Do I need to declare cash when crossing a border?

What declaring cash actually means

A cash declaration is a report, not a payment. You tell customs how much you are carrying, where it came from and what it is for. No money is taken and no tax is charged on it.

It exists because governments track large movements of untraceable money as part of anti-money-laundering rules. Answering honestly on the form is usually the end of the matter.

trip1 bookings are paid online in cryptocurrency before you travel, so you do not need to carry cash for your hotel. You might still be carrying money for other reasons, and that is when these rules apply.

The thresholds you are most likely to meet

• United States: 10,000 US dollars or the foreign equivalent, entering or leaving. It is reported on FinCEN Form 105 and the threshold covers a family or group travelling together.
• European Union: 10,000 euros or the equivalent, entering or leaving the EU. There are no EU-wide rules for cash carried between EU countries, but individual member states can set their own.
• Great Britain: 10,000 pounds, entering or leaving. Northern Ireland uses a 10,000 euro threshold for travel to and from countries outside the EU.
• Elsewhere: Canada, Australia and many other countries also use 10,000 in their own currency, so 10,000 is a reasonable rule of thumb. Confirm with the destination's customs authority before you travel.

Cash means more than banknotes

The definition is wider than most people expect. Notes and coins count, and so do travellers cheques, unsigned cheques, money orders, promissory notes and bearer bonds.

The EU also counts gold coins with at least 90 percent gold content and gold bullion of at least 99.5 percent purity. Northern Ireland's rules include prepaid cards.

If you are anywhere near the threshold, add everything together rather than counting banknotes alone. Currency you are carrying in more than one denomination still counts as one total.

Family and group totals

In the United States and the United Kingdom the threshold is a combined one. If you are travelling as a family or group and the total reaches 10,000, you declare it, even though each person is carrying less.

Splitting money between travellers specifically to stay under the limit is called structuring, and it is an offence in its own right. Officers see it often and recognise the pattern.

What happens if you do not declare

Officers can also question or seize money below the threshold if they suspect it is linked to crime. Carrying evidence of where the money came from, such as a bank withdrawal receipt or a sale contract, makes that conversation much shorter.

How to declare

Most countries let you declare online before you travel or on a form at the border. The United States uses FinCEN Form 105, which can be filed electronically or on paper. The EU has a common cash declaration form used across member states.

Great Britain lets you declare online in advance or at the border. In some countries the cash question appears on the general customs form instead, which is explained in our guide to what a customs declaration form is.

Fill it in before you reach the desk if you can. Arriving with the form already completed is faster and looks far better than doing it under an officer's gaze.
