Introduction / Who is this for

This guide is for you if you are traveling with children across the U.S. border with more cash and are wondering if each child has a separate $10,000 limit. This is one of the most common myths in the Polish community, costing families tens of thousands of dollars annually in confiscations.

SHORT ANSWER — NO

Children do not have a separate $10,000 limit when crossing the U.S. border. The threshold counts collectively for the entire family traveling together.

In other words:

• A family of 4 (parents + 2 children) with $30,000 total — must declare.
• They cannot each have $9,999 and avoid the requirement.
• Attempting to split the amount among children is structuring — a federal crime with a penalty of up to 5 years in prison.
• Even an infant "with $9,999 in the car seat" does not create a separate limit. Money "transported on behalf of" a child is always attributed to the parent.

Why families think differently — where this myth comes from

The myth of "$10,000 per person" arises from a misunderstanding of the term "each person" in the regulations. Reading the text 31 CFR 1010.340(a) superficially: "Each person who physically transports … currency or other monetary instruments in an aggregate amount exceeding $10,000 at one time…" — it is easy to think: "each person has their own limit." But this is a misunderstanding.

The key is the definition of "at one time", which includes transporting "either alone, in conjunction with or on behalf of others" — alone, together with others, OR on behalf of others. So: if two parents go through customs, each has $6,000, but these are family funds — they are not two separate limits of $6k, it is one amount of $12,000 subject to declaration.

The second source of the myth: CBP Form 6059B (customs declaration) has a question starting with “Are you (or any family member traveling with you)…” — meaning the form directly asks about the entire family.

What CBP says exactly

The official interpretation from CBP (source: cbp.gov and help.cbp.gov):

"When families or groups are involved, the $10,000 threshold applies to the total amount they are carrying or sending collectively, not per individual."
(“When families or groups travel, the $10,000 threshold applies to the total amount carried collectively — not the sum per person.”)

And further:

"Families residing in one household and submitting a joint declaration must declare the aggregate value of their currency or monetary instruments when it meets or exceeds the $10,000 limit on their Customs Declaration Form (CBP Form 6059B)."
(“Families living at the same address and submitting a joint declaration must declare the total value of cash when it meets or exceeds the $10,000 threshold on CBP Form 6059B.”)

And still:

"A family only needs to submit one FinCEN Form 105 if they are traveling together. However, if any one member of the family brings in more than $10,000, they must also file a separate FinCEN Form 105."
(“A family traveling together submits one FinCEN Form 105. But if any family member brings in more than $10,000, that member must also file a separate FinCEN 105.”)

How it looks in practice — specific examples

Example 1. A family of 4: father, mother, two children (10 and 14 years old). They are flying to Poland for 3 weeks. They have $14,000 total (part in the father's briefcase, part in the mother's backpack, small change for the children for ice cream). Must declare. They fill out a joint CBP Form 6059B (marking YES) plus one FinCEN Form 105 for $14,000.

Example 2. A couple + an infant. Total amount $9,800. No need to declare — total under the threshold. The infant does not have a separate account limit.

Example 3. A family of 4, $22,000. The parents thought, "let's split it among the children at $5,500 each — we will each have less than $10,000." THIS IS STRUCTURING — a crime with a penalty of up to 5 years. Confiscation of the entire amount and possible criminal charges.

Example 4. An uncle with two nephews (16, 18 years old) flying together to Chicago from Warsaw. Each has their own money: uncle $11,000, one nephew $3,000, the other $4,000. The uncle must file a FinCEN 105 (over the threshold alone). The nephews with $3,000 and $4,000 — individually under the threshold, if that money is their own and unrelated. If it is a shared "family fund" — aggregation, totaling $18,000, all must declare.

Example 5. A father alone with his daughter (8 years old) entering the U.S. with $9,500. Under the threshold for the entire group — no need to declare. But if the daughter were 16 years old and had her own card with $1,500 savings for vacation — totaling $11,000, must declare.

Why splitting money among children is a crime

Among the Polish community, there is a “life hack”: since each theoretically has their own $10,000, let’s give each child $9,000 to their backpack and that’s it. This is exactly the scenario that the law calls currency structuring.

31 USC 5324(c) explicitly prohibits: "No person shall, for the purpose of evading the reporting requirements of section 5316— … structure or assist in structuring, or attempt to structure or assist in structuring, any importation or exportation of monetary instruments."

Penalties (31 USC 5324(d)):

• Fine up to $250,000
• Up to 5 years in prison (up to 10 years in the aggravated variant)
• Confiscation of the entire amount (not just the excess)
• All of this regardless of whether the money comes from a legal source

CBP in press releases is blunt: "When passengers split up the currency amongst themselves to avoid reporting it, that is currency structuring."

This means: it’s not that you will lose the “excess.” You will lose all the money. Plus potentially end up with criminal charges.

What happens when CBP detects split money

These are not theoretical scenarios — CBP regularly publishes reports of confiscations. A common pattern from documented cases:

• The family declares (e.g., verbally) $5,000 or $9,000 at customs
• CBP officers conduct a "secondary inspection" — detailed search of all persons and luggage
• They find money spread out in envelopes, in children's backpacks, in pockets, sometimes in infant car seats
• The entire amount is confiscated, regardless of the source
• The family receives a written notice of confiscation and the recovery procedure (which usually requires a lawyer, costs $5,000–15,000, and takes 6–18 months with no guarantee of success)

Examples documented by CBP (Dulles Airport, Washington): a family flying to Nigeria (confiscation of $68,000), a family flying to Ethiopia ($27,560), a couple flying to Egypt ($26,043), a couple flying to Lagos ($101,825). All these cases involved splitting money among family members.

How to do it RIGHT — when the family has over $10,000

Situation: you are flying with your family to/from the U.S., and you collectively have more than $10,000. Full procedure:

1. Count everything: U.S. cash, Polish cash (convert to USD on the day of travel), traveler's checks, money orders to bearer, bearer bonds. Sum up ALL family members.
2. Fill out FinCEN Form 105 — preferably online before the trip at fincen105.cbp.dhs.gov. Enter the total amount. Print the confirmation.
3. Fill out CBP Form 6059B on the plane (distributed by the crew). One declaration for the family with one address. Mark YES to the question about money over $10,000.
4. Prepare source documentation in paper form: sales notarization, donation agreement, bank statements, tax returns, employment verification.
5. At the CBP window: be the first person to declare. “I have a currency declaration. Here is my FinCEN 105 form.”
6. Answer questions specifically: where the money is from, where it is going, for what purpose. You have the right to an interpreter.
7. Do not sign forms you do not understand. Especially avoid “Disclaimer of Interest” — this waives your right to the money in case of confiscation.
8. Keep everything: FinCEN 105 with CMIR number, Form 6059B, all correspondence. For at least 5 years.

Common mistakes

• "Each child has their own $10,000 limit" — NO. The limit is for the entire group/family.
• Splitting money among children to avoid the threshold — a crime (structuring), up to 5 years in prison.
• Packing money in a child's backpack to make it "not look like it" — that is concealment + structuring at the same time.
• Counting only USD — foreign currency (PLN, EUR) also counts towards the threshold.
• Ignoring traveler's checks and money orders to bearer — everything counts.
• Lying to CBP about the amount — false statement (18 USC 1001), an additional 5 years.
• Only verbal declaration — written FinCEN 105 is required, it is not enough to just tell the officer.
• Lack of source documentation — just having the money can lead to seizure even after declaration if the officer deems the source suspicious.

What’s next

1. Explain to the whole family (especially older children 14+) — everyone must know that this is a collective limit and never say "we are splitting it among ourselves".
2. If you plan to transport money as a family over $10,000 — fill out FinCEN 105 in advance online.
3. Gather source documentation at least a week before travel.
4. Consider alternatives: international bank transfer (SWIFT, Wise, Revolut) is cheaper, safer, and does not require border declarations (banks have their own reporting, but you as a client do nothing additionally).
5. Consult with an attorney if the amount is over $50,000 or the source is complicated (business sale, international inheritance, transfer of funds from a Polish account).
6. If confiscation has already occurred — immediately contact an attorney specializing in asset forfeiture. The deadline for filing a claim is strict — usually 30 days from notification. After the deadline, the money is lost.
