Crypto Tax in Spain 2026: 19-30% Rate, Forms & Deadlines

Taxation of cryptocurrencies in Spain

In Spain, capital gains on cryptocurrencies are subject to tax. The calculation method used is FIFO with a rate of 19-30%. Understanding these rules is essential to stay compliant with tax legislation.

The FIFO method explained in detail

The First-In-First-Out (FIFO) method considers that the first assets purchased are the first sold. The gain is calculated on the difference between the sale price and the purchase price of the oldest lot.

Taxable events

• ●Sale of crypto for fiat currency (EUR, USD...)
• ●Payment for goods or services with cryptocurrencies
• ●Crypto-to-crypto swap (e.g. BTC → ETH)
• ●Converting to a stablecoin (USDT, USDC…)
• ●Receiving staking rewards: taxable as income at the time of receipt
• ●Airdrops and free tokens: generally taxable at the value upon receipt
• ●Mining income: taxable as business income or miscellaneous income
• ●Crypto-to-crypto exchange (in some countries only)
• ●Transfer between your own wallets
• ●Holding (HODL): holding without selling does not create any tax obligation (except in the Netherlands, Box 3)

Tax declaration procedure in Spain

You must declare your crypto capital gains on the following forms: Modelo 100, Modelo 720/721. We recommend keeping the complete history of your transactions as proof.

Exemption thresholds and allowances

In Spain, there is currently no specific exemption threshold for crypto capital gains. This means that any capital gain, however small, is theoretically taxable. It is therefore important to declare all of your gains.

Deadlines and tax calendar

Each EU country has its own tax filing deadlines. In Spain, the income tax return (including crypto capital gains) must generally be filed between April and June of the following year. We strongly recommend preparing your crypto tax return in advance with Taxes Crypto rather than waiting until the last moment.

Penalties for non-declaration

Failing to declare your crypto capital gains can lead to significant penalties: tax surcharges (10% to 40%), late-payment interest, and in serious cases, criminal prosecution for tax fraud. With DAC8 (2026), Binance automatically transmits your data to tax authorities, making detection of non-filers virtually automatic.

Tax treatment of crypto-to-crypto exchanges

In Spain, a crypto-to-crypto swap (e.g. BTC → ETH) is a taxable event: the gain is computed at each swap, even without converting to fiat. Every transaction must therefore be tracked and valued.

NFTs, DeFi and derivatives

In Spain, NFTs are generally treated like other crypto-assets: selling at a gain is taxable under the applicable regime (19-30%). DeFi income (staking, lending, yield farming) and derivatives (futures, options) are also taxable, each under its own regime. Regularly creating or selling NFTs may qualify as a professional activity.

Obligation to declare crypto accounts and wallets

As a resident of an EU country like Spain, you generally must declare digital-asset accounts held on foreign platforms. Under the DAC8 directive, automatic exchange of information between tax authorities becomes the norm from 2026.

Practical calculation examples in Spain

In Spain, a taxable gain of 10,000 € is added to your other income for the year. It is then taxed at your marginal rate (19-30%), not a single flat rate.

Tax calendar and key dates in Spain

In Spain, your crypto gains are usually filed by June for the previous year, via Modelo 100, Modelo 720/721. Gather your statements early to meet this deadline.

Specific tips for Spain

Crypto taxation in Spain has certain specificities that are important to know. The FIFO calculation method imposes a precise logic for determining the order of disposals. Investors should be particularly vigilant about the following: crypto-to-crypto exchanges may be taxable depending on the jurisdiction, airdrops and hard forks have specific tax treatment, and staking or mining income is generally considered taxable income upon receipt. In case of a change of tax residence, the rules of your new country apply for future transactions, but unrealised gains may be subject to an exit tax in certain cases. Consult a tax professional if your situation is complex.
