Wisconsin 529 Tax Deduction And Tax Rules

For the 2026 tax year, Wisconsin taxpayers can deduct up to $5,280 per beneficiary for contributions to an Edvest account, whether they file single or jointly, or $2,640 per beneficiary for each spouse filing separately (Edvest). The deduction is open to any Wisconsin taxpayer who contributes, not just the account owner, and contributions above the yearly limit carry forward to future years. Our state-by-state 529 tax deduction table shows how that compares with neighboring states.

The limit is per beneficiary, so a parent with three children can deduct up to $15,840 in 2026, and a grandparent can claim a separate deduction for the same grandchild. Growth is tax-deferred and qualified withdrawals are tax-free, including withdrawals for an out-of-state college, which our list of qualified 529 plan expenses breaks down. Non-qualified withdrawals and rollovers to another state's 529 plan are added back to Wisconsin taxable income to the extent they were previously deducted (Savingforcollege).

Wisconsin is one of the few states that shuts down 529 churning. Edvest uses first-in, first-out accounting, and any withdrawal taken within 365 days of when the money was contributed, or carried forward, must be added back to your Wisconsin taxable income (Edvest). The add-back applies to the extent the contribution was deducted and the account balance before the contribution was less than the withdrawal (Savingforcollege). Plan tuition contributions at least a year ahead of the bill, and see how Wisconsin's rule compares with Michigan's, Montana's, and Utah's in our breakdown of 529 plan churning and withdrawal limits.

Wisconsin treats 529-to-Roth IRA rollovers the way federal law does: an account open at least 15 years can move up to $35,000 to the beneficiary's Roth IRA without federal or Wisconsin income tax or penalties, as long as the rolled money has been in the account at least five years (Edvest). Read our 529-to-Roth IRA rollover rules before you move leftover money.

Edvest says K-12 withdrawals up to $20,000 per student per year are free of Wisconsin tax (Edvest), but we couldn't confirm how the Wisconsin Department of Revenue treats the new federal category for postsecondary credential programs. Check with the department before relying on that use for state purposes, and see our breakdown of the 2026 529 plan expansion for what changed federally.

How Wisconsin's 529 Plan Ranks

Wisconsin ranks 7th of the 50 state plans in our best 529 plans rankings, which include Washington, D.C., with a 70.6% net return on investment. Our Net ROI score models $100 a month for 10 years at a 5% annual return, subtracts plan fees, and reinvests the value of the state tax break each year. Edvest lands near the top because its fees are among the lowest in the country and its 7.7% tax break is above the national middle.

Don't read this table as a reason to switch plans. Each state's score assumes a taxpayer in that state using its own plan, so a Wisconsin resident who moves to Minnesota's plan gives up the Wisconsin deduction and gets no Minnesota break in return. The ranking shows what a dollar is worth inside Edvest compared with what families in other states get, and the full rankings table lists all 50 state plans.

The gap with the top of the list comes down to two levers Wisconsin controls. Indiana's 20% credit is what puts it at #1, and Edvest's fees are already near the floor, so the size of the deduction is the lever left to pull. If that matters to you, share these numbers with your state legislators, and use our 529 plan tax deductions by state table to show how other states reward savers.

Should Wisconsin Residents Use Edvest?

Yes, for nearly every Wisconsin taxpayer who manages their own account. Edvest averages 0.13% a year in fees with no sales charges or account fees (Edvest), and a resident who picks another state's plan gives up a deduction worth up to $5,280 per beneficiary. Our 529 plan tax deductions by state table shows how Wisconsin's break compares.

Families who already hold another state's plan can roll the principal into Edvest and deduct it, subject to the yearly limit (Edvest), and our explainer on 529 plan rollovers and transfers covers the once-per-year federal limit. Nonresidents can open Edvest too, since anyone 18 or older with a Social Security number or tax ID can open an account, but they should first check where to open a 529 plan in their own state.

Four years at an in-state Wisconsin public university runs about $98,000 on campus, so the average Edvest balance of about $27,700 covers a little more than one year. Our Wisconsin college costs and financial aid breakdown lists tuition by school, and our 529 savings benchmarks by age show what to aim for.

Wisconsin 529 Plan Details

Edvest is managed by TIAA-CREF Tuition Financing on behalf of the State of Wisconsin (Edvest). As of June 30, 2026, Wisconsin's two plans held $9.97 billion across 369,836 open accounts, which ranked Wisconsin 18th among the states in 529 assets (The 529 Network). Our 529 plan and college savings statistics show how that compares nationally.

Other Wisconsin College Savings Programs

Upromise. Upromise lets you earn money for your Edvest account through rebates and rewards on everyday spending, and the Upromise credit card sends cash back straight into your child's 529 plan (Upromise). You can link an Edvest account to your Upromise profile, so the rewards stack on top of Wisconsin's state tax deduction.

Leftover money. Families with money left after college can change the beneficiary to a sibling, pay down up to $10,000 of student loans, or roll to a Roth IRA without Wisconsin tax if the federal conditions are met. Our list of what to do with leftover 529 money covers each option, and Wisconsin graduates should also check Wisconsin student loan repayment assistance programs.
