A 529 is a tax-advantaged savings account for education expenses

A 529 plan is an investment account you open in your name or your child's name, where money grows tax-free as long as you use it for education costs. You put after-tax dollars in, choose how to invest the balance (usually among mutual funds or age-based portfolios), and withdraw it tax-free to pay tuition, room and board, books, computers, and certain student loan repayment. The account has no annual contribution limit set by the IRS, though some states cap how much total value one account can hold—usually $235,000 to $550,000 depending on the state.

The account owner (you, a grandparent, or another adult) controls the money at all times. You decide how much to contribute each year, how to invest it, and when to withdraw. The named beneficiary—usually your child—has no legal claim to the account and cannot access it without your permission. If your child does not go to college, you can change the beneficiary to another family member, withdraw the money and pay taxes plus a 10 percent penalty on the earnings only, or in some cases roll it into a Roth IRA.

Key Takeaways

  • Money in a 529 grows tax-free and can be withdrawn tax-free for tuition, room and board, books, computers, and student loan repayment up to $35,000 per beneficiary lifetime.
  • You choose the investment option when you open the account, and you can change it once per year or when the beneficiary changes.
  • There is no annual contribution limit from the IRS, but contributions over $18,000 per person per year (2024) count against your lifetime gift tax exemption if you do not file a special election.
  • If the beneficiary does not attend college, you can change the beneficiary to a sibling or cousin, roll unused funds into a Roth IRA, or withdraw the money and pay income tax plus 10 percent penalty on earnings.
  • Each state runs its own 529 plan, and you can open an account in any state regardless of where you live or where your child will attend school.

How to open a 529 and choose your investment

You open a 529 through your state's plan website or through a brokerage firm that sells 529s from multiple states. You will need your Social Security number, the beneficiary's Social Security number, and basic information like names and addresses. The entire process takes 10 to 20 minutes online.

When you open the account, you choose an investment option. Most plans offer three types: age-based portfolios that automatically shift from stocks to bonds as your child gets closer to college; static portfolios where you pick a fixed mix of stocks and bonds and it stays the same; and individual fund options where you build your own mix. Age-based is the most common choice for hands-off investors. You can change your investment choice once per calendar year or when you change the beneficiary.

After you open the account, you fund it by linking a bank account and setting up a one-time transfer or automatic monthly contributions. Some plans also accept checks or wire transfers. The money sits in your chosen investment until you withdraw it.

Tax advantages and how they work

The main tax benefit is that earnings grow tax-free. If you put $10,000 into a 529 and it grows to $15,000, you owe no federal income tax on that $5,000 gain when you withdraw it for college. You also owe no state income tax on the earnings in most states, though a few states tax 529 earnings even though they allow the deduction on contributions.

A secondary benefit is the state income tax deduction. Most states let you deduct your 529 contributions from your state taxable income in the year you make them. If you live in New York and contribute $2,500 to a New York 529, you can deduct that $2,500 from your New York income tax return. The deduction amount and income limits vary by state—some have no limit, others cap it at $235 per beneficiary per year or tie it to your income. A few states offer no deduction at all.

The federal gift tax rule is important if you contribute large sums. Contributions up to $18,000 per person per year (2024) are not considered taxable gifts. If you give more than that, you can file a special election to spread the excess over five years, which lets you contribute up to $90,000 per person without triggering gift tax. Married couples can each make this election, doubling the amount. This rule applies to all gifts, not just 529s, but it is often used strategically for 529 funding.

What counts as a may have access to education expense

You can withdraw 529 money tax-free to pay may have access to education expenses at any accredited college, university, trade school, or graduate program. may have access to expenses include tuition and fees, room and board (if the student is at least half-time), books and supplies, computers and internet access, and up to $35,000 lifetime per beneficiary toward student loan repayment.

Expenses that do not count include room and board at a school where the student is less than half-time, transportation to and from school, insurance, and personal expenses like clothing or entertainment. If you withdraw money for a non-may have access to expense, you owe income tax on the earnings portion plus a 10 percent penalty on those earnings.

Starting in 2024, you can also roll unused 529 funds into a Roth IRA in the beneficiary's name, up to $35,000 lifetime, if the account has been open for at least 15 years. This is a way to preserve tax-free growth if your child does not use all the money for college.

What happens if your child does not go to college

If the beneficiary does not attend college, you have several options. The simplest is to change the beneficiary to another family member—a sibling, cousin, niece, nephew, or even a grandchild. The account keeps its tax-free status and investment history. There is no penalty for changing beneficiaries within the family.

You can also withdraw the money. You will owe income tax on the earnings portion at your ordinary tax rate, plus a 10 percent penalty on those earnings. The contributions themselves come out tax-free because they were made with after-tax dollars. For example, if you contributed $20,000 and the account grew to $25,000, you can withdraw all $25,000, pay income tax and the 10 percent penalty only on the $5,000 in earnings, and keep the $20,000 contribution.

A third option, available since 2024, is to roll up to $35,000 of unused funds into a Roth IRA in the beneficiary's name if the account has been open for at least 15 years. This lets the money continue to grow tax-free for retirement instead of education.

How 529 accounts affect financial aid

A 529 owned by a parent counts as a parental asset on the Free Application for Federal Student Aid (FAFSA). Parent-owned 529s reduce financial aid may be able to access by up to 5.64 percent of the account balance per year. A $50,000 parent-owned 529 might reduce aid by roughly $2,820 per year.

A 529 owned by a grandparent or other non-parent relative does not appear on the FAFSA at all, so it does not reduce aid may be able to access. However, when the student withdraws money from a grandparent-owned 529 to pay for college, that withdrawal counts as student income on the following year's FAFSA, which can reduce aid by up to 50 percent of the withdrawal amount. The timing of withdrawals matters if you are trying to minimize aid impact.

Private colleges and some state schools use the CSS Profile form instead of or in addition to the FAFSA, and they may treat 529s differently. Some count grandparent-owned 529s as assets; others do not. Check with the specific school's financial aid office if this applies to you.

Comparing 529 plans across states

Each state runs its own 529 plan, and you can open an account in any state regardless of where you live or where your child will attend school. The main differences are investment options, fees, and state tax deductions. Some plans charge annual account fees of $10 to $25; others charge none. Investment expense ratios (the cost to hold a mutual fund) range from 0.10 percent to over 1 percent per year depending on the fund.

Your home state's plan usually offers a state income tax deduction for residents who invest in that state's plan. If you live in California and open a California 529, you get the California deduction. If you open a New York 529 instead, you typically do not get the California deduction. However, a few states offer a deduction for any 529 plan, regardless of which state runs it. Check your state's tax rules before deciding.

Beyond tax deductions and fees, the investment options matter most. Some plans offer age-based portfolios managed by major investment firms; others offer only static portfolios or individual fund choices. Read the plan's investment menu and fee schedule on the state's 529 website before opening an account.

Frequently Asked Questions

Can I open a 529 for a grandchild or niece instead of my own child?

Yes. You can name any person as the beneficiary, including grandchildren, nieces, nephews, or even unrelated children. The account owner is you; the beneficiary is whoever you name. You control the money at all times.

What if I contribute too much money to a 529?

There is no annual IRS limit on contributions, but contributions over $18,000 per person per year count against your lifetime gift tax exemption. You can file a special election to spread large contributions over five years to avoid this. If you truly over-fund and the account exceeds your state's maximum balance (usually $235,000 to $550,000), you cannot contribute more until the balance drops.

Can I use 529 money for private school before college?

Yes, starting in 2024. You can withdraw up to $35,000 lifetime per beneficiary to pay for tuition at a private or religious elementary, middle, or high school. The money still grows tax-free and withdrawals for may have access to K-12 tuition are tax-free.

Do I have to use the 529 money at a four-year college?

No. You can use it at any accredited college, university, trade school, community college, or graduate program. You can also use it to pay for apprenticeships and certain vocational programs. The school must be accredited and may be able to access to participate in federal student aid programs.

What happens to a 529 if the account owner dies?

The account passes to your estate and is handled according to your will or state law. If you name a successor account owner when you open the account, that person can take over without probate. The beneficiary does not automatically inherit the account; it depends on what your will says or who you named as successor.
