Wisconsin 529 plans

State tax deduction or credit

Contributions to a Wisconsin 529 plan of up to $5,130 per beneficiary by an individual or married couple filing jointly, and up to $2,560 per year by married couple filing separately, are deductible in computing Wisconsin taxable income. The deduction is available to any Wisconsin taxpayer who contributes to an account in the plan, not just the account owner. Contributions exceeding the maximum deduction amount for the tax year may be carried forward to future tax years. Rollover contributions of the principal amount from another state's 529 plan are eligible for the Wisconsin income tax deduction subject to applicable yearly limitations. Wisconsin employers, including a sole proprietor, making contributions to an employee’s Account may claim a tax credit of up to 50% of the amount the employer contributes, not exceeding a maximum credit of $820, per employee, for the 2025 tax year.
