What is a 529 plan and how does it work?
A 529 plan is a tax-free investment account for school costs, from kindergarten tuition to college and apprenticeships.
New to this?
A 529 plan is a savings account for education, named after a section of the tax code. A parent, grandparent or anyone else opens it for a student. The money is invested, grows without federal tax, and comes out tax-free when it pays for tuition, books and other school costs.

Myth
If my kid doesn't go to college, the 529 money is wasted.
Truth
You can switch the account to a sibling or other family member, use it for trade school or an apprenticeship, or roll up to $35,000 into the student's Roth IRA under certain rules.
Worth memorizing
- 1
Growth is tax-free when spent on school.
Earnings skip federal income tax if withdrawals pay qualified costs. Other withdrawals owe income tax plus a 10% penalty on the earnings.
- 2
It covers more than college tuition.
College costs, up to $20,000 a year of K-12 costs, apprenticeships and up to $10,000 of student loan payments can all qualify.
- 3
Leftover money has a way out.
Switch it to another family member, or roll up to $35,000 into the student's Roth IRA after 15 years.
I'd only start a 529 after you have an emergency fund and you're getting any 401(k) match. Your kid can borrow for college. You can't borrow for retirement. Once those are covered, even $50 a month started early adds up.
Do this today
Look up your state's direct-sold 529 plan and check two things: whether contributions get a state tax break, and the total yearly fee for the age-based portfolio. If your emergency fund and retirement match are covered, open it with an automatic $25 to $50 a month.
Practice
1 of 3
Which of these is a qualified 529 expense?
Tuition, required fees, books, and room and board at an eligible school qualify. Cars, trips and credit card bills do not.
2 of 3
Kai's 529 has $20,000: $14,000 he put in and $6,000 of growth. He withdraws it all for a non-school cost. What is the 10% federal penalty?
The penalty applies only to earnings: $6,000 × 10% = $600. The earnings are also taxed as income. The $14,000 he put in comes back tax-free.
3 of 3
What is the lifetime limit on rolling a 529 into the student's Roth IRA?
The lifetime cap is $35,000, and each year's rollover is capped by the IRA contribution limit. The 529 must be open at least 15 years.
Tips
Check your own state first
Many states give a state tax deduction or credit only for their own plan. Compare that benefit against the fees of other states' plans before you pick one.
Buy direct to cut fees
Most states sell a direct plan with no broker. Plans bought through a broker can add sales charges that come out of your growth every year.
Pick an age-based portfolio
These shift from stocks toward safer holdings as the student nears school age, so you don't have to rebalance by hand.
Share a gift link
Many plans let relatives give straight into the account. A birthday gift of $50 invested at age 2 has about 16 years to grow.
A worked example: $150 a month from birth
Lena opens a 529 for her newborn son and sets up $150 a month. She assumes a 6% yearly return before inflation, which is only an assumption.
- Over 18 years Lena makes 216 deposits: $150 × 216 = $32,400 of her own money.
- At an assumed 6% a year, growth adds $25,703, so the account reaches $32,400 + $25,703 = $58,103.
- If the money pays qualified costs, none of the $25,703 is taxed. Returns vary, can be negative, and this is not a promise.
- Monthly deposit$150
- Months to age 18216
- Lena puts in$32,400
- Growth at 6%+$25,703
- Balance at 18=$58,103
- Tax-free growth$25,703

Common mistakes
Skipping your own retirement
Paying into a 529 while missing a 401(k) match gives up free money. Your child has loans and aid. Your retirement has no aid program.
Ignoring fees
A broker-sold plan with sales charges can cost far more over 18 years than a direct plan from the same state. Read the fee table in the offering circular.
Cashing out leftovers too fast
A non-qualified withdrawal owes tax plus a 10% penalty on the earnings. Check a family beneficiary change or a Roth IRA rollover first.
Going deeper
A 529 plan is a state-sponsored investment account for education. The money grows free of federal tax, and withdrawals stay tax-free when they pay for qualified school costs.
Two kinds of 529 plan
Education savings plans are investment accounts you can use at almost any college. Prepaid tuition plans let you buy future tuition credits at today's prices, usually at in-state public schools, with less flexibility.
The tax break is on the way out
Contributions get no federal deduction. The benefit is that earnings grow and come out free of federal income tax when spent on qualified costs. Many states add a deduction or credit for contributions.
A higher K-12 limit
Starting in 2026, you can take up to $20,000 a year per student for K-12 costs, up from $10,000. Covered items now include tuition, books, tutoring and test fees.
Investments can lose value
Savings plans hold mutual funds and ETFs that rise and fall with the market. States do not guarantee them. That is why age-based portfolios get safer as school gets closer.
How a 529 plan works
Each state, plus Washington, D.C., sponsors at least one 529 plan. You open an account, name a student as the beneficiary, and choose investments from the plan's menu. The account holder controls the money, not the student. The account holder and the beneficiary can even be the same person, so adults can save for their own classes.
You put money in after tax. Inside the account it is invested, often in a mix of stock and bond funds. When the student has a qualified cost, you take money out and pay it. If the withdrawal matches qualified costs, none of the growth is taxed by the federal government, and usually not by your state.
What a 529 can pay for
For college, trade school and other eligible schools, qualified costs include tuition, required fees, books, and room and board. The school must be one that can take part in federal student aid programs.
Beyond college, a 529 can pay up to $20,000 a year of K-12 costs per student (tuition, curriculum, books, tutoring and exam fees), fees and equipment for a registered apprenticeship, and up to $10,000 over a lifetime toward the student's or a sibling's student loans. The IRS keeps the full list in Topic 313 and Publication 970.
What happens with money you don't use
If you take money out for something that isn't a qualified cost, the earnings part is taxed as income and gets a 10% federal penalty. The part you put in comes back without tax, since you already paid tax on it. If you took a state deduction, your state may also want it back.
You have better options first. You can change the beneficiary to another member of the same family, like a younger child, a niece or yourself. If the student gets a scholarship, you can usually withdraw up to the scholarship amount without the penalty, though the earnings are still taxed.
There is also a rollover into the student's own Roth IRA. The 529 must have been open at least 15 years, money added in the last 5 years doesn't count, each year's rollover is capped by the IRA limit ($7,500 in 2026), and the lifetime cap is $35,000.
Choosing a plan
Start with your own state's plan, because many states give a deduction or credit only for it. Then look at the fees. Plans can charge enrollment fees, yearly account fees and program and fund management fees. If another state's plan costs much less, the savings can beat your state's tax break over 18 years.
Buy the direct-sold version when you can. The same state's plan sold through a broker often adds sales charges. Read the plan's offering circular (its rule book) before you invest.
Where a 529 fits in your plan
A 529 is a good tool, but it comes after the basics. Build your emergency fund, pay off high-interest debt, and get your full employer retirement match first. Students can borrow for school, but there are no loans for retirement.
A parent-owned 529 counts as a parent asset on the FAFSA, the federal aid form. It can lower need-based aid somewhat. Still, for many families most of an aid package is loans, so every dollar saved is often a dollar the student doesn't have to borrow.
Questions people ask
Who can open a 529 plan?
Almost anyone: parents, grandparents, other relatives, friends, or an adult saving for their own education. Most savings plans take out-of-state savers, though some prepaid tuition plans require you to live in the state.
Is there a limit on how much I can put in a 529?
There's no yearly federal limit, but each plan sets a total cap based on expected school costs. Large gifts can also bring gift tax rules into play; gifts up to $19,000 per person per year in 2026 skip the gift tax return.
Can I use a 529 for private elementary or high school?
Yes. As of 2026, up to $20,000 a year per student can go to K-12 tuition and related costs like books and tutoring. Check your state's rules, since state tax treatment can differ from federal.
Do I have to use my own state's 529 plan?
No. You can use almost any state's savings plan. Your own state may give a tax deduction or credit only for its plan, so compare that benefit with fees elsewhere.
