How to Report Tax Fraud

Tax fraud costs the U.S. government around $90 billion in revenue every year. That’s bad for all of us. We rely on fiscal revenue to finance infrastructure, health, and education. Those who commit tax fraud or tax evasion make life harder for the average citizen. We all have a civic duty to report these people when we know about their misdeeds. This article will
explain how to do that.

What is Tax Fraud?

Tax fraud is when a person or business intentionally falsifies information on their return to pay fewer taxes. Falsifying your tax return is a felony crime that can cost you huge fines, time behind bars, or both. Also, attempting to evade your taxes is about as serious as fraud offenses go.

If someone knowingly doesn’t pay all of their taxes and gets caught, they will be sentenced could be looking at up to five years of jail time, a penalty of up to $250,000, or both.

On the other hand, those starting a business or even established corporations face a fine of up to $500,000, three years behind bars, or both when caught falsifying a return, lying about their income, making false deductions, or reporting dishonest charity contributions.

Different Types of Fraud

There are many types of fraud and fraud schemes. Below are the most popular types of tax fraud that people and corporations commit.

Unreported Income


People often try to avoid paying taxes by not reporting income. Unreported income is when someone illegally excludes mentioning their income in their tax return.

Tax Refund Scam


A tax refund scam involves identity theft, forged W-2 forms, and illegally filing a tax return using another person’s name to receive a tax refund in your bank account.

You can know if you are a victim of a tax refund scam when the IRS sends you a letter stating that there are multiple returns submitted in your name. Or when you try to file your return online and the IRS rejects it mentioning that a tax return using your Social Security number has already been filed.

Tax Evasion


Tax evasion is when a person or business entity illegally avoids paying or underpays their tax liability. Tax evasion is a criminal charge subject to penalties. However, be careful not to confuse tax evasion with tax avoidance. Tax avoidance is a legal procedure that helps reduce taxpayer obligations.

IRS Impersonation Scam


Fraudsters may target American taxpayers and call them pretending to be IRS collection officers. Scammers lie to the taxpayer stating that they have many criminal charges and threaten them with arrests and frozen assets if they don’t pay a couple of thousand dollars immediately by providing gift card numbers and PIN. They also ask American taxpayers to provide them with their Social Security numbers.

To help people from being victims of such scams, the IRS has released a statement saying that the government doesn’t conduct or send unsolicited emails, text messages, or phone calls to discuss tax issues. Moreover, the IRS stated that it doesn’t use social media to get in contact with taxpayers.

IRS Fraud Reporting – How to Do it

Tax fraud happens when someone provides false tax information. When people and corporations don’t pay what they owe, the burden falls unfairly on everyone else. Before the government can prosecute anyone for tax fraud, it has to have proof. That’s often hard to obtain. That’s why the government relies on its citizens to help by reporting any known or suspected tax fraud.

Make Sure It’s Not a Hunch


Before reporting someone for tax fraud, make sure that what you’re feeling is also the reality. You don’t want to trouble someone and exhaust the government’s resources just because you are feeling a hunch.

Collect Evidence

The first step to report a suspected tax fraud is to gather as much evidence of the fraud as possible to help them catch the fraudster. Look for any evidence that will support your claims. Also, keep a copy of your proof for yourself.

Your evidence should include information on:

  • the person or the business involved in the crime
  • their address
  • the amount of money
  • the number of years they have been breaking the law

You have to write all the information down. Also, consider writing down the details of any action or events that led to your suspicions.

Write down your memories and observations with as many details as possible. Also, collect the names of other witnesses. They might have firsthand knowledge of the fraud. You can then give the IRS their names and contact information to acquire a more profound understanding of the case.

Don’t Break the Law Yourself


When gathering information about the crime, remember that opening someone else’s mail or logging on to their computers without their consent is considered stealing, and stealing is breaking the law. If you don’t have a specific document in your possession, you can inform the IRS where they can find it instead of breaking the law.

Report the Fraud

After you have gathered all the information to prove a tax fraud, it’s time to report it to the IRS. There are initially three ways to report fraud. You can call the IRS fraud line, send a letter, or use a fraud reporting form.

Most of the time, to report tax fraud, you need to present the following information:

  • The name of the individual or corporation suspected of the fraudulent activity
  • The number of years participating in criminal activities
  • The accused taxpayers’ identification number
  • The estimated amount of money involved
  • Information explaining how you learned of tax fraud

Keep in mind that when reporting tax fraud, you have the option to keep your information a secret. In case you want to disclose your name, the IRS will keep your information confidential.

If you want to remain anonymous, you can’t testify against the person should they be prosecuted.

Use the IRS Fraud Line

You can report tax fraud to the IRS over the phone by dialing the IRS fraud line 1-800-366-4484 (1-800-877-8339 for TTY/TDD users).

Send a Letter

If you prefer, you can write a letter to report activity and send it to the IRS Lead Development Center located at 24000 Avila Road, Laguna Niguel, California 92677-3405.

Use an IRS Fraud Reporting Form

If you know of a significant tax cheater, you should certainly consider filing an IRS whistleblower complaint. The IRS whistleblower program allows individuals to report tax fraud. In return, the IRS whistleblower office may offer a financial reward of up to 30% of the amount collected to the people who blow the whistle on those committing tax fraud. Keep in mind that if you want to claim a reward, you have to complete Form 211.
