When a Michigan divorce attorney uncovers incorrect—or even fraudulent— past income tax returns, the question clients ask most often is deceptively simple:
“Do I have to amend the return?”
But the answer is far more nuanced than most people expect.
For more than 30 years, The Kronzek Firm has represented clients in complex and high‑asset divorces across Mid‑Michigan. One of the most sensitive issues we encounter is how to handle income tax returns that contain errors, omissions, or intentional misstatements. While honesty is essential, amending a tax return is not always the safest or smartest move during a divorce.
This guide explains when you must amend, when you should not, and how to make the decision strategically. This is not tax advice. We are not tax preparers, enrolled agents, tax attorneys, or CPAs. Always consult with a qualified tax professional before you make any important tax decisions.
Why This Question Matters During Divorce
Tax returns are often the single most important financial document in a Lansing divorce case. They influence:
- child support
- spousal support
- business valuations
- property division
- credibility assessments
When errors surface—whether innocent or intentional—they can have legal, financial, and even criminal implications. But that does not mean an amendment is always required. We’re providing some general information, which you should always verify with a tax professional.
When You Must Amend a Tax Return
There are situations where amending is not optional. These include:
1. Missing Income Documents (W‑2s, 1099s, K‑1s)
If the IRS receives income documents that you did not include, their automated matching system will eventually flag the discrepancy.
Failing to amend can lead to:
- interest
- penalties
- accuracy‑related fines
- potential fraud allegations
2. Errors That Increase Your Tax Liability
If the mistake results in additional tax owed, you are legally obligated to correct it.
Waiting for the IRS to catch up only increases penalties.
3. Federal Changes That Affect Michigan Taxes
Michigan law requires taxpayers to file an amended state return within 180 days of a final federal adjustment. This is not optional.
When You Should Not Amend a Tax Return
This is where strategy becomes essential. There are many situations where amending a return may hurt you more than it helps, especially during a contentious divorce. Your divorce attorney should coordinate with your income tax preparer before making a tax decision.
1. When the Amendment Could Trigger an Audit
Amended returns often receive extra scrutiny.
High‑risk triggers include:
- Earned Income Tax Credit
- Qualified Business Income Deduction
- Schedule C businesses
- Rental losses
- Large charitable deductions
If the amendment is minor and the risk is high, a CPA or other tax expert may advise against filing.
2. When the Amendment Could Expose You to Criminal Liability
If the return contains intentional fraud, amending it may:
- admit wrongdoing
- restart the statute of limitations
- expose you to prosecution
In these cases, the decision must be made with both a CPA and a criminal‑tax attorney.
3. When the Amendment Would Benefit Your Spouse
During a divorce, amending a return may:
- Increase joint refunds your spouse can claim
- Increase income used for support calculations
- Strengthen your spouse’s claims of misconduct
Sometimes the better strategy is to disclose the issue in the divorce without amending the return.
4. When the Refund Is Too Small to Justify the Risk
Many tax professionals use the “chip in your pocket” strategy:
If the amendment would produce a small refund, it may be safer to keep the documentation and use it only if the IRS audits you later.
The Biggest Misconception: “You Have Three Years to Amend”
This is only partially true.
- The IRS allows three years to claim a refund.
- Michigan requires amended returns within 180 days of a final federal determination.
These timelines are not interchangeable.
How to Make the Decision Safely
Because tax law is complex and the consequences can be severe, we always advise clients to consult:
- A CPA or other tax expert
- A tax attorney (if fraud is suspected)
- Your divorce attorney working with your tax preparer
The decision must balance:
- tax liability
- audit risk
- criminal exposure
- divorce strategy
- timing
- financial impact
There is no one‑size‑fits‑all answer.
The Bottom Line
Incorrect or fraudulent tax returns discovered during a Michigan divorce should not automatically be amended.
Sometimes an amendment is legally required.
Sometimes it is strategically unwise.
Sometimes it is dangerous.
The key is understanding the risks, timing, and broader implications of your divorce.
If you are facing this dilemma, The Kronzek Firm can help you navigate the legal and strategic issues involved in protecting your financial future.
FAQ: Amending Incorrect or Fraudulent Tax Returns During a Michigan Divorce
1. Do I have to amend a tax return if I discover an error during my divorce?
Not always. Some errors legally require correction (such as missing W‑2s or 1099s), while others may expose you to unnecessary audit risk or even criminal liability. The decision must be made with a CPA, tax attorney, or other tax professional, along with your attorney.
2. Will the IRS find out if I don’t amend a return?
If the IRS has income documents you didn’t report, their automated matching system will eventually detect the discrepancy. For minor errors that don’t affect reported income, the IRS may never flag the issue.
3. Can amending a tax return trigger an audit?
Yes. Amended returns often receive additional scrutiny, especially when they involve refundable credits, business deductions, or rental losses. This is one of the main reasons amendments must be evaluated strategically.
4. Could amending a fraudulent return expose me to criminal charges?
Potentially. Filing an amended return may be interpreted as an admission of wrongdoing. If fraud is involved, you must consult a tax attorney before taking action.
5. Does Michigan require amended state returns if I amend my federal return?
Yes. Michigan law requires taxpayers to file an amended state return within 180 days of a final federal adjustment. This is mandatory.
6. Will amending a return affect child support or spousal support calculations?
It can. Corrected income may increase or decrease support obligations. In some cases, amending a return may benefit your spouse more than you.
7. What if the amendment results in a refund?
If the refund is small, the risk of triggering an audit may outweigh the benefit. Many tax professionals recommend keeping the documentation and using it only if the IRS audits you later.
8. Can my spouse force me to amend a tax return during divorce?
No. A spouse cannot force you to amend a return. However, the court can consider tax irregularities when determining credibility, support, or property division.
9. What if my spouse filed fraudulent returns without my knowledge?
You may qualify for Innocent Spouse Relief or Injured Spouse Relief, depending on the circumstances. These are IRS programs designed to protect spouses who were unaware of tax misconduct.
10. What should I do first if I discover a problem with past tax returns?
Before taking any action, consult:
- A CPA or other experienced tax professional
- Your divorce attorney
- A tax attorney (if fraud is suspected)
Do not amend anything until you understand the legal and strategic consequences.
