U.S. Customs and Border Protection has renewed its warning on CBP cash declaration rules after officers at Fort Lauderdale–Hollywood International Airport arrested an outbound traveller and seized more than $53,800 in undeclared U.S. currency on 1 July.
The traveller, bound for Kingston, Jamaica, initially declared he was not carrying currency. A subsequent inspection uncovered the cash, and the individual was arrested through Homeland Security Investigations on money laundering charges under Title 18, U.S. Code, Section 1956, as well as a violation of 31 U.S. Code § 5316, which covers failure to report the international transportation of currency or monetary instruments.
What the CBP Cash Declaration Rules Actually Require
The federal mandate is straightforward: any traveller carrying currency or monetary instruments totalling more than $10,000, whether entering or leaving the United States, must file a declaration with the U.S. Department of the Treasury. The reporting threshold applies to outbound as well as inbound passengers, a point that catches travellers off guard. For families or groups travelling together, the $10,000 limit applies to the collective amount carried, not to each individual.
Travellers can satisfy the requirement by completing FinCEN Form 105 electronically before departure or arrival, or by downloading the form and presenting it directly to border officers. The declaration covers business travellers, those sending money abroad, and individuals bringing savings back home. Crucially, CBP stresses that the reporting obligation is not a tax and does not restrict how much currency a person may legally carry: it is a financial crime enforcement mechanism.
In the statement released on 16 July, Daniel Alonso, Director of Field Operations for CBP’s Miami and Tampa Field Office, said that ‘criminal organisations often rely on bulk cash smuggling to move illicit proceeds across international borders.’ Alonso added: ‘CBP officers remain vigilant in identifying these violations and work closely with our law enforcement partners to disrupt transnational criminal activity while protecting the integrity of our nation’s borders.’
Seizure Volumes and the Forfeiture Process
The Fort Lauderdale arrest is not an isolated case. In April, Homeland Security Investigations and CBP officers also seized more than $44,000 in unreported currency from a passenger at Philadelphia International Airport. CBP data on currency and monetary instrument seizures shows $48.5 million in total seizures as of June 2026, with the full fiscal year 2025 figure reaching $66.6 million, up from $53 million in fiscal year 2023 and $45 million in fiscal year 2024.
Seized funds remain in federal custody while investigations and the legal forfeiture process continue. Owners retain the right to contest the forfeiture and demonstrate a lawful source or intent for the funds. Where no valid petition is filed within the required window, the money is transferred to the Treasury Forfeiture Fund, administered by the Department of the Treasury, and directed towards state and local law enforcement operations, further training, and compensation for fraud victims.
CBP’s statement sets out the range of consequences clearly: ‘Failure to report currency or filing a false report may result in the seizure of the currency and could lead to civil or criminal penalties.’ In the most serious cases, where money laundering is established in federal court, criminal prosecution follows, as the Fort Lauderdale case demonstrates.
For travel agents and tour operators advising clients on international itineraries, the CBP cash declaration rules warrant routine inclusion in pre-departure briefings, particularly for group bookings where the collective threshold can be reached quickly and the per-person misconception remains common. CBP’s July statement signals the agency intends to maintain the current tempo of enforcement at major gateway airports.
