How much cash can you fly with undeclared?

Most localities in the United States have a $10,000 per person restriction. However, if numerous people are travelling together, they are not allowed to have more than this amount without disclosing the cash or things that total more than this amount to customs.



When flying internationally in 2026, the general rule is that you can carry up to the equivalent of $10,000 USD (or €10,000 in the EU) without having to declare it to customs. This limit applies to the total value of all "monetary instruments" you are carrying, which includes physical banknotes, coins, traveler's checks, and endorsed money orders. It is important to note that this is a per-household or per-family limit if traveling together; you cannot circumvent the rule by splitting $20,000 between two family members. If you are carrying more than $10,000, you must fill out a Currency Declaration Form (CDF) at the airport. Contrary to popular belief, it is not illegal to carry more than this amount; it is only illegal to not declare it. In 2026, failing to declare large sums can lead to the immediate seizure of the cash, heavy fines, and potential criminal charges. Specific countries may have lower limits (for example, India requires declaration for amounts over $5,000 in cash notes), so always check your destination's specific customs portal.
