529 contributions in Wisconsin

Varies

Are 529 Contributions Tax Deductible in Wisconsin?

Short answer: Yes on your Wisconsin return: $5,280 per beneficiary (single or joint); $2,640 MFS. Only contributions to the state's own plan count. Edvest/Tomorrow's Scholar only; any WI contributor qualifies; contributions through April 15 count for prior year; indexed annually.

Carryforward: Yes (excess carried forward). 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.
