Cryptocurrency in Spain is treated as a digital asset, and tax is triggered when you realise a gain. Spain applies progressive savings income tax rates to crypto capital gains and progressive general income tax rates to crypto income such as mining or staking rewards.
In addition, Spain has strict reporting and wealth declaration requirements, including foreign asset reporting for holdings above €50,000, with significant penalties for non-compliance.
This guide explains how to legally reduce your crypto tax burden in Spain in 2026 through smart planning, timing, loss harvesting, accurate cost-basis tracking, and strategic reporting—and how Kryptos makes the process easier.
1. Capital Gains Tax on Crypto
When you sell, exchange, swap, spend, or otherwise dispose of crypto, you realise a taxable capital gain. These gains fall under savings income in the Spanish tax system.
Progressive savings income tax rates:
- Up to €6,000 → 19%
- €6,001 – €50,000 → 21%
- €50,001 – €200,000 → 23%
- €200,001 – €300,000 → 27%
- Over €300,000 → 28%
These rates apply to:
- Selling crypto for euros
- Crypto-to-crypto swaps (taxable disposals)
- Using crypto to purchase goods or services
2. Income Tax on Crypto Rewards
Crypto received as income is taxed under IRPF general income tax rates, which can reach ~47%, depending on total income and region.
Taxable income includes:
- Mining rewards
- Staking rewards
- Airdrops
- DeFi yields
- Referral bonuses
- Salaries paid in crypto
3. Cost Basis and FIFO Method
Spain mandates the FIFO (First-In, First-Out) method for calculating cost basis.
- The oldest units acquired are treated as sold first
- Incorrect FIFO tracking often leads to overstated gains
Accurate FIFO records are essential for minimising tax.
4. Reporting Requirements
IRPF (Modelo 100)
- All realised crypto gains, losses, and income must be reported on the annual income tax return (Modelo 100).
Modelo 721 – Foreign Crypto Holdings
- If crypto held abroad exceeds €50,000 in total value on December 31, you must file Modelo 721.
- Filing window: January 1 – March 31 of the following year.
Wealth Tax (Impuesto sobre el Patrimonio)
- Crypto counts toward total net wealth.
- Wealth tax may apply if assets exceed regional thresholds (often €700,000, before exemptions).
1. Harvest Capital Losses Within the Same Year
Strategy:
- Realise losses on underperforming crypto before year-end
- Offset losses against gains realised in the same year
- Reduce your net taxable capital gain under savings income rules
This directly lowers the progressive capital gains tax you owe.
2. Time Disposals Around Income Levels
Because both capital gains and crypto income are taxed progressively:
Strategy:
- Plan large disposals in years when your overall income is lower
- This can keep you in a lower tax bracket for both income and capital gains
3. Track Cost Basis Accurately (FIFO Required)
Spain strictly enforces FIFO.
Strategy:
- Track acquisition date, purchase price, and fees for every crypto purchase
- Convert all transactions into euros at the transaction date
- Maintain consistent, complete records
Accurate FIFO tracking can significantly reduce taxable gains.
4. Use Tax-Free Events to Defer Tax
The following events are not taxable by themselves:
- Buying crypto with fiat
- Transferring crypto between wallets you own
- Holding crypto without disposal
Strategy:
- Avoid unnecessary sales late in the year
- Group disposals strategically when tax optimisation is possible
5. Separate Crypto Income From Capital Gains
Income events are taxed differently from investment gains.
Strategy:
- Record income at fair market value on receipt
- Track income events separately from capital disposals
- Avoid mixing staking or reward income with capital gains calculations
Correct classification prevents overpayment.
6. Plan Around Wealth and Foreign Reporting Thresholds
Modelo 721 and wealth tax rules increase compliance obligations.
Strategy:
- Monitor year-end foreign crypto holdings
- Stay below the €50,000 threshold where feasible to avoid Modelo 721
- Apply regional exemptions (e.g., Madrid’s wealth tax benefits), if applicable
This reduces reporting complexity and penalty risk.
7. Keep Full Audit-Ready Documentation
With expanding EU and Spanish reporting requirements, documentation is critical.
Keep records of:
- All transactions
- Wallet transfers
- FIFO cost basis calculations
- EUR valuations
- Staking and income receipts
Strong documentation protects you in audits and disputes.
- Not harvesting losses effectively
- Miscalculating FIFO cost basis
- Ignoring income vs capital gains classification
- Failing to file Modelo 721 when required
- Forgetting wealth tax reporting
- Treating taxable swaps as non-taxable
These mistakes often lead to overpayment or penalties.
