Ordinary resident capital gains
Under Spain’s ordinary common-territory rules, crypto sale gains from private transactions outside an economic activity form part of savings income. The combined state and regional marginal savings bands are 19% to €6,000; 21% from €6,000 to €50,000; 23% from €50,000 to €200,000; 27% from €200,000 to €300,000; and 30% above €300,000. The bands apply to the relevant savings base, not separately to each coin or exchange account. The current consolidated IRPF provisions retain the scale introduced from 2025.
The Basque Country and Navarra operate separate foral tax systems. Obtain the applicable local assessment rather than automatically applying this common-territory scale there.
A swap is not tax-neutral
An exchange of one virtual currency for another is a taxable barter transaction under AEAT’s guidance. Its valuation uses the specific barter rules, so no cash-out is needed for a gain or loss to arise. Homogeneous units are identified using FIFO, and euro valuations, acquisition records and directly related costs must be kept. The timing of delivery or exchange matters; delaying the receipt of fiat sale proceeds does not itself defer the gain. These rules address private disposals, not the classification of every reward or service receipt.
Foreign-custody reporting is separate from the tax bill
Modelo 721 can apply where virtual currencies are held through qualifying foreign third-party custodians. The general initial test is an aggregate year-end balance exceeding €50,000, subject to the detailed exemptions. Assets whose private keys the owner controls without a qualifying custodian are outside this particular reporting definition; that does not exempt their income or gains from tax.
The normal filing window is 1 January to 31 March of the following year. Later declarations can be required after an aggregate increase of more than €20,000 over the balance that triggered the previous filing, and specified disposals or cessations can also require reporting.
Residence and taxes on wealth
Ordinary Spanish tax residents are generally assessed on worldwide income, subject to treaties. Residence is not settled solely by counting days: economic interests and relevant presumptions also need review. Spain normally treats residence status for the calendar tax year rather than granting a simple UK-style split year.
Crypto holdings can enter the Wealth Tax calculation. The solidarity tax on large fortunes is a separate consideration; regional rules, exemptions, deductions and the interaction between the two need a household-specific review. A CGT-only comparison can therefore miss a material annual cost.
The inbound-worker regime is not a seven-year crypto deal
Spain’s Article 93 regime is potentially available for the arrival tax year and five following tax years, subject to eligibility and election requirements. It is not a residence-by-investment benefit or an automatic crypto exemption. A proposed crypto position under that regime needs advice on the taxpayer’s eligibility, the nature of each receipt and its source; this page’s 19%–30% comparison describes ordinary resident private gains.
