The IRS completed 2,850 criminal investigations in three areas in FY 2025. Of those, 1,085 were legal-source tax crime cases involving activities, industries, and occupations that generate legitimate income or threats to the tax system.
The other 1,195 are illegal-source financial crime cases. These relate to proceeds derived from unlawful sources such as money laundering. The other 570 cases are linked to financial crimes involving narcotics-related tax and money-laundering crimes.
An audit letter is unsettling for anyone, but most audits end with a bill, not an arrest.
The distinction between a civil finding and a criminal case is one of the least understood parts of the process, and understanding where that line sits matters enormously for anyone who’s just been notified that irregularities were found in their return, claim, or filing.
Most often, individuals are prosecuted only if they intentionally avoid fulfilling their fiscal obligations under the legislation or engage in deliberate fraudulent practices. Authorities are at liberty to launch a criminal case in situations of this kind.

Most Fraud Audits Stay Civil, Not Criminal
Audits that reveal difficulties most often lead to civil sanctions, with no criminal charges.
As for issues on tax specifically, the IRS audits more than 1.5 million individual income tax returns on an annual basis, but the number of cases actually referred for criminal prosecution runs only in the low thousands.
The takeaway isn’t that fraud goes unpunished. It’s that the civil and criminal tracks are genuinely separate, and most violations, even real ones, get resolved on the civil side.
What Separates a Civil Finding From a Criminal Referral
Though some are selected randomly, most audits are triggered when the system software used by the IRS notices inconsistencies or signs of tax fraud. But what happens if you are audited and found guilty?
The distinction hinges on intent and effort.
A civil audit finding typically involves an honest mistake, a misunderstood rule, or a simple miscalculation. In most cases, a criminal referral will require proof that someone intended to defraud the IRS and not just that a figure on a form was mistaken.
Such a scenario would expose one to concealed financial records, inaccurate information relayed to a specialist in the course of any examination, multiple deliberate miscalculations rather than just one-time negligence, or a cover-up in the middle of an audit.
The conditions mentioned can reflect an evolving situation in a simple commercial tax issue into something much more serious, which comprises a legal aspect and demands a criminal investigation in earnest.
Civil Penalties Alone Can Still Be Severe
Even when a case never becomes criminal, civil penalties for fraud findings are far harsher than penalties for an honest error.
A civil fraud penalty is typically calculated as a steep percentage of the underpayment or overstated claim, on top of the amount actually owed. Interest will continue to accumulate throughout the process.
These penalties exist specifically since civil fraud findings require proving a real intent to deceive, even without meeting the higher bar for criminal charges. The law treats that intent as something worth punishing severely on its own.
A Criminal Referral Changes Everything About the Process
Once a case crosses into criminal territory, everything about it changes.
The government’s burden of proof rises from the civil standard to proof beyond a reasonable doubt, a much higher bar, but the consequences rise correspondingly. Criminal fraud convictions carry the possibility of actual prison time in addition to fines and restitution.
Unlike a civil penalty, a criminal conviction becomes part of a permanent criminal record.
The investigation itself also looks different, often involving law enforcement agents rather than a routine auditor. It will reach much further back into records, communications, and financial history than a standard civil examination would.
A Lafayette fraud lawyer typically gets involved at exactly this point. The moment an audit shows signs of turning criminal is usually the last real opportunity to influence which track the case follows.
Cooperation Doesn’t Guarantee a Civil-Only Outcome, But It Genuinely Helps
How someone responds during an audit can meaningfully affect its outcome. Being forthcoming, providing accurate documentation, and correcting errors voluntarily before an examiner discovers them independently all tend to support a civil resolution rather than a criminal one.
If an individual intentionally omits giving documents or gives incorrect information to a revenue officer, such acts become significant factors for consideration in organizing an audit.
It’s normal for anyone to make errors. The instinct to hide these mistakes out of embarrassment is natural. What is wrong is deliberately hiding information that is essential. The lack of full disclosure during an audit can only worsen your position.
What to Do the Moment Fraud Indicators Appear
Anyone notified that an audit has identified potential fraud indicators, rather than a routine adjustment, should treat that notification seriously. Get legal guidance immediately before responding further to any questions from an examiner.
Statements made early in an audit, before anyone fully understands whether the matter might turn criminal, can end up shaping the entire trajectory of the case. Getting experienced guidance at that early stage is the single most effective thing anyone facing a fraud audit can do to protect their position.
None of these factors means every audit finding leads somewhere serious. Most don’t. But knowing the difference between a routine civil correction and the early signs of a criminal referral is the kind of knowledge that determines which direction a case actually goes.
