BubbleTax.de — Automated, BMF‑compliant tax reports for IBKR traders in Germany.
BubbleTax is a project built by developers for developers and traders. Our mission:
- Import broker transaction data (especially IBKR) and generate tax reports that are compliant with German regulations (BMF writing as of May 2025).
- Handle complex cases: foreign‑currency conversion, FIFO lot matching, separation of different asset types (stocks, options, etc.).
- Offer a tool with trustworthy, transparent logic — clearly documented, no hidden fees, and with respect for users' needs.
