How a 529 Plan Works and What It Covers

A 529 plan is a tax-advantaged savings account designed specifically for education costs

A 529 plan is an investment account that lets you save money for education expenses without paying federal income tax on the growth. You contribute after-tax dollars, but the money inside grows tax-free, and withdrawals for education costs are not taxed either. The account is named after Section 529 of the Internal Revenue Code, the federal law that created it.

Each state sponsors at least one 529 plan, though you can use any state's plan regardless of where you live or where the student will attend school. The plans are run by financial institutions under state oversight. You open an account, choose investments (usually mutual funds), and add money over time. When the student is ready for school, you withdraw money to pay tuition, fees, room and board, and other education expenses.

The main trade-off is that money withdrawn for non-education purposes is taxed as income plus a 10 percent penalty on the earnings portion. This restriction is why 529 plans work best when you are fairly confident the money will be used for school.

Key Takeaways

• Money in a 529 plan grows tax-free and can be withdrawn tax-free for education expenses at any accredited college, university, trade school, or graduate program.
• Each state runs its own 529 plan or plans, and you can open an account in any state's plan regardless of where you live.
• Annual contribution limits are high (you can give up to $18,000 per person per year in 2024 without triggering gift tax), and some states offer state income tax deductions for contributions.
• If the money is not used for education, withdrawals are taxed as income plus a 10 percent penalty on the earnings, though recent rules allow tax-free transfers to Roth IRAs in some situations.
• The account owner controls the money and can change the beneficiary to another family member, so unused funds do not have to be forfeited.

How contributions and tax treatment work

You contribute money to a 529 account with after-tax dollars — meaning you do not get a federal deduction for the contribution itself. However, some states offer a state income tax deduction or credit for 529 contributions, which varies by state. A few states deduct contributions from state taxable income dollar-for-dollar; others offer a partial deduction or credit. If you live in a state with no income tax, there is no state deduction to claim.

The money you contribute is invested in the mutual funds or other options the plan offers. Any growth — dividends, capital gains, interest — accumulates tax-free inside the account. You never pay federal tax on that growth as long as the money stays in the plan. When you withdraw money for education expenses, both your contributions and the growth come out tax-free.

The annual contribution limit is not a limit on how much you can give in total, but rather how much you can give per person per year without filing a gift tax return. In 2024, you can give up to $18,000 per person per year without triggering gift tax reporting. Married couples can give $36,000 per year per beneficiary. These amounts change annually with inflation.

What education expenses the plan covers

A 529 plan covers tuition and mandatory fees at any accredited college, university, graduate school, or trade school in the United States or abroad. It also covers room and board if the student is enrolled at least half-time. Books, supplies, equipment, and computers required for school are covered. Up to $35,000 per year (with a lifetime limit of $235,000) can be used for student loan repayment — either the beneficiary's own loans or parent PLUS loans taken out by the account owner.

Starting in 2024, up to $35,000 of unused 529 money can be rolled into a Roth IRA in the beneficiary's name, subject to income limits and other rules. This option lets families recover some of the tax benefit if the student does not use all the money for school.

Expenses that do not count include room and board for students attending school less than half-time, student health insurance, transportation, and personal expenses. If you withdraw money for these costs, the earnings portion is taxed as income plus a 10 percent penalty.

The difference between prepaid and savings plans

Most states offer two types of 529 plans: a savings plan and a prepaid tuition plan. A savings plan works like a regular investment account — you choose how to invest the money, and the value rises or falls with the market. A prepaid tuition plan lets you lock in today's tuition rates at participating colleges, usually in-state public universities. If tuition rises, your prepaid credits rise with it. If the student attends a different school or does not go to college, you get the money back, though usually with limited growth.

Savings plans are more flexible because you can use the money at any accredited school and for any covered education expense. Prepaid plans offer certainty about tuition costs but limit where the money can be used and may not cover room and board or other expenses. Most families use savings plans because they offer more control and work with any school.

Who can open and control a 529 account

Anyone can open a 529 account — parents, grandparents, aunts, uncles, or even the student themselves. The person who opens the account is the account owner and controls all decisions: how the money is invested, when withdrawals happen, and who the beneficiary is. The beneficiary is the student whose education the money is meant to cover, but the beneficiary does not control the account.

This distinction matters because it means the account owner can change the beneficiary to another family member (a sibling, cousin, or even the account owner's own child born later) without penalty. If one child does not use all the money, you can transfer it to another child's education instead of losing the tax benefit. Family members are defined broadly and include spouses, children, grandchildren, parents, and siblings.

The account owner is also responsible for reporting the account on financial aid forms (FAFSA) if the student is explore for federal aid. Parent-owned 529 accounts affect financial aid less than student-owned accounts, which is one reason parents often open these accounts rather than grandparents.

How 529 plans affect financial aid and other considerations

A 529 account owned by a parent is counted as a parent asset on the FAFSA and reduces financial aid may be able to access by up to 5.64 percent of the account value. A 529 account owned by a grandparent is not reported on the FAFSA at all, but distributions from a grandparent-owned 529 are counted as student income in the year they are withdrawn, which can reduce aid by up to 50 percent of the distribution. A 529 owned by the student is counted as a student asset and reduces aid by up to 20 percent of the account value.

This means the timing of withdrawals matters if the student is receiving need-based aid. Withdrawing in the student's senior year of high school or after graduation has less impact than withdrawing during the freshman or sophomore year of college.

529 accounts do not affect Social Security, Medicaid, or Supplemental Security Income (SSI) benefits if the account is owned by a parent or grandparent. However, if the beneficiary is disabled and receiving SSI, a large 529 account could affect may be able to access, so families in this situation should consult a special needs planner.

Comparing 529 plans across states

Every state offers at least one 529 plan, but the plans differ in investment options, fees, and state tax benefits. Some states offer only a savings plan; others offer both savings and prepaid plans. Investment options range from age-based portfolios (which automatically shift from stocks to bonds as the student gets closer to college) to individual mutual funds you can choose yourself.

Fees vary significantly. Some plans charge an annual program fee plus underlying fund fees; others charge only the fund fees. Direct-sold plans (where you buy directly from the state) typically have lower fees than advisor-sold plans (where you buy through a financial advisor). Over 18 years, a difference of 0.5 percent in annual fees can reduce your account balance by thousands of dollars.

State tax deductions also vary. Some states offer a deduction only for contributions to their own plan; others allow deductions for contributions to any state's plan. A few states offer no deduction at all. If you live in a state with a generous deduction, that state's plan may be worth using even if another state's plan has lower fees.

Frequently Asked Questions

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

Yes. Up to $35,000 per year can be withdrawn tax-free for tuition at private elementary, middle, or high schools. This is a relatively recent change, so check your specific plan to confirm it offers this option, as some older plans may not have updated their rules yet.

What happens if my child gets a scholarship?

You can withdraw an amount equal to the scholarship from the 529 without penalty. You will owe income tax on the earnings portion of that withdrawal, but not the 10 percent penalty. The rest of the money stays in the account and can be used for other education expenses or transferred to another family member.

Can I change the beneficiary if my child decides not to go to college?

Yes. You can change the beneficiary to another family member — a sibling, cousin, niece, nephew, or even a grandchild — without penalty. The money keeps its tax-free status in the new beneficiary's name. If no family member will use it for education, you can roll up to $35,000 into a Roth IRA for the original beneficiary.

Do I have to use the plan from my state?

No. You can open a 529 account in any state's plan, regardless of where you live or where the student will attend school. However, if your state offers a tax deduction for contributions to its own plan, using your state's plan may provide a tax benefit that other states' plans do not.

What if I withdraw money for something other than education?

The contribution portion comes out tax-free, but the earnings portion is taxed as ordinary income plus a 10 percent penalty. For example, if you contributed $10,000 and the account grew to $15,000, you could withdraw $10,000 with no tax or penalty, but withdrawing the remaining $5,000 would trigger income tax plus a 10 percent penalty on that $5,000.
