This page sets out the law behind a customs currency seizure: what the government is allowed to take, under which statutes, on what deadlines, and who has to prove what. If what you need is the practical path from a seizure to getting your money back, start with our guide to recovering seized cash, which walks through the process and the choices in front of you. This page is the reference underneath it.
What Counts as a Monetary Instrument
Everything starts here, and this is the part people get wrong most often, including people who tried to comply.
The reporting requirement at 31 U.S.C. § 5316 applies to “monetary instruments,” a term defined at 31 C.F.R. § 1010.100(dd). It is broader than cash and narrower than “money,” and the dividing line for negotiable instruments is not the amount or the type of document. It is whether title passes on delivery.
| Category | What it covers |
|---|---|
| Currency | Coin and paper money of the United States or of any other country that is designated as legal tender and circulates as an accepted medium of exchange in the country of issuance. 31 C.F.R. § 1010.100(m). |
| Travelers checks | In any form, signed or unsigned. |
| Negotiable instruments | Personal checks, business checks, official bank checks, cashier’s checks, third-party checks, promissory notes and money orders, but only where they are in bearer form, endorsed without restriction, made out to a fictitious payee, or otherwise in such form that title passes upon delivery. |
| Incomplete instruments | Instruments that are signed but with the payee’s name omitted. |
| Bearer securities | Securities or stock in bearer form, or otherwise in such form that title passes upon delivery. |
The test that decides most close cases
A $40,000 cashier’s check made payable to a named person and not endorsed is not a monetary instrument, because title does not pass on delivery. Whoever finds it in the street cannot cash it. The same check endorsed in blank on the back is one. And a check that is signed with the payee line left blank is one, because anyone can fill it in. The document looks identical in each case. The legal answer is completely different.
What Is Not a Monetary Instrument
- Money in a bank account. A wire transfer is not transportation of a monetary instrument. Nothing physical crosses the border.
- Credit cards and debit cards tied to an account.
- Checks made payable to a named payee and not endorsed, as above.
- Warehouse receipts and bills of lading. These are expressly excluded by the regulation.
- Gold, bullion and jewellery. Not currency and not a monetary instrument, so they do not count toward the $10,000 threshold. They are merchandise, they belong on your customs declaration, and undeclared they can be seized under 19 U.S.C. § 1497. Travellers who learn the first half of that rule and stop reading lose the goods.
- Counterfeit notes. They are not legal tender and do not circulate, so they fail the definition of currency. They are also contraband, forfeited under 18 U.S.C. § 492 and not recoverable.
Two categories sit in genuinely unsettled territory. Prepaid and stored-value cards are not listed in the regulation, a proposed rule to capture them was never finalised, and CBP has nonetheless treated them as reportable in some cases. Cryptocurrency carried on a device or as a seed phrase is likewise outside the regulation’s list as written. Neither is a question to answer from a website.
How the $10,000 Threshold Is Measured
Three rules decide whether you crossed it, and each one catches people who thought they were under.
- Everything aggregates. Currency plus travelers checks plus qualifying instruments, in any combination, counted together.
- Foreign currency converts. The threshold is $10,000 in U.S. dollars or the foreign equivalent. Euros, pesos and pounds are added at their dollar value, and a traveller carrying nothing but foreign notes can be well over the line without holding a single dollar.
- Groups are treated as one. CBP treats people travelling together as transporting a combined total. Four travellers with $4,000 each are carrying $16,000, and a report was required even though no individual exceeded the threshold.
There is no limit on the amount you may carry and no tax on carrying it. The requirement is to report. A traveller who files an accurate FinCEN Form 105 and carries $200,000 has done nothing wrong and keeps it. A traveller who carries $10,100 and says nothing can lose all of it, not just the excess.
The Three Statutes
Almost every customs currency seizure rests on one or more of these. Which one CBP has invoked appears in your paperwork, and it changes how the case should be handled.
| Statute | What it requires the government to show | Criminal maximum |
|---|---|---|
| Failure to report 31 U.S.C. § 5316 |
Knowing transport of more than $10,000 in monetary instruments into or out of the United States without filing a report, or with a materially false one. No intent to conceal is required. | 5 years, under § 5322 |
| Bulk cash smuggling 31 U.S.C. § 5332 |
Concealment of more than $10,000, transport across a U.S. border, and intent to evade the reporting requirement. The concealment and the intent are both elements. | 5 years |
| Structuring 31 U.S.C. § 5324 |
Breaking up or arranging amounts for the purpose of evading a reporting requirement. The money’s source is irrelevant; the offence is against the reporting system. | 5 years, or 10 where part of a pattern of illegal activity involving more than $100,000 in a 12-month period |
The forfeiture authority sits in 31 U.S.C. § 5317(c), which permits criminal forfeiture on conviction and civil forfeiture of property involved in a violation, and in § 5332(b) for bulk cash smuggling. Each of the three has its own page here: failure to report, bulk cash smuggling, and structuring.
Why a smuggling allegation changes everything
A bare failure to report is a paperwork violation, and the mitigation guidelines were written with honest travellers in mind. A § 5332 allegation imports concealment and intent, which is why cases involving money taped to a body, sewn into clothing or hidden in a vehicle resolve so differently from cases involving money sitting in a suitcase. If your notice cites § 5332, the first task is understanding what CBP says the concealment was.
The Deadlines
Customs currency forfeitures run under the Civil Asset Forfeiture Reform Act, which sets most of the clock. These are the dates that matter.
| Event | Deadline | Authority |
|---|---|---|
| Government sends the notice of seizure | No more than 60 days from the date of seizure | 18 U.S.C. § 983(a)(1)(A)(i) |
| You file a CAFRA claim to go to court | The date in the notice, which cannot be earlier than 35 days after it was mailed | 18 U.S.C. § 983(a)(2)(B) |
| You file an administrative petition instead | Generally 30 days from the date of the notice. The notice states the date. | 19 C.F.R. Part 171 |
| Government files a forfeiture complaint after your claim | 90 days from the claim, or it must return the property | 18 U.S.C. § 983(a)(3)(A) |
| Outer limit on commencing a forfeiture action | 5 years from discovery of the offence | 19 U.S.C. § 1621 |
Two practical notes. The 60-day notice period is a deadline on the government, not on you, and notices do arrive late or go to an old address; our page on responding to the custody receipt covers what to do in the gap. And the choice between a claim and a petition is made on the election of proceedings form, which is difficult to undo once returned.
Who Has to Prove What
This is the most consequential thing on this page and the thing most commonly stated backwards, including in places that ought to know better.
The burden depends entirely on which route you take, and the two routes are not variations on a theme. They are different proceedings with different rules.
| Route | Who carries the burden |
|---|---|
| Judicial, after a CAFRA claim | The government. It must prove by a preponderance of the evidence that the property is subject to forfeiture (18 U.S.C. § 983(c)(1)), and where its theory is that the money facilitated an offence, it must show a substantial connection between the money and that offence (§ 983(c)(3)). You are not required to prove your money was clean. |
| Administrative petition | Practically, you. A petition asks CBP to exercise discretion in your favour rather than adjudicating liability. There is no statutory burden of proof, but relief is conditioned on documenting a legitimate source and intended use, so the work falls on the petitioner. |
Nobody is presumed guilty here
You will read, in many places, that seized cash is presumed to be criminal proceeds until the owner proves otherwise. That has not been the law in a judicial forfeiture since CAFRA was enacted in 2000. The reason the proposition keeps circulating is that it describes the administrative process reasonably well, and most cases go that way. The difference matters enormously when the amount is large enough to justify going to court.
CAFRA also provides a statutory innocent owner defence at 18 U.S.C. § 983(d), for an owner who did not know of the conduct or who did all that could reasonably be expected to stop it. That defence belongs to the owner and must be proved by the owner, by a preponderance. It is the route for a person whose money was carried by someone else.
There Is a Constitutional Ceiling
Forfeiting the entire sum for a paperwork violation is not automatically permissible. In United States v. Bajakajian, 524 U.S. 321 (1998), the Supreme Court held that forfeiture of $357,144 for a failure to report violated the Excessive Fines Clause of the Eighth Amendment, because the forfeiture was grossly disproportional to the gravity of the offence. The money was lawfully earned and the only crime was the failure to file a form.
Bajakajian is not a general escape hatch and it is raised far more often than it succeeds. It is a serious argument where the funds are demonstrably legitimate, the violation is purely a reporting one, and the sum is large. Our page on the money seizure process covers where it fits in a case strategy.
What the Seizure Costs Beyond the Money
A currency seizure is recorded, and the record travels. Trusted traveller membership in Global Entry, NEXUS or SENTRI is commonly revoked. Secondary inspection becomes routine on later trips. For non-citizens, the record can surface in immigration proceedings and visa applications. These consequences follow from the seizure itself and are not erased by recovering the money, which is one reason how a case is resolved matters as much as whether it is. Our page on the long-term consequences of a cash seizure covers this.

Frequently Asked Questions
Is a cashier’s check a monetary instrument?
Only if title passes on delivery. A cashier’s check made payable to a named payee and not endorsed is not a monetary instrument and does not count toward the $10,000 threshold. The same check endorsed in blank is one, and so is a check signed with the payee line left blank. The form of the instrument decides it, not the amount.
Does gold count toward the $10,000?
No. Gold bullion and jewellery are not currency and not monetary instruments, so they do not count toward the currency reporting threshold. They are merchandise and must be declared on your customs declaration, and undeclared they can be seized under 19 U.S.C. § 1497 with a penalty on top.
Is the $10,000 limit per person?
Not for people travelling together. CBP treats a family or group as transporting a combined total, so four travellers with $4,000 each are treated as carrying $16,000 and a report was required. Dividing money among travellers to keep each one under the threshold is structuring under 31 U.S.C. § 5324, which is a separate violation.
Does CBP have to prove my money came from something illegal?
In a judicial forfeiture following a CAFRA claim, yes. The government bears the burden of proving by a preponderance of the evidence that the property is forfeitable, and where it says the money facilitated an offence it must show a substantial connection. In the administrative petition process there is no such burden on the government, because you are asking for discretionary relief rather than contesting liability, and documenting legitimate source and intended use is a condition of that relief.
How long does CBP have to send me a notice of seizure?
No more than 60 days from the date of seizure, under 18 U.S.C. § 983(a)(1)(A)(i), with a longer period where state or local authorities seized the property and turned it over. Notices do go astray, and the deadline running against the government does not protect you if you never see the letter.
Can I lose the whole amount over a form?
The entire sum is exposed to forfeiture, not just the amount above $10,000. There is a constitutional ceiling: United States v. Bajakajian held that forfeiting $357,144 for a pure reporting violation was grossly disproportional and violated the Excessive Fines Clause. That argument is raised more often than it succeeds and depends heavily on the legitimacy of the funds and the nature of the violation.
What if the money was not mine?
The reporting obligation attaches to the person physically transporting the instruments, regardless of who owns them, so carrying money for someone else does not change whether a report was required. Ownership matters at a different stage. CAFRA provides an innocent owner defence at 18 U.S.C. § 983(d) for an owner who did not know of the conduct, and that defence must be proved by the owner.
Does a bank wire need to be reported?
Not under this requirement. Section 5316 applies to physically transporting monetary instruments across a border. A wire transfer moves nothing physical and is governed by separate reporting rules that fall on the financial institution rather than on you.
