Spain’s tax authority (Agencia Tributaria) is preparing sweeping changes in how instant money transfers are monitored. Starting February 2026, routine transactions via services like Bizum will cease to be anonymous for entrepreneurs and businesses. Every transfer linked to commercial activity will fall under close scrutiny from financial authorities.
Until now, banks were only required to report transfers if the amount exceeded €3,000. This allowed many small payments to fly under the tax authority’s radar. However, with the adoption of the new regulation, this threshold disappears. Any amount, if received as part of a business transaction, will now be recorded and reported.
New regulations
From 2026, financial institutions will begin providing the tax authority with monthly detailed reports on all transactions related to business activity. These reports will include information about account holders, merchant IDs, payment terminals used, total monthly receipts, and the account details receiving the funds.
The changes will primarily affect small and medium-sized businesses, as well as self-employed professionals. All income received for goods or services—regardless of the payment method, whether via Bizum, bank transfer, or card—will be subject to reporting. This also applies to those who use modern payment systems for transactions with clients.
Who is affected
Individuals who are not engaged in business activities need not worry: transfers between friends or relatives that are not related to business will not be included in reports. The tax authorities have specifically emphasized that the new rules do not affect personal transfers, provided they are not connected to income or capital gains.
However, if a transfer is related to rent payments, the sale of goods, or providing a service—even between private individuals—such transactions may be reviewed separately. In these cases, tax obligations are determined by the nature of the deal rather than the payment method.
Exceptions and details
There are other situations where banks are required to inform tax authorities. For example, if an individual withdraws more than 3,000 euros in cash or makes card purchases exceeding 25,000 euros per year, these transactions will also be included in the annual report.
Ordinary everyday transfers—such as splitting a dinner bill or collecting money for a gift—do not require declaration, as long as they are not related to commercial activity. However, regular incoming payments or large sums should be treated with caution: tax authorities may take an interest in the source of funds.
Preparing for changes
The decision to abolish the €3,000 threshold was made in April 2025. From that point, banks and tax authorities began working closely together to ensure a smooth transition to the new regulations. Over the course of the year, entrepreneurs and companies received guidance on how reporting procedures would change and what data would be transmitted.
Authorities emphasize that the goal of these changes is to combat tax evasion and increase transparency of financial flows. For most citizens not involved in business, nothing will change. However, entrepreneurs should prepare in advance for the new requirements and review their payment practices.
