One thing I'm interested in regarding SALT is whether the in-game SALT includes regional taxes implicitly.
This was an issue I brought up a lot last year while I was DGM and encouraged some form of 'regionalization' of taxes so we wouldn't have to worry about the question of triple taxation and whatnot. Otherwise you have the situation where regions are assumed to be the in-game analog of states, yet the NPC states are assumed to still be operating largely as if the regions didn't exist.
The reason I bring this up is that if Lincoln's taxes are 'regionalized' (can't remember if they are or not) then the matter of high state taxes in NJ leading to high deductions might not apply here (although iirc Lincoln's taxes are pretty high rn because they tried to balance the budget last year after two years of having no budget whatsoever).
Could there be SALT for the entire region of Lincoln and maybe Fremont?
