Lowest-income filers were audited nearly 3 times as often as everyone else, according to latest IRS data

Most people assume the IRS spends most audit energy chasing wealthy taxpayers. But the agency's own GAO review shows a recurring exception: Low-income filers who claim the Earned Income Tax Credit (EITC) face disproportionate audit attention. If you're trying to lower your financial stress, that can turn a valuable refund into months of mail, records, and waiting. The details tell a more complicated story.

Here's what the numbers show, and why they matter now.

EITC explained

The EITC is one of the country's major tax benefits for low- and moderate-income workers. The IRS says about 24 million eligible workers and families received roughly $70 billion from the credit in 2025.

Yet IRS audit data show EITC returns draw more attention than individual returns overall. In the IRS's latest Data Book, tax year 2022 returns claiming the EITC had 0.8% examination coverage, compared with 0.3% for all individual income tax returns. That's not a huge percentage on its face, but it still means these filers were audited several times as often as the average individual taxpayer.

The credit is helpful, but complicated

The EITC can be valuable because it can reduce taxes owed and may generate a refund for eligible workers. The EITC and Child Tax Credit have helped lift millions of people out of poverty, including children, and made millions less poor. That's why the credit matters beyond tax season.

But eligibility can be hard to understand. Income, filing status, qualifying children, residency, relationship tests, and investment income rules all matter. When life is messy — shared custody, changing jobs, moving in with relatives, or inconsistent records — mistakes can happen even when someone is trying to file correctly.

Most EITC audits happen through the mail

For many people, the word "audit" brings to mind an IRS agent sitting across the table. That is usually not what happens with EITC audits. The IRS Data Book shows that in fiscal year 2025, 92,817 of 93,857 closed EITC examinations were correspondence audits, meaning they were handled by mail.

That is nearly all of them. Mail audits are cheaper and easier for the IRS to conduct, but they can be hard for taxpayers who don't understand the notice, move frequently, lack records, or can't get help quickly. A missed deadline or incomplete response can change the result.

Paperwork problems can cost families real money

A correspondence audit often asks taxpayers to prove eligibility. That may mean sending school records, medical records, lease documents, child care records, or other proof that a qualifying child lived with them for the required period. For retirees helping adult children or grandchildren, those household details can be more complicated than they look.

Research published through Stanford's Institute for Economic Policy Research noted that audits can intensify financial strain, freeze refunds, and may discourage participation in programs that help lower-income taxpayers. The problem is not only whether a filer was eligible. It's whether they can prove eligibility in the exact way the IRS asks, by the deadline listed in the letter.

Higher-income audits tell a different story

GAO found that audit rates fell across income levels from tax year 2010 to tax year 2019, but the biggest declines happened among higher-income taxpayers with incomes of $200,000 and above. The same report said lower-income audits are generally more automated, while audits of higher-income taxpayers tend to involve more complex issues. That means audit rates alone don't tell the whole story.

GAO also found that recommended additional tax generally rose with taxpayer income. In other words, high-income audits can involve more resources, but they may also uncover more dollars per audit. That's part of the equity question raised by the data: which taxpayers get audited, how difficult those audits are, and how much revenue they actually produce.

Racial-disparity research adds another layer

Stanford also found that Black taxpayers were audited at 2.9 to 4.7 times the rate of non-Black taxpayers, even though the IRS does not collect taxpayer race. Researchers estimated race using other data and found that EITC-related audit selection explained much of the disparity. Specifically, it was found that selection within EITC claimants accounted for about 78% of the observed racial audit gap.

That finding should be handled carefully. The research does not say individual IRS employees targeted taxpayers by race. It does show that automated rules and audit-selection systems can produce uneven results when they focus heavily on certain types of returns.

Bottom line

The latest IRS data reinforce a pattern that can surprise many taxpayers: Some of the lowest-income filers, especially those claiming the EITC, face higher audit rates than the average individual filer. Could a tax credit meant to support working families become harder to use if eligible people fear the paperwork that comes with it?

For taxpayers, the practical takeaway is simple: Keep records before you need them. If you claim the EITC, save proof of income, residency, school enrollment, medical care, child care, and household relationships in one place. Respond quickly to IRS letters, and consider free help through the IRS Volunteer Income Tax Assistance program or a Low Income Taxpayer Clinic if you receive an audit notice. Good documentation can help you keep more of your money when a routine tax filing turns into something more stressful.
