ERC Audit Defense & Clawback Recapture Letters

What to do if the IRS is auditing your Employee Retention Credit claim, disallowing it, or demanding the money back — and how Mike Habib, EA, a Whittier, California tax representation firm, defends these cases.

If you claimed the Employee Retention Credit and a letter from the IRS just arrived, you are not alone, and you are not necessarily in trouble. Hundreds of thousands of businesses claimed the ERC during and after the pandemic, and the IRS is now working through those claims in three distinct ways: auditing claims that have not yet been paid, disallowing claims outright, and — in the situation that causes the most alarm — demanding repayment of money that has already landed in a business bank account.

This is not a small compliance footnote. The IRS has issued more than 84,000 disallowance letters and, as of its most recent public disclosures, tens of thousands of recapture letters seeking to claw back credits that were already paid, covering hundreds of millions of dollars. A new law passed in 2025 extended the IRS audit window specifically for certain 2021 quarters from five years to six, meaning the agency now has until 2027 or later to open an ERC file that a business owner assumed was long settled.

This guide walks through exactly what the ERC was, why so many claims are now under scrutiny, what each type of IRS letter means, what your realistic options are once you receive one, and how Mike Habib, EA — a Whittier, California based tax representation practice — approaches these cases. Every dollar figure, code section, and deadline in this guide has been checked against the IRS’s own published guidance and the text of the relevant statute before being written down.

Part One: What the Employee Retention Credit Actually Was

What Was the ERC, in Plain Terms?

The Employee Retention Credit was a refundable payroll tax credit created by the CARES Act in March 2020 to encourage employers to keep employees on payroll during the pandemic. It was not a loan. It was not something you had to pay back if your business used the money correctly. Employers claimed it against their share of Social Security tax, and if the credit exceeded what they owed, the IRS sent a refund check for the difference.

The credit went through several rounds of expansion. For 2020, eligible employers could claim 50% of qualified wages, up to $10,000 in wages per employee for the entire year — a maximum credit of $5,000 per employee. For 2021, Congress made the credit far more generous: 70% of qualified wages, up to $10,000 in wages per employee, per quarter — a maximum credit of $7,000 per employee, per quarter, available for the first three quarters of 2021. That meant an employer could claim as much as $21,000 per employee for 2021 (three quarters at $7,000 each), plus the $5,000 from 2020, for a combined maximum of $26,000 per employee across both years.

A special category, the Recovery Startup Business provision, allowed businesses that began operating after February 15, 2020 and had average annual gross receipts under $1 million to claim up to $50,000 per quarter for the third and fourth quarters of 2021 — up to $100,000 total — without needing to show a government shutdown or a decline in revenue at all.

How Did a Business Actually Qualify for the ERC?

Eligibility ran through four distinct paths, called eligibility pillars, and a business only needed to satisfy one of them for a given calendar quarter:

• Government order suspension. A federal, state, or local government order fully or partially suspended the business’s operations during the quarter. A partial suspension had to affect more than a nominal portion of the business — generally understood as at least 10% of gross receipts or at least 10% of the hours of service attributable to the suspended portion, compared to the same period in 2019.
• Significant decline in gross receipts. For 2020, the business needed a gross receipts decline of more than 50% in a calendar quarter compared to the same quarter in 2019. For 2021, the bar dropped substantially — more than 20% (i.e., gross receipts below 80% of the 2019 comparison quarter). This is generally considered the most defensible eligibility basis, because it is a straightforward numerical comparison rather than a judgment call.
• Recovery Startup Business. Available only for the third and fourth quarters of 2021, for businesses that began operating after February 15, 2020, had one or more W-2 employees, and had average annualized gross receipts under $1 million. These businesses did not need to show a shutdown or revenue decline at all.
• Severely financially distressed employer. A narrow category for the third and fourth quarters of 2021 only, for employers whose gross receipts had declined by more than 90% compared to the same 2019 quarter, which allowed a large employer to treat all wages as qualified rather than only wages paid to employees not providing services.

Each of these tests has its own documentation requirements, and — this matters enormously for what comes next — each one carries a very different level of IRS audit risk. The gross receipts test is a numbers exercise: pull the 2019 and 2020/2021 financials, do the math, and the answer is largely objective. The government-order suspension test is where most disputes arise, because “more than nominal” and “government order” are open to interpretation, and promoters marketing the credit stretched those interpretations well past what the IRS now says the law supports.

Why Is the IRS Treating So Many ERC Claims as Suspect?

Because the credit was, by design, easy to claim and hard to verify at the time. A business filed Form 941-X, an amended payroll tax return, for each eligible quarter, checked boxes describing why it qualified, calculated the credit, and the IRS — under enormous processing pressure and with limited staff to verify each claim before paying it — issued the refund. This “pay first, verify later” model is exactly why the IRS is now conducting after-the-fact reviews on a massive scale.

It gets worse. The credit spawned an entire industry of ERC “mills” — firms with no prior tax practice that advertised aggressively, promised businesses they qualified regardless of the facts, took a contingency fee (often 15–25% of the refund), and moved on. Many of these firms stretched the government-order suspension test past any reasonable reading, told businesses with stable or growing revenue that they qualified anyway, or claimed the credit for owners’ wages and family members who are excluded by the related-party rules under IRC section 51(i). The IRS has repeatedly listed ERC promotion schemes on its “Dirty Dozen” list of tax scams, and it has pursued criminal charges against some of the most aggressive promoters.

The result is that a genuinely qualified business and a business that was talked into an improper claim by an aggressive promoter can look identical from the outside — both have a large refund check that arrived a year or two after filing. The IRS cannot tell the difference without asking, which is exactly what it is now doing at scale.

Part Two: The Three Letters — Disallowance, Audit, and Recapture

Letter 105-C: Full Disallowance of an Unpaid Claim

If your ERC claim has not yet been paid and the IRS decides it does not qualify, you receive Letter 105-C, Claim Disallowed. This is the IRS telling you, in writing, that it is denying your refund claim in full for the tax period stated in the letter. Nothing has been paid yet, so there is no money to send back — but the door on that quarter’s credit is being closed.

You have real rights here, and they matter. From the date on the letter, you have two years to either appeal the disallowance to the IRS Independent Office of Appeals or file suit in the United States District Court or the United States Court of Federal Claims. Practically, though, the IRS recommends sending your written protest within 30 days of the letter to help preserve the two-year window and keep the case moving through the administrative process rather than defaulting toward litigation. If a representative is handling your dispute, a Form 2848, Power of Attorney and Declaration of Representative, needs to be on file so the representative can act on your behalf.

Letter 106-C: Partial Disallowance of an Unpaid Claim

Letter 106-C works the same way, except the IRS is only disallowing part of your claim — either reducing the amount for a quarter, or disallowing the ERC entirely while allowing you to claim something else on the return instead. The same two-year appeal or litigation window applies, measured from the date on the letter. One important difference: if you do nothing in response to a 106-C, the IRS will simply refund the portion of the credit it has determined you are entitled to. That is very different from doing nothing after a 105-C, where nothing gets refunded at all.

For both 105-C and 106-C letters, if the amount in dispute is over $25,000, a formal written protest is generally required rather than a short informal response. The protest needs to state, in writing, that you intend to appeal, identify the tax periods and letter you are disputing, list each item you disagree with and why, and set out the facts supporting your position.

Letter 6612 With Form 4564: You Are Being Audited

If your claim has not been paid yet and the IRS wants to look closely at it before deciding, you may receive an audit notice — commonly Letter 6612, accompanied by Form 4564, Information Document Request. This is a full examination, not an automated notice. The IRS is asking for the substantiation behind your eligibility determination: the government orders you relied on, the gross receipts calculations, the payroll records, the methodology used to determine which wages were “qualified wages,” and often an explanation of how a promoter or preparer arrived at the number claimed.

The IRS generally does not explain why a particular claim was selected for examination. It could be the size of the credit, the eligibility basis claimed, red flags associated with the preparer who filed it, or simply random selection from a risk-model output. What matters is that once an examination letter arrives, how the business responds substantially determines the outcome. A well-organized, complete response that ties every dollar of the claimed credit to specific documentation gives the examiner a reason to close the case with no change. A vague or incomplete response almost always leads to a proposed disallowance.

Letter 6577-C: The Recapture Letter — the One That Arrives After You Already Have the Money

This is the letter that causes the most panic, and understandably so. Letter 6577-C is sent after your ERC refund has already been paid. It tells you the IRS believes the refund was too large — or should not have been paid at all — and it is now formally seeking to recover the money, plus interest, and often with the recovered amount then assessed as an additional tax liability.

Many 6577-C letters focus on a specific, mechanical issue: a mismatch between the number of employees reported on the originally filed Form 941 and the number implied by the size of the ERC claimed. The IRS’s recapture program leans heavily on this comparison because it can be run by computer across a huge number of accounts without a human examiner looking at the underlying facts. The problem — and it is a real one — is that Form 941 often does not capture the full picture. It reflects a snapshot of a specific pay period, not the total number of people who worked for the business across an entire quarter, and it says nothing about which wages were properly treated as “qualified wages” under the detailed rules. A business can be completely correct on its ERC claim and still receive a 6577-C simply because the IRS’s automated comparison flagged an apparent mismatch that a closer look at full quarterly payroll records would resolve.

The response window on a 6577-C is tight: 21 days from the date on the letter. Because these letters are mailed and often take close to two weeks to arrive, the real working window to gather documentation and respond can be closer to one week. This is not a deadline to treat casually — missing it can move the case directly into assessment and collection.

How Large Is This Enforcement Effort, Really?

Large, and still growing. Based on the IRS’s own public disclosures and inspector general reporting, the agency has issued more than 84,000 disallowance letters (105-C and 106-C combined) and, in an earlier wave alone, sent recapture letters covering more than 22,000 tax periods and roughly $573 million in previously paid ERC refunds — a figure that has grown substantially since that initial disclosure as the IRS continues sending 6577-C letters. Audit letters under the Letter 6612 examination process continue to go out on an ongoing basis. Put together, well over 100,000 businesses have now received some form of adverse IRS action on an ERC claim, and IRS officials have indicated this enforcement effort will continue for years, not months.

Part Three: The Statute of Limitations Just Got Longer

How Long Does the IRS Have to Audit an ERC Claim?

This is where a lot of business owners have been operating on outdated assumptions, and it is worth being precise, because the rules are not the same for every quarter.

Under the general rule in Internal Revenue Code section 6501, the IRS has three years from the date a return is filed to assess additional tax. Because most ERC claims were made by filing an amended payroll return (Form 941-X) rather than the original Form 941, the three-year clock generally runs from the date the amended return was filed, not from the original quarter. For 2020 quarters, that assessment window has already closed for the vast majority of claims — it expired April 15, 2024. For the first and second quarters of 2021, the standard window closed April 15, 2025.

The third and fourth quarters of 2021 are a different story, and this is the part that matters most going forward. Congress had already extended the assessment period for ERC claims tied to those two quarters to five years in earlier legislation. Then, the One Big Beautiful Bill Act, signed into law July 4, 2025, extended it further to six years, running from the later of the date the original employment tax return was filed (or treated as filed) for the relevant quarter, or the date the ERC claim itself was filed. In practical terms, for many Q3 and Q4 2021 claims, this pushes the IRS’s assessment deadline out to around April 15, 2028, and in some cases later depending on when the claim was actually submitted.

None of these deadlines apply if fraud or a substantial misrepresentation of a material fact is involved — in those cases, there is effectively no statute of limitations at all, and the IRS can pursue the matter indefinitely. This is one more reason that getting a second, independent look at a promoter-prepared claim matters: an inflated or fabricated eligibility basis does not become safer with time. It becomes a fraud exposure that never expires.

What About Claims That Were Filed but Never Processed?

The One Big Beautiful Bill Act also addressed the large backlog of claims still sitting in the IRS pipeline. It disallows, retroactively, any pending ERC claim for the third or fourth quarter of 2021 that was filed after January 31, 2024. This provision only reaches claims that had not yet been paid as of the law’s enactment — if you already received your refund before July 4, 2025, this change does not touch it, and 2020 claims and first/second quarter 2021 claims are entirely unaffected regardless of when they were filed. But if you filed a Q3 or Q4 2021 claim after January 31, 2024, and it is still sitting unprocessed, you should assume it will be formally disallowed and plan accordingly rather than waiting for a refund that the law now says cannot legally be issued.

Part Four: The Real Cost of an Improper Claim

If a Claim Is Disallowed After the Money Is Already Spent, What Does It Actually Cost?

More than just the credit amount, and this is where businesses are often caught badly off guard. Three separate cost components can stack on top of the original refund:

• The recaptured credit itself — the full amount the IRS determines you were not entitled to, assessed back as a liability.
• Interest, running from the date the original refund was paid to you, not from the date the IRS catches the error. Interest on erroneous refunds compounds daily, and the current individual underpayment rate is 7% per year (set quarterly under IRC section 6621; the rate for the quarter beginning October 1, 2026 was confirmed unchanged at 7% for individuals, 6% for corporations, in the IRS’s most recent quarterly interest announcement). Because ERC audits are often happening two, three, or more years after the refund was issued, the interest component alone can be substantial — a $200,000 refund paid in 2022 and recaptured in 2026 can easily carry $30,000 to $40,000 in accrued interest on top of the principal.
• The erroneous claim penalty under IRC section 6676 — a 20% penalty on the “excessive amount” of the claim, meaning the portion of the refund that exceeded what you were actually entitled to. If you claimed $300,000 and the IRS determines only $100,000 was proper, the excessive amount is $200,000, and the penalty is $40,000 on top of everything else. This penalty applies unless you can show reasonable cause, and — importantly — it is a strict-liability style penalty in the sense that the IRS does not have to prove negligence or intent; the mere fact that the claim was excessive is generally enough unless reasonable cause is established.

Put together, a business that received a $250,000 ERC refund it was not entitled to, and that gets caught three years later, is not looking at repaying $250,000. It is realistically looking at $250,000 in principal, roughly $35,000 to $50,000 in accumulated interest, and potentially $50,000 in erroneous claim penalties — well over $300,000 in total exposure on a $250,000 mistake.

What if the Promoter Who Prepared the Claim Gets in Trouble — Does That Help Me?

Not directly, and this is a hard truth business owners need to hear early rather than discovering it later. The ERC was claimed by the business, on the business’s payroll tax return, under the business’s Employer Identification Number. The liability to repay an improper claim rests with the business that received the refund, regardless of who prepared it or how aggressively it was marketed.

That said, the One Big Beautiful Bill Act did add new accountability measures aimed at ERC promoters — including due diligence requirements when determining a taxpayer’s eligibility or credit amount, with a $1,000 penalty per failure to comply for promoters who do not meet those standards (professional employer organizations are excluded from this specific requirement). Some businesses that paid a promoter a contingency fee for a claim that later proved improper have pursued separate legal claims against the promoter to recover fees paid, but that is a civil dispute between the business and the promoter — it happens on a completely separate track from the business’s obligation to the IRS, and it does not pause or reduce what is owed to the government.

Part Five: How to Actually Respond

The First Move: Figure Out Which Letter You Actually Have

This sounds obvious, but it is the single most common point of confusion, because the four letters described above call for genuinely different responses. Receiving a Letter 6612 examination request and responding as though it were a 6577-C recapture (or the reverse) wastes the limited time available and can miss the actual deadline that applies to your situation. The first step in every case is identifying, from the letter number printed on the notice itself, exactly which process you are in: an unpaid claim being disallowed (105-C/106-C), an unpaid claim under active examination (6612/Form 4564), or a paid claim the IRS wants back (6577-C).

Once that is established, the second step is finding the date printed on the letter — not the date it arrived, not today’s date — because every deadline in this process is calculated from that printed date. Missing a response window by even a few days can convert a negotiable dispute into a final assessment with no further administrative recourse.

Reconstructing the Eligibility File, Quarter by Quarter

Whether responding to an audit or contesting a disallowance, the substance of the defense is the same: proving, quarter by quarter, that the eligibility test claimed was actually met and that the wages counted were properly “qualified wages” under the rules in effect for that quarter.

For a gross receipts decline claim, this means assembling the actual 2019 and 2020/2021 financial records — not summaries, not estimates, but the underlying figures that support the percentage decline calculated on the original Form 941-X. For a government-order suspension claim, this means identifying the specific government order relied upon, showing that it was in effect during the specific dates claimed, and demonstrating that the suspension affected more than a nominal portion of operations — generally documented against the 10% threshold for either gross receipts or hours of service. For a Recovery Startup Business claim, this means documenting the entity’s formation date, first employee hire date, and the calculation showing average annualized gross receipts stayed under the $1 million threshold.

Every claim also has to survive the related-party wage exclusion under IRC section 51(i), which disallows credit for wages paid to majority owners and their family members in many ownership structures — one of the most common errors found in promoter-prepared claims, because many mills simply included every W-2 on the payroll without checking ownership attribution rules.

Filing a Formal Protest for Disallowed Claims Over $25,000

When a 105-C or 106-C disallows more than $25,000 for any tax period, the IRS requires a formal written protest rather than an informal letter. The protest has to include, at minimum: a statement that you want to appeal the determination to the IRS Independent Office of Appeals; your name, address, and daytime phone number; the specific tax periods and letter number involved; an itemized list of each adjustment you disagree with; the facts supporting your position on each disputed item; and the law or authority supporting your position, where applicable. A properly prepared protest, filed within the 30-day window recommended by the IRS to protect the broader two-year appeal right, is what actually gets a case in front of an Appeals officer rather than defaulting into litigation as the only remaining option.

Responding to a 6577-C Recapture Letter Within 21 Days

Because the working window on a recapture letter is so short, the response has to be organized before the letter even arrives if there is any advance warning that one is coming — for example, if the business already knows its claim rested on a weak eligibility basis. Where the letter has already arrived, the priority is immediate: pull the full quarterly payroll register (not just the Form 941 snapshot the IRS is comparing against), reconcile the actual employee count and qualified wages for the specific quarter in dispute, and submit a response that directly addresses the mismatch the IRS is alleging rather than a general defense of the claim as a whole. Many 6577-C disputes are resolved successfully precisely because the underlying facts were fine all along — the IRS’s automated employee-count comparison was simply working from incomplete information.

What the IRS Independent Office of Appeals Actually Does Differently

The Independent Office of Appeals is organizationally separate from the examination function that issued the disallowance or the audit determination. Appeals officers were not involved in the original decision, are not measured on sustaining it, and apply a settlement standard the examiner does not use: they weigh the “hazards of litigation” — the realistic likelihood that the government would win, lose, or partially lose the specific issue if it went to court. That is a fundamentally different conversation than the one with an examiner who is simply checking whether documentation matches a checklist. A well-organized protest that highlights genuine legal or factual uncertainty in the government’s position can result in a negotiated resolution at Appeals that would never have been available at the examination level.

Part Nine: The Documentation Standard the IRS Actually Applies

Why “We Had a Rough Year” Is Not Enough

One of the most common mistakes in ERC defense is treating the eligibility test as a narrative rather than a calculation. Telling an examiner that a business “struggled during COVID” or that “the government made us close for a while” describes a general hardship, not a documented eligibility basis under the specific statutory tests. The IRS is not evaluating whether your business had a hard year — plenty of businesses did and did not qualify for the ERC. It is evaluating whether the specific, numerical test for a specific quarter was actually met and can be shown with records.

For the gross receipts test, that means producing the actual quarterly gross receipts figures for 2019 and the comparison year, calculated the same way both times (cash basis versus accrual basis matters, and switching methods between the two years to manufacture a bigger decline is exactly the kind of inconsistency an examiner is trained to catch). For the government-order suspension test, it means identifying the specific order by name, agency, and effective dates, and showing — with a calculation, not just an assertion — that the affected portion of the business met the more-than-nominal threshold.

The Aggregation Rules Trip Up More Claims Than Almost Anything Else

If a business operates through more than one entity under common ownership or control, the ERC eligibility rules generally require treating those entities as a single employer for purposes of determining eligibility and the applicable employee-count thresholds. This aggregation requirement, drawn from existing controlled-group rules under IRC sections 52 and 414, is one of the most frequently misapplied parts of the ERC — and one of the most common issues IRS examiners specifically probe.

Here is why it matters so much: a business owner with three related entities — say, a restaurant, a catering company, and a real estate holding entity that owns the building — may have looked at each entity separately when determining eligibility, when the rules generally required looking at gross receipts and operations across all three combined. Depending on the facts, aggregation can either help a claim (if one struggling entity pulls the combined picture below the eligibility threshold) or hurt it (if a healthy entity within the group means the combined picture does not show the decline that any single entity might show on its own). Many promoter-prepared claims simply ignored aggregation altogether, checking eligibility entity by entity because it was faster and produced a bigger number. When an examiner catches this, the entire claim for the improperly analyzed entities can unravel at once.

The Related-Party Wage Exclusion, Explained Without the Jargon

Internal Revenue Code section 51(i) — imported into the ERC rules by reference — disallows the credit for wages paid to certain relatives of a majority owner, and, depending on the ownership percentage and family relationships involved, can disallow wages paid to the majority owner as well. This rule exists because the ERC was designed to encourage employers to retain their broader workforce, not to subsidize wages an owner would have paid to family members regardless of the pandemic.

In practice, this shows up constantly in small and family-owned businesses: a spouse on payroll, an adult child working in the business, a sibling who co-owns and also draws a salary. Many ERC mills either did not know this rule existed or did not bother checking ownership attribution before including every W-2 employee in the qualified wage calculation. When this shows up in an audit, it is usually a straightforward, mechanical correction — remove the improperly included wages, recalculate the credit for the affected quarters — but it can meaningfully reduce the credit amount, and if the excluded wages represent a large share of a small business’s payroll, the reduction can be substantial.

Where the Line to Criminal Exposure Actually Sits

It is worth being direct about this, because business owners are often unsure how worried to be. The overwhelming majority of ERC audits, disallowances, and recapture actions are civil matters — the IRS is correcting an erroneous claim, not building a criminal case. Civil ERC enforcement results in repayment, interest, and potentially the 20% erroneous claim penalty, but not criminal charges, for the vast majority of businesses working through this process in good faith.

Criminal exposure becomes a real concern in a narrower set of circumstances: claims involving fabricated documentation, businesses that did not actually exist or have employees during the periods claimed, coordinated schemes involving promoters who filed claims for businesses with no legitimate basis at all, or situations where a business owner was told directly by a preparer that the claim did not qualify and filed it anyway. The Department of Justice has pursued criminal charges against a number of ERC promoters operating what amounted to organized fraud schemes, filing thousands of claims for businesses with little or no legitimate eligibility. If your situation involves anything resembling fabricated records, invented employees, or a claim you knew at the time did not have a real basis, that is a fundamentally different conversation than a good-faith claim with a weak eligibility argument, and it needs to be treated that way immediately — including, in genuinely serious cases, involving an attorney rather than proceeding through the ordinary civil examination and appeals process alone.

Part Ten: If You Have an Unaudited Claim Sitting on the Books

Should You Wait and Hope the Audit Window Passes, or Get Ahead of It?

For businesses that claimed the ERC and have not yet heard from the IRS, the temptation to simply wait is understandable — no letter has arrived, so why invite scrutiny? But given the extended six-year assessment window now in place for third and fourth quarter 2021 claims, “waiting it out” for those quarters means waiting until roughly 2028, not a year or two. For 2020 and first/second quarter 2021 claims, the standard assessment window has already closed for most businesses, which meaningfully reduces (though under a fraud theory, does not eliminate) audit risk on those specific quarters.

The more useful question is not whether to wait, but whether the underlying documentation would hold up if a letter did arrive tomorrow. A proactive eligibility review — done on your own timeline, without a 21-day or 30-day clock running — allows a business to identify weak spots, gather supporting records while people who can explain the original decisions are still around and memories are still fresh, and, where appropriate, get ahead of a problem rather than reacting to one. This is particularly valuable for businesses currently going through a sale, refinancing, or ownership transition, where buyers and lenders are increasingly asking pointed questions about ERC exposure specifically because of the extended audit window — an unresolved ERC question can complicate or delay a transaction that has nothing else to do with it.

What a Proactive Review Actually Looks Like

Mike Habib, EA can review an existing, already-paid ERC claim the same way an IRS examiner would: identifying which eligibility test was used for each quarter, checking whether the aggregation rules were properly applied across related entities, confirming the related-party wage exclusion was correctly handled, and assembling the documentation that would need to be produced if a Letter 6612 or 6577-C arrived. Where the review finds the claim solid, the business now has an organized file ready to respond quickly if the IRS ever does ask. Where the review finds real weaknesses, the business has the opportunity to plan for that exposure on its own terms — financially and strategically — rather than discovering it for the first time under a 21-day deadline with the money already spent.

Part Six: Questions Business Owners Actually Ask

Part Seven: How These Cases Actually Play Out

Scenario 1: The Recapture Letter Based on an Employee-Count Mismatch

A retail business with 42 employees claimed the ERC across three quarters of 2021 based on a gross receipts decline. Roughly eighteen months after receiving a refund of approximately $180,000, the business received a Letter 6577-C stating that the number of employees reported on its Form 941 for one of the quarters did not support the size of the credit claimed, and demanding repayment of the full amount plus interest.

The actual problem was mechanical: the business had used a professional employer organization for part of the year and switched payroll providers mid-quarter, which meant a single Form 941 filing for that quarter did not reflect the full employee count across the entire period — exactly the kind of gap the IRS’s automated matching process is prone to creating. Mike Habib pulled the complete payroll register across both providers for the disputed quarter, reconciled the actual employee count and qualified wages against the original ERC calculation, and submitted a response within the 21-day window with the full documentation attached. The recapture was withdrawn in full once the complete picture was in front of the IRS; nothing was owed.

Scenario 2: The Promoter-Driven Claim With a Genuinely Weak Eligibility Basis

A professional services firm with steady, uninterrupted revenue throughout the pandemic was approached by an ERC marketing firm that prepared and filed claims for all four eligible quarters based on a government-order suspension theory — arguing that local capacity restrictions on in-person meetings constituted a qualifying partial suspension. The firm received a refund of roughly $310,000 and, about two years later, received Letter 6612 opening a full examination.

On review, the eligibility theory was thin: the firm’s revenue had not meaningfully declined, most work continued via video conference throughout the restricted period, and the “more than nominal” threshold on the suspension test was not well supported. Rather than defending an unwinnable position and risking the erroneous claim penalty being assessed on the full amount, Mike Habib negotiated a partial resolution during the examination — conceding the weaker two quarters while preserving and substantiating the two quarters where the firm genuinely had qualifying declines under the alternative gross receipts test that had not originally been claimed. The final assessed recapture was reduced to roughly 40% of the original refund, and — because the case was resolved at the examination stage with a cooperative, well-documented response — the IRS did not pursue the 20% erroneous claim penalty under IRC section 6676 on the conceded amount.

Scenario 3: A Clean Claim Disallowed by an Overwhelmed Examiner

A restaurant group with a legitimate government-ordered closure during 2020 received a Letter 105-C fully disallowing its ERC claim for two quarters, on the stated basis that the business had not adequately demonstrated the shutdown affected more than a nominal portion of operations. The underlying facts were solid — full closure of indoor dining under a documented county health order — but the original submission to the IRS had not included the specific supporting documentation the examiner needed to make that finding.

Mike Habib filed a formal written protest within 30 days, attaching the specific county health orders by date, revenue records showing the closure period, and a calculation walking through the nominal-portion threshold explicitly. The case moved to the Independent Office of Appeals, where an Appeals officer — applying the hazards-of-litigation standard rather than a documentation checklist — reversed the disallowance in full.

Part Eight: How Mike Habib, EA Handles ERC Cases

Start With an Honest Eligibility Review, Not an Automatic Defense

The first step in every ERC case is the same, and it is not what most people expect: an honest, independent review of whether the original claim actually holds up, quarter by quarter, against the specific eligibility test that was used. This matters because the right strategy is completely different depending on the answer. A claim with a solid factual basis that simply lacks organized documentation needs a documentation and protest strategy. A claim with real weaknesses needs a negotiation strategy that protects what can be defended and manages exposure on what cannot. Defending every dollar of a weak claim as though it were airtight is how businesses end up with the full erroneous claim penalty stacked on top of the recapture, when a more candid approach at the examination or protest stage could have avoided it.

Reconstruct the File the Way an Examiner or Appeals Officer Needs to See It

Once the honest assessment is done, the file gets built properly: the specific eligibility test identified for each quarter, the underlying financial records or government orders that support it, the qualified wage calculation reconciled against actual payroll records (not just the Form 941 snapshot), and the related-party wage exclusion checked and applied correctly. This is detailed, methodical work, and it is exactly the kind of reconstruction that a business without an in-house tax function struggles to do well under a 21-day or 30-day deadline while also running the business.

Handle the IRS Correspondence and Deadlines Directly

Once a Form 2848 Power of Attorney is on file, Mike communicates with the IRS examiner, the Appeals officer, or the recapture unit directly, on your behalf. Every deadline — the 21 days on a 6577-C, the 30 days recommended on a 105-C or 106-C, the response window on a Letter 6612 examination — is calendared and protected. The business owner is not the one on the phone trying to explain payroll mechanics to an IRS agent while also running daily operations.

Why Flat-Fee Representation Matters for ERC Cases Specifically

ERC cases often involve real money — refunds in the tens or hundreds of thousands of dollars, sometimes more for larger employers. An hourly billing structure creates exactly the wrong incentive in a case like this: the more back-and-forth with the IRS, the more documents that need review, the more the meter runs, right when the business is already dealing with a demand for repayment.

Mike Habib, EA represents ERC cases at a flat fee, quoted from the scope of work needed once the eligibility review is complete and the letter type is identified. You know the cost of representation before the work begins. The fee does not grow because the IRS takes longer to respond, because Appeals review adds months to the timeline, or because a case needs a second round of documentation. That predictability matters enormously when a business is already staring at a demand for six figures.

What to Do Right Now if You Have an ERC Letter

Find the letter number and the date printed on it. That single piece of information determines every deadline that applies to your case. If you have a 6577-C, you likely have days, not weeks, to act. If you have a 105-C or 106-C, you have more room but still need to move quickly to preserve the option of a protest rather than defaulting into litigation as your only path. If you have a Letter 6612 examination request, the response deadline printed on that letter governs.

Call Mike Habib, EA at 562-204-6700 or 1-877-788-2937. Or ONLINE to set up a consultation. Bring the letter, the original ERC claim documentation if you have it, and your payroll records for the quarters in question.

The eligibility review — an honest look at whether the original claim holds up and what the realistic exposure actually is — typically takes a few days once the documentation is in hand. From there, you get a flat-fee quote for the specific work your case needs: a protest, an audit response, a recapture defense, or a negotiated resolution. No hourly meter, no guessing about cost, no navigating IRS deadlines alone while running your business.

An ERC letter is not a reason to panic. It is a reason to respond correctly, on time, with the right documentation behind you.
