True, that kind of tax is not taken into account at the moment (simply because I never came across it in my account statement). Based on this it seems its value is proportional to the transaction value.

I've drafted a PR to support it, simply by adding it to the amount of the transaction fees (which is not ideal because it'd end up in "Degiro fees" total, but not sure how else to categorize this at the moment) #121

I would need the complete (anonymized) set of rows of a transaction that exhibit this kind of tax to write a test for it.
