How a 529 Plan Works: Opening an Account and Using the Money

How money flows in and out of a 529 plan

A 529 plan is a savings account where you put in after-tax money, the account grows tax-free, and you withdraw it tax-free when you pay for college or other education costs. You open the account through your state's plan (or another state's plan if you prefer), name yourself as the account owner, and name a student as the beneficiary. Money you deposit sits in investments you choose — usually mutual funds or age-based portfolios that shift from stocks to bonds as the student gets closer to college.

When the student is ready to pay tuition, room and board, books, or other education expenses, you request a withdrawal. The plan sends the money to you, to the school, or directly to a loan servicer if you're using it to repay student loans. The earnings portion of that withdrawal comes out tax-free as long as you use it for what the IRS calls "may have access to education expenses." If you withdraw money for something else, you pay income tax on the earnings plus a 10 percent penalty — the original deposits always come out tax-free regardless.

The account stays open as long as you want it open. You can pause contributions, change investments, or shift the beneficiary to another family member (a sibling, cousin, or even yourself) without tax consequences. The money does not have to be spent by any deadline.

Key Takeaways

• You deposit after-tax money into a 529, choose how it invests, and it grows without annual tax bills — a major advantage over a regular savings account.
• Withdrawals for tuition, room and board, books, computers, and student loan repayment are tax-free; withdrawals for other purposes trigger income tax plus a 10 percent penalty on earnings only.
• You can change the beneficiary to another family member at any time, so unused money does not go to waste if one child does not attend college.
• Each state runs its own plan, but you can open an account in any state's plan regardless of where you live or where the student will attend school.
• Annual contribution limits are high ($18,000 per person per beneficiary in 2024 without gift tax, or $235,000 total per beneficiary depending on your state), so most families will not hit them.

Opening a 529 account and making your first deposit

You open a 529 through your state's plan website or through a brokerage firm that sells plans from multiple states. You will need the student's Social Security number, your own tax ID, and basic information like names and addresses. The account opens in your name as the owner; you control all decisions about contributions, investments, and withdrawals. The student does not need to do anything and does not own the account.

After you open the account, you can deposit money immediately. Most plans accept bank transfers, checks, or automatic monthly transfers. Some plans also let you link a credit card, though you may pay a processing fee. There is no minimum deposit to open most accounts, though some plans have a $25 or $50 minimum for the first contribution. After that, you can add money whenever you want — $50 at a time or $5,000 at a time, whatever fits your budget.

Once the money is in the account, you choose how it invests. Most plans offer age-based portfolios that automatically shift from aggressive (mostly stocks) when the student is young to conservative (mostly bonds) as college approaches. You can also pick individual mutual funds if you want more control. The investment choice is yours to change at any time, though most plans limit you to one change per calendar year unless you switch beneficiaries.

What counts as a may have access to education expense

The IRS allows 529 withdrawals tax-free for tuition and fees at any accredited college, university, trade school, or graduate program in the United States or abroad. Room and board counts if the student is enrolled at least half-time. Books, supplies, and equipment required for the course of study count. A computer or internet access counts if it is used for education. Up to $35,000 per year of unused 529 money can roll into a Roth IRA in the student's name (subject to annual contribution limits), which is a newer option as of 2024.

Student loan repayment also qualifies: you can withdraw up to $35,000 total over the student's lifetime to pay back federal or private student loans in the student's name. This is a one-time election per beneficiary, so plan carefully if you think you might use it.

Expenses that do not count include room and board if the student is not enrolled at least half-time, tuition at K-12 schools (with a $235 per year exception for K-12 private school tuition), and living expenses that are not part of the school's cost of attendance. If you withdraw money for a non-may have access to expense, you owe income tax on the earnings portion plus a 10 percent penalty. The principal (your original deposits) always comes out tax-free.

How the tax-free growth works and what you save

Money in a 529 grows without generating annual tax bills. If you put $10,000 in a regular savings account earning 4 percent, you owe federal income tax on the $400 in interest each year. In a 529, that same $10,000 grows to $10,400 with no tax bill that year. Over 18 years, the difference between paying tax annually and paying nothing compounds significantly — the exact amount depends on your tax bracket, the investment returns, and how much you contribute.

The tax-free growth is the core benefit of a 529. You are not getting a deduction when you put money in (in most states), but you avoid all tax on the growth. For a family in the 24 percent federal tax bracket saving $2,400 per year for 18 years, the tax savings can easily exceed $10,000 depending on investment performance.

Some states also offer a state income tax deduction for 529 contributions. New York, for example, allows you to deduct up to $10,000 per year ($20,000 if married filing jointly) from your state taxable income. A few states have no income tax, so there is no state deduction to claim. Check your state's plan website to see whether a deduction is available where you live.

Changing beneficiaries and what happens to unused money

If one child does not use all the money in a 529, you can transfer the unused balance to another family member's name without tax or penalty. Family members include siblings, cousins, nieces, nephews, parents, grandparents, and even the account owner. You simply notify the plan that you want to change the beneficiary, and the money follows the new beneficiary's education timeline.

This flexibility is one of the biggest advantages of a 529. If your oldest child gets a full scholarship and does not need the money, you can move it to your younger child's account. If neither child attends college, you can move it to a grandchild or use it yourself if you decide to pursue education later.

As of 2024, you can also roll up to $35,000 of unused 529 money into a Roth IRA in the beneficiary's name, subject to annual contribution limits and a requirement that the account has been open for at least 15 years. This option lets you convert education savings into retirement savings if the education money goes unused. The rollover counts toward the student's annual Roth IRA limit, so you cannot put $35,000 in if they only have $7,000 of annual contribution room.

Comparing 529 plans across states

Every state runs at least one 529 plan, and you can open an account in any state's plan regardless of where you live or where the student will attend school. The main differences between plans are the investment options offered, the fees charged, and whether your home state offers a tax deduction for contributions.

Most plans charge an annual expense ratio of 0.3 to 0.7 percent — the cost of managing the mutual funds inside the account. A few plans charge less, and some charge more. Over 18 years, a difference of 0.3 percent in fees can cost you hundreds of dollars in lost growth. Check your state's plan first to see if it offers a deduction; if it does, the tax savings often outweigh slightly higher fees. If your state does not offer a deduction or has high fees, you can shop other states' plans.

Some plans are sold through financial advisors who take a commission, which adds cost. Direct-sold plans, where you open the account yourself online, typically have lower fees. If you are comfortable choosing investments on your own, a direct-sold plan usually costs less over time.

What happens if the student does not attend college

If the student decides not to attend college, you have several options. You can change the beneficiary to another family member at any time. You can roll up to $35,000 into a Roth IRA in the student's name (if the account has been open at least 15 years). You can leave the money in the account and use it later if the student changes their mind. Or you can withdraw the money for any reason — you will just owe income tax and a 10 percent penalty on the earnings portion.

The penalty can feel steep, but it applies only to the growth, not to your original deposits. If you contributed $20,000 and it grew to $25,000, you owe tax and penalty only on the $5,000 in earnings. Your $20,000 comes out tax-free. For many families, this is an acceptable trade-off for years of tax-free growth.

Frequently Asked Questions

Can I use 529 money for room and board if the student lives at home?

No. Room and board is a may have access to expense only if the student is enrolled at least half-time and the expense is part of the school's cost of attendance. If the student lives at home, room and board is not part of the school's official cost, so a 529 withdrawal for it would be non-may have access to and subject to tax and penalty on the earnings.

What if I contribute more than the annual gift tax limit?

The annual gift tax exclusion is $18,000 per person per beneficiary in 2024 (or $36,000 if married filing jointly). If you contribute more, you must file a gift tax return, but you likely will not owe tax — you will just use part of your lifetime gift and estate tax exemption. A tax professional can help you plan large contributions to stay within limits if that matters for your situation.

Do 529 plans affect financial aid?

Yes. Money in a 529 owned by a parent counts as a parental asset on the FAFSA and reduces aid may be able to access by up to 5.64 percent of the account balance. Money in a 529 owned by a grandparent or other non-parent does not count on the FAFSA at all. If financial aid is a concern, talk to a financial aid advisor about account ownership before you open the plan.

Can I withdraw money for graduate school?

Yes. Graduate school tuition, fees, room, and board all count as may have access to expenses. The same rules apply as for undergraduate education — withdrawals for these expenses are tax-free, and withdrawals for other purposes trigger tax and penalty on earnings.

What if the investment I chose performs poorly?

You can change your investment allocation once per calendar year without penalty. If you want to move to a different investment strategy, you can do so. You can also change the beneficiary, which allows you to reset the investment timeline if needed. Poor performance in one year does not lock you in — you have flexibility to adjust.
