Sets forth exclusions from gross income for electing entities. Allows a depreciation deduction for qualifying shipping assets for non-operating owners only. Disallows credits and deductions (including those for net operating loss) against tax imposed or income for electing corporations, as specified.

Permits the sale and subsequent replacement of qualifying shipping assets without recognized gain, as specified.

Treats certain income of merchant seaman as foreign earned income and therefore excludable from gross income.
