IRS Notice CP75 Explained | What It Means and What Happens Next

Sorting through a stack of IRS mail can be disorienting, and CP75 is one of those notices that tends to raise more questions than it answers on a first read.

The IRS sends CP75 when it needs to verify that a taxpayer qualifies for one or more credits claimed on a return, most commonly the Earned Income Tax Credit. The notice places a hold on the related portion of any refund while the review is underway, which means the money is not lost, but it is not on its way either. Understanding what the IRS is actually asking for, and how the process works, makes it easier to respond clearly and avoid unnecessary delays.

What Is a CP75 and Why Did You Receive It

In plain terms, CP75 is an audit notice, though a narrow one. The IRS is not questioning your entire return. Instead, it has flagged specific credits for verification, typically the Earned Income Tax Credit, but sometimes also the Child Tax Credit, the American Opportunity Credit, or the Head of Household filing status. The notice is generated when the IRS computer system identifies information on the return that warrants a closer look before releasing a refund tied to those credits.

Common triggers include a change in the number of qualifying children listed, income figures that fall at or near the thresholds for EITC eligibility, a recently changed filing status, or a return that differs in some notable way from prior years. The IRS is not making an accusation. It is asking for documentation to confirm what was reported.

What the Notice Is Asking For

CP75 includes a response deadline, typically 30 days from the date printed on the notice, and a list of documents the IRS wants to see. The specific items vary depending on which credits are under review, but common requests include:

• Birth certificates or adoption papers for any qualifying children
• School records, medical records, or childcare provider statements showing the child lived with you
• Proof of your own identity and Social Security number
• Documentation of your earned income, such as W-2s, 1099s, or records of self-employment income
• Lease agreements, utility bills, or similar records confirming your home address during the tax year

The notice will name a specific IRS employee or unit to contact and provide a fax number or mailing address for sending documents. Reading through the full notice carefully before gathering anything is worth the time, since sending irrelevant documents can slow the process and omitting a requested item will likely extend the review.

The Refund Hold

When CP75 is issued, the IRS places a hold on the portion of the refund connected to the credits being reviewed. If your refund includes amounts unrelated to those credits, the IRS may release that portion while the review continues. The held amount remains pending until the review is resolved.

This is not a seizure or a penalty. It is a standard procedural hold. If the IRS confirms the credits are valid, the held refund is released, sometimes with interest if the delay has been substantial. If the IRS determines the credits were not fully supported, it will adjust the refund amount and send a separate notice explaining the change.

How Long the Process Typically Takes

After documentation is submitted, the IRS generally takes several weeks to process and review what was sent. The timeframe varies depending on the complexity of the case and current IRS workload, but reviews often take anywhere from six to twelve weeks or more. Submitting documents by fax rather than mail tends to result in faster processing, and including a copy of the CP75 notice with any submission helps the IRS route the response correctly.

If the deadline passes without a response, the IRS will generally deny the credits being reviewed and send a follow-up notice explaining the adjustment. At that point, options for challenging the decision still exist, but the process becomes more involved.

Responding to the Notice

Handling CP75 does not require a tax professional. Many taxpayers manage the documentation request on their own, particularly when the supporting records are straightforward and already on hand. The key steps are responding within the timeframe listed on the notice and keeping copies of everything submitted, including a fax confirmation or a certified mail receipt if sending by post.

For situations where the documentation is more complicated, such as shared custody arrangements, self-employment income with variable records, or a change in living situation during the tax year, working with a tax professional or an enrolled agent may help organize and present the information clearly. Low Income Taxpayer Clinics, which operate in most states and provide free or reduced-cost assistance, are one option for taxpayers who need guidance but have limited resources.

If the IRS Denies the Credits

A denial does not end the process. Taxpayers have the right to appeal an IRS decision, and if additional documentation exists that was not included in the original response, there is typically an opportunity to present it. The notice that follows a denial will explain the specific reason for the adjustment and outline the options available, including how to request a conference with the IRS Office of Appeals.

One consequence worth understanding is the EITC ban period. If the IRS determines that a credit was claimed due to reckless or intentional disregard of the rules, it can prohibit the taxpayer from claiming EITC for two years. For cases involving fraud, that ban extends to ten years. These outcomes are relatively uncommon and generally apply to more serious situations rather than routine documentation disputes, but they are part of the picture.

Common Questions at This Stage

People sometimes wonder whether CP75 affects their credit score or triggers any kind of collection action. It does not. This notice is part of the refund review process, not the collections process, and it has no direct effect on credit reporting.

Another question that comes up is whether filing an amended return in response to CP75 helps. In most cases it does not, and the IRS may ask that any amendments be held until the current review is complete. The focus at this stage is on supporting the original return, not revising it.

If the 30-day deadline is approaching and the documents are not yet ready, contacting the IRS using the number on the notice to request additional time is a reasonable step. Extensions are not guaranteed, but they are sometimes granted when there is a clear reason for the delay.
