Taxes
Taxes are the flow of money into your government. They represent all revenue above and beyond the regular day to day expenses such as paying wages for bureaucrats and the likes. Taxes can be used to upgrade your system, increase trade and build projects of all sorts.
Taxes are generated from sets of Products. A tax set is formed by combining 3, 6, 9 or 12 different products. The following table gives the revenue produced by each of these sizes, and an example of each set size.
| Set Size | Tax / Set | Example |
|---|---|---|
| 3 | 1  |  + + |
| 6 | 3 |  + +++ + |
| 9 | 6 |  ++ ++++ ++ |
| 12 | 9 | +++++ ++++++ |
Note that since products represent a flow of products, you cannot save up products until you have enough to form a tax set - you either have them by the end of the turn, or you lose them. Likewise, you must either spend taxes or lose them.
The total amount of taxes that can be generated is limited by the Population size. You can create 250 Tax sets per 1
billion inhabitants total in your system. Note that this is a limit on the number of sets, not the total amount of taxes!
