529 plans: the tax-free way to save for education

A 529 plan is a tax-advantaged savings account designed to help you pay for education. Money you invest grows without federal tax, and when you withdraw it to pay for qualified education expenses, you pay no federal tax on those withdrawals either. It is the most widely used education savings tool for families in the US, and if you are planning to send children to school here—from kindergarten through college and beyond—a 529 can be a powerful way to build that fund free from federal taxation.

How 529 Plans Work: Tax-Free Growth and Tax-Free Withdrawals

The core appeal of a 529 is straightforward: investment earnings grow free from federal tax, and qualified withdrawals for education are also free from federal tax. You contribute money after tax (you do not get a federal tax deduction for contributions), but once the money is in the account, any growth—interest, dividends, or capital gains—accumulates without triggering federal income tax each year. When you later withdraw money to pay for qualified education expenses, both your contributions and the earnings come out tax-free at the federal level.

This is very different from a regular savings account or investment account. In those accounts, you pay tax on earnings every year as they accrue, which reduces the amount available to reinvest and grow. A 529 defers that tax burden entirely, letting your money compound faster over time.

Qualified Education Expenses: What You Can Pay For

The IRS allows 529 funds to be withdrawn tax-free for a wide range of education costs. For college and trade schools, this includes tuition, fees, room and board (if enrolled at least half-time), books, computers and software used for coursework, and internet access. Graduate school expenses, apprenticeships, and certain credentialing or certification programs also qualify.

K–12 Tuition and Related Costs (Private and Public Schools)

Starting in 2026, you can withdraw up to $20,000 per student per year from a 529 to pay for K–12 tuition at private, public, or religious schools. Beginning in 2025, 529 funds also cover related expenses: textbooks and other instructional materials, online educational courses, tutoring fees (if the tutor is licensed or a subject matter expert, and not a relative), test fees for standardized achievement tests or college admissions exams like the SAT or ACT, and dual enrollment fees for high school students taking college courses.

What Does Not Qualify

Some education-related expenses are not qualified. Room and board costs for students enrolled less than half-time, college application fees, athletic or club fees, transportation or travel to school, and general home schooling materials do not qualify. If you withdraw funds for non-qualified expenses, you pay ordinary income tax plus a 10% federal penalty on the earnings portion of that withdrawal.

Who Can Open a 529 Plan

You do not need to be a US citizen or permanent resident to open a 529 plan, but most plans do require the account owner to be a US citizen or resident alien with a Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN). If you are on an H-1B, L-1, E, or other work visa and have an SSN or ITIN, you can generally open a plan. Grandparents and other relatives can also open accounts.

The beneficiary (the child whose name is on the account) must also have an SSN or ITIN. If your child does not yet have one, you can open the account with yourself as the beneficiary initially, then change it to your child once they receive an SSN or ITIN—this happens automatically after a green card is approved, or can be applied for separately by filing Form W-7 with the IRS.

Contribution Limits and Strategies

There is no federal annual limit on 529 contributions per se, but contributions are treated by the IRS as gifts. In 2026, you can contribute up to $19,000 per year per beneficiary without triggering federal gift tax. If you are married, both spouses can contribute $19,000, for a total of $38,000 per year.

If you want to contribute more than $19,000 in a single year, you can use a strategy called superfunding: contribute up to $95,000 (or $190,000 if married) in one lump sum per beneficiary. You report this over five years on IRS Form 709 but do not owe gift tax. After superfunding, you cannot contribute additional amounts for five years without potentially triggering gift tax, so plan carefully if you choose this approach.

Each state also sets an aggregate (lifetime maximum) balance limit for 529 accounts, which ranges from roughly $235,000 to over $550,000 per beneficiary, depending on the state. This is calculated based on the estimated cost of attending a college in that state and is high enough that most families will not hit this limit.

State Tax Deductions and Credits: The Hidden Advantage

While the federal government does not offer an income tax deduction for 529 contributions, more than 30 states offer a state income tax deduction or credit if you contribute to a 529 plan. This varies significantly by state: some states offer unlimited deductions, others cap the deduction at a few thousand dollars per year, and a handful offer tax credits instead. A few states (such as Arizona, Arkansas, Kansas, Maine, Minnesota, Missouri, Montana, Ohio, and Pennsylvania) allow you to deduct contributions to any state's plan, giving you complete flexibility to choose the lowest-fee plan.

Most states, however, require you to contribute to your own state's 529 plan to receive the tax benefit. A handful of states—including California, Hawaii, and Kentucky—do not offer any 529 tax incentive at all. Because state tax benefits can be substantial (especially in high-tax states), comparing your state's rules before opening an account is worth doing.

Choosing a Plan: In-State vs. Out-of-State

Each state runs its own 529 plan (or plans), but you are not required to use your own state's plan. Most plans are available to residents of all states and to non-residents. The key trade-offs are state tax benefits (which typically apply only to in-state plans) versus lower fees (which some out-of-state plans offer).

Direct-sold 529 plans—those you open directly with the plan provider online or by phone—typically have lower fees (often 0.1% to 0.5% annually). Advisor-sold plans sold through financial advisors sometimes charge higher fees (1.0% or more). The difference in fees on a large balance over many years can cost thousands of dollars, so it is worth investigating.

If you are a recent immigrant or on a visa, check whether your state has residency requirements for opening an account. Six states (Connecticut, Florida, Iowa, Kentucky, New Hampshire, and Ohio) have plans available only to in-state residents, but most other states welcome out-of-state residents. Once you move to another state, you can keep your existing plan or roll it into a new state's plan.

Flexibility: Changing Beneficiaries and Transferring Funds

One of the most valuable features of a 529 is flexibility. You can change the beneficiary to another qualified family member at any time without tax consequences or penalties. This includes siblings, grandchildren, nieces, nephews, cousins, aunts, uncles, and in-laws. For immigrant families with multiple children or uncertain timing, this flexibility is crucial.

If one child does not need all the money saved in their 529 account, you can transfer funds to a younger sibling's account or to another family member's 529 plan without triggering taxes. The transfer process is handled directly by the plan administrator and typically takes a few weeks.

Unused Funds: New Options as of 2024

Recent rule changes have created new ways to use leftover 529 funds. If your child receives a scholarship, graduates, or simply does not need all the saved money, you now have several options beyond transferring to a sibling.

• Roll up to $35,000 (over a lifetime) into a Roth IRA in the beneficiary's name for retirement savings. The 529 account must have been open for at least 15 years, and only funds held for five or more years are eligible. Annual rollover amounts are limited to the current Roth IRA contribution limit (which is $7,500 in 2026), and the beneficiary must have earned income to match the rollover amount.
• Withdraw up to $10,000 per beneficiary to repay their student loans (federal or private), plus an additional $10,000 per sibling to help pay siblings' student loans.
• Leave funds in the account indefinitely; there is no deadline to spend 529 money. Funds can pass to grandchildren and be used for their education later.

If you withdraw funds for non-qualified expenses (not education-related), those earnings will be taxed as ordinary income plus a 10% federal penalty, though contributions themselves can always be withdrawn tax-free.

Record-Keeping and Withdrawal Documentation

To ensure your withdrawals remain tax-free, you must keep careful records that match your 529 withdrawals to qualified education expenses in the same tax year. Save receipts, tuition bills, housing contracts, and bookstore invoices for all education costs paid.

When you withdraw from a 529, the plan will send you IRS Form 1099-Q showing the total distribution and the earnings portion. You must report this on your tax return and match it to the qualified expenses you actually paid. If the IRS audits you, you need to provide documentation that the withdrawn amount was used for qualified expenses. Keep records for at least three years after filing your tax return.

Who Should Open a 529: Is It Right for You?

A 529 is most valuable if you have a multi-year time horizon before education expenses begin, your tax rate is relatively high, your state offers a tax deduction, and you are confident some or all of the funds will be used for qualified education expenses. The longer money stays invested, the more the tax-free compounding benefit grows.

For immigrant families, additional considerations apply. If you are uncertain about your long-term US status or visa situation, discuss this with a tax professional or immigration attorney before opening a 529. In general, if you and your children have SSNs or ITINs and plan to stay in the US for several years, a 529 is an excellent tool. If you are planning to return to your home country soon, the benefits may be less clear, particularly if funds will be used at foreign schools (which can trigger penalties).

Getting Started: Opening Your Account

To open a 529 plan, you will need: your Social Security Number or Individual Taxpayer Identification Number (ITIN); the beneficiary's SSN or ITIN; a US mailing address; and basic information such as name, date of birth, and contact details. You will also select an investment strategy—typically an age-based portfolio that starts with higher-risk investments when the child is young and gradually shifts to safer investments as they approach college age.

Most 529 plans can be opened online in 10–15 minutes and require a minimum initial deposit (often $25–$50). You can then set up automatic monthly contributions or make lump-sum deposits at any time. Your plan administrator (the company that runs your state's or chosen state's 529) will send regular statements and reports showing your account balance and investment performance.

Popular 529 plan platforms include direct-sold plans run by companies like Vanguard, Fidelity, Utah's my529, and state-specific plans available through your state treasurer's office. Compare fees, investment options, and state tax benefits before deciding, and remember that you can switch plans (via a rollover to another plan) if you find a better option later.
