Missouri 529 Tax Deduction

Missouri offers a valuable tax incentive for residents who save for education through a 529 college savings plan.

The Missouri 529 Tax Deduction allows eligible taxpayers to reduce their Missouri taxable income by contributing to a MOST 529 plan or to any other state’s 529 plan, thanks to Missouri’s 529 tax parity.

This makes the benefit flexible and widely accessible, regardless of which state’s plan you choose. Often described as a “win-win-win,” this benefit combines tax-deferred growth, tax-free withdrawals for qualified education expenses, and an immediate Missouri state income tax deduction.

Key Features of the Missouri 529 Tax Deduction

Deduction Amount

• Up to $8,000 per year for single filers.
