From now on, anyone withdrawing €3,000 or more from a Spanish bank must notify the Agencia Tributaria (Spain’s tax agency) in advance. If you’re planning to take out €100,000 or more, you’ll need to give at least 72 hours’ notice. For smaller sums over €3,000, a 24-hour notification is mandatory.

Fail to notify? You risk a fine between 1 per cent and 10 per cent of the amount withdrawn — starting at €600 and climbing up to a massive €150,000, depending on the seriousness of the violation.
