If you are a fief owner, you basically have three options about taxes :
- you dont change it (5%) or even lower it (to 0% or even less, if you want to reward trade, but its rare), and you OPEN YOUR BORDERS = congratulations, you are a selfless
moron good person, but you will not have a lot of money and will die if faced with a faction of the same size which have closed borders and billions of plate armors +3, which will then annex your fief and close its borders.
- you dont change it (5%) or even lower it (to 0% or even less, if you want to reward trade, but its rare) = most fief owners do that because they can spend their PP on more important thing, but then they have to be REALLY careful about SD thiefs, because default tax (5%) doesnt bring enough gold to the bank = most fief owners close their borders and kill traders on sight, and try to use their own S&D themselves (greedy bastards!)
- you change it to more than 5%, lets say to 30% (which is the average trade cut you can ask on a trade agreement where you use someone's else S&D and MANUALLY have to drop a part of your benefit/goods bough in the fief), then you are a satisfied person whenever someone buy/sell from your fief, and you can open your borders, everyone's happy.....
BUT WHAT THE FUCK IT WOULD COST 125 PP JUST TO DO THAT !
