Return-Preparer Fraud: Criminal vs Civil Fraud

Tax return preparers—whether CPAs, enrolled agents, or independent professionals—can face serious scrutiny from the IRS and Department of Justice if the government believes they filed or helped file false returns. What many don’t realize is that there are two very different paths such a case can take: civil injunction actions and criminal prosecutions.

Understanding the difference—and the stakes—is essential if you’re under IRS investigation or have been contacted by the DOJ.

1. The Civil Path: Injunction Actions and Penalties

Civil return preparer cases fall under 26 U.S.C. §§ 7407 and 7408, which allow the government to seek an injunction (a court order) stopping a preparer from:

• Preparing returns for others,

• Promoting abusive tax schemes, or

• Engaging in conduct the IRS deems fraudulent or misleading.

Civil cases are filed in federal district court. The burden of proof is preponderance of the evidence—a much lower standard than criminal cases. That means the government only needs to show it’s more likely than not that the preparer engaged in the alleged conduct.

The IRS may also pursue civil penalties (under sections like § 6694 or § 6701) for understatement of tax liability or aiding in the preparation of false documents. While civil cases don’t carry prison time, the injunction and reputational fallout can be career-ending.

2. The Criminal Path: Felony Prosecution

Criminal return preparer cases are typically charged under 26 U.S.C. § 7206(2) (aiding and assisting in the preparation of a false return). The burden of proof is much higher: the government must prove beyond a reasonable doubt that the preparer willfully prepared or helped prepare a false return.

“Willfulness” means a voluntary, intentional violation of a known legal duty—not just negligence or sloppiness. The government often looks for:

• Patterns of inflated deductions or credits,

• High refund claims,

• Copy-and-paste errors across many returns, and

• Evidence of concealment or cash payments.

A single return can trigger a broader lookback. Once a pattern emerges, the IRS Criminal Investigation Division (IRS-CI) or DOJ Tax Division may step in.

Criminal cases carry heavy consequences: up to three years in prison per count, fines, restitution, and potential loss of professional credentials.

3. Discovery and Fifth Amendment Concerns

Civil and criminal cases may look similar at the start—but the discovery rules once in federal court are completely different.

• In a civil injunction case, the government can use depositions, interrogatories, and document requests.

• In a criminal case, discovery is tightly controlled under Rule 16 of the Federal Rules of Criminal Procedure, and the defense gets access to evidence only after indictment.

But here’s the trap: a civil administrative case can become criminal. And if a preparer is sued civilly while a criminal investigation is pending, every deposition, affidavit, and document response carries Fifth Amendment risk. Testimony meant to defend the civil case can later be used to prosecute the criminal one.

For that reason, defense counsel often considers asserting the Fifth Amendment or seeking a stay of the civil case until any parallel criminal investigation concludes. The Fifth Amendment, however, offers limited protection in a civil case as compared to its value in a criminal case.

4. Relief and Resolutions

• Civil: The government seeks an injunction (a court order restricting or banning future preparation), civil penalties, and attorney’s fees. These cases may settle if the preparer agrees to limited restrictions or compliance monitoring.

• Criminal: The government seeks conviction, restitution, and deterrence. Resolution often involves plea discussions or trial.

When the Stakes Are High

Return-preparer cases sit at the intersection of tax, fraud, and professional liability. The difference between civil and criminal exposure often turns on intent, patterns, and how the preparer responds early on. If you’re contacted by the IRS or DOJ about your return preparation business, take it seriously—but don’t panic. With early counsel, it’s often possible to limit exposure, protect your rights, and keep a civil inquiry from becoming a criminal case. Mendoza Defense is here to help when the stakes are high.
