For years, a low-income family claiming the Earned Income Tax Credit has had a higher chance of being audited than a household earning over a million dollars. That isn’t a glitch in enforcement priorities — it’s a direct consequence of how the IRS is funded, staffed, and politically constrained. Auditing a working-class filer is fast, cheap, and unopposed. Auditing a wealthy filer is slow, expensive, and pushes back. Resources flow to the easier target.
The audit gap is documented in the IRS’s own data
Studies using Treasury and IRS records have repeatedly shown that EITC recipients — overwhelmingly low-income workers — are audited at rates comparable to or exceeding those of the top 1 percent. The gap narrowed somewhat after 2022 funding increases earmarked for high-income enforcement, but the historical pattern is clear and was confirmed by the Government Accountability Office. The agency itself has acknowledged the imbalance in congressional testimony.
Auditing the wealthy is operationally difficult
A complex high-net-worth return can include partnerships, trusts, foreign holdings, opaque business structures, and aggressive tax positions backed by expensive counsel. A single audit can take years and require senior agents with specialized training. The IRS has been steadily losing those agents — attrition at experienced levels has outpaced replacement for over a decade. Auditing an EITC return, by contrast, is largely automated correspondence: a letter requesting documentation of a child’s residency or earned income, processed by lower-graded staff. The cost-per-audit math pushes the agency toward the easy lane.
Political pressure shaped the imbalance
Congressional funding cuts to the IRS through the 2010s gutted the enforcement division specifically. The audit rate on millionaires dropped by more than 70 percent in roughly a decade. The audit rate on EITC filers held relatively steady because correspondence audits don’t require the same staffing. Wealthy taxpayers have organized representation; EITC recipients don’t. The political economy of enforcement made the regressive pattern almost inevitable. The 2022 Inflation Reduction Act allocated funds specifically to reverse this, but staffing and training take years to rebuild, and subsequent funding rescissions have clawed some of that back.
The cost-benefit framing favors the wealthy
A complicated audit of a high-income filer can recover hundreds of thousands or millions in unpaid tax. An EITC audit might claw back a few thousand. By any rational return-on-effort calculation, the agency should be auditing the rich more — and would, if it had the staffing and the political backing. Internal IRS analyses show this. The mismatch between what the data recommends and what enforcement actually looks like is a story about institutional capacity and political pressure, not about where the actual fraud lives.
The bottom line
The IRS isn’t biased against poor filers in some moral sense — it’s responding to the resources and constraints it has. Correspondence audits of low-income workers are cheap and uncontested. Audits of complex wealthy returns are expensive and contested. The pattern that emerges is regressive enforcement, and reversing it requires sustained funding, experienced staffing, and political tolerance for auditing people who can afford lawyers. Each of those has been in short supply for a long time.
