What a 529 plan is and who can open one

A 529 plan is a tax-advantaged savings account created by a state or educational institution to help families pay for education costs. You open an account, contribute money to it, and the money grows tax-free as long as you use it for may have access to education expenses. The account owner — usually a parent or grandparent — controls the money and decides when and how much to withdraw.

Anyone can open a 529 plan. You do not need to be the parent of the student, and the student does not need to be born yet. Grandparents, aunts, uncles, and even unrelated adults can open an account for a child. The account is owned by whoever opens it, not by the student.

Each state sponsors at least one 529 plan, and some sponsor multiple plans. You can open a plan in any state, regardless of where you live or where the student will attend school. The plan you choose affects the tax benefits you receive — some states offer state income tax deductions only for contributions to their own plan, while others allow deductions for contributions to any plan.

Key Takeaways

  • You can contribute up to $18,000 per person per year to a 529 plan without triggering federal gift tax, or $36,000 per couple, and you can front-load five years of contributions at once.
  • Money grows tax-free inside the account, and withdrawals for may have access to education expenses — tuition, fees, room and board, books, computers, and K-12 tuition — are not taxed at the federal level.
  • Some states offer a state income tax deduction for contributions to their own 529 plan, ranging from a few hundred dollars to several thousand dollars per year depending on the state.
  • If you withdraw money for non-education expenses, you pay income tax on the earnings portion plus a 10 percent federal penalty, though some exceptions exist for unused balances and certain circumstances.
  • You can change the student beneficiary to another family member without penalty, which allows you to move unused money between siblings, cousins, or even to yourself for future education.

Annual contribution limits and gift tax rules

There is no annual limit on how much you can contribute to a 529 plan in a single year, but contributions above a certain amount trigger federal gift tax reporting. The annual gift tax exclusion is $18,000 per person per year (as of 2024; this amount changes yearly). If you are married and file jointly, you and your spouse can each contribute $18,000 to the same student's account without filing a gift tax return, for a total of $36,000 per year.

If you contribute more than $18,000 in a single year, you must file a federal gift tax return (Form 709) with the IRS. Filing the return does not mean you owe tax — it straightforward reports the excess amount. The excess counts against your lifetime gift and estate tax exemption, which is currently $13.61 million per person. Most people never reach that lifetime limit.

529 plans allow a special election called superfunding or front-loading. You can contribute five years' worth of annual exclusion amounts at once — $90,000 per person or $180,000 per couple — and treat it as if you spread it across five years. You must file a gift tax return to make this election, and you cannot make additional gifts to that student for five years without triggering gift tax. This strategy is useful if you have a large sum to invest and want to move money into the plan quickly.

How money grows and tax treatment of earnings

Money inside a 529 plan grows through investment returns — typically through mutual funds, exchange-traded funds, or age-based portfolios that the plan offers. The account owner chooses the investment option when opening the account and can change it periodically. The earnings on your contributions are not taxed each year the way they would be in a regular brokerage account.

When you withdraw money for may have access to education expenses, both your contributions and the earnings come out tax-free at the federal level. may have access to expenses include tuition and mandatory fees at any accredited college, university, or vocational school; room and board if the student is enrolled at least half-time; books and supplies; computers and equipment; and K-12 tuition (up to $35,000 per student, lifetime). Some plans also cover up to $35,000 in student loan repayment per student, lifetime.

The tax-free treatment applies only to the federal level. Some states tax the earnings portion of withdrawals even when used for education, while others do not. Check your state's rules before opening an account.

State income tax deductions and credits

Many states offer a state income tax deduction for contributions to their own 529 plan. The deduction amount and rules vary widely by state. Some states deduct the full contribution amount from your state taxable income; others cap the deduction at a specific dollar amount per year. A few states offer no deduction at all.

For example, New York allows a deduction of up to $10,000 per year ($20,000 if married filing jointly) for contributions to the New York 529 plan. Illinois allows an unlimited deduction. Pennsylvania offers no state income tax deduction. You must check your own state's rules to know what deduction, if any, you can claim.

A handful of states offer a state tax credit instead of a deduction. A credit is more valuable than a deduction because it reduces your tax bill dollar-for-dollar, whereas a deduction only reduces your taxable income. These credits are rare and usually limited to lower-income households.

Withdrawals for education and non-education expenses

When you withdraw money from a 529 plan, the withdrawal is treated as coming out proportionally from your contributions and your earnings. If you withdraw $10,000 and the account is 60 percent contributions and 40 percent earnings, then $6,000 is a tax-free return of your contribution and $4,000 is earnings.

If you withdraw money for a may have access to education expense, the entire withdrawal — contributions and earnings — is tax-free at the federal level. You do not need to prove the expense at the time of withdrawal; the IRS trusts that you are using the money correctly. However, you should keep records of the expenses in case of an audit.

If you withdraw money for a non-education expense, you pay federal income tax on the earnings portion only. You also pay a 10 percent federal penalty on the earnings. For example, if you withdraw $10,000 and $4,000 is earnings, you owe income tax on $4,000 plus a $400 penalty. Your contributions come out tax-free and penalty-free in all cases.

Some withdrawals avoid the 10 percent penalty even though they are not for education. If the student receives a scholarship, you can withdraw the scholarship amount penalty-free (though you still owe tax on the earnings portion of that withdrawal). If the student attends a U.S. military academy, you can withdraw penalty-free. If the student dies or becomes disabled, you can withdraw penalty-free. In 2024, new rules also allow you to roll unused 529 balances into a Roth IRA in the student's name, subject to certain limits and conditions.

Changing the student beneficiary and moving money between accounts

You can change the student beneficiary on a 529 account to another family member without penalty or tax consequences. Family members include the original student's siblings, cousins, parents, grandparents, aunts, uncles, and in-laws. You can also change the beneficiary to yourself if you want to use the money for your own education.

This flexibility means you can open one account for a child, and if that child does not use all the money, you can transfer the unused balance to a sibling's education instead of withdrawing it and paying the penalty. You can also split an account into separate accounts for different family members.

Changing the beneficiary does not trigger gift tax as long as the new beneficiary is a family member. However, if you change the beneficiary to someone who is not a family member, the change is treated as a taxable gift.

Comparing 529 plans across states

Each state's 529 plan has different investment options, fees, and minimum contributions. Some plans charge annual account fees; others do not. Some offer only a handful of investment choices; others offer dozens. Some have no minimum initial contribution; others require $250 or more to open.

The investment options and fees matter because they affect how much your money grows. A plan with high fees or poor investment performance will grow more slowly than a plan with low fees and strong options. However, the state income tax deduction available in your home state often outweighs the benefit of choosing a plan in another state with lower fees.

You can research plans through the College Savings Plans Network, which is run by the National Association of State Treasurers. The site allows you to compare plans side by side, see the investment options each offers, and review fee structures. You can also contact your state treasurer's office directly for information about your state's plan.

Frequently Asked Questions

Can I use a 529 plan for graduate school?

Yes. Tuition and mandatory fees at any accredited graduate or professional school count as may have access to education expenses. Room and board for graduate students also counts if the student is enrolled at least half-time. The same tax-free treatment applies.

What happens if my child gets a full scholarship?

You can withdraw the scholarship amount from the 529 plan penalty-free. You will owe federal income tax on the earnings portion of that withdrawal, but not the 10 percent penalty. You can also leave the money in the account and use it for other education expenses, or change the beneficiary to another family member.

Can I use a 529 plan for private K-12 school tuition?

Yes, up to $35,000 per student, lifetime. This is a relatively recent change. The money must be used for tuition at a private elementary or secondary school, not for other expenses like uniforms or transportation.

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

You have several options. You can change the beneficiary to another family member, including a sibling or cousin. You can roll the unused balance into a Roth IRA in the student's name, subject to limits. Or you can withdraw the money, pay income tax and the 10 percent penalty on the earnings, and keep the contributions tax-free.

Do I lose the state tax deduction if I open a plan in another state?

Most states only offer a deduction for contributions to their own plan. If you live in New York and contribute to a California plan, you typically cannot claim the New York deduction. However, a few states allow deductions for contributions to any plan. Check your state's rules before opening an account.
