Title 26 › Subtitle Subtitle A— Income Taxes › Chapter 1— NORMAL TAXES AND SURTAXES › Subchapter N— Tax Based on Income From Sources Within or Without the United States › Part V— INTERNATIONAL BOYCOTT DETERMINATIONS › § 999
Requires taxpayers to tell the IRS if they, a related company, or a foreign company they partly own took part in, helped with, or were asked to take part in an international boycott during the tax year. The IRS keeps a list, updated at least every three months, of countries that may demand boycott cooperation. Report what kind of operation was involved. If any member of a group of related companies takes part in a boycott, the rule treats all the group’s business in that country (and in other countries that require boycott cooperation) as if it took part too, unless the taxpayer can clearly show a particular operation was separate and did not cooperate. The law allows narrow exceptions when U.S. law, regulations, or an executive order requires the boycott or when a country bans imports or exports. Key terms: controlled group — related companies treated together for these rules; participation/cooperation — agreeing to refuse business, refuse U.S. partners, exclude people or directors for nationality/race/religion, refuse to hire, or limit shipping to certain carriers; world-wide operations — business outside the United States; international boycott factor — a fraction used to limit certain tax benefits based on how much business was tied to boycott countries. The IRS can decide, even in advance, whether an operation counts. Willfully failing to report can lead to a fine up to $25,000, up to one year in prison, or both.
