What Is a CP75 Notice and Why Are Clients Receiving Them?

The CP75 EITC examination notice CPA guide starts with understanding what triggers these notices. The IRS issues CP75 letters when its automated compliance systems identify returns claiming EITC that fall outside normal parameters. For the 2026 tax year, the IRS significantly increased automation to compensate for the 27% workforce reduction. However, this created a bottleneck for returns requiring human review.

National Taxpayer Advocate Erin Collins reported that taxpayers whose returns required manual intervention often struggled to get assistance. Phone answer rates dropped to just 34% for compliance lines and 19% for identity theft inquiries. This makes professional tax advisory services critical for clients facing CP75 examinations.

Why the IRS Targets EITC Claims

The Earned Income Tax Credit remains one of the largest refundable credits in the tax code. As a result, it faces heightened IRS scrutiny. The agency uses predictive analytics to identify returns with characteristics associated with improper EITC claims.

Common triggers include discrepancies between Schedule C income and third-party reporting, qualifying child claims that conflict with custodial arrangements, and income levels that fall suspiciously close to EITC phase-out thresholds. According to IRS due diligence requirements, tax preparers must verify eligibility criteria before claiming EITC.

The 2026 Examination Environment

The 2026 filing season created unprecedented challenges. With IRS staffing down to 74,000 employees, the agency relied heavily on technology improvements and automation. However, CP75 examinations require manual case review that automation cannot fully replace.

Tax professionals report case resolution times averaging 20 months for complex manual reviews. This extended timeline affects clients’ financial planning and creates significant uncertainty. Understanding how to navigate this environment efficiently is essential for maintaining client relationships and ensuring proper credit claims.

How Should CPAs Respond to a CP75 Examination Notice?

The CP75 notice includes a specific response deadline, typically 30 days from the notice date. Missing this deadline can result in automatic EITC disallowance and significant refund delays. Tax professionals must establish a systematic response protocol for these notices.

Step-by-Step Response Protocol

Your response strategy should follow these critical steps:

• Review the CP75 notice immediately to identify which EITC requirements the IRS questions
• Contact the client within 48 hours to explain the situation and gather documentation
• Verify your Power of Attorney authorization is on file with the IRS using Form 2848
• Compile all required documentation addressing the specific questions raised in the notice
• Prepare a comprehensive written response with a detailed explanation of EITC eligibility
• Submit response via certified mail with return receipt at least 5 days before the deadline
• Document all communication attempts and maintain copies of all submissions

According to the National Taxpayer Advocate, taxpayers facing manual review processes struggled significantly in 2026. Professional representation dramatically improves outcomes in these examinations.

Communication Strategies When Phone Support Fails

With only 34% of compliance calls answered in 2026, tax professionals cannot rely on phone contact. Instead, use written correspondence exclusively. This creates a permanent record and ensures your response meets the deadline requirements.

The IRS Form 4442 referral system for taxpayer inquiries experienced significant delays in 2026. Treasury Inspector General audits found that 33% of referrals lacked proper documentation, and 8% missed required closing codes. This makes direct written response to the examination unit critical rather than attempting to route inquiries through customer service.

Setting Client Expectations

Transparency about timelines protects the client relationship. Explain that manual review cases averaged 20 months for resolution in 2026. Identity theft cases faced even longer delays, approaching 600 days. Your role includes managing client anxiety throughout this extended process while maintaining diligent follow-up with the IRS.

What Documentation Does the IRS Require for CP75 Responses?

Documentation requirements for CP75 responses follow specific IRS guidelines. The examination focuses on three primary EITC criteria: qualifying child status, residency requirements, and income accuracy. Each requires distinct documentation.

For 2026 tax year examinations, use the CP75 Notice Response Tool to organize documentation and track submission requirements systematically.

Qualifying Child Relationship Documentation

The IRS requires proof of the biological, step, foster, or adoptive relationship to the qualifying child. Acceptable documentation includes:

• Birth certificates showing the taxpayer as parent
• Court orders establishing custody or guardianship
• Adoption papers with finalization dates
• Foster care placement documentation from authorized agencies
• School records listing the taxpayer as parent or guardian

Residency Proof Requirements

The qualifying child must live with the taxpayer for more than half the year. The IRS accepts various forms of proof across different months. Effective documentation includes:

• School records showing the taxpayer’s address and enrollment dates
• Medical records with the child’s name and the taxpayer’s address
• Childcare provider statements with attendance dates and locations
• Religious organization records showing participation throughout the year
• Landlord statements confirming the child lived at the residence
• Social services records documenting the living arrangement

The more documentation spanning different months, the stronger your case. A single document type is rarely sufficient. The IRS specifically looks for contemporaneous records created throughout the year, not documents prepared after the CP75 notice.

Income Verification Materials

For self-employed clients, income documentation requires particular attention. The IRS often questions Schedule C income that appears strategically positioned within EITC income ranges. Provide comprehensive business records including:

• Bank statements showing business deposits throughout the year
• Form 1099-NEC or 1099-K statements from all clients or platforms
• Business expense receipts supporting Schedule C deductions
• Mileage logs for transportation expenses
• Contracts or invoices demonstrating legitimate business activity

Documentation Quality Standards

The IRS requires clear, legible copies of all documentation. Organize materials chronologically with a cover letter explaining each document’s relevance to EITC eligibility. According to IRS guidance on CP75 notices, poor documentation quality frequently leads to requests for additional information, extending case resolution times.

EITC Requirement	Primary Documentation	Supporting Evidence
Qualifying Child Relationship	Birth certificate, adoption decree	School records, medical records
Residency (6+ months)	School enrollment records	Medical records, childcare statements
Income Accuracy	Form 1099s, W-2s, bank statements	Business records, expense receipts
Age Requirement	Birth certificate	School enrollment (if student)

What Are Common EITC Disqualification Triggers?

Understanding what prompts CP75 notices helps tax professionals implement preventive measures. The IRS uses sophisticated matching algorithms that compare return data against multiple databases. Certain patterns consistently trigger manual examinations.

Duplicate Qualifying Child Claims

When multiple taxpayers claim the same child, the IRS immediately flags all returns. This frequently occurs in separated or divorced families where custody arrangements are unclear. Even when parents alternate years claiming the child, poor documentation creates problems.

The tie-breaker rules under IRS regulations determine which taxpayer has priority. However, the IRS requires both taxpayers to prove their case independently. Professional self-employed tax services become critical when navigating these complex family situations.

Strategic Income Positioning

The IRS scrutinizes returns where reported income falls precisely within optimal EITC ranges. For 2026, verify current EITC income limits and phase-out ranges at IRS.gov, as these amounts adjust annually for inflation. Returns showing income that maximizes the credit while minimizing tax liability attract examination.

Self-employed individuals face particular scrutiny when Schedule C net profit falls within EITC sweet spots. The IRS expects consistency between reported income and business activity indicators like home office deductions, vehicle expenses, and equipment purchases.

Address and Residency Inconsistencies

The IRS cross-references the address on the tax return with school district records, prior year returns, and other government databases. Inconsistencies trigger CP75 notices. Changes in address during the tax year require clear documentation of the qualifying child’s location throughout the full year.

Taxpayers claiming children who attend school in a different district than the return address face enhanced scrutiny. Grandparents raising grandchildren often encounter these issues when the child’s parents maintain official custody but the child lives primarily with the grandparent.

Missing or Incomplete Social Security Numbers

Every qualifying child must have a valid Social Security Number issued before the return due date. Individual Taxpayer Identification Numbers do not qualify. Late SSN issuance or typographical errors in the SSN field generate automatic CP75 notices.

Red Flag	IRS Concern	Prevention Strategy
Child claimed by multiple taxpayers	Conflicting claims	Review prior year returns for all parties
Schedule C income at optimal EITC level	Income manipulation	Document legitimate business records contemporaneously
Child’s school different from return address	Residency question	Obtain written residency confirmation from school
New qualifying child not claimed previously	Relationship verification	Attach Form 8862 and relationship documentation

How Do You Prevent Future CP75 Notices for Clients?

 

 

Prevention requires systematic EITC due diligence procedures. Tax professionals who implement robust verification processes substantially reduce CP75 notice frequency for their client base. This protects both client outcomes and your professional reputation.

Form 8867 Due Diligence Checklist

Form 8867, Paid Preparer’s Due Diligence Checklist, is mandatory for all paid preparers claiming EITC, Child Tax Credit, American Opportunity Tax Credit, or Head of Household status. Failure to comply results in preparer penalties. The form requires you to document specific steps taken to verify eligibility.

Your due diligence must include asking appropriate questions to determine eligibility, documenting the questions and client responses, verifying information provided by the client, and reviewing prior year returns for consistency. According to IRS regulations, you cannot simply rely on client statements when information appears incorrect or incomplete.

Knowledge Inquiry Documentation

Circular 230 requires practitioners to make reasonable inquiries if information provided appears incorrect, inconsistent, or incomplete. Document your inquiry process thoroughly. When a client claims a child, your file should show:

• Questions asked about the child’s relationship to the taxpayer
• Verification that the child lived with the taxpayer for over half the year
• Confirmation that no other taxpayer will claim the child
• Review of custody arrangements for separated or divorced parents
• Discussion of tie-breaker rules when applicable

Many firms use engagement letters that specifically address EITC due diligence requirements and client responsibilities. This creates a clear record of your professional standards and the client’s acknowledgment of accurate information requirements.

Client Education Programs

Proactive client education reduces documentation problems. Provide clients with a year-end checklist of records to maintain for EITC substantiation. This includes school records, medical records, and childcare documentation that accumulates naturally throughout the year.

Successful firms send quarterly reminders to EITC-eligible clients about documentation requirements. This positions you as a trusted business tax advisor rather than just a return preparer, while simultaneously building the documentation foundation needed if CP75 notices arrive.

Consistency Reviews

Compare the current year return to prior years for consistency in qualifying child claims, filing status, and income patterns. Unexplained changes should trigger additional inquiry and documentation. The IRS uses multi-year analysis in its examination selection, so you should too.

For self-employed clients, review whether Schedule C profit margins remain consistent with the industry and prior years. Significant deviations require business record substantiation before filing.

What Are Circular 230 Compliance Requirements for EITC Due Diligence?

Circular 230 establishes the professional conduct standards for tax practitioners. These regulations directly impact how CPAs handle EITC claims and respond to CP75 notices. Understanding these requirements protects your practice from preparer penalties and disciplinary action.

Section 10.22 Diligence Requirements

Section 10.22 requires practitioners to exercise due diligence in preparing or assisting in the preparation of returns and determining the correctness of representations made to the IRS. For EITC claims, this means you cannot simply accept client information at face value when it appears questionable.

The standard is reasonableness under the circumstances. You must make inquiries consistent with professional judgment. According to recent IRS guidance on professional standards, this includes understanding the operational mechanics and limitations of any technology tools used in tax practice.

Section 10.37 Written Advice Standards

When providing written advice on EITC matters, Section 10.37 requires you to base advice on reasonable factual and legal assumptions, consider all relevant facts, and relate applicable law to those facts. Email correspondence about CP75 responses constitutes written advice under these rules.

You cannot rely on client representations if reliance would be unreasonable. This particularly applies to residency claims and income reporting where objective verification is readily available. Your professional competence includes understanding EITC eligibility rules thoroughly.

Section 10.36 Procedures for Tax Practice

Section 10.36 requires firms to establish procedures to ensure compliance with Circular 230. This includes implementing quality control measures, training staff on due diligence requirements, and maintaining adequate documentation systems.

For EITC practices, your procedures should include standardized client questionnaires, document collection protocols, second-level review for returns claiming EITC, and regular staff training on evolving compliance requirements. Maintaining these procedures demonstrates reasonable care if examined.

Preparer Penalty Exposure

IRC Section 6695(g) imposes penalties for failure to comply with EITC due diligence requirements. The penalty is per failure, meaning multiple inadequate returns result in multiple penalties. For 2026, penalties have increased with inflation adjustments. Verify current penalty amounts at IRS.gov.

Beyond monetary penalties, repeated violations can result in suspension or disbarment from practice before the IRS. The Office of Professional Responsibility actively investigates preparers with patterns of improper EITC claims.

Circular 230 Section	Requirement	CP75 Application
Section 10.22	Exercise due diligence	Verify EITC eligibility before filing
Section 10.35	Competence requirement	Understand EITC rules and examination procedures
Section 10.36	Firm procedures	Implement systematic EITC verification protocols
Section 10.37	Written advice standards	Base CP75 response on verified facts and law

Uncle Kam in Action: CPA Firm Resolves Multi-Client CP75 Crisis

A mid-sized CPA firm in the Midwest faced a significant challenge in early 2026. Fifteen of their clients received CP75 notices within a two-week period, all questioning EITC claims on 2025 tax returns. The firm had prepared these returns following their standard procedures, but the automated IRS systems flagged multiple returns for manual examination.

The clients represented diverse situations. Several were self-employed contractors with fluctuating income. Others were separated parents with informal custody arrangements. Two clients had moved during the tax year, creating address inconsistencies with school records. The firm faced potential preparer penalties if they could not demonstrate adequate due diligence.

The managing partner recognized the scale of the problem required systematic intervention. The firm implemented Uncle Kam’s tax strategy platform to organize their response. They began by conducting a comprehensive audit of their EITC documentation procedures.

For each client, they assembled complete documentation packages within ten days of notice receipt. This included birth certificates, school records covering seven months, medical records, and childcare provider statements. For self-employed clients, they compiled bank statements, 1099 forms, and business expense documentation that substantiated reported income.

The firm prepared detailed written responses for each examination. They submitted all responses via certified mail three weeks before the deadline. They also implemented new procedures including quarterly client documentation reminders, enhanced Form 8867 processes, and second-partner review for all EITC returns.

The results exceeded expectations. Within four months, the IRS accepted thirteen of fifteen EITC claims without additional inquiry. The two remaining cases required supplemental documentation but were ultimately approved. The firm’s clients received full refunds including the EITC amounts.

The firm avoided all preparer penalties by demonstrating their systematic due diligence procedures. Their investment in proper response protocols and documentation systems resulted in zero EITC claim denials. Client satisfaction increased as the firm positioned itself as an expert resource for navigating IRS examinations rather than just a return preparation service.

Frequently Asked Questions

What happens if a client misses the CP75 response deadline?

Missing the CP75 deadline typically results in automatic EITC disallowance. The IRS will issue a statutory notice of deficiency if the taxpayer has not responded. You then have 90 days to petition Tax Court if you disagree with the determination. However, responding immediately after the deadline may still allow resolution without litigation if documentation is compelling.

Can I request an extension of time to respond to a CP75 notice?

The IRS may grant extensions in limited circumstances. You must submit a written request before the deadline explaining why additional time is necessary. Documentation gathering issues alone rarely justify extensions. Medical emergencies, natural disasters, or death in the family represent more compelling justification. Submit extension requests via certified mail to the address on the CP75 notice.

What if the client no longer has required documentation?

Lost documentation requires recreating the record trail. Contact schools, medical providers, and childcare facilities for duplicate records. Request transcripts from the school district showing enrollment and address. Medical providers maintain records for several years and can provide summaries. Many institutions charge fees for duplicate records, which clients should expect to pay.

How do CP75 examinations affect future tax returns?

Successfully defending a CP75 examination does not prevent future notices. The IRS may examine EITC claims in subsequent years if patterns continue to trigger their systems. However, strong documentation in one year establishes patterns that make future claims more credible. Conversely, denied EITC claims result in increased scrutiny on subsequent returns.

Should I contact the IRS phone number on the CP75 notice?

Phone contact is optional but increasingly difficult. The 2026 compliance phone lines answered only 34% of calls. Written responses create better documentation and ensure deadline compliance. If you do call, document the date, time, representative name, employee ID number, and all information discussed. Follow all phone discussions with written confirmation via certified mail.

What preparer penalties apply for inadequate EITC due diligence?

IRC Section 6695(g) imposes penalties per failure to meet due diligence requirements. For 2026, verify current penalty amounts at IRS.gov as these adjust for inflation annually. Penalties apply separately for each required action: completing Form 8867, computing the credit, maintaining records, and retaining documentation. A single inadequate return can generate multiple penalties.

Can clients amend returns to remove EITC claims to avoid examination?

Taxpayers can file amended returns removing EITC claims before the IRS makes a determination. However, this is rarely advisable if the original claim was legitimate. It signals weakness in your position and does not prevent potential fraud penalties if the IRS believes the original claim was intentionally false. Only amend if documentation review reveals clear ineligibility.

How does the two-year EITC ban affect clients?

The two-year ban applies when the IRS determines the taxpayer claimed EITC due to reckless or intentional disregard of rules. During the ban period, the client cannot claim EITC even if otherwise eligible. The ten-year ban applies to fraudulent claims. These bans significantly impact low-income clients who depend on EITC. Careful documentation prevents ban triggers.

What role do third-party verification services play?

Some practitioners use third-party services to verify addresses, relationships, and other EITC criteria. These services provide documented verification that demonstrates due diligence. However, they do not eliminate your professional responsibility to make reasonable inquiries and exercise judgment. Third-party verification supplements but does not replace practitioner due diligence under Circular 230.
