There are 3 factors that allow anyone to respond effectively to the Spanish Treasury.
“Disorder is what complicates your life,” warns tax advisor Jesús Lorente.
The increase in tax surveillance in Spain has led to a massive sending of notifications and letters to taxpayers who transacted with bitcoin (BTC) and cryptocurrencies during the 2025 financial year.
Through these communications, the Treasury seeks to request additional information or clarify operations carried out with digital assets that may not have been properly reported.
In this situation, the doubt arises about what to do and how to act. Precisely there, transparency and technical preparation They become the best defenses for the Spanish citizen that uses cryptocurrencies.
Jesús Lorente, partner at the firm specializing in cryptocurrency taxation CL Cripto and advisor specializing in taxes on digital assets, warns that the natural human reaction of freezing when receiving a letter from the treasury must give way to organized action.
The analyst explains that There are three fundamental pillars to respond effectively: prepare a clear document with the complete operation, carefully match the movements with the final balances – through the use of specialized software such as CoinTracking – and respond in a rigorous order.
The key to this process lies in traceability. Lorente insists that “disorder is what complicates your life” during a Treasury inspection. In his opinion, a taxpayer who has organized documentation can change completely the tone of the conversation with the Spanish Treasury.
On the contrary, the lack of clear records generates haste, inconsistencies and incomplete explanations which usually lead to greater administrative complications, Lorente warns.
This supervision process occurs immediately upon receipt of the notification, a critical period especially for those who have operated on multiple platforms, exchanges or cold wallets.
The specialist indicates that The reconstruction of financial activity is a demanding technical taskbut necessary to demonstrate the veracity of the declared balances and avoid suspicions of concealment of information.
On April 8, the Income 2026 campaign began, which represents the consolidation of automated control over bitcoin and other digital currencies in Spain.
And while thousands of taxpayers render accounts for the 2025 financial year, the Tax Agency has activated a massive data crossing backed by artificial intelligence (AI) algorithms, closing the siege on an ecosystem that was previously perceived as opaque, as reported by CriptoNoticias.
In this new scenario, the real risk for the bitcoin holder has shifted from market volatility to regulatory compliance through various forms.
Form 100, corresponding to the Income Tax Return, requires including any capital gain or loss derived from exchanges or sales. On the other hand, Form 721 is the specific informative declaration for digital currencies located abroad, mandatory for balances greater than 50,000 euros as of December 31.
Likewise, large estates must consider Model 714, relating to the Wealth Tax, where digital assets must be computed at their market value.
This environment of scrutiny requires absolute documentary precision to protect the profitability of the investment against the demands of the treasury.
Therefore, when faced with a request from the Treasury, emotional management must be replaced by a strategy based on order. As Lorente’s experience points out, impeccable traceability It is usually the strongest tool to resolve any tax discrepancies without facing penalties.
