Idaho has a very small tax base, so they have to tax what's there at a higher rate. At the same time, what a lot of people like about Idaho is vast amounts of wilderness and unspoiled nature. If somebody loves to hike in the mountains, they're sooner going to pay 7% income tax and live in Idaho than move to Florida or Texas. It's the luxury of choice that someone making 100k/year in Idaho can afford.
