Tax season in Minnesota is stressful enough without wondering whether a filing error could land you in serious legal trouble. And frankly, that concern is not as far-fetched as it sounds. Most people who make mistakes on their taxes never face criminal prosecution. But some do. Understanding where that line sits, and what pushes a case across it, matters more than most people realize.
At Mauzy Law, we work with clients facing serious financial and criminal allegations, including cases that began as a tax audit and escalated into something far more consequential. Tax-related offenses fall squarely within the realm of white collar and economic crimes, and the consequences of a criminal conviction in this area can be severe. A felony on your record, significant fines, and potential prison time are all real possibilities once a case crosses from civil territory into criminal territory.
The Core Distinction: Mistakes vs. Willful Intent
The single most important concept in any tax case is willfulness. Fraudulent intent is required for civil fraud; willfulness is required for many criminal tax offenses. It is generally understood as a conscious, knowing decision to do or fail to do some act. Without the required criminal intent, there is no criminal tax case.
The tax codes are long and dense and sometimes nearly indecipherable, even for accountants paid to make sense of them. The IRS and the Minnesota Department of Revenue both acknowledge this reality. Simple mathematical errors or misunderstanding complex provisions of the tax code are typically not considered fraud. The IRS recognizes that tax laws are complex and honest mistakes occur frequently among taxpayers attempting to fulfill their legal duty to file accurate returns and pay taxes.
So where does an honest mistake end and criminal conduct begin? Intent. The difference between negligence and fraud is intent. But intent is not written on the tax return. It is a judgment call. And that judgment call gets made by investigators, auditors, and prosecutors who are trained to look for specific patterns.
Three Levels of Tax Problems: Negligence, Civil Fraud, and Criminal Fraud
Not all tax problems are created equal. There is a meaningful legal difference between a careless mistake, civil fraud, and criminal tax fraud. Each carries different consequences.
Negligence means you made an error without intending to deceive anyone. Negligent errors may result in accuracy-related civil penalties of around 20% but rarely lead to criminal charges. You pay what you owe, plus a penalty, and move on. No felony. No prosecution.
Civil tax fraud is more serious. Civil tax fraud means the IRS believes you intended to lie on your tax return, whether by omitting income on purpose, including false deductions you knew were improper, or failing to report offshore income. The burden of proof is on the IRS to prove intentional conduct by clear and convincing evidence, which is more difficult than assessing a simple negligence penalty, but not as difficult as the beyond a reasonable doubt standard required in a criminal case.
Criminal tax fraud is a different matter entirely. Criminal allegations are pursued to punish the individual for the commission of tax fraud and to deter the individual and others going forward. The defendant faces fines, restitution, and imprisonment as possible consequences of conviction.
What Investigators Actually Look For
According to the IRS, indicators of fraud, also known as badges of fraud, may include consistently underreporting income, making false statements to IRS agents, or destroying financial records. These are the kinds of patterns that cause an audit to shift into a criminal investigation.
Consider a scenario: a Minneapolis area business owner has been depositing significant cash revenue for several years without reporting it. The amounts are not trivial. Each year, the reported income is substantially lower than what bank records show. The owner’s explanation is that the bookkeeping was disorganized. That explanation might work once. It rarely works across multiple tax years with consistent, significant gaps between deposits and reported income. At some point, investigators stop seeing disorganization and start seeing a pattern.
The IRS may begin with a civil examination but refer cases for criminal investigation and recommend prosecution when evidence suggests tax fraud. That transition can happen faster than most people expect, and it often happens without the taxpayer realizing the investigation has escalated.
How an Attorney Can Help
Most people contact an attorney after they have already received a notice, responded to an auditor, or said things they should not have said. That timing creates challenges. Once a criminal investigation begins, taxpayers should exercise their right to remain silent and obtain legal representation immediately.
We encourage clients to reach out well before that point. If you are under audit, if you have received inquiries from the Minnesota Department of Revenue or the IRS, or if you know there are years where your filings were inaccurate, that is the time to talk to an attorney. Not after the investigation has escalated.
The law provides a meaningful distinction between a mistake and a crime. But that distinction does not protect itself. It requires someone who understands how these cases develop and how to present your situation accurately and effectively.
