"Ottoman base tax compared to Karamanese -72" ...

[stevieji]

...just for example, from my current game ... "Ottoman base tax compared to Karamanese -72" ...
I don't understand the objection - is base tax too high or too low?
Why should this matter, either way?
For capital province, or average for whole country?
Is there any way to change this, or should I just give up on diplomatic annexation?

+30 to -90 from base tax. Determined by 60*(your base tax)/(target's base tax)^2 - 90, where base tax is the total province base tax of the country without any buildings or modifiers. In addition the base tax of your vassals multiplied with your vassal income efficiency counts towards your base tax

Yours is to low and theirs is to high.

Since the formula compares (your base tax) with (target's base tax)^2, you will really want to just annex/vassalize them by force.
