None really when compared to the alternatives.
Saved me a ton of time and money. Other tax filing services I looked at charge by the hour at a really high rate. With tokentax I got everything done in a matter of minutes with a concise and straightforward breakdown of capital gains vs income. This is really the best option for people using multiple exchanges (I've used about ten in the past year) and for altcoin traders especially. Highly recommended.Taylor Hawks has used this product for one year.
