Did you know that if you’re entering or leaving Spain with a large amount of money, you need to declare it to Spanish authorities? And what happens if you want to do the same within Spain when you're moving regions for example? There is a higher threshold when moving money within Spain. Purpose of the transfer – Why are you moving this much money to Spain? If you’re moving money within the country equal to or greater than €100,000, you must submit a declaration electronically to AEAT rather than downloading and completing the S-1 form.
