Crypto Law/Level VIII · Around the world/8.2 Europe/Lesson 5

Spain

Spain supervises crypto firms through the CNMV under MiCA and taxes private crypto gains in the savings bands of income tax, with every swap a taxable event and a separate return for crypto held with custodians abroad.

Education, not legal, tax or investment advice. Crypto law differs between countries and states and changes often. Check the current rules where you live with a qualified lawyer or tax adviser before you act.

The lean path

The cheapest, lowest-tax, simplest and most private route the law allows, best first. Each step names the rule it rests on and the condition that keeps it lawful.

  1. Spain offers no holding-period exemption, so the lean lever is timing: realise gains in years with low savings income to stay in the lower bands of the 19% to 30% scale. Catch: every crypto-to-crypto swap is itself a taxable permuta.
  2. Realise losses against gains: under Article 49 of the IRPF law, net losses offset other gains, then up to 25% of savings capital income, carried forward four years. Catch: unused losses expire after the fourth year.
  3. Coins in a wallet whose private keys you control are outside Form 721, which covers only balances above EUR 50,000 held with foreign custodians at year-end. Catch: self-custody gains remain fully taxable and declarable.
  4. Record both coins’ market values at every swap, since the gain uses the higher value and the Agencia Tributaria applies first in, first out. Catch: Spanish providers report your balances and transactions on Forms 172 and 173.
  5. Use only providers authorised by the CNMV or another EU authority, which since 1 July 2026 are the only ones allowed to operate in Spain. Catch: an unauthorised provider leaves you without MiCA protection.

Wonder

  1. Is swapping bitcoin for another coin taxed in Spain even if I never touch euros?
  2. Do I have to report a hardware wallet on Form 721?
  3. Who can legally offer me crypto services in Spain after 1 July 2026?

  1. Spain’s securities regulator, the Comisión Nacional del Mercado de Valores (CNMV), is the competent authority for crypto-asset service providers under MiCA. Spain chose the full 18-month transitional period. The CNMV states that since 1 July 2026 only providers authorised by the CNMV or by another EU competent authority may operate in Spain, and warns that investors using unauthorised entities lose MiCA’s protections and supervision. It points users to the ESMA register and its own register to check a provider. Spain had already regulated crypto advertising through CNMV Circular 1/2022, published in the Official State Gazette (BOE) on 17 January 2022; the BOE now lists that circular as repealed.
  2. For individuals, the Agencia Tributaria treats a sale of crypto outside a business as a capital gain or loss in the savings base of personal income tax (IRPF). For 2025 the state half of the savings scale runs from 9.5% to 15%; combined with the matching regional half, the bands are 19%, 21%, 23%, 27% and 30%, with the 30% band applying to savings income above EUR 300,000. The gain is the difference between the transfer value and the acquisition value, imputed to the year in which the coins are delivered under the sale. Unlike Germany (lesson 8.2.3), Spain has no holding period after which gains become exempt.
  3. Swaps are taxed. The tax administration’s manual says that exchanging one virtual currency for a different one is a permuta, an exchange of goods under Article 1538 of the Civil Code, which produces a capital gain or loss under Article 37.1.h) of the IRPF law. The gain is measured against the higher of the market value of the coin given up and that of the coin received, and that value becomes the base cost of the new coin. The Directorate-General of Taxes took this view in binding ruling V0999-18 of 18 April 2018. For identical units bought at different times and prices, the manual applies first in, first out (FIFO).
  4. Spain adds information returns. Form 721, approved by an order published in the BOE on 29 July 2023, requires residents to report virtual currencies held abroad with providers that safeguard private keys for others, where the year-end balance exceeds EUR 50,000. The Agencia Tributaria’s FAQ says that coins in a wallet whose private keys the holder controls, whether hot or cold, are not covered, because they are not held by a custodian. Providers based in Spain file their own returns on customers’ balances (Form 172) and transactions (Form 173). A March 2026 draft order would add a new Form 175 for DAC8 reporting.
  5. Spain is behind on DAC8 (lesson 8.2.2). On 30 January 2026 the European Commission included Spain among 12 member states sent a letter of formal notice for failing to fully transpose Directive (EU) 2023/2226. The government’s bill amending the General Tax Law (Ley 58/2003), presented on 5 June 2025, would have partly transposed DAC8, added crypto-assets to the list of property the tax agency may seize, and created due-diligence duties for providers. It was still in committee when Royal Decree 806/2026, published in the BOE on 6 October 2026, dissolved Parliament and called elections for 29 November 2026. Bills pending at dissolution lapse, so the reform must be reintroduced.
  6. The dissolution also stopped a bill on financial-sector digitalisation, presented in July 2026, that according to press reports would have let the CNMV require crypto advertising to be changed, suspended or banned. Existing duties are unaffected: Forms 172, 173 and 721 still apply, and the tax rules above come from existing law rather than the lapsed bills. For holders, the practical consequence is that a Spanish resident’s crypto activity is already visible through domestic returns and, from 2026, through other states’ DAC8 exchanges. A practical check: before any swap, record both coins’ market values at that moment, and at each year-end total your balances held with foreign custodians against the EUR 50,000 Form 721 threshold.
