Welcome!

I'm Robert Karl, creator of Velvetax. I started trading bitcoin in 2015. When I needed to file my taxes, I wanted a powerful, easy, and reasonably priced crypto tax calculator.

So I built Velvetax! The project started as an open source command line utility and was launched as a website in 2019.

Open Source

We love open source. So we created the yabc open source crypto tax calculation kernel.

Did you know you can use our open source library to calculate your crypto taxes on the command line -- with a free and permissive license?
