Do You Have to Declare Cash in Your Bag?

Yes, if you carry more than $10,000 in total across the US border, in any bag or on your person.

Typical situation

You are travelling to or from the US with a large amount of cash in your bag, for a purchase or a family reason, and want to know what you must report.

Main answer · berabags Editorial Team · Rules view

Yes. If you carry, mail or ship more than $10,000 in total in currency or monetary instruments into or out of the US, you must report it to US Customs and Border Protection (CBP). There is no limit on how much you may carry, only a duty to report.

What the rule covers

It covers cash and monetary instruments such as travellers’ cheques, in any currency, in your bag, in your clothing or in a vehicle.
The $10,000 threshold is an aggregate. Amounts carried by family members travelling together are counted together, according to CBP.
You report it on FinCEN Form 105, and CBP’s page explains how to complete it online or on paper. Arriving travellers also declare the amount on the customs declaration form.

What to do

Count the money, including all currencies and instruments, before you travel.
If the total is over $10,000, fill in the report before or when you reach the border.
Tell the officer when asked, and show the money.
Keep a copy of the report and any proof of where the money came from, such as a receipt or bank record.

What happens if you do not report

CBP says that failing to report can lead to seizure of the money, fines and even criminal penalties. Honest mistakes are better corrected by telling the officer than by waiting to be asked.

Where this answer stops

This is general information based on CBP and USAGov pages. Other countries have their own limits and forms, and the amounts and forms can change. This is not legal advice.

Keep cash in a pouch or envelope that is easy to take out and show, not spread around several bags. A clear, organised bag makes the declaration quicker and less stressful for you and the officer.

Large amounts of cash are a theft risk. Keep them on you or in a bag that never leaves your sight, with a zipped inner pocket, and avoid checking them in the hold. Do not label the bag in a way that advertises what it holds.

You can bring in any amount of money, but you must report amounts above the threshold. Not reporting can lead to seizure of the money and penalties, which cost far more than the time it takes to fill in the form.
