Audit-Proofing Your Tax Credit Claims: Best Practices and Red Flags for 2026

The most recent IRS data illustrates the trend: in FY 2024, the IRS closed 505,514 audits and recommended over $29 billion in additional tax — signaling continued high enforcement levels as 2026 begins.

Meanwhile, pandemic-related programs continue to influence audit priorities. In 2024, the IRS announced plans to deny tens of thousands of improper Employee Retention Credit (ERC) claims after identifying high error risk.

And the National Taxpayer Advocate noted in early 2025 that ERC enforcement and processing delays remain significant issues in 2026.

For HR and Finance leaders, the message is clear: tax credit strategies must now be built on clean data, strong documentation, and consistent workflows that withstand examiner scrutiny.

Why 2026 Brings Greater Audit Risk

Tax incentives tied to hiring, wages, and workforce programs are under closer review for three reasons:

1. Increased IRS enforcement capacity
   Modernized systems and expanded staffing allow for deeper comparisons of payroll, tax returns, and credit claims.

2. Higher financial value of incentive programs
   Credits like WOTC, FICA tip credits, and state hiring incentives represent millions in annual savings for mid-sized employers.

3. Historical issues with pandemic-era programs

ERC errors heightened examiner sensitivity to wage-based incentives in general.

WOTC Still in Play Through 2025 — and Still Scrutinized

WOTC remains authorized through December 31, 2025, and many employers continue filing 2026 claims for prior-year certifications.

Recent IRS exam directives instruct auditors to review:

• Timeliness of Form 8850

• Certification accuracy

• Wage calculations

• Interaction with other credits

This makes WOTC workflows a central area of audit exposure entering 2026.

Red Flags That Trigger IRS or State Review

Audits often begin with routine data mismatches or missing documentation. 

In 2026, the most common triggers include:

1. ERC Claims Without Proper Support

IRS alerts issued throughout 2024–2025 warned against:

• Eligibility claims based solely on templates

• Misapplied governmental order rules

• Unsupported gross receipts calculations

Any employer with unresolved ERC claims should ensure a complete documentation file.

2. WOTC Documentation Gaps

Frequent issues include:

• Late Form 8850 submissions

• Missing demographic or pre-screening information

• Wages claimed outside certification windows

For full requirements, see the Form 8850 instructions.

3. Double-Counting Wages Across Programs

Improper wage stacking remains one of the fastest ways to trigger adjustments. Credits affected include:

• WOTC

• ERC

• FICA tip credits

• State hiring/training incentives

4. HR–Payroll–Tax Mismatches

Examiners cross-check:

• Forms 941

• Payroll registers

• Hiring data

• Credit worksheets

Mismatched employee start dates, wage totals, or headcounts raise immediate concern.

5. Lack of Documented Methodology

Even legitimate credits are at risk if the organization cannot explain:

• How eligibility was determined

• How wages were chosen

• How credits interact with other incentives

A defensible process is as important as a correct calculation.

Best Practices to Audit-Proof Your 2026 Tax Credit Claims

The following practices dramatically reduce audit exposure while improving accuracy and compliance.

1. Maintain a Centralized Credit Register

Track:

• Credits pursued

• Tax periods covered

• Methodology

• Supporting documentation

• Wage allocations

A single source of truth prevents inconsistencies between teams.

2. Standardize Documentation Requirements

Organize documentation by credit type, such as:

• WOTC: Form 8850, state certifications, payroll proof

• ERC: Gross receipts, government orders, payroll by quarter

• FICA Tip Credit: POS reports, FICA contributions

A structured document library shortens audit response time.

3. Integrate HR Workflows With Credit Requirements

Ensure onboarding and screening practices:

• Capture required demographic data

• Trigger timely WOTC submissions

• Feed structured information into payroll and finance systems

Consistent workflows reduce missed credits and errors.

4. Reconcile Wages Quarterly

Tie credit calculations to:

• Payroll registers

• Forms 941

• Year-end summaries

Quarterly reconciliation demonstrates internal control — a key factor in reducing audit depth.

5. Write Clear Methodology Summaries

Document:

• Eligibility logic

• Wage selection rules

• Coordination with other credits

These summaries give examiners immediate clarity and reduce the likelihood of prolonged review.

6. Use Technology to Eliminate Manual Risk

Modern credit platforms reduce human error and strengthen compliance by offering:

• Standardized logic

• Audit-ready audit trails

• Integrated documentation

• Real-time legislative updates

• Automated wage and eligibility checks
