Tax rate

The tax rate is a mechanic that features in several Civilization games. It represents the civilization's budgetary priorities, allocating the turn's gross revenue between different sectors which vary from game to game.
In earlier games, gold is not a direct yield. Instead, cities acquire Trade/Commerce, an abstract quantification of their economic and social activity. The tax rate divides this income between research and innovation, public amenities, and surplus wealth ("tax") that is given to the treasury. In Civilization IV, happiness and culture are funded through the same option; the Beyond the Sword expansion pack introduces a sector for espionage.
In some games, governments may impose a limit to the maximum percentage any sector can be funded.
Adjustable tax rates were removed in Civilization V and later games, which instead rely on direct yields from terrain and improvements.
