A 529 plan is a special investment account designed to help families save for education. It is named after Section 529 of the U.S. Internal Revenue Code. The biggest benefit is tax savings: money in a 529 plan grows tax-free, and withdrawals are tax-free when used for qualified education expenses.
Whether you are a parent planning for a child’s future, a grandparent who wants to help, or a student thinking about graduate school, understanding 529 plans can help you pay for education with less debt.
How a 529 plan works
- Open an account. You choose a plan, usually offered by a state, and name a beneficiary (the future student).
- Contribute money. You can make one-time deposits or set up automatic monthly contributions. Family and friends can often contribute too.
- Invest. Your money is invested in options you choose, such as age-based portfolios that become more conservative as the student nears college.
- Withdraw for education. When the student enrolls, you take money out to pay qualified expenses, tax-free.
Two types of 529 plans
Education savings plans
This is the most common type. Your contributions are invested, and the value goes up or down with the market. You can use the money at almost any accredited college, university or trade school in the U.S. and many abroad.
Prepaid tuition plans
These plans let you prepay future tuition at participating colleges, usually in-state public schools, at today’s prices. They are offered by only a few states and have more restrictions, but they can protect against rising tuition costs.
What counts as a qualified expense?
Tax-free withdrawals can generally be used for:
- College tuition and fees
- Books, supplies and required equipment
- Computers, internet access and related software used for school
- Room and board for students enrolled at least half-time (up to the school’s cost of attendance figures)
- K–12 tuition, up to an annual federal limit
- Registered apprenticeship programs
- Student loan repayment, up to a $10,000 lifetime limit per beneficiary
Federal law expanded K–12 and some workforce credential uses in 2025, and state tax rules can differ from federal rules. Always confirm current rules with your plan before withdrawing.
Tax benefits
- Federal: earnings grow tax-deferred and are tax-free when used for qualified expenses.
- State: many states offer a state income tax deduction or credit for contributions, often only if you use your own state’s plan.
- Gift tax: contributions count as gifts, but you can contribute up to the annual gift tax exclusion per beneficiary without filing a gift tax return. A special rule lets you “superfund” with five years of contributions at once.
What if the money is not used for education?
If you withdraw money for non-qualified expenses, the earnings portion is subject to income tax plus a 10% federal penalty. Your original contributions come back without tax or penalty. However, there are flexible options before it comes to that:
- Change the beneficiary to another family member, such as a sibling, cousin or even yourself.
- Save it for graduate school or future education.
- Penalty exceptions apply if the student receives a scholarship, attends a U.S. military academy, becomes disabled or dies. In the case of a scholarship, you can withdraw up to the scholarship amount without the 10% penalty, though earnings are still taxed.
- Roth IRA rollover: under current law, unused funds in a 529 account open at least 15 years may be rolled into a Roth IRA for the beneficiary, up to a $35,000 lifetime limit and subject to annual Roth contribution limits and other rules.
Does a 529 plan affect financial aid?
A parent-owned 529 plan is reported as a parent asset on the FAFSA. Parent assets are counted at a much lower rate than student assets, usually a maximum of about 5.64% of the value. This means $10,000 in a parent 529 might reduce aid eligibility by roughly $564 at most. Under recent FAFSA changes, 529 plans owned by grandparents are no longer reported, and withdrawals from them do not count as student income on the FAFSA.
How much should you save?
There is no single right amount. A helpful approach is the “one-third rule”: aim to save about one-third of expected college costs, cover one-third with current income during college, and fill the rest with financial aid and reasonable loans.
Even small amounts help. Saving $100 per month from birth, with a hypothetical average return of 6% per year, could grow to roughly $38,000 by age 18. Investment returns are never guaranteed, but starting early gives your money more time to grow.
How to choose a plan
- Check your state’s plan first for tax deductions or credits.
- Compare fees. Low-cost index fund options can make a big difference over 18 years.
- Look at investment choices, including age-based portfolios.
- Buy directly from the plan instead of through an advisor if you are comfortable choosing investments, as direct-sold plans usually have lower fees.
Tips for parents and students
- Set up automatic monthly contributions, even small ones.
- Ask relatives to contribute to the 529 for birthdays and holidays instead of buying toys.
- Keep receipts for every qualified expense in case of an IRS question.
- Make withdrawals in the same calendar year as the expense.
- Coordinate with education tax credits so you do not use the same expenses twice.
Frequently asked questions

Yes. You can choose almost any state’s education savings plan, though you may lose your own state’s tax benefit.

No. Even a few years of savings can help, and you may still get a state tax deduction.

Yes. Adults can open a 529 plan for themselves to save for graduate school or other education.

The bottom line
A 529 plan is one of the simplest and most tax-friendly ways to prepare for college costs. Start early, contribute regularly and choose a low-fee plan to help your future student borrow less.
