Taxes are the biggest return killer after costs. 26.375% withholding tax on every capital gain — it adds up. But there are legal ways to significantly reduce the tax burden.

Strategy 1: Fully Use Tax-Free Allowance

1,000 euros of capital gains per person (2,000 for couples) are tax-free. Set up a tax exemption order at every broker — proportional to expected returns.

Strategy 2: Use Accumulating ETFs

With distributing ETFs you immediately pay taxes on dividends. With accumulating ETFs, dividends are reinvested — you only pay a small advance lump sum. Most taxes are deferred to the sale date — maximum compound effect on the tax amount.

Strategy 3: Loss Harvesting

Realized losses can be offset against realized gains. At year-end: Check if losing positions exist that you can realize — and repurchase the next day. You realized the tax loss without actually giving up the position.

Strategy 4: Request Favorable Assessment

If your personal income tax rate is below 25%, you can request favorable assessment in your tax return. Capital gains are then taxed at the lower personal rate.

Strategy 5: Use Children Depot

Every child has their own tax-free allowance (1,000 euros) AND basic tax allowance (11,604 euros). Up to 12,604 euros of capital gains completely tax-free per child.

Strategy 6: Timing of Gain Realization

Within tax-free allowance: Realize up to 1,000 euros in gains annually (tax-free), sell and immediately repurchase. This raises your cost basis and reduces future tax burden.
Sabbatical/Parental leave: In years with low income, capital gains are taxed more favorably.

Strategy 7: Crypto Holding Period

Cryptocurrencies held longer than 1 year are tax-free in Germany. The only completely tax-free capital gain in Germany.

What Does NOT Work

Tax evasion: Illegal and will be detected (automatic information exchange CRS)
Offshore accounts: Reporting obligation, high penalties for non-reporting

Bottom Line: Tax optimization is not fraud — it is the use of legal possibilities. Every saved tax euro is one more euro of return. And over 30 years of compound interest, that euro makes an enormous difference.
