What a college savings account actually does

A college savings account is a tax-advantaged container for money you set aside for education expenses. The two main types are 529 plans (named after the tax code section) and Coverdell Education Savings Accounts (ESAs). Money you put in grows tax-free, and when you withdraw it to pay for tuition, room and board, books, or may have access to expenses, you pay no federal tax on the growth. The account itself doesn't pay the school—you do, using the money inside. The tax break is the entire point.

The mechanics are straightforward: you open an account, deposit money, choose how to invest it (usually from a menu of mutual funds or age-based portfolios), and the balance grows over time. When your child is in school, you withdraw what you need. If money is left over or your child doesn't go to college, the rules differ between account types—and this matters more than most people realize before opening one.

Key Takeaways

  • 529 plans and Coverdell ESAs both let money grow tax-free and withdraw tax-free for education, but 529s have much higher contribution limits and fewer income restrictions.
  • You choose how the money is invested from the account provider's menu of options, usually mutual funds or target-date portfolios that shift from stocks to bonds as college approaches.
  • Money withdrawn for non-education expenses is taxed as income plus a 10 percent penalty on the earnings portion, though some exceptions exist for unused balances.
  • A 529 plan is sponsored by your state, but you can use it at any school in the country, and some states offer tax deductions for contributions.
  • The account owner (usually a parent) controls the money and decides when to withdraw it, not the student.

The two main account types and how they differ

529 plans are the larger and more flexible option. Each state sponsors its own plan, though you can open an account in any state's plan regardless of where you live. Contribution limits are high—you can put in up to $235,000 per beneficiary (the student) across all your 529 accounts combined, though the IRS treats large contributions as gifts and may require you to file a gift tax form. There are no income limits: anyone can open one, regardless of how much they earn.

Coverdell ESAs are smaller and more restricted. You can contribute only $2,000 per year per student, and you cannot contribute if your modified adjusted gross income exceeds $110,000 (single) or $220,000 (married filing jointly). The money must be used by the time the student turns 30, or it becomes taxable. Coverdells are less common because the contribution limits are tight and the income restrictions lock out higher-earning families.

Most families use 529 plans. The choice between them usually comes down to whether you have the income to use a Coverdell and whether you want the simplicity of a smaller account or the flexibility of a larger one.

How money grows inside the account

When you open an account, the provider (usually a mutual fund company or your state's plan administrator) gives you a menu of investment options. Common choices include stock mutual funds, bond funds, money market funds, and age-based portfolios—pre-built combinations that automatically shift from stocks (higher growth, more risk) to bonds (lower growth, less risk) as your child gets closer to college age.

You pick one or more options and your deposits are invested there. If you choose a stock fund and the market rises, your balance grows. If the market falls, your balance shrinks. You can change your investment choices once per calendar year, or whenever you change the beneficiary (the student the account is for). Some people set it and forget it; others rebalance as college approaches.

The key tax advantage: the growth is not taxed each year the way it would be in a regular brokerage account. If you invest $10,000 and it grows to $15,000 over ten years, you owe no federal tax on that $5,000 gain—as long as you use it for education. That compounding without annual tax drag is what makes these accounts powerful for long time horizons.

What counts as a may have access to education expense

Withdrawals are tax-free only if you use the money for may have access to education expenses. These include tuition and fees, room and board (if the student is at least half-time), books and supplies, computers and equipment, and up to $35,000 lifetime for student loan repayment (a newer rule). They also cover K-12 tuition (up to $35,000 lifetime per student) if you withdraw from a 529 plan, and apprenticeship program fees.

What doesn't count: transportation, health insurance, personal expenses, and room and board if the student is less than half-time enrolled. If you withdraw money for a non-may have access to expense, the earnings portion is taxed as ordinary income plus a 10 percent penalty. The contribution portion (the money you put in) always comes out tax-free, but the growth is penalized.

This is why the account owner (usually a parent) controls withdrawals. You decide what to pay for and when, and you're responsible for keeping records that show the expense was may have access to. The school doesn't certify it; you do.

What happens if your child doesn't go to college

This is where 529 plans and Coverdells diverge significantly. With a 529 plan, you can change the beneficiary to another family member—a sibling, a cousin, even yourself if you want to go back to school. The money stays in the account and keeps growing tax-free. If no one in the family uses it, you can withdraw the contributions tax-free (but not the growth), or you can withdraw everything and pay tax plus the 10 percent penalty on the earnings only.

A newer rule (effective 2024) lets you roll unused 529 money into a Roth IRA in the beneficiary's name, up to $35,000 lifetime, if the account has been open for at least 15 years. This is a significant shift: money that wasn't used for college can now become retirement savings without penalty.

With a Coverdell ESA, the money must be used by age 30 or it becomes taxable. You can change the beneficiary to a family member, but the same age important date applies to them. This is one reason Coverdells are less popular—the time pressure is real.

How state tax deductions work with 529 plans

Many states offer a tax deduction or credit for 529 contributions, which means you can reduce your state income tax bill by contributing. The amount and rules vary by state. Some states deduct contributions from your taxable income (so a $5,000 contribution might reduce your state taxes by $300 to $500, depending on your tax bracket). Others offer a tax credit, which directly reduces the tax you owe. A few states offer both.

The catch: most states only deduct contributions to their own plan. If you live in New York and contribute to New York's 529, you get the deduction. If you contribute to another state's plan, you don't. A handful of states (like Arizona and Colorado) deduct contributions to any 529 plan, but these are exceptions.

This is worth checking before you open an account. If your state offers a deduction and you're in a moderate tax bracket, the state tax savings can offset the fees and investment costs of the plan in the first few years alone.

Fees and how they affect your balance

529 plans charge fees in two ways: expense ratios on the mutual funds you invest in (typically 0.2 to 1 percent per year, depending on the fund), and sometimes an account maintenance fee (usually $10 to $25 per year, though many plans waive this if your balance is above a certain amount or you set up automatic deposits).

Coverdell ESAs charge similar fund fees but may have higher account maintenance costs because the accounts are smaller and less profitable for providers. Over a ten-year period, a 0.5 percent annual fee on a growing balance can reduce your final amount by several thousand dollars compared to a lower-cost plan.

This is why comparing plans matters. Some states' 529 plans are run by low-cost providers and have competitive fees; others are more expensive. You can research your state's plan and a few others (particularly plans known for low costs, like Nevada's or Utah's) to see what fits your situation.

The role of the account owner versus the beneficiary

The account owner (usually a parent or grandparent) controls the account. You decide how much to contribute, how to invest it, when to withdraw money, and what to spend it on. The beneficiary (the student) has no legal control—they cannot withdraw money or change investments without your permission.

This is actually an advantage if you're concerned about a young adult spending the money on something other than education. The account owner can enforce the intended use. It also means the account doesn't count as the student's asset for financial aid purposes the way a savings account in the student's name would—though it does count as a parental asset, which affects aid calculations differently.

When the student is in school and you decide to withdraw money, you initiate the withdrawal. The funds typically go to you or directly to the school, depending on how you set it up. You're responsible for tracking what the money was used for in case the IRS ever asks.

Frequently Asked Questions

Can I use a 529 plan for private K-12 school, or only college?

You can use a 529 plan to pay for private K-12 tuition (up to $35,000 lifetime per student) without penalty. The money is withdrawn tax-free if used for may have access to K-12 expenses. Public school tuition is not covered. This is a relatively recent change and has made 529 plans useful for families planning private school before college.

What happens to a 529 if my child gets a scholarship?

You can withdraw an amount equal to the scholarship without the 10 percent penalty, though you will owe income tax on the earnings portion of that withdrawal. The contribution portion always comes out tax-free. If your child receives a full scholarship, you can withdraw the scholarship amount penalty-free, but the earnings are still taxed as income.

Does opening a 529 hurt my child's chances of getting financial aid?

A 529 in the parent's name counts as a parental asset and has a modest impact on aid calculations—roughly 5.6 percent of the balance is considered available for education costs. A 529 in the student's name counts as a student asset and has a much larger impact (20 percent). Most families are better off with the account in the parent's name if financial aid is a concern.

Can I open a 529 for a grandchild or niece?

Yes. You can be the account owner for any beneficiary you choose—your grandchild, niece, nephew, or even yourself. The beneficiary doesn't have to be related to you. The contribution limits and tax rules are the same regardless of your relationship to the student.

What if I want to use the money for trade school or apprenticeships instead of a four-year college?

Both 529 plans and Coverdells cover apprenticeship program fees and certain trade school tuition as may have access to education expenses. The money is withdrawn tax-free just as it would be for college. This makes 529 plans useful for families planning non-traditional education paths.
