This Tax Brief focuses on U.S. federal income tax consequences of investing in cryptocurrencies on a regular or long-term basis. It is not intended for cryptocurrency miners or those holding cryptocurrencies for sale to customers. There are on-line sources describing how to calculate your gains and losses from cryptocurrency trades, but there is a lack of guidance on planning cryptocurrency investments to minimize taxes. This Tax Brief is written from the perspective of an experienced tax attorney and discusses successful tax-planning techniques he has developed through decades of research and experience.
