Is an individual who “mines” virtual currency as a trade or business subject to self-employment tax on the income derived from those activities?

If a taxpayer’s “mining” of virtual currency constitutes a trade or business, and the “mining” activity is not undertaken by the taxpayer as an employee, the net earnings from self-employment (generally, gross income derived from carrying on a trade or business less allowable deductions) resulting from those activities constitute selfemployment income and are subject to the self-employment tax. See Chapter 10 of Publication 334, Tax Guide for Small Business, for more information on selfemployment tax and Publication 535, Business Expenses, for more information on determining whether expenses are from a business activity carried on to make a profit.
