US Customs Regulations for Flying with Cash
When you enter or leave the US, you must declare cash or monetary instruments worth more than $10,000. This is part of America’s effort to prevent money laundering, terrorist financing, and other illegal activities.
The rule applies to:
- US dollars and foreign currency equivalents
- Traveler’s checks
- Money orders, cashier’s checks, and promissory notes
- Bearer bonds and negotiable instruments
- Precious metals and rare coins (considered cash for customs)
Important: The $10,000 limit applies to the total carried by a group, not per person. For example, a family of four each carrying $3,000 (total $12,000) must declare the amount.
Cash Limits in Other Countries
Different countries have their own cash declaration rules:
- United Kingdom: Declare £10,000 or more when entering/leaving.
- European Union: Declare €10,000 or more.
- Canada: Declare amounts over CAD 10,000.
- Australia: Declare more than AUD 10,000 using a CBM-PC form.
Flying with Cash Domestically
If you are flying within the United States:
- There is no legal limit on how much cash you can carry.
- The TSA doesn’t set a cash limit, but large amounts may trigger extra screening.
- Law enforcement may question you about the source of funds.
- In rare cases, cash can be seized under civil asset forfeiture if suspected of illegal activity.
Flying with Cash Internationally
When traveling internationally, declare more than $10,000 using FinCEN Form 105.
Failure to declare can lead to:
- Seizure of funds
- Civil fines
- Criminal prosecution
- Loss of Global Entry status
What Counts as Cash for Customs
US CBP considers the following as currency:
- Coins and banknotes (US or foreign)
- Traveler’s checks
- Signed money orders without a named payee
- Bearer bonds, securities, and stocks in bearer form
- Bullion and high-purity gold coins
Not considered cash:

Penalties for Not Declaring Cash
Failing to declare over $10,000 can result in:
