People are focused too much on the tooling. Do you think having the government re-write TurboTax software and give it away for free is a good idea? Do you think they would do it cheaper? They literally employee hundreds or even thousands of people to support this software.
You'll pay one way or another, whether its tax payer funding of IRS or through TurboTax. I guess the question is whether you think some government agency can write tax software more efficiently than a private company.
Some people don't understand software and think it doesn't require maintenance, which is especially wrong when you're trying to work with ever changing federal and state tax codes. I'm surprised whenever I see this issue on HN, presumably an engineering heavy group, this idea of "free tax filing software" is so popular.
I'd prefer they simplify the tax code and this problem takes care of itself
