Strategic Tax Note: Under the German Finance Ministry's draft law, existing coins purchased on or before December 31, 2026 remain protected under grandfathering rules (Bestandsschutz), remaining completely tax-free once held past the 1-year threshold. Investors purchasing after December 31, 2026 lose the 1-year exemption entirely.
Regulatory Context & Legislative Status
- Breaking News Verification: German Finance Ministry proposal to replace § 23 EStG private sales exemption for crypto with a 25% flat tax (Kapitalertragsteuer) for acquisitions post-Dec 31, 2026 (CoinDesk original report).
- Current German Framework: Section 23 EStG treats crypto as private money/assets. Dispositions held over 365 days are completely tax-exempt. Short-term dispositions are taxed at personal progressive income tax brackets up to 45%.
- Legislative Pre-condition: The draft bill requires formal cabinet review, parliamentary approval from the Bundestag, and ratification by the Bundesrat before legal enactment.
