Investment Taxation in Europe: Capital Gains, Dividends and Crypto in 2026

How Is Investment Income Taxed Across the EU?

There is no single EU-wide capital gains tax. Each member state sets its own rates and rules. That said, four large markets dominate the conversation for retail investors. Italy applies a flat 26% imposta sostitutiva on capital gains, interest and dividends, with a separate 12.5% rate on government bonds. Germany levies a 25% Abgeltungsteuer (withholding tax) plus a 5.5% Solidaritätszuschlag surcharge, giving an effective rate of around 26.375%. Spain uses a progressive savings income tax (IRPF) ranging from 19% on the first €6,000 of gains up to 28% on gains exceeding €300,000. France applies a 30% prélèvement forfaitaire unique (PFU), also called flat tax, combining 12.8% income tax and 17.2% social charges — though taxpayers can opt for the progressive income tax scale if it is more favourable. Dividends from foreign stocks are typically subject to withholding tax in the source country and must be declared again in the country of residence, though double taxation treaties usually provide a credit or exemption. Understanding these rates is the first step; keeping accurate records is the second.

How Are Capital Gains from Trading Taxed in Italy, Germany and Spain?

Italy's regime is among the clearest in Europe. Capital gains from the sale of shares, ETFs, funds and bonds held outside of a pension plan are taxed at a flat 26% imposta sostitutiva. Under the regime dichiarativo (self-declaration), investors calculate and pay the tax themselves via the annual income tax return. Under the regime amministrato (administered), an Italian broker automatically withholds the tax on each transaction. One important feature is the carry-forward of losses: capital losses can offset gains of the same category for up to four subsequent tax years, making tax-loss harvesting a legitimate and widely used strategy. Germany operates similarly with Abgeltungsteuer. Each German broker applies the tax automatically, and a Freistellungsauftrag (exemption order) of up to €1,000 per year per person (€2,000 for married couples filing jointly) exempts the first tranche of investment income from tax. Losses within the same broker can be offset against gains; losses across different brokers require a manual annual declaration (Verlustverrechnungstopf). Spain requires all capital gains to be declared in the annual IRPF return regardless of amount. The progressive rate (19%, 21%, 25%, 28%) applies on net gains after offsetting losses. Losses can be carried forward for four years. Non-residents in Spain pay a flat 19% IRNR rate under most double taxation treaties.

How Is Crypto Taxed in Europe? Italy, Germany and Spain Compared

Crypto taxation has been the most rapidly evolving area of European investment tax law. Italy's 2023 budget law (Legge di Bilancio 2023) established a definitive framework: crypto gains above €2,000 per year are taxed at 26%. Crypto holdings above €15,000 at any point during the year must be disclosed in the quadro RW section of the income tax return (Modello Redditi PF), even if no gain was realised. Crypto-to-crypto swaps are generally taxable events. Germany retains one of the most investor-friendly rules in Europe: crypto held for more than one year is completely exempt from capital gains tax. For holdings below one year, gains are taxed as personal income (progressive rates up to 45%). This makes Germany particularly attractive for long-term holders. Spain issued binding guidance (consultas vinculantes) classifying all crypto disposals as capital gains subject to IRPF. Additionally, since 2023, Spanish residents with crypto assets worth more than €50,000 held on foreign exchanges must file the Modelo 721 declaration — a new and strictly enforced reporting form. France treats crypto gains at the flat 30% PFU. Gains are calculated on each disposal event. Losses from crypto cannot be offset against gains from other asset classes. Taxpayers must declare via the Cerfa 2086 annex to the income tax return.

What Records Do You Need to Keep for Investment Tax Reporting?

Accurate record-keeping is the foundation of compliant investment tax reporting. For each taxable event — a sale, a dividend payment, a crypto swap, or a currency conversion — you need to know the date of the transaction, the asset name and ISIN (for securities), the quantity bought and sold, the acquisition cost (including brokerage commissions), the proceeds, the gain or loss in local currency, and the exchange rate if the transaction was in a foreign currency. Most brokers provide annual tax statements, but these are often incomplete for multi-broker investors or for crypto. Italian investors in the regime dichiarativo must compute all gains and losses themselves. German investors using foreign brokers receive no automatic Freistellungsauftrag benefit and must declare everything manually. DonkyCapital aggregates transaction data from multiple brokers via CSV import and API connection, calculates your realised and unrealised gains, and lets you export a clean transaction history formatted for tax reporting — saving hours of spreadsheet work at year end.

How Do You Minimize Legal Tax Liability on European Investments?

Legal tax minimisation strategies are well-established and widely used by informed European investors. Tax-loss harvesting — deliberately selling positions at a loss to offset taxable gains — is legal in Italy, Germany and Spain, though each country has slightly different rules on what can be offset against what. Timing matters: in Italy, for example, selling a losing position before year-end allows the loss to offset gains already realised during the same year. In Germany, losses on shares cannot be offset against gains on other instruments (interest, dividends) — only against equity gains. Pension and retirement vehicles offer significant deductions. Italian PIR (Piani Individuali di Risparmio) exempt gains from tax entirely if held for at least five years, subject to concentration limits. German Riester-Rente and Rürup-Rente contributions are tax-deductible. French PEA (Plan d'Épargne en Actions) exempts gains from income tax (though social charges still apply) after five years. Spanish PIAS (Planes Individuales de Ahorro Sistemático) and pension plans (Planes de Pensiones) offer deductions on contributions. Using tax-advantaged wrappers systematically, combined with loss harvesting and optimal holding periods, is the most effective legal approach to reducing the tax drag on a European investment portfolio.
