IRS Private Debt Collectors Are Now Handling Smaller and Older Balances: How to Tell a Real Call from a Scam

The IRS significantly broadened its private debt collection program in 2026, assigning a larger volume of overdue tax accounts to outside firms. If you owe back taxes, even a relatively small or older balance, you may now hear from one of these collectors. The problem is that scammers are exploiting the confusion, and millions of taxpayers cannot tell who is actually calling.

What Changed in 2026

The Internal Revenue Service has significantly broadened its private debt collection program in 2026, assigning a larger volume of overdue tax accounts to third-party firms. While the program has existed since 2017 under the FAST Act, this year’s expansion marks its most aggressive phase, with broader eligibility criteria that now include smaller balances and older debts.

In plain terms: if you previously assumed your balance was too small or too old to attract attention, that assumption may no longer be safe. The IRS logged over 300,000 scam complaints related to tax collection in the most recent fiscal year, with losses in the hundreds of millions. The broader the program gets, the larger the pool of confused taxpayers that fraudsters can target.

For taxpayers already anxious about what they owe, the surge in collection calls has created a perfect storm of confusion, and scammers are taking full advantage.

How the Program Actually Works

Understanding the rules of the real program is the fastest way to spot a fake one.

Private collection agencies work on accounts where taxpayers owe money, but the IRS is not actively working them. Several factors contribute to the IRS assigning these accounts to private collection agencies, including older, overdue tax accounts or lack of resources preventing the IRS from working the cases.

A 2015 law establishing the program requires the IRS to contract with private collection agencies for certain tax debts, including those the IRS determined it lacked resources to pursue. The program was re-authorized under the Fixing America’s Surface Transportation Act, known as the FAST Act, and private collection activity began in April 2017. The 2026 expansion is the most significant broadening of the program since it launched.

Here is something important to understand about what these agencies can and cannot do: Private collection agencies cannot take any type of enforcement action against you to collect your debt. However, the IRS does have the legal authority to file a Notice of Federal Tax Lien or issue a levy to collect an overdue account. A private collector calling you is not the same thing as the IRS preparing to garnish your wages or seize your bank account. Only the IRS itself can do that.

The Two Letters That Prove a Call Is Legitimate

This is the single most reliable way to separate a real collector from a scammer. A legitimate private collection process always starts with written mail, never a surprise phone call.

The IRS will always send a written notice, Letter 5893, before any private collector makes contact, and the collector itself must send Letter 1544 before calling. Both letters will include details about your account and a unique taxpayer authentication number. There will be information in those letters that will help you verify that calls from a private collection agency are legitimate. Keep these letters. If anyone other than the agency listed in your letter calls you about your tax debt, it is a scam.

This two-letter sequence is not optional. The IRS does work with collection agencies under certain circumstances to help with the collection of unpaid taxes. Your first communication with the collection agency should not come out of nowhere. If a call arrives before any letters, hang up.

How to Verify a Caller Right Now

Even if you have received the letters, it pays to double-check before discussing your account or agreeing to any payment. Here is exactly what to do.

• Check the caller against the authorized list. Only four agencies are currently authorized: CBE Group, Coast Professional, ConServe, and Pioneer Credit Recovery. If the company calling you is not one of these four, it is a scam. Full stop.
• Call the IRS directly to confirm. Taxpayers can verify any assignment by calling the IRS at 800-829-1040. Do this before giving the caller any personal information.
• Match the authentication number. The collector should be able to tell you the code that appears on your notice. If not, do not talk with them. Do not rely on the caller ID to verify them, as that can be manipulated.
• Never pay the collector directly. Private collection agencies will not ask for payment on a prepaid debit, iTunes, or gift card. Taxpayers will be informed about electronic payment options at IRS.gov/pay. Payment by check should be payable to the U.S. Treasury and sent directly to the IRS, not the private collection agency.
• Expect a live person, not a recording. These debt collectors will never use robocalls or pre-recorded messages. You will always speak with a live operator.
• No in-person visits, no social media. Legitimate agencies will not ask for gift cards, threaten arrest, or message you on social media. They will never ask you for personal bank or financial information. Authorized collection agencies do not make in-person visits.

Red Flags That Tell You It Is a Scam

Scammers have gotten sophisticated. Some will use official-sounding language and may even know your name or address. Watch for these warning signs regardless of how polished the caller sounds.

• They demand payment immediately, in full, without giving you time to verify anything.
• The collector requests payment via cryptocurrency, wire transfer, iTunes gift cards, PayPal, Venmo, or other types of gift cards.
• They threaten arrest, deportation, police action, or license suspension. Debt collectors are not permitted to threaten you with criminal charges. There are only a few situations where a debt can lead to an arrest, and a real debt collector should not claim they can have you arrested.
• They cannot or will not provide the authentication number that matches the letter you received.
• The IRS and its collectors will never initiate contact via email, text, or social media. Any contact through those channels is fraudulent.

If you suspect you have already given personal or financial information to a fraudulent caller, contact the Treasury Inspector General for Tax Administration (TIGTA) and the Federal Trade Commission (FTC) right away. You may also want to place a fraud alert on your credit report.

You Have More Options Than You Think

Many people who get a collection call, real or fake, feel backed into a corner. They assume their only choice is to pay whatever is demanded. That is not true.

Many taxpayers assume that because the IRS is involved, they have no options. Private collectors cannot garnish wages, file liens, or seize assets. Only the IRS can. The collector’s job is to contact you and arrange payment. They do not set the terms of your overall situation with the IRS.

Depending on your circumstances, you may qualify for programs that address your tax debt in a more structured way, including installment agreements, an Offer in Compromise, or currently-not-collectible status. If you do not wish to work with your assigned private collection agency to settle your overdue tax account, you must submit this request in writing to the agency. Your account can be returned to the IRS, where a wider range of resolution options may be available to you.

The most important step right now is not to panic and not to pay anything before you have confirmed what you actually owe and what options exist. Delays add penalties, interest, and enforcement risk, so acting promptly matters. But acting informed matters even more.

At Clear Start Tax, we help individuals and businesses understand where they stand with the IRS, verify collection contacts, and explore every resolution option that may apply to their situation. If you have received a letter or a call and you are not sure what to do next, speaking with a tax resolution professional is the right move before making any decisions.
