A Guide to Navigating an ERC Audit

Is Your ERC Claim Built on Bedrock or Sand? A CEO's Self-Audit Framework

Use this framework to step outside your own perspective and objectively analyze your position for potential weaknesses—before an auditor does it for you.

Part I: The Foundational Self-Audit

Before you assemble any documents, you must first pressure-test the foundation of your claim. Be brutally honest: can you clearly and immediately defend your eligibility based on the strict letter of the law?

• Pinpoint Your Exact Eligibility Justification. You must anchor your claim to one of two specific pillars: a significant decline in gross receipts OR a full or partial suspension of operations due to a specific government order. Vague justifications are the primary red flag for the IRS. Claims based on general "supply chain disruptions," for instance, are rarely sufficient on their own. An auditor will demand proof that your supplier was unable to deliver critical goods because of a government order shutting them down, that you had no viable alternative, and that this specific disruption caused a more-than-nominal impact on your own operations.
• Locate the Specific Government Mandate. If your eligibility rests on a business suspension, you must produce the actual, dated government order that forced the change. This cannot be a mere recommendation from the CDC or a voluntary action. The core of this test is proving the order had a "more than nominal" effect on your business. The IRS has clarified this means the affected part of your business constituted at least 10% of your total gross receipts or 10% of your employees' total service hours compared to the same quarter in 2019. For example, a restaurant forced to close its dining room (representing 80% of its revenue) while keeping its takeout window open (20%) would likely qualify. An office that merely had to stagger employee schedules, impacting efficiency but not shutting down a core revenue stream, has a much harder case to prove.
• Re-verify Your Financials (The Gross Receipts Test). This qualification is purely mathematical, leaving no room for subjective interpretation. Pull your quarterly profit and loss statements and compare them to the baseline year of 2019. The required decline is different for each year.

For 2021, an alternative rule also allows you to qualify for a quarter if the immediately preceding quarter experienced the required 20% decline. The numbers you use must be clean, derived from your formal accounting system, and match the gross receipts reported on your annual income tax returns. An inconsistency here is an immediate red flag.

• Confirm No "Double Dipping" with PPP Loans. One of the most critical

  tax compliance

  issues is the interaction between the ERC and the Paycheck Protection Program (PPP). You absolutely cannot use the same wage expenses to both qualify for PPP loan forgiveness and to calculate your credit. To verify this, pull out your PPP loan forgiveness application. Look at the

  payroll records

  and specific payroll periods you submitted to your lender. Now, compare that to the qualified wages in your ERC calculation worksheet. There must be zero overlap. A prepared

  small business

  owner will have explicitly excluded the wages used for PPP when calculating the ERC.

Part II: Assembling Your Audit-Proof Dossier

Organize it into the following five sections, either digitally in a secure folder or in a physical binder with clear tabs.

• Section 1: The Eligibility Narrative. This one-page executive summary is the most critical piece for framing the entire conversation. Before an auditor even looks at a single number, this memo tells them exactly why you qualified, for which specific quarters, and under which pillar of eligibility (Gross Receipts Test or Government Order Suspension). Write it clearly and concisely. This is your opportunity to take control of the story, demonstrating from the outset that your claim was the result of a deliberate and informed process.
• Section 2: The Government Order Evidence. If your eligibility hinges on a suspension of operations, this section provides irrefutable proof. It must contain a copy of the actual, dated government order(s) that mandated the change. Crucially, you must also include a brief written explanation that connects the dots for the auditor. Detail precisely how the order impacted your business in a more-than-nominal way (e.g., "The state mandate of March 15, 2020, closed our physical storefront, which historically generated 65% of our gross receipts, forcing a suspension of all in-person sales.").
• Section 3: The Financial Proof. Here, the numbers tell the story for a claim based on revenue decline. This section should contain clean, easy-to-read comparative financial statements (such as quarterly Profit & Loss reports) for 2019, 2020, and 2021. An auditor should be able to look at your 2019 statements and the corresponding quarters in 2020 or 2021 and immediately see the required decline in gross receipts. Ensure these figures align perfectly with the gross receipts reported on your business's annual income tax returns.
• Section 4: The Payroll & Calculation Records. This is the mechanical heart of your dossier, proving the accuracy of your credit amount. Include the detailed payroll records or journals for the qualifying quarters. Most importantly, you must provide the exact worksheet or spreadsheet you used to calculate the credit. This calculation must show the qualified wages on a per-employee, per-quarter basis. Finally, include copies of the filed Form 941-X, Amended Employer's Quarterly Federal Tax Return, for each quarter you claimed the credit.
• Section 5: The PPP & Preparer Paper Trail. This final section demonstrates proactive

  tax compliance

  and due diligence. To prove you did not "double-dip," include a complete copy of your Paycheck Protection Program (PPP) loan forgiveness application. This document clearly shows which wages were used to obtain forgiveness, allowing an auditor to verify they were not the same wages used for your ERC calculation. Additionally, if a third-party firm assisted with your claim, include your engagement letter and all substantive correspondence. This documentation is vital, as it demonstrates you performed due diligence—a critical fact if your preparer is later identified as an aggressive "ERC mill."

Part III: Quantifying the Risk of a Failed Audit

Building your dossier is your primary defense, and understanding the severe financial consequences of a failed audit underscores its importance. An auditor isn't just empowered to ask for the credit back; they can impose significant penalties that compound the financial damage. The consequences fall into three distinct levels of severity, each tied to the perceived intent and diligence of the business owner.

• Full Repayment Plus Accrued Interest: This is the baseline consequence. If the IRS determines your claim was invalid—even for an honest mistake—you must return the entire credit amount, plus substantial interest calculated from the date you received the refund.
• The 20% Accuracy-Related Penalty: The IRS can add this penalty if it determines the error was due to negligence or a disregard of the rules. Negligence can be as simple as failing to keep adequate records or accepting a preparer's advice that seemed too good to be true without doing your own due diligence. Your dossier serves as tangible proof that you exercised reasonable care.
• The 75% Civil Fraud Penalty: This catastrophic outcome is reserved for cases with evidence of willful intent to deceive, such as knowingly falsifying documents. It is the primary risk for businesses that used fraudulent "ERC mills" and suspected—or should have suspected—that their claim was built on lies. As tax expert Stephen A. Weisberg, Founder of The W Tax Group, warns about such schemes, "Anyone who's telling you that... they're blatantly lying." This is precisely the type of bad actor the IRS targets with its most severe penalties.

Part IV: Proactive Remediation for At-Risk Claims

What happens when your self-audit reveals a crack in the foundation? This realization is not a moment for panic; it is a critical insight that allows you to shift from defense to proactive risk mitigation. The IRS has created specific programs for taxpayers who want to correct an improper claim, giving you a clear path to regain control.

• The ERC Claim Withdrawal Process: This is your cleanest option if you have filed a claim but have not yet received or cashed the refund check. Withdrawing the claim effectively erases it, preventing any future examination of that filing and neutralizing the risk.
• The ERC Voluntary Disclosure Program (VDP): If you've already received and used the funds, the VDP is an extraordinary opportunity to make things right. This formal program is for business owners who now realize their claim was improper. In exchange for proactive honesty, the IRS offers significant incentives. Participants repay the credit—often at a discount—and the IRS waives penalties and interest. This provides a predictable, financially manageable path to resolving the issue and securing peace of mind. As former IRS Agent Michael D. Sullivan warns, "At some point in time, IRS will be making contact with you... IRS is getting more sophisticated in their income tracking." His insight confirms that waiting and hoping is not a strategy; using the tools the IRS provides is.

Part V: Executing the Plan When an IRS Notice Arrives

With your dossier built, the arrival of an official notice is not a crisis. It is the trigger to execute a clear, professional plan. An audit is a request for verification, and your preparation allows you to manage it like a project, not a panic attack.

When an IRS Notice 6612 or a similar letter arrives, take these immediate, sequential steps:

1. Don't Panic, Read Carefully. Read the entire letter to understand its scope. It will specify the tax periods under review and include a Form 4564, the Information Document Request (IDR). This IDR is your checklist of required documents. Note the response deadline—this is your first project milestone.
2. Engage Your Tax Professional Immediately. Forward a copy of the notice to your CPA or tax attorney. Do not attempt to communicate with the IRS on your own. Your role is CEO; you provide the materials. Their role is to be the expert liaison.
3. Deliver Your Dossier. This is the step that changes the entire dynamic. Provide your tax professional with your complete, organized Audit-Proof Dossier. A swift, comprehensive response signals that you are a serious, organized business owner. Instead of your CPA billing you for weeks spent chasing down scattered documents, they can immediately craft a precise and authoritative response.
4. Protect Your Time. The ultimate benefit of this approach is the protection of your focus. By transforming the audit into a managed process, you sidestep the frantic, time-consuming scramble that derails so many leaders. You delegate the execution to your expert team and stay focused on running your business.

Frequently Asked Questions

• What is the statute of limitations for an ERC audit? Generally, the IRS has three years from the date you filed your payroll tax return to initiate an audit. However, if you filed an amended return (Form 941-X) to claim the ERC, the three-year clock resets from the date the amended return was filed. For claims made for the third and fourth quarters of 2021, Congress extended the statute of limitations to five years. In cases of suspected fraud, there is no statute of limitations.
• What if the company that prepared my ERC claim was fraudulent? Am I still responsible? Yes. The IRS is clear that taxpayers are always responsible for the information on their tax returns, even if a third party prepared it. The business owner is ultimately on the hook for repaying an improper credit, along with any penalties and interest. This is why documenting your own due diligence in the dossier is so important—it demonstrates your good faith, even if you were misled.
• Can I still use the ERC Voluntary Disclosure Program (VDP)? Yes, the IRS has reopened the ERC Voluntary Disclosure Program through November 22, 2024. Under the current program, businesses that have already received and spent the funds can repay 85% of the credit received. In exchange, the IRS will not charge penalties or accrued interest, and you will not be audited for the ERC claim in the quarters you resolve. This program is for those who have already received their refund; if you have a pending claim you now believe is incorrect, the claim withdrawal process is your appropriate tool.
• What are the biggest "red flags" that might trigger an ERC audit? Common triggers include: relying on generic "supply chain disruptions" without a specific government order; claiming eligibility for every single available quarter; inconsistencies between

  payroll records

  and income tax returns; failing to reduce wage deductions on your income tax return by the amount of the credit; and using a known "ERC mill" that the IRS is actively tracking.
