What to check before choosing a broker in Germany

Germany has a sophisticated financial system with strong BaFin regulation, excellent discount neobrokers, and a relatively straightforward flat-rate investment tax (Abgeltungsteuer). Here's what every German investor should know before opening a brokerage account.

1. BaFin authorisation is mandatory. All brokers operating in Germany must be authorised by BaFin (Bundesanstalt für Finanzdienstleistungsaufsicht), the Federal Financial Supervisory Authority. European brokers may also operate under their home regulator's licence via MiFID II passporting. Always verify authorisation at bafin.de. For EU-passported brokers, check the European Banking Authority's EUCLID register.

2. Abgeltungsteuer: a flat 25% withholding tax. Germany's Abgeltungsteuer is a final withholding tax at 25% (plus 5.5% Solidaritätszuschlag and, if applicable, Kirchensteuer) on all investment income — capital gains, dividends, and interest. The effective rate is approximately 26.375% (without church tax). German-based brokers automatically withhold and remit this tax on your behalf — you generally do not need to declare investment income separately on your tax return if all income was processed through a German broker.

3. Use your Sparerpauschbetrag every year. Every German taxpayer is entitled to a Sparerpauschbetrag of €1,000/year (raised from €801 in 2023; €2,000 for married couples). Submit a Freistellungsauftrag (exemption order) to your broker to apply this allowance — without it, the broker withholds Abgeltungsteuer on all investment income from the first euro. You can split this allowance across multiple brokers. Unused allowance cannot be carried forward.

4. Vorabpauschale for accumulating ETFs. Germany introduced a Vorabpauschale (advance flat-rate tax) on accumulating ETFs. Each January, a notional tax base is calculated on qualifying ETFs that did not distribute dividends. This simulates a minimum annual return and creates a tax event — even if you did not sell. UCITS ETFs with a Teilfreistellung (partial exemption) of 30% for equity ETFs, 15% for mixed funds, and 60% for real estate ETFs partially offset this. This is a key reason to hold accumulating ETFs inside tax-advantaged accounts or ensure you have cash available for the January Vorabpauschale payment.

What German Investors Need to Know in 2026

Germany's neobroker revolution has fundamentally changed retail investing costs. Trade Republic's flat €1/trade model and Scalable Capital's €0 PRIME+ subscription have commoditised trading. Meanwhile, interest rates on uninvested cash (4%+ at Trade Republic in recent years) made neobrokers competitive with savings accounts — though rates have moderated as the ECB cut rates through 2024–2025.

The Vorabpauschale has been a source of confusion since its 2018 introduction. The key rules: it applies to accumulating ETFs; it requires cash in your account each January; equity ETFs benefit from a 30% Teilfreistellung; and it is effectively a tax prepayment that reduces the gain on eventual sale. For buy-and-hold investors, this means accumulating ETFs are tax-efficient for long holding periods, but the annual January cash requirement must be managed.

Germany's 1-year crypto holding rule remains highly favourable by global standards — gains on crypto held more than 12 months are completely tax-free. This contrasts sharply with countries like the US (maximum 23.8% on long-term gains), the UK (18–24%), and France (30% flat). German crypto investors who understand this rule and hold through 12 months benefit from complete tax-free treatment.
