Some states also add a state penalty. If you withdraw $2,000 in growth and you're in the 22 percent federal tax bracket, you'd owe $220 in federal tax plus $200 in penalty, for a total of $420.

What happens if the student doesn't go to college

If the student doesn't use the money for education, you have three main options. First, you can transfer the account to another family member — a sibling, cousin, grandchild, or even the account holder's own child. The transfer is tax-free and penalty-free, and it's often the best choice if another family member will use the money for school. The account keeps growing tax-free under the new student's name.

Second, you can withdraw the money. Your contributions come out tax-free. The growth is taxed as ordinary income, and you pay a 10 percent penalty on the growth. If the account grew $5,000 and you're in the 24 percent tax bracket, you'd owe $1,200 in tax plus $500 in penalty on the growth.

Third, you can leave the money invested and wait. The account can stay open indefinitely. If the student later decides to go to college, graduate school, or a trade program, you can withdraw for those expenses. If they don't, you can transfer the money to a younger family member or withdraw it later.

How a 529 affects financial aid and student loans

A 529 account in the parent's name reduces the amount of financial aid the student may receive, because the federal aid formula counts parent assets at a lower rate than student assets. A 529 in the student's name or in a grandparent's name may reduce aid more significantly, depending on the school's aid formula.

The impact varies by school and by how much is in the account. Schools use different methods to calculate aid, and some don't count 529 accounts the same way. If financial aid is important to your family, ask the school's financial aid office how they treat 529 accounts before you open one or make large contributions.

A 529 does not affect federal student loans. You can have a 529 and still borrow through federal loan programs. Some families use a 529 to cover part of college costs and federal loans to cover the rest.

Frequently Asked Questions

Can I use 529 money for room and board?

Yes, room and board counts as a may have access to education expense if the student is at least half-time at an accredited school. You can withdraw money for on-campus housing, or for off-campus housing if the student is at least half-time. The amount is limited to the school's cost of attendance as published by the school's financial aid office.

What happens if I withdraw money and don't use it for education?

You pay income tax on the growth portion at your ordinary tax rate, plus a 10 percent federal penalty on the growth. Your original contributions come out tax-free. Some states also add a state income tax penalty. The plan doesn't verify how you spend the money, but you're responsible for reporting it correctly on your tax return.

Can I change the student on a 529 account?

Yes, you can change the beneficiary to another family member without tax or penalty. Family members include siblings, cousins, aunts, uncles, grandchildren, and in-laws. You can also change it to yourself or the account owner. Changing the beneficiary counts as one of your annual investment changes on some plans.

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

No. You can withdraw money during college, after graduation, or years later for graduate school or trade school. The money stays in the account and keeps growing tax-free until you withdraw it. If the student doesn't go to school, you can transfer it to another family member or withdraw it.

Can I open a 529 for a grandchild?

Yes. Grandparents can open a 529 for a grandchild and contribute to it. The account is treated the same way as a parent-owned account for federal tax purposes. Some states offer a state tax deduction for grandparent contributions, but not all. Check your state's plan to see if grandparent contributions may have access to for a deduction.
