What a 529 plan is and why it exists

A 529 plan is a savings account that lets you set aside money for education expenses with a tax break. You put in after-tax dollars, the money grows over time, and when you withdraw it to pay for college, graduate school, or certain other education costs, you don't pay federal income tax on the growth. The account is named after Section 529 of the tax code that created it.

The federal government created these plans to remove one barrier to saving for education: the tax hit. Without a 529, if you saved $10,000 in a regular savings account and it grew to $12,000, you'd owe tax on that $2,000 gain when you withdrew it. In a 529, you don't. That tax savings compounds over years, especially if you start early.

Each state runs its own 529 plan, though you can use any state's plan regardless of where you live or go to school. Some states also offer a state income tax deduction if you use their plan, which is an extra incentive to residents.

Key Takeaways

  • Money in a 529 grows tax-free and withdrawals for education expenses are not taxed federally, though the rules about what counts as an education expense have expanded in recent years.
  • You can open a 529 for anyone—a child, grandchild, or even yourself—and you control the account and when money is withdrawn, not the beneficiary.
  • Each state runs its own plan with different investment options and fees, so comparing plans makes sense even if your state offers a tax deduction.
  • If money is withdrawn for non-education purposes, you pay income tax on the growth plus a 10 percent penalty, though some exceptions exist.
  • Recent rule changes allow you to roll unused 529 money into a Roth IRA under certain conditions, which creates a new option if education plans change.

The two main types of 529 plans

Most 529 plans fall into one of two categories: savings plans and prepaid tuition plans. Savings plans are far more common and work like an investment account—you choose from a menu of investment options (usually mutual funds), contribute money, and the balance grows or shrinks based on market performance. You can withdraw money whenever you need it for education, and you decide how much to take out each semester or year.

Prepaid tuition plans let you lock in today's tuition rates at a specific college or group of colleges. You pay now for future semesters, and the plan covers tuition and fees at those schools no matter how much prices rise. These plans exist in only a handful of states and work best if you know which school your child will attend and want to hedge against tuition inflation. They carry more risk because if your child doesn't attend the covered school, you may get back only what you paid in, with little or no growth.

Most families use savings plans because they're flexible, available in every state, and work with any school.

How to open and fund a 529

Opening a 529 is straightforward. You visit your chosen state's plan website, fill out an process (usually online), and link a bank account to fund it. You'll name the beneficiary—the person whose education the money will pay for—and choose your investment options. The whole process typically takes 15 to 30 minutes. You don't need the beneficiary's permission, and you can change the beneficiary later if plans change.

You can contribute as much as you want in a single year, but federal gift tax rules cap how much you can give without filing a gift tax return. For 2024, you can give up to $18,000 per person per year without triggering that requirement. Married couples can give $36,000 combined. There's also a special election that lets you front-load five years of contributions at once—so $90,000 per person—if you want to move a large sum into the plan quickly.

After you open the account, you can set up automatic monthly contributions, make one-time deposits, or contribute whenever you have money available. There's no minimum contribution to open most plans, though some require $25 to $100 to start.

What counts as an education expense

The original rule was straightforward: 529 money paid for tuition, fees, books, and room and board at any college or university. In recent years, the rules have expanded significantly. You can now withdraw up to $35,000 over a beneficiary's lifetime to roll into a Roth IRA (a different type of retirement account), which is useful if the beneficiary doesn't use all the education money. You can also withdraw money for K-12 tuition at private schools (up to $235 per year per beneficiary as of 2024), apprenticeship programs, and student loan repayment (up to $35,000 lifetime).

Graduate school and professional school tuition also count. Room and board counts only if the student is at least half-time enrolled. Books, supplies, and computers used for school count. Some plans cover room and board for students living off-campus, though the amount is capped at what the school's financial aid office considers reasonable.

Money used for non-education purposes—or for education expenses not on the approved list—triggers income tax on the growth plus a 10 percent penalty. So if your 529 has $15,000 in contributions and $5,000 in growth, and you withdraw $10,000 for a non-education purpose, you'd owe income tax and the penalty on the $5,000 growth portion.

Investment options and fees vary by state

Each state's 529 plan offers a different set of investment choices. Most offer age-based portfolios that automatically shift from stocks to bonds as the beneficiary gets closer to college age—a hands-off option that works well for people who don't want to manage investments. They also typically offer static portfolios (all stocks, all bonds, or a fixed mix) and sometimes individual mutual funds you can pick yourself.

Fees differ significantly between plans. Some charge annual account maintenance fees of $10 to $50. Investment fees—what you pay to own the mutual funds inside the plan—range from under 0.20 percent per year to over 1 percent, depending on the plan and which funds you choose. A few states offer low-cost plans with fees under 0.15 percent, while others charge substantially more. Over 18 years, the difference between a 0.20 percent fee and a 1 percent fee can mean thousands of dollars in extra costs.

You can use any state's plan, so comparing fees makes sense. Many financial websites let you compare plans side by side. If your state offers a tax deduction for residents who use the state plan, you'll want to factor that into your decision—a state tax deduction might outweigh higher investment fees.

Tax benefits and state deductions

The main federal tax benefit is that earnings in a 529 grow tax-free and withdrawals for education are not taxed federally. You don't get a deduction for your contributions—you contribute with after-tax money—but the growth escapes tax entirely if used for education.

Many states offer an additional incentive: a state income tax deduction if you contribute to your state's 529 plan. The amount varies widely. Some states deduct up to $235 per beneficiary per year; others allow much larger deductions. A few states offer no deduction at all. If your state offers a deduction, it usually applies only if you use your state's plan, though a handful of states allow deductions for any plan.

For example, if you live in a state with a 4 percent income tax and a $2,500 annual deduction, contributing $2,500 to your state's 529 saves you $100 in state taxes that year. Over 18 years of contributions, that adds up. Check your state's plan website or a tax professional to learn what deduction your state offers.

What happens if education plans change

If the beneficiary doesn't use all the money—perhaps they get a scholarship, attend a less expensive school, or decide not to go to college—you have several options. You can change the beneficiary to another family member (a sibling, cousin, grandchild, or even yourself) without penalty, and the money continues to grow tax-free. This is the most common solution and keeps the money in the family.

You can also roll up to $35,000 of unused 529 money into a Roth IRA for the original beneficiary, provided the account has been open for at least 15 years and the beneficiary has earned income. This is a relatively new option (available since 2024) and works well if the beneficiary wants to save for retirement instead of education.

If you withdraw money for a non-education purpose, you owe income tax on the earnings plus a 10 percent penalty. The contributions themselves come out tax-free—you only pay tax and penalty on the growth. Some exceptions exist: if the beneficiary receives a scholarship, you can withdraw that amount penalty-free (though you still owe tax on the earnings). If the beneficiary attends a military academy, you can withdraw penalty-free as well.

Frequently Asked Questions

Can I use a 529 for any school?

Yes, 529 money works at any accredited college, university, graduate school, or professional school in the United States, and at many schools outside the U.S. as well. It also works for K-12 private school tuition, apprenticeships, and student loan repayment. Check your plan's website for the full list of approved uses.

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

529 accounts owned by a parent are counted as parental assets on the Free process for Federal Student Aid (FAFSA), which can reduce aid may be able to access. Accounts owned by a grandparent or other relative are treated differently and may have less impact. Talk to a financial aid office about how a 529 might affect your specific situation.

Can I change my mind about which school the money goes to?

Yes. You can change the beneficiary to another family member at any time without penalty or tax. If no one in the family will use the money for education, you can roll up to $35,000 into a Roth IRA for the original beneficiary, or withdraw it and pay tax and penalty on the earnings only.

What if I don't contribute much—is a 529 still worth it?

Even small contributions benefit from tax-free growth over time. If you can contribute $50 to $100 per month for 15 years, the tax savings alone may be worth hundreds of dollars. If your state offers a tax deduction, the benefit is even larger. A 529 costs nothing to open and maintain in most plans, so starting small is a reasonable choice.

Can I open a 529 for myself?

Yes. You can open a 529 for your own education expenses, including graduate school, professional certifications, or career training. The tax benefits work the same way. Some people also open 529s for themselves as a way to save for education they might pursue later.
