Answer by Brian Crow: It is commonly held that all joint owners benefit from a deposit to a joint account as any owner would have access to the funds. However, withdrawals are another matter. FinCEN has not published any guidance on the subject of withdrawals. A CTR is triggered by the same individual conducting transactions exceeding or benefiting from transactions exceeding $10,000.00. In this scenario, neither individual conducted more than $10,000.00 so you are left to decide if one or both members benefited from each of the withdrawals. If you conclude that they did, then file a CTR. If you determine that they did not, do not file.
Answer by John Burnett: I will only add to Brian's analysis to suggest that I'd find it hard to assume that Member B's $25 withdrawal is significant enough to have been made on behalf of both Member A and Member B.
