Missouri 529 Plan And College Savings Options
Missouri's 529 plan is MOST 529, a low-cost direct-sold plan, and it's a sound default for Missouri families who want a simple Vanguard age-based account. The Missouri deduction of up to $8,000 per taxpayer ($16,000 joint) works with any state's 529 plan, so the deduction alone doesn't lock you into MOST. Watch three Missouri-specific traps: recapture on a non-qualified withdrawal lands on the account owner even for money a grandparent deducted, Missouri hasn't ruled on 529-to-Roth IRA rollovers, and credential program costs outside an eligible school get recaptured. If you're new to these accounts, start with how 529 plans work.
Missouri 529 Plans At A Glance
| Plan | Type | Annual Cost | Who It's For | Status |
|---|---|---|---|---|
| MOST—Missouri's 529 Education Plan (MOST 529) | Direct-sold savings plan | 0.16%–0.17% on age-based portfolios; 0.16%–0.41% on individual portfolios | Families who open and manage the account themselves | Open |
| MOST 529 Advisor Plan | Former advisor-sold plan | Accounts moved into the direct plan in 2016 | Former advisor-plan owners | Merged |
Missouri 529 Tax Deduction And Tax Rules
Missouri lets each taxpayer subtract up to $8,000 a year in 529 contributions, or $16,000 for married couples filing jointly, and the subtraction covers MOST 529 and any other state's 529 plan (RSMo 166.435). The deduction goes to the person who contributes, and the Department of Revenue accepts bank statements or canceled checks in the contributor's name as proof, so a grandparent who files a Missouri return can claim it (Missouri Department of Revenue). Our state-by-state 529 tax deduction table shows how that compares with neighboring states.
Contributions count for the year they're made, so mailed checks must be postmarked by December 31, and money rolled in from another state's 529 plan doesn't qualify for the deduction (MOST 529 Program Description). You claim the subtraction on Form MO-A, Part 1, line 12, and report any non-qualified distribution as an addition on line 3 (Missouri Department of Revenue), and our list of qualified 529 plan expenses covers what counts.
| Situation | Missouri Tax Treatment |
|---|---|
| Contribution to MOST 529 | Deductible up to $8,000 per taxpayer, $16,000 for joint filers |
| Contribution to another state's 529 plan | Deductible under the same limit; Missouri has tax parity |
| Qualified college withdrawal (any accredited school, in or out of state) | Tax-free, including withdrawals from other states' 529 plans |
| K-12 tuition and expenses | Tax-free up to $20,000 per beneficiary per year starting in 2026; the plan says Missouri treats these as qualified withdrawals |
| Student loan repayment | Tax-free up to $10,000 lifetime per borrower |
| Registered apprenticeship costs | Tax-free |
| Non-qualified withdrawal | Previously deducted contributions and earnings added back to Missouri income |
| Contribute and withdraw right away (529 churning) | Allowed; no holding period, so the deduction applies even if the money pays a qualified expense soon after |
| Rollover from MOST 529 to another state's plan | Not taxable and not recaptured |
| Rollover from another state's plan into MOST 529 | Tax-free, but not eligible for the Missouri deduction |
| 529-to-Roth IRA rollover | Unresolved; the Missouri Department of Revenue hasn't said whether it triggers recapture |
Missouri's statute adds back money "not held for the minimum length of time established by the appropriate Missouri board," but the board's rule sets that minimum as whatever federal section 529 requires, "if at all" (15 CSR 50-4.020), and federal law sets none. The MOST 529 Program Description repeats that the board minimum applies "if at all" and adds no holding period, and a contribution is available to withdraw after seven business days (MOST 529). That means Missouri families paying tuition out of pocket can route up to $8,000 ($16,000 joint) through a 529 first and still claim the deduction, a move states like Wisconsin and Montana have blocked, as our breakdown of 529 plan churning and withdrawal limits explains.
The Roth rule is still open in Missouri. Federal law lets a 529 that's been open at least 15 years roll up to $35,000 into the beneficiary's Roth IRA, but MOST 529 says the Missouri Department of Revenue hasn't issued guidance on whether that rollover will be recaptured (MOST 529 Program Description), and the statute only exempts qualified expenses and 529-to-529 rollovers from the add-back (RSMo 166.435). Read our 529-to-Roth IRA rollover rules and ask a Missouri tax preparer before you move money that was deducted.
Missouri defines qualified expenses by reference to federal section 529 "as amended" (RSMo 166.410), and the plan says K-12, apprenticeship, and student loan withdrawals are qualified for Missouri tax purposes (MOST 529 Program Description). The exception is the new federal category for postsecondary credential programs: a withdrawal for a credential expense that isn't tied to attendance at an eligible educational institution is taxed in Missouri, including recapture of the deduction. Our breakdown of the 2026 529 plan expansion covers what changed federally.
How Missouri's 529 Plan Ranks
Missouri ranks 23rd of the 50 state plans in our best 529 plans rankings, which include Washington, D.C., with a 64.4% net return on investment. Our Net ROI score models $100 a month for 10 years at a 5% annual return, subtracts plan fees, and reinvests the value of the state tax break each year. MOST 529 lands in the middle of the pack because its 15 basis point fee is higher than the cheapest plans, while its 4.7% tax break is what carries the score.
| State | Fees (Basis Points) | State Tax Break | Net ROI |
|---|---|---|---|
| Indiana (#1 overall) | 12.5 | 20% | 87.8% |
| Kansas | 2 | 5.6% | 67.8% |
| Illinois | 8.25 | 5% | 65.9% |
| Oklahoma | 10 | 4.5% | 64.8% |
| Missouri (#23) | 15 | 4.7% | 64.4% |
| Nebraska | 14 | 4.6% | 64.4% |
| Iowa | 14 | 3.8% | 63.2% |
| Arkansas | 48 | 3.7% | 57.8% |
| Tennessee | 20 | 0% | 56.5% |
| Kentucky | 35 | 0% | 54.3% |
Missouri is a tax-parity state, so a resident can put money in another state's plan and still take the Missouri deduction (RSMo 166.435). That doesn't make this table a shopping list, because each score assumes a taxpayer in that state using its own plan, but it does mean a Missouri family can compare fees across states without losing the tax break. Kansas's plan shows up at 2 basis points in our table, and the full rankings table lists all 50 state plans.
The gap with the top of the list comes down to two levers Missouri controls. Indiana's 20% tax credit is what puts it at #1, and Missouri's 4.7% break and 15 basis point fee keep it in the middle, so a larger deduction or lower fees would move Missouri families up. If that matters to you, share these numbers with your state legislators, and use our 529 plan tax deductions by state table to show how other states reward savers.
Should Missouri Residents Use MOST 529?
Yes, for most Missouri families who want a simple, low-cost account. MOST 529's age-based options cost 0.16% to 0.17% a year all-in with no account fees or sales charges (MOST 529 Program Description), and Missouri lets you deposit your state tax refund straight into a MOST account. Because the deduction follows you to any state's plan, families who care most about fees can check our best 529 plans list before they open an account.
Families who already hold another state's plan don't need to move it, since the Missouri deduction applies to new contributions there too, and a rollover into MOST 529 isn't deductible anyway. Nonresidents can open MOST 529 as well, since the plan has no residency or income requirement (MOST 529), but they should first check where to open a 529 plan in their own state.
Four years at an in-state Missouri public university runs about $98,400 on campus, so the average MOST 529 balance of about $26,500 covers a little more than one year. Our Missouri college costs and financial aid breakdown lists costs by school, and our 529 savings benchmarks by age show what to aim for.
Missouri 529 Plan Details
MOST 529 is administered by the Missouri Education Program Board, chaired by the State Treasurer, with Ascensus as program manager and Vanguard as investment manager (MOST 529 Program Description). As of June 30, 2026, MOST 529 held $5.47 billion across 206,299 open accounts, and Missouri ranked 28th among the states in 529 assets (The 529 Network). Missouri residents own about 90% of MOST accounts (Missouri Education Program Board 2024 annual report), and our 529 plan and college savings statistics show how that compares nationally.
| Missouri Plan (June 30, 2026) | Open Accounts | Assets | Average Balance |
|---|---|---|---|
| MOST—Missouri's 529 Education Plan | 206,299 | $5.47 billion | $26,525 |

Total annual cost runs 0.16% to 0.17% on the Vanguard portfolios used in the age-based options, including a 0.14% plan management fee and no state fee, and up to 0.41% on the DFA individual portfolios (MOST 529 Program Description). On a $26,525 balance, the plan's average as of June 30, 2026, that's about $42 to $45 a year in an age-based option, which our 529 balance by age benchmarks can put in context.

The Vanguard Interest Accumulation Portfolio lists 0.16%, but the plan notes external costs of 0.15% to 0.20% that reduce its return and aren't in that figure (MOST 529 Program Description). Missouri's advisor-sold plan closed under the 2016 program contract, and its owners were moved into the direct plan (Missouri Education Program Board 2024 annual report), so families who want help can compare the brokers in our list of the best brokers to open a 529 plan.
MOST 529 Changes Under Review
MOST 529's program management contract with Ascensus was extended in June 2020 to run to June 2026, and the Treasurer's office said it planned to issue a request for proposals for program management in the fourth quarter of 2025 (Missouri Education Program Board 2024 annual report). The board hasn't published the outcome, and the plan's website still names Ascensus and Vanguard as of September 2026. We'll update this page if the manager or fees change, and our 529 plan rollovers and transfers explainer covers your options if they do.
- ◆The 2024 board report lists the Ascensus contract term as running to June 2026
- ◆The board's November 19, 2025 agenda included a closed session on procurement updates (Missouri State Treasurer)
- ◆The board held a special meeting on September 16, 2026 that consisted of a closed session (Missouri State Treasurer)
- ◆The March 2026 plan supplement, the latest fee schedule, still lists a 0.14% plan management fee
Other Missouri College Savings Programs
Upromise. Upromise lets you earn money for your MOST 529 account through rebates and rewards on everyday spending, and the Upromise credit card sends cash back straight into your child's 529 plan (Upromise). You can link a MOST 529 account to your Upromise profile, so the rewards stack on top of Missouri's state tax deduction.
Tax refund deposit. Missouri filers can send all or part of their state income tax refund straight into a MOST 529 account, with a $25 minimum, by completing Form 5632 with their return (Missouri Department of Revenue). It's an easy way to add to the account each spring, and our 529 plan contribution limits page covers how much you can put in.
MO ABLE. Missouri residents whose disability began before age 46 can save in a STABLE account through MO ABLE, run by the State Treasurer's office, with up to $20,000 a year in contributions and more for employed account holders (MO ABLE). Balances under $100,000 don't affect SSI, and MO ABLE contributions may qualify for a Missouri deduction, which our 529 plan overview compares with regular college savings.
Leftover money. Families with money left after college can change the beneficiary to a sibling, pay down up to $10,000 of student loans, or roll to a Roth IRA, keeping Missouri's open question on Roth recapture in mind. Our list of what to do with leftover 529 money covers each option, and Missouri graduates in teaching or health care should also check Missouri student loan forgiveness programs.
Frequently Asked Questions
What Is The Missouri 529 Plan Called?
Missouri's 529 plan is MOST—Missouri's 529 Education Plan, known as MOST 529, a direct-sold plan managed by Ascensus with Vanguard and DFA portfolios. The state's advisor-sold version closed in 2016, and our 529 plans by state hub lists every state's plans.
Is The Missouri 529 Plan Tax Deductible?
Yes. Missouri taxpayers can deduct up to $8,000 a year, or $16,000 for joint filers, and contributions to any state's 529 plan qualify (Missouri Department of Revenue). Our state 529 tax deduction table shows how that compares state by state.
Can Grandparents Get The Missouri 529 Deduction?
Yes, if they file a Missouri return and contribute. The deduction goes to the contributor, and the Department of Revenue accepts documents showing the contribution in the claimant's name (Missouri Department of Revenue). If the money later comes out for a non-qualified use, the plan says the add-back falls on the account owner, which our breakdown of how 529 plans work can help families plan around.
Can I Use A Missouri 529 Plan At An Out-Of-State College?
Yes. Missouri doesn't tax qualified withdrawals, and qualified expenses follow the federal definition, which covers eligible schools in any state and abroad (MOST 529). The list of qualified 529 plan expenses is the same no matter where the school is.
Can I Contribute To A Missouri 529 Plan And Withdraw Right Away?
Yes. The board's minimum holding period is whatever federal law requires, and federal law requires none, so you can deduct a contribution and use it for a qualified expense once it clears (15 CSR 50-4.020). Match the withdrawal to an expense paid in the same calendar year, and see which states restrict this in our 529 plan churning breakdown.
What Happens If I Withdraw Missouri 529 Money For Non-Qualified Expenses?
Missouri adds back contributions that were previously deducted plus the earnings on the withdrawal (Missouri Department of Revenue). The earnings also face federal income tax and the 10% federal penalty, which our explainer on the 529 plan penalty shows how to avoid.
Can I Use My Missouri 529 Plan For Private K-12 School?
Yes. Starting in 2026, you can withdraw up to $20,000 per beneficiary per year for K-12 tuition and related expenses, and MOST 529 says these withdrawals are qualified for Missouri tax purposes (MOST 529 Program Description). Our walkthrough on using a 529 plan for private school covers the paperwork.
