What a 529 Plan Actually Is and How It Works

A 529 plan is a tax-advantaged savings account designed specifically for education costs

A 529 plan is a savings account that lets you set aside money for someone's education expenses without paying federal income tax on the growth. You put after-tax dollars in, the money grows over time, and when you withdraw it to pay for college, graduate school, or certain K-12 and vocational costs, you owe no federal tax on the earnings — only on what you originally deposited.

The account is named after Section 529 of the Internal Revenue Code, the federal law that created it. Each state runs its own 529 plan, though you can open an account in any state's plan regardless of where you live or where the student will attend school. The plans are run by investment companies, state agencies, or both working together.

The person who opens the account — usually a parent, grandparent, or other relative — is the account owner and controls the money. The student is the beneficiary. The owner can change the beneficiary to another family member, withdraw the money (though earnings face a tax penalty), or leave it untouched until it is needed.

Key Takeaways

• A 529 plan grows tax-free at the federal level when the money is used for education, and most states also waive state income tax on the earnings.
• You can open a 529 plan in any state, and the money can be used at any accredited college, university, vocational school, or graduate program in the country.
• The account owner controls the money and can change the beneficiary to another family member at any time without tax consequences.
• Contributions are made with after-tax dollars, meaning you do not get a deduction when you deposit the money, though some states offer a state income tax deduction for contributions.
• If money is withdrawn for non-education expenses, the earnings portion is taxed as income and faces a 10 percent federal penalty, though some exceptions exist.

How the tax advantage works

The main benefit of a 529 plan is that the money inside grows without being taxed each year. In a regular savings account or investment account, you owe tax on dividends and capital gains every year, which reduces how much compounds. In a 529, all that growth stays in the account and compounds on itself.

When you withdraw money to pay for education, the earnings come out tax-free at the federal level. Most states also exempt the earnings from state income tax, though a few states tax the earnings even if they are used for education. The original money you deposited — your contributions — was never tax-deductible, so you do not owe tax on it when you withdraw it.

Some states offer an additional benefit: a state income tax deduction for contributions you make to that state's 529 plan. The deduction amount and income limits vary by state. A few states offer the deduction only if you use their plan; others let you deduct contributions to any state's plan. This is separate from the federal tax advantage and can save you money on your state taxes in the year you contribute.

What expenses count as education costs

529 plans cover tuition and fees at any accredited college, university, graduate school, or vocational school. They also cover room and board if the student is enrolled at least half-time, books, supplies, equipment (including a computer), and required fees. Some plans allow you to use up to $35,000 per year for student loan repayment, and recent changes allow a one-time rollover of unused funds to a Roth IRA.

K-12 private school tuition is also covered — you can withdraw up to $235 per year per student for tuition at a private elementary, middle, or high school. Homeschooling expenses do not count. Apprenticeship programs registered with the Department of Labor are covered, but most other vocational training is not unless it is part of a degree program at an accredited institution.

Room and board, books, and supplies must be reasonable and required by the school. If you withdraw money and it turns out the expense did not count, the earnings portion of that withdrawal is taxed as income and faces a 10 percent federal penalty.

Who can open a 529 plan and contribute

Anyone can open a 529 plan — parents, grandparents, aunts, uncles, or even the student themselves. There is no age limit for the account owner, and there is no income limit. You do not have to be related to the student to open an account for them, though some plans require a Social Security number or tax ID to verify the relationship.

There is no annual limit on how much you can contribute to a 529 plan, but contributions are considered gifts for tax purposes. If you contribute more than $18,000 per person per year (the 2024 annual gift tax exclusion), you may have to file a gift tax return, though you will not owe tax unless you exceed your lifetime gift tax exemption. Some people use a special election to spread a large contribution over five years to avoid triggering gift tax reporting.

Multiple people can contribute to the same 529 plan for the same student. Grandparents, parents, and other relatives can all fund the same account. The account owner controls how the money is invested and when it is withdrawn, regardless of who contributed it.

What happens if the money is not used for education

If you withdraw money from a 529 plan and do not use it for education, the earnings portion is taxed as ordinary income and faces a 10 percent federal penalty. The contributions themselves are not penalized — you can always withdraw what you put in without tax or penalty. Only the growth is taxed and penalized.

There are a few exceptions to the penalty. If the student receives a scholarship, you can withdraw that amount penalty-free (though you still owe tax on the earnings). If the student attends a U.S. military academy, you can withdraw penalty-free. If the student becomes disabled or dies, the account can be closed penalty-free. Recent rules also allow a one-time rollover of unused funds to a Roth IRA in the beneficiary's name, up to certain limits.

If you do not use all the money before the student finishes school, you can change the beneficiary to another family member — a sibling, cousin, or even your own child — without any tax or penalty. This makes 529 plans flexible for families with multiple children or when education plans change.

How 529 plans affect financial aid

Money in a 529 plan counts as an asset when you fill out the Free process for Federal Student Aid (FAFSA). Parent-owned 529 plans are assessed at up to 5.64 percent toward the expected family contribution, meaning they reduce financial aid may be able to access more than other assets. Student-owned 529 plans are assessed at 20 percent, which reduces aid more significantly.

Grandparent-owned 529 plans do not appear on the FAFSA at all, so they do not affect aid may be able to access while the student is in school. However, when the grandparent makes a withdrawal to pay for education, that withdrawal counts as untaxed income to the student in the following year, which can reduce aid may be able to access the next year. This timing matters if the student will be in school for multiple years.

The impact on aid varies by school. Some schools use the FAFSA to determine aid; others use their own financial aid form and may count 529 plans differently. It is worth asking the financial aid office how they treat 529 plans before you open one.

The difference between 529 plans and other education savings options

A 529 plan is not the only way to save for education. A Coverdell Education Savings Account (ESA) also grows tax-free and can be used for K-12 and college expenses, but it has a $235 annual contribution limit and income limits for who can open one. A regular custodial account in the student's name has no contribution limits but offers no tax advantage. A Roth IRA can be used for education without the 10 percent penalty, though it was designed for retirement.

The main advantage of a 529 plan over these options is the high contribution limit and the fact that the account owner retains control of the money. With a custodial account, the money legally belongs to the student once they reach age of majority. With a 529, you keep control and can change the beneficiary if plans change.

The main disadvantage is that 529 plans reduce financial aid may be able to access (unless owned by a grandparent) and offer no tax deduction at the federal level, though some states do. If you expect to receive substantial financial aid, a Coverdell ESA or a regular savings account might be a better choice.

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 must be reasonable and required by the school. If the student lives at home and commutes, room and board does not count. The school's financial aid office can tell you the allowance they use for room and board costs.

What if I open a 529 and the student decides not to go to college?

You can change the beneficiary to another family member — a sibling, cousin, niece, or nephew — without tax or penalty. You can also roll the money into a Roth IRA in the student's name, up to certain limits. If you withdraw the money for non-education purposes, the earnings are taxed and penalized, but your contributions come out tax-free.

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

No. You can open an account in any state's plan, regardless of where you live or where the student will attend school. Some states offer a tax deduction only for contributions to their own plan, so check your state's rules before you choose. Otherwise, you can compare plans based on investment options and fees.

Can a grandparent open a 529 for a grandchild?

Yes. Grandparent-owned 529 plans do not appear on the FAFSA, so they do not reduce financial aid may be able to access while the student is in school. However, grandparent withdrawals count as untaxed income to the student the following year, which can affect aid in year two and beyond. This timing matters for multi-year education programs.

What happens to a 529 if the student gets a scholarship?

You can withdraw the scholarship amount penalty-free, though you still owe tax on the earnings portion of that withdrawal. The contributions come out tax-free. If the scholarship covers all education costs, you can withdraw the entire balance, pay tax on the earnings, and avoid the 10 percent penalty.
