Every village/town/city that the RF hs captured will generate taxes. These are calculated according to the population and the town's stability, and every 6 hrs in-game time will be distributed evenly to all online players (minus the Resistance Tax, which is taken off the total first and goes to the Resistance Funds).
Towns still held by the Occupying Faction pay no tax at all.
Paid out at the same time are donations, which come from town support rather than population, and are doubled in towns whose stability is above 75.
If nobody is online when the payout happens, the whole amount goes to the Resistance Funds instead.
