Can't seem anything related to 'taxes'. Am I missing on something? Moreover, what is a crypto tax application? Your descriptions seem more like crypto-tracking. Is the build version compiles into an electron App? The demo on the repo isn't working. Nice to see some React and Ts work done here 
I'd probably contribute for learning TS sakes.
I'd probably contribute for learning TS sakes.I think your missing something, if you go to the demo and close the getting started popup then go to the `Calculate Gains` Tab this is will tax would be calculated.You would press the customize button and then select the year and the method etc.... By default there is no data loaded so youd need to manually add some trades or import some from an exchange to get a better idea of how it all works. I have on my feature list already to add a demo mode that will just randomly add some trades so you can play around, but havent had the time to work on that yet.
Yes the build or desktop version using electron. It should just be a matter of cloning the repo, running install and then start.
As for the web app/demo not working, could you clarify exactly what doesnt work?
Feel free to contribute, happy to have help wherever possible
