The Internal Revenue Service's (IRS) longstanding requirement for taxpayers to declare income from unlawful activities, including drug dealing and stolen property, has recently reignited discussions on social media.

This peculiar stipulation, outlined in the IRS Publication 525, mandates that individuals must include in their tax returns the fair market value (FMV) of any stolen property in the year it's acquired, unless returned to its rightful owner within the same timeframe. Similarly, earnings from illegal enterprises must be reported as income, aligning with the broader principle that all income, irrespective of its source, is subject to taxation.

IRS website writes: "Illegal activities. Income from illegal activities, such as money from dealing illegal drugs, must be included in your income on Schedule 1 (Form 1040), line 8z, or on Schedule C (Form 1040) if from your self-employment activity." 

The directive, although longstanding and reminiscent of policies dating back to the Revenue Act of 1921, has spurred a mix of amusement and disbelief among social media users. A notable post on X, capturing over 6.8 million views, humorously reminded followers of this obligation, underscoring the surreal notion of self-reporting illicit gains to the federal tax authority.

Historical precedents underscore the seriousness with which the IRS pursues these regulations. The infamous gangster Al Capone's conviction on tax evasion charges in 1931, despite his myriad of other criminal activities, is a testament to the agency's commitment to enforcing tax laws. Capone's failure to report income from his illicit enterprises, despite a lavish public lifestyle, ultimately led to his imprisonment, illustrating the potential consequences of disregarding this requirement.

The case of Al Capone is not isolated. In 1927, the Supreme Court's decision in United States v. Sullivan established that income from illegal activities is not exempt from taxation under the Fifth Amendment, which protects against self-incrimination. This ruling has been instrumental in prosecuting individuals involved in illegal activities, as evidenced by the case against Aldrich Ames, a former CIA officer convicted of espionage and tax evasion for failing to declare income from his espionage activities for the Soviet Union.

While the notion of reporting illegal income might seem counterintuitive, it is grounded in the legal principle that all income, regardless of its source, is taxable. This policy serves not only as a means of ensuring tax compliance but also as a tool for law enforcement in tracking and prosecuting criminal activities. The requirement reflects the broader ethos of the U.S. tax system, emphasizing the universality of tax obligations and the principle that no income is beyond the reach of taxation.

As this unusual aspect of tax law gains traction online, it serves as a reminder of the extensive reach of tax obligations and the intricate ways in which tax policy intersects with law enforcement and criminal justice.
