That's so cool, maybe the first time in the history of humanity that we see open source tax software, that's guaranteed to be accurate to the law. For one year at least
It runs Scala / Java, and has docker configs, decent documentation. And an ominous message explaining that some parts were too secret to open source so they had to rewrite chunks of it. Overall, it seems like it was a big project just to get this published, and I am impressed they managed it, given the software team was comprised of 3 different agencies and several contractor firms
