A 529 account is a tax-advantaged savings plan where you set aside money for a child's education costs, and the money grows without being taxed as long as you use it for school.

The account belongs to you (the parent or guardian), not the child, which means you control when and how the money is spent. You put in after-tax dollars—there's no upfront tax break—but the earnings on that money are never taxed by the federal government, and most states don't tax them either. When you withdraw money to pay for tuition, room and board, books, or other school expenses, those withdrawals come out tax-free.

The name comes from Section 529 of the Internal Revenue Code. Every state runs its own 529 plan, and you don't have to use your home state's plan—you can open an account in any state's plan. The main catch: if you take money out for something other than education, you pay income tax on the earnings plus a 10 percent penalty. That penalty is what makes 529s different from a regular savings account.

Key Takeaways

  • Money in a 529 grows tax-free and comes out tax-free when used for tuition, room and board, books, computers, and other school costs.
  • You control the account and can change the beneficiary to another child in the same family if the first child doesn't use all the money.
  • Contributions are made with after-tax dollars, so you don't get a tax break when you deposit, but some states offer a state income tax deduction for contributions.
  • Withdrawals for non-education expenses trigger income tax on earnings plus a 10 percent penalty, so the account works best when you're confident the money will be used for school.
  • 529 accounts have no income limits, no annual contribution limits, and no age limits—you can open one for a newborn or a teenager.

How the tax advantage actually works

When you put $5,000 into a 529 account, that's your money—you've already paid income tax on it. Over the next few years, that $5,000 grows. If it becomes $6,500, that $1,500 in earnings is where the tax break comes in. Normally, if that money was in a regular savings account or investment account, you'd owe federal income tax on that $1,500 when you withdraw it. In a 529, you don't.

Some states also give you a state income tax deduction when you contribute. New York, for example, lets you deduct up to $10,000 per person per year ($20,000 if you're married filing jointly) from your state taxable income. That means if you contribute $10,000 to a New York 529, you reduce your New York state taxes that year. Other states offer smaller deductions or none at all—it depends on where you live. You can look up your state's rules on the College Savings Plans Network website.

The tax-free growth compounds over time. If you start when your child is born and contribute $2,400 a year for 18 years, and the money averages 5 percent annual growth, you'll have roughly $65,000 in the account—about $43,000 of your own contributions and $22,000 in earnings that was never taxed.

What counts as an education expense

The IRS has a specific list of what you can pay for with 529 money without triggering the 10 percent penalty. Tuition and fees at any accredited college, university, trade school, or graduate school are covered. Room and board counts if the student is at least a half-time student. Books, supplies, and equipment required for school are in. A computer and internet access count. Up to $35,000 per beneficiary can now be rolled over into a Roth IRA if the 529 has been open for at least 15 years—this is a newer rule that lets you move unused money into retirement savings.

What doesn't count: transportation to school, health insurance, student loan repayment (with the exception of up to $35,000 total lifetime), and room and board if the student is less than half-time. If you withdraw money for something not on the list, the earnings portion of that withdrawal is taxed as ordinary income plus the 10 percent penalty. The contributions themselves always come out tax-free, because you already paid tax on them.

Who can open a 529 and for whom

You don't need to be the parent. Grandparents, aunts, uncles, or anyone else can open a 529 for a child. There are no income limits, no age limits for the account owner, and no age limits for the beneficiary—you can open one for a newborn or a 17-year-old. You do need the child's Social Security number to open the account.

There's also no annual limit on how much you can contribute in a single year, but there is a gift tax limit. In 2024, you can give up to $18,000 per person per year without filing a gift tax return. If you're married, you and your spouse can each give $18,000 to the same child, for $36,000 total. If you give more than that in a single year, you have to file a form with the IRS, though you usually won't owe tax—you're just using part of your lifetime gift tax exemption. There's also a special rule that lets you front-load five years of gifts at once ($90,000 per person, $180,000 per married couple) if you file the right election.

You can change the beneficiary to another family member—a sibling, cousin, or even yourself—if the original beneficiary doesn't use all the money. This flexibility makes 529s less risky than they sound, because you're not locked into one child.

The two main types of 529 plans

A prepaid tuition plan lets you lock in today's tuition prices at a specific school or group of schools. You pay now, and the plan covers tuition and fees when the child attends. These plans are offered by some states and a few private universities. The advantage is certainty—you know exactly what you're paying for. The disadvantage is that they only cover tuition and fees, not room and board or books, and if your child doesn't attend the school you chose, you may get back only what you paid in plus a small return, or you may face penalties. These plans are less common now and work best if you're confident about which school your child will attend.

A savings plan is more flexible. You contribute money, choose how to invest it (usually from a menu of mutual funds or age-based portfolios), and the account grows. When your child is ready for school, you withdraw whatever is in the account and use it for any school's tuition, room and board, books, or other expenses. Most people use savings plans because they work at any school and aren't tied to a specific institution or state.

What happens if your child gets a scholarship

If your child receives a scholarship, you can withdraw that amount from the 529 without the 10 percent penalty. You'll still owe income tax on the earnings portion of that withdrawal, but not the penalty. For example, if your child gets a $15,000 scholarship and you withdraw $15,000 from the 529, and $3,000 of that is earnings, you pay income tax on the $3,000 but no penalty. The contributions come out tax-free as always.

This rule exists because the scholarship is covering the education cost, so the 529 money isn't needed for that purpose. You still have to report the withdrawal on your tax return and show proof of the scholarship.

Fees and how to compare plans

529 plans charge fees in different ways. Some charge an annual account maintenance fee (usually $10 to $25). Most charge investment fees—these are the expense ratios of the mutual funds or portfolios inside the plan, typically ranging from 0.15 percent to 1 percent per year. Some plans sold through financial advisors charge sales loads (upfront or back-end commissions), which can be 5 to 6 percent of what you contribute.

Direct-sold plans (where you open the account yourself without an advisor) usually have lower fees than advisor-sold plans. You can compare plans on the College Savings Plans Network website, which lists every state's plan and their fee structures. If you're choosing between your home state's plan and another state's plan, check whether your state offers a tax deduction—that can offset higher fees in another state's plan.

Frequently Asked Questions

Can I use 529 money for private school before college?

Yes. As of 2024, you can withdraw up to $35,000 per beneficiary lifetime from a 529 to pay for tuition at a private elementary, middle, or high school. This is a newer rule. The money still comes out tax-free as long as it's used for tuition.

What if I don't use all the money before my child finishes school?

You can change the beneficiary to another family member—a sibling, cousin, or even yourself—without penalty. You can also roll up to $35,000 into a Roth IRA for the original beneficiary if the account has been open at least 15 years. Any money left over after that can stay in the account, be withdrawn (with tax and penalty on earnings), or be transferred to a family member.

Does a 529 hurt my child's chances of getting financial aid?

It depends on whose name is on the account. If the account is in the parent's name, it counts as a parental asset and reduces aid may be able to access by about 5.6 percent of the account value. If it's in the child's name, it counts as a student asset and reduces aid by about 20 percent. Grandparent-owned 529s don't count against aid at all, though withdrawals from a grandparent account do count as student income in the year they're withdrawn.

Can I open a 529 if I'm not sure my child will go to college?

Yes, but understand the penalty risk. If the money isn't used for school, you'll owe income tax on earnings plus 10 percent. A regular savings account or investment account has no penalty for non-education withdrawals, though you will owe tax on earnings. A 529 makes sense if you're reasonably confident the money will be used for school—college, trade school, or graduate school.
