The IRS flagged $6.2 trillion offshore. It collected $40 million.
Summary
A Treasury Inspector General audit found the IRS identified 405 taxpayers who appeared to be hiding foreign bank accounts from federal reporting requirements, with balances totaling nearly $6.2 trillion. The IRS examined just 12 of them. Five were assessed anything at all -- a combined $39.78 million, against nearly $683 million the IRS has spent administering the offshore-reporting law overall. The IRS disagrees that it should assess more penalties, or even measure whether the program works.
How 1,609 leads became 12 examinations
The 's Offshore Private Banking Campaign, known internally as Campaign 896, started with 1,609 taxpayers⧉ flagged for potentially failing to file Form 8938, the disclosure required under the Foreign Account Tax Compliance Act (FATCA) for large foreign financial holdings. After removing cases with data problems and taxpayers who turned out to be compliant, 405 remained -- with unreported account balances totaling nearly $6.2 trillion, a figure that includes three extreme outlier accounts worth almost $6 trillion on their own. Of those 405, 164 were referred for possible examination, including 122 the itself called 'egregious nonfilers.' Only 12 were actually examined. Campaign officials told auditors they had limited resources and competing priorities.

Letters instead of penalties
The 241 flagged taxpayers who weren't referred for examination -- each with an average unreported balance of $377 million -- got letters instead⧉: 225 educational letters requiring no response, and 16 soft letters requiring one. None were assessed the initial $10,000 FATCA nonfiling penalty, a fine that can grow to $60,000 with continued noncompliance. Of the 12 taxpayers who were examined, only 5 were assessed anything: $39.7 million in additional tax, plus $80,000 combined in Form 8938 and related nonfiling penalties. Most of the 12 examinations closed with no change at all -- worth noting, since it cuts against assuming the full 405 were deliberately evading taxes.
Campaign officials told auditors that assessing FATCA nonfiling penalties simply 'are not part of the campaign enforcement strategy' -- a deliberate choice, not an oversight. pushed back directly: the itself acknowledged during the review that a full examination isn't legally necessary to impose the FATCA penalty, meaning the agency could have assessed penalties through lighter-weight correspondence without the examination capacity it says it lacks. Separately, the report describes -- with some detail redacted -- a distinct category of potential nonfilers Campaign 896 excludes from its workstream entirely, one the report indicates represented 87% of potential nonfilers by count and 46% of total account balances in its own underlying data. The known gap this report documents likely understates the true one.

The bill for barely enforcing it
None of this comes cheap. The IRS has spent almost $683 million⧉ administering FATCA across all its activities since the law's implementation -- $109 million of that since 's last review in 2022. Auditors calculated separately that if the had simply assessed the initial $10,000 nonfiling penalty on the 393 taxpayers it never got around to examining, that alone would have brought in $3.93 million. It didn't happen. Meanwhile, the division responsible for administering FATCA, Large Business and International, lost 742 revenue agents during fiscal year 2025 amid broader workforce cuts -- a reduction whose effect on offshore enforcement says isn't yet known.
The IRS's defense: this is working as designed
made three recommendations. The disagreed with two of them. It declined to commit to assessing more FATCA penalties, telling auditors it needed 'sufficient review and consideration of relevant facts' before estimating what penalties would even be owed. It also rejected a recommendation to adopt performance measures that would let leadership judge whether the FATCA program is working at all, stating flatly that FATCA is 'a statutory reporting requirement' the agency doesn't treat differently from any other routine information-reporting rule. The did partially agree to study whether Form 1099 data could help identify more nonfilers -- with an implementation target of October 15, 2027.
The takeaway
- The isn't hiding the numbers -- it's just not acting on them. Every figure in this piece comes from the 's own campaign data, handed to its inspector general. The agency knows exactly who it flagged and how little it did about it.
- The blames resources for a problem it says it doesn't need resources to fix. Campaign officials cited limited examination capacity for skipping penalties on 393 nonfilers -- but notes the itself acknowledged an examination isn't legally required to assess the FATCA penalty. Campaign officials also told auditors penalty assessment simply 'are not part of the campaign enforcement strategy.'
- The argues it doesn't need to measure its own success. Rejecting a recommendation for FATCA performance metrics, the agency said the law gets no special treatment -- even after its own watchdog found a 405-taxpayer, $6.2 trillion enforcement gap.
The $6.2 trillion figure is the total unreported account balance identified, not unpaid tax -- account balances, unreported income, and tax actually owed are three different things, and the audit does not estimate the last of those for these 405 taxpayers. Three outlier accounts account for most of that $6.2 trillion; excluded them when calculating the more representative per-taxpayer averages cited elsewhere in this piece ($1.7 billion and $1.3 billion), which this piece preserves rather than blending. Separately, the $683 million total FATCA cost covers the 's entire FATCA compliance and reporting infrastructure, not Campaign 896 alone -- this piece presents it as context for scale, not as a direct campaign-specific cost-benefit ratio.

The has a law built to catch Americans hiding money offshore. A Treasury Inspector General audit⧉ found the agency's own enforcement campaign identified 405 taxpayers who appeared to have failed to report foreign bank accounts -- with balances totaling nearly $6.2 trillion. The examined 12 of them. (That $6.2 trillion is unreported account balances, not unpaid tax -- the audit doesn't estimate what these taxpayers actually owed.)
