German Investment Tax Tracker
Free calculation tool (Rechenhilfe) for German investment taxes on ETFs and funds held at foreign brokers like DEGIRO, Interactive Brokers (IBKR), and other non-German banks.
This is experimental software and not professionally audited tax software. Treat all outputs as preliminary and verify them independently before filing.
What this tool calculates
- Vorabpauschale — deemed income tax on fund value increases, calculated yearly using the official Basiszins
- Teilfreistellung — partial tax exemptions by fund type (30% Aktienfonds, 15% Mischfonds, 60% Immobilienfonds)
- Anlage KAP-INV values — main lines for distributions, Vorabpauschale, and fund sales, with manual line-53 handling in the sale wizard
- Anlage KAP reference values — supported today for Zeilen 17, 19, 20, 21, 22, 23, 24, 40, 41 and 42 where the app has explicit matching inputs
- Fund sale gains/losses — purchase cost basis tracking with a manual KAP-INV line-53 sale adjustment
Who is this for?
German tax residents who hold ETFs or funds at foreign brokers that do not automatically withhold German Abgeltungsteuer. If you use DEGIRO, Interactive Brokers, Trading 212, Scalable Capital (non-German entity), or similar foreign brokers, you need to report Vorabpauschale and capital gains manually in your Steuererklärung.
Features
- Multi-year tracking (2023-2026)
- Multiple fund support with different fund types
- Sale wizard with purchase cost basis and Vorabpauschale offset
- ELSTER reference output for the currently supported KAP-INV and KAP lines
- Best suited for post-2018 holdings; pre-2018 old-share cases and same-year ETF/fund round-trips are not yet modeled
- Your tax data stays in your browser, but the site still loads basic analytics
