Missouri 529 Tax Deduction 2026: up to $16,000 a year, worth about $752
Missouri takes money off your state tax bill when you put money into a 529 college fund for your child. Most parents never claim it — not because it's hard, but because nobody told them. Here's the whole thing in plain English.
What you can deduct
$8,000 ($16,000 married filing jointly) per year, per taxpayer. Fine print: per taxpayer; any state’s plan (bills to end that died in 2025 and 2026).
What it's worth
About 4.7 cents per dollar you contribute, up to the limit.
| You put in | Off your Missouri tax bill (≈) |
|---|---|
| $1,000 | $47 |
| $2,500 | $118 |
| $8,000 | $376 |
| $16,000 | $752 |
The trick: you don't need new money
If you pay for daycare, you probably qualify for federal tax breaks worth $1,000–$3,000 a year — the Dependent Care FSA at work and the childcare credit at tax time. Route that money into the 529 and Missouri pays you again for saving it. Same dollars, three tax breaks.
