Tax filing with foreign brokers
IBKR-based brokers don't withhold German Abgeltungsteuer. You report capital gains yourself in Anlage KAP. BubbleTax handles the calculation under German law: FIFO, ECB rates, loss offsetting, every figure traceable back to the original transaction.
Five things every IBKR trader has to calculate for the German return
You pay for global market access and low fees with self-calculated tax. None of these five items is pre-filled anywhere:
Gains and losses under the FIFO method (§ 20 Abs. 4 Satz 7 EStG)
Foreign currency gains from USD, GBP and other currency sub-accounts
Dividends and creditable withholding tax under DTA
Corporate actions such as splits, spin-offs and tender offers
ETF Vorabpauschale and partial exemption under InvStG
