When you hear “IRS form,” your first thought might be paperwork, deadlines, or penalties. But Form 8867, also called the Paid Preparer’s Due Diligence Checklist, is different. It’s not just about compliance—it’s about protecting both the taxpayer and the tax preparer.
Here’s what it really means and why it matters.
Understanding Form 8867
Form 8867 is required whenever a paid preparer works on a return that claims certain refundable credits or filing statuses. That includes the Earned Income Tax Credit, the Child Tax Credit, the Credit for Other Dependents, the American Opportunity Tax Credit, and Head of Household filing status.
This form must be completed, signed, and submitted with the return. Preparers also keep a copy with supporting documentation for at least three years.
Why the IRS Requires It
Refundable credits can result in significant refunds, but they’re also prone to mistakes and fraud. Form 8867 ensures preparers verify eligibility, rather than simply accepting what a client says.
By signing it, a preparer confirms they asked all the necessary questions, reviewed documentation, calculated credits correctly, and kept accurate records.
Failing to follow these rules can trigger a $600 penalty per failure, per credit.
What It Means for Tax Preparers
For tax professionals, Form 8867 is both a requirement and a safeguard. It documents that due diligence was exercised, eligibility was confirmed, and the process was properly recorded.
It’s more than checking boxes. It protects your practice, ensures compliance with IRS rules and Circular 230, and helps avoid costly penalties.
Preparers must submit the form with every applicable return, calculate credits accurately, retain all supporting records for three years, and follow up when client information seems inconsistent. These steps create a strong defense if the IRS reviews a return.
What It Means for Taxpayers
For taxpayers, Form 8867 may feel like extra questions and paperwork. Your preparer may ask about dependents, income, living arrangements, or schooling—and request supporting documents.
This isn’t mistrust. It’s protection. The form helps ensure the credits you claim are legitimate, your refund is correct, and you’re less likely to face future audits. Extra documentation requests are a good sign that your preparer is following the rules.
How the Form Works
Form 8867 has five main sections. Each section helps ensure accuracy and professionalism:
- Checklist – Confirms the preparer met all due diligence requirements
- Credit Verification – Covers each credit or filing status claimed
- Knowledge Requirement – Confirms reasonable inquiries were made when information seemed inconsistent
- Record Retention – Confirms documents will be kept for three years
- Certification – The preparer signs under penalty of perjury
Each part is designed to show the return was prepared carefully and correctly.
Common Mistakes
Even experienced preparers can overlook details. Common mistakes include failing to ask follow-up questions, not keeping documentation, forgetting to submit Form 8867, or using an outdated version.
Avoid these issues with a strong compliance routine, standardized checklists, internal reviews, and regular due diligence training.
Why It Matters
Form 8867 may seem like bureaucratic red tape, but it serves a vital purpose. For preparers, it proves diligence and professionalism. For taxpayers, it ensures the credits claimed are valid and the return is prepared accurately.
At its core, Form 8867 protects both sides. It ensures tax filings are accurate, accountable, and trustworthy—keeping the process safe for everyone involved.
