Education Benefits
What a 529 is, the 2026 rules that made it far more flexible, and how it pairs with a transferred GI Bill so you don't double-fund the same tuition.

A 529 plan is a tax-advantaged college savings plan, named for Section 529 of the tax code and sponsored by states, state agencies, or schools. There are two kinds: an education savings plan, where you invest and the balance grows, and a prepaid tuition plan, where you lock in tuition at today's rates.
The tax deal is straightforward. There is no federal deduction for putting money in, but earnings grow tax-deferred, meaning you owe no tax on the growth until you take it out, and qualified withdrawals come out federal-income-tax-free. Many states add their own deduction or credit for contributions, so your state plan can carry an extra perk.
There is no annual federal contribution limit, though each state sets a total account maximum. Contributions count as gifts for tax purposes, and a special election lets you front-load several years of gifts at once. Those gift figures change yearly, so confirm the current numbers with the IRS or a tax advisor before a big deposit.
A 529 is flexible money you set aside for a future student. There is no federal break going in, but the growth and qualified withdrawals are where it pays off, and the 2026 rules cover far more than tuition.

More than it used to. For 2026, the federal list covers college tuition, fees, books, and room and board, K-12 tuition up to $20,000 per student a year, registered apprenticeships and many credentialing programs, and up to $10,000 of student loans. Transportation, healthcare, and extracurriculars do not qualify. State tax treatment of some of these uses varies, so your state may not match every line.
For most military families, the answer is both, used for different jobs. A transferred Post-9/11 GI Bill covers tuition (to the caps), housing, and books for one child, up to 36 months. A 529 is flexible money you control, and it does the things the GI Bill cannot.
Where a 529 earns its keep: tuition above the private-school cap, a second or third kid the GI Bill does not stretch to, graduate school after the GI Bill entitlement runs out, K-12, or a trade program. Think of the GI Bill as the primary and the 529 as the gap-filler, plus the backup plan if a kid changes course.
The one rule to respect is no double-dipping the tax break. You cannot take a tax-free 529 withdrawal for the same expense that a tax-free GI Bill benefit already paid. VA education benefits are tax-free and reduce the expenses you can match with a 529, so coordinate the two and keep your receipts.
A transferred GI Bill and a 529 do different jobs. Run the GI Bill as the primary and lean on the 529 for everything it cannot reach. If the GI Bill ends up covering it all, the 529 still has clean exits.
The pairing: Use the GI Bill as the primary (one kid: tuition, housing, books) and a 529 as the gap-filler: extra kids, grad school, K-12, or costs above the cap.

Good problem. You have several clean exits, and none of them forfeit the account. You can change the beneficiary, meaning the future student the account is for, to another child or eligible family member and use it for their school. You can use it for other qualified costs, such as graduate school, a credential program, or up to $10,000 of student loans. You can roll up to $35,000 into the beneficiary's Roth IRA, a retirement account funded with after-tax money, if the account has been open long enough. Or you can take a withdrawal up to the GI Bill amount and skip the 10% penalty.
That last one is the military-specific trick. Because the GI Bill is tax-free educational assistance, the tax code waives the usual 10% additional tax on a 529 withdrawal up to that amount. You still owe regular income tax on the earnings portion, but not the penalty. A fully GI-Bill-funded degree does not trap your 529 savings.
Under the SECURE 2.0 law, in effect since 2024, unused 529 money can move into the beneficiary's Roth IRA, with guardrails. The lifetime cap is $35,000 per beneficiary. The 529 account has to have been open for at least 15 years. Money and its earnings added in the last 5 years are not eligible to roll. And each year's rollover counts against the beneficiary's annual Roth contribution limit and is reduced by any other IRA contributions they make that year.
The rules are detailed and a misstep is taxable, so confirm the current annual Roth limit and these conditions with a tax advisor before acting.
What is a 529 plan?
A tax-advantaged college savings plan under Section 529 of the tax code. Earnings grow tax-deferred and qualified withdrawals are federal-income-tax-free. There are two types: education savings plans and prepaid tuition plans.
Should I use a 529 or the GI Bill?
Both, for different jobs. The GI Bill covers tuition, housing, and books for one student up to its caps. A 529 fills gaps the GI Bill does not: extra kids, grad school, K-12, and costs above the cap.
Can I use a 529 and the GI Bill for the same kid?
Yes, but not for the same expense tax-free. Coordinate them so the tax-free GI Bill and the tax-free 529 withdrawal are not both claimed on the identical charge.
What happens to a 529 if my kid's college is fully covered by the GI Bill?
You can change the beneficiary, use it for other qualified costs, roll up to $35,000 to the beneficiary's Roth IRA, or withdraw an amount equal to the GI Bill benefit without the 10% penalty. Income tax on the earnings still applies.
Can a 529 pay for K-12 or trade school?
Yes. K-12 costs qualify up to $20,000 per student a year starting in 2026, and registered apprenticeships and many credentialing programs qualify too.
Can I move 529 money into a Roth IRA?
Yes, up to $35,000 over the beneficiary's lifetime, if the 529 has been open at least 15 years and other conditions are met. It rolls to the beneficiary's Roth, not yours.
