§1353 Notional Shipping Income

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 › § 1353

Last updated Apr 5, 2026|Official source

Summary

A corporation that chooses this tax rule must figure a “notional shipping income” for each qualifying vessel it runs and add those amounts together for the tax year. Notional shipping income: the yearly dollar amount counted for a vessel. Daily notional shipping income: 40 cents for each 100 net tons up to 25,000 net tons, and 20 cents for each 100 net tons above 25,000. To get the amount for a vessel, multiply that daily rate by the number of days the vessel operated in U.S. foreign trade during the tax year. If some of the vessel’s income is excluded from taxable gross income under another rule, reduce the vessel’s notional amount in the same proportion as the included U.S. trade income is to the vessel’s total income. If two or more people operate a vessel, they split the notional amount based on their ownership, charter, and operating shares or by another method the tax agency allows.

(a)For purposes of this subchapter, the notional shipping income of an electing corporation shall be the sum of the amounts determined under subsection (b) for each qualifying vessel operated by such electing corporation.
(b)(1)For purposes of subsection (a), the amount of notional shipping income of an electing corporation for each qualifying vessel for the taxable year shall equal the product of—
(A)the daily notional shipping income, and
(B)the number of days during the taxable year that the electing corporation operated such vessel as a qualifying vessel in United States foreign trade.
(2)In the case of a qualifying vessel any of the income from which is not included in gross income by reason of section 883 or otherwise, the amount of notional shipping income from such vessel for the taxable year shall be the amount which bears the same ratio to such shipping income (determined without regard to this paragraph) as the gross income from the operation of such vessel in the United States foreign trade bears to the sum of such gross income and the income so excluded.
(c)For purposes of subsection (b), the daily notional shipping income from the operation of a qualifying vessel is—
(1)40 cents for each 100 tons of so much of the net tonnage of the vessel as does not exceed 25,000 net tons, and
(2)20 cents for each 100 tons of so much of the net tonnage of the vessel as exceeds 25,000 net tons.
(d)If for any period 2 or more persons are operators of a qualifying vessel, the notional shipping income from the operation of such vessel for such period shall be allocated among such persons on the basis of their respective ownership, charter, and operating agreement interests in such vessel or on such other basis as the Secretary may prescribe by regulations.
