The report covers IRS cash seizures against businesses and individuals suspected of deliberately trying to avoid federal reporting requirements for large bank deposits.
To combat criminal activity, individuals and businesses are required to report all bank deposits greater than $10,000 to federal authorities. Intentionally splitting up large sums of cash into sub-$10,000 amounts to avoid that reporting requirement is known as “structuring” and is illegal under the federal Bank Secrecy Act.
But many business owners engaged in perfectly legal activities may be unaware of the law. Others are covered by insurance policies that don't cover cash losses greater than $10,000. Still others simply want to avoid extra paperwork, and keep their deposits less than $10,000 on the advice of bank employees or colleagues.
While structuring is technically a crime, it's something of a secondary one. The reporting requirements were enacted to detect serious criminal activity, such as drug dealing and terrorism. They “were not put in place just so that the Government could enforce the reporting requirements,” as the IG's report puts it.
But according to the report, that's exactly what happened at the IRS in recent years. The IRS pursued hundreds of cases from 2012 to 2015 on suspicion of structuring, but with no indications of connections to any criminal activity. Simply depositing cash in sums of less than $10,000 was all that it took to arouse agents' suspicions, leading to the eventual seizure and forfeiture of millions of dollars in cash from people not otherwise suspected of criminal activity.
