What happens when you open a 529

A 529 account is a tax-advantaged savings account you open in your name (or as a custodian for a child), fund with after-tax money, and use to pay for education expenses. When you open one, you choose a plan—either your state's plan or a plan from another state—then pick investment options within that plan, usually mutual funds or age-based portfolios. The account grows tax-free, and withdrawals for may have access to education expenses (tuition, fees, room and board, books, computers) come out tax-free too.

You do not need to be a resident of a state to use its 529 plan. You do not need the child's Social Security number to open the account, though you will need it before you can fund it. The account is owned by you, the account owner—not the child—which means you control the money and can change beneficiaries to another family member if needed.

Key Takeaways

  • You open a 529 by choosing a plan (your state's or another state's), selecting an investment option, and completing an application online or by mail in about 15 minutes.
  • The account owner is you, not the child, so you keep control of the money and can redirect it to a different family member if the original beneficiary does not attend college.
  • You fund the account by linking a bank account or sending a check; there is no minimum deposit required to open, though some plans have minimums to invest.
  • Contributions are made with after-tax dollars and are not deductible on your federal return, though some states offer a state income tax deduction for contributions to their own plan.
  • The money grows tax-free and withdrawals for may have access to education costs come out tax-free, but non-may have access to withdrawals are taxed as income plus a 10 percent penalty on earnings.

Choosing between your state plan and another state's plan

Every state sponsors a 529 plan, and you can open an account in any of them regardless of where you live. The main reason to choose your state's plan is the state income tax deduction: most states let you deduct contributions to your own state's plan from your state taxable income, usually up to a certain amount per year. A few states—including Arizona, Arkansas, Kansas, Maine, Missouri, Montana, and Pennsylvania—offer the deduction even if you use another state's plan, but that is the exception.

Beyond the tax deduction, compare the investment options and fees. Some plans charge lower expense ratios (the annual percentage you pay to hold the funds), and some offer better-performing portfolios. You can look up your state's plan on its official website, then compare it to plans known for low costs, like those run by Vanguard, Fidelity, or T. Rowe Price. If your state offers no tax deduction and another plan has lower fees or better options, using the other plan usually makes sense.

Opening the account online or by mail

Most 529 plans let you open an account online in 10 to 20 minutes. Go to the plan's website, click the link to open an account, and fill in your name, address, Social Security number, and the beneficiary's name and date of birth. You will choose an investment option—either a single fund or an age-based portfolio that shifts from stocks to bonds as the child gets older. Then you will link a bank account or provide a credit card to fund the account.

If you prefer to open by mail, download the application from the plan's website, print it, sign it, and mail it with a check. This takes longer—usually one to two weeks—but some people prefer it for record-keeping. Either way, you will receive a confirmation with your account number and login credentials.

You do not need the beneficiary's Social Security number to open the account, but you will need it before you can make your first contribution. If the child does not have a number yet, you can open the account and fund it later, or you can apply for a number through the Social Security Administration and provide it when you fund.

Funding the account and making contributions

After you open the account, you fund it by transferring money from your bank account or mailing a check. There is no minimum deposit required to open most 529 accounts, though some plans have a minimum for your first contribution—usually $25 to $250. After that, many plans allow additional contributions as small as $25 or even $10 if you set up automatic transfers.

You can contribute as much as you want in a single year, but there is a federal gift tax limit: contributions over $18,000 per person per year (in 2024) are considered gifts and may trigger gift tax reporting, though not necessarily a tax bill. Married couples can each give $18,000 per beneficiary per year without reporting. Some plans let you make five years of contributions at once ($90,000 per person) without gift tax consequences, which is useful if you want to move a large sum into the account quickly.

Contributions are made with money you have already paid income tax on—they are not deductible on your federal return. However, if you contribute to your state's plan, you may be able to deduct the contribution from your state income tax return. Check your state's rules or ask a tax professional about the deduction limit and whether it applies to you.

Understanding investment options and how your money grows

When you open a 529, you choose how the money is invested. Most plans offer three types of options: individual mutual funds (you pick one or more), age-based portfolios (the plan automatically shifts from aggressive to conservative as the child approaches college), and static portfolios (a fixed mix of stocks and bonds). Age-based portfolios are popular because they require no ongoing decisions—the plan does the rebalancing for you.

The money grows tax-free inside the account. If you invest $5,000 and it grows to $8,000 over five years, you owe no tax on that $3,000 gain. When you withdraw money for may have access to education expenses, the entire withdrawal—contributions plus earnings—comes out tax-free. This is the main tax advantage of a 529.

If you withdraw money for something other than may have access to education expenses, you owe income tax on the earnings portion plus a 10 percent penalty. For example, if you withdraw $8,000 and $3,000 of it is earnings, you pay income tax on the $3,000 plus a $300 penalty. The contribution portion ($5,000) always comes out tax-free. Recent rule changes allow you to roll unused funds to a Roth IRA under certain conditions, which can reduce the penalty risk if the child does not attend college.

What counts as a may have access to education expense

may have access to expenses include tuition and mandatory fees at any accredited college, university, trade school, or graduate school in the United States or abroad. They also include room and board if the student is enrolled at least half-time, books and supplies, computers and equipment, and up to $35,000 in student loan repayment (lifetime limit). K-12 tuition at private schools is also covered, up to $235 per year per student.

Expenses that do not count include room and board for students not enrolled at least half-time, transportation, insurance, and personal expenses. If you are unsure whether an expense qualifies, ask the plan or check the IRS rules on Form 8815 and Publication 970.

Changing the beneficiary or closing the account

If the original beneficiary does not go to college or receives a scholarship, you can change the beneficiary to another family member—a sibling, cousin, niece, nephew, or even yourself—without tax consequences. This is one of the main advantages of owning the account yourself rather than the child owning it. You simply contact the plan and request a beneficiary change; the money stays in the account and continues to grow tax-free.

If you close the account and withdraw money for non-may have access to reasons, you owe income tax on the earnings plus the 10 percent penalty. However, if the beneficiary receives a scholarship, you can withdraw an amount equal to the scholarship without the penalty (though you still owe tax on the earnings). If the beneficiary attends a military academy, you can withdraw without penalty too.

Frequently Asked Questions

Do I need the child's Social Security number to open a 529?

No, you can open the account with just the child's name and date of birth. However, you will need the Social Security number before you make your first contribution. If the child does not have a number yet, you can apply through the Social Security Administration or provide it later when you are ready to fund the account.

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

Yes, you can withdraw up to $235 per year per student for private K-12 tuition. This is a relatively recent change to the rules. Room and board and other expenses at K-12 schools do not count as may have access to expenses.

What happens if my child gets a full scholarship?

You can withdraw an amount equal to the scholarship from the 529 without the 10 percent penalty on earnings. You will still owe income tax on the earnings portion of that withdrawal, but the penalty is waived. Any remaining balance can stay in the account, be rolled to another family member, or be withdrawn (with tax and penalty on earnings).

Can I change my mind and use the money for something other than education?

Yes, but you will owe income tax on the earnings portion plus a 10 percent penalty. For example, if you withdraw $10,000 and $2,000 is earnings, you pay income tax on the $2,000 plus a $200 penalty. The contribution portion always comes out tax-free. Recent rules allow you to roll unused funds to a Roth IRA in some cases, which avoids the penalty.

Does opening a 529 affect financial aid?

Yes, but the impact depends on who owns the account. If you (the parent) own it, it counts as a parental asset and reduces aid may be able to access by up to 5.64 percent of the account value. If a grandparent owns it, the impact is smaller. If the child owns it, the impact is larger. Talk to the college's financial aid office about how a 529 will affect your specific situation.
