I frequently set my taxes to 200% for the first turn or two. Yeah, I get a little unrest, even with patrolling, but not too bad. When I've gotten what I want, then I just set the tax rate back to Automatic, and the AI takes care of it for me.
It's not really that much micro-management. One set of clicks to raise the rate and one more set of clicks to lower it again. Compared to placing your squads and giving them orders for battle, it's positively simple!
