Most conversations about college savings start and end with one question: are you saving enough?
But the question goes beyond this. What we really want to do is fund education expenses in the most efficient manner possible, with the most control and flexibility possible.
A 529 is one of, if not the most, prominent college savings vehicles out there. Most people contribute for years without ever fully understanding what it can and can't do.
And rarely does someone stop to ask another question. What happens if in the end you have enough for education and the account still has money left in it?
The Real Value of a 529
Money inside a 529 grows tax-deferred, and withdrawals come out completely tax-free when used for qualified expenses. This is what makes it a great vehicle for education focused savers.
While there is no federal deduction for contributions, there may be a state income tax deduction for contributions. In Missouri, single filers can deduct up to $8,000, married couples filing jointly up to $16,000. Unlike most states, Missouri's deduction applies even when contributing to another state's 529 plan, not just its own.
Most plans also keep the investing side simple. Age-based portfolios automatically shift from growth to conservative as the beneficiary gets closer to needing the money, similar to a target-date fund. For those who want more control, static portfolios let you choose and hold a fixed risk profile the whole way through. Either way, the options tend to be low-cost and built for long-term growth. You do lack the ability to have a more active management approach.
How and Who Can Fund a 529 Account
🔹Regular or automatic contributions - anyone can contribute, on any schedule. Missouri's plan caps out around $550,000 total per beneficiary, in line with most states nationally.
🔹Gifts from family - grandparents, aunts, uncles, or anyone else can contribute directly, often through a simple online gifting link. All contributions to a beneficiary count together against that year's $19,000 gift tax exclusion per giver.
🔹Super funding - instead of gifting up to the annual exclusion each year, the IRS allows front-loading five years of gifts into a single contribution without triggering gift tax. At 2026's $19,000 exclusion, that's $95,000 in one contribution for an individual, or $190,000 for a married couple, filed on Form 709 and spread over five years.
What Counts as a Qualified Use of Funds
A 529 isn't just a college fund anymore.
🔹Higher education - tuition, fees, room and board, books, and required supplies at any college, university, or graduate program that participates in federal student aid.
🔹Trade and vocational schools - culinary school, technical training, apprenticeship programs. If the institution qualifies for federal student aid, the expenses usually qualify too.
🔹K-12 tuition - public, private, and religious schools now qualify for up to $20,000 per student per year as of 2026, double the old $10,000 limit.
🔹Technology - computers, required software, and in some cases internet service, as long as the student primarily uses it and the school requires it.
🔹Room and board - on-campus housing counts. Off-campus housing counts too, up to the same cost as campus housing.
🔹Roth IRA rollovers - unused funds can actually roll into a Roth IRA for the beneficiary under certain conditions. It's widely unknown and misunderstood. More details on that below.
What Catches People Off Guard
The rules aren't always intuitive.
🔸Timing matters - withdrawals need to happen in the same calendar year as the expense. Pull the money out in December for a spring semester bill, and you may have a non-qualified withdrawal on your hands. If a class gets dropped or a refund comes back, you generally have 60 days to redeposit it into the 529 without penalty.
🔸Not everything school-related qualifies - transportation to campus, most extracurriculars, and general living expenses beyond room and board typically don't count.
🔸State rules can differ from federal rules - some states don't fully conform to the newer K-12 and expanded expense rules. Check your specific state before assuming a withdrawal is qualified on a state level as well.
What to Do if There Is Money Left Over
Situations change and college funding adds other variables. Scholarships, decisions to go in a more cost-effective program, a new career path, or perhaps just better than expected market conditions can all result in having more funds than planned for the ultimate purpose.
Fortunately you have three real options to consider.
🔹Change your beneficiary - you can change the beneficiary to another qualifying family member, a sibling, a cousin, even yourself, without any penalty.
🔹Roll it into a Roth IRA - thanks to SECURE 2.0, unused 529 funds can move directly into a Roth IRA owned by the beneficiary, but there are a few nuances to understand.
- The lifetime cap is $35,000.
- The 529 has to be at least 15 years old.
- Annual rollovers can't exceed that year's Roth contribution limit, $7,500 in 2026.
- Only contributions made at least 5 years before the transfer qualify.
- The beneficiary must have earned income to contribute. Unlike regular Roth contributions, there are no income limits, meaning higher-earning beneficiaries who'd otherwise be locked out of Roth contributions entirely can still contribute up to the annual maximum.
🔹Take it back - as the account owner, you can withdraw the money for any reason, at any time. You still have control. The catch is the earnings portion gets hit with ordinary income tax plus a 10 percent penalty. It's the least efficient of the three options, but it's good to know it exists.
You don't have to decide today. Doing nothing means the account continues to grow. There's no penalty for letting the money sit, and no deadline to spend it. But rarely does a "do nothing" approach add long-term value on its own. Staying put strategically, while you work through one of the three approaches above, is what turns inaction into intention.
Final Thoughts
A 529 can feel like a simple trade off. Money goes in, tuition comes out. But the balance between contributing too much or over funding can leave a lot to question.
The account funds more than a four-year degree, comes with real tax advantages, and gives you more than one good option if the balance outlives the need. New rules and more advanced strategies can make this a more interesting conversation.
Back to school season has a way of putting education expenses on everyone's mind. Tuition bills, dorm shopping, tax-free school supply shopping, it's a lot to think about. And a good moment to step back and make sure the purpose behind it all is actually working toward your intentions.
If your family has a 529 that could use a second look, whether it's fully funded, underfunded, or sitting with more in it than you'll need, give us a call.
