If you’re living in Spain, buying property, or managing international assets, it’s essential to understand the legal framework around handling large amounts of cash. Spain’s financial transparency laws have become increasingly strict — and failing to comply could lead to fines of up to €150,000.
Whether you’re planning to withdraw funds for a home renovation, transfer cash between accounts, or bring money into Spain from abroad, this guide explains what’s legally required — and how to stay on the right side of the law.
All Spanish banks are required to verify your identity for any cash transaction (deposit or withdrawal) over €1,000, even if you're an existing client. This includes showing valid photo ID or your NIE.
If you deposit or withdraw €3,000 or more in cash, your bank will automatically report the transaction to the Agencia Tributaria (Spanish Tax Agency). You do not need to do anything — but the origin of funds must be clear.
If you move €100,000 or more in cash within Spanish territory — for example, carrying it between cities or to a notary — you are legally required to file a Model S1 declaration with the Agencia Tributaria before the transfer. This applies to both residents and non-residents.
Anyone entering or leaving Spain with €10,000 or more in cash (or its equivalent) must declare this amount to Spanish Customs using the appropriate S1 form. This is part of Spain’s anti-money laundering compliance in line with EU regulations.
The financial penalties are steep and escalate based on the severity of the breach:
Minor Infringement: Up to 50% of the undeclared amount
Serious Offence: Between 50% and 100% of the amount involved
Very Serious Violation: Up to 150%, with fines reaching a maximum of €150,000
These rules are enforced under Law 10/2010 on the Prevention of Money Laundering and Terrorist Financing, and apply to both individuals and businesses.
