Crypto Taxes in Spain 2026: How to File Your Return Without Surprises

Spain’s tax agency (AEAT) has spent years cross-checking data with exchanges, and international cooperation through DAC8 and the CRS is tightening every year. If you hold crypto and live in Spain, filing correctly is no longer optional — it’s a matter of time. Here’s how crypto is taxed in the 2026 campaign.

The basic rule: when you actually owe

Buying bitcoin and simply holding it is not a taxable event. You only pay when there’s a disposal: selling crypto for euros, paying with crypto, or swapping one crypto for another (BTC→ETH counts too). Each disposal triggers a capital gain or loss — the difference between acquisition value and sale value.

That last point catches most Spanish investors: trading one token for another inside the same exchange creates a tax liability even though you never touched a euro.

The 2026 savings-bracket rates

Crypto capital gains go into the IRPF savings base, taxed in tiers:

• Up to €6,000: 19%
• €6,000 to €50,000: 21%
• €50,000 to €200,000: 23%
• €200,000 to €300,000: 27%
• Above €300,000: 30%

Capital losses offset gains within the same base, and unused 2025 gains carry forward under the general offsetting rules.

Which forms to file

Form 100 (IRPF). Your gains and losses from sales and swaps go here, along with movable-capital income: staking, lending, and interest are reported as income rather than capital gains.

Form 721. Informational declaration of crypto assets held abroad (offshore exchanges, self-custody wallets whose keys you control). Mandatory when the combined balance exceeds €50,000 as of December 31. Penalties for omitting it can dwarf the tax itself.

Form 714 (Wealth Tax). If your net wealth exceeds your autonomous community’s exemption threshold, crypto counts at year-end market value.

Common special cases

• Staking and airdrops: received tokens are valued at market price when received (a capital gain for AEAT), and selling them later creates a second gain or loss.
• NFTs and DeFi: every meaningful operation — swaps, liquidity positions, claims — can be a disposal. Traceability is everything.
• Inherited or donated crypto: different regimes (inheritance/gift tax or capital gains depending on the case); get advice before acting.
• Selling at a loss: yes, losses are deductible and they offset. But if you buy back something nearly identical days later, watch the anti-shuffling rules.

How to prepare your data (without losing your mind)

1. Download full history from every exchange: trades, deposits, and withdrawals as CSV.
2. Export your wallets using a block explorer or a tracking tool.
3. Apply one consistent valuation method — global FIFO is what most software uses and the most defensible position before AEAT.
4. Consolidate in one tool like CoinTracking, or hire a crypto-specialized advisor.
5. Keep your evidence for four years — the statute of limitations.

Bottom line

Crypto taxation in Spain in 2026 is less scary than it sounds: buy-and-hold costs nothing, sell-or-swap does, and offshore holdings get their own declaration via Form 721. The real risk isn’t the 19–30% rate — it’s not keeping records. Start exporting your histories today, before tax season becomes a race against the calendar.
