IRS Enforcement in 2026 Valuation Focus, Audit Triggers, and Preparation

A Shifting Enforcement Landscape

The Internal Revenue Service is undergoing a significant transformation in 2026. While the agency grapples with workforce reductions and leadership turnover, it is simultaneously sharpening its focus on specific areas of non-compliance . For businesses and individuals, understanding these shifting priorities is essential for effective tax planning and risk management.

This article examines the current audit trends, common triggers, and practical strategies for staying compliant. We will explore how the IRS is using data analytics and specialized guides to identify potential issues, and what you can do to prepare.

The Rise of Valuation Audits

One of the most notable trends in 2026 is the IRS’s renewed focus on valuation issues, particularly in charitable donations and tax credit claims . Tax practitioners have observed a rise in new audits centered on how assets are valued, not just in non-cash donations but also in energy projects that qualify for investment tax credits.

According to tax attorney Daniel Strickland, “It all comes back to issues that the IRS is identifying in valuation – maybe we’ll call it aggressive valuation” . This focus follows the agency’s continued crackdown on syndicated conservation easement shelters, a strategy where partnerships take large charitable deductions for donated land.

For taxpayers, this means that any transaction involving significant valuation estimates—whether donating art, medical devices, or claiming energy credits—faces heightened scrutiny. Proper documentation and independent appraisals are more critical than ever.

Understanding IRS Audit Technique Guides (ATGs)

The IRS develops Audit Technique Guides (ATGs) and Technical Guides (TGs) to train its examiners on specific industries and issues . While these guides are designed for IRS employees, they offer valuable insight for taxpayers and practitioners.

For exempt organizations, the IRS has published guides covering topics like:

  • Public charities

  • Private foundations

  • Inurement and private benefit

  • Unrelated business income

  • Foundation classification 

These guides explain specialized business practices, explore common issues, and provide relevant legal authority. For nonprofits in Virginia and DC, reviewing the applicable guides can help identify areas of risk before an audit occurs.

Similarly, the Capitalization of Tangible Property Audit Technique Guide provides detailed guidance on how the IRS examines depreciation, cost segregation studies, and property improvement rules . Businesses making significant capital investments should be familiar with these rules to ensure proper treatment.

Common Audit Triggers

Based on IRS priorities and practitioner observations, certain red flags are more likely to draw attention in 2026:

For Individuals:

  • Large charitable deductions with questionable valuations

  • Significant investment income with complex structuring

  • Inconsistencies between reported income and lifestyle indicators

For Businesses:

  • Aggressive valuation of assets or credits

  • Misclassification of workers (employees vs. independent contractors)

  • Unreported income or excessive deductions relative to industry norms

  • Complex related-party transactions

For Nonprofits:

  • Excessive compensation to officers or insiders

  • Private benefit or inurement issues

  • Inaccurate reporting on Form 990

  • Unrelated business income that is not properly allocated

The Role of Statistical Sampling in Audits

The IRS uses statistical sampling techniques to conduct audits efficiently, particularly for populations of transactions . The agency’s Internal Revenue Manual (IRM) outlines detailed procedures for determining proposed population adjustments.

Under these rules, the IRS generally uses a 95% confidence level and a 90% two-sided confidence interval to project sample results to the entire population . If the relative sampling error is 10% or less, the IRS may use the point estimate of the adjustment directly. This means that even if only a sample of transactions is examined, the findings can be extrapolated to the entire population.

For taxpayers, this underscores the importance of maintaining accurate records for all transactions. If a sample reveals errors, the IRS can project those errors across the entire population.

Preparing for an Audit

Given the current environment, proactive preparation is more important than ever.

1. Maintain Robust Documentation
Every deduction, credit, and valuation should be supported by clear, contemporaneous documentation. For non-cash donations, independent appraisals are essential. For business expenses, receipts and logs are critical.

2. Review IRS Guides for Your Industry
If you operate in a sector with a published Audit Technique Guide, review it. These guides reveal what examiners look for and how they analyze issues .

3. Conduct Internal Reviews
Periodically review your tax positions as if you were an auditor. Identify areas of potential risk and address them before the IRS does.

4. Work with a Qualified Professional
An experienced CPA can help you navigate complex tax issues, prepare for potential scrutiny, and represent you if an audit occurs. At Nova Tax & Accounting Services , our team provides audit representation and tax resolution services for individuals, businesses, and nonprofits.
