Tax with Foreign Brokers
IBKR-based brokers do not withhold German capital gains tax. BubbleTax automatically creates your tax report from FlexQuery data.
What's different about foreign brokers and taxes
Brokers like Interactive Brokers, Lynx, CapTrader, MEXEM and WH SelfInvest do not automatically withhold German capital gains tax – your capital stays invested longer. In return, you are responsible for reporting your capital gains in your tax return:
- •Gains and losses using the FIFO method (§ 20 Abs. 4 Satz 7 EStG)
- •Foreign currency gains from USD, GBP and other currency accounts
- •Dividends and creditable withholding tax under DTAs
- •Corporate actions like splits, spin-offs and tender offers
- •ETF advance lump sum and partial exemption under InvStG
