Title 26 › Subtitle Subtitle A— Income Taxes › Chapter 1— NORMAL TAXES AND SURTAXES › Subchapter R— Election To Determine Corporate Tax on Certain International Shipping Activities Using Per Ton Rate › § 1356
Shipping companies that elect the tonnage tax need to know which of their activities count as "qualifying shipping activities." The core activity is operating qualifying vessels in U.S. foreign trade. Secondary activities also count, such as managing other vessels, providing container or cargo services, hauling cargo inland, and running terminals or repair services tied to the core business, but only up to 20 percent of the gross income from core activities. Incidental shipping-related activities count too, but only up to 0.1 percent of core gross income. For a group of electing companies, these limits are figured as if the group were one entity and then divided among its members.
