529 Plan State Tax Deduction - Restrictions on which state to file?

[nateclevenger]

I live in Kansas and work in Missouri, and contribute to a 529 plan (Kansas plan, although I think that doesn't matter in the context of this question, since both deductions accept out-of-state 529 plans).  I know I can only apply the 529 deduction for one state, but am I required to apply it to the state in which I live (i.e. Kansas), or do I have flexibility to instead apply it to the state I work (which happens to have a larger deduction in this example)?

A. No. Missouri, like most states, limits the deduction to residents.
