So I’ve just been playing around with the offline version of the software, and I’m still not sure about this and whether the online software is calculating it correctly. This is how the offline version looks:
All three of the fields “Income Days”, “Income During (From)”, and “(To)” are modifiable (and need to be completed), and “Total Days” is calculated from the last two for use in the calculation formula, but it’s not clear to me what the difference between “Income Days” and “Income During”/“Total Days” is intended to be. Neither of these seem to be related to “Resident Days” shown in an earlier tab (315 days for 2022 in my case).
I wonder if this is supposed to be for people entering monthly salary details for each employer/client rather than annual totals?
@qwert_zuiop, did you check with the tax office whether this had been calculated correctly in your case? I’m finding it kind of hard to believe that the income amount should be reduced for days outside Taiwan…
