The Tax Office often feels intimidating, yet it serves a public purpose: funding essential services like health care and education through tax collection. Even so, many people feel uneasy when it is time to file their income tax return.
One major question around treasury and income declarations is how different transactions are taxed, how bank transfers are treated, and at what levels the authorities begin to scrutinize activity.
Advances in electronic banking have shifted how money moves. In recent years, tools have become more integrated into everyday banking, including Bizum as part of payment ecosystems. These methods enable the transfer of substantial sums quickly, sometimes within days or even moments, depending on the service used.
It is possible to transfer up to 500 Euros through Bizum; however, the reporting of these transactions for tax purposes can vary depending on the transaction type and the amount.

Border
Under the General Tax Law, banks are required to submit to the Tax Administration all kinds of data, reports, background information, and supporting documents relevant to tax obligations arising from financial activities or related to economic and professional relationships.
The amount that must be declared to the Treasury starts around 10,000 Euros: from this threshold, individuals are generally obliged to include it in their income tax returns.
Notice to those who receive fees above this threshold
Even though the mandatory declaration threshold is 10,000 Euros, authorities monitor all movements, and banks can be asked to provide data regardless of the total amount sent.
Sanctions
Taxpayers who report transfers exceeding 10,000 Euros are required to file the appropriate SI form. Sanctions can reach up to half of the amount sent, plus fixed penalties. Small fines may apply if the source of funds cannot be justified, and more serious penalties can occur for larger unaccounted amounts.
