Wisconsin tax credits and medical-cost relief

Wisconsin offers tax credits for eligible working families and relief for certain medical costs.

What it is

Wisconsin offers tax credits for eligible working families and relief for certain medical costs.

Wisconsin tax help is not limited to medical bills: working families may qualify for the refundable Earned Income Credit, and some care costs may qualify for a separate child and dependent care credit. Eligible after-tax health premiums and medical expenses may also affect the return. Your social worker can help connect you with a tax preparer who can check the treatment year's rules.

Eligibility rules
  • The documented itemized deduction-credit rules concern the 2025 return filed in 2026. Eligible premiums must be paid after tax and not already excluded or deducted.
What you get
  • A state subtraction for eligible after-tax medical insurance premiums.
  • Eligible medical expenses counted toward the itemized deduction credit.
  • A refundable Earned Income Credit for eligible working families with qualifying children.
  • A review of child and dependent care costs under the tax-year rules.
If you decide to apply
  1. Your social worker can help you decide whether to talk with a tax preparer about Wisconsin credits and medical-cost relief.
  2. Have premium statements showing after-tax payment, itemized bills, receipts and appointment mileage records ready.

Good to know

Premiums already excluded from wages or deducted elsewhere cannot be counted again.

Other details
  • The result depends on your own tax figures. Itemized hospital statements can help establish the expenses.
  • Only medical bills above 7.5% of your income count, and the credit is 5% of what is left, so it is a small amount even in a heavy year. A preparer can check it alongside the earned-income and child-care credits.
  • For tax year 2025, Wisconsin’s Earned Income Credit is 4%, 11% or 34% of the federal credit for one, two, or at least three qualifying children. The highest rounded state maximum is $2,736 for three or more qualifying children. Full-year Wisconsin residency and other tax requirements apply.
  • The ordinary 2025 return filing and payment deadline was April 15, 2026. A qualifying filing extension generally runs to October 15, 2026; it does not extend payment time. A preparer confirms final 2026 rules, exceptions and any disabled-dependent provisions for the treatment year.

Ask your social worker

“Could Wisconsin tax credits or medical-cost relief help us, what rules apply for the treatment year, and could you help us arrange a tax review?”

Why I’m asking: I want to account for eligible costs without counting the same premium twice.

Who does what

The three parts, side by side. The agency decides; nobody on this page does.

You

Keep the receipts from the month of diagnosis and raise both items at filing.

Your social worker

Nothing from the hospital, beyond itemised statements if you ask.

The care team

Records and letters when the application asks for them.

Who decides
The Department of Revenue, through the return.
Ask your social worker
“Can we get itemised statements for the year so we can use them on the state tax return?”

How to apply

First step: Start a folder of premiums and out-of-pocket costs from the month of diagnosis, and raise both items when the return is prepared.

  1. Keep a folder of premiums and out-of-pocket costs from the month of diagnosis.
  2. Raise both items when the return is prepared.

Official application / program page ↗

Where it starts: Keep the year's receipts and raise both items with whoever prepares the return.

What to gather

  • Premium statements showing after-tax payment
  • Itemised medical bills and receipts
  • Mileage to appointments

How long: At filing time for the treatment year.

What a yes looks like

A smaller state tax bill or a larger refund for the treatment year.

What a no looks like, and the next move

Premiums were all pre-tax and the expenses were small. Nothing lost by checking.

Watch out

  • Premiums already taken out before tax cannot be counted again.
  • The rules we could read are for the 2025 return filed in 2026.
  • Keep receipts as you go: reconstructing a year later is where families give up.

The numbers and the rules

The arcane layer, kept on purpose. Checked September 11, 2026.

What it is worth

Tax-year-specific review of Wisconsin earned-income and child/dependent-care credits, eligible after-tax insurance subtraction and itemized deduction credit. For tax year 2025, the itemized credit is 5% of Schedule 1 excess; the medical component first uses the 7.5% AGI floor.

Legal protection: A subtraction for medical care insurance premiums paid with after-tax money · Medical expenses can count towards the itemised deduction credit

What it costs the family: None.

The eligibility facts, as published

Premiums
amounts paid with after-tax contributions, not those already excluded or deducted
Expenses
medical expenses in the itemised deduction credit on the 2025 return
Unknowns
2026 tax-year rules and any dedicated disabled-dependant relief

The trap: Premiums already taken out before tax cannot be counted again. Keep the year's receipts as you go, because reconstructing them later is the part families give up on.
