Updated October 5, 2026. Quick answer: No, with one difference in the penalty. The Department of Revenue’s Fact Sheet 1105 says “Wisconsin follows the provisions of Public Law 108-173” relating to health savings accounts for 2011 and after, and that “The federal provisions relating to HSAs generally apply for Wisconsin”. The 2026 federal HSA limits are $4,400 for self-only coverage and $8,750 for family coverage.

What the Wisconsin documents say
Revenue Fact Sheet 1105, Health Savings Accounts, was last updated on February 23, 2026 and carries the 2026 federal limits. Its section on Wisconsin treatment says “The federal provisions relating to HSAs generally apply for Wisconsin” for 2011 and thereafter, and then names the one difference: “The only difference is the imposition of penalties”.
The statutes the fact sheet cites are “secs. 71.01(6) and 71.98(1), Wis. Stats., and sec. 223, IRC”. Section 223 is the federal HSA section.
Earnings, distributions and the rest
On earnings, the fact sheet’s description of the federal treatment says “Earnings on the account are generally not taxable to the individual”, and says Wisconsin applies the federal provisions. On distributions it says “Distributions from the HSA are tax-free if used for qualified medical expenses” and that a distribution not used for them must be included in income.
The Wisconsin penalty for excess contributions that are not withdrawn and for distributions not used for qualified medical expenses is “33 percent of the federal penalty”. A Schedule I adjustment is available only to someone who had a federal HSA before 2011, was not allowed a Wisconsin deduction for it, and had a balance on December 31, 2010.
A worked example at the 2026 family limit
An illustration, not a return: a Wisconsin resident with family coverage who puts the 2026 federal family limit of $8,750 into an HSA gets the same deduction or payroll exclusion on the Wisconsin return as on the federal one, because the fact sheet says the federal provisions apply. That is $4,350 more than the self-only limit of $4,400 would allow. A contribution above the limit that is not withdrawn draws the Wisconsin penalty described above.
What a mover should know
Every figure on this page is Wisconsin’s own rule. If you moved during the year, or live in one state and work in another, check each state’s page and return, because the documents read here describe only Wisconsin and none of them settles a part-year or two-state case. The federal side is the same everywhere: see CMG’s 2026 HSA contribution limits page, and state tax on HSA contributions for the other states checked.
What the documents do not say
- The fact sheet does not give a Wisconsin tax rate or a bracket, and this page states none. It describes the federal penalty only in general terms, and this page does not compute a Wisconsin penalty amount from it.
Common mistakes
- Assuming the Wisconsin penalty equals the federal one; the fact sheet says it is 33 percent of the federal penalty.
- Filing a Schedule I adjustment when there is no pre-2011 HSA balance; the fact sheet limits it to that case.
- Assuming the answer for one state applies to another, or that the state answer changes the federal limits.
