The Problem

Foreign brokers do not issue a German annual tax certificate.

Anyone investing with DEGIRO, Interactive Brokers, eToro, XTB, Trading 212 or other foreign brokers receives no German tax certificate at year end — unlike comdirect, DKB or ING, where the flat-rate tax is deducted automatically.

That means: you're legally required (§149 AO, §32d EStG) to declare your capital gains yourself in your tax return. Until now that meant: FIFO by hand, looking up exchange rates, reading up on ETF rules — or hundreds of euros for a tax advisor.

KAPitan does it automatically — for DEGIRO and Interactive Brokers, with more brokers to follow.

German tax law for capital gains is complex. We know every rule.

FIFO cost basis calculation

Gains and losses calculated using FIFO — even across multiple years.

ETF-Teilfreistellung

Equity ETFs (30%), mixed funds (15%), other funds (0%) — tax-free portion calculated automatically.

Vorabpauschale

For accumulating ETFs under §18 InvStG — including the BMF base rate and price-appreciation cap.

Withholding tax (line 41)

Creditable foreign withholding taxes on dividends are identified and reported.

Loss offset buckets

Bucket 1 (equities) and Bucket 2 (other) tracked separately — exactly as the tax office expects.

Currency conversion

USD, GBP and all other foreign currencies automatically converted using the ECB daily rate.

Frequently asked questions

Short answers to the most important questions

How much time does KAPitan really save me?

Most users are done in under five minutes: export the file, upload, done. Without KAPitan that means hours of FIFO spreadsheets in Excel, manually researching exchange rates for every trade, and looking up InvStG rules for ETFs. Or a tax advisor appointment that often costs €200–400.

I invest with a foreign broker — do I really have to report this myself?

Yes. With German brokers (comdirect, DKB, ING), the flat-rate withholding tax is automatically deducted — you don't have to do anything. With foreign brokers like DEGIRO, Interactive Brokers or eToro, this does not happen. You are legally required (§149 AO, §32d EStG) to report your capital gains yourself in your tax return. KAPitan makes this easy.

What is the difference between Anlage KAP and KAP-INV?

Anlage KAP covers equity gains, dividends, interest and losses. Anlage KAP-INV is additionally required for ETFs and investment funds — special rules have applied since 2018 under the Investment Tax Act (InvStG), including partial exemption and Vorabpauschale. KAPitan automatically calculates which lines in which form you need to fill in.

Who's behind it?

Built by someone who had the problem himself.

I'm Philipp — economist & Master in Finance, studied in Cologne and Amsterdam with a focus on Quantitative Finance. I've been investing through foreign brokers myself for years and know the chaos of every January from personal experience: FIFO by hand, looking up exchange rates, reading InvStG paragraphs. I built KAPitan so that no one ever has to do that again.
