Civil Return-Preparer Fraud

The IRS and Department of Justice actively pursue civil injunctions against tax return preparers suspected of filing false returns or engaging in fraudulent tax schemes.

These cases are brought under 26 U.S.C. §§ 7407, 7408, and 7402(a), allowing the government to seek broad court orders that can restrict, or permanently bar, individuals and businesses from preparing or assisting in the preparation of tax returns.

Although civil in form, preparer injunction cases can carry severe financial and reputational consequences — and often parallel, or even precede, criminal investigation

Statutory Framework

The government may seek injunctions under three principal statutes:

  • § 7407 – Return Preparer Injunctions.
    Allows injunctions against tax return preparers who engage in conduct such as:

    • Preparing fraudulent or false returns,

    • Misstating income, deductions, or credits,

    • Fabricating dependents or withholding, or

    • Otherwise demonstrating a “pattern” of fraudulent conduct.
      Courts can impose a narrow injunction (prohibiting specific practices) or a permanent injunction (barring all preparation activity).

  • § 7408 – Promotion of Abusive Tax Shelters or Schemes.
    Authorizes injunctions against anyone promoting abusive tax strategies, such as false deductions, improper credits, or sham trusts marketed to reduce tax liability.

  • § 7402(a) – Broad Equitable Powers.
    Grants courts authority to issue any injunction necessary to enforce the internal revenue laws — even beyond §§ 7407 and 7408 — often used to stop related conduct like interfering with IRS examinations or obstructing enforcement.

How DOJ and IRS Build These Cases

The government usually initiates these actions following IRS civil examinations or Return Preparer Program investigations. Common evidence includes:

  • Statistical analysis of returns prepared by the defendant showing systematic overstatement of deductions or credits,

  • IRS interviews of taxpayers who used the preparer,

  • Copies of sample returns with common misstatements,

  • Electronic Filing Identification Number (EFIN) data and preparer tax identification records, and

  • Correspondence showing awareness of improper conduct.

Because the remedy is equitable, DOJ need not prove intent beyond a reasonable doubt — only by a preponderance of the evidence that the conduct was unlawful and likely to recur.

Consequences of an Injunction

An injunction can:

  • Shut down a tax-preparation business entirely;

  • Require the preparer to disgorge profits from preparation fees;

  • Mandate production of client lists and records;

  • Allow the IRS to contact the preparer’s clients for examination; and

  • Serve as a predicate for later criminal charges under § 7206 or § 7207 (false returns).

Even limited injunctions often have devastating practical effects — reputational harm, loss of livelihood, and the possibility of follow-on enforcement.

Defending Against a Preparer Injunction Case

Defense strategy often turns on attacking the government’s statistical or pattern-based evidence and showing lack of willfulness or knowledge. Common defenses include:

  • Demonstrating isolated errors or client-provided misinformation rather than a systematic pattern;

  • Challenging the scope and reliability of IRS sampling or audit data;

  • Showing the preparer relied in good faith on client representations or professional software;

  • Arguing that the proposed injunction is overbroad or punitive rather than remedial; and

  • Negotiating consent injunctions with limited, tailored restrictions to avoid full business shutdowns.

Where possible, early internal review of sample returns and communications is critical to assess exposure and preserve defenses before the DOJ files suit.

Overlap with Criminal Exposure

Although injunction suits are civil, they are often referred from IRS Criminal Investigation or parallel to grand jury inquiries. Admissions, depositions, or document productions in the civil case might later be used in a criminal prosecution. Counsel must manage both fronts carefully — protecting against inadvertent self-incrimination while pursuing civil resolution.

Return preparer injunction actions are among the most aggressive civil enforcement tools the IRS and DOJ possess. They can shut down an entire practice, destroy reputation, and lead to criminal prosecution if not handled with care.

Because these cases often hinge on technical tax issues, sampling methodology, and client testimony, success requires early factual analysis, expert assistance, and experienced counsel able to engage both the IRS and DOJ on equal footing.
