A 529 plan is a tax-advantaged education savings account sponsored by a U.S. state (or, for some prepaid plans, by a college), named for Section 529 of the Internal Revenue Code. Money goes in after tax. Investment growth is not taxed while it stays in the account, and withdrawals are free of federal income tax when they pay for qualified education expenses. A 529 account has an owner, usually a parent or grandparent, who controls the money, and a beneficiary, the student whose education it is meant to fund.

What Is a 529 Plan?

Congress created the federal framework for “qualified tuition programs” in 1996, and states had already begun offering prepaid tuition programs before then. Because each plan is a state program, there is no single “529 account” product: there are dozens of plans with their own rules layered on top of the federal ones.

The original purpose was college costs. Congress has widened that scope several times:

• 2017 (Tax Cuts and Jobs Act): up to $10,000 per year per beneficiary for K-12 tuition at public, private or religious schools.
• 2019 (SECURE Act): expenses of registered apprenticeship programs, plus up to $10,000 in lifetime student loan repayment for the beneficiary and a separate $10,000 for each of the beneficiary’s siblings.
• 2022 (SECURE 2.0 Act): rollovers of unused 529 money into a Roth IRA for the beneficiary, up to a $35,000 lifetime limit, for accounts open at least 15 years.
• 2025 (One Big Beautiful Bill Act): qualified expenses for eligible credentialing programs, a broader list of K-12 costs, and a higher annual K-12 withdrawal limit of $20,000 for taxable years beginning after December 31, 2025.

How a 529 Account Works

Owner and beneficiary

Anyone who is a U.S. resident with a Social Security number or taxpayer ID can generally open an account, and the beneficiary does not have to be a relative. Parents and grandparents are the usual owners. The owner decides how the money is invested, when it is withdrawn and who the beneficiary is. The beneficiary has no legal right to the funds, which is unusual: a contribution counts as a completed gift for gift tax purposes, yet the giver keeps control. Most plans let the owner name a successor owner who takes over if the original owner dies.

One exception is the custodial 529, funded with money from an UTMA or UGMA account. Those assets already belong to the child, so the beneficiary cannot be changed, and control passes to the beneficiary when they reach the state’s age of majority.

Contributions and limits

Contributions are made with after-tax dollars. There is no federal annual contribution limit, but each state sets an aggregate cap per beneficiary, after which the plan stops accepting new money. For 2026, those caps range from $269,000 (North Dakota) to $621,411 (New Hampshire).

Contributions can come from the owner, relatives or friends. Many plans accept recurring transfers from a bank account and, in some cases, payroll deduction.

Investment options

In a savings plan, the money is invested in a menu chosen by the plan, usually mutual funds or ETFs. Typical choices are:

• Age-based or target-enrollment portfolios that start with a higher share of stocks and shift toward bonds and cash as the beneficiary nears school age.
• Static portfolios with a fixed allocation, from all-equity to principal-protected options.
• Individual fund options for owners who want to build their own mix.

You cannot buy individual stocks inside a 529. Federal rules also limit how often you can move existing money between investments: twice per calendar year, or whenever you change the beneficiary. A rollover from one 529 plan to another for the same beneficiary is allowed once every 12 months.

Account values rise and fall with the markets. A savings plan does not guarantee a return, and a balance invested in stocks can fall shortly before tuition is due, which is the risk age-based portfolios try to reduce.

Withdrawals

Every withdrawal is made up of two parts in proportion to the account: your original contributions (basis) and earnings. The contribution portion is never taxed again. The earnings portion is tax-free only if the total withdrawal does not exceed the beneficiary’s qualified expenses for that year. You report this with the Form 1099-Q the plan sends you.

Two practical rules follow. First, match withdrawals to expenses paid in the same tax year; pulling money in January for a bill paid the previous December can break the match. Second, keep receipts and statements showing what the money paid for, because the IRS can ask.

Types of 529 Plans

College savings plans

Savings plans are far more widespread. Most states offer a direct-sold plan you open yourself, and many also offer an advisor-sold plan distributed through brokers, which usually costs more. You are not limited to your own state’s plan; you can open one from any state, and the beneficiary can use it at a school anywhere.

Prepaid tuition plans

A prepaid plan lets you pay now for a set amount of future tuition, measured in semesters, credit hours or “units” tied to a tuition index. If tuition rises faster than your money would have grown elsewhere, the plan works in your favor. Because tuition has risen faster than general prices over long stretches, that has been the main appeal.

The trade-offs are narrower coverage and narrower choice. Many state plans require the owner or beneficiary to be a resident when the account is opened, and if the student attends a non-participating or out-of-state school, the plan typically pays a reduced amount based on its own formula. Some states have closed their prepaid programs to new enrollment.

Tax Advantages of a 529 Plan

Federal income tax. Contributions are not deductible. Earnings are not taxed while invested, and qualified withdrawals are free of federal income tax.

State income tax. Over 30 states plus the District of Columbia offer a deduction or credit for contributions. The details vary widely: some cap the deduction per taxpayer or per beneficiary, some allow unlimited deductions, and some let excess contributions carry forward to later years. In most states that offer a break, it applies only to contributions to the home state’s plan. A handful of states give the break for contributions to any state’s plan. States without an income tax offer no deduction at all.

States can also recapture a deduction if you later roll the money to another state’s plan or take a nonqualified withdrawal, and some states do not follow federal treatment for K-12 or Roth rollover withdrawals.

Coordination with education credits. You cannot use the same expenses for both a tax-free 529 withdrawal and the American Opportunity or Lifetime Learning credit. Families who claim a credit usually pay that slice of tuition from other money and use the 529 for the rest.

Gift tax and the five-year election

Each 529 contribution is a gift to the beneficiary. For 2026, the annual gift tax exclusion is $19,000 per recipient, and the lifetime gift and estate tax exemption is $15 million. Gifts up to the annual exclusion require no gift tax return.

529 plans have a special rule: you can contribute up to five years of annual exclusions at once and elect to spread the gift evenly over five years. In 2026 that means a single donor could contribute $95,000 ($19,000 × 5) to one beneficiary’s account, and a married couple could contribute $190,000, without using any lifetime exemption. The conditions:

• You make the election on Form 709 for the year of the contribution.
• Further gifts to the same beneficiary during the five-year period count against the exclusion for those years, so the donor generally makes no other gifts to that person in the meantime.
• If the donor dies before the five years end, the portion allocated to the remaining years is added back to the donor’s estate.

This front-loading is often called “superfunding.” It gives the entire amount more time to compound, which is why grandparents doing estate planning use it.

What Counts as a Qualified Expense?

At the college and graduate level, qualified expenses at an eligible institution (one that can take part in federal student aid programs) include:

• Tuition and required fees
• Books, supplies and equipment required for enrollment
• Room and board for students enrolled at least half-time, limited to the school’s cost-of-attendance allowance for housing, or the actual charge if living in school housing
• Computers, software and internet access used mainly by the student while enrolled
• Expenses for special needs services a student requires to attend

Beyond college, qualified uses include K-12 tuition and, under the 2025 law, a broader set of K-12 costs within the annual limit; fees, books, supplies and equipment for registered apprenticeship programs; costs of eligible credentialing programs; and student loan repayment up to $10,000 per person over a lifetime.

Common costs that do not qualify include transportation and travel to campus, health insurance or student health fees billed separately, extracurricular activities, and application or testing fees. Room and board for a K-12 student does not qualify either. Paying any of these from a 529 makes that slice a nonqualified withdrawal.

Example of a 529 Plan

Hypothetical, for illustrating mechanics only. A parent opens a savings plan when their child is born and contributes $250 a month for 18 years. Assume an average return of 6% a year, compounded monthly, with no fees or taxes taken into account.

• Total contributed: $250 × 216 months = $54,000
• Projected balance at 18: $250 × [(1.005^216 − 1) ÷ 0.005] ≈ $96,800
• Earnings: about $42,800, roughly 44% of the balance

Now look at what different withdrawals mean, using that 44% earnings share:

1. $20,000 used for tuition and dorm costs in the same year. No federal income tax and no penalty.
2. $10,000 withdrawn to buy a car. About $4,400 is earnings. That amount is added to the recipient’s taxable income (assume a 22% bracket: about $970) plus a 10% additional tax (about $440). The $5,600 of contributions comes back untaxed.
3. The student receives a $10,000 scholarship. The owner can withdraw up to $10,000 without the 10% additional tax. The earnings portion is still subject to income tax.

What Happens to Unused 529 Money

Because the owner controls the account, leftover money has several possible destinations.

Change the beneficiary. You can name a new beneficiary without tax if the new person is a “member of the family” of the current beneficiary. Federal rules define that as:

• A son, daughter, stepchild, foster child, adopted child or a descendant of any of them
• A brother, sister, stepbrother or stepsister
• A father or mother, or an ancestor of either
• A stepfather or stepmother
• A niece or nephew
• An aunt or uncle
• A son-in-law, daughter-in-law, father-in-law, mother-in-law, brother-in-law or sister-in-law
• The spouse of any person above, or of the beneficiary
• A first cousin

A change of beneficiary does not require moving to a new plan. If the new beneficiary is in a younger generation than the old one, gift tax rules can apply.

Keep the money for later. There is no federal deadline for using the funds. The account can wait for graduate school, a later return to study, or a future grandchild.

Repay student loans. Up to $10,000 per person, lifetime, for the beneficiary and each sibling, on qualified federal or private education loans.

Roll into a Roth IRA. The beneficiary can receive up to $35,000 over a lifetime if:

• The 529 account has been open for at least 15 years.
• The amount rolled over excludes contributions (and their earnings) made in the last five years.
• Each year’s rollover stays within the annual Roth IRA contribution limit, reduced by any other IRA contributions the beneficiary makes that year.
• The beneficiary has earned income at least equal to the rollover amount.

Income limits that normally restrict Roth contributions do not apply to these rollovers. The money then follows Roth IRA rules.

Withdraw it. Always possible, at the cost of income tax plus the 10% additional tax on the earnings portion. The penalty is waived for withdrawals after the beneficiary’s death or disability, to the extent of tax-free scholarships, for attendance at a U.S. military academy, and for expenses used to claim an education credit; income tax on earnings still applies in these cases.

How Much Does a 529 Plan Cost?

Costs come in layers:

• Account maintenance fees charged by some plans, typically between $0 and $25 a year, and often waived for residents, for automatic contributions or above a balance threshold.
• Program management fees paid to the state and the plan manager, built into the portfolio’s expense ratio.
• Underlying fund expenses of the mutual funds or ETFs in each portfolio.
• Sales charges and advisor fees in advisor-sold plans, which can include up-front loads or ongoing asset-based fees.

Over 18 years, a difference of a few tenths of a percentage point in annual cost compounds into a meaningful amount, so the total asset-based fee of each portfolio deserves as much attention as its past returns. If your state offers no tax break for its own plan, a lower-cost out-of-state plan may come out ahead.

Effect on Financial Aid

For the FAFSA, a 529 owned by a dependent student or that student’s parent is reported as a parent asset, which is counted at a much lower rate than student assets. Distributions from it are not counted as income. Since the 2024-25 FAFSA, distributions from accounts owned by grandparents or others are no longer reported as student income, which removed a long-standing drawback of grandparent-owned plans. Colleges that use their own aid forms can treat these accounts differently.

Limitations of a 529 Plan

• Restricted use. Earnings spent on anything other than qualified expenses are taxed and usually penalized.
• Limited investment control. A fixed menu, no individual securities and only two reallocations of existing money a year.
• Uneven state treatment. Moving states or switching plans can have state tax consequences.
• Fees. Advisor-sold plans can add sales charges on top of fund expenses.
• Prepaid plan constraints. Narrower coverage, residency requirements and reduced value at non-participating schools.
• Market risk. Savings plan balances can fall, including close to enrollment.

529 Plan vs. Other Ways to Save for Education

529 vs. Coverdell education savings account (ESA). A Coverdell ESA is also a tax-advantaged education account, but contributions are capped at $2,000 per beneficiary per year, contributors face income limits, and money must generally be used by age 30. It has always covered K-12 costs and allows self-directed investments, including individual stocks. A 529 allows far larger contributions and has no age limit.

529 vs. UTMA/UGMA custodial account. A custodial account can be spent on anything that benefits the child, but the assets belong to the child, become theirs at the age of majority, count as student assets for aid, and earnings are taxed each year (partly at the parents’ rate under the kiddie tax).

529 vs. taxable brokerage account. A brokerage account offers any investment and any use with no penalty, but dividends and realized gains are taxed along the way and education spending earns no tax break. It suits money whose purpose is uncertain; a 529 suits money you are confident will go to education.

FAQs

The Bottom Line

A 529 plan fits families who are confident the money will go to education, from K-12 tuition through college, apprenticeships and credentialing programs. Before choosing a plan, compare your home state's tax break against the total fees of each portfolio. Match withdrawals to qualified expenses paid in the same tax year and keep the receipts. Leftover funds can go to another family member, loan repayment or a Roth IRA.
