when you send a caravan out with gold to buy and it doesn't return within the same tax period. where does the gold go?
let's say you have a normal tax week income of 1k gold (minus the other maintenance bits, before splitting with knights, etc)
the day before the tax day your auto caravan went out with 300 gold to buy. does that mean net tax income will be 700?
(probably matters most with high price buying, especially when caravans get spammed and return with no food)
The gold is on the caravan, and can be stolen.
I think your net tax income example is correct.
