Wisconsin Retirement Income Subtraction (2026): Who Qualifies + How to Avoid Missing It

If you’re retired—or about to retire—in Wisconsin, there’s a new tax rule that can save you thousands of dollars per year.

It’s called the Wisconsin Retirement Income Subtraction.

And on the surface, it sounds simple:

• Up to $24,000 per person
• Or $48,000 for married couples
• Tax-free at the state level

But here’s what many people don’t realize:

• It’s not automatic
• It can be accidentally missed
• And one small decision can wipe it out completely

After reviewing dozens of Wisconsin retiree tax returns, I’ve seen this happen more often than you’d expect.

Let’s walk through how it works—and how to make sure you don’t leave money on the table.

What Is the Wisconsin Retirement Income Subtraction?

If you’re 67 or older, Wisconsin allows you to subtract retirement income from your state taxes.

Here’s the simple version:

• Age requirement: 67+ by December 31
• Maximum subtraction:
  • $24,000 (single)
  • $48,000 (married filing jointly)
• Applies to taxable retirement income

That includes:

• IRA withdrawals
• 401(k) withdrawals
• Pension income

And remember:
Social Security is already tax-free in Wisconsin.

If you qualify, this is one of the largest tax breaks available to retirees in Wisconsin.

What Income Qualifies for the Wisconsin Retirement Income Subtraction?

This deduction applies to retirement income that is:

• From a qualified retirement plan like a pension or Traditional 401(k) or IRA
• Taxable at the federal level
• Not already excluded elsewhere on your Wisconsin return

In plain English:
If it’s taxable retirement income, and you’re 67+… it may count.

Why So Many Retirees Miss This Deduction

I’ve reviewed dozens of Wisconsin retirees’ income tax return and I found that:
Roughly 20% of Wisconsin retirees appear to be missing the Wisconsin Retirement Income Subtraction.

And it usually comes down to one of two things:

1. They accidentally choose credits instead

If you take this subtraction…You cannot claim certain tax credits

Including:

• School Property Tax Credit
• Itemized Deduction Credit
• Credits on Schedule CR
• Any carried-forward credits

So what happens?

People (or their tax preparer):

• Keep the familiar $300 credit
• And accidentally give up a potentially $1,000+ benefit

---

2. The subtraction never gets applied just because of a missed checkbox

In several returns we reviewed:

• The couple qualified
• The math worked
• But the deduction wasn’t applied

Why?

A simple box wasn’t checked in the tax software.

In some cases, that meant missing out on $2,000+ refunds (until we showed them how to claim the deduction).

Watch: How This Works in Real Life

I recently talked about Wisconsin retirement tax rules here:

It’s a quick overview, but it’ll give you a feel for how these decisions actually play out.

Potential Tax Savings

So how much could this new rule save you?

• If you’re in Wisconsin’s 4.4% tax bracket, excluding $24,000 of retirement income saves you about $1,056 per year.
  
• If you’re in the 5.3% tax bracket, that savings jumps to around $1,272 per year.
  

Multiply that by two for a married couple, and the savings add up fast—potentially over $2,000 each year.

Of course, you would miss out on some credits, often the up to $300 School Property Tax Credit, which is why it’s important to compare whether you are better off taking the deduction, or taking the individual credits.

Planning Opportunities

This new rule also opens up some tax planning opportunities:

1. Perhaps delay Roth Conversions Until After 67
   If you’re nearing 67, you may want to wait before completing Roth conversions. In states like Illinois, where retirement income is totally excluded, many retirees have converted hundreds of thousands of dollars without paying state income tax. Wisconsin retirees now may have a similar opportunity.
   
2. Coordinate Between Federal and State Taxes
   While this Wisconsin exclusion is fantastic, don’t forget about federal taxes. They still apply to your retirement income. Always weigh both sides before making decisions.
   
3. Make Sure You Review Your Tax Return BEFORE You file
   Many people get their tax return from their tax preparer just before the tax deadline, they discuss the joy, or pain, from their refund (or payment due), and they try to get out of the office as soon as they can.
   
   Instead, you should have your tax preparer walk you through your tax return, line by line, so that you can both be certain you didn’t miss anything. And if you’re 67+ in Wisconsin ask specifically if they compared your credits against this new Wisconsin Retirement Income Subtraction so that you know which way worked better for you.
   

Putting It All Together

This isn’t just a tax rule.

It’s part of a bigger decision:

• How to turn your savings into income
• While paying less tax over time

And that’s where most retirees need help—not filling out the form, but making the right decisions before the form is ever filed.

But remember—this is just one piece of the puzzle. Tax planning should always be part of a bigger retirement strategy that also considers your income needs, investment growth, and long-term healthcare costs.
