BSA, AML and suspicious activity reports

Compiled by the Sitonce editorial team from the NMLS Resource Center and the federal regulations named belowUpdated 2 min readFacts verified 4 September 2026
The short answer

A suspicious activity report must be filed within 30 calendar days of initial detection. A currency transaction report is required for cash over 10,000 dollars in a day. Disclosing a SAR to its subject is prohibited.

The Bank Secrecy Act framework reaches residential mortgage lenders and originators, and the exam treats it as a set of hard rules with hard numbers.

The two reports

Learn both numbers. They are among the most reliably asked figures in this part of the syllabus.

The confidentiality rule

You may not tell the subject of a suspicious activity report that one has been filed, or that one is being considered.

Not a hint, not a warning, not a suggestion they might want to withdraw the application. The prohibition is absolute.

This is the most tested point in the whole area

A scenario will describe an originator who suspects fraud and asks what they should do. Any option involving telling the borrower is wrong, however sympathetically it is phrased.

The program requirements

An institution must have an anti-money laundering program with four pillars: internal policies and controls, a designated compliance officer, ongoing training, and independent testing.

Four. The count is asked.

Structuring

Breaking a large cash transaction into smaller ones to avoid a reporting threshold is itself an offense, regardless of whether the underlying money is legitimate.

A borrower depositing 9,500 dollars on three consecutive days has structured, and that is reportable on its own.

The Red Flags Rule

Separate from anti-money laundering but often examined alongside it. It requires a written identity theft prevention program to detect and respond to indicators of identity theft.
