Currently Town Mayors are setting up sales tax with Laws which just feels bad when you're taxed AFTER the transaction is over. It's like hidden fees. I'd love to see the ability to do this via Treasury which shows the total price inside Store UI. The problem is currently it's lacking many options. Tax seller or buyer or both? Tax only citizens or non-citizens or both? Tax only when selling or when buying? Variable rate for citizens/non citizens? Let's make Treasury great again!
