College Will Cost $400,000 by 2044. The Only Account That Grows Tax-Free to Pay for It Has a New Rule That Changes Everything.

WASHINGTON, June 8, 2026 —

The most expensive single purchase most American families make — more than a car, sometimes more than a house — is not something they choose after comparison shopping. It chooses them. A child is born, grows up, and arrives at eighteen in front of a college application. Whatever that college costs in that year, the family pays it — from savings, from loans, from whatever combination of resources they assembled in the years before that moment arrived.

The 529 college savings plan is the account the tax code created specifically for that moment. It is the only savings vehicle that grows entirely free of federal tax and withdraws entirely free of federal tax when the money is spent on qualified education expenses. And a rule change that took effect in 2024 — and is now fully operational in 2026 — removed the last significant objection to using it aggressively.

What a 529 Plan Actually Is — and the Three Tax Advantages Most Families Never Fully Use

A 529 plan is a state-sponsored investment account specifically designed to pay for education expenses. Every state operates at least one plan, and account holders can invest in any state’s plan regardless of where they live or where the beneficiary attends school. Contributions are made with after-tax dollars. The balance is invested in mutual funds or age-based portfolios that shift from stock-heavy to bond-heavy as the beneficiary approaches college age. All earnings, dividends, and capital gains accumulate without annual taxation. Qualified withdrawals — for tuition, fees, room and board, books, computers, and certain other expenses — are completely free of federal income tax.

The first tax advantage is the state deduction. Thirty-seven states provide a state income tax deduction or credit for 529 contributions made to their state’s plan. In New York, contributions up to $5,000 per year for single filers and $10,000 for married couples are deductible from state taxable income. At New York’s 6.85% top marginal state rate, a $10,000 contribution produces a $685 immediate state tax reduction. In Virginia, the same $10,000 contribution reduces state taxes by $575 at the 5.75% rate. These deductions apply in the year of contribution and compound in value when the federal tax-free growth is factored in over the full investment horizon.

The second is tax-free growth. A $10,000 529 contribution made when a child is born in 2026, invested in a diversified portfolio earning a 7% average annual return, grows to approximately $34,000 by the time the child is 18 — with every dollar of the $24,000 in earnings completely free of federal tax. The same $10,000 in a taxable brokerage account, with the same 7% return and a 22% federal tax on annual gains, grows to approximately $27,000 — a $7,000 difference that represents the tax-free growth advantage alone.

The third is the gift tax exclusion amplifier. The IRS allows a technique called superfunding — or 5-year gift tax averaging — that permits a contributor to make a lump-sum 529 contribution of up to five times the annual gift tax exclusion in a single year and treat it as if it were spread over five years. In 2026, the annual gift tax exclusion is $19,000 per recipient. A grandparent can contribute $95,000 to a 529 for a grandchild in a single year — removing it from their taxable estate immediately — while treating it as five $19,000 annual gifts for gift tax purposes. A married couple can superfund $190,000 at once.

The Cost That Justifies the Urgency

The College Board’s 2025-26 Trends in College Pricing report put the average annual cost of attending a four-year public university — tuition, fees, room, and board — at $28,840. For a private nonprofit four-year institution, the figure is $60,420. These are averages. Selective private universities consistently run above $80,000 per year. The four-year total at an average private college today exceeds $240,000.

College costs have risen at an average rate of approximately 4% annually for the past two decades — faster than general inflation. Applied to today’s averages, a child born in 2026 who enters college in 2044 faces projected costs of approximately $225,000 for four years at a public university and $400,000 for four years at a private institution in that year’s dollars. These are the numbers the 529 is engineered to address.

Most families significantly underestimate both the projected cost and the amount they need to save monthly to meet it. A family that wants to fully fund a private-college education for a child born in 2026 — targeting $400,000 in 18 years — needs to contribute approximately $1,050 per month at a 7% average return starting immediately. A family targeting the public university estimate of $225,000 needs approximately $590 per month. These figures assume the full amount is being saved in a tax-advantaged 529, not a taxable account.

The SECURE 2.0 Roth Rollover That Changed the Calculus

The most significant change to 529 plans since their creation is a SECURE 2.0 provision that became fully operational in 2024. It addresses what had been the largest practical objection to aggressive 529 funding: what happens to the money if the beneficiary does not use it all for education?

Under prior law, unused 529 funds withdrawn for non-educational purposes faced a 10% penalty and ordinary income tax on the earnings. That penalty discouraged families from overfunding their plans, creating a tension between saving enough and saving too much.

The new rule allows unused 529 balances to be rolled directly into a Roth IRA for the beneficiary — completely free of the 10% penalty, with the rolled amount treated as a Roth contribution subject to annual Roth IRA contribution limits. The conditions that apply are specific: the 529 account must have been open for at least 15 years, the rollover cannot exceed $35,000 in lifetime total per beneficiary, and annual rollovers cannot exceed that year’s Roth IRA contribution limit — $7,500 in 2026 for individuals under 50.

The practical implication is significant. A family that overfunds a 529 by $35,000 can roll the entire excess into the beneficiary’s Roth IRA over several years — building a tax-free retirement savings foundation for a young adult at the same time the education question resolves. The 529, which was previously a use-it-for-education-or-lose-money-to-the-penalty tool, is now a dual-purpose vehicle: education funding with a Roth IRA safety valve. That change removes the primary reason most financial advisors historically recommended against overfunding 529 accounts.

Pro Tips a Generic Article Would Miss

1. Opening a 529 account today — even with a small initial deposit — starts the 15-year clock required for the SECURE 2.0 Roth rollover, and that clock only runs if the account exists. The 15-year requirement for the 529-to-Roth rollover is measured from the date the account was opened, not the date a large contribution was made. A parent who opens a 529 with $500 today for a newborn and makes their real contributions over the next decade still has a 15-year-old account by the time the child is 15 — fully eligible for the Roth rollover if any balance goes unused. Waiting until a child is five or ten to open the account delays both the investment growth horizon and the 15-year rollover clock simultaneously.

2. The state deduction applies to your state’s own plan — but if your state offers no deduction or a poor investment lineup, the math of using a better out-of-state plan can beat the home-state deduction for high-return investors. Most states require you to use their own plan to claim the state tax deduction. A New York resident who contributes to Virginia’s plan instead receives no New York deduction. But if New York’s plan has high fees or poor investment options relative to a national leader like Utah’s my529 plan, the fee drag over 18 years can exceed the value of the annual deduction. Running both calculations — the fee-adjusted return difference versus the immediate deduction benefit — takes 15 minutes and can be worth thousands over the investment horizon.

3. A 529 can now pay for K-12 tuition, apprenticeship programs, and student loan repayment — provisions that dramatically expanded the definition of qualified expenses and that most families opened their accounts before knowing about. The Tax Cuts and Jobs Act of 2017 allowed 529 funds to pay for up to $10,000 per year in K-12 private school tuition. The SECURE Act of 2019 added apprenticeship programs and up to $10,000 in lifetime student loan repayment for the beneficiary and siblings. These expansions mean that families who aggressively funded a 529 and have a beneficiary who attends public school and receives scholarships can use the balance for K-12 tuition for younger siblings, for loan repayment, for apprenticeship expenses, or ultimately for the Roth rollover — with no penalty in any of those scenarios. The fear of being trapped with unusable money in a 529 is essentially obsolete under the current rules.

FAQ

Q: What is a 529 plan and how does it work? A: A 529 plan is a state-sponsored tax-advantaged savings account designed to pay for education expenses. Contributions are made with after-tax dollars and invested in mutual funds or age-based portfolios. Earnings grow free of federal income tax, and withdrawals for qualified education expenses — tuition, fees, room and board, books, computers — are completely tax-free. Thirty-seven states also provide a state income tax deduction or credit for contributions.

Q: What happens to unused 529 money? A: Unused 529 balances have several penalty-free options under current law. They can be transferred to another qualifying family member’s 529 account with no tax consequences. They can be used for K-12 tuition at private schools, apprenticeship programs, or student loan repayment. And as of 2024, up to $35,000 of unused balances can be rolled into a Roth IRA for the beneficiary over multiple years — provided the account has been open at least 15 years. Withdrawals for non-qualified expenses face a 10% penalty plus ordinary income tax on earnings, but that penalty applies only if none of the above alternatives fit.

Q: How much should I contribute to a 529 plan? A: The target depends on your education cost goal and investment timeline. A family funding a full four-year private university education for a child born today needs roughly $1,050 per month at a 7% average return starting immediately to accumulate $400,000 by 2044. For a four-year public university at $225,000, approximately $590 per month. Contributing the maximum amount your state allows for a deduction each year — typically $5,000 to $10,000 per parent — and investing it in a low-cost age-based portfolio is a reasonable starting framework for most families.

Q: Can I use a 529 for schools in other states? A: Yes. A 529 account opened in any state can be used at any accredited college, university, vocational school, or other eligible educational institution in the United States or abroad. The state where the account is held, the state where the family lives, and the state where the school is located can all be different — none of them need to match.

Q: What is the best 529 plan? A: The best plan for most families depends on whether their home state offers a meaningful tax deduction. If it does, starting with the home-state plan is usually the right choice to capture the immediate deduction. For families in states without a deduction or with high-fee plans — including residents of states with no income tax, who receive no deduction benefit regardless of which plan they use — plans from Utah, Nevada, and New York consistently rank highly for low fees, strong investment options, and flexible account management. The most important factor after tax benefits is the expense ratio of the underlying funds — even a 0.5% annual fee difference compounds significantly over an 18-year horizon.

Every month a 529 account sits unfunded is a month of compound growth that cannot be recovered. The tax-free growth advantage over a taxable account grows larger with every year of investment horizon remaining. For a child born today, starting this month produces approximately $34,000 per $10,000 invested by college age. Starting five years from now produces approximately $24,000 on the same investment. The $10,000 difference is the cost of waiting. The Roth rollover provision means the downside of saving too much has been substantially eliminated. The upside of saving enough — funding four years of college without debt — remains exactly what it was. Open the account. Start the clock. The rest is the same math it has always been.
