CBP has made it possible to file a FinCEN 105 form online at fincen105.cbp.dhs.gov — and at first glance, this seems like exactly the kind of streamlined solution travelers have been waiting for. File your report before you leave the house, show up at the airport with your paperwork already done, and walk through without a hassle. Simple, right?
Not quite. If you file the FinCEN 105 online, you still have to physically report to a CBP officer at the port of entry or departure to confirm the filing. The online form does not substitute for the in-person declaration — it supplements it. Travelers who file online and then walk through the checkpoint without stopping to find a CBP officer and confirm their declaration are still in violation of 31 U.S.C. § 5316, just as if they had never filed anything at all.
I made a video specifically about this because it is genuinely counterintuitive and the consequences of getting it wrong are severe:
Why the Online Filing Alone Is Not Enough
The FinCEN 105 reporting requirement under 31 U.S.C. § 5316 has two components that both need to be satisfied. First, you must file the report. Second, you must make the declaration to a CBP officer at the time of crossing. These are not the same thing, and completing one does not complete the other.
The online filing system records your declaration in advance — it is essentially a pre-filing that creates a record of your intent to report. But CBP needs to confirm, at the actual moment of crossing, that the amount you filed matches what you are actually carrying, that the monetary instruments are what you described, and that all the information is accurate. That confirmation happens in person, with a CBP officer, at the port. Without it, the online filing is an incomplete declaration.
This is not a technicality that CBP overlooks. Travelers who file online and proceed through the checkpoint without confirming with an officer can and do have their currency seized for failure to properly complete the reporting process. The online system was designed to make the process more convenient — it was not designed to eliminate the requirement to interact with CBP at the border.
What You Actually Need to Do
If you are traveling internationally with more than $10,000 in currency or monetary instruments — in either direction, entering or leaving the United States — here is the correct process:
- File the FinCEN 105 online before your trip if you want to get the paperwork done in advance. The online system is available at fincen105.cbp.dhs.gov.
- At the port of entry or departure, find a CBP officer and confirm your declaration. Do not wait to be asked. Proactively approach an officer, tell them you have currency to declare, and present your filing. This is the step that legally completes the reporting requirement.
- Have your documentation ready. CBP may ask about the source of the funds and their intended use. Bank statements, business records, purchase agreements, or other supporting documentation that explains why you are carrying the money can help demonstrate the legitimacy of the funds if questions arise.
The requirement applies to U.S. currency, foreign currency, traveler’s checks, money orders, negotiable instruments in bearer form, and certain prepaid access devices. It applies to individuals and to groups traveling together — if you are part of a family or traveling group, the combined amount all members are carrying is what matters, not each person’s individual share. Splitting currency among traveling companions to keep each person’s amount under $10,000 is structuring — a separate federal violation that makes the situation significantly worse.
If You Made This Mistake and CBP Seized Your Money
Filing online and then failing to confirm with a CBP officer is a common misunderstanding, and it is the kind of good-faith error that can and should be documented carefully in a petition for return of the funds. The fact that you proactively filed — even if the in-person confirmation step was missed — is a meaningful mitigating factor in the petition process. It distinguishes your case from one involving deliberate concealment or a complete failure to report, and CBP’s FP&F office does take good faith into account in evaluating mitigation.
That said, good intentions do not automatically result in return of the funds. You still need to go through the election of proceedings process, file within the applicable deadlines, and make a documented case for why your money should be returned.
