529 contributions in Missouri

Varies

Are 529 Contributions Tax Deductible in Missouri?

Short answer: Yes on your Missouri return: $8,000 single / $16,000 joint per taxpayer. Contributions to any state's 529 plan count. Tax parity state; rollovers not deductible. A 2026 bill (HB 2116) limiting the deduction to MOST from 2027 stalled in committee.

There's no federal deduction for 529 contributions; growth is tax-free when used for qualified education costs.

Records to keep: Keep receipts, statements, and a note of what each cost was for. Compare itemizing to the 2026 standard deduction ($16,100 single / $32,200 joint) before you claim.
