What Is a CP40 Notice?
A CP40 is a notice from the Internal Revenue Service informing you that your unpaid federal tax account has been assigned to one of the private collection agencies authorized under the IRS Private Debt Collection (PDC) program. The IRS is not pursuing your account directly any longer — a private company authorized by the IRS is now responsible for making collection contact on the IRS behalf.
The notice arrives on official IRS letterhead — not on the collection agency letterhead — and is sent by the IRS, not by the agency. It will include your name, address, Social Security number, the specific tax years and balances that have been referred, the name of the private collection agency assigned to your account, and the agency contact information.
The CP40 arrives before the collection agency makes contact with you. The IRS sends it specifically so you can verify that any subsequent calls or payment requests are legitimate rather than a scam. The private debt collection program is heavily impersonated by fraudsters, and the CP40 is your primary protection against being deceived.
Why Did You Receive a CP40?
The IRS does not assign every unpaid account to private collectors. The program is reserved for accounts that have been removed from active IRS collection inventory — accounts the IRS has determined are lower priority given its current staffing and resources.
Age of the debt. Accounts with balances outstanding for an extended period without active collection are more likely to be referred. The IRS prioritizes newer, larger, or more complex accounts for its internal collectors.
Account status. Accounts where the standard notice sequence has run without resolution and no active enforcement action is in progress are candidates for referral.
Account size and complexity. The IRS internal revenue officers focus on larger balances and complex enforcement situations. Smaller, older balances that would not justify intensive field collection effort are more likely to be routed through the PDC program.
Contact failures. If the IRS has been unable to establish contact with a taxpayer through standard mail notices — often because of address changes — the PCA may have better success making direct contact.
Receiving a CP40 does not mean your situation has become more or less serious. Your balance is unchanged. Your rights are unchanged. The enforcement authorities that apply to your account are unchanged. The only thing that has changed is which entity is making collection contact.
What Is Physically on the CP40?
The assigned agency name. There are currently four IRS-authorized private collection agencies. Your notice will identify which one has been assigned to your account. Write down this name — you will use it to verify any subsequent contact.
The agency contact information. Phone number, mailing address, and in some cases a website.
The tax years and amounts referred. The specific tax periods and dollar amounts that have been sent to the PCA. Note that the amounts shown include accrued interest and penalties through the referral date.
Your taxpayer rights. A summary of your rights when dealing with a private collection agency, including the right to have the account returned to the IRS.
IRS verification contact information. A number to call the IRS directly if you want to verify the assignment or have questions the agency cannot answer.
The Scam Risk Is Real — How to Protect Yourself
IRS impersonation scams are among the most prevalent financial fraud types in the United States, and the Private Debt Collection program is a particularly effective impersonation target. Legitimate private collection agencies working for the IRS will identify themselves as working on behalf of the IRS — not as the IRS itself. They will send written communication before or alongside phone contact. They accept payment only through established IRS payment methods — IRS.gov, checks payable to the U.S. Treasury, or IRS Direct Pay. They never request payment via wire transfer, gift cards, cryptocurrency, or prepaid debit cards.
If you receive a call that does not match these characteristics — or if you receive a call about PCA assignment before your CP40 arrives in the mail — treat it as a potential scam. Hang up and call the IRS directly at 800-829-1040 to verify your account status before taking any action.
What Rights Do You Retain After CP40?
Your rights as a taxpayer are fully preserved when your account is assigned to a PCA. The private collection agency has no additional powers that the IRS itself does not have, and it lacks several powers the IRS does have.
What the PCA can do: make contact by phone and mail, facilitate payment arrangements through IRS-approved channels, and accept payments on the IRS behalf.
What the PCA cannot do: garnish your wages, levy your bank account, file a Notice of Federal Tax Lien, seize physical assets, or take any enforcement action. All enforcement authority remains with the IRS itself.
You retain the right to request at any time that your account be returned from the PCA to the IRS for direct handling. You retain the right to apply for an Offer in Compromise, request Currently Not Collectible status, set up an installment agreement, request penalty abatement, or dispute the underlying balance — all handled through the IRS, not the PCA.
Where the CP40 Fits in the Collection Sequence
The CP40 does not fit neatly within the standard IRS notice escalation sequence of CP14 → CP501 → CP503 → CP504 → LT11. Rather than being a step in that linear sequence, it represents a parallel track — the IRS decision to route your account through the PDC program instead of pursuing it internally.
If the PCA is unable to successfully resolve your account, the IRS can recall the account from the PCA and resume internal collection at any point. An account recalled from PCA without resolution is not reset to square one — the IRS can proceed directly to levy notices if the earlier sequence has already been exhausted.
Who Receives CP40 Most Often?
Taxpayers with older unpaid balances are the primary candidates for PCA referral. Taxpayers who did not respond to the standard notice sequence — CP14 through CP504 — without responding or paying. Taxpayers with smaller balances that do not justify field enforcement effort. And taxpayers who moved without updating the IRS, causing the standard notice sequence to be mailed to an old address without the taxpayer's knowledge.

Frequently Asked Questions
Can I request that my account be returned to the IRS from the PCA?
Yes. You can request account return at any time by calling the IRS directly or by having a tax professional with a Power of Attorney make the request. This does not resolve the underlying debt, but it allows you to deal directly with the IRS rather than with the PCA.
Does CP40 change the amount I owe?
No. The CP40 does not add to or change your balance. The PCA collects on behalf of the IRS — the underlying debt, accrued penalties, and interest remain exactly as they were before the referral.
Will the PCA report my debt to credit bureaus?
PCAs working for the IRS generally do not report tax debts to consumer credit bureaus. However, if the IRS previously filed a Notice of Federal Tax Lien on your account, that lien is a public record that can appear in credit reporting.
Can the PCA negotiate a settlement for less than I owe?
No. PCAs cannot offer or approve Offers in Compromise, penalty abatement, or other settlement programs. Those programs require working directly with the IRS.
What if I believe I have already paid this balance?
Gather your payment records — bank statements, canceled checks, IRS payment confirmation numbers — and contact the IRS directly to have the payment verified and the account status corrected. Do not make a duplicate payment before confirming.
