A wage earner in Dallas who reports $85,000 on a W-2 and claims the standard deduction has, statistically, almost no chance of sitting across from an IRS examiner this year. A hedge-fund partner in Greenwich pulling seven figures through a web of K-1s faces odds roughly eight times higher. That contrast, already stark, is on track to widen further: based on trends in the IRS’s published Data Book examination tables, filers earning over $1 million can expect an audit rate of about 1 in 38 for tax year 2026, while households under $200,000 face roughly 1 in 313, the lowest examination rate ever recorded for that group.
The gap between those two numbers is the widest in at least a decade, and it is not accidental. It reflects a deliberate reallocation of IRS enforcement resources: away from straightforward wage-earner returns and toward high-wealth individuals, large partnerships, and complex business structures the agency believes harbor billions in uncollected taxes each year.
Where the numbers come from
Each fiscal year, the IRS releases its Data Book, a granular accounting of how many returns the agency examines and what share of total filings that represents. The critical table for audit-rate tracking is Table 17, which breaks out examination coverage by return type and income bracket. The most recent revision of that table updated how certain examination categories are counted, and it is the version tax researchers now use as their baseline.
The pattern in those figures is unmistakable. Over the past decade, audit rates for returns under $200,000 have fallen steadily as budget cuts shrank the IRS enforcement workforce even while the total number of individual filings grew. Examination rates for millionaire filers also dropped sharply during those austerity years, but they have begun climbing again as new funding reaches the agency.
Independent oversight supports the trend. A Government Accountability Office review (GAO-22-104960) documented the long decline in middle-income audits and tied it directly to staffing losses in IRS examination divisions. The Treasury Inspector General for Tax Administration (TIGTA) has separately tracked how the agency is deploying Inflation Reduction Act dollars to rebuild capacity for complex, high-income cases.
The 1-in-38 and 1-in-313 ratios cited here are extrapolations from those published trends, current staffing plans, and the agency’s stated enforcement priorities. They are not final measurements. Returns filed for tax year 2026 are only now entering the IRS processing pipeline, and actual examination counts will not be published until the corresponding Data Book appears, typically 12 to 18 months after the close of the fiscal year.
Why the shift is happening now
The Inflation Reduction Act, signed in August 2022, originally allocated roughly $80 billion to the IRS over a decade, with a large share earmarked for enforcement. Congress has since clawed back approximately $20 billion of that total through the Fiscal Responsibility Act of 2023 and subsequent budget negotiations, leaving an effective allocation closer to $58 billion to $60 billion. Even the reduced figure represents the largest sustained investment in IRS capacity in a generation.
The agency’s Strategic Operating Plan, released in response to the IRA, laid out a roadmap for directing new resources toward taxpayers earning above $400,000, large corporations, and opaque partnership structures where the IRS estimated the annual tax gap runs into the tens of billions. A central promise accompanied that plan: the agency would not use the new funding to raise audit rates on households earning less than $400,000. That commitment, echoed by President Biden during his February 2023 State of the Union address, effectively locked in the downward trajectory for middle-income examinations while pushing high-income audit rates upward.
Early results have been concrete. In February 2024, the IRS announced it had collected more than $500 million from roughly 1,600 millionaire non-filers, people who earned seven figures but simply never submitted a return. The agency has also launched enforcement initiatives targeting syndicated conservation easements, micro-captive insurance arrangements, and unreported income from digital assets and offshore accounts. Expanded use of data analytics now allows examiners to prioritize returns where the potential revenue recovery is largest.
What could change the picture
Several forces could push these numbers in either direction before 2026 audit statistics are finalized.
The most immediate is funding. The IRA’s enforcement allocation has been a recurring target in congressional budget talks, and further rescissions remain possible. If cuts go deep enough, the IRS would likely have to scale back the resource-intensive audits of high-wealth returns that drive the current gap. That would narrow the disparity not by auditing more middle-income filers but by auditing fewer wealthy ones.
Political transitions add another layer of uncertainty. The enforcement priorities set under one administration can be revised by the next. The current policy environment, shaped by commitments made in 2022 and 2023, may not survive intact through the full ramp-up period the IRS originally envisioned. The Trump administration, which took office in January 2025, has signaled interest in restructuring IRS operations, and any significant shift in enforcement philosophy could alter the trajectory for high-income audits.
There is also a measurement nuance worth flagging. The $400,000 income threshold in the IRS’s enforcement pledge does not align neatly with the income bands used in Data Book reporting. Filers earning between $200,000 and $400,000 sometimes appear in the same statistical categories as much higher earners, making it difficult to verify precisely how audit exposure has shifted for every segment of the upper-middle-income range.
What this means if you file under $200,000
For the vast majority of American households, the practical takeaway is simple: the odds of a traditional IRS audit are lower than they have ever been. That does not mean the agency has stopped watching. The IRS still runs millions of automated checks each year, and certain red flags, such as large discrepancies between reported income and third-party documents like W-2s and 1099s, unreported foreign accounts, or deductions that look outsized relative to income, continue to trigger correspondence inquiries regardless of what a filer earns.
One notable exception to the low-audit-rate story involves the Earned Income Tax Credit. EITC claimants, many of whom earn well under $50,000, have historically faced audit rates near or above 1%, driven largely by automated correspondence audits flagging potential overclaims. That rate has drawn criticism from lawmakers and advocacy groups who argue it places a disproportionate compliance burden on low-income families. The IRS has acknowledged the concern and pledged to reduce EITC audit disparities, but the most recent data still shows elevated examination activity for those returns.
For high earners, the calculus runs the other direction. Filers above $1 million, and especially those above $5 million or $10 million, are seeing audit rates climb back toward levels not seen since before the budget sequestration of the early 2010s. The IRS has been particularly aggressive in pursuing cases involving complex pass-through structures, where income can be difficult to trace and where the agency believes significant revenue is at stake.
How the gap compares to a decade ago
To appreciate how unusual the current disparity is, consider where things stood in fiscal year 2010, the recent high-water mark for IRS enforcement. The overall individual audit rate that year was about 1.1%, but the averages masked enormous variation. Millionaire filers faced examination odds above 8%. Returns under $200,000 were audited at rates closer to 0.7% to 0.9%, depending on the income band. The ratio between the top and bottom was significant, but nothing like the gulf visible today.
Budget sequestration and repeated funding cuts then hollowed out the enforcement division. By the late 2010s, audit rates had collapsed across the board. Millionaire examination rates fell below 1% in some years. Middle-income rates dropped further still. The IRA funding reversed the decline for high earners but did not restore broad-based enforcement, producing a two-track system: intensive scrutiny at the top of the income distribution and minimal contact everywhere else.
Whether that represents sound tax policy or a structural weakness in voluntary compliance is a question that divides tax professionals, former IRS officials, and researchers. What is not in dispute is the scale of the gap itself, or the fact that for most American households filing a straightforward return in 2026, an IRS audit is about as likely as being struck by lightning twice in the same year.
