  • No. UltraTax CS Express does not have all of the same functionality as UltraTax CS. You should purchase UltraTax CS if you need more than one user, need more than 100 returns a year, or access to the Oil and Gas module. You should also consider UltraTax CS if you need forms beyond 1040, 1120, 1065, 1041, and 990 or if you need to file returns in more than ten states.

  • Absolutely. UltraTax CS offers organizers and data collection tools, to ask your clients questions about their use of virtual currencies. Data mining functionality within UltraTax CS could help you target these clients, and proactively communicate next step information in a client newsletter.

    Here are the most common scenarios when virtual currency has tax implications:

    • Selling / Exchanging – The sale or exchange of virtual currency, including for goods or services in commercial transactions, must be included as a capital gain or loss.
    • Mining – Virtual currency that was mined must be included in gross income. If this constitutes a trade or business and the mining activity is not undertaken by the taxpayer as an employee, then the net earnings resulting from those activities constitute self-employment income and are subject to the self-employment tax.
    • Compensation – Virtual currency received as payment for goods or services must also be included in gross income.
    • Payments – Wages paid or payments made to an independent contractor, employee, or other service provider using virtual currency must be considered.
