Employee Retention Credit Explained

The Employee Retention Credit (ERC) program stands as one of the most substantial tax relief measures introduced during the COVID-19 pandemic, offering eligible employers a refundable tax credit for retaining employees on payroll during periods of economic hardship. This federal payroll tax incentive was designed to help businesses affected by government-ordered shutdowns or significant decline in gross receipts maintain their workforce rather than resorting to layoffs.

The ERC program was subsequently amended by several legislative acts, which expanded and changed its scope over time to include more employers and adjust eligibility and credit amounts.

ERC Program Overview

ERC Credit Amounts and Eligibility

The direct answer: The Employee Retention Credit ERC is a refundable credit against employment taxes that allowed eligible employers to claim up to $5,000 per employee for 2020 and up to $21,000 per employee for 2021 (or $28,000 total per employee across both years), based on qualified wages paid during eligible quarters within the applicable specified time period.

By reading this guide, you will:

• Understand the specific eligibility requirements and how to determine if your business qualifies
• Learn how to calculate your potential credit amount for both 2020 and 2021 quarters
• Master the application process, including which forms to file and when
• Avoid common mistakes that lead to claim denials or IRS audits
• Know the current filing deadlines and what opportunities remain

Please note: As of September 14, 2023, the IRS temporarily stopped processing forms for new claims for the Employee Retention Credit due to widespread improper claims. The IRS announced it would not process new claims for the Employee Retention Credit until at least January 2, 2024, and placed a moratorium on processing new ERC claims filed after January 31, 2024, due to fraudulent or improper applications. The One Big Beautiful Bill Act made the temporary processing suspension of new claims for the Employee Retention Credit permanent. The claim period for the Employee Retention Credit ended on April 15, 2025.

Understanding the ERC Program

The Employee Retention Credit functions as a federal tax incentive that directly reduced employment tax liability for businesses that retained employees during COVID-19-related disruptions. The ERC was established as part of the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) to help employers during the COVID-19 pandemic. Unlike typical deductions, this refundable tax credit provides dollar-for-dollar value—meaning employers could receive refunds even if their credit exceeded their tax liability for a given quarter.

The program’s relevance extends beyond immediate cash flow relief. The ERC was designed to encourage employers to retain employees during pandemic-related business shutdowns and slowdowns. For many eligible businesses, the ERC represented a critical lifeline that enabled them to maintain business operations, preserve institutional knowledge by keeping trained employees, and position themselves for recovery as economic conditions improved. In particular, government orders that resulted in the partial or full suspension of the employer’s operations—such as mandated closures or restrictions—directly impacted eligibility for the credit.

ERC Program Timeline and Legislative History

The CARES Act, signed into law on March 27, 2020, introduced the employee retention credit (ERC) for wages paid between March 12, 2020, and December 31, 2020. The ERC law was subsequently amended by several legislative acts, which expanded and changed the program over time. Under these initial parameters, the program offered a credit equal to 50% of qualified wages up to $10,000 per employee for the calendar year—yielding a maximum credit of $5,000 per employee.

Subsequent legislation dramatically expanded the program’s scope and value. The Consolidated Appropriations Act, 2021 extended eligibility through June 30, 2021, while increasing the credit rate to 70% and allowing $10,000 in qualified wages per calendar quarter rather than annually. The American Rescue Plan Act further extended the program through September 30, 2021, and introduced the recovery startup business category for new entities.

The ERC was retroactively eliminated as of September 30, 2021, except for recovery startup businesses, which could claim the credit through the third and fourth quarters of 2021. The claim period for the Employee Retention Credit ended on April 15, 2025. Employers can still file for the ERC retroactively by amending their tax returns for the applicable quarters until April 15, 2025. Current filing deadlines for amended returns are:

• 2020 quarters: April 15, 2024 (deadline passed)
• Q1 & Q2 2021: April 15, 2025
• Q3 & Q4 2021 (recovery startups): April 15, 2027

This timeline directly impacts which businesses can still file ERC claims and underscores the urgency for those who haven’t yet submitted their adjusted employment tax return for eligible quarters.

Core ERC Program Requirements

An eligible employer under the ERC program includes both for-profit businesses and tax exempt organizations that meet specific criteria. To be eligible for the employee retention credit, an employer must have either experienced a full or partial suspension of operations due to a government order related to COVID-19, or demonstrated a significant decline in gross receipts compared to the same calendar quarter in 2019. A household employer is not eligible for the Employee Retention Credit.

Qualified wages include compensation paid to employees plus qualified health plan expenses allocable to those wages. Only paid qualified wages during eligible periods count toward the credit. Wages paid to a majority owner or their spouse are generally not considered qualified wages under IRS guidance. Self-employed individuals may take the Employee Retention Credit for the wages paid to their employees, but cannot include their own self employment earnings. However, the same wages cannot be used both for ERC and for other credits or programs—employers cannot count wages used for Paycheck Protection Program loan forgiveness as qualified employee wages for the employee retention credit.

The relationship between these requirements and practical business operations is straightforward: if your business faced genuine COVID-19 disruptions, whether through mandated closures or revenue losses, you likely have a path to claiming this valuable tax credit. The specific eligibility pathway depends on your circumstances, which we explore in detail below.

ERC Program Eligibility and Credit Calculations

Building on the core requirements, understanding the specific eligibility scenarios and how they affect your credit calculation is essential for maximizing your ERC benefit. Employer’s gross receipts are used as a benchmark for eligibility, and all income—including donations and grants—are included in this calculation. The rules differ substantially between 2020 and 2021, and employer size significantly impacts which wages qualify.

Business Operation Disruption and Decline in Gross Receipts Requirements

Employers could qualify through one of two primary pathways, each with distinct documentation requirements:

Full or partial suspension of operations: This pathway applies when a government order from a federal, state, or local authority limited commerce, travel, or group meetings due to COVID-19. The employer is eligible if there was an order from the government to limit commerce, travel, or group meetings that resulted in the employer’s partial or full suspension of operations. A business is considered partially suspended when a portion of its operations cannot occur—for example, a restaurant that could operate takeout but not dine-in service. Essential businesses that remained open might still qualify if specific aspects of their employer’s operations were restricted. Only governmental orders and mandatory requirements qualify for the Employee Retention Credit; recommendations and suggestions do not qualify.

Significant decline in gross receipts: This pathway uses measurable revenue thresholds:

• 2020: Employer’s gross receipts fell below 50% of the same quarter in 2019. Eligibility continued until receipts exceeded 80% of the corresponding quarter in 2019.
• 2021: Employer’s gross receipts fell below 80% of the same quarter in 2019 (a 20% decline threshold). An alternative quarter election allowed using the preceding quarter’s receipts for comparison.

Recovery startup business provisions: The American Rescue Plan Act created this category for entities that began operations after February 15, 2020, with average annual gross receipts not exceeding $1 million. These businesses could claim the credit for the third or fourth quarters of 2021, but faced a cap of $50,000 in total credit per quarter across all employees.

Employee Size Classifications and Impact

Employee count thresholds determine which wages qualify as qualified wages paid, creating significantly different outcomes for small versus large employers:

2020 Rules (100-employee threshold):

• Employers with 100 or fewer full-time employees in 2019 could count all wages paid to employees during eligible quarters, regardless of whether employees were actively working.
• Employers with more than 100 full-time employees could only count wages paid to employees who were not providing services due to suspension or decline conditions.

2021 Rules (500-employee threshold):

• Employers with 500 or fewer full-time employees in 2019 could count all wages paid during eligible quarters.
• Employers with more than 500 full-time employees could only count wages for employees not providing services, unless they qualified as “severely financially distressed” (gross receipts decline exceeding 90%).

Full-time employee status follows the Internal Revenue Code Section 4980H definition: approximately 30 hours per week or 130 hours per month. Aggregation rules apply—related entities under common control must be counted together when determining employer size.

Qualified Wages and Credit Amount Calculations

The calculation methodology differs substantially between program years:

Example: An employer paid $8,000 per quarter to an employee across Q1, Q2, and Q3 of 2021. The credit equals 70% × $8,000 × 3 quarters = $16,800 per employee.

For recovery startup businesses, the calculation follows 2021 rules but cannot exceed $50,000 per quarter across all employees. This means a startup with 10 employees would hit the cap even though individual calculations might suggest a higher amount.

Qualified health plan expenses—employer contributions to group health plans allocable to qualified wages—add to the wage amounts subject to these calculations, increasing the potential credit.

Special Considerations for PEO Client Employers

Reconciling ERC Claims When Using a PEO

For businesses that partner with a Professional Employer Organization (PEO) or Certified Professional Employer Organization (CPEO), claiming the Employee Retention Credit (ERC) involves a few additional steps and considerations compared to traditional employers. The ERC, as a refundable tax credit, was designed to help eligible employers—including those using PEOs—retain employees during the COVID-19 pandemic by offsetting employment tax liabilities.

Understanding ERC Eligibility with a PEO:

PEO client employers must first determine their eligibility for the employee retention credit by assessing whether they experienced a full or partial suspension of operations due to a government order, or a significant decline in gross receipts compared to the same calendar quarter in 2019. This eligibility assessment is the responsibility of the client employer, not the PEO, and should be based on the client’s specific business operations and financial data.

Calculating Qualified Wages Paid:

Once eligibility is established, PEO client employers need to identify the qualified wages paid to employees during eligible quarters. This includes not only regular wages subject to Social Security tax but also qualified health plan expenses. Businesses cannot use the same wages for both the ERC and other relief programs, such as the Paycheck Protection Program (PPP). Your business must carefully allocate wages, especially if you received a PPP loan, to ensure wages used for PPP loan forgiveness do not also count as qualified wages for the ERC.

Reporting and Reconciling ERC Claims:

PEOs typically file aggregate quarterly employment tax returns (Form 941) on behalf of their client employers. However, the Internal Revenue Service (IRS) requires that ERC claims be properly allocated and reported for each client employer. This means that PEO clients must provide their PEO with accurate information about their qualified wages, gross receipts, and any government orders affecting their operations. The PEO will then report the ERC on the client’s behalf, ensuring that the credit is applied against the client’s share of employment taxes.

If the refundable tax credit exceeds the employment taxes due, the excess can be refunded to the client employer. In some cases, advance payments may be requested using Form 7200, though this is less common now that the program has ended for new wage periods.

Legislative Updates and IRS Scrutiny:

The Infrastructure Investment and Jobs Act brought significant changes to the ERC program, including the early sunset of the credit for most employers after the third quarter of 2021. However, recovery startup businesses—those that began operations after February 15, 2020, and meet certain gross receipts thresholds—may still claim the ERC for qualified wages paid in the third and fourth quarters of 2021. PEO client employers should review their status to determine if they qualify as a recovery startup and ensure their ERC claims reflect the latest legislative updates.

Given the IRS’s increased focus on preventing fraudulent ERC claims, PEO client employers must maintain thorough documentation supporting their eligibility, calculations of qualified wages paid, and the allocation of wages between the ERC and PPP loan forgiveness. The IRS announced enhanced review procedures and created a settlement program for businesses that may have misunderstood their eligibility, making compliance and accurate record-keeping more important than ever.

How to Apply for the ERC Program

With eligibility and calculations understood, the application process to claim the employee retention credit becomes straightforward. Most businesses seeking the employee retention credit today will claim the employee retention credit by filing amended returns, as the program’s eligible quarters have closed for original quarterly employment tax returns. Employers can file for the Employee Retention Credit retroactively by amending their 2020 or 2021 tax returns.

Eligible employers report the total qualified wages and health insurance costs on their quarterly employment tax returns, typically using Form 941. If a business needs to request a tax credit refund for previously filed quarters, they can file Form 941-X with the IRS. Employers must file amended returns for any quarter ending in 2021 no later than April 15, 2025, to claim the Employee Retention Credit. Employers can still claim the Employee Retention Credit for wages paid during the pandemic, but must ensure these wages were not counted for other credits.

Step-by-Step Application Process

The filing process requires careful documentation and precise calculations. Here’s how to claim the credit effectively:

Step 1: Gather qualifying wage and health plan expense documentation

Compile payroll records showing wages paid each quarter, employer-paid health plan expense documentation, gross receipts by quarter for 2019 and 2020/2021, copies of government orders affecting your business, and records of any PPP loan amounts and how forgiveness was calculated. This documentation must support your eligibility pathway.

Step 2: Calculate eligible quarters and credit amounts

Determine which quarters your business met either the suspension test or gross receipts test. Apply the correct employee size threshold (100 for 2020, 500 for 2021) to identify which wages qualify. Calculate qualified wages per employee, including health plan expenses, while excluding any wages used for PPP forgiveness. Apply the appropriate credit percentage and caps.

Step 3: File Form 941 or Form 941-X for each qualifying quarter

For past quarters, file Form 941-X (adjusted employment tax return) for each quarter where you’re claiming or modifying the credit. Follow current Internal Revenue Service instructions, which now permit electronic filing for many amended returns. Each quarter requires a separate form.

Step 4: Track refund processing and maintain records

Processing times vary significantly due to IRS backlogs and fraud prevention measures. Maintain all supporting documentation for at least four years or the applicable audit period. The IRS has announced enhanced scrutiny of ERC claims, making thorough documentation essential.

Filing Options Comparison

Factor	Original Form 941	Amended Form 941-X
When to Use	Current quarter filing	Past quarters requiring correction
Timing	By quarterly deadline	Within statute of limitations
Processing	Standard payroll processing	Longer processing times (often 6-12+ months)
Documentation	Standard payroll records	Enhanced documentation recommended
Current Availability	Not applicable (program ended)	Available for eligible past quarters

For most businesses in 2025 or later, the adjusted employment tax return route via Form 941-X is the only option, as original filing deadlines for all eligible quarters have passed.

Common ERC Program Challenges and Solutions

Businesses frequently encounter specific obstacles when pursuing ERC claims. Understanding these challenges and their solutions can prevent costly errors and delays.

Paycheck Protection Program (PPP) Loan Coordination Issues

Many employers who received PPP loans struggle with the prohibition against using the same wages for both PPP forgiveness and ERC. The solution involves strategic wage allocation: maximize non-payroll eligible costs (rent, utilities, covered operations expenditures) in your PPP forgiveness application, reserving payroll costs for the employee retention credit where possible.

If you’ve already received PPP forgiveness using primarily payroll costs, you can still claim ERC on wages that exceeded your forgiveness amount. A qualified tax preparer can help model optimal allocations that maximize combined benefits without violating the double-dipping prohibition.

Calculation and Eligibility Confusion

The evolving rules between 2020 and 2021—different credit percentages, employee thresholds, and wage caps—lead to frequent calculation errors. Self employed individuals sometimes incorrectly assume they qualify for wages paid to themselves.

The solution involves consulting IRS Notice 2021-20 and Notice 2021-49 for authoritative guidance, using worksheets that track each employee’s wages by quarter against applicable caps, and engaging a qualified professional for complex situations. The Internal Revenue Service provides extensive FAQ resources addressing common eligibility requirements questions.

Conclusion and Next Steps

The Employee Retention Credit represents a significant opportunity for eligible employers to recover substantial funds—potentially tens of thousands of dollars per employee—for wages paid during COVID-19 disruptions. While the program has ended for new wage payments, certain eligible businesses can still file amended returns for past quarters through 2025 or 2027, depending on the quarter in question.

Immediate actionable steps:

1. Assess eligibility by reviewing each quarter from Q2 2020 through Q3 2021 (Q4 2021 for recovery startups) against suspension and gross receipts tests
2. Gather documentation including payroll records, financial statements, government orders, and PPP forgiveness records
3. Calculate potential credits using the correct rates and caps for each program year
4. Consult qualified professionals given IRS scrutiny and complexity of coordination rules
5. File claims promptly to meet remaining deadlines and allow for processing time

Frequently Asked Questions

Can I still apply for the ERC program in 2026?

You cannot apply for the ERC program for new wage periods, as the program ended December 31, 2021. However, you can still file amended returns (Form 941-X) for past eligible quarters within statute of limitations deadlines. The deadline for Q1-Q2 2021 is April 15, 2025. For Q3-Q4 2021 (recovery startups only), the deadline extends to April 15, 2027. All 2020 quarter deadlines have passed as of April 15, 2024.

What is the maximum ERC amount my business can receive per employee?

The maximum employee retention credit per employee totals $26,000 when combining 2020 and 2021 maximums ($5,000 for 2020 plus $21,000 for Q1-Q3 2021). If your business also qualified as a recovery startup business for Q4 2021, the theoretical maximum reaches $28,000, though the $50,000 quarterly cap for recovery startups limits total claims regardless of employee count.

Can I claim both PPP forgiveness and ERC for my business?

Yes, you can claim both programs, but you cannot use the same wages for both. Wages used to obtain PPP loan forgiveness cannot also count as qualified wages for the employee retention credit. You must allocate wages between programs—any dollar of wages can only go toward one benefit. Strategic allocation typically involves maximizing non-payroll costs for PPP forgiveness to preserve more wages for ERC.

How long does it take to receive ERC refunds from the IRS?

Processing times for Form 941-X refunds currently range from several months to over a year. The IRS has experienced significant backlogs due to the volume of ERC claims and has implemented enhanced fraud prevention reviews. Businesses should maintain complete documentation and expect extended waits. The IRS announced processing improvements, but delays remain common.

What happens if the IRS audits my ERC claim?

IRS audits focus on verifying eligibility by reviewing suspension documentation, gross receipts calculations, qualified wage allocations, employee count classifications, and recovery startup business qualifications. Auditors also confirm that businesses did not double-count qualified wages with PPP or other credits. If the IRS finds overclaims during an audit, businesses may need to repay the credit with interest and potentially face penalties. Maintaining thorough, contemporaneous documentation significantly reduces audit risk and strengthens your position during an examination.

Do I need to reduce my wage deductions on tax returns if I claim ERC?

Yes. You cannot also deduct the wages used to calculate your employee retention credit claimed amount as a business expense on your income tax returns. You must reduce your wage deduction by the amount of credit received to prevent a double tax benefit. Businesses typically make this adjustment on the tax year return corresponding to when they claimed the credit, and they may need to file amended income tax returns if they already filed.
