Tax calculator: income tax and the military levy on deposit interest, rent, dividends, investment profit or salary - with a note on who hands the tax over and when you pay it yourself
Counts both ways: not only «what is left of the gross» but also «what has to be accrued» for a given amount to reach you - different percentages, and the second one is bigger
A table by income type: the same sum runs through every rate pair at once, so you can see what the identical income costs as a deposit, as rent or as dividends; the table exports to CSV
Article «Tax on passive income»: where it is 23 %, where 10 %, where nothing, why government bonds beat deposits on more than the rate, and why «net» is not «minus 23 %»
