Do the AIs use the modded rates, or do they still just use the base rates?
O.k. Did some further test. While the ability to change the tax rate is not hardcoded, the ability to use them seems to be. The AI will use:

This was my concern as well when I was tweaking the taxrate system (currently the one in LH 1.3). The AI will use your modded rates, but I don't think the AI use tax rates in the first place. They just leave it on the opening setting the entire game. Thus I was very careful not to throw the normal tax rate too far off from what SD originally had set, and I build the remainder of my curve from that point...
Yeah, I made sure the unrest follow the curve you built. I think I did a pretty good job!
imo, if you did that, you don't really have to worry if the AI doesn't want to use the extra rates. The curve is the same and thus and impact of tax is the same. Sure, they'll have less precision....but since when is AI about precision??
