When a “Free” Tax Preparer Almost Cost $10,000 in Minnesota Penalties

In this real case work story, an Illinois resident thought she was lucky because her boss had “a guy” who would do her tax return for free. A few years later, the Illinois Department of Revenue sent a notice tied to missing Minnesota income and withholding, demanding roughly $10,000 in tax, penalties, and interest. Here’s what she came to me with, what I did before we ever met, how I uncovered the real problem, and how we fixed both the state piece and the 1040.

At the time all this started, the taxpayer was living in Illinois and working remotely for a company that paid wages out of Minnesota. Her W-2 showed Minnesota-source wages and Minnesota withholding, even though she never physically moved there.

Her boss connected her with a tax preparer who “takes care of employees” and “does it free.” No fee, no online software, no stress — or so it seemed.

What she came to me with

A few years later, she received a letter from the Illinois Department of Revenue. The notice essentially said:

  • There was missing or mismatched W-2 information involving Minnesota wages,
  • The returns on file did not properly reflect that Minnesota income and withholding, and
  • Illinois now wanted tax, penalties, and interest that added up to roughly $10,000.

She was confused. She knew that Minnesota tax had been withheld from her paychecks, and she assumed the “free” preparer had handled everything correctly — including any nonresident Minnesota filing and the interaction with her Illinois resident return.

Her questions to me were simple: “Why is Illinois coming after me over Minnesota?” and “Is this really my fault?”

What I did before we ever sat down

Before our first real conversation, I wanted to see the story through the eyes of both states and the IRS. I asked her to securely upload:

  • The full Illinois notice (every page),
  • A copy of the original federal 1040 and Illinois return the “free” preparer had filed,
  • Any Minnesota paperwork — especially the W-2 showing Minnesota wages and withholding, and
  • Any prior correspondence about a Minnesota nonresident return (Form M1NR) if it existed at all.

With those in hand, I spent time on three things before our meeting:

  • Reading the Illinois notice in detail to see exactly what year and what part of the return was being challenged.
  • Comparing the W-2 to the returns to see whether Minnesota wages and withholding appeared anywhere on the 1040 or Illinois schedules.
  • Checking for a Minnesota nonresident return (M1NR) and any sign that Minnesota income had been properly reported there.

By the time we spoke, I already had a working theory: the “free” return had ignored both the Minnesota piece and the way Illinois expects you to report and reconcile it.

What I discovered: missing Minnesota everywhere

As I traced the numbers, a few key problems appeared:

  • The W-2 clearly showed Minnesota wages and Minnesota withholding.
  • Those Minnesota wages were missing from the federal 1040 — the income total did not include them.
  • The Illinois return also did not clearly reflect that Minnesota-source income or the related withholding on its schedules (including Illinois’ W-2/withholding schedule).
  • There was no proper Minnesota nonresident filing (Form M1NR) in the mix to show Minnesota that income and tax either.

In practice, that meant:

  • Minnesota saw wages and withholding reported by the employer, but that income and withholding were not correctly matched to a nonresident return.
  • Illinois saw that something was off around out-of-state wages and withholding and flagged the Illinois return through its notice process.

From the states’ perspective, it looked like the taxpayer had not properly reported the income or the withholding anywhere. That’s how we ended up with a notice asking for the withholding, plus substantial penalties and interest.

Key takeaway: When a return leaves out entire chunks of out-of-state income and withholding, states don’t assume “harmless oversight.” Their systems assume tax is missing — and they bill you accordingly.

Building the fix: Minnesota, Illinois, and the 1040

Once we confirmed the facts, I explained that we needed to clean up three layers so they all told the same story:

  • The Minnesota nonresident piece (M1NR and related schedules),
  • The Illinois resident return and its withholding schedule, and
  • The federal 1040 where the income had been missing entirely.

Step 1 – Fix the Minnesota nonresident picture (M1NR)

For Minnesota, the goal was to:

  • File or correct the nonresident Minnesota return (Form M1NR) to show the Minnesota-source wages, and
  • Properly report the Minnesota withholding that the employer had already sent to the state.

That way, Minnesota’s records would show:

  • “Yes, this taxpayer had Minnesota wages,” and
  • “Yes, Minnesota withholding was applied to those wages on a return, rather than floating unclaimed.”

Step 2 – Correct Illinois’ view, including its withholding schedule

On the Illinois side, I focused on:

  • Refiling the Illinois return with all income properly included, including the Minnesota wages that had been left out.
  • Correcting the Illinois withholding / W-2 schedule (such as the Schedule W-2) so it accurately showed that tax had been withheld in Minnesota.
  • Making sure any credit for tax paid to another state was handled in line with Illinois rules, once Minnesota was properly reported.

In the response to the Illinois notice, I was able to explain:

  • That the original “free” return had failed to reflect the Minnesota situation,
  • That we had corrected the Minnesota side with M1NR and updated withholding reporting, and
  • That the revised Illinois return now matched the actual wage and withholding data on file with the states.

Step 3 – Amend the 1040 so federal matches the states

Finally, I addressed the federal 1040. If we had left it alone, the IRS would still see W-2 wages that never made it onto the federal return — a recipe for future CP2000-type notices.

So I:

  • Amended the 1040 to include the missing Minnesota wages in total federal income.
  • Recomputed the tax due at the federal level with that income included.
  • Checked that the amended 1040, the Minnesota M1NR, and the corrected Illinois return all told the same consistent story.

Now, all three pieces — Minnesota, Illinois, and the IRS — were aligned.

The outcome: big penalty wiped out, problem contained

After the corrected filings and explanations were submitted, the outcome we were aiming for — and achieved — was:

  • The large Illinois balance and penalty tied to “missing” Minnesota wages and withholding was removed or dramatically reduced, because the withholding was now properly documented and applied.
  • The taxpayer’s federal position was clean, with no unreported Minnesota wages lingering in the background.
  • Both states now saw the same wage and withholding story, backed by actual forms rather than assumptions.

The real win, from my perspective, was that the taxpayer now understood why the problem happened and how we fixed it — not just that a scary number changed on a letter.

Lesson: When your return involves wages from one state while you live in another, “free” or rushed prep can easily miss entire pieces like a nonresident return, a Schedule W-2, or the credit for tax paid to another state. Those gaps are exactly what state computers are built to find.

Why I’m documenting case work like this

Stories like this aren’t marketing copy — they’re case work. I write them down to:

  • Keep a timeline of what actually happened and how we solved it,
  • Show future clients real examples of the problems we handle, and
  • Remind myself and my team of the steps that worked when we face similar patterns again.

If a regulator or another professional ever asked, “How have you handled multi-state W-2 notices in the past?”, this kind of case work entry gives us a clean, public record of our approach — without exposing any client’s identity.

Used a “free” or cheap preparer and now have a notice?

If your return involves one state on paper and another on your W-2, and now a notice has arrived, you don’t have to guess what to do next. Send the notice, the returns, and the W-2s — I’ll help you rebuild the story so the states and the IRS all see the same reality.
