FlashFiscal is an online tool that simplifies the tax declaration of your income from your securities accounts, especially with brokers like Interactive Brokers (IBKR), Degiro, etc.
It turns your activity statements into a pre-filled PDF form, ready to be copied into your income tax return.
We’re currently compatible with:
Interactive Brokers (MEXEM, ProRealTime, ZoneBourse...)
Swissquote
Degiro
Revolut
Trade Republic
...
See the full list of supported brokers.
FlashFiscal works either from:
Annual reports (often in CSV/PDF format, it depends on the broker)
HTML or ZIP files (for example from Interactive Brokers)
Create an account on app.flashfiscal.com
Import the statements from your broker(s)
Let FlashFiscal automatically analyze the data!
View your tax summary (capital gains or losses, dividends, capital gains…)
Generate your PDFs ready to be reported!
You only pay when you choose to generate the final PDF.
Even better: go to step 3 to get a table containing only the values to copy/paste on the impots.gouv.fr

FlashFiscal does not handle:
Expatriates
Impatriates
US Persons
Legal entities (companies)
We only handle option reporting for Interactive Brokers clients (using their calculation method; that is, including options in the capital gain).
Other than that, options with other brokers are not handled.
