Law 11/2021 of 9 July, on measures to prevent and combat tax fraud (BOE 10-7-21), establishes in Article 18 that transactions in which any of the parties involved acts as a businessperson or professional, for an amount equal to or greater than 1,000 euros (previously 2,500 euros) or its equivalent in foreign currency, may not be paid in cash.

However, the aforementioned amount shall be €10,000 (previously €15,000) or its equivalent in foreign currency, when the payer is a natural person who can prove that he does not have his tax domicile in Spain and is not acting in his capacity as a trader or professional.

This limitation will apply to all payments made after the entry into force of the rule (11 July 2021), even if they relate to transactions entered into prior to the establishment of the limitation.
