Provincial base tax in 1444.

Taxation is one of the three primary sources of monthly income with production and trade. Each province has a base tax (and eventually an additional tax income) and a tax income efficiency. The yearly province tax amount is simply (base tax + local tax) * (tax efficiency) further modify by local autonomy. Taxation is increased by national tax income besides tax income from provinces so that: \text{Taxation} = \text{Provincial tax income} + \text{National tax income}

Tax income.png Provincial tax income[edit]

Monthly tax income from provinces is:

\text{provincial tax income} = \frac{\text{base tax}+\text{local tax income}}{12} \cdot \text{tax income efficiency} \cdot (1 - \text{local autonomy})

The tax income efficiency includes local modifiers such as buildings and wrong-culture penalties and also national tax modifiers like Advisor Treasurer.png treasurer advisor. The Local autonomy.png Local Autonomy is applied multiplicatively, so if a province has 100% Local Autonomy, the province tax amount will be of 0%.

Base tax and local tax income[edit]

Tax Base Icon.png Base tax is one of the three components of Development.png development in a province, and is an abstract representation of the size and wealth of the population.

The local tax income is a flat amount added to the base tax. Currently, the Native longhouse.png Longhouse native building (+1 Tax income.png tax income) is the only source of local tax income.

Tax income efficiency[edit]

Tax income efficiency is how efficient the government is at squeezing taxes out of a province. The percentages are additive, so for example, if a province in an Government republic.png Oligarchic republic (+5%) is a Core Icon.png core city (+25% and +75%) but it is Combat blockade.png blockaded (-75%), the total tax efficiency will be 30%.

National Tax income[edit]

National Tax income is a special tax income that is not tied to individual provinces, it is added last at your tax income after tax efficiency is applied, so it isn't affected even by national modifiers.

Unlike every other income it is usually expressed as a yearly value in events, so if an event grants a National Tax income to know the actual monthly income the given value must be divided by twelve.
