Spain to require crypto reporting under Model 720

Tax authorities will mandate reporting of all crypto operations

On October 19, 2018, the Council of Ministers approved an anti-fraud bill draft, confirming antiestéticars among Spanish crypto users: holders of bitcoin or other virtual currencies must report their transactions to the Agencia Tributaria. Finance Minister María Jesús Montero summarized it as identifying owners and balances of these virtual assets. The Modelo 720, the annual declaration for foreign-held assets, now covers cryptocurrencies stored outside Spain.

The news hit hard those who had invested savings in virtual currencies assuming no oversight. Initial reactions included small wallets selling before year-end, while others scrutinized the text for loopholes before it became law.

What exactly changes in the Treasury draft

The text imposes two obligations. Individuals and companies must report virtual currency operations to tax authorities, and those holding crypto custodied abroad must include it in the Modelo 720. In practice, the administration seeks to know who holds what and where, even if 'where' is a server on the other side of the world.

This reveals a gap in the official narrative. Many argue the trail already exists without new rules: buying bitcoin involves bank transfers recorded by banks and the government. However, this only proves a purchase, not current ownership. Once moved to a personal wallet, the trail disappears.

Montero emphasized that the obligation applies to both individuals and businesses, targeting all operations, not just large ones. Details on how to declare coins not held in banks remain unresolved.

How much tax do you pay selling bitcoin in Spain?

Capital gains in the IRPF are taxed between 19% and 23% depending on the bracket, compared to 1% within a SICAV fund. This comparison highlights the framework: individual investors pay tax on profits but receive no relief when positions lose value.

A common conclusion emerges: if I win, they take a quarter; if I lose, I bear it. This asymmetry drives many toward non-declaration, though explaining how to buy property with unreported bitcoin remains difficult.

Trading also triggers taxes, not just fiat conversion

The most troubling aspect wasn't converting to euros. It was everything else. Each crypto-to-crypto swap can be considered a transfer with gain or loss, requiring FIFO or LIFO methods. Using bitcoin to access another coin—due to lack of direct pairs—could create a taxable event without seeing any euros.

Calculating this across micro-transactions on defunct platforms creates a labyrinth many deem impossible to reconstruct. Yet, what cannot be reconstructed cannot be justified either.

Monero, Dash, and unregistered exchanges: the anonymity route

Facing scrutiny, many chose movement over declaration. A circulating recipe involves isolated wallets, privacy-enhanced coins, inter-wallet transfers, and returning to clean bitcoin. The cost includes fees and total trust in unregistered intermediaries.

An uncomfortable question arises: if an exchange cooperates with tax authorities, IP addresses, emails, and phone numbers map the entire network. If the exchange is in a non-cooperative country, the map vanishes.

Why some hold despite price surges?

Behavioral factors outweigh fiscal ones. Speculative markets show average investors sell early on small gains and hold through large ones. At the announcement date, 1,000 bitcoins were worth approximately €6 million.

The figure is identical for all, but responses differ. Declaring such wealth at 25 differs from doing so at 58 with family responsibilities. Some advocate partial declaration; others warn this paints a target on oneself.

Japan and Canada move in opposite directions

International comparisons emerged quickly. Japan works to simplify crypto tax filings, while Canada allows bitcoin spending via prepaid Visa cards. Meanwhile, Spain debates fitting everything into one form.

Portugal appears as a fiscal exit option, though documentation requirements for euro conversions remain unclear. The core question persists: is blockchain anonymity real, or does it last only until the next regulatory change.
