What Is a CP75 Notice and Why Does the IRS Send It?
Quick Answer: A CP75 notice is an IRS audit letter. It holds a client’s refund until they prove they qualify for the Earned Income Tax Credit, Child Tax Credit, or Head of Household status.
The IRS sends a CP75 when it questions a refundable credit. In most cases, the notice targets the Earned Income Tax Credit, or EITC. It may also question the Child Tax Credit and Head of Household filing status. As a result, the client’s refund stays frozen until they respond. Furthermore, the notice arrives with a strict deadline that you cannot ignore.
In 2026, refundable credit audits remain a top IRS focus. The Taxpayer Advocate has long warned that EITC audits hit low-income filers hardest. Therefore, tax pros should expect steady CP75 volume. Moreover, the 2026 Child Tax Credit sits at $2,200 per child under the One Big Beautiful Bill Act. Higher credits mean more IRS scrutiny.
Why the IRS Questions Refundable Credits
Refundable credits pay money even when a client owes no tax. Consequently, the IRS views them as fraud-prone. The agency uses computer filters to flag suspicious returns. For example, it flags mismatched addresses or duplicate child claims. In addition, it flags shared custody disputes between two parents.
What Happens If You Ignore a CP75
Ignoring the notice triggers full disallowance. As a result, the IRS denies the credit and keeps the refund. Worse, the client may face a two-year EITC ban. In some cases, the ban lasts ten years. Therefore, a proactive tax filing and compliance response protects your client’s money.
Pro Tip: Read the notice date carefully. The 30-day clock starts from that date, not the day it arrives.
What Are the CP75 Qualifying Child Documentation Requirements?
Quick Answer: CP75 qualifying child documentation requirements cover four core tests. You must prove relationship, age, residency, and joint return status for each child.
The IRS applies five tests to a qualifying child. However, a CP75 audit focuses on documents that prove those tests. First, you prove the relationship. Second, you prove the age. Third, you prove residency for more than half the year. Finally, you confirm the child did not file a joint return. You can review the full rules in the IRS EITC qualifying child guidance.
Proving the Relationship Test
The relationship test confirms how the child relates to the taxpayer. Common qualifying relationships include a son, daughter, grandchild, or sibling. To prove it, gather these documents:
- Birth certificate naming the taxpayer as parent
- Adoption decree or placement papers
- Court order for legal guardianship
- Records linking a grandchild or sibling
Proving the Residency Test
Residency is the hardest test to prove. The child must live with the taxpayer for more than half the year. Therefore, you need official records that show the same address. For example:
- School records showing home address
- Medical or clinic records with dates
- Daycare or childcare statements
- A letter from a landlord or clergy member
Did You Know? Records must cover the tax year, not the current date. Mismatched dates cause most CP75 denials.
Which IRS Forms Support a CP75 Response?
Quick Answer: Use Form 886-H-EIC for EITC, Form 886-H-DEP for dependents, and Form 886-H-HOH for Head of Household claims.
The IRS provides checklist forms that list every accepted document. These forms remove the guesswork. As a result, you send the exact proof the auditor wants. You can download Form 886-H-EIC directly from the IRS. Below is a quick comparison of the three main forms.
| IRS Form | Purpose | Best Used For |
|---|---|---|
| 886-H-EIC | EITC qualifying child proof | Refund frozen for EITC |
| 886-H-DEP | Dependent and CTC proof | Child Tax Credit claims |
| 886-H-HOH | Head of Household proof | Filing status disputes |
How to Use the 886-H Forms as a Checklist
Treat each form as your master checklist. First, read every line item. Next, match a document to each requirement. Then, label each document clearly. Finally, include the form itself in your response packet. This approach shows the auditor you covered every base.
Matching Documents to the 2026 Child Tax Credit
For 2026, the Child Tax Credit equals $2,200 per qualifying child. This figure rose under recent 2025 legislation and applies now. The child still needs a valid Social Security number by the due date. Therefore, confirm the SSN card matches the return. You can verify current rules on the IRS Child Tax Credit page. Verify current limits at IRS.gov before filing.
Pro Tip: Never send original documents. Instead, send clear copies and keep the originals safe.
How Do You Respond to a CP75 Notice Step by Step?
Quick Answer: Read the notice, gather documents, complete the matching 886-H form, and mail or fax your packet before the 30-day deadline.
A clean response process saves time and wins cases. Moreover, it protects you from missed deadlines. Follow this proven workflow for every CP75 client. In addition, build these steps into your firm’s business systems and automation so nothing slips.
The Five-Step CP75 Response Workflow
- Confirm the deadline from the notice date.
- Identify which credit or status is questioned.
- Gather documents using the correct 886-H form.
- Assemble a labeled, organized response packet.
- Send by certified mail or the listed fax number.
Tracking and Follow-Up
Always keep proof of delivery. Certified mail gives you a tracking number. As a result, you can prove the IRS received your response. After sending, wait about 30 days for a reply. Then, follow up if you hear nothing. The IRS lists CP75 notice instructions on its website. Meanwhile, keep your client calm and informed.
Pro Tip: Create a single PDF packet per child. Clear labels help auditors approve faster.
How Can Tax Pros Turn CP75 Defense Into Revenue?
Quick Answer: Package CP75 response as a paid audit-defense service. Charge a flat fee, systematize the workflow, and upsell year-round advisory.
Too many tax pros handle CP75 notices for free. However, this work carries real risk and takes real time. Therefore, you should price it as a professional service. In addition, a strong CP75 process builds trust that leads to bigger engagements. Many pros use these audits as a gateway to a full proactive tax strategy relationship.
Pricing Your CP75 Defense Service
Set a flat fee that reflects your value. For example, many firms charge $500 to $1,500 per CP75 case. The exact fee depends on the number of children and documents. Furthermore, offering a fixed price removes billing anxiety for the client. As a result, you get paid fairly and keep the relationship strong.
Scaling With the Right Tools
Audit defense pays the bills, but planning builds wealth. The biggest friction for growing firms is proving value before a client signs. That is why many pros now use tax planning software with unlimited assessments. You can run a free, client-ready assessment for every CP75 client. Then, you show them the savings a full plan unlocks. Consequently, a $700 audit fix becomes a $5,000 advisory engagement.

Frequently Asked Questions
How long do clients have to respond to a CP75?
Clients generally have 30 days from the notice date. Therefore, act fast. If you need more time, call the IRS number on the notice. In some cases, an agent will grant a short extension.
What if a client lost their documents?
You can request replacements. For example, schools and clinics keep records for years. In addition, a landlord letter can confirm residency. Therefore, missing paperwork rarely ends the case. Act early to gather substitutes.
Can two parents claim the same child?
No, only one taxpayer may claim a qualifying child. When both claim the child, the IRS applies tiebreaker rules. Generally, the parent with more nights wins. As a result, residency proof becomes vital.
Does a CP75 affect the 2026 Child Tax Credit?
Yes, a CP75 can freeze the Child Tax Credit portion of a refund. For 2026, that credit equals $2,200 per child. Therefore, proper documentation protects a large sum. Confirm the child’s SSN matches the return.
Should I charge clients for CP75 help?
Yes, CP75 defense is skilled work with real risk. Therefore, charge a fair flat fee. Moreover, this positions you as a trusted advisor. You can then upsell year-round planning and grow revenue.
