IRS enforcement delays leave $696B in unpaid taxes uncollected
Summary
The IRS is struggling to enforce tax collection amid a significant backlog, as revealed by the Treasury Inspector General for Tax Administration, which found that Americans underpaid their taxes by an estimated $696 billion in 2022. This backlog was exacerbated by previous budget cuts in 2025 and a reduction of the IRS workforce by 28% during the Trump administration, resulting in resources being inadequate to pursue all delinquent filers. As of December 2025, nearly 34,000 high-income individuals, who were notified in early 2024 about their missing tax returns valued at approximately $15.7 billion, have not had their cases followed up by the IRS. Additionally, the inspector general highlighted inefficiencies, such as nearly 5,000 taxpayers receiving erroneous notices despite having filed their taxes.
