Tax-optimised investing for expats in Germany

Kapitalertragsteuer (KESt): 25% flat + 5.5% solidarity surcharge + church tax (if applicable). Withheld at source by German brokers on dividends, distributions and realised gains.

Sparer-Pauschbetrag: an annual tax-free allowance for investment income. €1,000 for singles / €2,000 for joint filers (since 2023). Activated by submitting a Freistellungsauftrag to your broker.

Teilfreistellung (partial exemption): a fixed share of fund income is tax-free to compensate for fund-level taxation. 30% for equity funds (≥51% equity), 15% for mixed funds, 60% for real-estate funds.

Since 2018, German investors pay an annual 'preliminary lump-sum tax' on accumulating funds, even without selling. The tax base is the lower of (a) the fund's actual price growth or (b) a notional return based on the Basiszins set by the Bundesbank.

Mechanics: notional return = invested value at start of year × Basiszins × 70%. KESt applies on that base, minus Teilfreistellung. The amounts are usually small but compound if ignored.

Practical: keep a cash buffer in your brokerage account in January, brokers automatically withhold Vorabpauschale and a negative cash balance triggers fees.

Accumulating vs distributing: in practice, the tax outcome is nearly identical for broad equity ETFs (both pay Vorabpauschale or distribution tax). Choose based on preference, not tax myth.

Domicile: Irish-domiciled ETFs are common for German investors thanks to the US-Ireland treaty (15% dividend withholding tax vs 30%). Luxembourg domicile is also common.

Aim for ≥51% equity allocation in core funds, the 30% Teilfreistellung is meaningful and lost on bond-heavy hybrids.

Submit a Freistellungsauftrag to every broker holding taxable assets. Split the €1,000 / €2,000 allowance across brokers in proportion to where income actually lands.

Without a Freistellungsauftrag, KESt is withheld in full and refunded only via the annual tax return, interest-free loan to the Finanzamt.

Couples filing jointly: a joint Freistellungsauftrag uses the full €2,000 even if all income sits with one spouse.

Default German behaviour is to defer: no forced sale, capital gains taxed only on disposal, Vorabpauschale is small.

Two situations where realising early is rational: (a) using unused Sparer-Pauschbetrag in low-income years; (b) the year before leaving Germany, locking in low-tax German treatment if your new country taxes gains harder.

Loss harvesting works but is segmented: equity losses can only offset equity gains, not bond or derivative gains. The 'Verlustverrechnungstopf' is broker-specific, losses don't auto-transfer.

Hold the bulk of equity exposure in plain ETFs in a depot, most portable, simplest tax treatment, easiest to move on.

Limit illiquid German-specific tax shelters (Riester, Rürup, certain bAV structures) to no more than you would be comfortable leaving behind if you moved.

When you do move: review unrealised gains 6-12 months ahead. In many cases, realising gains while still a German tax resident, under the 26.375% flat KESt, is better than the higher progressive rate in your new country.
