Tax fraud is more common than most people realize, and it can happen to anyone-even when you’re working with a professional. At Law Offices of Scott B. Saul, we’ve seen firsthand how fraud tax return filing can damage your finances and create years of complications with the IRS.

If you suspect something is wrong with your tax return, acting fast matters. This guide walks you through the warning signs, how to report fraud to the IRS, and steps to protect yourself going forward.

What Fraud Looks Like on Your Tax Return

Your Preparer Should Show You Everything

Your tax preparer or accountant must be transparent about every line item on your return. If they file without showing you the completed form first, that’s a red flag. Some preparers rush clients through the signing process or claim the return is too complicated to explain-this behavior indicates they may be hiding something. The IRS Criminal Investigation division reports that preparers committing fraud often file returns without client knowledge or consent. Always insist on reviewing your full return before it’s filed, and request detailed explanations for any deductions or credits you don’t recognize. If your preparer resists this step, find someone new immediately.

Spot Mismatched Numbers and Missing Records

Deductions and income figures that don’t match your actual financial records are another warning sign. Review your W-2s, 1099s, and bank statements against what appears on your return-the numbers should align exactly. Inflated deductions for home office expenses, vehicle mileage, or charitable contributions, or income that’s been mysteriously reduced, suggest deliberate manipulation. Missing documentation is equally concerning; your preparer should maintain copies of receipts, invoices, and supporting papers for every claimed expense.

If you ask for documentation and they cannot produce it, the IRS will reject those deductions during an audit, leaving you responsible for back taxes, penalties, and interest. Keep your own copies of all tax documents for at least seven years and request written confirmation from your preparer about what documentation they’re retaining. If discrepancies emerge between what you provided and what was filed, document this immediately and consider filing an amended return to correct the errors before the IRS initiates contact.

Act Before the IRS Contacts You

The moment you spot irregularities on your return, you face a choice: wait for the IRS to discover the problem, or take control of the situation yourself. Filing an amended return demonstrates good faith and significantly reduces the penalties you’ll face. The IRS treats taxpayers who self-report fraud far more favorably than those caught during an audit. Once you’ve identified the fraud and corrected your records, you’ll need to understand the formal reporting process-which involves specific forms and channels designed to protect both you and other taxpayers from similar schemes.

Report Tax Fraud to the IRS

Choose the Right Reporting Form for Your Situation

When you identify fraud on your tax return, the IRS offers multiple reporting pathways. Form 3949-A handles suspected tax fraud or violations not covered by specialized forms. This form works for cases involving false exemptions, unreported income, inflated deductions, or altered tax filings. You submit it with all supporting documentation: copies of the fraudulent return, your corrected version, bank statements showing actual income, receipts proving legitimate expenses, and any correspondence with your preparer. The IRS accepts Form 3949-A submissions by mail to your local IRS office, and processing typically takes several months as investigators review your evidence.

The strength of your case depends entirely on specificity and documentation. Vague complaints without proof won’t trigger an investigation. Gather everything before submitting: dates of fraudulent filings, names and contact information for the preparer or person who committed fraud, amounts of false deductions or unreported income, and a clear timeline of events.

Pursue a Monetary Award Through the Whistleblower Program

The IRS Whistleblower Office pays for information that leads to collected proceeds exceeding $2 million in taxes, penalties, interest, and other amounts. You file Form 211 instead of Form 3949-A, which requires your name, signature, and detailed facts about the fraud. Anonymous tips don’t qualify for awards-the IRS needs your identifying information and your willingness to sign under penalty of perjury.

The Whistleblower Office emphasizes that awards go only to credible information that actually results in collections. Awards generally range from 15 to 30 percent of collected proceeds. Processing takes time: the IRS evaluates your claim, investigates, pursues collection, and then determines your award eligibility. This pathway makes sense if you possess substantial evidence of large-scale fraud.

Report Money Laundering and Wire Schemes to FinCEN

For fraud involving money laundering, cryptocurrency, or wire schemes, report to FinCEN (Financial Crimes Enforcement Network) instead of standard IRS channels. FinCEN coordinates with federal agencies to track financial crimes across borders and jurisdictions. Include details about financial pathways (crypto assets, shell companies, wire transfers) when submitting your report.

Contact the Criminal Investigation Division for Serious Cases

The Criminal Investigation Division handles the most serious cases, typically those involving organized fraud rings or preparers systematically defrauding dozens of clients. Direct contact with CI requires coordination through an IRS agent or attorney, as they investigate criminal violations that may result in prosecution. These cases move beyond civil penalties into potential jail time and criminal records for the perpetrators.

Understanding which channel fits your situation determines how quickly the IRS can act. Once you’ve submitted your report through the appropriate form, the investigation process begins-but your role doesn’t end there. You’ll need to protect yourself from future fraud while the IRS works on the case, which means taking specific steps to monitor your tax records and prevent similar schemes from happening again.

How to Vet and Monitor Your Tax Preparer

Verify Credentials Before You Hire

The IRS Criminal Investigation division reports that preparers committing fraud often operate for years before detection, sometimes filing false returns for dozens of clients simultaneously. Your first line of defense is verification before you hire anyone. Check this tool to research tax return preparers near you or to determine the type of credentials or qualifications held by a specific tax professional. The IRS maintains a directory of tax professionals, and you can verify licensing status through your state’s accounting board or bar association. Ask directly whether your preparer has ever faced disciplinary action, sanctions, or complaints-legitimate professionals answer without hesitation.

Request References and Follow Up

Request references from other clients and follow up by calling them to ask whether the preparer explained every deduction and provided copies of filed returns. A preparer who refuses to provide references or becomes defensive about their history is someone to avoid entirely. Trust your instincts when a professional resists transparency; that resistance signals potential problems down the road.

Review Your Return Line by Line

Once you’ve hired someone, your responsibility doesn’t end. Review your completed return line by line before you sign anything, comparing every figure against your W-2s, 1099s, bank statements, and receipts. The IRS expects you to understand your own tax situation; signing a return you haven’t thoroughly reviewed leaves you liable for penalties and back taxes even if your preparer committed the fraud. Keep digital and paper copies of all documents you provide to your preparer and request written confirmation of what they’re retaining for their records.

Monitor Your Social Security Number Actively

Monitor your Social Security number actively by checking free weekly credit reports from Equifax, Experian, and TransUnion. If you notice accounts you didn’t open or inquiries from creditors you don’t recognize, contact the Federal Trade Commission immediately at identitytheft.gov. Consider placing a credit freeze with all three bureaus if you’ve already been victimized (this costs nothing and prevents criminals from opening new accounts in your name). The IRS Taxpayer Protection Program flags suspicious returns automatically, but your personal vigilance catches fraud faster than any government system.

Final Thoughts

Reporting fraud tax return filing requires you to act on multiple fronts simultaneously. File an amended return if you discover errors on your own return, then submit Form 3949-A with complete documentation to your local IRS office. For large-scale fraud exceeding $2 million in collected proceeds, pursue the Whistleblower Program using Form 211 for potential monetary awards, while money laundering or cryptocurrency schemes warrant direct reporting to FinCEN.

Prevention protects you as effectively as reporting does. Verify your tax preparer’s credentials through the IRS directory and your state’s accounting board before hiring anyone. Review your completed return line by line against your W-2s, 1099s, and receipts before you sign, and monitor your Social Security number by checking free weekly credit reports from all three bureaus.

Speed determines your outcomes with the IRS. The agency treats taxpayers who self-report fraud far more favorably than those caught during audits, and acting quickly protects your refund while reducing penalties.
