alt Hacker NewsThis is great that this is out there. I've been working on making an agent based experience that helps you put together your whole return or make an estimated return based on future assumptions and solving for the federal tax code has been a very token expensive operation!

I'm going through their engine as well and validating mine. My engine is built to include the CA tax code also.
The biggest reason that turbo tax and the other companies survive though is that in order to allow efile you have to be a registered agent and that process is crazy expensive and difficult.
can you explain your validation process?
I'd be tempted to try something similar for this season. But this is what I generally pay HR Block for; they should be relatively vetted (granted i don't know this for a fact).
like do you have tax accounting experience or do you intend to have someone who does help validate test returns to make sure they look right?
