Spain Forex Tax Calculator 2026

Forex CFD trading profits in Spain are classified as ganancias patrimoniales (capital gains) and taxed under the base del ahorro (savings income base) of the IRPF. The savings base uses five progressive tiers: 19% on the first EUR 6,000, 21% on EUR 6,001–50,000, 23% on EUR 50,001–200,000, 27% on EUR 200,001–300,000, and 28% above EUR 300,000. This is separate from the base general (earned income), which uses higher progressive rates.

The five-tier savings income brackets (base del ahorro) for 2025/2026 are: 19% on EUR 0–6,000, 21% on EUR 6,001–50,000, 23% on EUR 50,001–200,000, 27% on EUR 200,001–300,000, and 28% above EUR 300,000. The 27% and 28% tiers were introduced by the Presupuestos Generales del Estado 2023 (Ley 31/2022). These rates are national; autonomous communities cannot modify savings income rates.

Yes. Spain allows full offset of capital losses against capital gains within the savings base in the same tax year, with no annual cap. If your losses exceed your gains, the excess carries forward for four years. This is more generous than Germany (EUR 20,000 annual cap on derivative losses) but shorter than France (10-year carryforward) or Ireland (unlimited carryforward). Losses in the savings base cannot be offset against earned income in the base general.

Modelo 720 is Spain’s foreign asset declaration. You must file it by 31 March if, at any point during the year, your foreign assets exceed EUR 50,000 in any of three categories: bank accounts, securities/funds/insurance, and real estate. A trading account with a non-Spanish broker counts as a foreign bank account (Category 1) and potentially securities (Category 2). The European Court of Justice struck down the disproportionate penalties in Case C-788/19 (January 2022), but the filing obligation remains.

Forex CFD gains and losses are reported on Modelo 100 (IRPF annual tax return), specifically in the section for ganancias y pérdidas patrimoniales derivadas de la transmisión de elementos patrimoniales (capital gains from asset disposals). Each trade is a disposal. If your broker provides an annual statement with net gains/losses, you can report the aggregate. The filing deadline is typically 30 June. Foreign account holders must also file Modelo D-6 (securities held abroad) by 31 January if applicable.

Spain has the Impuesto sobre el Patrimonio (wealth tax), but rates vary by autonomous community — Madrid effectively exempts it via a 100% deduction, while Catalonia, Andalucía, and others apply rates from 0.2% to 3.5% on net assets above EUR 700,000 (with a EUR 300,000 primary residence exemption). Additionally, the national Impuesto Temporal de Solidaridad de las Grandes Fortunas (ITSGF) applies 1.7–3.5% on net wealth above EUR 3,700,000, regardless of community. Trading account balances count toward net wealth.

Spain’s effective rate depends on the amount: on EUR 6,000 or less, the 19% rate beats Germany (26.375%), France (30% PFU), Portugal (28%), and Italy (26%). But above EUR 50,000, the 23% tier exceeds Italy’s flat 26%, and above EUR 300,000, the 28% top rate approaches France’s PFU. Spain’s advantage is structural: no derivative-specific loss cap (unlike Germany’s EUR 20,000 limit), 4-year carryforward, and no social contributions on capital gains (unlike France’s 17.2% prélèvements sociaux built into the PFU).

This calculator applies to Spanish tax residents (residentes fiscales) filing IRPF. Non-residents are taxed under the Impuesto sobre la Renta de No Residentes (IRNR), typically at a flat 19% for EU/EEA residents or 24% for others, on Spanish-source income only. Forex gains from a non-Spanish broker are generally not Spanish-source, so non-residents often owe no Spanish tax on them. Consult an asesor fiscal for cross-border situations.
