Learn how to declare cryptocurrencies in Spain using Forms 172, 173, and 721 to avoid fines and comply with the Treasury.
The digital age has profoundly transformed the concept of money and wealth, placing cryptocurrencies at the center of a global financial revolution. This transformation, however, has not gone unnoticed by tax authorities seeking to adapt their systems to the new economic landscape.
For those who trade digital assets in Spain, knowing and complying with tax obligations is vital to avoiding penalties. Tax forms 172, 173, and 721 have been established as key tools for declaring cryptocurrencies, and their compliance is now mandatory.
EXPLORE THE POTENTIAL OF CRYPTOThe importance of declaring cryptocurrencies and the arrival of forms 172, 173, and 721
The growing interest in cryptocurrencies has led Spanish regulators to strengthen their tax control mechanisms to prevent fraud and ensure transparency. Starting in 2024, and fully effective for tax returns in 2025, the Spanish government requires cryptocurrency holdings and transactions to be declared using three specific forms: Forms 172, 173, and 721. These forms collect detailed information on balances, transactions, and cryptocurrencies held abroad, reflecting a significant change in the tax treatment of these digital assets.
Form 172 focuses on the balance of virtual currencies held by companies with tax residence in Spain, particularly when the profits derived from these currencies exceed €1.000. Form 173, meanwhile, collects more specific information on transactions, detailing the identity of those conducting the transactions, the currency used, the amounts traded, and the value and date of the transactions.
Finally, Form 721 is intended to report cryptocurrencies located outside of national territory, a key requirement for those who hold digital assets on foreign exchanges or wallets. Its imposition responds to a clear strategy to combat tax fraud and evasion, which, in the past, has found fertile ground in opacity and a lack of regulation, as explained by digital advisor @CeroUnoCrypto.
Who must file tax forms and what do they entail?
The obligation to file these forms applies to both individuals and legal entities that hold or operate cryptocurrencies, although there are important nuances depending on the type of taxpayer and the volume of assets. For companies resident in Spain, filing Form 172 is essential if the profit on virtual holdings exceeds €1.000, while Form 173 requires a detailed breakdown of each transaction.
Regarding Form 721, the law establishes a threshold: reporting is only mandatory if the total balance of cryptocurrencies held abroad exceeds €50.000, meaning that this return does not need to be filed for smaller amounts. However, this rule does not exempt you from the obligation to declare these holdings for personal income tax purposes or to keep rigorous accounting records.
These tax requirements seek not only to raise awareness of cryptocurrencies both within and outside of Spain, but also to include related activities, such as mining or private key custody services. Furthermore, the State has made it clear that it may intervene directly in digital assets to settle tax debts, underscoring the importance of maintaining compliance and avoiding penalties.
ENTER CRYPTO HERETechnical and administrative details of the models
To comply with the new obligations, it is essential to know the content and elements that make up each declaration. Form 172 requests, among other data, the annual balance of digital assets, while Form 173 increases the level of detail by requesting a breakdown of each transaction: who carried it out, the cryptocurrency involved, the amounts, dates, and values in euros. Form 721 goes further, requiring personal information such as name and NIF (Tax Identification Number), as well as information on the custodian of the assets, the balances broken down by cryptocurrency, and their valuation in euros as of December 31.
These forms have been designed to allow the Tax Agency to cross-reference data and detect inconsistencies or irregularities in the declaration of cryptocurrency holdings and transactions. Filing is done through official Treasury channels. Failure to comply or providing incorrect data can result in substantial fines and penalties.
Tax Impact and Penalty Risk: How to Protect Yourself
Properly and timely declaring cryptocurrencies is not only a legal issue; it also protects taxpayers from penalties that can range from financial fines to seizures of digital assets. The complexity lies in the fact that each transaction may be subject to specific taxation, and accurate valuation in euros is crucial to avoid errors. For example, the constantly changing value of cryptocurrencies requires correctly reflecting the value of each transaction on the date it was made.
It is essential to maintain comprehensive records of all transactions, including purchases, sales, exchanges, mining revenues, and any other transactions. This control will not only allow for compliance with Forms 172 and 173, but will also facilitate the correct filing of Form 721 if assets are held abroad.
Furthermore, ignorance or negligence in filing a tax return can trigger legal mechanisms that allow the Treasury to seize cryptocurrency to settle outstanding tax debts. This reality highlights the need to seek proper advice and use tools that simplify cryptocurrency accounting.

The regulatory future and its influence on cryptocurrency holders
The Spanish tax framework is constantly adapting to keep pace with technological and financial innovation. Thus, the implementation of these models is not just a one-time requirement, but the beginning of a deeper regulatory process that seeks to integrate cryptocurrencies into the tax system in a clear and transparent manner. At the European level, regulations such as MiCA (Markets in Crypto-Assets) aim to harmonize the control of digital assets throughout the Union, strengthening legal certainty and protecting users.
For cryptocurrency holders, the recommendation is clear: stay informed, keep your accounting records in order, and comply with new tax obligations to avoid legal issues and maintain trust in the crypto ecosystem. Transparency and accountability are, more than ever, the foundation on which the future of digital finance is being built.
Adapt to regulation
Adapting to the new tax regulations on cryptocurrencies is a challenge faced by both individuals and legal entities in Spain. Forms 172, 173, and 721 are here to stay, creating a system that requires greater control and detail in the declaration of these digital assets. Knowing the specific characteristics of each one, understanding when and how to file them, and keeping meticulous records of transactions is essential to avoid fines and penalties.
The current scenario requires investors and cryptocurrency holders to be aware of their tax responsibilities and act accordingly. Those who stay informed and comply with regulations will be able to enjoy the advantages offered by the crypto world without unpleasant surprises. Ultimately, the key to navigating this new financial environment lies in transparency, organization, and education.
