Quick answer: In most countries there is no limit on how much cash you can carry on an international flight, but above a set amount you must declare it to customs. The amount is US$10,000 in the United States, €10,000 entering or leaving the EU, £10,000 in the UK, C$10,000 in Canada and A$10,000 in Australia. It is lower in some places: US$5,000 in China and for foreign cash arriving in India, AED 60,000 (about US$16,300) in the UAE and SAR 40,000 (about US$10,700) in Saudi Arabia since mid-2026. Declaring is free and doesn't mean you pay tax. If you don't declare, customs can seize all the cash, not just the amount over the limit.
The rule applies on both ends of your trip: the country you leave and the country you arrive in can each have their own amount and their own form. Enter your route below to see both.
Add up everything for the whole family or group travelling together: banknotes in every currency, travellers' cheques and money orders. Most countries count them together.

The Rules That Apply Almost Everywhere
- It is a reporting limit, not a cap. In the US, UK, EU, Canada, Australia, Singapore and most other countries you can carry any amount once you declare it. A few countries do cap their own currency: China allows no more than ¥20,000 in yuan, the Philippines ₱50,000 in pesos, India ₹25,000 in rupees and Pakistan Rs 10,000 when leaving.
- All currencies count together. Customs add up dollars, euros, local money and anything else you carry at their exchange rate on the day. US$6,000 plus €5,000 is over a US$10,000 limit.
- More than banknotes counts. Travellers' cheques, money orders, bank drafts and cheques made out to "bearer" are included almost everywhere. In Saudi Arabia, Qatar and the UAE, gold, precious stones and jewellery count too.
- Families count together. The US customs form is one per family, the UAE adds cash carried by children to the parent's total, and splitting money between travellers to stay under the limit is a crime in the US (called structuring) and treated as evasion elsewhere.
- Declaring costs nothing. You don't pay duty or tax on cash you declare. Customs may ask where it came from and what it is for, so carry a bank withdrawal slip, sale contract or similar if the amount is large.

What Happens If You Don't Declare
Carrying the cash is legal; not declaring it is the offence. The usual result is that customs seize the money on the spot, and you then have to prove where it came from to get it back, which can take months and a lawyer.
- United States: all of the cash can be confiscated, and serious cases carry fines of up to $500,000 and up to 10 years in prison.
- Mexico: a fine of 20% to 40% of the amount over the limit, and prosecution if more than US$30,000 is undeclared.
- Hong Kong: up to HK$500,000 and two years in prison.
- Malaysia: up to RM1 million, a year in prison, or both.
- Singapore: undeclared cash is an offence under the anti-money-laundering law; travellers caught in 2026 received warnings or composition fines.
Customs dogs and scanners are trained to find banknotes, and airport staff regularly report large seizures, so "nobody checks" is not a plan.
Common Situations
Flights within the EU or within one country
Between EU countries there is no EU cash form, but Germany and several others can make you disclose €10,000 or more and explain where it came from. On domestic flights there is no declaration, though airport security can alert the police if they find a very large sum.
Changing planes
Transit rules differ. If you change planes without passing through immigration, most countries don't treat you as entering. If you leave the airport or collect your bags, you are arriving and must follow that country's rule. Check the transit country's customs website if you carry a large amount.
Moving abroad or carrying money for a house or wedding
A bank transfer is usually cheaper and safer than cash, and leaves the paper trail customs would ask for anyway. If you do carry it, declare it on both ends and keep proof of where it came from.
Gold and jewellery
Gold and jewellery are part of the cash limit in Saudi Arabia, Qatar and the UAE, and gold bars are declared separately in Japan and many other countries. Personal jewellery may also be checked under the duty-free rules for goods, which are a separate limit.
Cards, digital wallets and crypto
Debit and credit cards, money on your phone and cryptocurrency are not cash and are not declared at the border. A crypto hardware wallet is generally treated as a device, though rules are changing.
Frequently Asked Questions
How much cash can I carry on an international flight without declaring it?
Up to the declaration amount of each country on your route: just under US$10,000 or its equivalent for the US, EU, UK, Canada and Australia. Use the lower of the two countries' limits if you're unsure.
Is it illegal to fly with more than $10,000 in cash?
No. It is legal in the US and most countries as long as you declare it. Not declaring is what breaks the law.
Do I have to pay tax on cash I declare?
No. A cash declaration is a report, not a tax. Income tax on the money is a separate question for your home country.
Does the limit apply per person or per family?
In the US and the UAE, money carried by a family travelling together is added up, and in other countries splitting money to avoid declaring is treated as evasion. Declare if your group's total is over the limit.
How much Indian currency can I carry abroad?
Up to ₹25,000 per person in Indian rupees. Foreign currency you buy for the trip is separate; on your return, declare foreign cash over US$5,000 on the Currency Declaration Form.
