Progressive income tax.
Let's consider the top line.
Part of a citizen's income from 0 to 8 is taxed at 5%. On the right we see that it brings 12% of everything that gives income tax. If you click on the number 8, then you can replace it with another value.
Income tax can be made flat. For this, progressive rate must be reduced to 1.
Income tax is not levied on civil servants, as it is assumed that you assign them the optimal salary.
When determining the tax, you can rely on the cost of needs (circled in green).

Demurrage.
Trade button.
On it we see (top to bottom): the amount of monthly inflation, as well as the total amount of money, and the amount of money that is being circulated in the economy.
And the difference between these values is money that people do not spend. For the taxation of money not involved in the economy, scientists suggest introducing a special tax - demurrage.
