the good reason: some people are philosophically opposed to easy taxes - people should be painfully aware of the money they are giving to the government. (sort of like folks who have VAT complain about advertised US retail prices which don't include tax)
The bad reason: Lobbying by intuit and parties to prevent easy tax preparation. Their ROI on regulatory capture is very very good.
