Hi!
Which factors effect tax income of a colony?
Here are factors I know off.
Negative (please note most of those are paid from treasury):
- maintenance costs of buildings on a planet,
- base production (construction and research),
- bonus production from abilities, buildings and econ starbases (you pay only a half of its costs)
- game version (Dark Avarar gives 20% less money from taxation than Dread Lords).
Positive:
- taxation of population and its modifiers (check
wiki for detailed formula):
. amount of population on a planet (revenue calculated by a square root of pop), above 25B pop
seems to be an additional penality,
. taxation level,
. econ ability and bonuses (mining econ resources),
. econ buildings on a planet and Mind Control Center,
. government type.
