Calculation of column "usd_gains"
sebastianhaberey opened this issue · 6 comments
Hi @laroche,
This is a tax law question rather than an issue: Why is the usd_gains column calculated the way it is? I can see that there's values in this column when option positions are opened and no values when they are closed. I'd have expected it the other way around, but my knowledge of the tax law isn't great. Could you explain why Währungsgewinne are calculated that way (or point me to an article)?
Hello Sebastian,
usd_gains are calculated on the cash, so buying a stock sells usd and that is the time
you are using FIFO to calculate the tax gains. (So if you are opening a long option position, that's
exactly the same as with stock. Short selling is the opposite...)
General info about all this:

Ok, thanks! One question though: wouldn't you have to know the initial exchange rate for this? I mean, the exchange rate that was applied when I transferred the money to my Tastyworks account?
Correct. You need to input a complete transaction set to get correct output for all FIFO calculations.
If you then specify a certain tax year, only the output is limited to that time period.
So how do you figure out the exchange rate of the initial transfer, since it's not in the input data? Do you just take the exchange rate valid on the day of transfer?
Exchange rates are from bundesbank.de.
