A 529 account is a savings account where money grows tax-free as long as you use it for education costs

A 529 account works like a regular savings account, except the federal government does not tax the growth on your money if you spend it on school. You put money in, it sits in investments that grow over time, and when the student needs to pay tuition, room and board, or books, you withdraw it tax-free. The account belongs to the account owner (usually a parent or grandparent), not the student, which gives you control over when and how the money is spent.

The basic mechanics are straightforward: you open an account, deposit money, choose how that money is invested, and later withdraw it to pay the school. The tricky part is understanding which costs count, what happens if the student does not go to college, and how to avoid accidentally triggering taxes. This guide walks you through each step so you know what to expect.

Key Takeaways

  • You can open a 529 account through your state's plan or through a broker, and you can start with any amount — there is no minimum to begin.
  • Money in a 529 grows tax-free only if you use it for school costs like tuition, room and board, books, and computers — not for room and board off-campus in most cases.
  • If the student does not go to college or does not use all the money, you can transfer the account to another family member or withdraw the earnings (but not your original deposits) and pay taxes and a penalty on the earnings only.
  • You choose how the money is invested — usually from a menu of mutual funds — and you can change your investment choice once per year or when the student changes schools.
  • Recent rule changes allow you to roll unused 529 money into a Roth IRA for the student, which opens a new path if college plans change.

Opening an account and choosing a plan

Every state runs its own 529 plan, and you do not have to use your home state's plan — you can open an account in any state's plan. Each state's plan offers different investment options and different fees. Some people choose their home state because it offers a state income tax deduction on contributions, but that is not always the best deal. You can compare plans at websites like Savingforcollege.com, which lists the investment options and fees for each state.

To open an account, you will need your Social Security number, the student's Social Security number, and basic information like names and addresses. You can open an account online in about 15 minutes. You do not need a minimum amount to start — some plans let you open with $25 or even $1. Once the account is open, you can add money whenever you want, and you can set up automatic monthly deposits if that helps you stay consistent.

How to invest the money once it is in the account

When you open a 529, you choose from a menu of investment options — usually mutual funds that hold stocks, bonds, or a mix of both. The plan will offer you age-based portfolios, which automatically shift from riskier investments (more stocks) when the student is young to safer investments (more bonds) as college gets closer. This is the simplest choice for most people because you set it once and do not have to think about it.

You can also pick your own mix of funds if you want more control. The key rule is that you can change your investment choice once per calendar year, or whenever the student changes schools. If you change it more than that, the IRS may treat it as a taxable event. Most people either stick with the age-based option or pick a mix and leave it alone.

What counts as a school expense you can withdraw for

You can withdraw money tax-free for tuition and fees at any college, university, trade school, or graduate school that is accredited and may be able to access for federal student aid. You can also withdraw for room and board if the student lives on campus or in college-approved housing. Books, computers, and required equipment count. Some supplies like a desk or a lamp do not.

The rules are strict about what counts, and the school itself usually tells you what is allowed. If you are unsure whether a cost qualifies, contact the school's financial aid office before you withdraw. If you withdraw money for something that does not count, you will owe income tax on the earnings portion of that withdrawal, plus a 10 percent penalty on the earnings only — not on your original deposits.

Recent changes also allow you to withdraw up to $35,000 over a lifetime to pay down student loans, or to transfer unused money to a Roth IRA for the student. These new options give you more flexibility if the student's plans change.

What happens if the student does not go to college

If the student decides not to go to college or does not use all the money in the account, you have several options. The simplest is to transfer the account to another family member — a sibling, cousin, niece, or even a grandchild — without any tax or penalty. The money stays in the account and keeps growing tax-free for that person's education.

If you do not want to transfer it, you can withdraw your original deposits anytime with no tax or penalty — that money was already taxed when you earned it. If you withdraw the earnings (the growth on your money), you will owe income tax on those earnings plus a 10 percent penalty. For example, if you put in $10,000 and it grew to $12,000, you can withdraw the $10,000 with no penalty, but withdrawing the $2,000 in earnings triggers tax and the penalty.

The new Roth IRA rollover option, available as of 2024, lets you move up to $35,000 of unused 529 money into a Roth IRA for the student (subject to annual contribution limits). This is a way to save the money for retirement instead of losing it to taxes.

How to withdraw money when it is time to pay for school

When the student is ready to start school, you contact your 529 plan and request a withdrawal. You will need to tell the plan the amount, the school's name, and usually the school's federal ID number (the school's financial aid office can provide this). The plan will send the money directly to the school, or to you, depending on what you request.

If the money goes to the school, the school will explore it to tuition and fees first, then room and board, then other costs. If the money comes to you, you are responsible for making sure it is used for school costs. Keep receipts and records in case the IRS ever asks. Most people withdraw money once or twice per year, timed to when bills are due.

Tax deductions and state incentives

Some states offer a state income tax deduction for money you put into a 529 account. This means if you contribute $5,000 to your state's plan, you may be able to deduct that $5,000 from your state taxable income, which lowers your state taxes. Not all states offer this, and the rules vary — some states only give the deduction if you use your home state's plan, while others let you deduct contributions to any state's plan.

Check your state's tax website or ask a tax preparer whether your state offers a deduction and what the rules are. If your state offers a generous deduction, it may be worth using your home state's plan even if another state's plan has lower fees. The federal government does not offer a deduction for 529 contributions, but the tax-free growth is the main federal benefit.

Common mistakes to avoid

The most common mistake is withdrawing money for something that does not count as a school expense, which triggers taxes and a penalty on the earnings. Before you withdraw, confirm with the school that the cost qualifies. Another mistake is changing your investment choice too often — remember you can only change it once per year without tax consequences.

Some people also forget that a 529 account can affect financial aid. The money in the account is counted as an asset when the school calculates how much aid the student should receive, which may reduce the aid they get. This is not a reason to avoid a 529, but it is something to understand. If you are concerned about financial aid, talk to the school's financial aid office about how a 529 will affect your situation.

Finally, do not assume you have to use a 529. If you do not think you will save much, or if you want more flexibility, other options like a Coverdell account or a regular savings account may work better for your situation.

Frequently Asked Questions

Can I open a 529 for a grandchild or a niece?

Yes. The account owner can be anyone — a parent, grandparent, aunt, uncle, or even a friend. The student does not have to be your child. You will need the student's Social Security number and permission from the parent or guardian, but there is no legal requirement that you be related.

What if I contribute too much money and the student does not use it all?

You can transfer the unused balance to another family member without penalty. If you do not transfer it, you can withdraw your deposits anytime tax-free, and withdraw the earnings by paying income tax and a 10 percent penalty on the earnings only. The new Roth IRA rollover option also lets you move up to $35,000 into a Roth for the student.

Does a 529 affect financial aid?

Yes, the money in a 529 is counted as an asset when schools calculate financial aid, which may reduce the aid the student receives. Parent-owned 529s are counted less heavily than student-owned ones. Talk to the school's financial aid office about how a 529 will affect your specific situation.

Can I use 529 money for trade school or graduate school?

Yes. A 529 can be used at any accredited school that is may be able to access for federal student aid, including trade schools, community colleges, and graduate programs. The school does not have to be a four-year university.

What if the student gets a scholarship?

If the student receives a scholarship, you can withdraw an amount equal to the scholarship from the 529 without the 10 percent penalty on earnings — you will still owe income tax on the earnings, but not the penalty. This rule protects you from being penalized for the student's good fortune.
