During tax declaration season, taxpayers in Spain who use cryptocurrencies must adhere to regulations if they do not want to be sanctioned by the tax authorities.

Key points:

- The firm specialized in cryptocurrency taxation, CL Cripto, offers recommendations for users.

- It is necessary for Spaniards to maintain an adequate and correct declaration.

- The Ministry of Finance handles a lot of information about Spanish taxpayers who use cryptocurrencies.


During this year's 2025 tax declaration campaign, Spanish taxpayers operating with cryptocurrencies face a strict regulatory environment. Spain requires users to report their movements with these digital assets under clear rules established by the Ministry of Finance.

Failure to comply with these obligations can lead to significant financial penalties. The Spanish Tax Agency (AEAT) has detailed information about operations conducted on national exchanges and associated bank movements, which facilitates the detection of irregularities. Therefore, an accurate declaration becomes essential to avoid legal issues and fines.

The Spanish firm specializing in cryptocurrency tax consulting, CL Cripto, offers 5 practical tips to ensure that users comply with the tax authorities. These suggestions aim to guide taxpayers in a context where the management of crypto assets is under the scrutiny of the country's fiscal authorities. The goal is clear: to avoid mistakes that could trigger inspections or penalties.

Below, it details how Spaniards can meet tax requirements without complications.

1. Keep a detailed record of all cryptocurrency transactions

To avoid problems with the tax authorities and comply with the requirements of the Spanish authorities, it is fundamental for taxpayers in that country to keep a thorough record of each operation conducted with cryptocurrencies, including purchases, sales, exchanges, income from staking, and any other relevant activity.

This record should contain dates, amounts, and values in euros at the time of the transaction. Management tools such as CoinTracking can facilitate this task and ensure accuracy in the declaration.

2. Take into account what the tax authorities already know about cryptocurrencies

Since last year, the tax authorities have a lot of information about crypto movements on Spanish exchanges, including information about each sale made. Additionally, they also have information on bank movements.

Therefore, when declaring, Spanish users must report everything that the tax authorities already know. Otherwise, it is very easy for the country's tax authorities to send letters requesting explanations for the discrepancies between what has been declared and what exchanges have reported about a user's crypto operations.

3. Plan tax operations

Periodically reviewing the tax position allows Spanish users to manage in advance the amounts they must declare and how to take advantage of periods of declines or losses to plan future crypto operations. This planning can help optimize the tax burden legally and efficiently.

Spanish users should also keep in mind that the payment for the Personal Income Tax (IRPF) can be made in two phases and without interest: the first, with 60%, by June 30. The remaining 40% in November.

It is important for users to also financially plan these payments, maintaining liquidity during those periods.

4. Offset losses and gains

If a Spanish user has incurred losses in some cryptocurrency trades, they can use them to offset gains made in the same tax year.

Additionally, if they have incurred losses in other assets, such as stocks, funds, or real estate, they can also offset these losses with gains from cryptocurrency investments.

Spanish taxpayers should also keep in mind that if they have losses from previous years, they have a total of 4 years to offset them with gains. Otherwise, they cannot be compensated.

5. Stay informed about tax updates

The tax regulations related to cryptocurrencies are constantly evolving. It is crucial for Spanish taxpayers to stay updated with the latest regulations to ensure compliance with all tax obligations.

Specialized websites, blogs, and webinars can be valuable sources of information.

Additionally, it is advisable to declare each cryptocurrency gain in the specific boxes determined by the Spanish tax authorities to avoid problems. So far, not all boxes for this year's income tax declaration are clear, but soon they will be known and one can start declaring in the exact boxes.

With these recommendations from the tax firm CL Cripto, cryptocurrency users in Spain can face tax declaration with greater confidence. The key lies in organization, transparency, and adapting to a constantly evolving regulatory framework. The tax authorities do not relent, and taxpayers must be prepared.
