Yeah I agree it would be a lot of work. I was thinking that it could start with support for a few major countries and branch out from there. I bet there would be ways to monetise with premium features like Rotki. It is not exactly an idea I would excited to work on, but feels like something that is super important to get the circular economy happening. I want to get merchants accepting Bitcoin, but I also feel like I need to inform them of the tax burden involved. It would be great if it was recognised as legal tender everywhere instead, maybe the effort is best spent there?

That would be country dependent plus tax rules might change every year, so that's a lot of work.

Probably only commercial products like koinly will be bothered to do all that.

Maybe an open source alternative with paid support might appear though.

Bitcoin Only Tax and Accounting Software

After playing around with it for a bit, it looks solid. I reckon a Bitcoin focused app that is similar to Rotki but also exports tax forms like Koinly does would be killer.
