How much money to bring on a trip without declaring in 2026

Reading: 10 min · Travel · Picnic

There is a question that comes up every time before an international trip: "how much money can I bring without getting caught in the customs net?". The answer surprises almost everyone: there is no ceiling. You can travel with $5,000, $50,000, or $500,000. What exists is an obligation to declare when the cash amount exceeds $10,000, both when leaving Brazil and entering the United States. Declaring is free, fast, and legal. The problem is never the amount, it's carrying too much cash and not declaring it.

This guide puts the two rules that matter most to Brazilian travelers side by side—the Brazilian Federal Revenue (Receita Federal) and US customs—explains what counts as "cash", and shows why the safest and cheapest way to carry money in 2026 almost never involves carrying a wad of bills.

How much money can I bring on a trip?

The direct answer: as much as you want. On the routes covered by this guide—leaving Brazil and entering the United States—there is no legal ceiling on the amount you can transport. What exists is a declaration threshold. Above it, you must inform the authorities how much you are carrying. Below it, you don't need to do anything.

This threshold is $10,000 (or the equivalent in another currency) in most destinations relevant to Brazilians, including leaving Brazil and entering the United States. It is a reporting number, not a tax and not a ceiling. Declaring money does not generate any charges: it is just a record for money laundering control purposes.

The most common confusion is thinking that declaring means paying something or that exceeding $10,000 is prohibited. Neither is true. What leads to seizure and fines is not declaring when you should (and, in the United States, splitting the money among the group to purposely stay below the limit, as I explain below).

Brazil: the Federal Revenue rule

When leaving Brazil (or entering back) with cash amounts exceeding $10,000, or the equivalent in another currency, you are required to fill out the Electronic Traveler's Declaration of Goods (e-DBV - Declaração Eletrônica de Bens de Viajante). The rule applies in both directions and to any physical currency, adding up everything you carry.

The process is online and simple:

• Fill out the e-DBV on the Federal Revenue portal, at edbv.receita.fazenda.gov.br, before boarding.
• Present yourself to the Federal Revenue at the airport or border crossing, if requested.
• For amounts over $10,000, the authority may ask for proof of the origin of the funds, so it is worth bringing a bank statement or document showing where the money came from.

The legal basis is in the Normative Instructions of the Federal Revenue (IN RFB No. 1,059/2010 and No. 1,385/2013), and the official step-by-step guide is in the Federal Revenue Traveler's Guide. If you travel with less than the equivalent of $10,000 in cash, you do not need to declare anything.

Do not confuse it with the baggage allowance

Many people mix up the money limit with the shopping allowance, and they are different things. The baggage exemption allowance for those returning to Brazil by plane is about $1,000 in goods (products purchased abroad). If you exceed this, there is a tax on the excess. This rule is about merchandise, not the money you carry. You can return with $9,000 in cash without declaring and still have to declare a $1,500 laptop bought abroad. They are two separate controls.

United States: the FinCEN Form 105

The United States is the most common destination for the Picnic traveler, so it is worth knowing their rule carefully. When entering or leaving the US with more than $10,000 in currency or monetary instruments, you must report it on the FinCEN Form 105, also called the CMIR (Report of International Transportation of Currency or Monetary Instruments). Enforcement is carried out by US Customs and Border Protection (CBP), based on the Bank Secrecy Act.

Three details that catch unsuspecting Brazilians:

• The limit is combined per family or group traveling together. If you travel with your spouse and each carries $6,000, the total is $12,000 and the group must declare. Dividing the money among people to "stay below" is exactly what the law calls structuring, and it is an offense.
• Declaring costs nothing and does not limit the amount. You can legally enter with $40,000, as long as you fill out the form. No one will tax this money upon entry.
• The penalties for not declaring are heavy. Undeclared money can be seized and entirely forfeited (seizure and forfeiture). The civil penalty can reach the total amount transported and, in criminal cases, there is a fine of up to $500,000 and/or up to ten years in prison. You can consult the official rule at USA.gov.

The practical takeaway is simple: if for any reason you really need to cross the border with more than $10,000 in cash, declare it. The form is free and solves the issue. The expensive mistake is thinking that "no one will see".

What counts as "cash"?

Here is the point that changes everything when planning. And the two rules do not cover exactly the same things:

• In Brazil (e-DBV): you declare physical paper money, that is, bills and coins (reais, dollars, euros). The Federal Revenue does not include credit instruments, checks, or traveler's checks here.
• In the US (FinCEN 105): in addition to paper money, bearer monetary instruments are also included, such as traveler's checks, money orders, and bearer checks, which count towards the $10,000 limit.
• What does not count in either: the balance you have on a card linked to an account. A Visa card with a dollar balance is not "cash" crossing the border; it is a means of accessing an account. It does not enter the declaration sum and does not need to be reported on the e-DBV or the FinCEN 105.

In other words, the declaration bureaucracy exists for paper money. Those who carry their money on a card simply bypass it. This is the first reason why carrying cash no longer makes sense as a primary strategy.

So how much should you actually bring?

Knowing that there is no ceiling and that a card bypasses the declaration, the right question is no longer "how much can I bring" but rather "how much is worth carrying in cash". And the answer, for most trips, is: little.

Carrying a lot of cash has three costs that do not appear in the declaration limit:

1. Physical risk. Lost or stolen money has no chargeback, no blocking, no replacement. You assume 100% of the loss.
2. High entry cost. Buying paper dollars at an exchange bureau embeds the 3.5% IOF (Financial Operations Tax) plus the tourist dollar spread, which usually sits between 4% and 8% above the reference exchange rate. You pay dearly before spending your first dollar.
3. Idle money. What is left over from the trip becomes bills in a drawer, and reselling it for reais embeds another spread. You lose on both ends.

Therefore, the practical recommendation is to bring a small cash reserve, calculated only for tips, informal transport, and emergencies—something like $100 to $300 on a typical trip—and concentrate the rest of the budget on a card. This keeps you well away from the declaration limit and also reduces the total cost. The complete logic of this division is in the guide on the best way to bring dollars for a trip.

Need physical money during the trip? You can withdraw it, but pay attention. Withdrawing abroad has a fixed cost per operation and does not always pay off. It is worth reading beforehand when withdrawing from an ATM makes sense so you don't pay unnecessary fees.

Why the card bypasses the entire bureaucracy

Combine the three problems of cash—declaration, risk, and cost—and the card solves all three at once.

The Picnic card works with a digital dollar balance inside an international account. Picnic, a technology platform, does not charge IOF on this card category and does not charge an issuer spread. An honest caveat is worth noting: currently, there is no IOF levied on this type of transaction, and a future charge would depend on complementary regulation not yet published. What is left today depends only on the currency you spend in:

• Spending in dollars (purchases and subscriptions priced in USD), there is no conversion: the spread is 0% and the IOF is 0%, meaning the total cost is zero.
• Spending in another currency, such as euros, yen, or pounds, only the Visa network margin applies, which is about 0.3%, the same that every Visa card in the world applies.

Compare this with cash, which starts at 3.5% IOF plus a 4% to 8% spread just to put the dollars in your hand. And remember that the card balance does not fall under the declaration rule: you cross any border without filling out an e-DBV or FinCEN 105 because of it, as it is not physical money.

There are also operational advantages. The card works with Apple Pay and Google Pay, you can generate a virtual card for online purchases, and if you lose your phone, you block it instantly through the app. None of this exists with a wad of bills.

When paying by card abroad, the machine may offer to "charge in reais". Always refuse and pay in the local currency: accepting the machine's conversion adds a 6% to 10% spread on top.

Cash and card, side by side

The decision becomes clear when both are put in the same table.

Note: the 3.5% IOF and the Visa network margin are verifiable; the tourist dollar spread varies by exchange bureau, estimated in typical market ranges as of July 2026.

The remaining balance does not need to become idle money. In the dollar account, it can continue to automatically earn yield in the Protected Stash (Caixinha Protegida), available for redemption at any time, instead of waiting for the next trip inside an envelope.

Checklist before traveling

The money part comes down to four decisions:

1. Know the threshold: $10,000 in cash. Above this, declare (e-DBV in Brazil, FinCEN 105 in the US). Declaring is free and does not tax anything.
2. Never divide the money among the group to evade the limit. In the United States, the limit is combined for the family or group traveling together, and splitting the money to stay below is structuring, an offense.
3. Bring little cash. A reserve of $100 to $300 for tips and emergencies is enough. Do not carry your entire budget in paper.
4. Concentrate the rest on the card. A card balance is not cash, does not enter the declaration, has no risk of theft, and, with a card with no IOF and no spread, costs close to zero.

In the end, the question "how much can I bring without declaring" has a better answer than a number: bring the minimum in cash and the rest on a card that pays no IOF, has no spread, and does not need to be declared at any border. Get to know the Picnic card before your next trip, or understand the product behind it in dollar account for Brazilians.

If your luggage doesn't arrive, also keep a reserve for essential purchases and save the receipts. See the step-by-step guide for lost luggage on an international flight.
