The problem is that taxes are private data at all. Everyone's annual revenue and taxes should be an open data set. The impediment to that is corrupt rich/powerful elites who make a lot of money fudging their taxes, and the industries that serve them - (see Panama Papers). Anyone in the middle class and lower should be pro-open-tax-data. This would lead to less regressive taxes, since we'd see what shady tricks the rich employ, and close those loopholes with legislation. It's a great step to help us iterate on and improve the tax code.
