The Top 5 Signs the IRS Is Investigating You

If you’ve ever wondered, “Is the IRS watching me?”—you might be right.

The IRS doesn’t always knock on your door with a badge and a briefcase. In fact, most IRS investigations start quietly, behind the scenes. And by the time you get an official notice, things are already serious.

At IRS Trouble Solvers, we specialize in identifying early warning signs so we can protect our clients before enforcement begins.

Here are the top 5 signs the IRS may be investigating you—and what to do about it.

1. You’ve Received a CP75, CP2000, or Other Suspicious IRS Letter

The most obvious red flag? A letter from the IRS suggesting your reported income doesn’t match their records—or that your return has been selected for additional review.

Common examples include:

• CP2000 – Underreported income
• CP75 – Request for audit documentation
• Letter 6323 – Information Document Request (IDR)

Don’t ignore these. These letters are often the first step in a much deeper investigation.

2. The IRS Is Contacting Your Employer or Clients

If the IRS reaches out to your employer, your customers, or your financial institutions, that’s a major sign they’re trying to verify income, assets, or behavior.

This can happen before they ever contact you directly—and is common in self-employed or high-income audits.

3. You’ve Deposited Large Sums of Cash or Reported Irregular Income

Frequent large deposits, inconsistent income, or a lifestyle that doesn’t match your tax returns are all red flags.

Examples include:

• Regular $10,000+ deposits
• Reporting minimal income while owning luxury items
• Undocumented foreign income

IRS investigators look for financial inconsistencies. If something doesn’t add up, they’ll investigate—quietly at first.

4. You’ve Been Audited Multiple Times or Amended Returns Repeatedly

Being audited once doesn’t always mean trouble. But if you’ve been audited multiple years in a row—or you’ve filed numerous amended returns—it may raise red flags.

The IRS may suspect:

• Fraudulent deductions
• Repeated underreporting
• Pattern behavior that warrants criminal review

If they suspect willfulness or deception, they may escalate from audit to investigation.

5. You’re Being Contacted by an IRS Criminal Investigator (CID)

The Criminal Investigation Division (CID) doesn’t get involved unless they suspect tax evasion, fraud, or other illegal activity.

If you’re contacted by an IRS special agent (not just a revenue officer), you are under investigation.

At this point, you need to speak to a tax attorney immediately—and avoid speaking to the IRS without professional representation.

What To Do If You Suspect an IRS Investigation

Do NOT ignore the signs.

Even if you’re unsure, early action can protect your finances, your business, and your reputation.

• Call a professional – At IRS Trouble Solvers, we know how to communicate with the IRS and build protective legal strategies.
• Don’t panic or lie – Remain calm. Saying the wrong thing can make things worse.
• Organize your documents – Tax returns, bank statements, W-2s, 1099s, and deduction records.
• Don’t delay – The sooner you act, the more options you have.

The IRS Plays the Long Game—So Should You

The IRS has years to investigate you. But you don’t have to wait until they strike. Getting ahead of the process is the key to reducing penalties, avoiding criminal charges, and protecting your assets.
