A new watchdog report puts a number on a category of taxpayer the IRS has spent years trying to reach: people whose income was reported to the agency by an employer or a bank, but who never actually filed a return. The Treasury Inspector General for Tax Administration counts 73.2 million such cases sitting in IRS inventory as of the end of fiscal year 2025, spanning five tax years. The count arrives as the agency’s free Direct File filing tool, once positioned as an alternative to commercial tax software, remains unavailable for a second consecutive filing season.
What TIGTA Means by 73.2 Million Nonfiler Cases
TIGTA reports that the IRS had identified 73.2 million potential individual nonfiler cases covering tax years 2019 through 2023, with 24 million of them, or 32%, tied to tax year 2023 alone. Each case represents a return the IRS expected but never received, matched against income a third party, such as an employer or bank, already reported to the agency.
TIGTA’s own framing treats the figure as an inventory count rather than a final bill: some of those 73.2 million people may ultimately owe nothing once deductions and credits are applied, and others may have cases that carried over from one year to the next while still unresolved. The count comes from Trends in Compliance Activities Through Fiscal Year 2025, released August 26, 2026.

A Separate, Narrower Review Shows Where Enforcement Has Stalled
A related but distinct TIGTA review, covered by the Journal of Accountancy on September 15, 2026, examined the IRS’s high-income nonfiler initiative, launched in February 2024 to monitor 135,270 cases involving taxpayers earning $400,000 or more, federal employees, and others flagged through a Senate Finance Committee request. Of the 111,566 cases TIGTA was able to analyze, 81,417, or 73%, still had neither a filed return nor a completed assessment as of June 30, 2025. The same report found that the IRS’s Nonfiler Executive Steering Committee has not met since September 2020, and concluded the agency lacks coordinated, agencywide oversight of its nonfiler programs generally, even as its own data puts the gross tax gap for tax year 2022 at $696 billion, with about $63 billion, or 9%, attributable to nonfilers specifically.
Together, the two reports describe an agency sitting on a large, well-quantified inventory of unfiled returns while its internal coordination for actually working that inventory has lagged for years. Neither report claims the IRS is about to contact all 73.2 million people at once; the figure functions as a scoreboard of what the agency’s own data says is outstanding, not a rollout schedule for enforcement letters.
Direct File’s Exit Leaves Fewer Free Filing Options
The enforcement push comes as one no-cost filing option has disappeared. According to Nextgov’s reporting on the IRS’s internal notice to 25 states, the agency confirmed in November 2025 that “IRS Direct File will not be available in Filing Season 2026” and that “no launch date has been set for the future.” Taxpayers who used the free government filing tool in 2024 or 2025 can no longer log in to retrieve past returns and are directed instead to their IRS online accounts. The remaining public-private Free File program has technically stayed available, but only about 3% of eligible taxpayers have used it in recent years, and it has its own history of drawing IRS and FTC scrutiny after a member company was found pushing customers toward paid products even when a free option applied to them. The 2025 tax and spending law directed the Treasury Department to study public-private alternatives to replace Direct File going forward, though no successor has launched.
For someone who has fallen behind on filing, the combination is not encouraging: a larger, better-documented nonfiler inventory on one side, and one fewer free way to get current on the other.
When the IRS goes looking for a return
A taxpayer who is years behind on filing, or who simply isn’t sure whether the IRS counts them among these cases, has fewer free options now that Direct File is gone and enforcement attention on unfiled returns is rising. Sorting out what the IRS actually has on record, and what any notice tied to these initiatives means, starts with the same basic tools the agency itself relies on: transcripts, notice codes, and a clear read on what a specific form is asking for.
