529 contributions in South Dakota

Varies

Are 529 Contributions Tax Deductible in South Dakota?

Short answer: No: South Dakota has no state income tax, so there's nothing to deduct 529 contributions from. No personal income tax, so no state deduction; South Dakota sponsors the CollegeAccess 529 plan.

There's no federal deduction for 529 contributions; growth is tax-free when used for qualified education costs. You can still use any state's plan.

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.
