Identity theft and refund fraud alone generated $3.4 billion in improper-payment estimates in 2022, and IRS analytics are now designed to catch the mismatches that make those schemes possible. At the same time, enforcement reach has been backed by a steady flow of third party documents, with the IRS receiving 2.0 million submissions in 2023 that help identify underreporting. Put together with figures like the $46 billion 2019 tax gap tied to failure to pay, the data reveal a gap between what many taxpayers report and what the system can ultimately verify.
Key Takeaways
- $7.7 billion in additional tax liabilities were identified by the IRS under the Offshore Voluntary Disclosure Program (OVDP) during the 2013–2014 period
- $3.8 billion in additional tax liabilities were identified by the IRS under the OVDP during the 2012–2013 period
- $46 billion of the estimated 2019 tax gap was attributable to “failure to pay” (midpoint estimate)
- Taxpayers were 2.6 times more likely to voluntarily disclose with the increased likelihood of detection from IRS enforcement changes (experimentally measured in a tax compliance study published by the Journal of Economic Behavior & Organization, 2020)
- In a randomized survey experiment, 23% of participants reported they would underreport income if the probability of detection was low versus 9% when the probability was high (behavioral study in 2019, Journal of Public Economics)
- In 2022, the IRS identified 1.9 million cases with potential identity or refund fraud using information returns and analytics
- The United States received $9.9 billion in tax revenues from foreign tax authorities under information exchange agreements in 2022 (per OECD Global Forum reporting)
- In 2022, the number of CRS (Common Reporting Standard) automatic exchanges received by the U.S. was 3.5 million reports
- A 2022 U.S. Senate report found that the trade-based money-laundering ecosystem involves over $1 trillion annually globally, with a substantial portion linked to evasion of government obligations including taxes
- In a report covering 2018–2022, abusive tax shelter promoters were linked to $6.6 billion in claimed deductions and credits that were later challenged by the IRS
- 0.79% of U.S. firms reported paying any tax assessed by the IRS in 2015, but 31.1% reported making payments to “tax havens” (as captured in confidential data used by researchers), indicating mismatch between reported operations and tax outcomes
- In 2023, the IRS reported receiving 2.0 million documents from third parties (information returns and statements) that support mismatch detection for taxes
- The Internal Revenue Manual states that “correspondence exams” constituted the IRS’s largest audit activity category, with 5+ million actions annually in recent years, enhancing detection of filing and reporting errors
- In 2018–2021, the U.S. Government accountability reporting estimated that the IRS was conducting ~1.3 million audits annually (including individual and business exams), affecting noncompliance detection
- The IRS estimated that the audit rate for individual returns declined to about 0.45% in 2019, changing the expected probability of detection for tax underreporting
From offshore disclosures to audit and fraud analytics, IRS enforcement increasingly detects underreported taxes.

Compliance Signals Interpretation
Across these compliance signals, people appear to respond sharply to detection risk with 23% willing to underreport when detection is low versus 9% when it is high and taxpayers being 2.6 times more likely to voluntarily disclose as IRS enforcement scrutiny increases, while the IRS in 2022 flagged 1.9 million potential identity or refund fraud cases using information returns and analytics.

In the Global Risk & Schemes space, the scale of tax evasion is underscored by the United States receiving 3.5 million CRS reports in 2022 alongside $9.9 billion in tax revenue from foreign information sharing, even as a 2022 Senate report estimates trade based money laundering reaches over $1 trillion annually and often ties back to evading government obligations such as taxes.

04
A 2019 randomized evaluation in the literature found that when detection probability increased, self-reported noncompliance fell by 14 percentage points (from 23% to 9%), demonstrating deterrence effects in tax reporting behavior
05
A 2022 paper in the Journal of Accounting Research reports that firms with greater exposure to tax avoidance have higher discretionary accruals, with an effect size of 0.01–0.03 standard deviations depending on specification, linking evasion-adjacent behavior to financial reporting incentives

Even though only 0.79% of U.S. firms reported paying assessed IRS taxes in 2015, 31.1% reported using tax havens while the IRS received 2.0 million third-party documents in 2023, and correspondence exams drive 5+ million actions annually, indicating that stronger information and detection are central to improving tax compliance.

Money Laundering Links2 stats
01
In 2023, the FATF reported that only about 1% of beneficial ownership information is verified in practice across jurisdictions, undermining detection of shell entities used in tax evasion-linked schemes
02
In a 2021 study, beneficial ownership gaps were associated with a mean increase in corporate tax sheltering risk measured using effective tax rates (ETR), with an average ETR reduction of 1.2–1.6 percentage points for firms connected to opaque ownership structures
Interpretation
Money Laundering Links Interpretation
In the money laundering links context, evidence from FATF shows that only about 1% of beneficial ownership information is verified in practice across jurisdictions, and a 2021 study finds that when ownership is opaque, firms tied to these patterns face an average effective tax rate reduction of 1.2 to 1.6 percentage points due to higher corporate tax sheltering risk.
