How much money can you bring to Spain and how to declare it (2026)
The Most Expensive Mistake You Can Make at Customs
What nobody tells you is that you don't need to be suspected of anything to have your money seized. All it takes is crossing customs with €10,000 or more in cash without declaring it for agents to take everything except €1,000.
The most common trap is thinking that if the money is yours and it's legal, no big deal. Wrong. The problem isn't the money. It's not declaring it.
Here's what a lot of people don't know — and what ends up costing them: the fine can reach double the amount you didn't declare. If you're bringing €15,000, the penalty can be €30,000.
The Limit: €10,000 in Cash
If you're entering or leaving Spain — or any European Union country — with €10,000 or more in cash, you have to declare it at customs. No exceptions, regardless of your nationality.
This also applies if you're carrying other currencies: what matters is the equivalent in euros.
"Cash" isn't just banknotes. It also includes coins, traveler's checks, bearer bank checks, non-personalized prepaid cards, and any other bearer payment method.
How Do You Declare the Money? The S1 Form
You need to fill out the S1 form, the official model from the Spanish Tax Agency (Agencia Tributaria). You've got two options:
- Online, before you travel, through the Agencia Tributaria's Electronic Office.
- On paper, by submitting it directly at the customs desk when you arrive at the airport or border crossing.
On the form, you'll need to include the exact amount, where the money came from, your destination, and the purpose of the transfer.
What Happens If You Don't Declare It?
The consequences are serious and they happen fast:
- Your money gets seized: agents can confiscate all the cash except €1,000, which they leave you for basic expenses.
- You get fined: penalties range from €600 (minor infraction) up to double the undeclared amount (very serious infraction).
- You get investigated: the money is held while the tax authorities look into where it came from. That can take months.
Quick Summary
| Amount you're bringing | What do you need to do? |
|---|---|
| Less than €10,000 | Nothing required (recommended to carry proof of origin) |
| €10,000 or more | Submit the S1 form at customs or through the Electronic Office |
The Safest Alternative: Bank Transfer
If you need to move a large amount of money to Spain, do an international bank transfer. It's safer, faster, and you don't need any customs forms.
Services like Wise, Revolut, or Remitly offer competitive exchange rates and low fees. No amount limits.
On top of that, the transfer automatically creates a paper trail. If the tax authorities ever ask you where the money came from, you've got proof without even having to look for it.
