Does the IRS call people about money they owe?

Sometimes. The IRS says it or a private collection agency may call about account matters, usually after letters. It never calls to demand payment now, threaten arrest or announce a refund. If a call worries you, hang up and call the IRS back on a number from IRS.gov.

Is a private debt collector for the IRS legitimate?

It can be. CBE Group, Coast Professional and ConServe collect certain overdue accounts for the IRS. You should first get Notice CP40 from the IRS and then a letter from the agency, both with the same taxpayer authentication number. A real agency never asks you to pay it directly or with gift cards.

Who do I make a payment to so it reaches the IRS?

Only the U.S. Treasury. Pay online through IRS.gov/payments, through your Online Account or EFTPS, or by check or money order payable to "U.S. Treasury". Anyone asking you to pay them, a gift card or a crypto wallet is not the IRS.

What should I do if I paid an IRS scammer?

Stop contact, call your bank or card issuer right away, and report it to TIGTA at 800-366-4484 or tigta.gov. If your personal information was taken, report it at IdentityTheft.gov and consider an IRS Identity Protection PIN. The Taxpayer Advocate Service can help for free.

Fake IRS Letter? How to Tell If an IRS Notice Is Real

Last reviewed October 2026Reviewed by Safwan Al-Sayyad, Global Gate Tax and Accounting

Short answer

A real IRS letter has a CP or LTR notice number you can look up on IRS.gov, matches the balance in your IRS Online Account, and asks you to pay only the U.S. Treasury. The IRS usually contacts you first by mail. It never demands immediate payment by gift card or wire, or threatens arrest.

Key takeaways

The IRS normally makes first contact by mail; it emails or texts only if you opted in and never sends social media direct messages.
Check any letter yourself: look up its CP or LTR number on IRS.gov, compare it with your Online Account, and call a number you found on IRS.gov.
Every payment goes to the U.S. Treasury through IRS.gov or a check; no real IRS contact asks for gift cards, wire transfers or crypto.
Private collection agencies are real, but they write before calling, and their letters share an authentication number with the IRS’s Notice CP40.
Report fake emails and texts to phishing@irs.gov and fake calls to TIGTA at 800-366-4484.

How the IRS really contacts you

The IRS says it normally contacts you the first time by letter, delivered by the U.S. Postal Service. A phone call, email or text about a tax bill you have never heard of is the biggest warning sign there is. Here is how each channel works, according to the IRS page How to know it’s the IRS (reviewed 22 October 2026).

Channel	What the real IRS does	What should make you suspicious
Mail	Its usual first contact. Some letters come from private collection agencies working for the IRS.	A letter number you can’t find on IRS.gov, or a letter sending you to a website or phone number that isn’t the IRS.
Phone	The IRS or a private collection agency may call about account matters. Automated messages send you to IRS.gov and don’t share account details.	Demands to pay now, threats of arrest, or news of a refund. The IRS says it never calls to do any of these.
Email	Only if you opted in. Account emails come from addresses ending in irs.gov.	Any unexpected email about a bill, refund or “account problem”.
Text message	Only if you opted in, from specific IRS short codes.	Any unexpected text with a link.
Social media	Never sends direct messages.	Every direct message that claims to be the IRS.
In-person visit	Rare, and usually after a letter. Revenue officers and agents carry a pocket commission and an HSPD-12 card, both with a photo and serial number.	A visitor who won’t show both IDs or asks for payment to anyone other than the U.S. Treasury.

So a phone call is not automatically fake. The test is whether it fits a paper trail: a real collection call follows letters you can check, and it never comes with threats or a demand for a gift card. The Federal Trade Commission adds that caller ID can be faked, so a number that looks official proves nothing.

Warning signs of a fake IRS letter, call or message

The IRS lists the signs that a contact is not from it. A call, email or text is likely a scam if it is unexpected, rushes you, threatens you, asks for personal or financial information, or demands payment now. Scams also tend to share these features:

Threats. Impersonators threaten arrest or deportation and don’t let you question or appeal the amount. A real notice explains how to dispute it.
Unusual payment methods. The FTC says the IRS and its debt collectors won’t demand that you wire money or pay with gift cards, cryptocurrency or a payment app.
Odd links and QR codes. Misspelled web addresses, or a QR code that leads to a site that only looks like IRS.gov.
A bill or refund out of nowhere. The IRS warns about fake “unexpected tax bill” and unclaimed-refund mailings.
Relief offers. Callers or mailers that promise to settle your balance for “pennies on the dollar” and rush you to pay a fee.

A current example: the IRS says fraudsters are mailing fake IRS letters to people who hold cryptocurrency. The letters send readers, including by QR code, to a fake site to register for a “Digital Asset Compliance Portal”. The IRS says it did not send them and runs no such portal.

Myth: A real IRS letter would never threaten to take your property.

Fact: Real final notices, such as the LT11 notice of intent to levy, do warn about levies on wages and bank accounts. What they don’t do is demand instant payment by phone or threaten arrest. They also give you a deadline and appeal rights.

How to check whether an IRS letter is real

Checking takes about 15 minutes, and none of it requires the phone number, website or QR code printed on the letter you doubt.

Find the notice number. Real IRS notices carry a CP or LTR number, which the IRS says you can find in the right corner of the letter. Search that number on the IRS notices and letters page. Our CP14 and LT11 guides show two common ones.
Compare it with your IRS Online Account. Sign in by typing irs.gov into your browser and opening your Online Account. It shows your balance by tax year, and you can view certain notices there. A bill that isn’t reflected in your account deserves a call.
Call a number you looked up yourself. If the letter doesn’t appear in the IRS search or looks suspicious, the IRS says to call 800-829-1040 (IRS.gov, 2026). Businesses can use 800-829-4933 (IRS.gov, 2026).
Pay only the U.S. Treasury. Pay through IRS.gov/payments (Direct Pay, your Online Account, EFTPS, or a card through an IRS-listed processor). By mail, make the check or money order payable to “U.S. Treasury”, never to a person or company.
Keep the letter. If it’s real, its deadline matters. If it’s fake, you will need it to report the scam.

If the letter checks out, it is a real notice and the clock on it is running. Our guide on how to respond to an IRS notice covers the next steps. Letters sent by certified mail are usually the more serious ones; see certified mail from the IRS.

Private collection agencies are real: how to check one

One genuine contact surprises many people: a private company collecting for the IRS. The law requires the IRS to assign certain overdue, inactive tax accounts to private collection agencies. Since 23 September 2021, three agencies have held the contracts, according to the IRS private debt collection page (reviewed 21 August 2026):

CBE Group, Waterloo, Iowa: 800-910-5837
Coast Professional, Geneseo, New York: 888-928-0510
ConServe, Fairport, New York: 844-853-4875

How a real assignment works. You get two letters before any call. First the IRS sends Notice CP40 saying your account was assigned. Then the agency sends its own letter. Both carry the same taxpayer authentication number, which you and the agency use to confirm each other’s identity. The agency should not call before its letter arrives. You can also check your account transcript, which shows transaction code 971 when an account is referred to a private agency (see reading your account transcript).

What a real agency will not do, according to the IRS FAQs:

ask you to pay the agency directly, or by prepaid debit card or gift card (all payments go to the IRS; checks are payable to the United States Treasury);
take enforcement action, such as a levy or a Notice of Federal Tax Lien (only the IRS can);
collect financial information, accept or reject an offer in compromise, or charge a fee to set up a payment arrangement.

If you would rather not work with the agency, you must say so in writing to the agency. The IRS also says it does not assign certain accounts to these agencies, including those with a pending offer in compromise or an installment agreement, under examination or levy, or of taxpayers whose income is at or below 200% of the poverty level.

Where to report a fake IRS contact

These are the reporting routes the IRS lists on its report phishing page (reviewed 30 July 2026):

What you received	Where to report it
Email	Don’t click or reply. Send it to phishing@irs.gov as an attachment (subject “IRS”), then delete it. You can also report it to TIGTA and the FTC.
Text message	Send the sender’s number, the text, and the date and time to phishing@irs.gov (subject “Text”). Forward the text to 7726 (SPAM).
Phone call	Record the number and hang up. Report it to the TIGTA hotline at 800-366-4484 or through tigta.gov.
Social media account or message	Report it to the platform and send the account’s full web address to phishing@irs.gov (subject “Social media”).
Letter	Report fake letters about refunds, liens or tax relief to the U.S. Postal Service, the FTC, or your state attorney general’s consumer protection office.
Private collection agency misconduct	TIGTA (hotline or tigta.gov).
Tax relief sales calls	The FTC at ReportFraud.ftc.gov and the Federal Communications Commission.

TIGTA, the Treasury Inspector General for Tax Administration, is the independent watchdog that investigates IRS impersonation. Its mailing address is TIGTA Hotline Team, P.O. Box 23291, Washington, D.C. 20024.

If you already paid or shared information

Stop contact with the scammer and call your bank or card issuer right away. The IRS also suggests reporting stolen personal information through the FTC’s IdentityTheft.gov site, getting an Identity Protection PIN, and filing Form 14039 if someone used your Social Security number to file a return. The Taxpayer Advocate Service helps scam victims for free. Be wary of anyone who then offers to recover your money for a fee; the IRS warns that some victims get scammed twice.

If the letter is real: your next step

Finding out the notice is genuine is not good news, but it is useful. A real notice comes with a deadline and options. Which page to read next depends on the letter:

A second kind of scam targets people who really do owe: companies that promise to wipe out a balance for a large upfront fee. The IRS says you can apply for an offer in compromise directly if you qualify. Our guide to spotting a tax relief scam lists the warning signs. Free, honest help is available from the Taxpayer Advocate Service and Low Income Taxpayer Clinics.

Frequently asked questions

Look for a CP or LTR notice number and search it on IRS.gov, then check that your IRS Online Account shows the same balance. If the letter can’t be found or still looks wrong, call the IRS at 800-829-1040 using that number, not one printed on the letter.
