You must include in gross income in the year of receipt the fair market value of goods or services received from bartering. Generally, you report this income on Form 1040, Schedule C.pdf, Profit or Loss from Business (Sole Proprietorship), or Form 1040, Schedule C-EZ.pdf, Net Profit from Business (Sole Proprietorship). If you failed to report this income, correct your return by filing a Form 1040X.pdf, Amended U.S. Individual Income Tax Return. Refer to Topic No. 308 and Should I File an Amended Return? for information on filing an amended return.
When barter has appeared, it wasn’t as part of a purely barter economy, and money didn’t emerge from it—rather, it emerged from money. After Rome fell, for instance, Europeans used barter as a substitute for the Roman currency people had gotten used to. “In most of the cases we know about, [barter] takes place between people who are familiar with the use of money, but for one reason or another, don’t have a lot of it around,” explains David Graeber, an anthropology professor at the London School of Economics.
