IRS structuring is the federal crime of intentionally breaking up cash transactions into smaller amounts to avoid triggering mandatory reporting requirements, such as the
Currency Transaction Report (CTR) or
IRS Form 8300. Under
31 U.S.C. § 5324, it is illegal to structure, attempt to structure, or assist others in structuring transactions to evade these records, regardless of whether the underlying funds are from legitimate sources.
The primary reporting thresholds that trigger structuring violations are:
- Bank CTRs: Financial institutions must report cash deposits, withdrawals, or exchanges exceeding $10,000 in a single business day.
- Form 8300: Businesses must report cash payments exceeding $10,000 received in the course of their trade or business.
Common examples of structuring include depositing
$9,900 instead of
$10,000, making multiple smaller deposits across different days to stay under the limit, or splitting a single large payment into several smaller checks to avoid paperwork.
Consequences and Detection The IRS and
FinCEN use advanced data analytics to detect patterns of suspicious activity, such as frequent sub-$10,000 deposits or withdrawals. Penalties for structuring are severe and include:
- Civil Penalties: Fines equal to the amount involved and forfeiture of the structured funds.
- Criminal Penalties: Fines up to $500,000 and imprisonment for up to 10 years.
Intent is the critical factor; prosecutors do not need to prove that the funds were illicit (e.g., from drug trafficking or tax evasion), only that the individual
willfully split transactions to avoid reporting. Even small business owners who structure deposits to "avoid hassle" can face criminal charges and asset seizure.
