For purposes of the U.S. Internal Revenue Code, a barter transaction is in substance the same as a sales transaction. For example, the exchange of a mailing list for advertising space is the essential equivalent of selling the mailing list for the value of the advertising space. The value of the advertising space is considered to be income to SLA. The comments made in the Tax Status section concerning SLA's tax liability for related business income and unrelated business income will equally apply to value received on bartering transaction. An example of barter which would generate related income would be an exchange of SLA publications for something of value. An example involving unrelated income would be the one just given, namely, the exchange of a mailing list for something of value, except when this exchange is with another organization exempt under Section 501(c)(3) or (c)(2). The sporadic and occasional bartering transaction of whatever character arguably does not constitute business income of any kind. In all events, every barter exchange transaction by any Chapter or Division should be reported, in writing, to the Director, Finance at the Association office.
